Abstract

A connector for a group of insulated conductors is disclosed comprising flat contact plates (14) for contacting the conductors (7) and suitable for plugging into slots (15) in the connector's casing (1), each plate provided with three contact teeth (16) which are offset laterally with regard to each other by bevelling (30) and joined together into one piece with contact strips (21) which provide contact surfaces in a plastic component for an electric plug. Narrow intermediate strips (20), provided between the contact plates and the contact strips, create heels, by means of which the contact plates rest on the plastic component. Transitional sections (25) between the contact strips and the intermediate strips create additional heels, supported within the plastic component, whereby the bent intermediate strips-carried freely through chambers-mechanically uncouple the contact plates from the contact strips.

Description

Die Erfindung bezieht sich auf eine Anschlußvorrichtung für eine Mehrzahi von isolierten Adern, mit einem aus Isoliermaterial bestehenden Gehäuse, das einen Eingang für ein die Adern zusammenfassendes Kabel und daran anschließend eine der Zahl der Adern entsprechende Anzahl von nebeneinanderliegend vorgesehenen Aufnahmeröhren für die Adern aufweist, mit in dem Gehäuse vorgesehenen, den Aufnahmeröhren zugeordneten, zueinander parallelen Schlitzen, die mit ihren Schmalseiten auf die Aufnahmeröhren ausgerichtet sind und diese mit einer Außenseite des Gehäuses verbinden, sowie mit plättchenförmigen Kontaktstücken, die von der Außenseite des Gehäuses her unter Kontaktierung jeweils einer in einer der Aufnahmeröhren steckenden Ader in die Schlitze eindrückbar ausgebildet sind und an ihren zu den Aufnahmeröhren rechtwinkligen Kanten Widerhaken zur Verhakung der Kontaktstücke in dem Gehäuse aufweisen.The invention relates to a connecting device for a plurality of insulated wires, with a housing made of insulating material, which has an input for a cable summarizing the wires and then a number of wires corresponding to the number of wires provided next to one another provided with provided in the housing, assigned to the receiving tubes, mutually parallel slots, which are aligned with their narrow sides to the receiving tubes and connect them to an outside of the housing, as well as with plate-shaped contact pieces, each of which from the outside of the housing with contacting one in one of the Receptacle-inserting wire are designed to be pressed into the slots and have barbs at their edges perpendicular to the receiving tubes for hooking the contact pieces in the housing.

Eine solche Anschlußvorrichtung ist z. B. aus der DE-AS 24 32122 bekannt. Bei dieser bekannten Vorrichtung wird eine Kontaktgabe zwischen einem der Kontaktstücke und weiterführenden Leitungen dadurch bewerkstelligt, daß jeweils ein externes Kontaktelement mit einem Rücken eines Kontaktstückes in elastische Berührung gebracht -wird. Dabei sind besondere Vorkehrungen erforderlich, um sicherzustellen, daß das externe Kontaktelement betriebssicher den relativ schmalen Rücken des Kontaktstückes nicht verfehlt.Such a connection device is such. B. known from DE-AS 24 32122. In this known device, contact is established between one of the contact pieces and further lines by bringing an external contact element into elastic contact with a back of a contact piece. Special precautions are required to ensure that the external contact element does not fail to reliably miss the relatively narrow back of the contact piece.

Zwar ist es schon aus der DE-OS 31 32 362 bekannt, einen relativ breiten Kontaktstreifen vorzusehen, der jeweils mit einem Kontaktstück elektrisch verbunden ist, wodurch ein externes Kontaktelement relativ unkompliziert mit dem Kontaktstreifen verbunden und damit an eine von dem Kontaktstück kontaktierte Ader angeschlossen werden kann.It is already known from DE-OS 31 32 362 to provide a relatively wide contact strip, each of which is electrically connected to a contact piece, as a result of which an external contact element is connected to the contact strip in a relatively uncomplicated manner and is thus connected to a wire contacted by the contact piece can.

Demgegenüber ist es Aufgabe vorliegender Erfindung, eine Anschlußvorrichtung der eingangs genannten Art so weiterzubilden, daß bei unkompliziertem Aufbau der Vorrichtung sowohl die Kontaktstücke betriebssicher mit den Adern verbindbar sind, als auch einstückig mit den Kontaktstücken zusammenhängende Kontaktstreifen geschaffen werden, die mit einem externen Kontaktelement unkompliziert elektrisch verbunden werden können.In contrast, it is an object of the present invention to further develop a connection device of the type mentioned in such a way that, with an uncomplicated construction of the device, both the contact pieces can be reliably connected to the wires, and contact strips which are integrally connected to the contact pieces and which are easily electrically connected to an external contact element are created can be connected.

