Die Erfindung liegt auf dem Gebiet des Lösens einer Rastverbindung zwischen einem Modul und einer ein Rastelement aufweisenden Halterung.The invention is in the field of releasing a locking connection between a module and a holder having a locking element.
Bei Verwendung von Modulen, beispielsweise., elektrooptischen Modulen (sogenannte Tranceiver), die mittels einer Rastverbindung mit einer auf einem Träger, beispielsweise einer Leiterplatte, angeordneten Halterung verbunden sind ist es für den Anwender wünschenswert, dass die Module auf einfache Weise aus der Halterung demontiert werden können.When using modules, for example electro-optical modules (so-called transceivers), which are connected by means of a snap-in connection to a holder arranged on a carrier, for example a printed circuit board, it is desirable for the user that the modules be removed from the holder in a simple manner can be.
Um auf mit Leitbahnen und Anschlusskontakten versehenen Leiterplatten elektrooptische Module frei und uneingeschränkt platzieren zu können, werden anwenderseitig zunehmend Modul- bauformen und geeignete mechanische Verbindungen erforder- lieh, die mittels einer Führung der auf der Leiterplatte angeordneten Halterung ein einfaches Einschieben und Herausziehen des Moduls längs der Halterung und eine ausreichend zugfeste mechanische Fixierung mittels eines an der Halterung ausgebildeten, in eine Öffnung des Modulgehäuses eingreifen- den Rastelements zulassen. Hierbei sollte das zur Aufnahme eines Steckverbinders zumindest einseitig offen ausgebildete Gehäuse des Moduls zum Einführen des Steckverbinders gut zugänglich sein (ähnlich US-PS 5,980,324 A und DE-Anmeldung 198 436 27.0) .In order to be able to place electro-optical modules freely and unrestrictedly on printed circuit boards provided with conductor tracks and connection contacts, module designs and suitable mechanical connections are increasingly required on the part of the user, which means that the module arranged on the printed circuit board can be easily inserted and removed along the Allow bracket and a sufficiently tensile mechanical fixation by means of a locking element formed on the bracket and engaging in an opening of the module housing. The housing of the module for inserting the connector, which is at least open on one side for receiving a connector, should be easily accessible (similar to US Pat. No. 5,980,324 A and DE application 198 436 27.0).
Aufgabe der Erfindung ist es, ein Werkzeug zu schaffen, mit dem eine solche Rastverbindung auf einfache Weise gelöst werden kan . Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, dass das Werkzeug aus einem quaderformigen, auf einer Teillänge in das Gehäuse des Moduls einführbaren Körper besteht, der in- nerhalb seines Umrisses einen von Hand zu betätigenden, federnd angeordneten Zapfen zum Entriegeln des Rastelements aufweist .The object of the invention is to provide a tool with which such a locking connection can be solved in a simple manner. According to the invention, this object is achieved in that the tool consists of a cuboid body, which can be inserted over a partial length into the housing of the module and which has, within its outline, a manually operated, spring-mounted pin for unlocking the latching element.
Bei Verwendung eines derartig ausgestalteten Werkzeugs bedarf es zur Demontage des Moduls keiner Zugänglichkeit zum Modul- gehäuses von außen, so dass das Modulgehäuse in einem Auf ah- megestell so angeordnet sein kann, dass es mit der zur Aufnahme des Steckverbinders offen ausgebildeten Seite bündig mit einer Wand des Aufnahmegesteils abschließt und somit si- eher vor seitlich einwirkenden Kräften und mechanischen Stößen' geschützt ist.When using a tool designed in this way, there is no need to access the module housing from the outside to disassemble the module, so that the module housing can be arranged in a mounting frame in such a way that it is flush with one side with the side designed to receive the connector Closes the wall of the receiving part and is therefore more protected from lateral forces and mechanical shocks.
Eine fertigungstechnisch bevorzugte Ausgestaltung des neuen Werkzeuges besteht darin, dass der federnd angeordnete Zapfen einstückig mit dem quaderformigen Körper ausgebildet ist.A preferred embodiment of the new tool in terms of production technology is that the resiliently arranged pin is formed in one piece with the cuboid body.
Eine besonders anwenderfreundliche Gestaltung des neuen Werkzeuges ist nach einer bevorzugten Weiterbildung der Erfindung dadurch realisiert, dass der Körper einen spaltartigen Hohl- räum aufweist, in dem nach Art einer Biegefeder ein Federelement angeordnet ist, dessen bewegliches Ende den Zapfen bildet.A particularly user-friendly design of the new tool is realized according to a preferred development of the invention in that the body has a gap-like cavity in which a spring element is arranged in the manner of a spiral spring, the movable end of which forms the pin.
