Description

Die Erfindung betrifft einen elektrischen Kabelsteckverbinder mit in Kammern eines Kunststoffgehäuses in einer Reihe angeordneten Kontaktelementen, die - in Längsrichtung gesehen - jeweils auf ihrer einen Seite einen ersten Anschlußabschnitt, insbesondere Schneidklemmkontakte zum abisolierfreien Anschluß eines Kabels, und an ihrer gegenüberliegenden Seite einen zweiten Anschlußabschnitt, insbesondere ein Federzungenpaar zum Anschluß eines Steckerkontaktstiftes, aufweisen, wobei eine Kurzschlußüberbrückung zwischen zwei Kontaktelementen vorgesehen ist.The invention relates to an electrical cable connector with in chambers a plastic housing arranged in a row contact elements, which - in Seen in the longitudinal direction - a first on each side Connection section, in particular insulation displacement contacts for stripping-free Connect one cable and a second on the opposite side Connection section, in particular a pair of spring tongues for connecting a Have plug contact pin, with a short-circuit bridging between two contact elements is provided.

Ein solcher elektrischer Kabelsteckverbinder ist aus der DE-OS 38 04 950 bekannt. Dabei sind elektrische Kontaktelemente in einer Reihe in einem Kunststoffgehäuse angeordnet und als Blattfederkontakte ausgebildet, wobei die entsprechenden Leiterbahnen in Schneidklemmtechnik mit den jeweiligen Kontaktfedern kontaktiert werden. Ein solcher Steckverbinder kann beispielsweise auf den Rand einer Leiterplatte aufgesteckt werden, um so die elektrische Verbindung mittels der Leiterbahnen zu den auf der Leiterplatte angeordneten elektronischen Bauteilen herstellen zu können. Es ist aber auch möglich, den Steckverbinder auf eine spezielle Stiftleiste aufzustecken. In verschiedenen Anwendungsfällen ist es wünschenswert, bei einem derartigen Steckverbinder zwei oder mehrere elektrische Kontaktelemente mit einer Kurzschlußüberbrückung zu versehen. Dabei kann es erforderlich sein, entweder unmittelbar benachbarte elektrische Kontaktelemente zu überbrücken, oder aber auch beliebige elektrische Kontaktelemente innerhalb der Reihe zu überbrücken, so daß einzelne elektrische Kontaktelemente übersprungen werden. Hierzu ist es bekannt, ein im wesentlichen U-förmiges, elektrisch leitendes Überbrückungselement zu verwenden, welches mit seinen beiden Schenkeln jeweils mit diesen auf die elektrischen Kontaktelemente von oben aufsteckbar ist und nach dem Aufstecken mit diesen in elektrischem Kontakt steht. Nachteiligerweise greifen dabei die Schenkel des Überbrückungselementes in die Schlitze der erfaßten Schneidklemmkontaktelemente ein und verschließen diese praktisch in vollem Umfange. Es ist dann nicht mehr möglich, in diese Schneidklemmkontaktelemente Kabel einzuführen und zu kontaktieren, so daß die Anschlußmöglichkeiten und Kontaktiervariationen des elektrischen Kabelsteckverbinders durch die Kurzschlußüberbrückung in dieser Form wesentlich verringert werden. Nachteilig ist darüber hinaus, daß das Aufsteckelement kompliziert in der Formgebung ist, schwierig zu positionieren ist und mit angeformten Zinken versehen werden muß, um eine ausreichende Kontaktsicherheit herzustellen. Darüber hinaus behindert das von oben auf die Schneidklemmkontaktelemente aufzusteckende Überbrückungselement das Verschließen des Gehäuses des Steckverbinders durch einen Deckel.Such an electrical cable connector is from DE-OS 38 04 950 known. Electrical contact elements are in a row in one Plastic housing arranged and designed as leaf spring contacts, the corresponding conductor tracks in insulation displacement technology with the respective Contact springs are contacted. Such a connector can, for example to be plugged onto the edge of a printed circuit board in order to make the electrical Connection by means of the conductor tracks to those arranged on the circuit board to be able to manufacture electronic components. But it is also possible that Plug the connector onto a special pin header. In different Use cases, it is desirable with such a connector two or more electrical contact elements with short-circuit bridging to provide. It may be