Description

The invention relates firstly to a lamp socket according to claim 6, a lamp socket according to claim 1, a system for mechanically fixing a lamp socket in a lamp socket according to claim 7 and a method for mechanically fixing a lamp socket in a lamp socket according to claim 11.

From the prior art double ended lamps, in particular fluorescent lamps are well known. For example, on the DE 10 2007 054 930 A1 referred to the applicant. Such double capped, tubular fluorescent lamps have at their respective ends socket contacts in the form of contact pins, which are each inserted into a socket. These are generally sockets with a rotor, in which the contact pins are fed via a slot in the socket housing the rotor and moved by subsequent rotation of the lamp with the rotor driving in both a contact position in which the socket contacts with the contact pins of Lamp enter an electrical connection, as well as the mechanical support is achieved.

In their handling, however, they have some disadvantages when inserting and disassembling the lamp, since the socket pins of both lamp ends are usually not synchronously used in the versions, which is due on the one hand in the handling by the user, and its cause is that the insertion of the socket contact pins into the narrow insertion openings of the sockets is imprecise. The longer the fluorescent lamp itself is the more uncomfortable is the handling. The user has to pay close attention to the low inherent stability of the fluorescent lamps, not to destroy the lamp when inserting or accidentally dropping it.

Then comparatively elongated single-ended fluorescent lamps are known from the prior art, which are used in luminaires with only one socket. In order to reduce the mechanical stress on the socket and to ensure correct alignment of the lamp in the lamp, these lamps can be provided with an additional holder for the fluorescent lamp, which is usually a locking element. This partially surrounds the fluorescent lamp, which itself has no additional holding means. Reference is made to Articles 26.746.1001 and 26.726-013 shown in Catalog 2008-2011 on pages [03] 52 to [03] 54 of the Applicant. In such systems, the assembly of the fluorescent lamp by inserting it sideways regularly good. In general, not inconsiderable forces must be applied to insert the lamp in the socket. However, since the lamp socket mount provides a final assembly travel end stop, the user has the assurance that he will not lose the lamp by mistake. The same applies to the engagement of the lamp in the light-side holding element. Again, the holding element offers a Montageendanschlag for the fixing movement. Much more uncomfortable for the user is the disassembly of such a fluorescent lamp, since here with relatively high effort the sensitive fluorescent lamp from the latching retaining element of the lamp and then has to be pulled out of the lamp socket. The usually sudden overcoming of the holding forces of the holding element and the socket results in a sudden movement of the lamp in the dismounting direction, with the risk that the lamp is accidentally dropped or abuts against the lamp housing.

Finally, LED lamps are known as a substitute for such fluorescent lamps from the printed documentation not assignable prior art. However, these use the known socket and socket systems. In order to be able to serve as a retrofit or replacement lamp for existing luminaires, such LED lamps are also modeled on the classic fluorescent lamps in their design.

From the DE 696 06 700 T2 is a push-in push-out arrangement of socket and socket known in which the entire mechanism is arranged alone in the socket and separate holding parts mechanically anchor the socket in the socket.

The object of the invention is to improve the mounting of a lamp, in particular an LED lamp in a luminaire.

The object is achieved first of all by a lamp cap having the features of claim 1.

This lamp base is provided with a mounting dome suitable for insertion into a lamp socket having a spring return resiliently hinged retaining pin for mechanically anchoring the socket, the mounting dome being provided with guide surfaces forming a path of movement along which the retaining pin is guidable, the trajectory is suitable for deflecting the retaining pin by means of a Auslenkabschnitts under construction of a spring tension from a rest position in a first direction, by means of a return section with partial reduction of the spring tension in the direction of its rest position, while maintaining a residual spring tension in a locking section to hold, which is part of the return section.

Such a lamp cap is part of a so-called push-in push-out arrangement, in which the lamp cap is held by pressing into the socket in an anchoring position and is guided by re-impressions in the version in a release or disassembly position. When the first depression of the socket into the socket, the holding pin arranged in the socket is moved into the locking section of the socket and thus holds the socket in an assembly position. In this there is a mechanical anchoring of the base in the socket and thus a lamp in a lamp instead. Also, an electrical connection between the socket and socket-side contacts is given in this state.

