The contact has at least two limbs, at least one web region (20) between the limbs, an electrically conductive jacket (18) that is in contact with the web region, and a jacketed region where the jacket partially surrounds the two limbs. The limbs provide contact positions for contacting the mating contact within the jacketed region.

Description

Die Erfindung betrifft eine elektrische Verbindungseinrichtung mit einem Gabelkontakt zur Herstellung einer elektrischen Verbindung mit einem Gegenkontakt.The invention relates to an electrical connection device with a fork contact for producing an electrical connection with a mating contact.

Gabelkontakte, das heißt Kontakte mit zwei Kontaktschenkeln oder -abschnitten, die beispielsweise aufrecht oder waagerecht angeordnet sein können, dienen häufig der Herstellung einer elektrischen sowie einer mechanischen Verbindung mit einem zungenartigen Gegenkontakt. Dabei kann dieser Gegenkontakt beispielsweise einem Relais, einer Sicherung und/ oder dergleichen zugeordnet sein. Von Nachteil bei einer solchen Verbindung ist die begrenzte Stromtragfähigkeit aufgrund der erhöhten Wärmeentwicklung im Gabelkontakt. Herkömmliche Lösungen, die diesen Nachteil zum Teil wettmachen, führen zu einer größeren Bauhöhe.Fork contacts, that is contacts with two contact legs or sections, which may be arranged, for example, upright or horizontal, often serve to produce an electrical and a mechanical connection with a tongue-like mating contact. In this case, this counter contact can be associated, for example, a relay, a fuse and / or the like. The disadvantage of such a connection is the limited current carrying capacity due to the increased heat development in the fork contact. Conventional solutions that compensate for this disadvantage in part, lead to a greater height.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte elektrische Verbindungseinrichtung der eingangs genannten Art zu schaffen, bei der die zuvor genannten Nachteile beseitigt sind.The invention has for its object to provide an improved electrical connection device of the type mentioned, in which the aforementioned disadvantages are eliminated.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Gabelkontakt mit einer elektrisch leitenden Umhüllung versehen ist, die einerseits insbesondere mit dem Stegbereich des Gabelkontaktes in Kontakt steht und andererseits in den Bereichen, in denen sie die beiden Schenkel des Gabelkontaktes umgibt, Kontaktstellen mit dem Gegenkontakt besitzt.This object is achieved according to the invention in that the fork contact is provided with an electrically conductive sheath which is on the one hand in particular with the web portion of the fork contact in contact and on the other hand, in the areas in which it surrounds the two legs of the fork contact points of contact Owns mating contact.

Aufgrund dieser Ausbildung besteht nunmehr die Möglichkeit, den Gabelkontakt mit einer elektrisch leitenden Umhüllung zu versehen, die ohne Vergrößerung der Bauhöhe einen zusätzlichen Strompfad schafft und damit die Hitzeerzeugung reduziert. Auch diese elektrisch leitende Umhüllung kann ebenso wie der Gabelkontakt beispielsweise zwei schenkelartige Abschnitte umfassen. Mit der elektrisch leitenden Umhüllung kann also beispielsweise ein weiterer Strompfad zwischen beispielsweise einem Relaiskontakt und einer Zentralelektrik-Schnittstelle geschaffen werden, was mit der bisher üblichen zusätzlichen Hülse aus rostfreiem Stahl zur Erhöhung der normalen Kontaktkraft nicht möglich war (siehe beispielsweise WO 03/028158 A , das alle Merkmale des Oberbegriffs von Anspruch 1 zeigt). Damit kann also insbesondere auch dem Umstand Rechnung getragen werden, dass in der Zentralelektrik unterschiedliche Belastungsströme auftreten können. Nachdem mit der elektrisch leitenden Umhüllung die Bauhöhe nicht vergrößert wird, werden Mehrkosten eingespart. Mit der klein gehaltenen Bauhöhe ergeben sich auch Vorteile hinsichtlich der jeweiligen Einbausituation.Due to this design, it is now possible to provide the fork contact with an electrically conductive sheath, which creates an additional current path without increasing the height and thus reduces heat generation. Also, this electrically conductive sheath may include as well as the fork contact, for example, two leg-like portions. Thus, for example, a further current path between, for example, a relay contact and a central electrical interface can be created with the electrically conductive enclosure, which was not possible with the hitherto customary additional sleeve made of stainless steel for increasing the normal contact force (see, for example WO 03/028158 A showing all the features of the preamble of claim 1). Thus, in particular, the circumstance can be taken into account that different load currents can occur in the central electrics. After the height is not increased with the electrically conductive sheath, additional costs are saved. With the small height, there are also advantages in terms of the respective installation situation.

