Description

The present invention relates to a cable securing device.
In the field of aeronautical engineering, a device like the one described in FIG. 1 for securing cables to a support is known.
This device comprises a base 10 with a first part 12 pressed firmly against a support 14 using connecting means 16 and a second part 18 in the shape of a C with an opening 20 to allow cables 22 to be inserted. The ends of the branches of the C comprise tabs 24 extending in an approximately radial direction and each having a slotted orifice 26.
First of all, the cables can be prepositioned by inserting them into the C shape. Advantageously, the interior wall of the C-shape has an elastomer coating 28 to protect the cables.
When the wiring is finished, the cables are held in the C-shape by a cable fastener 30 which passes through the two slots 26 and aims to bring the two tabs 24 closer together in order to clamp the cables 22.
To do this, the branches of the C are produced in such a way that they can deform elastically by selecting a suitable material and/or cross section. In addition, the elastomeric covering may contribute towards obtaining this elastic effect.
In a known way, a cable fastener 30, also known as a “tie-wrap”, firstly comprises a longilinear flat body with a plurality of notches perpendicular to its length on at least one face and, secondly, comprises a head connected to a first end and having a slotted orifice with a lug capable of engaging in one of the notches of the body so as to immobilize the body relative to the head.
To join the tabs 24 together the second end of the cable fastener has to be fed through the slots 26 in the tabs and through the slot in its head and this second end then has to be pulled.
One first disadvantage is that this type of securing device comprises a use-once part which means that the cable fasteners have to be cut and replaced if one or more cables is to be added, removed or changed.
A first objective of the invention is to provide a reusable and strong securing device.
To this end, the invention proposes a cable securing device comprising a base, a housing having an interior and an exterior surface and two spaced-apart edges allowing a plurality of cables to be inserted into the said housing, a central axis of the said cables defining a longitudinal direction, and a tongue connecting the two edges so as to hold the cables in the housing, the said tongue being connected removably at one end, known as the free end, to the first edge, characterized in that the tongue comprises at least one orifice capable of engaging with a pin provided on the exterior surface of the housing, and in that the interior surface of the tongue comprises a touch-and-close structure capable of engaging with a touch-and-close structure provided on the exterior surface of the housing.
The combination of connecting means of the touch-and-close type and of the pin/orifice type means that a strong removable connection can be achieved.
For preference, the housing comprises two pins positioned in a longitudinal direction and in that the tongue comprises at least two orifices, one for each pin.
which are provided on the tongue in order to improve strength.

Another object of the invention is to propose a cable securing device that is easy to use. To this end, the tongue is connected, at the opposite end to the free end, permanently to the second edge of the housing. Further features and advantages will become apparent from the description of the invention which follows, which description is given purely by way of example with reference to the attached drawings in which:

FIG. 1 is a side view of a cable securing device according to the prior art,

FIG. 2 is a side view of a cable securing device according to the invention,

FIG. 3 is a cross section illustrating in detail the removable connection of the securing device of the invention,

FIG. 4 is a view in perspective from a first direction of a cable securing device, and

FIG. 5 is a view in perspective from a different direction of a cable securing device.

