Abstract

The contact socket is used for the connection of mating contacts, especially in the form of flat contact tongues. It comprises a contact spring support (1), which comprises at least one supporting wall (2' or 3') on whose inside a row of domed contact springs (4') is arranged. In this case, at least one end (6') of each contact spring (4) is bent round on the outside of the supporting wall (2', 3'). These contact springs expand elastically, to make contact, when a mating contact is inserted. Particularly economical manufacture is provided in that the contact springs (43') are designed integrally with the supporting wall (2', 3'), in each case being bent back onto it, adjacent to it, and the respective free end (8') of the contact springs (4') being bent back around the corresponding supporting wall edge (10'). Each supporting wall (2', 3') is stamped from a metal sheet (33), together with the associated contact springs (4'). The thickness of the metal sheet (33) can in this case be stepped. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Kontaktbuchse für den Anschluß von Gegenkontakten, insbesondere in Form von Flachkontaktzungen, mit einem Kontaktfederträger, der mindestens eine Tragwand umfaßt, an deren Innenseite eine Reihe von gewölbten Kontaktfedern angeordnet ist, die sich bei Einführung eines Gegenkontaktes unter Kontaktgabe elastisch aufweiten, wobei zumindest ein Ende jeder Kontaktfeder an der Außenseite der Tragwand umgebogen ist.The invention relates to a contact socket for the connection of mating contacts, in particular in the form of flat contact tongues, with a contact spring support which comprises at least one supporting wall, on the inside of which a series of curved contact springs is arranged, which expand elastically when a mating contact is introduced while making contact , wherein at least one end of each contact spring on the outside of the support wall is bent.

Bei einer bekannten Kontaktbuchse dieser Art (DE-B-1 0 33 751 sind die Tragwände mit stirnseitigen Vorsprüngen versehen, die ihrer Aufnahme dienende schlitzartige Ausnehmungen in Abschlußplatten durchsetzen, mit denen sie verbunden sind. Der gegenseitige Abstand dieser Abschlußplatten, der der Länge der Tragwände entspricht, bestimmt die Zahl der nebeneinander aufgereihten, durch Kontaktfederdrahtabschnitte gebildeten, gewölbten Kontaktfedern. Die Herstellung, Vorformung und Einder Tragwände entspricht, bestimmt die Zahl der nebeneinander aufgereihten, durch Kontaktfederdrahtabschnitte gebildeten, gewölbten Kontaktfedern. Die Herstellung, Vorformung und Einbringung der Kontaktfedern hat sich als sehr arbeits- und zeitaufwendig und entsprechend kostspielig erwiesen.In a known contact socket of this type (DE-B-1 0 33 751), the supporting walls are provided with frontal projections which penetrate slot-like recesses in their end plates, with which they are connected corresponds to the number of side-by-side, curved contact springs formed by contact spring wire sections determines the manufacture, preforming and Einder Walls correspond to, determines the number of side-by-side, arched contact springs formed by contact spring wire sections. The production, preforming and introduction of the contact springs has proven to be very laborious and time-consuming and accordingly expensive.

Es hat sich nun gezeigt, daß eine einfachere und damit kostengünstigere Herstellung möglich ist, wenn die Kontaktfedern einstückig mit der Tragwand, sich an diese zurückgebogen anschließend ausgeführt sind und das jeweilige freie Ende der Kontaktfedern um die entsprechende Tragwandkante zurückgebogen ist. In diesem Fall müssen die Kontaktfedern nur an einem Ende zurückgebogen werden. Die Montage ist dadurch denkbar einfach.It has now been shown that a simpler and therefore more cost-effective production is possible if the contact springs are made in one piece with the supporting wall, are then bent back to this and the respective free end of the contact springs is bent back around the corresponding supporting wall edge. In this case, the contact springs only have to be bent back at one end. This makes installation very easy.

Zur weiteren Vereinfachung kann dabei jede Tragwand zusammen mit den zugehörigen Kontaktfedern aus einem Blech gestanzt sein bzw. werden.For further simplification, each support wall can be stamped out of a sheet metal together with the associated contact springs.