Mit der elektrisch leitenden Umhüllung werden also ohne Vergrößerung der Bauhöhe zusätzliche Kontaktpunkte zum Gegenstecker beispielsweise eines Relais oder einer Sicherung erzeugt, und zwar mit dem positiven Effekt einer Reduzierung der Wärmeentwicklung in der Zentralelektrik und einer verbesserten Stromtragfähigkeit. Die elektrisch leitende Umhüllung bildet eine zusätzliche Brücke zwischen dem Gegenstück wie beispielsweise einem Relais oder einer Sicherung und beispielsweise einer Stromschiene, mit der der Gabelkontakt verbunden sein kann.With the electrically conductive sheath, additional contact points to the mating connector, for example, of a relay or a fuse are thus produced without increasing the height, with the positive effect of reducing the heat development in the central electrical system and improved current carrying capacity. The electrically conductive sheath forms an additional bridge between the counterpart such as a relay or a fuse and, for example, a bus bar, with which the fork contact can be connected.

Gemäß einer bevorzugten praktischen Ausführungsform der elektrischen Verbindungseinrichtung ist die Umhüllung zur Bildung der Kontaktstellen mit dem Gegenkontakt mit Ansätzen versehen, die von den die beiden Schenkel des Gabelkontaktes umgebenden Bereichen der Umhüllung in einen dazwischenliegenden, den Gegenkontakt aufnehmenden Spalt vorspringen.According to a preferred practical embodiment of the electrical connection means, the envelope is provided with projections for forming the contact points with the mating contact, which extends from the areas of the envelope surrounding the two legs of the fork contact to project an intermediate gap receiving the mating contact.

Zweckmäßigerweise ist der Spalt der Umhüllung mit dem Spalt des Gabelkontaktes ausgerichtet.Conveniently, the gap of the enclosure is aligned with the gap of the fork contact.

Bevorzugt weist die Umhüllung auf jeder Seite ihres Spaltes jeweils wenigstens zwei mit dem Gegenkontakt in Kontakt tretende Ansätze auf. Dabei liegen vorteilhafterweise jeweils zwei der mit dem Gegenkontakt in Kontakt tretenden Ansätze der Umhüllung einander gegenüber.The sheath preferably has on each side of its gap at least two lugs which come into contact with the mating contact. In each case, two of the approaches of the enclosure that come into contact with the mating contact are advantageously opposite each other.

Bei einer bevorzugten praktischen Ausführungsform der elektrischen Verbindungseinrichtung ist die Umhüllung zur Bildung der Kontaktstellen mit dem Gegenkontakt mit vier Ansätzen versehen, von denen jeweils zwei einander gegenüberliegen.In a preferred practical embodiment of the electrical connection device, the envelope is provided with four projections for forming the contact points with the mating contact, two of which are opposite each other.

Bevorzugt ist die Umhüllung im Bereich der freien Enden der beiden Schenkel des Gabelkontaktes mit entsprechenden Ansätzen versehen.Preferably, the envelope is provided in the region of the free ends of the two legs of the fork contact with corresponding lugs.

