  • this assembly is still relatively uncomfortable and cumbersome.
  • DE 696 21 117 T2 discloses a connection arrangement in the form of a Housing with adjacent cutting contacts and one as Push lever for pushing wires into the cutting contacts
  • Known cover the cutting contacts adjacent to support projections and are arranged.
  • the wires are pressed into the cutting contacts the cutting contacts attached to the inside of the cover encompassing recesses having projections parallel to Pivot axis of the lid are spaced apart.
  • a connection arrangement is also known from DE 37 22 187 A1, at which is concentric according to the number of wires to be connected, by Isolation plates separate contact disks with staggered to each other Cutting contacts are provided in a housing that has a screw-on Has lid, which serves to hold the wires in the cutting contacts.
  • DE 199 50 244 A1 discloses a connecting terminal for electrical conductors Known for soldering onto a circuit board, which consists of a base and one swiveling upper part, which has two insulation displacement clamps between them form forming metal tape, which through an opening for soldering onto the PCB protrudes. After the wires have been inserted, contact is made through Squeeze top and bottom.
  • the object of the invention is to provide a switching device according to the preamble of To create claim 1, which allows convenient and safe contact.
  • Fig. 1 shows in perspective an embodiment of an open Switch device.
  • Fig. 2 shows a section along the central longitudinal plane of the switching device of Fig. 1.
  • FIG. 3 and 4 show in perspective the inside of an impression lever for a switching device of Fig. 1 from two different directions.
  • Fig. 5 shows schematically a switching device.
  • the switching device shown has a cuboid housing 1, which open on a broad side and can be closed there by means of a cover (not shown) is.
  • the housing 1 is at one end with a through opening 2 for a screw-in insert receiving a supply cable 3 (not shown).
  • a passage opening 5 for one in the housing 1 stored, biased by a spring 6 (see. Fig. 5) and in its Longitudinally displaceable plunger 7 is provided.
  • the straight ram 7 carries according to the switching functions of the switching device (NC, NO and Combinations of these) at least one, shown in Execution example two contact bridges 8, which by moving the Tappet 7 against its spring preload, each with two opposite contacts 9 fixed to the housing can be brought into or out of electrical contact, respectively after whether an opening or closing process should take place.
  • the switching device NC, NO and Combinations of these
  • the area of the plunger 7 is open from the rest to the broad side Inner area of the housing 1 as an intermediate floor 10 Control room cover separated, which is clipped on, for example.
  • the Intermediate floor 10 carries two pairs of in the longitudinal direction of the plunger 7 support projections spaced one behind the other 11.
  • the Support projections 11 support raised portions 12 of the space led out below the intermediate floor 10 on the other side housing-fixed contacts 9, which are with a central portion 13 on the Support intermediate floor 10 and are bent in an L-shape to the superscript Form sections 12.
  • the support projections 11 support the sections 12 according to the from the middle section 13 facing away.
  • 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.
  • 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.
  • 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.
  • 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.
  • a pair of spaced substantially L-shaped brackets 19 are adjacent to the front of the Housing 1, on which the passage opening 5 is located, so that an elongated hole 20 is formed between this housing wall and the brackets 19 becomes.
  • 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.
  • 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.
  • the push-in lever 21 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the push-in lever 21 can also be used Slots 31 may be provided for contacting the contacts 9 fixed to the housing.