necessary to either immediately adjacent to bridge electrical contact elements, or any electrical Bridge contact elements within the row so that individual electrical Contact elements are skipped. To this end, it is known to be essentially one U-shaped, electrically conductive bridging element to be used, which with his two legs each with these on the electrical Contact elements can be plugged on from above and after plugging in with them electrical contact. Disadvantageously, the legs of the Bridging element in the slots of the detected Insulation displacement contact elements and close them practically in full Scope. It is then no longer possible to insert these insulation displacement contact elements Introduce and contact cables, so that the connection options and Contact variations of the electrical cable connector through the Short-circuit bridging in this form can be significantly reduced. Disadvantageous is also that the push-on element is complicated in shape, is difficult to position and must be provided with molded tines, to establish sufficient contact security. It also hampers that to be plugged onto the insulation displacement contact elements from above Bridging element closing the housing of the connector through a lid.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, unter Meidung der genannten Nachteile eine einfach handhabbare Kurzschlußüberbrückung zu schaffen, mit der die Kontaktiermöglichkeiten des Verbinders nicht eingeschränkt werden.Proceeding from this, the object of the invention is to create a short-circuit bridging that is easy to handle, while avoiding the disadvantages mentioned, with which the contacting possibilities of the connector are not restricted.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß im Verbindungsbereich des Kontaktelementes zwischen den beiden Anschlußabschnitten, insbesondere den Schneidklemmkontakten und dem Federzungenpaar, eine von der Seite zugängliche Aussparung ausgebildet ist, daß die Aussparungen mindestens zwei dieser Kontaktelemente durch Eindrücken eines elektrisch leitenden Brückenelementes in Querrichtung miteinander zur Erstellung der Kurzschlußüberbrückung verbunden sind und daß das Brückenelement mit Preßpassung in den Aussparungen angeordnet ist. Hierdurch wird erreicht, daß aufgrund des seitlich angeordneten Brückenelementes keine Bereiche der Kontaktelemente durch das Brückenelement verschlossen werden, die von Hause aus für die Kabelkontaktierung vorgesehen sind, so daß durch die Lehre der Erfindung eine Beeinträchtigung der Kontaktiermöglichkeiten des Steckverbinders vermieden wird. Die Handhabung des Brückenelementes ist durch das Eindrücken in Querrichtung sehr einfach und durch die Preßpassung absolut kontaktsicher. Form und Herstellung der Kurzschlußüberbrückung lassen sich außerordentlich ökonomisch und technisch effektiv gestalten. Die eingangs genannten Nachteile zum Stand der Technik sind in vollem Umfange behoben.The object is inventively achieved in that is formed in the connecting region of the contact element between the two connection portions, in particular the insulation displacement contacts and the spring tongue pair, is accessible from the side of the recess, that the recesses at least two of these contact elements by pushing an electrically conductive bridge member in transverse direction to each other Creation of the short-circuit bridging are connected and that the bridge element is press-fitted in the recesses. This ensures that due to the laterally arranged bridge element, no areas of the contact elements are closed by the bridge element, which are provided for the cable contact from the start, so that an impairment of the contacting possibilities of the connector is avoided by the teaching of the invention. The handling of the bridge element is very easy by pressing in the transverse direction and absolutely reliable by the press fit. The shape and manufacture of the short-circuit bridging can be designed extremely economically and technically effectively. The disadvantages of the prior art mentioned at the outset have been completely eliminated.

