Definitions

  • the invention be ensure.eine terminal for insulation displacement connection of electrical conductors in distributors of telecommunication installations, particularly telephone exchanges, comprising two ge in the longitudinal direction - severed and at its one end rigidly interconnected spring limbs which a clamping region for the electrical conductor and between the clamping area and the limit the rigid connection of the two spring legs extending elongated hole, the terminal is made in one piece from a metallic band material and the spring legs are separated in the clamping area by scissors.
  • Such a terminal is e.g. known from DE-AS 12 32 232. Because of its structure, a terminal of this type is easy to manufacture. It is disadvantageous, however, that a connection terminal constructed in this way does not meet the high requirements for contact reliability which are often required in practice.
  • the object of the present invention is to improve a connection terminal of the type mentioned in the introduction in such a way that, with simple production of the connection terminal, the high requirements for contact reliability are met at the same time.
  • the connecting terminal according to the invention also meets high requirements in terms of contact reliability with simple and inexpensive manufacture.
  • the spring legs cut into the wire and are thus fixed in this position.
  • the notches created during the cutting are offset by a small distance due to the entanglement of the two spring legs. If the wire is pushed further down into its final position, the spring legs twist, so that an additional torsional force occurs, which significantly affects the contact properties of the terminal according to the invention improved.
  • the single connecting terminal 1 shown in FIGS. 1 and 2 is a simple stamped part made of thin strip material with simple outer contours, which are formed by the straight outer edges of the spring legs and the terminal inlet 5.
  • the actual clamping area between the jaws 3 and 4 is limited by the clamp inlet 5 on the one hand and an elongated hole 2 on the other. This clamping area is produced using a simple separating cut.
  • the connection between the two clamping jaws 3 and 4 is torn through in the form of an entanglement which is decisive for the function of the connecting terminal according to the invention. Because of this entanglement, the stripping edges 6 and 7 of the clamping jaws 3 and 4 are separated from one another by the distance a at their ends facing the terminal inlet 5.
  • Fig. 3 shows a double terminal according to the present invention for connecting two insulated electrical conductors.
  • this double connecting terminal 8 is produced like the single connecting terminal described in FIGS. 1 and 2, but two separating cuts per terminal are required here.
  • a tongue 9 protrudes between the two clamping jaws 10 and 11 and is rigidly connected to one another at its unfree end by the unfree ends of the two jaws 10 and 11.
  • the double connection. clamp has two slots 12 and 13 and two clamp inlets 14 and 15, between which the respective clamping areas are located.
  • the two Stripping edges of a clamping area are each formed by an edge of one of the clamping jaws 10 and 11 and by an edge of the tongue 9.
  • the stripping edges of the two clamping regions are at a distance a from one another at their end facing the respective terminal inlet.
  • FIGS. 4 to 1Z. 4,6,8 and 10 each show a front view of the connection terminal 1 and in FIGS. 5,7,9 and 11 a top view of the connection terminal 1, or sections through the connection terminal 11 at the level of the electrical conductor while Fig. 17 shows a side view of the terminal after insertion of an electrical conductor.
  • the introduced electrical conductor 14 presses the terminal 1 slightly before the electrical conductor 14 with its insulation 15 reaches the stripping edges 6 and 7 (see FIG. 4).
  • the stripping edges cut into the wire 16 and fix the two clamping jaws 3 and 4 in this position. Since the clamping jaws 3 and 4 have been entangled with one another during the punching process - as explained above - the two notches caused by the stripping edges 6 and 7 in the wire 16 are offset by the distance a.
  • the stripping edges 6 and 7 are laterally deflected due to the rigid connection of the two clamping jaws 3 and 4 below the elongated hole 2 the level of the terminal 1, one of the stripping edges 6 and 7 deflected to the front, while the other of the two stripping edges 6 and 7 is deflected to the rear.
  • This gap causes a twisting of the two jaws 3 and 4, so that an additional torsional force p is exerted on the jaws 3 and 4.
  • additional grades are raised on the notches in the wire 16, which form an additional contact surface on the outside.
  • the contact surfaces which are formed by means of a separating cut, can be galvanically provided with contact materials, for example Ag or Sn.
  • the single connection terminals or double connection terminals according to the invention serve - extended at the base - as isolating or switching springs in distributor components.
