Description

Die Erfindung betrifft ein in einer Kammer eines Gehäuses anzuordnendes, aus einem ebenen Blechstanzteil gebogenes elektrisches Kontaktelement in Schneidklemmtechnik einer Kabelsteckverbindung mit einem Doppelschneidklemmenpaar, das zwischen seinen elastisch auseinanderbiegbaren Klemmschenkeln einen Einführschlitz für die Schneidklemmkontaktierung eines elektrischen Kabels bildet und mit einem Gabelfederpaar, das zwischen seinen Gabelfederschenkeln einen Einführschlitz für die Kontaktierung mit einem Flachmesser-Stecker bildet.The invention relates to an electrical contact element to be arranged in a chamber of a housing and bent from a flat sheet metal stamping part in insulation displacement technology of a cable plug connection with a pair of double insulation piercing clamps, which forms an insertion slot between its elastically deflectable clamping legs for the insulation displacement contacting of an electrical cable and with a pair of fork springs which are located between its fork spring legs forms an insertion slot for contacting a flat blade connector.

Ein solches elektrisches Kontaktelement ist beispielsweise aus der EP-PS 0 416 306 bekannt. Dieses bekannte elektrische Kontaktelement weist an einem Ende ein Doppelschneidklemmenpaar auf, zwischen dessen elastisch auseinanderbiegbaren Klemmschenkeln ein elektrischer Leiter in Schneidklemmtechnik festgelegt werden kann. Das andere Ende des Kontaktelementes ist als Gabelfederpaar ausgebildet, zwischen das zur elektrischen Kontaktierung beispielsweise der Kontaktstift eines Steckers einer elektrischen Steckverbindung eingeschoben werden kann. Um eine sichere Kontaktierung zwischen den Gabelfederschenkeln und dem eingeschobenen Kontaktstift eines Steckers zu gewährleisten, weisen die Gabelfederschenkel nach innen in den Einführschlitz vorstehende Kontaktzonen auf. Diese als Ausprägungen ausgestalteten Kontaktzonen stellen zwar in der Regel einen guten Kontakt zwischen dem Gabelfederpaar und einem eingeschobenen Kontaktstift eines Steckers her, jedoch kann es insbesondere bei der Verwendung eines Flachmesser-Steckers vorkommen, daß die Kontaktzonen im zusammengesteckten Zustand gerade im Bereich des Rastloches des Flachmesser-Steckers liegen und somit kein ausreichend sicherer elektrischer Kontakt gewährleistet ist.Such an electrical contact element is known for example from EP-PS 0 416 306. This known electrical contact element has at one end a pair of double insulation displacement clamps, between the elastically deflectable clamping legs of which an electrical conductor can be fixed using insulation displacement technology. The other end of the contact element is designed as a pair of fork springs, between which, for example, the contact pin of a plug of an electrical plug connection can be inserted for electrical contacting. In order to ensure reliable contacting between the fork spring legs and the inserted contact pin of a plug, the fork spring legs have contact zones protruding inwards into the insertion slot. These configured as contact areas usually make good contact between the pair of fork springs and an inserted contact pin of a connector, but it can happen, especially when using a flat blade connector, that the contact zones in the mated condition just in the area of the locking hole of the Flat knife plug and therefore no sufficiently safe electrical contact is guaranteed.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein elektrisches Kontaktelement derart weiterzuentwickeln, daß stets eine sichere Kontaktierung zwischen den Gabelfederschenkeln und einem eingeschobenen Kontaktstift eines Steckers gewährleistet ist.Based on this, the object of the invention is to further develop an electrical contact element in such a way that reliable contacting between the fork spring legs and an inserted contact pin of a plug is always guaranteed.

