Definitions

  • the invention relates to a contact element with a double insulation displacement connection, which consists of two mutually parallel contact legs, each provided with an insulation displacement contact slot, and a central part connecting these contact legs to one another.
  • Contact elements for insulation-free electrical connection of insulated electrical conductors are often provided with insulation displacement connections, which consist of two mutually parallel contact legs, each provided with an insulation displacement contact slot, and a central part connecting these contact legs to one another.
  • the insulation displacement connection mostly forms a cross-sectionally U-shaped area, which is connected to a contact area of the contact element, for. B. is attached to a contact spring for contacting a plug contact or is formed in one piece with this contact area.
  • Such a contact member is known for example from DE-GM 89 09 562.
  • the invention has for its object to provide a contact member of the type mentioned with a compact, suitable for contacting knife contacts design.
  • a contact element of the type mentioned at the outset according to the invention in that the middle part is provided with at least one recess and this recess is adapted at least in a contact area for a knife contact which can be inserted into the middle part to the geometry of this knife contact.
  • the middle part connecting the contact legs is designed with at least one recess for inserting a knife contact, so that, in addition to its function as a connecting element for the contact legs, it also serves as a plug-in contact area for an insertable knife contact. In this way, a contact element can be realized in an extremely compact design with a double optical terminal connection and plug contact area.
  • the contact element according to the invention can therefore be manufactured with very small installation dimensions and length and is particularly advantageously suitable for contacting knife contacts which are perpendicular to the insulation displacement connection, ie knife contacts which can be inserted perpendicular to the plane of the central part.
  • knife contacts When knife contacts are inserted into recesses in the middle part, these recesses widen in the transverse direction, ie transverse to the free long sides of the middle part, and thereby generate the contact force.
  • the recesses of the middle part are expediently designed with their opening width and in their length and adapted to the geometry of the knife contacts in such a way that the required contact force is available.
  • the recess is advantageously slit-shaped, running approximately parallel to the free longitudinal sides of the central part, that is to say transversely to the contact legs. Such a recess can then directly form the contact area for a flat knife contact.
  • the middle part of a contact element according to the invention serves as a plug-in contact area for round or rectangular contact pins
  • the slot-shaped recess is penetrated by a round or rectangular opening adapted to the geometry of a contact pin as a contact area for the contact pin.
  • FIG. 1 shows a contact element with a double insulation displacement connection with a view of the underside.
  • FIG. 2 shows another contact element with a view of one side of the double insulation displacement connection.
  • FIG. 3 shows a further embodiment of a contact element and FIG. 4 the contact element according to FIG. 3 with a line and knife contact connection.
  • the contact element 1, la and lb is formed by a part with a U-shaped cross section, made from a sheet metal part in a stamping and bending process, with a double insulation displacement connection 2 for stripping-free electrical connection of an insulated electrical conductor 28.
  • the double insulation displacement connection 2 consists of two mutually parallel contact legs 3, 4, each provided with an insulation displacement contact slot 5, 6 and here on its side opposite the open insertion side of the insulation displacement contact slots via a central part 7 forming a base of the contact element are interconnected.
  • the insulation displacement contact slots 5, 6 are here, for. B.
  • the middle part 7 of the contact element 1 is formed here with two slot-shaped recesses 15, 16 which are parallel to one another and to the free longitudinal sides 13, 14 and which extend in the longitudinal direction of the middle part, that is to say transversely to the contact legs 3, 4, over the entire length of the Middle part and even extend into the bends of the contact legs 3, 4.
  • the slot-shaped recesses 15, 16 are each provided with a round opening 17, 18, diametrically penetrated by the recesses, as a contact area for knife contacts 19 designed here as round contact pins, these openings then corresponding to the geometry of FIG the middle part 7 plug-in knife contacts is adapted.
  • the openings 17, 18 are formed on the plug-in side, that is to say on the underside of the central part 7, in order to facilitate the introduction of the knife contacts with inlets 20 in the form of inlet radii or inlet bevels.
  • the contact legs 3, 4 have projections 23 on two opposite side edges 21, 22, which advantageously have a fir tree-like geometry, which in the case of the illustrated one Embodiment is reversed to absorb the insertion forces acting on the central part 7 from below in FIG.
  • the projections 23 are provided in the stable area of the contact legs 3, 4 outside the insulation displacement contact slots 5, 6 and the openings 17, 18, in order not to impede the opening of the insulation displacement contact slots 5, 6 or the openings 17, 18 forming contact openings.
  • a contact member in a housing, as in the contact member lb in Figures 3 and 4, for. B. on the rear side edges 26, 27 of the contact legs! 3, 4 to provide laterally bent mounting tabs 25, which in z. B. snap resilient locking elements inside the housing.
  • These fastening tabs are arranged in the contact element 1b directly below the insulation displacement area of the contact legs 3, 4.
  • the contact element 1b according to FIGS. 3 and 4 corresponds in its basic structure and the function and design of the central part 7 to the contact element 1 in FIG. 1, the contact element 1b only differing from the contact element 1 in that it differs from this only has a recess 15 for a knife contact designed as a round contact pin.
  • the contact member is formed in its central part 7 with openings for pin-shaped knife contacts.

Abstract