In a corresponding development of the socket according to the invention it is provided that the movement path is suitable for further relative movement of socket and socket to release the retaining pin from the locking section, to reduce the spring back tension from the return section into an Ausführabschnitt the trajectory.

The main advantage is now to be seen in the fact that a renewed pressing of the socket in the socket releases the retaining pin from the locking portion and transferred to the Ausführabschnitt, so that the base can be taken out of the socket out. In this case, when removing the socket from the socket in this embodiment, no significant effort is needed. Rather, the base slides out of the socket almost independently. At most, a certain frictional engagement may hold the base taking into account the weight of the lamp connected to the socket in the socket.

To prevent accidental slipping out of the base of the socket and the lamp so in a deliberate or accidental Releasing the retaining pin from the locking portion to hold in the socket, it is provided that the Ausführabschnitt is adapted to deflect the retaining pin with re-establishing a spring tension in a second direction, which is opposite to the first deflection.

The main advantage here is to be seen in the fact that the retaining pin can slip out only under construction of a renewed spring tension through the Ausführabschnitt. This spring tension is dimensioned so that it readily prevents slipping out of the retaining pin from the locking portion solely due to the weight of the lamp.

Finally, it is provided that the guide surfaces belong to a guide groove incorporated in a side wall of the mounting dome.

It is further provided that the guide groove springs from an inlet opening, through which the retaining pin is inserted into the groove and terminates in an outlet opening, through which the retaining pin can be removed.

For a cooperation with the above-described lamp socket a correspondingly designed version is required. Thus, part of the invention is also a socket according to claim 6, with a recess for receiving a mounting dome of a lamp base, in which a spring-loaded pressure plate is arranged and arranged in the recess retaining pin which is hinged spring return elastic and optionally with socket contacts for electrical connection Contacts of a lamp socket.

The main advantage of this version can be seen in their interaction with the aforementioned base, which realize a so-called push-in - push-out principle for anchoring the base in the socket. This is characterized by the fact that a depression of the base in the socket initially leads to a mechanical anchoring and electrical contact and leads a renewed impressions of the lamp cap in the socket to a detachment of the socket from the socket. The central element here is the socket-side retaining pin, which is first moved via the spring return elastic deflection in cooperation with the guide surfaces of the lamp cap in a locking position and then in a release position. The spring-loaded pressure plate ensures that the retaining pin safely remains in the socket-side locking portion and is moved out of the socket after re-pressing the socket in the socket.

It is then part of the invention, a system for mechanically fixing a socket according to claim 7 in a socket according to claim 6 wherein the mounting dome of the base is mounted in the mounting direction in the receiving space of the socket, the pressure plate under construction of a spring tension by the mounting dome from your Resting position is displaced and the pressure plate against the mounting direction urgently holding the retaining pin of the socket in the locking portion and thus the socket in the socket.

The system according to the invention is characterized in that the retaining pin is released from the locking section by renewed movement of the mounting mandrel in the mounting direction and further displacement of the pressure plate and transferred to the embodiment section.

Furthermore, it is provided that the spring tension of the pressure plate induces a disassembly movement of the mounting dome, which moves the retaining pin along the Ausführabschnitts and causes a spring return elastic deflection thereof.

Then - as already mentioned above - the system is able to ensure that the frictional engagement between the spring restoring elastic deflected in the Ausführabschnitt retaining pin and the guide surface of the Ausführabschnitts holding pin in the Ausführabschnitt and prevents leaving the retaining pin through the outlet opening.

Furthermore, a component of the invention is a method for mechanically fixing a socket in a socket, characterized in that the mounting dome is inserted by means of a mounting movement in a mounting direction in the recess of the holder, wherein the retaining pin meets at least one guide surface of the Auslenkabschnitts and the pressure plate of Bracket is moved under construction of a spring tension by a first distance.

This is further developed by the retaining pin over the assembly movement away along the deflection portion of the movement path slides and at the end of the assembly movement in the return section dips until it is anchored in the locking portion.

Then it is provided that a disassembly movement is performed to release the locked retaining pin, which is initially the same direction with the assembly movement.

Finally, the method is developed by moving the retaining pin in carrying out the disassembly movement in the Ausführabschnitt.

It is also provided that, in continuation of the disassembly, reversing the direction of movement of the retaining pin is guided under renewed elastic spring return elastic deflection through the Ausführabschnitt the trajectory.