According to one embodiment, a cable securing device comprises a base 32 with a first part 34 that can be pressed firmly against a support 36 using connecting means 38 and a second part defining a housing 40 in which the cables 42 can be positioned.
For the remainder of the description, a longitudinal direction means the direction of the cables.
A transverse plane means a plane perpendicular to the longitudinal direction.
Finally, a transverse direction means a direction perpendicular to the longitudinal direction and parallel to the support.
The first part 34 has shapes suited to the support 36.
In the case of a support that offers a substantially flat bearing surface, the first part 34 is in the form of a plate, for example a rectangular plate with rounded corners, with an underside surface resting against the substantially flat support 36.
However, other shapes of the first part 34 are conceivable.
The first part 34 comprises at least one orifice 44 allowing the passage of the connecting means 38.
The connecting means 38 may be in the form of a screw, of bolts (visible in FIG. 2), of rivets or of dowels (visible in FIGS. 4 and 5).
However, the invention is not restricted to these connecting means and likewise covers solutions involving bonding, welding or some other technique.
The second part defines a housing 40 and is in the form of a conduit directed in the longitudinal direction, with a slot that is wide enough to allow the cables to be inserted into the conduit, the said slot or opening being delimited by edges 46, 46′, which are preferably parallel to one another and directed in the longitudinal direction.
Depending on circumstance, the width of the slot may vary and the conduit may extend over a greater or smaller sector.
According to one embodiment, the conduit is connected to the first part 34 in such a way as to create two branches extending from the first part 34, the ends of the branches constituting the edges 46, 46′.
Advantageously, the spacing between the branches narrows at the edges 46, 46′, so as to retain the cables 42.
According to the embodiment illustrated in FIGS. 2 to 5, the housing 40 is C-shaped.
For preference, the branches have cross sections (in transverse planes) that are substantially constant.
The split conduit housing 40 has a width (in the longitudinal direction) of the order of 0.5 cm to 5 cm in order to provide satisfactory guidance for the cables 42.
According to a preferred embodiment, the first part 34 and the housing 40 are made as a single piece by being moulded in plastic.
The thickness and/or the material of the split conduit are suitable for it being able to deform slightly in an elastic manner so as to increase the cross section for the passage of the cables and thus adapt to suit a range of diameters of cable wiring harness 42.
For preference, the interior face of the split conduit facing towards the cables has a coating 48 aimed at protecting the cables. By way of example, this coating 48 is made of elastomer.
According to the invention, in order to hold the cables in position, the device comprises a tongue 50 permanently connected to one of the edges 46 of the conduit and removably connected to the other edge 46′ of the conduit.
This tongue 50 is flexible enough that it can initially uncover the space between the edges 46, 46′ to allow the cables to be inserted and can then connect the edges 46, 46′.
This tongue 50 preferably has a width substantially identical to that of the split conduit.
In a first alternative form, the tongue 50 is separate from the split conduit. In such a case, one of the ends of the tongue 50 is secured by any suitable permanent means to one of the edges 46 of the conduit, for example by bonding.
According to another alternative, the tongue 50 is made as a single piece with the split conduit. In such a case, the tongue 50 has a thickness appreciably smaller than that of the split conduit in order to give it its flexibility.
In order to obtain a removable connection, the free end of the tongue 50 comprises at least one orifice 52 capable of engaging with a pin 54 provided on the exterior surface of the conduit near the edge 46′, the surface of the said free end of the tongue that faces towards the split conduit comprising a touch-and-close structure 56 capable of engaging with a touch-and-close structure 56′ provided on the exterior surface of the conduit near the edge 46′.
This configuration makes it possible to obtain a securing device that is strong and reusable.
For preference, the exterior surface of the conduit comprises two pins 54 positioned in a longitudinal direction. To complement these, the tongue 50 comprises at least two orifices 52, one for each pin.
This configuration makes it possible to prevent the tongue 50 from pivoting with respect to the edge 46′, thus improving the pull-out strength of the removable connection between the tongue 50 and the edge 46′.
Advantageously, the tongue 50 comprises at least one series of orifices 52, one series for each pin 54, the orifices of one and the same series being positioned in a transverse plane and preferably uniformly spaced.
This configuration allows the securing device to be adapted to suit various diameters of cable wiring harness 42.
According to one embodiment, the touch-and- close structures 56 and 56′ are touch-and-close structures of the “velcro®” type, the touch-and-close structure 56 comprising loops and the touch-and-close structure 56′ comprising hooks.
To provide a better strength, the touch-and-close structure 56′ is positioned around each pin 54 while the touch-and-close structure 56 is positioned around each orifice 52.
According to one preferred embodiment, the touch-and-close structure 56 is a strip with loops that is independent of the tongue 50 and secured to the interior surface of the tongue for example by bonding. In parallel, the touch-and-close structure 56′ may be incorporated into the branch 46′, the hooks of the said structure 56′ being produced at the time of moulding of the base.
