Definitions

  • the invention relates to an insulation displacement connection element for electrical conductors according to the preamble of claim 1.
  • a further insulation displacement connection element is known from DE-GM 82 02 195, which has clamping legs bent along a transverse axis, which include a cranked middle bar. The inner cutting edges of the clamping legs also lie against the side edges of the central web to form an open clamping slot.
  • the invention is therefore based on the object to provide an insulation displacement connection element of the generic type, in which the contact connection between the connection element and the conductor core is improved, in which there is no risk of reducing the conductor core cross section and the risk of breakage of the conductor core, and in which also the conductor with a very thin conductor core diameter, especially also stranded wire, can be connected.
  • the cutting edges of the two clamping legs and the clamping web surrounded by them do not lie in one plane but in three mutually offset planes, the clamping slot having no air gap .
  • the cutting edges of the two clamping legs and the clamping web form a total of three interfaces in the three different levels with the conductor and its insulation and in particular with the conductor core, so that there is a good contact connection between the connection element and the conductor core, in which the conductor core cross section at the connection point is only slight is reduced in size so that there is no risk of the conductor core breaking.
  • the insulation displacement connection element in particular conductors with a very thin core diameter, including stranded conductors, can also be advantageously connected.
  • the two clamping legs are pivoted out of the clamping web and the conductor is centered by the oblique edges in the middle of the clamping slot, so that the conductor is pressed into the clamping slot between the clamping web and the two clamping legs.
  • the sharp edges of the two clamping legs cut through at two interfaces and the sharp edges of the clamping web at another interface isolate the conductor and contact the conductor core three times, so that an improved contact connection is achieved.
  • the two clamping legs overlap the clamping web by a certain range, so that the insulation displacement connecting element does not have an open clamping slot and, when the conductor is pressed in, all three edges lie against the conductor without an air gap.
  • the middle clamping web has a clamping leg on both side edges on its front and back, which is achieved by the formation of a metal bracket on the front and back of the clamping web.
  • two clamping slots are formed, each of which is delimited by the central clamping web and by two clamping legs.
  • the metal brackets arranged on the front and rear can be formed in one piece from a double metal bracket. This is made from a rectangular stamped part, which has two V-shaped cuts in the center, the tips of which are directed away from each other. The two metal brackets are bent 180 ° to one another centrally along the central transverse axis of the stamped part.
  • the insulation displacement connection element consists of a clamping web 4 molded onto a rectangular base body 18 and of a double metal bracket 1, which are each formed as stamped parts made of electrically conductive metallic material.
  • the clamping web 4 carries an upwardly projecting, central projection 19 which has sharp edges 24 on both sides.
  • One-piece metal brackets 7, 8, which form the one-piece double metal bracket 1 are arranged on the front and rear of the clamping web 4 and its base body 18. This is developed in its development as an essentially rectangular thin plate and has two mutually opposite V-shaped incisions 5, the vertices 6 of which are directed away from one another. Along the central transverse axis 23, the two metal brackets 7, 8 of the double metal bracket 1 are bent at 180 ° to one another in bending points 22. The two metal brackets 7, 8 lie on the front or Back of the clamping web 4 with a little lateral play. The clamping web 4 is thus guided between the two metal brackets 7, 8. The double metal bracket 1 and the base body 18 of the clamping web 4 are connected below one another in an electrically conductive manner below the apex 6 of the V-shaped incision via a spot weld connection 26.
  • the metal bracket 7 arranged on the front side has two clamping legs 2, 12 and the metal bracket 8 arranged on the rear side of the clamping web 4 has two clamping legs 3, 13.
  • the one to the sharp edges 24 of the clamping web 4 directed inner edges of the clamping legs 2, 3; 12, 13 are also designed as sharp edges 15.
  • oblique, sharp edges 25 are formed, which lie opposite the oblique, sharp edges 21 of the clamping web 4.
  • a conductor 14 To connect a conductor 14, it is first inserted into an insertion opening 17 formed above the oblique, sharp edges 21, 25. The conductor 14 is secured in this position by the cable lock 20 against slipping out. With a tool, not shown, the conductor 14 is now pressed into the clamping slot 9 formed between the sharp edges 15, 24. The directed oblique, scratched edges 21, 25 of the clamping web 4 or the clamping legs 2, 3; 12, 13 center the conductor 14 and cut the insulation 11 of the conductor 14 here in three places. The clamping legs 2, 3 and 12, 13 are swung out resiliently. The conductor 14 is now inserted into the clamping slot 9.
  • the conductor core 10 is tripled by the sharp edges 15 of the legs 2, 3; 12, 13 and the sharp edge 24 of the clamping web 4 contacted.
  • the clamping slot 9 delimited by the sharp edges 15, 24 is not tapered in parallel, but is tapered upwards in the direction of the cable securing device 20, so that the conductor 14 is fixed in the clamping slot 9 against slipping out. As a result, shaking movements cannot loosen the clamp connection. An additional position securing (bracket) for the contacting conductor is not necessary.
  • the outer edges of the clamping legs 2, 3; 12, 13 are provided in the region of the transition between the sharp inner edges 25, 15 with blunt V-shaped incisions 16, so as to enable a better distribution of forces from the conductor 14 to the connecting element.
  • connection element consists of the clamping web and two individual metal brackets, which, in contrast to the first embodiment, are not formed from a one-piece double metal bracket.
  • the connection of the two metal brackets to the web takes place at the lower end of the connection element via a spot weld connection and at the upper end via connection elements which can also be formed from spot weld connections with the interposition of spacers between the two metal brackets.