And finally, it is provided that the continued disassembly movement is induced with movement direction against the mounting movement of the spring-loaded pressure plate of the socket.

In the figures, a luminaire according to the invention is provided overall with the reference numeral 10. It is in perspective view in FIG. 1 shown.

The lamp 10 receives at least one, in the present embodiment, however, a plurality of elongated, assembled into a line-like light band lamps 11. For mechanical anchoring of the lamp 11, the lamp 10 has a holder 12 which cooperates with a holding part 13 of the lamp 11. The holder 12 and the holding part 13 are used exclusively for the mechanical fixing of the lamp 11 to the lamp 10, whereas a light-side socket 14 and a lamp-side base 15 of the mechanical anchoring of the lamp 11 in the lamp 10 and the electrical connection serve. The base 15 is arranged at a first end of the lamp 11, the holding part 13 at a second end of the lamp 11 so that the lamp type according to the invention is a double-sided lamp type.

The lamp 10 is kept fairly simple in the embodiment. This is a carrier in H-shape with two spaced apart vertical legs 16 and a horizontal leg connecting them 17. The lamp 10 forms in this way a viewer facing receiving space 18 for the lamp 11 and a supply space 19, the viewer is facing away and which receives the socket 14, the holder 12 fasteners for the arrangement of the lamp to building parts and, for example, live cables and control cables.

The lamp itself is designed as an LED lamp, which not only has advantageous properties in terms of energy consumption, but in which the light direction can be influenced by the arrangement of the individual LEDs. In this way, by the base 15 and the Holding part 13 shaded space between two consecutively arranged lamps 11 are illuminated for the viewer, so that a light band with continuous uniform light emission arises.

The holder 12 is alone in the FIGS. 3 to 5 shown. In the bottom view ( FIG. 3 ) is first apparent that the holder 12 forms a substantially cup-shaped base body, the bottom 20 holds two opposite end walls 21 and 22. Between the end walls 21 and 22, two side walls 23 and 24 are held. The bottom 20, the end walls 21 and 22 and the side walls 23 and 24 form a receiving space 25 which is accessible via an opening 26. The opening 26 is divided in the direction of a direction of insertion X in a front insertion portion 27 and a rear insertion X in the holding portion 28. The holding portion 28 is defined by two spaced opposite, in the insertion direction X-oriented webs 29, the opening 26 in Narrow the region of the holding portion 28 groove-forming, so that the holding portion 28 is formed as a kind of undercut retaining groove. The holding portion 28 is formed in the insertion direction X so long that at least the production-related length tolerances of the lamps 11 are compensated. However, it is preferable to also provide a space for compensating the thermal expansion of the lamp 11, as will be described later.

In the receiving space 25 of the holder 12 guide surfaces 30 are arranged, which serve to control the insertion movement in the insertion direction X of a holding part 13. The guide surfaces 30 originate from the first end wall 21, close to the opening 26, drop toward the bottom 20 and run parallel to the ground in the region of the holding section 28. Between the webs 29 and the bottom 20 so a holding space 31 of the holding portion 28 is formed.

As seen from the perspective view of the holder 12 in FIG. 4 shows, the side walls 23 and 24 are provided with locking means 32 which serve to anchor the holding part 13 in the cutout of a lamp component. A circumferential collar 33 on the edge of the holder 12 facing the lamp 11 serves as an abutment, which prevents slippage of the holder 12 by the aforementioned cutout of a lamp component. However, it is also conceivable that the holder is integrally integral part of a lamp component and not, as proposed here, is made as a separate component for equipping a lamp.

The sectional view of the holder 12 along the section line AA in FIG. 3 illustrates on the one hand in particular the presence of the holding space 31 in the holding portion 28 and the course of the guide surface 30. This falls - starting from its opening near origin in the first end wall 21 - along a circular path section to about the level of the bottom 20 from. Alternatively, however, the sloping course may take another form. This corresponds preferably with the part to be used 13th

With the holder 12 corresponds to the mechanical fixing of the lamp 11 in the lamp 10, a holding part 13, which in a perspective view in FIG. 6 is shown.