Die technische Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß jeder Gabelfederschenkel aus zwei unabhängig voneinander elastisch auslenkbaren Blattfedern gebildet ist und an jeder Blattfeder mindestens eine nach innen in den Einführschlitz vorstehende Kontaktzone ausgebildet ist, wobei die Kontaktzonen zweier Blattfedern eines Gabelfederschenkels seitlich der Längsmittellinie des elektrischen Kontaktelementes ausgebildet sind.The technical solution to this problem is characterized in that each fork spring leg is formed from two independently elastically deflectable leaf springs and at least one contact zone protruding inwards into the insertion slot is formed on each leaf spring, the contact zones of two leaf springs of a fork spring leg laterally of the longitudinal center line of the electrical contact element are trained.

Durch die Ausbildung der Gabelfederschenkel in zwei getrennt auslenkbare Blattfedern mit exzentrisch versetzt angeordneten Kontaktzonen wird einerseits erreicht, daß die Einsteckkraft eines in den Einführschlitz zwischen den Gabelfederschenkeln einzusteckenden Kontaktstiftes reduziert wird und andererseits bei der Verwendung eines mit einem Rastloch versehenen Flachmesser-Steckers eine Kontaktierung im Bereich des Rastloches vermieden wird, da das Rastloch eines Flachmesser-Steckers mittig in einem Flachmesser-Stecker ausgebildet ist.The design of the fork spring legs in two separately deflectable leaf springs with eccentrically offset contact zones on the one hand ensures that the insertion force of a contact pin to be inserted into the insertion slot between the fork spring legs is reduced and, on the other hand, contact is made in the area when using a flat blade plug provided with a locking hole of the locking hole is avoided since the locking hole of a flat blade connector is formed in the center of a flat blade connector.

Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen elektrischen Kontaktelementes sind die Kontaktzonen zweier Blattfedern eines Gabelfederschenkels in Längsrichtung des Gabelfederschenkels versetzt zueinander angeordnet. Durch diese zusätzliche versetzte Anordnung der Kontaktzonen wird auch bei der Benutzung der unterschiedlichsten Kontaktstifte eine sichere elektrische Kontaktierung zwischen den Gabelfederschenkeln und einem in den Einführschlitz eingeschobenen Kontaktstift gewährleistet.According to an advantageous embodiment of the electrical contact element according to the invention, the contact zones of two leaf springs of a fork spring leg are arranged offset to one another in the longitudinal direction of the fork spring leg. This additional staggered arrangement of the contact zones ensures reliable electrical contact between the fork spring legs and a contact pin inserted into the insertion slot even when using a wide variety of contact pins.

Die Sicherheit, einen ausreichenden elektrischen Kontakt herzustellen und insbesondere auch Kantenkontaktierungen zu vermeiden, kann gemäß einer bevorzugten Ausführungsform der Erfindung dadurch verstärkt werden, daß die Kontaktzonen der einen Blattfeder eine punktförmige Kontaktierfläche und die Kontaktzonen der anderen Blattfeder des selben Gabelfederschenkels eine linienförmige Kontaktierfläche aufweisen.According to a preferred embodiment of the invention, the security of establishing sufficient electrical contact and in particular also avoiding edge contacts can be increased by the fact that the contact zones of the one leaf spring have a punctiform contact surface and the contact zones of the other leaf spring of the same fork spring leg have a linear contact surface.

Zur Erlangung eines gleichmäßigen Anpreßdrucks der einzelnen Blattfedern der Gabelfederschenkel an einen eingeschobenen Kontaktstift weisen die Kontaktzonen zweier sich direkt gegenüberliegender Blattfedern die gleiche Kontaktierflächenform auf.In order to achieve a uniform contact pressure of the individual leaf springs of the fork spring legs against an inserted contact pin, the contact zones of two directly opposite leaf springs have the same contact surface shape.

