Definitions

  • the invention relates to a contact element with double insulation displacement connection, according to the preamble of claim 1.
  • Contact elements are used for stripping-free electrical connection
  • Insulated electrical conductor often with insulation displacement connections provided, which consist of two parallel and with contact legs each provided with an insulation displacement contact slot and one of those contact legs together connecting middle section exist.
  • the insulation displacement connection forms usually a cross-sectionally U-shaped area.
  • Such a contact organ is for example known from EP-A-0 101 290.
  • the invention has for its object a contact element of the type mentioned with a compact, for contacting to create a suitable design for knife contacts.
  • a contact member according to claim 1ge In the case of such a contact element, this is the contact leg interconnecting middle part with at least one recess trained to insert a knife contact, so that in addition to its function as a connecting element for the contact legs at the same time as a plug contact area for a plug-in knife contact.
  • the contact element according to the invention can therefore be at height and overall length with very small installation dimensions and is particularly advantageously suitable for contacting of knife contacts perpendicular to the insulation displacement connection, d. H. of insertable perpendicular to the plane of the middle part Knife contacts.
  • the recesses in the middle section are with their opening width and appropriately designed in length and adapted to the geometry of knife contacts that the required Contact force is available.
  • the recess is slit-shaped, with approximately parallel to the free long sides of the middle section, so transverse to the contact legs. Such a recess can then directly the contact area for a form flat knife contact.
  • the middle part also serves in the contact element according to the invention as plug-in contact area for round or rectangular Contact pins and the slit-shaped
  • the recess is of a round or rectangular one Hole adapted to the geometry of a contact pin as the contact area interspersed for the contact pin.
  • the contact element 1, 1a and 1b is of a U-shaped cross section, from a sheet metal part in a stamping and bending process manufactured part with a double insulation displacement connection 2 for stripping-free electrical connection of an insulated electrical conductor 28 is formed.
  • the double insulation displacement connection 2 consists of two parallel to each other Contact legs 3, 4, each with an insulation displacement contact slot 5, 6 provided and here at their open Opposite insertion side of the insulation displacement contact slots Side over a bottom of the contact organ Middle part 7 are interconnected.
  • the insulation displacement contact slots 5, 6 are here z. B.
  • the middle part 7 of the contact element 1 is here with two to each other and parallel to the free long sides 13, 14 slot-shaped recesses 15, 16 formed, which are 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 over the bends of the contact legs 3, 4 stretch into them.
  • the central part 7 are the slot-shaped recesses 15, 16 each with a round, diametrically from the recesses penetrated breakthrough 17, 18 as a contact area for here knife contacts 19 designed as round contact pins, these breakthroughs then in the geometry of the Middle part 7 insertable knife contacts is adapted.
  • the Openings 17, 18 are on the plug side, that is, on the underside of the middle part 7, to facilitate the introduction the knife contacts with entries 20 in the form of an inlet radius or bevels.
  • the available size is the opening width of the Breakthroughs 17, 18 and the length of the slot-shaped recesses 15, 16 corresponding to the thickness of the knife contacts customized.
  • the contact legs 3, 4 on two opposite side edges 21, 22 have projections 23, which advantageously have a fir tree-like geometry, which in the illustrated Embodiment is reversed to that in Figure 1 from below acting on the central part 7 insertion forces to record.
  • the projections 23 are in the stable region of the Contact legs 3, 4 outside the insulation displacement contact slots 5, 6 and the openings 17, 18 are provided, to widen the insulation displacement contact slots 5, 6 or of the openings 17, 18 forming contact openings hinder.
  • the contact element in its middle part 7 with openings for pin-shaped knife contacts educated.