The holding part 13 of the invention sits on the end of the lamp 11 and thus forms part of the lamp housing. For this purpose, a holding part bottom 34 holding part side walls 35, which has a in FIG. 6 away from the viewer away receiving space for lamp components form. The holding member 13 is therefore formed as a cap, which is attachable to the end of the lamp 11 and, for example, holding elements for a cover glass 43 and a board 44 which is provided with LEDs 45, formed. The holding part 13 is facing one of the lamp Holding part side wall 35 with an anchor portion 36 for mechanically fixing the lamp 11 to the lamp 10 is provided. This anchor portion 36 forms an anchor pin 37, which springs from the holding part side wall 35 and carries an anchor head 38 at its free end. The anchor portion 36 is configured so far in an approximately T-shaped. The end portions 39 of the anchor head 38 are shaped roughly like a roll.

In FIG. 6a is now an alternative embodiment of the holder 13 according to FIG. 5 shown. This differs from the holder 13 according to FIG. 5 in particular in that in the receiving space 25, a spring element 40 is arranged, the spring arm 41 is arranged in the holding space 31. The spring arm 41 is displaced upon insertion of the holding part 13 in the holder 12 from the anchor portion 36 in the insertion direction X from its rest position out. As an alternative to the leaf spring element selected here are other spring elements, such. B. coil springs conceivable that are displaced from a rest position out in the insertion direction X, when the holding part 13 is inserted into the holder 12.

The holding part 13 and the holder 12 act together as a system for mechanically fixing a lamp 11 in a lamp 12. The nature of this interaction and the operation of inserting the holding member 13 in the holder 12 will now be made recourse to the illustration of FIG. 7 explained in more detail.

FIG. 7 is a partial sectional view of the lamp 10 according to FIG. 1 with a view of the arrangement region of the holder 12 and holding part 13. From the lamp 10 itself, only the horizontal leg 17 of the H-like trained lighting profile is shown. In a recess 42 of the horizontal leg 17, the holder 12 is locked.

An end portion of the lamp 11 in sectional view is also in FIG. 7 seen. From this it is apparent that the holding part 13 with its holding part bottom 34 and its holding part walls 35 forms a receiving space for lamp components. Within this unspecified receiving space end portions of the lamp cover 43 and a circuit board 44 are held, wherein the board 44 is provided with a series of LEDs 45.

The lamp 10 facing the holding part side wall 35 carries - as already mentioned - the anchor portion 36 which is below the bracket 12 in front of the opening 26 in the region of the insertion portion 27 is to be arranged. The anchor head 38 is now inserted in the insertion direction Y through the opening 26 in the receiving space 25 of the holding part and then slides on the guide surfaces 30 in the insertion direction X from to immerse in the holding space 31 of the holder 12.

The now engaging in the area of the undercut anchor head 38 has the connection between the webs 29 out of the holder 12 further armature pin 37 connection to the lamp 11 and holds it against the direction of gravity of the lamp 10. The advantageous roller-like configuration of the end portions 39 of the anchor head 38 allowed pivoting the lamp 11, which in this state is only one-sided mechanically held on the lamp 10, around the anchor head 38 as the center of the pivoting movement. This is advantageous with regard to the connection of socket 15 and socket 14, which will be described later.

From the illustrated interaction of holder 12 and holding member 13 will be immediately apparent to anyone that the structural features of the holder 12 may be formed on the side of the lamp 11 in the sense of a holding part, if the structural features of the holding part 13, in particular the formation of the anchor portion 36 on the part of Lamp 10 are formed. In this respect, such an exchange, ie the retaining part 13 as a feature form the holder 12 and at the same time form the holder 12 feature as the holding part 13, to be regarded as equivalent.

The FIG. 9 is one of the FIG. 7 corresponding representation, but here a holder 12 was used on the light side, the modified embodiment of the FIG. 6A equivalent. It was therefore supplemented by a spring element with spring arm 41. Again, the assembly process of the holding part 13 in the holder 12 initially according to the description FIG. 7 run.

However, in order to complete the assembly process, in which the lamp must be moved to an end stop in the insertion direction X, the spring arm 41 is displaced by the anchor head 38 from its rest position and builds against the insertion movement X directed spring force. This has the consequence that when dismantling the lamp 11, including a release of the socket and socket is necessary (see below) by the spring arm 41, an ejection movement is induced. In this case, the spring forces urge anchor head 38 in a direction opposite to the insertion movement X direction until the spring arm 41 has reached its rest position. It should be noted, however, that in a particularly preferred embodiment, the anchor head 38 is moved by the spring arm 41 during disassembly of the lamp 11 in the direction of the insertion portion 27 of the holder 12, but does not get into this. Instead, it remains in the holding portion 28, so that the transition into the insertion portion 27 and thus a gravity-induced sliding out of the anchor portion 36 from the holder 12 does not take place.

