Das dargestellte Schaltgerät besitzt ein quaderförmiges Gehäuse 1, das an einer Breitseite offen und dort mittels eines Deckels (nicht dargestellt) verschließbar ist. Das Gehäuse 1 ist an einer Stirnseite mit einer Durchführungsöffnung 2 für einen ein Zuleitungskabel 3 aufnehmenden, einschraubbaren Einsatz (nicht dargestellt) versehen. An der der Durchführungsöffnung 2 gegenüberliegenden Stirnseite des Gehäuses 1 ist eine Durchtrittsöffnung 5 für einen im Gehäuse 1 gelagerten, mittels einer Feder 6 (vgl. Fig. 5) vorgespannten und in seiner Längsrichtung verschiebbaren Stößel 7 vorgesehen. Der geradegeführte Stößel 7 trägt entsprechend den Schaltfunktionen des Schaltgeräts (Öffner, Schließer und Kombinationen hiervon) wenigstens eine, im dargestellten Ausführungsführungsbeispiel zwei Kontaktbrücken 8, die durch Verschieben des Stößels 7 gegen seine Federvorspannung jeweils mit zwei gegenüberliegenden gehäusefesten Kontakten 9 in bzw. außer elektrischen Kontakt bringbar sind, je nachdem ob ein Öffnungs- oder Schließvorgang erfolgen soll.The switching device shown has a cuboid housing 1, which is open on a broad side and there by means of a lid (not shown) can be closed. The housing 1 is provided at one end face with a passage opening 2 for a feed cable 3 receiving, screw-threaded insert (not shown). At the passage opening 2 opposite end face of the housing 1 is a passage opening 5 for a mounted in the housing 1, by means of a spring 6 (see. Fig. 5 ) and preloaded in its longitudinal direction displaceable plunger 7 is provided. The straight guided ram 7 carries according to the switching functions of the switching device (NC, NO and combinations thereof) at least one, in the illustrated embodiment, two contact bridges 8, by moving the plunger 7 against its spring bias each with two opposite fixed contacts 9 in or out of electrical contact can be brought, depending on whether an opening or closing operation should take place.

Der Bereich des Stößels 7 ist vom übrigen, zur Breitseite hin offenen Innenbereich des Gehäuses 1 über einen Zwischenboden 10 als Schaltraumabdeckung getrennt, der beispielsweise aufgeklippst ist. Der Zwischenboden 10 trägt zwei Paare von in Längsrichtung des Stößels 7 hintereinander beabstandet angeordneten Stützvorsprüngen 11. Die Stützvorsprünge 11 stützen hochgestellte Abschnitte 12 der aus dem Raum unterhalb des Zwischenbodens 10 auf deren andere Seite herausgeführten gehäusefesten Kontakte 9, die sich mit einem Mittelabschnitt 13 auf dem Zwischenboden 10 abstützen und L-förmig umgebogen sind, um die hochgestellten Abschnitte 12 zu bilden. Die Stützvorsprünge 11 stützen die Abschnitte 12 nach der vom Mittelabschnitt 13 abgekehrten Seite hin ab.The area of the tappet 7 is separated from the rest, open to the broadside inside region of the housing 1 via an intermediate bottom 10 as a control room cover, which is aufgeklippst example. The intermediate floor 10 carries two pairs of spaced longitudinally of the plunger 7 arranged support projections 11. The support projections 11 support superscript sections 12 of led out of the space below the intermediate floor 10 on the other side housing fixed contacts 9, which extends with a central portion 13 on the Support intermediate bottom 10 and are bent in an L-shape to form the raised portions 12. The support projections 11 support the sections 12 from the side facing away from the central portion 13 from side.

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 portions 12 have a longitudinally extending slot 14 which ends at the top in a Einführmaul for an insertable transversely to the longitudinal direction of the plunger 7, insulated lead wire 15 ends. Of the raised portion 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 14 parallel to the slots 16 with a width slightly larger than the diameter of an insulated lead wire 15, while the width of the slots 14 is slightly smaller than the diameter of the lead wire itself, so that the legs 14 forming the leg as cutting serve, which sever the insulation of the lead wire 15 and contact the lead wire itself by clamping electrically.