Selbstverständlich können Tragwände und Kontaktfedern aus einem Blech mit konstanter Dicke bzw. Stärke ausgestanzt sein. An die Tragwände als tragende bzw. haltende Elemente werden jedoch im Hinblick auf beispielsweise ihre Biegesteifigkeit ganz andere Anforderungen gestellt als an die Kontaktfedern. Es ist daher erfindungsgemäß bevorzugt, daß das Blech, aus dem die Tragwand und die zugehörigen Kontaktfedern gestanzt werden, in seiner Stärke gestuft ist. Beispielsweise kann dabei derjenige Teil des Bleches, der die spätere Tragwand bildet, stärker ausgeführt sein, als der später die Kontaktfedern bildende Teil.Of course, supporting walls and contact springs can be punched out of sheet metal with a constant thickness or thickness. However, with regard to, for example, their bending rigidity, very different requirements are placed on the supporting walls as load-bearing or holding elements than on the contact springs. It is therefore preferred according to the invention that the thickness of the sheet metal from which the supporting wall and the associated contact springs are punched is graded. For example, the part of the sheet which forms the later supporting wall can be made stronger than the part which later forms the contact springs.

Die in der Zeichnung ersichtliche Kontaktbuchse dient dem Anschluß nicht dargestellter Flachkontaktzungen, insbesondere von Flachkontaktzungen mit den im Automobilbau üblichen Abmessungen 5,7 x 0,7 x 7,5 mm bzw. 2,8 x 0,7 x 7,5 mm. Sie umfaßt einen Kontaktfederträger 1 mit zwei zueinander parallelen Tragwänden 2,3, auf deren mindestens einer, vorzugsweise beiden Innenseite(n) jeweils eine Reihe von derart gewölbten Kontaktfedern 4 angeordnet ist/sind, daß von den aufeinanderzu gerichteten Wölbungen ein sich bei Einführung einer Flachkontaktzunge unter Kontaktgabe elastisch aufweitender Spalt 5 gebildet ist. Die beiden Enden 6,7 jeder Kontaktfeder 4 sind an der Außenseite der zugehörigen Tragwand 2,3 aufeinanderzu umgebogen. Der Abstand der beiden Umbiegestellen 8,9 jeder Kontaktfeder 4 voneinander ist in gestrecktem Zustand um ein die Größe der Kontaktfederwölbung bestimmendes Maß größer gewählt als der Abstand der Tragwandkanten 10,11, auf denen die aufeinanderzu umgebogenen Enden 6,7 der Kontaktfedern aufliegen.The contact socket shown in the drawing is used to connect flat contact tongues, not shown, in particular flat contact tongues with the dimensions of 5.7 x 0.7 x 7.5 mm or 2.8 x 0.7 x 7.5 mm which are common in automobile construction. It comprises a contact spring support 1 with two mutually parallel supporting walls 2, 3, on the at least one, preferably both inside (s) of which a number of contact springs 4 curved in such a way is / are arranged that one of the bulges facing one another is introduced when a flat contact tongue is introduced is formed with contact elastically widening gap 5. The two ends 6, 7 of each contact spring 4 are bent towards one another on the outside of the associated support wall 2, 3. The distance of the two bending points 8, 9 of each contact spring 4 from one another is chosen to be larger by a dimension determining the size of the contact spring curvature than the distance of the supporting wall edges 10, 11, on which the bent ends 6.7 of the contact springs lie.

Die beiden Tragwände 2,3 sind über eine den Abstand der Tragwände voneinander bestimmende Querwand 12 miteinander verbunden. An den der Querwand 12 abgelegenen Kanten 10,11 der Tragwände 2,3 ist eine den Einführungsspalt 5 für die Flachkontaktzunge begrenzende Stützwand 14 vorgesehen. Die Stützwand 14 ist mit sich quer von ihr wegerstreckenden, unter einem rechten Winkel abgebogenen Haltelaschen 15,16 versehen. Diese liegen jeweils an der Außenseite einer der Tragwände 2,3 an. Mit ihren aufeinanderzu umgebogenen Enden 17,18 stellen sie den festen Halt der Stützwand 14 am Kontaktfederträger 1 sicher.The two supporting walls 2, 3 are connected to one another via a transverse wall 12 which determines the distance between the supporting walls. On the edges 10, 11 of the supporting walls 2, 3 which are remote from the transverse wall 12, a support wall 14 is provided which delimits the insertion gap 5 for the flat contact tongue. The support wall 14 is provided with holding straps 15, 16 extending transversely from it and bent at a right angle. These are in each case on the outside of one of the supporting walls 2, 3. With their ends 17, 18 bent towards one another, they ensure that the support wall 14 is firmly held on the contact spring support 1.