In this context is on FIG. 8 Reference is made to a simplified partial view of a side view of the lamp 10 in Area of two consecutively arranged lamps 11 shows. In this illustration, the vertical leg 16 of the lamp 10 have been omitted. The anchor portion 36 together with the holding part 13 has been shown by dashed lines in two different positions. In a spaced-apart arrangement of the lamps 11, the anchor head 38 has approximately in the FIGS. 7 and 9 shown position in the holding portion 28 of the holder 12. By continuing the insertion movement X reach the lamps 11 in the immediate vicinity.

The lamp 11, of which the base 15 provided with end portion is shown, wherein the base 15 is anchored in the socket 14, is already fully assembled, so that it is forced in the direction of X with respect to the above-described operation no movement.

Based on Figures 10 and 10a Now another embodiment of the holder and holding part will be described. Both are provided in the present embodiment with contacts that form an electrical connection in the assembled state of the lamp 11. In that regard, the holder and the holding part of this alternative embodiment are designed as a socket 14 and socket 15 and are referred to below. However, since mechanical anchoring forms the gist of the invention, this term choice is not intended to be limiting. at FIG. 10 it is a simplified partial sectional view of the lamp 10 according to FIG. 1 showing the arrangement area of socket 14 and socket 15. FIG. 10a on the other hand shows a view in the direction of insertion X on the base 15 and the socket 14, wherein in the version 14, the in FIG. 10 shown, front in the direction of insertion X front housing wall 50 is broken away. FIG. 10b finally shows a perspective view of the lamp base 15 in the insertion direction.

The lamp base 15 initially forms, similar to the holding part 13, a pot-shaped recess for different lamp components, as is evident in particular from the sectional view of FIG FIG. 10 is apparent. Mirrored to the holding part 13 and this recess also assumes the lamp cover 43 and the board 44 in an analogous manner.

As first from the perspective view in FIG. 10b It can be seen, the lamp base 15 has a pointing in the direction of light fitting assembly 51 51, the contact recesses 52 forms, in which base contacts 53 are seated. Upstream of the contact recesses 52 in the direction of insertion X, a fastening section 54 is located whose front surface facing the front housing wall 50 in the insertion direction X forms a guide groove 55 which forms guide surfaces for a retaining pin 56 of the socket 14. This guide surfaces form a trajectory along which the retaining pin 56 is feasible, as will be explained in detail later.

The front view of the lamp holder 15 in Figure 10A is particularly suitable to explain the individual sections of the guide surfaces and the guide groove 55.

The guide groove 55 springs from a socket 14 facing the inlet opening 57, which is aligned with a free end portion 58 of the retaining pin 56 and is arranged in the embodiment in a lamp longitudinal axial, directed vertically to the horizontal leg 17 level.

Starting from the inlet opening 57, the guide groove 55 initially forms the so-called deflection section 59. This is guided at an angle to the aforementioned vertical plane and merges into a wave-like return section 60. This return section contains about it In addition, a locking portion 61 and passes into the Ausführabschnitt 62, which in turn opens itself in an outlet opening 63.

In the Figure 10A also shown socket 14 has a socket recess 64 which is formed substantially complementary shape to the mounting dome 51 of the base 15. The aforementioned holding pin 56 of the socket 14 is fixed at one end in the socket housing 65 and directed in the direction of the insertion opening 66 with its free end portion 58. Via the insertion opening 66, which faces the base 15, the mounting dome 51 can be introduced into the socket recess 64.

The retaining pin 56 is also in the aforementioned vertical plane in the embodiment shown here. For the post-described function, however, it is urgently significant that it is aligned with the inlet opening 57 of the guide groove 55. The retaining pin 56 is also formed Federrückstellelastisch and preferably consists of a spring steel wire, wherein the free end portion formed by bending in the insertion direction X a locking tab 67, as the lamp longitudinal section according to FIG. 10 shows. For a better overview, see Figure 10A in deviation from FIG. 10 not shown arranged in the socket recess 64 pressure plate 68, which can be pressure-loaded via at least one coil spring 69.