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 inlet side to the slot 16 with these narrowing projections 18, so that an undercut is formed and an inserted insulated lead wire 15 thereof is held in this position and does not spring back or fall 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 and arranged in a generally cruciform manner to form substantially rectangular receiving areas or recesses for the middle sections 13 of the contacts 9 with corresponding housing walls or projections.

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.At the intermediate bottom 10 are adjacent to the end face of the housing 1, at which the passage opening 5 is located, a pair of spaced substantially L-shaped brackets 19, the free legs are directed to the adjacent housing wall and adjacent to this, so that between this Housing and the straps 19 a slot 20 is formed.

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.In the long holes 20, a push-in lever 21 is hooked by means of projections 22 on a fork-shaped extension 23 snapping, so that the fork-shaped extension 23 forms a hinge for the push-in lever 21 with the brackets 19. Because of the elongated holes 20 of the indenting lever 21 in the joint is hochziehbar so that it can be placed with a front side 24 on the housing 1 and thereby held in its open position. This will cause the assembly of the Lead wires 14 facilitates.

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 indenting lever 21 is formed as an intermediate cover closing the housing 1 on its broad side and has a substantially 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 indentation lever 21 has webs 26 which, when closing the push-in lever 21, press the insulated feed wires 15 located above the slots 14 into the slots 14 for the purpose of making electrical contact. Accordingly, the lands 26 have a width substantially corresponding to 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.Conveniently, the webs 26 are T-shaped, with the transverse legs formed thereby serving to support the insulated lead wires 15 on the side of the support projections 11 from which the lead wires 15 are inserted into their slots 16.

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.Characterized in that the cutting contacts are arranged in pairs in the longitudinal direction of the plunger 7 in the housing 1 and the indenting lever 21 is pivotally hinged to the housing 1, the contacting takes place in pairs one after the other, so that the contact without additional aids on a depression of the indenting lever 21 are made safe can.

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.Further, the indentation lever 21 of the illustrated embodiment has adjacent to the T-shaped webs 26 at least one retaining tongue 27 which supports the superscript portion 12 and central portion 13 of the respective contact 9 when pressing the Eindrückhebels 21, so that it does not bend by the contact , In this case, in the illustrated embodiment adjacent to the joint of the push-in lever 21 two spaced apart in the longitudinal direction of the plunger 7 holding tongues 27 are provided, while for the further pair of contacts 9 each have a retaining tongues 27 and a projection 28 for holding down the central portions 13 of the contacts 9 are provided ,

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

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 with a located on the side remote from the hinged end of the indenting lever 21 end wall 30 a chamber for receiving one end of a corresponding lead wire 15, so this, when a metallic shielded cable 3 is used, not with the metallic shield in contact can get.

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.For mounting the feeder cable 3, the outer insulation of the feeder cable 3 is stripped to a length corresponding to the required maximum length of the insulated feeder wires 15 thus exposed. Two insulated lead wires 15 are inserted with L-shaped bent ends in the slots 16 of the support projections 11 and the respective Einführmaul the slots 14. the other two insulated lead wires 14 are bent substantially U-shaped and inserted as well. Due to the U-shaped bending the excess length of these lead wires 15 is compensated and received by the housing 1, without it being necessary to cut these lead wires 15 shorter than the other two. The distance of the necessary pair of housing-fixed contacts 9 of the provided with the passage opening 2 end wall of the housing 1 is selected accordingly. Thereafter, the indenting lever 21 is folded over and made the contact. The indenting lever 21 holds the lead wires 15 then in the once occupied position, in particular the outside of the indenting lever 21 is flush with the open longitudinal side of the housing 1, since the indenting lever 21 through the Long holes 20 is pressed accordingly.

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 of the indenting lever 21 may be provided with slots 31 for contacting the housing-fixed contacts 9.
