Definitions

  • the invention relates to an insulation displacement connection element for contacting electrical conductors according to the preamble of claim 1.
  • a insulation displacement connection element of the generic type is previously described in the older DE patent 40 33 366 (prior art according to Article 54 (3) EPC).
  • the insulation displacement connection element is designed as a U-shaped profile piece.
  • the contact legs are cut free from the two side walls of the profile piece to form the insulation displacement contact and bent inwards between the side walls.
  • the two contact legs form a clamping slot into which a cable core is pressed. With multi-core cables, only one wire per connection element and not several wires can be contacted in parallel.
  • connection element in SMD technology. Only one wire can be connected to the circuit board at a time.
  • the invention is therefore based on the object of improving an insulation displacement connection element of the generic type in such a way that a plurality of parallel electrical conductors can be connected in a connection element and precisely positioned and guided.
  • the solution to this problem results from the characterizing features of claim 1.
  • the formation of the U-shaped profile piece with at least one central web enables, in addition to the safe guidance of the electrical conductor through the respective side wall and the base part and the at least one central web acting as a contact point, the parallel one Connection of several electrical conductors in one connection element. Due to its constructive design, the insulation displacement connector is well suited for use on printed circuit boards in connection with SMD technology (surface-mounted device technology). Another advantage is that the insulation displacement connection element does not require a housing to position the electrical conductors, it is self-supporting and does not require any reinforcing construction elements.
  • the first embodiment of the insulation displacement connection element 1 is shown.
  • This is designed as a U-shaped profile piece 2 made of an electrically conductive metallic material.
  • the profile piece 2 has two side walls 4, 5 which are bent at right angles from the base part 7.
  • two central webs 3 are cut out and, starting from the center, are bent upwards at right angles to the end faces of the profile piece 2.
  • the radii of curvature 13 result from the free cutting of the central webs 3 and their upward bending.
  • the central webs 3 form the connection points for the electrical conductors 6, an angle of 90 ° being formed between the central conductor axis and the contact points 9.
  • the notched bevels 8 formed at an angle of approximately 45 ° on the upper edge of the central web 3 cause any insulation on the electrical conductor 6 to be cut.
  • the distance between a side wall 4, 5 and the central web 3 is in each case somewhat less than the diameter of the to be connected electrical conductor 6, so that a firm clamp connection and good contact are guaranteed.
  • the length of the profile piece 2 is freely selectable.
  • the insulation displacement connection element 1 is designed for two electrical conductors 6, each of which is connected via two contact points 9 formed by the central webs 3.
  • an electrical conductor 6 for example in the form of cable wires of telecommunications and data technology
  • the electrical conductor 6 is inserted from above in parallel between a side wall 4, 5 and the central webs 3 in the profile piece 2 .
  • the electrical conductor 6 is held in each case by the inner surfaces of the side walls 4, 5 and the contact surfaces of the central webs 3.
  • the electrical conductor 6 is by means of a not shown Tool pressed into the contact slot of the insulation displacement contact 10, the sharp edges of the end faces of the central webs 3, which form the notched edges 8, cut through the insulation of the electrical conductor 6 and penetrate into the conductive core of the electrical conductor 6, whereby an electrical Connection between the electrical conductor 6 and the contact points 9 of the insulation displacement connection element 1 is made.
  • FIGS. 4 to 6 The second embodiment of the insulation displacement connection element 1 is shown in FIGS. 4 to 6. This differs from the first embodiment according to FIGS. 1 to 3 only in that the central webs 3 are bent up from the two end faces of the profile piece 2 towards the center (FIG. 5) or the one central web 3 from one end face to Is bent up in the middle (Fig. 6). This results in the radii of curvature 13. In the embodiment according to FIG. 6, only one contact point 9 is formed per electrical conductor 6.
  • the third and fourth embodiment according to FIGS. 7, 8 and 9 to 11 differ from the first and the second embodiment according to FIGS. 1 to 3 and 4 to 6 only in the number of middle webs 3 formed.
  • the embodiment chosen here With three central webs 3 it is possible to connect four electrical conductors 6, each with two or one contact point 9 (FIG. 11).
  • This embodiment shows that it is possible, depending on the selected width of the base part 7, to implement any number of connection points by lining up the basic shape of the insulation displacement contact element 1 in accordance with FIGS. 1 to 3 or 4 to 6.
  • contact points 9 In the fifth embodiment according to FIGS. 12 to 15 four contact points 9 (FIGS. 14, 15) or three contact points 9 (FIG. 13) are provided for each electrical conductor 6.
  • contact points 11 are formed from the side walls 4, 5 of the profile piece 2.
  • Contact strips 12 are cut free from the side walls 4, 5 and are bent into the interior of the profile piece 2 in a wide variety of shapes such that the contact points 11 acting in a clamping manner on the electrical conductor 6 are formed.
  • the angle between the longitudinal axis of the insulation displacement connection element 1 and the inwardly angled contact strips 12 can be freely selected.
  • the angle between the central axis of the respective electrical conductor 6 and the lateral contact strips 12 is preferably 45 ° to 90 °.
  • FIGS. 16 to 22 allow the connection of two electrical conductors 6 via four contact points 9, 11 (FIGS. 17, 18), three contact points 9, 11 (FIG. 22) or via two contact points 9, 11 ( Fig. 19, 20, 21).
  • the design of the center webs 3 corresponds to that in FIGS. 5, 6.
  • the design of the contact strips 12 corresponds to that in FIGS. 12 to 15.
  • FIGS. 23 to 25 and in FIGS. 26 to 29 show designs of the insulation displacement connection element 1 for four electrical conductors 6 in the design of the center webs 3 according to FIGS. 7 and 9 and in the design of the contact strips 12 according to FIGS. 13 to 15.
  • the individual embodiments of the central web 3 and the contact strips 12 can be combined with one another as desired and can be expanded for any number of electrical conductors 6 by lining up the basic shapes according to FIGS. 1, 4, 12, 16.
  • these embodiments can also be used for double contacting at a contact point if the diameter of the electrical conductors 6 is chosen to be almost identical.
  • the insulation displacement connection element 1 described is used as a wire connector for both bare and insulated conductors 6 in solid wire or stranded form or for connecting an equal number of conductors 6 to a printed circuit board, e.g. as an SMD contact.
  • the metal diameter of solid wires can be approx. 0.3 mm to approx. 1 mm depending on the size.
  • the connecting element 1 can also be used in connecting strips without a separating function.
  • the insulation displacement connector 1 is self-supporting. No additional construction parts, e.g. Housing, supports or the like, needed as reinforcement.
  • the electrical conductors 6 can either be cut to their correct length before wiring or can be severed by a metal edge during the pressing-in process. This edge can be bent out of the contact. A special wiring tool can also be used.