Weitere Einzelheiten und Vorteile ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnungen, in denen ein Ausführungsbeispiel eines erfindungsgemäßen elektrischen Kontaktelementes schematisch dargestellt ist. In den Zeichnungen zeigen:

Further details and advantages emerge from the following description of the associated drawings, in which an exemplary embodiment of an electrical contact element according to the invention is shown schematically. The drawings show:

a side view of an electrical contact element;
Fig. 2
a plan view of the electrical contact element according to FIG. 1 with a flat blade connector before assembly and
Fig. 3
the same electrical contact element according to FIG. 2 with inserted flat knife plug.

Das in Fig. 1 dargestellte elektrische Kontaktelement 1 besteht aus einem einstückigen Blechstanzteil, aus dem das elektrische Kontaktelement 1 durch aufeinanderfolgende Biegevorgänge gebogen wird. Aus dem ebenen Blechstanzteil erhält man dann ein elektrisches Kontaktelement 1, wie dies in den Abbildungen Fig. 1 bis 3 dargestellt ist.The electrical contact element 1 shown in Fig. 1 consists of a one-piece stamped sheet metal part, from which the electrical contact element 1 is bent by successive bending processes. An electrical contact element 1 is then obtained from the flat sheet metal stamped part, as shown in FIGS. 1 to 3.

Um an dem elektrischen Kontaktelement 1 ein elektrisches Kabel 2 in der sogenannten Schneidklemmtechnik kontaktieren zu können, weist das elektrische Kontaktelement 1 zwei parallel zueinander angeordnete Doppelschneidklemmenpaare 3 auf. Jedes dieser Doppelschneidklemmenpaare 3 besteht aus zwei Klemmschenkeln 3a, die zwischen sich einen Einführschlitz 3b für das elektrische Kabel 2 bilden.In order to be able to contact an electrical cable 2 in so-called insulation displacement technology on the electrical contact element 1, the electrical contact element 1 has two pairs of double insulation displacement clamps 3 arranged parallel to one another. Each of these double insulation displacement pairs 3 consists of two clamping legs 3a, which form an insertion slot 3b between them for the electrical cable 2.

Zum Kontaktieren des elektrischen Kontaktelementes 1 mit dem Kontaktstift eines Steckers einer elektrischen Steckverbindung, beispielsweise einem Flachmesser-Stecker 4, weist das elektrische Kontaktelement 1 an dem dem Doppelschneidklemmenpaar 3 gegenüberliegenden freien Ende ein Gabelfederpaar 5 auf. Das Gabelfederpaar 5 besteht aus zwei Gabelfederschenkeln 5a, die zwischen sich einen Einführschlitz 5b für einen Kontaktstift eines Steckers bilden. Wie aus Fig. 2 und 3 ersichtlich, besteht jeder Gabelfederschenkel 5a aus zwei getrennten Blattfedern 5c.In order to contact the electrical contact element 1 with the contact pin of a plug of an electrical plug connection, for example a flat blade plug 4, the electrical contact element 1 has a fork spring pair 5 at the free end opposite the pair of double insulation displacement clamps 3. The pair of fork springs 5 consists of two fork spring legs 5a, which form an insertion slot 5b between them for a contact pin of a plug. As can be seen from FIGS. 2 and 3, each fork spring leg 5a consists of two separate leaf springs 5c.

Um einen sicheren elektrischen Kontakt zwischen den Gabelfederschenkeln 5a und einem in den Einführschlitz 5b eingeschobenen Kontaktstift eines Steckers zu gewährleisten, sind an jeder Blattfeder 5c nach innen in den Einführschlitz 5b vorstehende Kontaktzonen 6 ausgebildet, wie dies aus Fig. 1 ersichtlich ist.In order to ensure reliable electrical contact between the fork spring legs 5a and a contact pin of a plug inserted into the insertion slot 5b, contact zones 6 protruding inwards into the insertion slot 5b are formed on each leaf spring 5c, as can be seen from FIG. 1.