Fig. 1 der Zeichnung zeigt in Explosionsdarstellung sämtliche Teile eines elektrischen Kabelsteckverbinders, nämlich ein leeres Kunststoffgehäuse 1 mit einer Mehrzahl in Reihe angeordneter Kammern 2 für eine entsprechende Anzahl von Kontaktelementen 3 und eine Kurzschlußüberbrückung 4.Fig. 1 of the drawing shows all parts of an exploded view electrical cable connector, namely an empty plastic housing 1 with a plurality of chambers 2 arranged in series for a corresponding number of contact elements 3 and a short-circuit bridging 4.

Fig. 2 der Zeichnung zeigt den Kabelsteckverbinder der Fig. 1 in fertig montiertem Zustand mit geöffnetem Gehäusedeckel. Dabei ist in jede Kammer 2 des Kunststoff-Gehäuses 1 ein Kontaktelement 3 eingesetzt und ist die Kurzschlußüberbrückung 4 durch Ausnehmungen 5 des Kunststoff-Gehäuses 1 in die in der Zeichnung linken beiden Kammern mit den eingesetzten Kontaktelementen derart eingeschoben, daß diese beiden Kontaktelemente elektrisch miteinander verbunden sind, indem die isolierend trennende, dazwischen angeordnete Kammerwand des Kunststoff-Gehäuses überbrückt ist. Nähere Einzelheiten zum Aufbau der Kontaktelemente 3 sowie der Kurzschlußüberbrückung 4 ergeben sich aus der nachfolgenden Beschreibung der Fig. 3 bis 5 der Zeichnung.Fig. 2 of the drawing shows the cable connector of Fig. 1 in fully assembled Condition with opened housing cover. It is in each chamber 2 of Plastic housing 1 is a contact element 3 and is the Short-circuit bridging 4 through recesses 5 of the plastic housing 1 in the two chambers on the left in the drawing with the inserted ones Inserted contact elements such that these two contact elements are electrically interconnected by the isolating, intervening chamber wall of the plastic housing is bridged. More details on the structure of the contact elements 3 and Short-circuit bridging 4 result from the following description of the 3 to 5 of the drawing.