Finally, the socket 14 forms a contact space 70, in which socket contacts can be arranged, the contacts with the socket 53 enter into an electrical connection.

Version 14 and the base 15 in their interaction form a system for mechanically fixing the lamp cap 15 in the socket 14 and thus a system for mechanically supporting the lamp 11 in the lamp 10 while ensuring a corresponding power supply and - if necessary - the electrical connection of control lines, with which, for example, light color and light intensity of an LED lamp 11 can be influenced. This also implies a mounting method for inserting a lamp cap 15 in a lamp socket 14. This will now be described with reference to FIGS FIGS. 11 to 14 continue running.

The FIGS. 11a . 12a . 13a and 14a each show a side view of the lamp 10 in the arrangement region of the base 15 and socket 14 and differ only in their respective arrangement position between the lamp 11 and lamp 10. In particular, the different immersion depth of the mounting pin 51 of the base 15 in the socket recess 64 of the socket 14 is shown , The corresponding representations 11b, 12b and 12c, 13b and 13c and 14b are those which the FIG. 10a are modeled. These are therefore views of the arrangement region of the socket 14 and base 15 in the insertion direction X, wherein the front housing wall 50 of the socket 14 is broken away.

The insertion of the base 15 in the socket 14 and their interaction for the mechanical anchoring of the lamp 11 in the lamp 10 will now be shown below.

FIG. 11a shows a pre-assembly in which the base 15 is arranged with its mounting dome 51 of the socket 14 and the socket recess 64 facing. Again FIG. 11 It can be seen b, is the spring restoring elastic deflectable retaining pin 56 in its rest position, its locking tab 67 is the inlet opening 57 of the guide groove 55 facing.

In FIG. 12 is now shown that the mounting dome 51 through the insertion opening 66 of the socket 14 through a first piece in the Socket recess 64 was moved into it. The locking tab 67 of the retaining pin 56 dives through the inlet opening 57 of the guide groove 55 in the same (see FIG. 12b ). This is done by the mounting dome 51 and the base 15 is moved in the insertion direction Z. In a continuation of the movement, the locking tab 67 slides along the deflection portion 59 of the guide groove 55, whereby the retaining pin 56 is deflected spring return resiliently from its rest position. In this case, the deflection section 59 encloses an angle with a plane directed vertically to the horizontal limb 17 and extends along the length of the lamp axis and is inclined in the insertion direction Z to this plane.

As FIG. 12c shows the locking tab 67 after completion of their movement along the deflection section 59 in the so-called return section 60 which extends approximately transversely to the aforementioned plane and allows the return of the retaining pin 56 in its rest position. About the transversely to the insertion direction Z extending guide surface portions of the guide groove 55 in the return section 60, a Bewegungsendanschlag is defined, which limits the insertion of the base 15 in the socket 14. When inserting the base 15 in the socket 14 of the assembly dome displaces the in FIG. 10 illustrated pressure plate 68 against the coil spring 69 also in the insertion direction Z, wherein the coil spring 69 a the insertion direction Z opposing spring tension builds up.

The guide groove 55 is approximately roof-shaped in the region of the return section 60, the ridge being directed into the socket recess 64. When the locking lug 67 reaches the movement end stop formed by the return section 60, the base 15 is released. Due to the roof-like design guide groove 55 in the return section 60 in cooperation with the locking tab 67 in the rest position moving spring tension, the locking tab 67 slides in the direction of ridge line, with a minimal return displacement of the base 15th opposite to the insertion direction Z is caused by spring-loaded pressure plate 68. If the locking nose 67 reaches the ridge area, the return movement of the retaining pin 56 is terminated for the time being. A residual spring tension remains the retaining pin 56, however. The locking tab 67 is seated in the locking portion 61 (the ridge) of the guide groove 55 and holds the base 15 against gravity direction in the socket 14. The base 15 is mechanically anchored in the socket 14 (see FIGS. 13a and 13b ). At the same time there is an electrical connection between the socket contacts and the socket contacts 53rd

To release the base 15 from the socket 14, the base 15 is again moved in the insertion direction Z. In this case, the locking tab 67 slides out of the locking portion 61 and in the direction of rest position of the retaining pin 56 until it reaches the Ausführabschnitt 62 of the guide groove 55. The transition from the return portion 60, which contains the locking portion 61, in the Ausführabschnitt 62 is located shortly before the point at which the locking tab 67 is located in the rest position of the retaining pin 56. The Ausführabschnitt 62 itself in turn encloses an angle with the above-defined lamp longitudinal axial plane, but is directed in the insertion direction Z of this pioneering.