Die Querwand 12 ist mit einem Ausschnitt 19 versehen, in den die umgebogenen Enden 17,18 der Haltelaschen 15,16 der Stützwand 14 eingreifen. Diese Enden 17, 18 der Haltelaschen 15,16 sind um 180° umgebogen und hintergreifen die Tragwände 2,3 jeweils an den Ausschnitt 19 angrenzend. Die von der Stirnkante 20 der Querwand 12 ausgehenden Stirnkanten der Tragwände 2,3 sind jeweils mit einer Aussparung 21,22 versehen. Diese Aussparungen beginnen dort, wo die Enden der Haltelaschen 15,16 auslaufen. Diese Aussparungen definieren jeweils denjenigen Bereich der Tragwandkanten 10,11, auf denen sich die umgebogenen Enden 6m7 der Kontaktfedern 4 abstützen.The transverse wall 12 is provided with a cutout 19, in which the bent ends 17, 18 of the retaining tabs 15, 16 of the support wall 14 engage. These ends 17, 18 of the retaining tabs 15, 16 are bent through 180 ° and engage behind the support walls 2, 3 each adjacent to the cutout 19. The end edges of the supporting walls 2, 3 starting from the end edge 20 of the transverse wall 12 are each provided with a recess 21, 22. These cutouts begin where the ends of the retaining tabs 15, 16 end. These recesses each define that area of the supporting wall edges 10, 11 on which the bent ends 6m7 of the contact springs 4 are supported.

Aus den Fig. 3 und 4 geht der Einsatz der Kontaktbuchsen bei einer Prüfkontaktsteckvorrichtung mit einem eine Mehrzahl von durchgehenden Ausnehmungen 23 für die Aufnahme und lösbare Festlegung derartiger Kontaktbuchsen aufweisenden Isolierkörper 24 hervor. Jeder Kontaktfederträger 1 ist mit mindestens einer, vorzugsweise zwei Rastzungen 25,26 versehen. Diese erstrecken sich schräg zur Achse des Einführspaltes 5 für die Flachkontaktzunge von der Außenseite des Kontaktfederträgers 1 weg. Bei Einführung in die zugehörige Ausnehmung 23 des Isolierkörpers 24 hintergreift jede Rastzunge 25,26 eine in der Ausnehmung 23 vorgesehene seitliche Rastschulter 27,28.3 and 4 show the use of the contact sockets in a test contact plug device with a plurality of continuous recesses 23 for receiving and releasably fixing such contact sockets having insulating bodies 24. Each contact spring support 1 is provided with at least one, preferably two locking tongues 25, 26. These extend obliquely to the axis of the insertion gap 5 for the flat contact tongue from the outside of the contact spring carrier 1. When inserted into the associated recess 23 of the insulating body 24, each latching tongue 25, 26 engages behind a lateral latching shoulder 27, 28 provided in the recess 23.

Aus der Zeichnung geht hervor, daß die Rastzungen 25, 26 jeweils einstückig mit einer der beiden Haltelaschen 15,16 der Stützwand 14 ausgebildet sind.From the drawing it can be seen that the latching tongues 25, 26 are each formed in one piece with one of the two retaining tabs 15, 16 of the support wall 14.