Erfindungsgemäß ist zur Lösung dieser Aufgabe vorgesehen, daß jedes Kontaktstück in Verlaufsrichtung einer Ader drei Kontaktierspitzen aufweist, mit lediglich durch Anschrägungen zueinander querversetzten freien Enden der Kontaktierspitzen, daß in einem auf der Seite der äußeren Schlitzmündungen mit dem Gehäuse verrastbaren Kunststoffkörper in diesen Körper von der dem Gehäuse zugewandten Seite des Körpers her einschiebbare, zungenförmige Kontaktabschnitte vorgesehen sind, die über einen Steg, der eine geringere Breite als die Kontaktstücke und die Kontaktabschnitte aufweist, einstückig mit den Kontaktstücken zusammenhängen und in einer zur Ebene der Kontaktstücke parallelen Ebene in dem Kunststoffkörper angeordnet sind, und daß die Kontaktstücke mit zwischen den Kontaktstücken und den Stegen vorgesehenen Schultern an dem Kunststoffkörper abgestützt sind.According to the invention it is provided to solve this problem that each contact piece has three contacting tips in the direction of travel of a wire, with free ends of the contacting tips which are only crosswise offset by bevels, that in a plastic body which can be locked with the housing on the side of the outer slot openings in this body by the Insertable, tongue-shaped contact sections are provided on the housing-facing side of the body and are integrally connected to the contact pieces via a web that has a smaller width than the contact pieces and the contact sections and are arranged in a plane parallel to the level of the contact pieces in the plastic body, and that the contact pieces are supported on the plastic body with shoulders provided between the contact pieces and the webs.

Auf diese Weise zwingen die in eine Ader eindringenden Kontaktierspitzen eines Kontaktstückes dieser einen mäanderförmigen Verlauf auf, wodurch sich zwischen Kanten der Kontaktierspitzen und einer Ader Stellen mit grosser Flächenpressung ergeben und dadurch eine sichere Kontaktgabe zwischen den Kontaktstücken und den Adern bewirkt wird. Außerdem wird mit dem Kunststoffkörper, der mit dem Isolierstoffgehäuse der Vorrichtung verrastbar ausgebildet ist, ein Hilfsorgan bereitgestellt, mit dem die Kontaktstücke unkompliziert in die Gehäuseschlitze zur Kontaktierung der Adern eingedrückt werden können.In this way, the contacting tips of a contact piece penetrating into a wire force it onto a meandering course, as a result of which points with high surface pressure arise between the edges of the contact tips and a wire, thereby ensuring reliable contact between the contact pieces and the wires. In addition, an auxiliary element is provided with the plastic body, which can be locked with the insulating material housing of the device, with which the contact pieces can be easily pressed into the housing slots for contacting the wires.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß die dem Kunststoffkörper zugewandten Schultern der Kontaktstücke und diesen Schultern zugewandte Auflageflächen des Kunststoffkörpers eine solche Bemessung aufweisen, daß die Kontaktstücke geringfügig in das Material des Kunststoffkörpers eindrückbar sind.In a further embodiment of the invention it can be provided that the shoulders of the contact pieces facing the plastic body and support surfaces of the plastic body facing these shoulders are dimensioned such that the contact pieces can be pressed slightly into the material of the plastic body.

Hierdurch ist es möglich, daß die Kontaktstücke etwas nachgeben können, wenn z. B. aus einem Volldraht bestehende Adern zu kontaktieren sind, wodurch die Vorrichtung sich in gewisser Weise auf unterschiedlich aufgebaute Adern einstellen kann und in jedem Fall eine betriebssichere Kontaktierung zwischen den Kontaktstücken und den Adern erzielt wird.This makes it possible for the contact pieces to yield somewhat if, for. B. are to be contacted from a solid wire, whereby the device can adjust to a certain extent on differently constructed wires and in any case reliable contact between the contact pieces and the wires is achieved.

