The support projections 11 support the sections 12 according to the from the middle section 13 facing away.

Die hochgestellten Abschnitte 12 besitzen einen sich in ihrer Längsrichtung erstreckenden Schlitz 14, der nach oben hin in einem Einführmaul für einen quer zur Längsrichtung des Stößels 7 einlegbaren, isolierten Zuleitungsdraht 15 endet. Der hochgestellte Abschnitt 12 wird durch den Schlitz 14 in zwei Schenkel geteilt.The raised sections 12 have one in their longitudinal direction extending slot 14 which is upward in an insertion mouth for a transverse to Longitudinal direction of the plunger 7 insertable insulated lead wire 15 ends. The Superscript section 12 is divided by the slot 14 into two legs.

Die Stützvorsprünge 11 besitzen zu den Schlitzen 14 parallele Schlitze 16 mit einer Breite wenig größer als der Durchmesser eines isolierten Zuleitungsdrahtes 15, während die Breite der Schlitze 14 etwas geringer als der Durchmesser des Zuleitungsdrahtes selbst ist, so daß die den Schlitz 14 bildenden Schenkel als Schneiden dienen, die die Isolierung des Zuleitungsdrahtes 15 durchtrennen und den Zuleitungsdraht selbst durch Einklemmen elektrisch kontaktieren.The support projections 11 have slots 16 parallel to the slots 14 a width slightly larger than the diameter of an insulated lead wire 15, while the width of the slots 14 is slightly less than the diameter of the Lead wire itself, so that the legs forming the slot 14 as Serve cutting that cut through the insulation of the lead wire 15 and make electrical contact with the lead wire by pinching it.

Die Stützvorsprünge 11 sind zweckmäßigerweise mit mindestens einer beweglichen Zunge 17 sowie eintrittsseitig zum Schlitz 16 mit diesen verengenden Vorsprüngen 18 versehen, so daß ein Hinterschnitt gebildet wird und ein eingelegter isolierter Zuleitungsdraht 15 hiervon in dieser Position gehalten wird und nicht zurückspringt bzw. herausfällt.The support projections 11 are expediently provided with at least one movable tongue 17 and on the entry side to the slot 16 with these narrowing Provide projections 18 so that an undercut is formed and an inserted insulated lead wire 15 is held in this position and not jumps back or falls out.

Die Stützvorsprünge 11 sind zweckmäßigerweise in Draufsicht L-förmig ausgebildet und insgesamt kreuzförmig angeordnet, um mit entsprechenden Gehäusewandungen bzw. -vorsprüngen im wesentlichen rechteckige Aufnahmebereiche bzw. Aussparungen für die Mittelabschnitte 13 der Kontakte 9 zu bilden.The support projections 11 are expediently L-shaped in plan view trained and arranged in a cross shape overall to correspond with Housing walls or projections essentially rectangular Receiving areas or recesses for the central sections 13 of the contacts 9 form.

Am Zwischenboden 10 befinden sich benachbart zu der Stirnseite des Gehäuses 1, an der sich die Durchtrittsöffnung 5 befindet, ein Paar von beabstandeten im wesentlichen L-förmigen Bügeln 19, deren freie Schenkel zur benachbarten Gehäusewandung gerichtet sind und an diese angrenzen, so daß zwischen dieser Gehäusewandung und den Bügeln 19 ein Langloch 20 gebildet wird.On the intermediate floor 10 are adjacent to the front of the Housing 1, on which the passage opening 5 is located, a pair of spaced substantially L-shaped brackets 19, the free legs for are adjacent to the housing wall and adjoin them, so that an elongated hole 20 is formed between this housing wall and the brackets 19 becomes.

In die Langlöcher 20 ist ein Eindrückhebel 21 mittels Vorsprüngen 22 an einem gabelförmigen Fortsatz 23 einschnappend eingehängt, so daß der gabelförmigen Fortsatz 23 mit den Bügeln 19 ein Gelenk für den Eindrückhebel 21 bildet. Wegen der Langlöcher 20 ist der Eindrückhebel 21 in dem Gelenk hochziehbar, so daß er mit einer Stirnseite 24 auf das Gehäuse 1 aufsetzbar ist und hierdurch in seiner geöffneten Stellung gehalten wird. Dadurch wird die Montage der Zuleitungsdrähte 14 erleichtert.An indentation lever 21 is in the elongated holes 20 by means of projections 22 a fork-shaped extension 23 hooked, so that the fork-shaped extension 23 with the brackets 19 a joint for the push-in lever 21 forms. Because of the elongated holes 20, the push-in lever 21 is in the joint can be pulled up so that it can be placed with an end face 24 on the housing 1 and hereby held in its open position. This will assemble the Lead wires 14 facilitated.