Zweckmäßigerweise ist die Umhüllung ausgehend von einem geschlitzten Flachteil mit einem Basisabschnitt und einem sich von diesem weg erstreckenden länglichen Abschnitt gebildet, wobei der längliche Abschnitt um die freien Schenkelenden des Gabelkontaktes und der Basisabschnitt seitlich um den Stegbereich des Gabelkontaktes gebogen ist.Conveniently, the wrapper is formed from a slotted flat portion having a base portion and an elongated portion extending therefrom, the elongate portion being bent about the free leg ends of the fork contact and the base portion laterally about the land portion of the fork contact.

Bevorzugt ist die Umhüllung durch ein Stanzteil gebildet.Preferably, the envelope is formed by a stamped part.

Von Vorteil ist insbesondere auch, wenn sich der um die freien Schenkelenden des Gabelkontaktes gebogene längliche Abschnitt der Umhüllung mit seinem freien Ende bis in den Stegbereich des Gabelkontaktes erstreckt. Von Vorteil ist hierbei, wenn der seitlich um den Stegbereich des Gabelkontaktes gebogene Basisabschnitt der Umhüllung zumindest teilweise den Bereich des freien Endes seines um die freien Schenkelenden des Gabelkontaktes gebogenen länglichen Abschnitts überdeckt.It is also particularly advantageous if the elongated section of the envelope bent around the free leg ends of the fork contact has its free end extending into the web region of the fork contact extends. It is advantageous in this case if the base section of the enclosure bent laterally around the web region of the fork contact at least partially covers the region of the free end of its elongated section bent around the free leg ends of the fork contact.

Zweckmäßigerweise erstreckt sich der Basisabschnitt der Umhüllung über die Höhe des Steckbereichs des Kabelkontaktes hinaus über einen bestimmten Bereich der beiden Schenkel des Gabelkontaktes. Dabei ist es von Vorteil, wenn der seitlich um den Stegbereich des Gabelkontaktes und bereichsweise über dessen beide Schenkel gebogene Basisabschnitt der Umhüllung den um die freien Schenkelenden des Gabelkontaktes gebogenen länglichen Abschnitt überdeckt.Appropriately, the base portion of the enclosure extends beyond the height of the mating portion of the cable contact beyond a certain range of the two legs of the fork contact. It is advantageous if the laterally around the web portion of the fork contact and partially over the two legs bent base portion of the envelope covers the bent around the free leg ends of the fork contact elongated portion.

Bei einer bevorzugten praktischen Ausführungsform besteht die Umhüllung aus einer Kupferknetlegierung. Dabei soll die Umhüllung bevorzugt eine gute elektrische Leitfähigkeit sowie eine gute thermische Relaxationsbeständigkeit besitzen.In a preferred practical embodiment, the enclosure consists of a copper wrought alloy. The sheath should preferably have a good electrical conductivity and a good thermal relaxation resistance.

Gemäß einer bevorzugten praktischen Ausführungsform besitzt die vorzugsweise ausgehend von einem Flach- oder Stanzteil gebildete Umhüllung eine Materialdicke in einem Bereich von etwa 0,4 mm.According to a preferred practical embodiment, the envelope preferably formed from a flat or stamped part has a material thickness in a range of about 0.4 mm.

Auch der Gabelkontakt kann zweckmäßigerweise eine Materialdicke in einem Bereich von etwa 0,8 mm besitzen.Also, the fork contact may suitably have a material thickness in a range of about 0.8 mm.

Wie bereits erwähnt, ist der Gabelkontakt zweckmäßigerweise mit einer Stromschiene verbunden.As already mentioned, the fork contact is expediently connected to a busbar.