Ferner kann vorgesehen sein, daß die Stege einen gekrümmten Verlauf aufweisen und in Kammern des Kunststoffkörpers frei geführt sind und daß zwischen jedem Kontaktabschnitt und jedem Steg ein gegenüber dem Kontaktabschnitt breiterer Übergangsabschnitt unter Bildung von an dem Kunststoffkörper abgestützten Schultern des Übergangsabschnittes vorgesehen ist.Furthermore, it can be provided that the webs have a curved course and are freely guided in chambers of the plastic body and that between each contact section and each web a transitional section is provided which is wider than the contact section, forming shoulders of the transition section supported on the plastic body.

Bei geeigneter Bemessung des gekrümmten Verlaufes kann hierdurch ein Kraftspeicher gebildet werden, der die Kontaktierwirkung der Kontaktstücke konstant hält. Außerdem dient der gekrümmte Verlauf der Stege zur Entkopplung der Kontaktabschnitte gegenüber den Kontaktstücken, so daß z. B. auf die Kontaktabschnitte einwirkende Vibrationen sich nicht ohne weiteres auf die Kontaktstücke und damit auf die Kontaktgabe zwischen den Kontaktstücken und den Adern auswirken können.With a suitable dimensioning of the curved course, a force accumulator can be formed which keeps the contacting effect of the contact pieces constant. In addition, the curved course of the webs serves to decouple the contact sections relative to the contact pieces, so that, for. B. vibrations acting on the contact sections can not easily affect the contact pieces and thus on the contact between the contact pieces and the wires.

Schließlich kann noch vorgesehen sein, daß das Gehäuse in einem vom Kabel-Eingang abgewandten Endbereich der Aufnahmeröhren zumindest auf einer Seite der Aufnahmeröhren eine mit der Außenseite des Gehäuses verbundene und rechtwinkelig zum Verlauf der Aufnahmeröhren sich erstreckende fensterartige Ausnehmung aufweist.Finally, it can also be provided that the housing in an end region of the receiving tubes facing away from the cable entrance has a window-like recess connected to the outside of the housing and extending at right angles to the course of the receiving tubes, at least on one side of the receiving tubes points.

Dadurch wird ein Beobachtungsfenster gebildet, das es ermöglicht, unkompliziert festzustellen, ob die Adern weit genug in die Aufnahmeröhren des Gehäuses eingeschoben sind.This creates an observation window, which makes it easy to determine whether the wires are inserted far enough into the receiving tubes of the housing.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand von fünf Figuren noch näher erläutert.An embodiment of the invention is explained in more detail below with reference to five figures.

Dabei zeigen, jeweils stark vergrößert, und im Schnitt,

  • Fig. 1 eine Ansicht der Vorrichtung von oben gesehen,
  • Fig. 2 eine Seitenansicht der Vorrichtung,
  • Fig. 3 und Fig.4 Querschnitte der Vorrichtung und
  • Fig. 5 die Kontaktierung einer Ader durch ein Kontaktstück.
Here show, each greatly enlarged, and on average,
  • 1 is a view of the device seen from above,
  • 2 is a side view of the device,
  • Fig. 3 and Fig.4 cross sections of the device and
  • Fig. 5, the contacting of a wire through a contact piece.

Im einzelnen ist den Figuren zu entnehmen, daß die Vorrichtung ein längliches Kunststoffgehäuse 1 aufweist mit einer Stirnseite 2 und Längsseiten 3. Auf seiner, der Stirnseite 2 gegenüberliegenden Seite 4 ist das Gehäuse mit einer Eingangsöffnung 5 für ein Kabel 6 versehen. Bei dem Kabel 6 handelt er sich vorzugsweise um die Anschlußschnur eines Telefonapparates. Hierbei sind vier jeweils für sich von einer isolierenden Umhüllung umgebene Adern 7 in einer gemeinsamen Isolierstoffhülle nebeneinanderliegend angeordnet.In detail, it can be seen from the figures that the device has an elongated plastic housing 1 with an end face 2 and longitudinal sides 3. On its side 4 opposite the end face 2, the housing is provided with an inlet opening 5 for a cable 6. The cable 6 is preferably the connecting cord of a telephone set. Here, four wires 7, each surrounded by an insulating sheath, are arranged next to one another in a common insulating material sheath.

Vor dem Einschieben des Kabels 6 in die Eingangsöffnung 5 des Gehäuses 1 ist die gemeinsame Hülle der Adern 7 in einem Endabschnitt des Kabels 6 entfernt worden, wobei der Endabschnitt der Länge von Aufnahmeröhren 8 angepaßt ist, die für jeweils eine der Adern 7 nebeneinander in Fortsetzung der Eingangsöffnung 5 im Gehäuse 1 zwischen der Stirnseite 2 und der Seite 4 parallel zur Längsachse des Gehäuses vorgesehen sind.Before the cable 6 is inserted into the input opening 5 of the housing 1, the common sheath of the wires 7 in an end section of the cable 6 has been removed, the end section being adapted to the length of receiving tubes 8, which are continued for one of the wires 7 next to one another the input opening 5 in the housing 1 between the end face 2 and the side 4 are provided parallel to the longitudinal axis of the housing.