In Fig. 3 der Zeichnung sind zwei Kontaktelemente 3 in einer Anordnung nebeneinander in Reihe perspektivisch dargestellt. Es ist die gleiche Anordnung, in der sie in die zugehörigen Kammern 2 des Kunststoff-Gehäuses 1 eingesetzt werden und dann durch die Kammerwände voneinander isolierend getrennt sind. Jedes Kontaktelement 3 weist - in Längsrichtung L gesehen - auf seiner in der Zeichnung oberen Seite einen ersten Anschlußabschnitt 6, nämlich Schneidklemmkontakte 7 zum abisolierfreien Anschluß eines nicht dargestellten Kabels und an der gegenüberliegenden Seite einen zweiten Anschlußabschnitt 8, nämlich ein Federzungenpaar 9, zum Anschluß eines Steckerkontaktstiftes oder einer Leiterbahn auf. Die beiden Anschlußabschnitte 6 und 8 sind etwa mittig durch einen Verbindungsbereich 10 miteinander verbunden, in welchem eine in Querrichtung sich erstreckende Aussparung 11 etwa rechteckiger Form mittig ausgebildet ist. In die beiden Aussparungen 11 der beiden Kontaktelemente 3 ist ein U-förmiges Brückenelement 12 von der Seite her in Querrichtung Q eindrückbar, welches eine elektrisch leitende Verbindung der beiden Kontaktelemente 3 miteinander herstellt und damit eine Kurzschlußüberbrückung darstellt. Die dabei vorhandene Relation zum Gehäuse 1 ist der Fig. 3 der Zeichnung nicht entnehmbar, ist aber aus Fig. 2 der Zeichnung ersichtlich. Demnach durchgreift das Brückenelement 12 das Kunststoff-Gehäuse 1 von außen durch die beiden seitlichen Ausnehmungen 5 und erstrecken sich die freien Schenkel 13, 14 als Kontaktarme in das Innere der benachbarten Kammern 2 und greifen sodann in die Aussparungen 11 der beiden Kontaktelemente 3 der Fig. 3 zwecks Herstellung einer leitenden Verbindung ein. Das Brückenelement 12 muß in die Aussparungen 11 eingedrückt werden, da durch entsprechende Abmessungen der freien Schenkel 13 und 14 einerseits und der Aussparungen 11 andererseits eine Preßpassung als Zwangspassung vorgesehen ist. In Fig. 3 of the drawing, two contact elements 3 are in an arrangement shown side by side in a row in perspective. It's the same arrangement in which they inserted into the associated chambers 2 of the plastic housing 1 and are then insulated from each other by the chamber walls. Each contact element 3 has - seen in the longitudinal direction L - on its in the Drawing top side a first connection section 6, namely Insulation displacement contacts 7 for stripping-free connection of a not shown Cable and on the opposite side a second connection section 8, namely a pair of spring tongues 9, for connecting a plug contact pin or a conductor track. The two connection sections 6 and 8 are approximately in the middle connected to each other by a connection area 10, in which a in Recess 11 extending approximately rectangular shape in the middle is trained. In the two recesses 11 of the two contact elements 3 is a U-shaped bridge element 12 from the side in the transverse direction Q indentable, which is an electrically conductive connection of the two Manufactures contact elements 3 with each other and thus a short-circuit bridging represents. The existing relation to the housing 1 is the Fig. 3 Drawing not removable, but can be seen from Fig. 2 of the drawing. Accordingly, the bridge element 12 passes through the plastic housing 1 of outside through the two lateral recesses 5 and extend the free Legs 13, 14 as contact arms in the interior of the adjacent chambers 2 and then engage in the recesses 11 of the two contact elements 3 of FIG. 3 to establish a conductive connection. The bridge element 12 must be pressed into the recesses 11, as by appropriate Dimensions of the free legs 13 and 14 on the one hand and the recesses 11 on the other hand, an interference fit is provided as a forced fit.

Fig. 4 der Zeichnung verdeutlicht die Möglichkeiten zur Herstellung der Preßpassung über entsprechend eingestellte Maße A-A der Ausnehmungen und B-B der freien Schenkel 13 bzw. 14 des Brückenelementes oder auch durch entsprechende Einstellung der Maße C-C der Aussparungen 11 und dem Maß D-D des Brückenelementes 12. Auch eine Kombination beider Alternativen ist möglich. Zur Erleichterung des Eindrückens des Brückenelementes 12 in Querrichtung in die Aussparungen 11 sind die freien, in der Eindrückbewegung vorlaufenden Enden des Brückenelementes 12 abgeschrägt ausgebildet. Ferner ist das Maß D-D zusätzlich so ausgelegt, daß eine Kontaktierungs- und Kurzschlußprüfung mittels Prüfstift möglich ist.Fig. 4 of the drawing illustrates the possibilities for producing the Press fit over correspondingly set dimensions A-A of the recesses and B-B of the free legs 13 or 14 of the bridge element or by corresponding setting of the dimensions C-C of the recesses 11 and the dimension D-D of the bridge element 12. There is also a combination of both alternatives possible. To facilitate the indentation of the bridge element 12 in Transverse direction in the recesses 11 are the free, in the indentation movement leading ends of the bridge element 12 beveled. Further the dimension D-D is also designed so that a contact and Short-circuit testing using a test pin is possible.

Fig. 5 der Zeichnung zeigt die montierte Kurzschlußüberbrückung 4 an den beiden Kontaktelementen 3 unter Weglassung des Kunststoff-Gehäuses 1. Fig. 5 of the drawing shows the assembled short-circuit bypass 4 on the two Contact elements 3 omitting the plastic housing 1.