Der Kontaktfederträger 1 jeder Kontaktbuchse der Prüfkontaktsteckvorrichtung ist mit einem der Stromzuführung dienenden Anschlußvorsprung 29 versehen. Dieser geht von der die Tragwände 2,3 verbindenden Querwand 12 aus. Bei der in Fig. 1 veranschaulichten Ausführungsform ist der Anschlußvorsprung 29 mit Crimplaschen 30 versehen, die den festen Anschluß eines nicht veranschaulichten Kabels ermöglichen. Gemäß der in Fig. 2 veranschaulichten Ausführungsform kann der Anschlußvorsprung auch in Form eines etwa runden Kontaktstifts 31 ausgebildet sein. Dieser ermöglicht, wie in Fig. 3 veranschaulicht, den leicht lösbaren Anschluß eines mit einer Kontaktfederbuchse 32 verbundenen Kabels, das ebenfalls nicht gezeigt ist. Bei dieser Ausführung kann das Kabel mitsamt der Kontaktfederbuchse 32 vom Kontaktstift 31 leicht getrennt werden, um anschließend die durch häufige Benutzung verschlissene Kontaktbuchse aus der Ausnehmung 23 des Isolierkörpers 24 zu entnehmen und durch eine neue Kontaktbuchse zu ersetzen.The contact spring support 1 of each contact socket of the test contact plug device is with one of the power supply Provide connection projection 29. This starts from the transverse wall 12 connecting the supporting walls 2, 3. In the embodiment illustrated in FIG. 1, the connection protrusion 29 is provided with crimping tabs 30 which enable a cable (not illustrated) to be firmly connected. According to the embodiment illustrated in FIG. 2, the connection projection can also be designed in the form of an approximately round contact pin 31. This enables, as illustrated in Fig. 3, the easily detachable connection of a cable connected to a contact spring socket 32, which is also not shown. In this embodiment, the cable together with the contact spring socket 32 can be easily separated from the contact pin 31 in order to subsequently remove the contact socket, which has been worn through frequent use, from the recess 23 of the insulating body 24 and to replace it with a new contact socket.

Die Fig. 9 bis 13 dienen der Erläuterung des Ausführungsbeispiels nach der Erfindung. Gleiche Bezugszeichen bezeichnen gleiche Elemente. Das erfindungsgemäße Ausführungsbeispiel unterscheidet sich von dem vorstehend erläuterten dadurch, daß die Kontaktfedern 4' als einstückig mit der jeweils zugehörigen Tragwand 2',3' ausgeführte schmale Zungen gebildet sind. Gemäß Fig. 12, rechte Seite, schließen sich die Kontaktfedern 4' zurückgebogen an die Tragwand 2' an. Der mit 11' bezeichnete Übergang von der Tragwand 2' in die zungenförmige Kontaktfeder 4' ersetzt dabei die mit dem Ende 7 umlegte Kante 11 der Tragwand 2 nach der Ausführung gemäß Fig. 8. Die Kontaktfeder 4' erstreckt sich längs der Innenseite der Tragwand 2' zu deren dem Übergang 11' gegenüberliegender Kante 10'. Das freie Ende 6' der Kontaktfeder 4' ist um die Tragwandkante 10' zurückgebogen.9 to 13 serve to explain the embodiment of the invention. The same reference numerals designate the same elements. The exemplary embodiment according to the invention differs from the one explained above in that the contact springs 4 'are formed as narrow tongues made in one piece with the respectively associated supporting wall 2', 3 '. 12, right side, the contact springs 4 'are bent back to the supporting wall 2'. The transition designated 11 'from the supporting wall 2' into the tongue-shaped contact spring 4 'replaces the edge 11 of the supporting wall 2 folded over with the end 7 according to the embodiment according to FIG. 8. The contact spring 4' extends along the inside of the supporting wall 2 'to their edge 10' opposite the transition 11 '. The free end 6 'of the contact spring 4' is bent back around the edge 10 'of the supporting wall.

Fig. 13 zeigt ein Blech 33. Der in Fig. 13 obere Teil des Bleches 33 bildet bei der daraus herzustellenden Kontaktbuchse die Tragwand 2' bzw. 3'. Im unteren Teil ist durch Stanzen eine Reihe Blechstreifen ausgebildet, die als Kontaktfedern 4' dienen. Mit 19' ist ein Durchbruch entsprechend dem Ausschnitt 19 nach der vorerwähnten Ausführung bezeichnet. Das Blech 33 kann in seinem oberen, später die Tragwand 2' bzw. 3' darstellenden Teil stärker als in seinem unteren Teil sein. Dadurch können den Tragwänden die erforderliche Steifigkeit und den Kontaktfedern die erforderlichen Federeigenschaften gegeben werden, obwohl Tragwand und Kontaktfedern jeweils aus einem einzigen Blech gefertigt werden.FIG. 13 shows a sheet 33. The upper part of the sheet 33 in FIG. 13 forms the supporting wall 2 'or 3' in the contact socket to be produced therefrom. In the lower part is through Stamping a series of sheet metal strips formed, which serve as contact springs 4 '.