Im Bereich der Eingangsöffnung 5 sind von der Eingangsöffnung 5 ausgehend die Eingangsöffnung 5 abschnittweise vergrößernde seitliche Nischen 10 vorgesehen. Außerdem ist die Eingangsöffnung 5 mit solchen Abmessungen versehen, daß zwischen den Wänden des Gehäuses 1 und dem Kabel 6 im Bereich der Eingangsöffnung 5 ein Abstand verbleibt, der mit Kunstharz vergossen werden kann. Dabei dienen die Nischen 10 zur Verankerung der aushärtenden Kunstharzmasse 11 und fangen damit auf das Kabel 6 einwirkende Zugkräfte, die das Kabel 6 wieder aus dem Gehäuse 1 herausziehen wollen, ab.In the area of the inlet opening 5, starting from the inlet opening 5, lateral niches 10 are provided which enlarge the inlet opening 5 in sections. In addition, the input opening 5 is provided with dimensions such that a distance remains between the walls of the housing 1 and the cable 6 in the region of the input opening 5, which can be potted with synthetic resin. The niches 10 serve to anchor the hardening synthetic resin composition 11 and thus absorb tensile forces acting on the cable 6, which want to pull the cable 6 out of the housing 1.

Auf einer Oberseite 12 ist das Gehäuse 1 bis auf eine fensterartige Ausnehmung 9 geschlossen ausgebildet. Die fensterartige Ausnehmung 9 reicht von der Seite 12 bis zu einem von der Eingangsöffnung 5 abgewandten Endbereich der Aufnahmeröhren 8 für die Adern 7 und wird nach der Montage und dem Anschluß der Adern 7 ebenfalls vergossen und damit verschlossen. Durch die Ausnehmung 9 kann die richtige Lage der Adern 7 in den Aufnahmeröhren 8 beobachtet werden.On an upper side 12, the housing 1 is closed except for a window-like recess 9. The window-like recess 9 extends from the side 12 to an end region of the receiving tubes 8 for the wires 7 facing away from the input opening 5 and is also cast and closed after the assembly and connection of the wires 7. The correct position of the wires 7 in the receiving tubes 8 can be observed through the recess 9.

Auf der von der Oberseite 12 abgewandten Seite ist das Gehäuse 1 mit einer Aufnahmekontur für einen Kunststoffkörper 13 versehen, der mit dem Gehäuse 1 verrastbar ausgebildet ist.On the side facing away from the upper side 12, the housing 1 is provided with a receiving contour for a plastic body 13 which is designed to be latchable with the housing 1.

Bei der Verrastung des Isoiierstoffkörpers 13 mit dem Gehäuse 1 durchsetzen plättchenförmige Kontaktstücke 14, die frei vom Isolierstoffkörper 13 abstehen, Schlitze 15 (Fig. 1), die im Gehäuse 1 zwischen den Aufnahmeröhren 8 und der von der Seite 12 des Gehäuses 1 abgewandten Seite des Gehäuses 1 vorgesehen sind. Die Schlitze 15 sind jeweils auf eine der Aufnahmeröhren 8 ausgerichtet, so daß ein Kontaktstück 14 durch einen solchen Schlitz 15 hindurch mit Kontaktierspitzen 16 in eine Aufnahmeröhre 8 eindringen kann. Jedes Kontaktstück 14 weist drei solche Kontaktierspitzen 16 auf, die in Verlaufsrichtung einer Aufnahmeröhre 8 hintereinander angeordnet sind. Die freien Enden der Kontaktierspitzen 16 sind dabei lediglich durch Abschrägungen 30 gegeneinander so versetzt, daß die freien Enden der beiden äußeren Kontaktierspitzen etwas links und das freie Ende der mittleren Kontaktierspitze etwas rechts von der Achse einer Aufnahmeröhre 8 vorhanden ist. Demzufolge zwingen die Kontaktierspitzen 16 eines Kontaktstückes einer in einer Aufnahmeröhre 8 steckenden Ader 7 einen geringfügig mäanderförmigen Verlauf auf, wenn sie in diese Ader eindringen. Die Kontaktsicherheit zwischen leitenden Teilen der Ader 7 und einem Kontaktstück 14 wird dadurch wesentlich verbessert.When the Isoiierstoffkörper 13 with the housing 1 penetrate platelet-shaped contact pieces 14, which protrude freely from the insulating body 13, slots 15 (Fig. 1), which are in the housing 1 between the receiving tubes 8 and the side facing away from the side 12 of the housing 1 Housing 1 are provided. The slots 15 are each aligned with one of the receiving tubes 8, so that a contact piece 14 can penetrate through such a slot 15 with contacting tips 16 into a receiving tube 8. Each contact piece 14 has three such contact tips 16, which are arranged one behind the other in the direction of travel of a receiving tube 8. The free ends of the contact tips 16 are offset from one another only by bevels 30 such that the free ends of the two outer contact tips are somewhat to the left and the free end of the central contact tip is somewhat to the right of the axis of a receiving tube 8. As a result, the contact tips 16 of a contact piece of a wire 7 inserted in a receiving tube 8 force a slightly meandering course when they penetrate into this wire. The contact security between conductive parts of the wire 7 and a contact piece 14 is significantly improved.