Figur 1 zeigt in schematischer perspektivischer Darstellung eine elektrische Verbindungseinrichtung 10 mit einem Gabelkontakt 12 zur Herstellung einer elektrischen Verbindung mit einem Gegenkontakt 14. FIG. 1 shows a schematic perspective view of an electrical connection device 10 with a fork contact 12 for establishing an electrical connection with a mating contact 14th

Der Kabelkontakt 12 kann mit einer Stromschiene 16 verbunden sein. Der im vorliegenden Fall beispielsweise zungenartige Gegenkontakt 14 kann beispielsweise einem Relais, einer Sicherung oder dergleichen zugeordnet sein.The cable contact 12 may be connected to a bus bar 16. The example in the present case tongue-like mating contact 14 may for example be associated with a relay, a fuse or the like.

Der Gabelkontakt 12 ist mit einer elektrisch leitenden Umhüllung 18 versehen. Diese Umhüllung 18 kann einerseits insbesondere mit dem Stegbereich 20 des Gabelkontaktes 12 in Kontakt stehen (vgl. z.B. die Kontaktbereiche 38 in Figur 3), während sie andererseits in den Bereichen, in denen sie die beiden Schenkel 22 (vgl. insbesondere Figur 2) des Gabelkontaktes 12 umgibt, Kontaktstellen mit dem Gegenkontakt 14 besitzt, die im vorliegenden Fall durch Ansätze 24 (vgl. insbesondere wieder Figur 2) gebildet sind.The fork contact 12 is provided with an electrically conductive sheath 18. On the one hand, this sheath 18 may be in contact in particular with the web region 20 of the fork contact 12 (cf., for example, the contact regions 38 in FIG FIG. 3 On the other hand, in the areas in which they the two legs 22 (see, in particular FIG. 2 ) of the fork contact 12 surrounds, contact points with the mating contact 14 has, which in the present case by lugs 24 (see FIG. 2 ) are formed.

In der Figur 2 ist der in Figur 1 erkennbare Gabelkontakt 12 mit zugeordneter elektrisch leitender Umhüllung 18 nochmals in schematischer perspektivischer Darstellung wiedergegeben. Im vorliegenden Fall ist der Gegenkontakt der Übersichtlichkeit halber weggelassen.In the FIG. 2 is the in FIG. 1 recognizable fork contact 12 with associated electrically conductive sheath 18 again shown in a schematic perspective view. In the present case, the mating contact is omitted for clarity.

Die elektrisch leitende Umhüllung 18 ist zur Bildung der Kontaktstellen mit dem Gegenkontakt 14 (vgl. Figur 1) also mit Ansätzen 24 versehen. Wie insbesondere anhand der Figur 2 zu erkennen ist, sind diese Ansätze 24 ausgehend von dem die beiden Schenkel 22 des Gabelkontaktes 12 umgebenden Bereichen der Umhüllung 18 in den dazwischenliegenden, den Gegenkontakt 14 (vgl. Figur 1) aufnehmenden Spalt 26 gerichtet.The electrically conductive sheath 18 is to form the contact points with the mating contact 14 (see. FIG. 1 ) so provided with lugs 24. As in particular on the basis of FIG. 2 can be seen, these approaches are 24 starting from the two legs 22 of the fork contact 12 surrounding areas of the enclosure 18 in the intermediate, the mating contact 14 (see. FIG. 1 ) receiving gap 26 directed.

Dabei ist dieser Spalt 26 der Umhüllung 18 mit dem Spalt 28 des Gabelkontaktes 12 ausgerichtet.In this case, this gap 26 of the casing 18 is aligned with the gap 28 of the fork contact 12.

Wie insbesondere wieder anhand der Figur 2 zu erkennen ist, weist die Umhüllung 18 im vorliegenden Fall auf jeder Seite ihres Spaltes 26 jeweils wenigstens zwei mit dem Gegenkontakt 14 (vgl. Figur 1) in Kontakt tretende Ansätze 24 auf. Dabei liegen jeweils zwei der mit dem Gegenkontakt 14 in Kontakt tretenden Ansätze 24 der Umhüllung 18 einander gegenüber.How in particular on the basis of the FIG. 2 can be seen, the sheath 18 in the present case on each side of its gap 26 each have at least two with the mating contact 14 (see. FIG. 1 ) contacting lugs 24. There are two each with the mating contact 14 contacting lugs 24 of the enclosure 18 to each other.

