Description

mit den Hülsen Kontakt bilden soll, ist A, und die Achsen der Stifte haben voneinander einen Abstand B. Dadurch, daß die beiden Hülsen in dem Block 10 in bezug aufeinander so angeordnet sind, daß die Hauptteile 2 der Hülse, die von der nach innen eingebogenen und den Federteil 6 bildenden Kante nicht überdeckt sind, einander zugewendet sind, haben die Hülsen in bezug auf den Mittelpunkt ihres Einsteckraums 9 den Abstand B voneinander, und dieser Abstand S entspricht dem Abstand der Achsen der Steckerstifte, ungeachtet der Tatsache, daß die geometrischen Mittelpunkte der Hülsen 1 einen Abstand C voneinander haben, der größer ist als der Abstand B. to make contact with the sleeves is A, and the axes of the pins are spaced from one another B. By virtue of the fact that the two sleeves in the block 10 are arranged with respect to one another in such a way that the main parts 2 of the sleeve, which are inwardly from the bent and the spring part 6 forming edge are not covered, are facing each other, the sleeves have a distance B from each other with respect to the center of their insertion space 9, and this distance S corresponds to the distance between the axes of the connector pins, regardless of the fact that the geometric Centers of the sleeves 1 have a distance C from one another which is greater than the distance B.

Die F i g. 3 und 4 zeigen eine abgewandelte Ausführungsform der Anordnung gemäß F i g. 1. Der Unterschied liegt darin, daß der Anschlußdraht direkt mit der Hülse und nicht über eine angesetzte Zwinge über einen Fortsatz 8 verbunden ist, vielmehr eine Längsnut 11 an dem Teil Anwendung findet, der hinter der Kontaktfeder 6 liegt. Diese Nut wird bei der Herstellung der Hülse eingepreßt und hat eine nach außen gerichtete Rippe 12 an der Außenseite zur Folge. Um einen Draht 13 mit der Hülse 1 zu verbinden, wird der Draht in die Nut 11 so eingeführt, daß er in der Nut und dem Raum 14 hinter dem Federteil 6 liegt. Wenn ein Steckerstift 5 in den Raum 9 eingeführt wird, so wird der Federteil 6 durchgebogen, und es verriegelt sich der Anschlußdraht fest in dem Raumteil 14. Der Federteil 6 hat daher zwei Funktionen, nämlich die Funktion, den Draht zu befestigen und Kontakt mit dem Kontaktstecker zu bilden. Damit die Federungseigenschaften des Federteils 6 entsprechend eingestellt sein können, ist zwischen dem Teil 3 und dem Federteil 6 der Verbindungsteil durch einen Schlitz 17 teilweise geschwächt, wobei der Schlitz 17 sich in Längsrichtung der Kontakthülse erstreckt.The F i g. 3 and 4 show a modified embodiment of the arrangement according to FIG. 1. The The difference is that the connecting wire connects directly to the sleeve and not via an attached one Ferrule is connected via an extension 8, rather a longitudinal groove 11 is used on the part that is behind the contact spring 6. This groove is pressed in during the manufacture of the sleeve and has a result in outwardly directed rib 12 on the outside. To a wire 13 with the sleeve 1 too connect, the wire is inserted into the groove 11 so that it is in the groove and the space 14 behind the spring part 6 lies. When a connector pin 5 is inserted into the space 9, the spring part 6 becomes bent, and it locks the connecting wire firmly in the space part 14. The spring part 6 has hence two functions, namely the function of securing the wire and making contact with the contact plug to build. So that the suspension properties of the spring part 6 can be adjusted accordingly, the connecting part is partially weakened by a slot 17 between the part 3 and the spring part 6, wherein the slot 17 extends in the longitudinal direction of the contact sleeve.

Die F i g. 5 bis 7 zeigen eine weitere Abänderung der in F i g. 3 dargestellten Ausführungsform. Der Teil der Hülse, von dem der Federteil ausgeht, istThe F i g. 5 to 7 show a further modification of the FIG. 3 illustrated embodiment. Of the Part of the sleeve from which the spring part extends

ίο bei 18 geschlitzt, so daß am Mantel zwei Teile 19 und 20 gebildet sind, die den Anschluß von Drähten 21 und 22 unterschiedlichen Durchmessers gestatten. Ein Draht 21 größeren Durchmessers wird zwischen dem Mantelteil 19 und dem Federteil 6 eingeschlossen, während ein Draht 22 geringeren Durchmessers zwischen dem Mantelteil 20 und dem Federteil 6 eingeschlossen wird. Um das Einstecken der Drähte zu erleichtern, öffnen sich an den Enden die zur Aufnahme der Drähte vorgesehenen Teile bei 24 und 25 trichterförmig.ίο slotted at 18 so that two parts 19 and 20 are formed, which allow the connection of wires 21 and 22 of different diameters. A wire 21 of larger diameter is enclosed between the jacket part 19 and the spring part 6, while a wire 22 of smaller diameter is enclosed between the jacket part 20 and the spring part 6 will. To make it easier to insert the wires, the ends open to accommodate the wires of the wires provided parts at 24 and 25 in a funnel shape.

Wenn ein Draht 22 von verhältnismäßig geringem Durchmesser in den hinteren Teil 20 eingesteckt wird, kann der Isoliermantel innerhalb des vorderen Mantelteils 19 liegen. Dadurch ergibt sich eine Vergrößerung der zum Herausziehen des Anschlußdrahts erforderlichen Kraft.When a wire 22 of relatively small diameter is inserted into the rear part 20, the insulating jacket can lie within the front jacket part 19. This results in an enlargement the force required to pull out the lead wire.

Um die zum Herausziehen erforderliche Kraft zu vergrößern, können Quernuten an den Mantelteilen 19 und 20 vorgesehen sein. Die zwei Steckerstifte 15 der Fig.5 sind an einem Streifen26 eines Doppelsteckers angeordnet und wirken mit einer Doppelsteckhülse gemäß F i g. 2 zusammen.In order to increase the force required to pull it out, transverse grooves can be made on the casing parts 19 and 20 may be provided. The two connector pins 15 of FIG. 5 are on a strip 26 of a double connector arranged and act with a double socket according to FIG. 2 together.
