Definitions
- the invention relates to a plug connection for rear wall wiring, consisting of a male connector designed as a rectangular housing that is open on one side and a female connector that can be inserted therein.
- the female connector Since the female connector should not have any play after being inserted into the male connector, its outer dimensions correspond to the inner dimensions of the male connector. This results in problems when inserting the female connector into the male connector, since the female connector must hit the opening of the male connector exactly during the plugging process.
- the plug-in process is particularly difficult for plug-in connections for backplane wiring in which the female connectors are attached to the end of printed circuit boards. In most cases, the plug connection is no longer visible here and is no longer accessible for additional manual support.
- the object of the present invention is to provide a plug-in connection for backplane wiring of the type mentioned at the beginning, in which the plugging-in process is made considerably easier.
- the so-called catch area is enlarged in the end areas. This means that when the female connector is plugged in, there is a quick lateral guide at the ends with an enlarged mounting width. When the female connector subsequently enters the actual male connector body during the plug-in process, an exact lateral guidance of the female connector is then ensured. This side guide is particularly important because the female connector is relatively narrow compared to its length. The plug connection according to the invention thus enables a problem-free plug-in process.
- An expedient development of the plug connection according to the invention is characterized in that the end walls of the male connector are formed at least on one side as high as the raised end regions of the longitudinal walls. This results in an additional guide in the longitudinal direction of the female connector.
- the raised end regions of the longitudinal walls 6 of the male connector 1 are designated by the reference number 3 in FIG. 1. These raised end regions of the two longitudinal walls have bevels 4 running inwards. Accordingly, the longitudinal edges of the female connector 2 have bevels 9 in their respective end regions. The length of the bevels 9 corresponds to the length of the raised end regions 3 of the longitudinal walls 6 of the male connector.
- the bevels 9 of the female connector 2 first meet the raised end regions 3 of the longitudinal walls 6 of the male connector during the plugging process. Due to the additional bevels on the female connector, the catch area between male connector 1 and female connector 2 is in the Endbe range significantly enlarged compared to the other areas. This results in a demonstration with a greater tolerance, since the width of the receptacle is increased at the ends. This considerably facilitates the insertion of the female connector 2 into the male connector 1. When the female connector 2 actually enters the actual strip body of the male connector 1 during the plugging process, exact lateral guidance of the female connector 2 within the male connector 1 is then ensured.
- An additional guide in the longitudinal direction of the female connector 2 can be achieved in that the end walls 7 of the male connector 1 are each formed at least on one side as high as the raised end regions of the longitudinal walls 6.

Abstract
Description
Die Erfindung betrifft eine Steckverbindung für Rückwandverdrahtungen, bestehend aus einer als einseitig offenes rechtwinkliges Gehäuse ausgebildeten Messerleiste und einer darin einsteckbaren Federleiste.The invention relates to a plug connection for rear wall wiring, consisting of a male connector designed as a rectangular housing that is open on one side and a female connector that can be inserted therein.
Da die Federleiste nach dem Einstecken in die Messerleiste kein Spiel aufweisen soll, entsprechen ihre Aussenabmessungen den Innenabmessungen der Messerleiste. Dadurch ergeben sich Probleme beim Einstecken der Federleiste in die Messerleiste, da die Federleiste beim Steckvorgang genau auf die Öffnung der Messerleiste treffen muß. Besonders schwierig gestaltet sich der Steckvorgang bei Steckverbindungen für Rückwandverdrahtungen, bei denen die Federleisten am Ende von Leiterplatten angebracht sind. Hier ist die Steckverbindung in den meisten Fällen nicht mehr einsehbar und für eine zusätzliche manuelle Unterstützung auch nicht mehr erreichbar.Since the female connector should not have any play after being inserted into the male connector, its outer dimensions correspond to the inner dimensions of the male connector. This results in problems when inserting the female connector into the male connector, since the female connector must hit the opening of the male connector exactly during the plugging process. The plug-in process is particularly difficult for plug-in connections for backplane wiring in which the female connectors are attached to the end of printed circuit boards. In most cases, the plug connection is no longer visible here and is no longer accessible for additional manual support.
Aufgabe der vorliegenden Erfindung ist es, eine Steckverbindung für Rückwandverdrahtungen der eingangs genannten Art anzugeben, bei welcher der Einsteckvorgang wesentlich erleichtert wird.The object of the present invention is to provide a plug-in connection for backplane wiring of the type mentioned at the beginning, in which the plugging-in process is made considerably easier.
Diese Aufgabe wird für eine Steckverbindung der obengenannten Art dadurch gelöst, daß die Längswände der Messerleiste in ihren beiden Endbereichen erhöht sind und mit einer nach ihnen laufenden Schräge versehen sind, und daß die Längskanten der Federleiste in ihren beiden Endbereichen abgeschrägt sind, wobei die Längen der Abschrägungen der Federleiste der Längen der erhöhten Endbereiche der Längswände der Messerleiste entsprechen.This object is achieved for a plug connection of the type mentioned above in that the longitudinal walls of the male connector are raised in their two end regions and are provided with a slope running after them, and in that the longitudinal edges of the female connector in their both end areas are bevelled, the lengths of the bevels of the female connector corresponding to the lengths of the raised end areas of the longitudinal walls of the male connector.