The transition of the locking tab 67 in the Ausführabschnitt 62 is in Fig. 13c shown. At the same time, the return section 60 in the transition area into the Ausführabschnitt 62 by the guide surfaces of the guide groove 55 in turn forms a Bewegungsendanschlag, which prevents further insertion of the base 15 in the socket 14 into it.

After releasing the base 15, this now induced by the spring force of the coil spring 69, contrary to the insertion direction z slides out of the socket recess 64 until a removal position is reached. Due to the course of the Ausführabschnittes enforces this Exit movement in turn a spring return elastic deflection of the retaining pin 56, which is arranged in its rest position in the vertical plane (see above). The movement of the base 15 against the insertion direction Z when loosening from the socket 14 must therefore take place against the spring restoring force of the retaining pin 56, the thereby generated friction on the guide surfaces of the guide groove 55 brakes the movement. In an advantageous embodiment, the spring restoring force or induced by the Ausführabschnitt 62 deflection of the retaining pin 56 is dimensioned so that a return displacement of the base 15 from the socket 14 out against the insertion Z, for example, by gravity can be done only to a certain extent, without additional Force application by a user, however, this removal movement is not completed, so that the base 15 is held in the socket 14 in a removal position ( Fig. 14 ).

In this way it is prevented that in an accidental as intentional release of the base 15 from the socket 14, the lamp 11 uncontrollably leaves its mechanical anchoring and unintentional falling out of the lamp 11 from the lamp 10 is not possible. Only pulling out the base 15 from the socket 14 overcomes the frictional connection and forces the retaining pin 56 a deflection, via which it is adapted to leave the guide groove 55 via the outlet opening 63.

Finally, the assembly of the lamp 11 in the lamp 10 is now described, which uses both the method for inserting the holding part 13 in the holder 12 and the method for inserting the base 15 in the socket 14.

In this mounting method, first, the holding part 13 in front of the opening 26 in the region of the insertion portion 27 of the holder 12th positioned. The anchor head 38 is moved through the opening 26 in the insertion portion 27 in the insertion direction Y. The insertion direction Y is then transferred via the guide surfaces 30 in the insertion direction X. A further movement in the direction of insertion X of the anchor head 36 leads to its arrangement in the holding section 28. If present, the spring arm 41 of the einitzenden in the holding space 31 spring 40 is urged under construction of a spring tension from its rest position.

When inserting the holding member 13 in the holder 12, the lamp 11 has a lamp 10 inclined position (see Fig. 2 ), so that the base 15 is clearly spaced from the socket 14. Due to the possible by the shape of the end portions 39 of the anchor head 38 pivoting movement of the lamp 11, it is now possible zuzubewegen the base 14 in the insertion direction Z on the socket 14. The pivoting movement takes place around the anchor head 38, so that the insertion direction z is actually a circular movement and not a strictly linear movement. Due to the large radius, which is determined by the length of the lamp 11, the actual insertion movement Z of the mounting mandrel 51 into the socket recess 64 can be considered as a linear movement.

In continuation of the pivoting movement now passes the mounting dom 51 of the base 15 in the region of the insertion opening 66 of the socket housing 65 of the socket 14. He penetrates the insertion opening 66, wherein the locking tab 67 of the retaining pin 56 passes through the inlet opening 57 in the guide groove 55. It slides along the deflection section 59 while building up a spring tension along and is deflected spring return elastic. When the locking lug 67 arrives in the transition region from the deflection section 59 into the return section 60, the guide surfaces of the guide groove 55 form a movement end stop for a movement in the insertion direction Z.

