Description

Die Anmeldung betrifft eine Vorrichtung zur Herstellung von lösbaren elektrischen Verbindungen zwischen in Gestellen einsteckbaren, spritzgegossenen Leiterplatten und den in den Gestellen angeordneten Rückwandverdrahtungen über aus Kontaktstücken bestehende Steckverbinder.The application relates to a device for manufacturing of detachable electrical connections between in Rack insertable, injection molded circuit boards and those arranged in the racks Backplane wiring over from contact pieces existing connectors.

Spritzgegossene Leiterplatten sind bekannt (Aufsatz: "Thermoplast zum Herstellen dreidimensionaler Leiterplatten" in ELEKTRONIK PRODUKTION & PRÜFTECHNIK, Dezember 1986, Seiten 16 und 17). Um derartige Leiterplatten für die Kontaktgabe zu Rückwandverdrahtungen in Gestellen geeignet zu machen, werden diskrete Steckverbinder-Leisten verwendet, welche an einer Kante der Leiterplatte befestigt und mit Leiterbahnen auf der Leiterplatte elektrisch leitend verbunden werden. Injection molded circuit boards are known (article: "Thermoplastic for making three-dimensional PCB "in ELECTRONICS PRODUCTION & TEST TECHNOLOGY, December 1986, pages 16 and 17). To such Printed circuit boards for making contact Make backplane wiring suitable in racks, discrete connector strips are used, which is attached to an edge of the circuit board and with conductor tracks on the circuit board electrically be conductively connected.  

Diese bekannte Vorrichtung ist beispielsweise in der Herstellung und der Montage aufwendig. Außerdem ist für die Kontaktoberflächen wegen ihrer Belastung beim Ziehen und Stecken der Leiterplatten ein großer Aufwand erforderlich.This known device is for example in the Manufacturing and assembly complex. Also is for the contact surfaces because of their stress when Pulling and inserting the circuit boards is a big effort required.

Das der Erfindung zugrunde liegende technische Problem besteht deshalb darin, die lösbare elektrische Verbindung zwischen Leiterplatte und Rückwandverdrahtung zu verbessern.The technical problem underlying the invention is therefore the releasable electrical Connection between circuit board and Improve backplane wiring.

Dieses technische Problem ist erfindungsgemäß dadurch gelöst, daß die Kontaktstücke einstückig in die spritzgegossene Leiterplatte mit eingespritzt sind.This technical problem is according to the invention solved that the contact pieces in one piece in the injection molded printed circuit board are also injected.

Bei der erfindungsgemäßen Vorrichtung entfallen die diskreten Steckverbinder, wodurch der Aufwand beim Material und bei der Montage verringert wird. Es lassen sich mechanisch geringer belastete Kontaktflächen verwirklichen. Außerdem lassen sich für die Befestigung und die Positionierung benötigte Teile ebenfalls einstückig mit anspritzen und es wird sogar noch Einbauvolumen eingespart.In the device according to the invention, the discrete connector, reducing the effort in Material and assembly is reduced. Leave it contact surfaces exposed to less mechanical stress realize. They can also be used for attachment and the positioning needed parts too in one piece with inject and it will even Installation volume saved.

Die Erfindung ist nachstehend anhand der Fig. 1 bis 5 näher erläutert. Es zeigen:The invention is explained in more detail below with reference to FIGS. 1 to 5. Show it:

Fig. 1 einen Ausschnitt der Seitenansicht einer in ein Gestell eingeschobenen Leiterplatte, Fig. 1 shows a detail of the side view of a frame inserted in a printed circuit board,

Fig. 2 den Ausschnitt aus Gestell und Leiterplatte in einer Draufsicht entsprechend dem Pfeil A in Fig. 1, Fig. 2 shows the detail of the frame and circuit board in a top view according to the arrow A in Fig. 1,

Fig. 3 einen einstückig an die Leiterplatte angespritzten Federhaken, Fig. 3 is an integrally molded to the circuit board spring hook,

Fig. 4 eine einstückig an die Leiterplatte angespritzte Kontaktfeder, und Fig. 4 is an integrally molded on the circuit board contact spring, and

Fig. 5 die Draufsicht auf mehrere nebeneinander angeordnete Kontaktfedern. Fig. 5 is a plan view of a plurality of contact springs arranged side by side.

Aus Fig. 1 ist ein Teil eines Gestells zu erkennen, welches aus der Horizontalschiene 1 und der an dieser befestigten Rückwandverdrahtung 2 besteht, bei der es sich ebenfalls um eine Leiterplatte handeln kann. Wie aus Fig. 2 besser zu erkennen, ist an der Horizontalschiene 1 eine U-förmige Führung 3 für die Leiterplatte 4 befestigt. Die Führung 3 ist mittels des an ihr angespritzten Fixierzapfens 5 in der Rückwandverdrahtung 2 fixiert. Die Leiterplatte 4 ist an ihrer der Rückwandverdrahtung zugewandten Kante mit einer Mehrzahl von Kontaktfedern 6 versehen, welche einstückig an der Leiterplatte 4 angespritzt sind. Die Leiterplatte 4 ist mittels des ebenfalls einstückig an ihr angespritzten Führungsstiftes 7 fixiert und durch die ebenfalls einstückig an der Leiterplatte 4 angespritzte Federhaken 8 in der Rückwandverdrahtung 2 befestigt.From Fig. 1 a part of a frame can be seen, which consists of the horizontal rail 1 and the attached to this rear wall wiring 2 , which can also be a circuit board. As can be seen better from FIG. 2, a U-shaped guide 3 for the printed circuit board 4 is fastened to the horizontal rail 1 . The guide 3 is fixed in the rear wall wiring 2 by means of the fixing pin 5 molded onto it. The circuit board 4 is provided on its edge facing the rear wall wiring with a plurality of contact springs 6 , which are integrally molded onto the circuit board 4 . The printed circuit board 4 is fixed by means of the guide pin 7, which is also integrally molded onto it, and is fastened in the rear wall wiring 2 by the spring hooks 8 also molded integrally on the printed circuit board 4 .

Fig. 3 verdeutlicht die Ausbildung des Federhakens 8, welcher die Rückwandverdrahtung 2 durchstößt und mittels einer Nase auf ihrer Rückseite einrastet. Fig. 3 illustrates the design of the spring hook 8 , which pierces the rear wall wiring 2 and snaps into place on the back by means of a nose.

Fig. 4 zeigt ein Ausführungsbeispiel der an der Leiterplatte 4 einstückig angespritzten Kontaktfeder 6. Das Ende der Kontaktfeder 6 ist mit einer Verdickung versehen, welche federnd auf einer Kontaktfläche auf der Rückwandverdrahtung 2 aufliegt. Fig. 4 shows an embodiment of the integrally molded to the circuit board 4 Contact spring 6. The end of the contact spring 6 is provided with a thickening which rests resiliently on a contact surface on the rear wall wiring 2 .

Fig. 5 verdeutlicht eine zweireihige Anordnung der Kontaktflächen 9 auf der Rückwandverdrahtung 2. Es läßt sich dadurch eine dichtgedrängte Anordnung der Kontakte verwirklichen, wenn längere und kürzere Kontaktfedern 6 einander abwechseln. Fig. 5 illustrates a two-row arrangement of the contact surfaces 9 on the backplane wiring 2. This allows a tightly packed arrangement of the contacts to be achieved if longer and shorter contact springs 6 alternate with one another.