Ein Ausführungsbeispiel der Erfindung ist in den Figuren 1 und 2 der Zeichnung dargestellt. Dabei zeigenAn embodiment of the invention is shown in Figures 1 and 2 of the drawing. Show
Figur 1 ein Werkzeug in perspektivischer Darstellung und Figur 2 eine Schnittdarstellung des Werkzeugs gemäß Figur 1. Das Werkzeug gemäß der Figur 1 bildet einen quaderformigen, einstückigen Körper 1. Der Körper 1 besteht aus einem spritztechnisch verarbeiteten Kunststoff, kann aber auch aus einem anderen Material bestehen. Der Körper 1 weist an seinem einen Ende 2 Führungsschrägen 3 auf, die ein Einführen des Körpers auf einer Teillänge Ll in ein zur Aufnahme eines Steckverbinders zumindest einseitig offen ausgebildetes Modulgehäuse (in der Zeichnung nicht dargestellt) erleichtern. Der Körper 1 wird hierbei anstelle eines Steckverbinders in das Modulge- häuse eingeführt und ist an dem ersten Ende 2 an die innenseitige Ausgestaltung des Moduls derart angepasst, dass beim Einführen des Körpers bis in seine Endpositio im Modulgehäuse angeordnete, elektrische oder elektrooptische Bestandteile des Moduls nicht beschädigt werden. Der Körper 1 weist einen spaltartigen Hohlraum 4 auf, in dem nach Art einer Biegefeder ein Federelement 5 angeordnet ist, das als integraler Bestandteil des Körpers 1 ausgebildet ist.1 shows a tool in perspective and FIG. 2 shows a sectional view of the tool according to FIG. 1. The tool according to FIG. 1 forms a cuboid-shaped, one-piece body 1. The body 1 is made of a plastic processed by injection molding, but can also consist of another material. The body 1 has at its one end 2 guide bevels 3 which facilitate insertion of the body over a partial length L1 into a module housing (not shown in the drawing) which is open at least on one side for receiving a connector. The body 1 is inserted into the module housing instead of a plug connector and is adapted at the first end 2 to the inside configuration of the module in such a way that when the body is inserted into its end position in the module housing, electrical or electro-optical components of the module are not to be damaged. The body 1 has a gap-like cavity 4, in which a spring element 5 is arranged in the manner of a spiral spring and is formed as an integral part of the body 1.
Gemäß Figur 2 ist das bewegliche Ende des Federelementes 5 als ein zylindrischer Zapfen 6 ausgebildet, der sich im Bereich der Teillänge Ll sowie in der Ruheposition des Federelementes innerhalb des Umrisses des quaderformigen Körpers befindet. Eine derartige Ausgestaltung des Federelementes 5 ermöglicht es, den Körper 1 ohne Behinderung durch den Zapfen 6 in das Modulgehäuse einzuführen. Der übrige Teil des' Federelementes 5, der sich ebenfalls innerhalb des Umrisses des quaderformigen Körpers befindet verläuft im Bereich der Teillänge L2 des Körpers 1, der - bei bis in seine Endposition eingestecktem Körper - aus dem Modulgehäuse herausragt. Im Bereich dieser Teillänge L2 kann auf das Federelement 5 eine Kraft ausgeübt werden, so dass der Zapfen 6 senkrecht zur Steckrichtung A über den quaderformigen Umriss des Körpers 1 hinausbewegt wird. Der Körper 1 weist hierzu an der dem Zap- fen 6 angewandten Seite eine Mulde 7 auf, deren Boden 8 durch den spaltartigen Hohlraum 4 geteilt ist. Ein Abschnitt 9 des Federelementes 5 ragt durch den spaltenartigen Hohlraum 4 über den Boden 8 der Mulde 7 hinaus. Von Hand kann dieser Ab- schnitt 9 des Federelementes bis zum Boden 8 der Mulde 7 heruntergedrückt werden. Der Zapfen 6 wirkt auf ein in einer Öffnung der Gehäusewand des Moduls eingerastetes Rastelement, das an einer Halterung für das Modul ausgebildet ist . Dabei durchdringt der Zapfen 6 die Öffnung der Gehäusewand des Mo- duls, so dass das Modul bei eingedrücktem Federelement 5 durch Ziehen am Werkzeug entgegen der Steckrichtung A gemeinsam mit dem Werkzeug aus der Halterung herausgezogen werden kann (in der Zeichnung nicht weiter dargestellt) . Hierbei können hohe Reibungskräfte, die zur sicheren Positionierung des Moduls zwischen der Halterung und dem Modul wirken, überwunden werden.According to Figure 2, the movable end of the spring element 5 is designed as a cylindrical pin 6 which is located in the area of the partial length L1 and in the rest position of the spring element within the outline of the cuboid body. Such a configuration of the spring element 5 enables the body 1 to be inserted into the module housing without obstruction by the pin 6. The remaining part of the 'spring element 5, which is also located within the outline of the cuboid body, extends in the region of the partial length L2 of the body 1, which - with the body inserted into its end position - protrudes from the module housing. In the area of this partial length L2, a force can be exerted on the spring element 5, so that the pin 6 is moved perpendicular to the insertion direction A beyond the cuboidal outline of the body 1. For this purpose, the body 1 points at the fen 6 applied side a trough 7, the bottom 8 is divided by the gap-like cavity 4. A section 9 of the spring element 5 protrudes through the column-like cavity 4 beyond the bottom 8 of the trough 7. This section 9 of the spring element can be pressed down to the bottom 8 of the trough 7 by hand. The pin 6 acts on a latching element which is latched into an opening in the housing wall of the module and is formed on a holder for the module. The pin 6 penetrates the opening of the housing wall of the module, so that the module can be pulled out of the holder together with the tool when the spring element 5 is pressed in by pulling the tool against the plug direction A (not shown in the drawing). In this way, high frictional forces, which act to securely position the module between the holder and the module, can be overcome.
Weil bei der Verwendung des neuen Werkzeuges ein für Demontagezwecke bisher erforderlicher seitlicher Zugangsraum nicht erforderlich ist werden Anordnungen realisierbar, die sich durch eine hohe Packungsdichte der Module auszeichnen. Because when using the new tool, a lateral access space previously required for disassembly purposes is not required, arrangements can be realized which are characterized by a high packing density of the modules.