The result of the movement of the mounting mandrel 51 into the socket recess 64 is that a pressure plate 68 which is spring-loaded in the socket recess 64 is also displaced in the insertion direction Z, building up a spring tension. When the locking tab 67 reaches the end of travel stop, the socket 15 is released by the user. The spring tension acts on the mounting mandrel 51 via the pressure plate 68 and leads to a partial rearward displacement against the insertion direction Z, wherein the retaining pin 56 moves along the guide groove in the return section 60 in the direction of its rest position. A roof-shaped portion of the return portion 60, which forms the actual locking portion 61, allows movement of the locking lug 67 up to a ridge. If this is reached, the return displacement of the mounting mandrel 51 induced by the pressure plate 68 also ends out of the socket 14. The locking tab 67, which rests in the locking portion 61 of the guide groove 55, now holds the base 15 against the spring-loaded pressure plate 68 and the possibly acting gravity in the socket 14. The base 15 is mechanically anchored in this way in the socket 14.

If the lamp 11 mounted in this way and held by the base 15 and the socket 14 on the one hand and by the holder 12 and the holding part 13 on the other hand, comes another advantage of the interaction of the holder 12 and holding part 13 to wear. When the lamp 11 is mounted, the anchor head 38 is mounted at a distance from the nearby second end wall 22 located at the rear in the insertion direction. Occurs now during operation of the lamp 11, the above-mentioned thermal expansion, the anchor head 38 in the holding section 28 correspondingly wander in the direction X, so that no damage to the lamp 11 or lamp 10 occur. The holder 12 and the holding part 13 thus allow the compensation of the thermal expansion of the lamp eleventh

To remove the lamp 11 from the lamp 10, the base 15 is now first again moved into the socket recess 64 in the insertion direction Z. This leads to a movement of the locking tab 67 in the direction of the rest position of the retaining pin 56, wherein the locking tab 67 leaves the return section 60 and in the Auslenkh section 59 opposite Ausführabschnitt 62 passes. This opens into an outlet opening 63 through which the locking tab 67 can leave the guide groove 55, so that a removal of the base 15 from the socket 14 is possible.

As described above, however, the Ausführabschnitt 62 of the locking tab 67 forces a movement, which in turn leads to a deflection of the retaining pin 56 and to build a spring tension. This spring tension is suitable for holding the mounting dome 51 against the spring tension of the pressure plate 68 and / or against any gravitational force in the socket 14, so that a failure of the socket 15 from the socket 14 is avoided (FIG. Fig. 14 ).

Now, an additional force is applied by the user, which dissolves the base 15 of the socket 14 and leads to a sliding out of the locking tab 67 of the guide groove 55. After this release of socket 15 and socket 14, the lamp 11 in turn has a light 10 inclined position (see Fig. 2 ).

Now, the anchor head 38 can be moved against the insertion direction X from the holding space 31 out into the insertion portion 27. The guide surfaces 30 reverse the direction of movement in a withdrawal direction which is opposite to the insertion direction Y. The anchor head 38 leaves the holder 12 through the opening 26, whereupon the mechanical connections between the lamp 11 and lamp 10 are canceled.

If a holder 12 with spring element 40 has found use, the spring arm 41 supports the movement against the insertion direction X and induces the disassembly movement. In addition, the spring arm 41 also pushes the anchor head 38 out of the holding space 31 and into the insertion section 27, when the lamp is inadvertently released from the socket 14 when the base 15 is released. In this way it is prevented that the forces exerted by such a dropping of the lamp and the resulting pivoting movement on the holder 12 and in particular their webs 29 destroy the latter. Even with such a malfunction is thus ensured that the holder 12 and thus the lamp remains intact.

As has been shown, the base 15 and the socket 12 serve the mechanical anchoring of the lamp 11 in the lamp 10 by a very advantageous operating concept, which is also known as a push-in push-out operating concept. This means that both for anchoring and for loosening the base 15 must be pressed into the socket 14. It is therefore obvious that, omitting socket contacts and base contacts and corresponding contact carrier components, it is possible to form a holding part and a holder which correspond to the base 15 and the socket 14 with regard to the components which are responsible for the mechanical anchoring. The use of such configured holder and holding part must therefore be regarded as equivalent to the use of socket and socket.

In addition, it is at any time apparent to those skilled in the art that the subject embodiment of the socket can be realized on the socket side and the objective embodiment of the socket can be realized on the front, without resulting in disadvantages or special design requirements. Even such a solution would therefore be considered equivalent.