Der Eindrückhebel 21 ist als ein das Gehäuse 1 an seiner Breitseite verschließender Zwischendeckel ausgebildet und besitzt eine im wesentlichen umlaufende Wandung 25, die in die Öffnung des Gehäuses 1 paßt.The push-in lever 21 is a housing 1 on its broad side closing intermediate cover is formed and has an essentially circumferential wall 25 which fits into the opening of the housing 1.

An seiner Unterseite besitzt der Eindrückhebel 21 Stege 26, die beim Schließen des Eindrückhebels 21 die über den Schlitzen 14 befindlichen isolierten Zuleitungsdrähte 15 in die Schlitze 14 zwecks elektrischer Kontaktierung drücken. Dementsprechend besitzen die Stege 26 ein Breite im wesentlichen entsprechend derjenigen der Schlitze 14.On its underside, the push-in lever 21 has webs 26 which, when Closing the push-in lever 21 the insulated located over the slots 14 Press lead wires 15 into the slots 14 for electrical contact. Accordingly, the webs 26 have a width corresponding substantially that of the slots 14.

Zweckmäßigerweise sind die Stege 26 T-förmig, wobei die dadurch gebildeten Querschenkel dazu dienen, auf die isolierten Zuleitungsdrähte 15 auf der Seite der Stützvorsprünge 11 abzustützen, von der die Zuleitungsdrähte 15 in deren Schlitze 16 eingeführt sind.The webs 26 are expediently T-shaped, with the result that Cross legs formed serve on the insulated lead wires 15 on the Support side of the projections 11, from which the lead wires 15 in the Slots 16 are inserted.

Dadurch, daß die Schneidkontakte paarweise in Längsrichtung des Stößels 7 in dem Gehäuse 1 angeordnet sind und der Eindrückhebel 21 am Gehäuse 1 schwenkbar angelenkt ist, erfolgt die Kontaktierung paarweise nacheinander, so daß die Kontaktierung ohne zusätzliche Hilfsmittel über ein Eindrücken des Eindrückhebels 21 sicher vorgenommen werden kann.The fact that the cutting contacts in pairs in the longitudinal direction of the plunger 7 are arranged in the housing 1 and the push-in lever 21 on the housing 1 is pivotally articulated, the contact is made in pairs one after the other, so that the contacting without additional aids by pressing the Insertion lever 21 can be made safely.

Ferner besitzt der Eindrückhebel 21 des dargestellten Ausführungsbeispiels benachbart zu den T-förmigen Stegen 26 wenigstens jeweils eine Haltezunge 27, die beim Eindrücken des Eindrückhebels 21 den hochgestellten Abschnitt 12 und Mittelabschnitt 13 des jeweiligen Kontakts 9 abstützt, so daß dieser sich durch die Kontaktierung nicht verbiegt. Hierbei sind bei dem dargestellten Ausführungsbeispiel benachbart zum Gelenk des Eindrückhebels 21 jeweils zwei in Längsrichtung des Stößels 7 beabstandete Haltezungen 27 vorgesehen, während für das weitere Paar von Kontakten 9 jeweils eine Haltezungen 27 und ein Vorsprung 28 zum Niederhalten der Mittelabschnitte 13 der Kontakte 9 vorgesehen sind.Furthermore, the push-in lever 21 of the illustrated embodiment has adjacent to the T-shaped webs 26 at least one holding tongue 27, which when pushing in the push lever 21, the raised portion 12 and Midsection 13 of the respective contact 9 is supported, so that this through the Contact is not bent. Here are shown in the Embodiment adjacent to the joint of the indentation lever 21 in each case two Longitudinal direction of the plunger 7 spaced holding tongues 27 is provided, while for the further pair of contacts 9 a holding tabs 27 and a Projection 28 for holding down the middle sections 13 of the contacts 9 is provided are.

