Definitions

  • the invention relates to a switching device according to the preamble of claim 1.
  • Such switching devices are used as position, safety switch or the like. used. It is also known to make the contacting of the switching device with a connecting cable via insulation displacement terminals, which are arranged in the housing of the switching device, see. EP 0 727 797 B1 , However, in this case the insulation displacement terminals are directed axially to the housing, ie against the passage opening for a supply cable. Despite simplification of the installation of the supply cable with respect to screw terminals, this assembly is still relatively uncomfortable and cumbersome.
  • connection arrangement in the form of a housing with juxtaposed cutting contacts and serving as a pressure lever for pressing wires into the cutting contacts lid is known, wherein the cutting contacts adjacent support projections and are arranged.
  • the impressions of the wires in the cutting contacts in this case done via mounted on the inside of the lid, the cutting contacts encompassing recesses having projections which are arranged parallel to the pivot axis of the lid spaced from each other.
  • Out DE 199 50 244 A1 is a connection terminal for electrical conductors for soldering on a board known, which consists of a lower and a pivotable upper part, which receive between them a two cutting clamps forming metal strip which projects through an opening for soldering on the board. After inserting the wires, the contact is made by squeezing the upper and lower part.
  • the object of the invention is to provide a switching device according to the preamble of claim 1, which allows a comfortable and secure contact.
  • 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).
  • 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.
  • the switching device NC, NO and combinations thereof
  • 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 mecanicklippst 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.
  • the raised portions 12 have a longitudinally extending slot 14 which ends at the top in a Ein Industriesmaul 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.
  • 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.
  • 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.
  • 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.
  • a pair of spaced substantially L-shaped brackets 19 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.
  • 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 harnessziehbar 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.
  • 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.
  • the indentation lever 21 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.
  • 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.
  • 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.
  • 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 Eind Weghebels 21, so that it does not bend by the contact ,
  • 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 ,
  • 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.
  • 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.
  • 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 Einmontmaul 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.
  • 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.