An ihren Rändern 17, die den Schmalseiten der Schlitze 15 zugewandt sind, weisen die Kontaktstücke Widerhaken auf, die beim Eindrücken der Kontaktstücke in die Schlitze 15 in das Kunststoffmaterial des Gehäuses 1 eingepreßt werden und dadurch die Kontaktstücke 14 im Gehäuse 1 verriegeln.At their edges 17, which face the narrow sides of the slots 15, the contact pieces have barbs which are pressed into the plastic material of the housing 1 when the contact pieces are pressed into the slots 15 and thereby lock the contact pieces 14 in the housing 1.

Die Kontaktstücke 14 sitzen mit Schultern 19 auf einer Oberfläche des Kunststoffkörpers 13. Dabei sind die Schultern 19 und die mit diesen Schultern 19 in Berührung kommenden Oberflächenbereiche des Kunststoffkörpers 13 so aufeinander abgestimmt, daß sich die Kontaktstücke 14 geringfügig in die Kunststoffmasse des Kunststoffkörpers 13 eindrücken können, wenn der Widerstand, den eine Ader 7 dem Eindringen der Kontaktierspitzen 16 entgegensetzt, ein bestimmtes Ausmaß übersteigt.The contact pieces 14 sit with shoulders 19 on a surface of the plastic body 13. The shoulders 19 and the surface areas of the plastic body 13 which come into contact with these shoulders 19 are matched to one another in such a way that the contact pieces 14 can be pressed slightly into the plastic mass of the plastic body 13 , when the resistance that a wire 7 opposes to the penetration of the contact tips 16 exceeds a certain level.

Die Schultern 19 der Kontaktstücke 14 werden dadurch gebildet, daß die Kontaktstücke 14 lediglich über schmale Stege 20 mit Kontaktabschnitten 21 zusammenhängen. Die zungenförmigen Kontaktabschnitte 21 sind in Führungsnuten 22 des Kunststoffkörpers 13 derart eingeschoben, daß ein mittlerer Bereich 23 der Kontaktabschnitte freiliegt. Mit diesen mittleren Bereichen 23 der Kontaktabschnitte 21 können daher unkompliziert externe Kontaktorgane in Verbindung gebracht werden, z. B. ortsfest vorgesehene Kontaktfedern eines Gehäuses, in das der Kunststoffkörper 13 mit dem Bereich eingesteckt werden kann. in dem sich die Kontaktabschnitte 21 befinden.The shoulders 19 of the contact pieces 14 are formed in that the contact pieces 14 are connected to contact sections 21 only via narrow webs 20. The tongue-shaped contact sections 21 are inserted into guide grooves 22 of the plastic body 13 in such a way that a central region 23 of the contact sections is exposed. With these central regions 23 of the contact sections 21, external contact members can therefore be easily connected, for. B. fixedly provided contact springs of a housing into which the plastic body 13 can be inserted with the area. in which the contact sections 21 are located.