Beim vorliegenden Ausführungsbeispiel ist die Umhüllung 18 zur Bildung der Kontaktstellen mit dem Gegenkontakt 14 mit genau vier Ansätzen 24 versehen, von denen, wie bereits erwähnt, jeweils zwei einander gegenüberliegen. Dabei ist die Umhüllung 18 im Bereich der freien Enden der beiden Schenkel 22 des Gabelkontaktes 12 mit den betreffenden Ansätzen 24 versehen.In the present embodiment, the sheath 18 is provided to form the contact points with the mating contact 14 with exactly four lugs 24, of which, as already mentioned, in each case two opposite each other. In this case, the envelope 18 is provided in the region of the free ends of the two legs 22 of the fork contact 12 with the respective lugs 24.

Figur 3 zeigt eine Abwicklung der ausgehend von einem Flach- oder Stanzteil gebildeten Umhüllung 18. In der Figur 4 ist die in ihre endgültige Form gebogene Umhüllung 18 in schematischer Vorderansicht wiedergegeben. Figur 5 zeigt die in ihre endgültige Form gebogene Umhüllung 18 in einer schematischen Seitenansicht. Die Figur 6 zeigt die in ihre endgültige Form gebogene Umhüllung 18 nochmals in einer schematischen perspektivischen Ansicht. FIG. 3 shows a settlement of the formed from a flat or stamped part enclosure 18. In the FIG. 4 the envelope 18 bent into its final shape is shown in a schematic front view. FIG. 5 shows the bent into its final shape envelope 18 in a schematic side view. The FIG. 6 shows the bent into its final shape envelope 18 again in a schematic perspective view.

Wie den Figuren 3 bis 6 entnommen werden kann, kann die Umhüllung 18 insbesondere ausgehend von einem geschlitzten Flachteil mit einem Basisteil 30 und einem sich von diesem weg erstreckenden länglichen Abschnitt 32 gebildet sein. Dabei wird der längliche Abschnitt 32 um die freien Schenkelenden 34 des Gabelkontaktes 12 (vgl. auch Figur 2) und der Basisabschnitt 30 seitlich um den Stegbereich 20 des Gabelkontaktes 12 gebogen.Like that FIGS. 3 to 6 can be removed, the sheath 18 may be formed in particular starting from a slotted flat part with a base portion 30 and an extending therefrom elongated portion 32. In this case, the elongated portion 32 about the free leg ends 34 of the fork contact 12 (see also FIG. 2 ) and the base portion 30 laterally bent around the web portion 20 of the fork contact 12.

Der um die freien Schenkelenden 34 des Gabelkontaktes 12 gebogene längliche Abschnitt 32 der Umhüllung 18 erstreckt sich mit seinem freien Ende 36 bis in den Bereich des Steges 20 des Gabelkontaktes 12 (vgl. auch nochmals die Figuren 1 und 2). Dabei schließt im vorliegenden Fall dieses freie Ende 36 des umgebogenen länglichen Abschnitts 32 der Umhüllung 18 bündig mit der Unterkante des Basisabschnitts 30 ab (vgl. insbesondere die Figuren 4 und 6).The bent around the free leg ends 34 of the fork contact 12 elongated portion 32 of the enclosure 18 extends with its free end 36 into the region of the web 20 of the fork contact 12 (see also again the FIGS. 1 and 2 ). This concludes in the present case this free end 36 of the bent elongated portion 32 of the enclosure 18 flush with the lower edge of the base portion 30 from (see in particular the FIGS. 4 and 6 ).