Hier dienen aufeinander zu gerichtete Endabschnitte 29 der Vorsprünge 28 zum Zentrieren und Bündeln der durch die Durchführungsöffnung 2 eingeführten, isolierten Zuleitungsdrähte 15.Here, end sections 29 of the projections 28 are directed towards each other for centering and bundling the inserted through the through opening 2, insulated lead wires 15.

Die Vorsprünge 28 bilden außerdem mit einer an der dem angelenkten Ende des Eindrückhebels 21 abgewandten Seite befindlichen Stirnwandung 30 eine Kammer zur Aufnahme eines Endes eines entsprechenden Zuleitungsdrahtes 15, so dieser, wenn ein metallisch abgeschirmtes Kabel 3 verwendet wird, nicht mit der metallischen Abschirmung in Kontakt gelangen kann.The projections 28 also form one at the articulated end of the insertion lever 21 facing away from the end wall 30 a Chamber for receiving one end of a corresponding lead wire 15, so this, if a metal shielded cable 3 is used, not with the metallic shield can come into contact.

Zur Montage des Zuleitungskabels 3 wird die äußere Isolierung des Zuleitungskabels 3 auf einer Länge abgemantelt, die der benötigten Maximallänge der dadurch freigelegten, isolierten Zuleitungsdrähte 15 entspricht. Zwei isolierte Zuleitungsdrähte 15 werden mit L-förmig abgebogenen Enden in die Schlitze 16 der Stützvorsprüngen 11 und das jeweilige Einführmaul der Schlitze 14 eingelegt. die beiden weiteren isolierten Zuleitungsdrähte 14 werden im wesentlichen U-förmig gebogen und ebenso eingelegt. Durch das U-förmige Biegen wird die Überlänge dieser Zuleitungsdrähte 15 kompensiert und von Gehäuse 1 aufgenommen, ohne daß es nötig ist, diese Zuleitungsdrähte 15 kürzer als die beiden anderen abzulängen. Der Abstand des hierzu notwendigen Paars von gehäusefesten Kontakten 9 von der mit der Durchtrittsöffnung 2 versehenen Stirnwand des Gehäuses 1 ist entsprechend gewählt. Danach wird der Eindrückhebel 21 umgelegt und die Kontaktierung vorgenommen. Der Eindrückhebel 21 ist gelangt dabei in Anlage an den Vorsprüngen 18. Der Eindrückhebel 21 hält die Zuleitungsdrähte 15 dann in der einmal eingenommenen Stellung, wobei insbesondere die Außenseite des Eindrückhebels 21 plan mit der offenen Längseite des Gehäuses 1 abschließt, da der Eindrückhebel 21 durch die Langlöcher 20 entsprechend eindrückbar ist.To mount the supply cable 3, the outer insulation of the Supply cable 3 stripped to a length that corresponds to the required maximum length corresponds to the exposed lead wires 15 thus exposed. Two isolated Lead wires 15 are with L-shaped bent ends in the slots 16 of the Support projections 11 and the respective insertion mouth of the slots 14 inserted. the two further insulated lead wires 14 are essentially U-shaped bent and also inserted. The U-shaped bending makes the excess length this lead wires 15 compensated and accommodated by housing 1 without that it is necessary to make these lead wires 15 shorter than the other two cut to length. The distance of the pair required for this from fixed to the housing Contacts 9 of the end wall provided with the passage opening 2 of the Housing 1 is chosen accordingly. Then the push lever 21 is flipped and made the contact. The push-in lever 21 has reached in Contact with the projections 18. The push-in lever 21 holds the lead wires 15 then in the position once taken, in particular the outside of the push-in lever 21 ends flush with the open long side of the housing 1, since the push-in lever 21 can be pushed in accordingly through the elongated holes 20.

Zum nachträglichen Prüfen des Schaltgeräts kann der Eindrückhebel 21 mit Schlitzen 31 zum Kontaktieren der gehäusefesten Kontakte 9 versehen sein.For subsequent testing of the switching device, the push-in lever 21 can also be used Slots 31 may be provided for contacting the contacts 9 fixed to the housing.