Die Breite der zungenförmigen Kontaktabschnitte 21 ist geringer bemessen als die Breite der Kontaktstücke 14. Dadurch können die Kontaktabschnitte 21 von der Seite her in den Kunststoffkörper 13 eingeschoben werden, von der die Kontaktstücke 14 abstehen. Übergangsabschnitte 24, die zwischen den Stegen 20 und den Kontaktabschnitten 21 vorgesehen sind und eine größere Breite als die Kontaktabschnitte 21, jedoch eine geringere Breite als die Kontaktstücke 14 aufweisen, bilden Schultern, die sich an entsprechenden Kanten des Kunststoffkörpers 13 abstützen und den Einschubweg der Kontaktabschnitte 21 begrenzen. Die freien Enden 25 der Kontaktabschnitte 21 sind um Kanten des Kunststoffkörpers 13 herum abgebogen und halten dadurch die Kontaktabschnitte 21 entgegengesetzt zur Einschubrichtung im Kunststoffkörper 13 fest. Die Stege 20 verlaufen zwischen den Übergangsabschnitten 24 und den Kontaktstücken 14 gekrümmt und frei geführt in Kammern 26 des Kunststoffkörpers 13 und tragen dadurch zur mechanischen Entkopplung der Kontaktstücke 14 und der Kontaktabschnitte 21 bei. Insbesondere kann sich dadurch eine Bewegung der Kontaktstücke 14 beim Eindrücken dieser Kontaktstücke in die Schlitze 15, wobei die Kontaktstücke 14 mit ihren Schultern 19 gegen den Kunststoffkörper 13 gepreßt werden, nicht auf die Kontaktabschnitte 21 auswirken.The width of the tongue-shaped contact sections 21 is smaller than the width of the contact pieces 14 Clock sections 21 are inserted from the side into the plastic body 13 from which the contact pieces 14 protrude. Transitional sections 24, which are provided between the webs 20 and the contact sections 21 and have a greater width than the contact sections 21, but a smaller width than the contact pieces 14, form shoulders which are supported on corresponding edges of the plastic body 13 and the insertion path of the contact sections Limit 21. The free ends 25 of the contact sections 21 are bent around edges of the plastic body 13 and thereby hold the contact sections 21 in the plastic body 13 opposite to the insertion direction. The webs 20 run between the transition sections 24 and the contact pieces 14 in a curved and freely guided manner in chambers 26 of the plastic body 13 and thereby contribute to the mechanical decoupling of the contact pieces 14 and the contact sections 21. In particular, a movement of the contact pieces 14 when these contact pieces are pressed into the slots 15, the contact pieces 14 with their shoulders 19 being pressed against the plastic body 13, does not affect the contact sections 21.

Beim Zusammenfügen des Kunststoffkörpers 13 mit dem Gehäuse 1 dringen durch entsprechend vorgesehene Kanäle des Gehäuses 1 Abfangdorne 29 bzw. Abfangbolzen 27, die einstückig mit dem Künststoffkörper 13 ausgebildet sind, in den Mantel des Kabels 6 bzw. einer Ader 7 ein und sichern diese in das Gehäuse 1 eingesteckten Teile davor, wieder aus dem Gehäuse 1 herausgezogen zu werden. Dadurch werden die Kontaktstellen zwischen den Kontaktierungspitzen 16 und den leitenden Teilen der Adern 7 mechanisch entlastet.When assembling the plastic body 13 with the housing 1 penetrate through appropriately provided channels of the housing 1 intercepting pins 29 or intercepting bolts 27, which are formed in one piece with the plastic body 13, into the jacket of the cable 6 or a wire 7 and secure this in the Housing 1 inserted parts from being pulled out of the housing 1 again. As a result, the contact points between the contacting tips 16 and the conductive parts of the wires 7 are mechanically relieved.

Erst nach der Vereinigung des Gehäuses 1 mit dem Kunststoffkörper 13 wird die Eingangsöffnung 5 mit Kunstharz vergossen und dadurch das Kabel 6 endgültig am Gehäuse 1 festgelegt.Only after the housing 1 has been combined with the plastic body 13 is the inlet opening 5 potted with synthetic resin and the cable 6 is thereby finally fixed to the housing 1.

Ein mit dem Kunststoffkörper 13 einstückiger elastisch gegen den Kunststoffkörper 13 federnder Hebel 28, der mit entsprechenden Gegenkonturen eines Aufnahmegehäuses für die Vorrichtung zusammenwirkt, hält die Vorrichtung im Aufnahmegehäuse fest.A lever 28, which is integral with the plastic body 13 and resiliently resilient against the plastic body 13 and which interacts with corresponding counter-contours of a receiving housing for the device, holds the device in place in the receiving housing.