In den Abbildungen Fig. 2 und 3 ist die Kontaktierung eines elektrischen Kontaktelementes 1 mit einem Flachmesser-Stecker 4 dargestellt. Zum Kontaktieren wird der Flachmesser-Stecker 4 in den Einführschlitz 5b des Gabelfederpaares 5 eingeschoben, wodurch die Gabelfederschenkel 5a auseinandergebogen werden. Aufgrund der geteilten Ausbildung der Gabelfederschenkel 5a als einzelne Blattfedern 5c wird die Einsteckkraft reduziert, da die einzelnen Blattfedern 5c aufgrund ihrer geringeren Breite elastischer sind als ein einzelner Gabelfederschenkel 5a. Die an den Blattfedern 5c vorzugsweise durch Eindrücken ausgebildeten Kontaktzonen 6 sind in Längsrichtung des Gabelfederschenkels 5a versetzt zueinander und exzentrisch zur Längsmittellinie des Kontaktelementes 1 ausgebildet, wobei die Kontaktzonen 6 der Blattfedern 5c eines Gabelfederschenkels 5a unterschiedlich ausgestaltete Kontaktierflächen 6a aufweisen.2 and 3, the contacting of an electrical contact element 1 with a flat blade connector 4 is shown. To make contact, the flat blade plug 4 is inserted into the insertion slot 5b of the pair of fork springs 5, as a result of which the fork spring legs 5a are bent apart. Due to the split design of the fork spring legs 5a as individual leaf springs 5c, the insertion force is reduced, since the individual leaf springs 5c are more elastic than a single fork spring leg 5a due to their smaller width. The contact zones 6, which are formed on the leaf springs 5c, preferably by being pressed in, are offset in the longitudinal direction of the fork spring leg 5a relative to one another and eccentrically to the longitudinal center line of the contact element 1, the contact zones 6 of the leaf springs 5c of a fork spring leg 5a having differently configured contact surfaces 6a.

Die versetzte Anordnung der Kontaktzonen 6 bewirkt, daß bei vollständig in den Einführschlitz 5b eingeschobenem Flachmesser-Stecker 4, wie dies in Fig. 3 dargestellt ist, die Kontaktzonen 6 der Gabelfederschenkel 5a nicht im Bereich eines Rastloches 4a des Flachmesser-Steckers 4 zur Anlage an dem Flachmesser-Stecker 4 kommen, wodurch sich ein unzureichender elektrischer Kontakt ergeben könnte. Bei dieser in Fig. 3 dargestellten Ausführungsform ist gut zu erkennen, daß die Kontaktzonen 6 mit ihren Kontaktierflächen 6a in einigem Abstand zu dem Rastloch 4a des Flachmesser-Steckers 4 an dem Flachmesser-Stecker 4 anliegen.The staggered arrangement of the contact zones 6 has the effect that when the flat-blade connector 4 is fully inserted into the insertion slot 5b, as shown in FIG. 3, the contact zones 6 of the fork spring legs 5a do not abut in the area of a locking hole 4a of the flat-blade connector 4 the flat blade connector 4 come, which could result in insufficient electrical contact. In this embodiment shown in Fig. 3 it can be clearly seen that the contact zones 6 with their contact surfaces 6a in some distance from the locking hole 4a of the flat blade connector 4 on the flat blade connector 4.

Mit einem solchermaßen ausgestalteten elektrischen Kontaktelement 1 ist es somit einerseits möglich, die Einsteckkraft zur Kontaktierung mit dem Kontaktstift eines Steckers zu reduzieren und andererseits einen jederzeit ausreichenden Kontakt zwischen den Kontaktzonen 6 der Gabelfederschenkel 5a und dem eingesteckten Kontaktstift eines Steckers zu gewährleisten.With an electrical contact element 1 designed in this way, it is thus possible, on the one hand, to reduce the insertion force for contacting the contact pin of a plug and, on the other hand, to ensure sufficient contact between the contact zones 6 of the fork spring legs 5a and the inserted contact pin of a plug at all times.