Aufgrund der erhöhten abgeschrägten Endbereiche der Längswände der Messerleiste in Verbindung mit den entsprechenden Abschrägungen der Längskanten der Federleiste wird in den Endbereichen der sogenannte Fangbereich vergrößert. Das bedeutet, es ergibt sich beim Stecken der Federleiste ziemlich schnell eine seitliche Führung an den Enden mit einer vergrößerten Aufnahmebreite. Bei dem danach erfolgenden Eintreten der Federleiste in den eigentlichen Messerleistenkörper während des Steckvorgangs ist dann eine exakte Seitenführung der Federleiste gewährleistet. Diese Seitenführung ist besonders wichtig, da die Federleiste verglichen mit ihrer Länge verhältnismäßig schmal ist. Die erfindungsgemäße Steckverbindung ermöglicht also einen problemlosen Steckvorgang.Due to the increased beveled end areas of the longitudinal walls of the male connector in conjunction with the corresponding bevels of the longitudinal edges of the female connector, the so-called catch area is enlarged in the end areas. This means that when the female connector is plugged in, there is a quick lateral guide at the ends with an enlarged mounting width. When the female connector subsequently enters the actual male connector body during the plug-in process, an exact lateral guidance of the female connector is then ensured. This side guide is particularly important because the female connector is relatively narrow compared to its length. The plug connection according to the invention thus enables a problem-free plug-in process.
Eine zweckmäßige Weiterbildung der erfindungsgemäßen Steckverbindung ist dadurch gekennzeichnet, daß die Stirnwände der Messerleiste zumindest an einer Seite so hoch wie die erhöhten Endbereiche der Längswände ausgebildet sind. Dadurch ergibt sich eine zusätzliche Führung in Längsrichtung der Federleiste.An expedient development of the plug connection according to the invention is characterized in that the end walls of the male connector are formed at least on one side as high as the raised end regions of the longitudinal walls. This results in an additional guide in the longitudinal direction of the female connector.
Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing.
Es zeigen
- Fig. 1 eine teilweise perspektivische Ansicht einer Messerleiste und
- Fig. 2 eine teilweise perspektivische Ansicht einer Federleiste gemäß der vorliegenden Erfindung.
- Fig. 1 zeigt ein Ende einer Messerleiste 1 mit
Kontaktmessern 5. In der Figur sind von vielen möglichen Kontaktmessern lediglich dreiKontaktmesser 5 dargestellt. - Fig. 2 zeigt eine Draufsicht auf ein Ende einer
Federleiste 2 mit denEinstecköffnungen 8 für die Kontaktmesser. Im dargestellten Ausführungsbeispiel ist davon ausgegangen, daß die Messerleiste 1 drei Reihen vonKontaktmessern 5 aufweist, und dementsprechend die Federleiste drei Reihen vonEinstecköffnungen 8 für dieKontaktmesser 5. Ebenso denkbar wäre allerdings, daß dieerfindungsgemäße Steckverbindung 5 oder mehr Reihen vonKontaktmessern 5 aufweist.
- Fig. 1 is a partial perspective view of a Knife rack and
- Fig. 2 is a partial perspective view of a female connector according to the present invention.
- 1 shows one end of a male connector 1 with
contact blades 5. Only threecontact blades 5 of many possible contact blades are shown in the figure. - Fig. 2 shows a plan view of one end of a
female connector 2 with theinsertion openings 8 for the contact knife. In the illustrated embodiment, it is assumed that the male connector 1 has three rows ofcontact blades 5, and accordingly the female connector has three rows ofinsertion openings 8 for thecontact blades 5. However, it would also be conceivable that the connector according to the invention has 5 or more rows ofcontact blades 5.
Die erhöhten Endbereiche der Längswände 6 der Messerleiste 1 sind in Fig. 1 mit der Bezugsziffer 3 bezeichnet. Diese erhöhten Endbereiche der beiden Längswände weisen nach innenverlaufende Abschrägungen 4 auf. Dementsprechend weisen die Längskanten der Federleiste 2 in ihren jeweiligen Endbereichen Abschrägungen 9 auf. Die Länge der Abschrägungen 9 entspricht der Länge der erhöhten Endbereiche 3 der Längswände 6 der Messerleiste.The raised end regions of the
Anhand der Figuren ist deutlich zu erkennen, daß beim Steckvorgang zuerst die Abschrägungen 9 der Federleiste 2 auf die erhöhten Endbereiche 3 der Längswände 6 der Messerleiste treffen. Durch die zusätzlichen Abschrägungen an der Federleiste wird der Fangbereich zwischen Messerleiste 1 und Federleiste 2 in den Endbereichen gegenüber den übrigen Bereichen erheblich vergrößert. Es ergibt sich somit eine Vorführung mit einer größeren Toleranz, da die Aufnahmebreite an den Enden vergrößert ist. Dadurch wird das Einführen der Federleiste 2 in die Messerleiste 1 erheblich erleichtert. Beim eigentlichen Eintreten der Federleiste 2 in den eigentlichen Leistenkörper der Messerleiste 1 während des Steckvorgangs ist dann eine exakte Seitenführung der Federleiste 2 innerhalb der Messerleiste 1 gewährleistet.On the basis of the figures it can be clearly seen that the
Eine zusätzliche Führung in Längsrichtung der Federleiste 2 kann dadurch erreicht werden, daß die Stirnwände 7 der Messerleiste 1 zumindest an einer Seite jeweils so hoch wie die erhöhten Endbereiche der Längswände 6 ausgebildet sind.An additional guide in the longitudinal direction of the