Wie insbesondere wieder anhand der Figuren 4 und 6 zu erkennen ist, überdeckt der seitlich um den Stegbereich des Gabelkontaktes 12 gebogene Basisabschnitt 30 der Umhüllung 18 zumindest teilweise den Bereich des freien Endes 36 seines um die freien Schenkelenden 34 des Gabelkontaktes 12 nach unten gebogenen länglichen Abschnitts 32.How in particular on the basis of the FIGS. 4 and 6 it can be seen, the base portion 30 of the sheath 18 bent laterally around the web area of the fork contact 12 at least partially covers the area of the free end 36 of its oblong portion 32 bent downwards around the free leg ends 34 of the fork contact 12.

Im vorliegenden Fall erstreckt sich der Basisabschnitt 30 der Umhüllung 18 über die Höhe des Stegbereichs des Gabelkontaktes 12 hinaus über einen bestimmten Bereich der beiden Schenkel 22 des Gabelkontaktes 12.In the present case, the base portion 30 of the sheath 18 extends beyond the height of the land area of the fork contact 12 beyond a certain area of the two legs 22 of the fork contact 12.

Dabei überdeckt der seitlich um den Stegbereich des Gabelkontaktes 12 und bereichsweise über dessen beide Schenkel 22 gebogene Basisabschnitt 30 der Umhüllung 18 über eine entsprechende Länge auch den die um die freien Schenkelenden 34 des Gabelkontaktes 12 (vgl. auch nochmals Figur 2) gebogenen länglichen Abschnitt 30.In this case, the laterally around the web portion of the fork contact 12 and partially over the two legs 22 curved base portion 30 of the sheath 18 over a corresponding length also covers the to the free leg ends 34 of the fork contact 12 (see also again FIG. 2 ) bent elongate section 30.

Die Umhüllung 18 kann vorteilhafterweise aus einer Kupferknetlegierung mit einer guten elektrischen Leitfähigkeit und einer guten thermischen Relaxationsbeständigkeit bestehen.The sheath 18 may advantageously consist of a copper wrought alloy with a good electrical conductivity and a good thermal relaxation resistance.

Die im vorliegenden Fall ausgehend von einem Flach- oder Stanzteil gebildete Umhüllung 18 besitzt vorzugsweise eine Materialdicke in einem Bereich von etwa 0,4 mm.The envelope 18 formed in the present case starting from a flat or stamped part preferably has a material thickness in a range of about 0.4 mm.

Auch der Gabelkontakt 12 kann beispielsweise eine Materialdicke in einem Bereich von etwa 0,8 mm besitzen.Also, the fork contact 12 may, for example, have a material thickness in a range of about 0.8 mm.

Die elektrisch leitende Umhüllung 18 erzeugt also zusätzliche Kontaktpunkte zu dem beispielsweise einem Relais, einer Sicherung oder dergleichen zugeordneten Gegenkontakt 14, ohne dass dabei die Bauhöhe vergrößert wird. Entsprechend werden Mehrkosten eingespart und die Einbausituation verbessert. Mit den zusätzlichen Kontaktpunkten zum Gegenkontakt oder Gegenstecker wird die Wärmeentwicklung in der Zentralelektrik auf ein Minimum reduziert und die Stromtragfähigkeit verbessert. Die elektrisch leitende Umhüllung 18 stellt also eine zusätzliche Brücke zwischen dem beispielsweise einem Relais oder einer Sicherung zugeordneten Gegenkontakt 14 und der Stromschiene 16 dar.The electrically conductive sheath 18 thus generates additional contact points to the example, a relay, a fuse or the like associated counter contact 14, without causing the height is increased. Accordingly, additional costs are saved and the installation situation improved. With the additional contact points to the mating contact or mating connector, the heat development in the central electrical system is reduced to a minimum and the current carrying capacity is improved. The electrically conductive sheath 18 thus represents an additional bridge between the example, a relay or a fuse associated mating contact 14 and the busbar 16.
