Definitions

  • the invention relates to an electrical coupling part for attachment to an electrical line, consisting of a mechanically stable carrier made of insulating material having at least two mutually parallel through holes for receiving electrical contact parts, which are connected in the mounting position to the stripped ends of electrical conductors each of which is surrounded by an insulation, in which in the mounting position around the line-side end of the carrier is formed around over the with a conductor enclosing jacket of insulating material equipped line extending, produced by injection molding protection body made of insulating material ( DE 36 23 927 C1 ).
  • Coupling in the context of the invention may be a plug with pins or a box with can contacts.
  • Contact parts are then either the connector pins or the can contacts.
  • the contact parts are inserted into through holes of prefabricated carriers made of insulating material.
  • the reasons of cost usually very simple, such as metal strips, shaped contact parts are equipped with a locking element, by which they are secured after insertion into a through hole of the carrier against axial displacement.
  • the contact parts do not fill the entire width of the through holes, but they sit relatively loosely in the same.
  • the spray material easily enters the through holes as well as the contact parts, which are then for contact are no longer usable. A corresponding coupling part would therefore either be reworked with great effort or thrown away as a committee.
  • a hot melt adhesive is applied before the spraying of the protective body on the surface of the carrier facing the line, which is readily flowable in the heated state and abruptly passes into a non-flowable state on contact with room temperature, cold parts.
  • the hot melt adhesive can thereby reach only up to the contact parts, but no longer penetrate into the through holes.
  • the through holes are firmly closed in this way by the solidified hot melt adhesive.
  • the material of the sprayed after applying the hot melt adhesive protection body can penetrate neither into the through holes of the carrier nor in the contact parts. This known method has proven itself in practice, especially in coupling parts with larger dimensions.
  • the initially mentioned DE 36 23 927 C1 describes a coupling member in which prior to fixing the conductor to the contact parts on the ends of all plastic conductors existing pipe pieces are pushed, whose inner diameter is at least partially slightly smaller than the outer diameter of the insulated conductors and whose outer diameter at least partially slightly larger than the inside diameter of the Through holes is.
  • the pipe pieces are moved at or after the insertion of the contact parts in the through holes on the conductors and inserted into the through holes.
  • the through holes of the carrier are sealed on the connection side, since they have a small excess compared to the through holes and thereby firmly abut against the wall of the same.
  • this sealing method no spray material can enter the through holes.
  • this known method has been proven in practice, especially in coupling parts for cables with a larger number of conductors.
  • the invention has for its object to make the above-described coupling part so that the sealing of the through holes and the contact parts used in the same is simplified, especially in coupling parts with smaller dimensions.
  • This coupling part is equipped with a carrier which has all the parts required for effective sealing of its through holes itself. Additional parts and / or materials are not needed.
  • the coupling part can thereby also have smaller dimensions.
  • the attached to the carrier and associated with the same, for example via film hinges latching flaps are firmly locked together in the mounting position. They enclose the insulated conductors so tightly that a hermetically sealed closure is achieved. There is thus a pressure and moisture-tight closure of the carrier. In injection molding of the protective body, therefore, its material can not enter the carrier, in particular its through-holes, and thus can not reach the contact parts located in the same.
  • a section through a coupling part K is schematically shown, which is attached to the end of an electrical line 1.
  • the line 1 has in the illustrated embodiment, two insulated electrical conductors 2 and 3, which are surrounded together by a jacket 4 of insulating material.
  • To the coupling part K includes a support 5 of mechanically stable insulating material, such as polyamide, which has two mutually parallel through holes 6 and 7.
  • electrical contact parts 8 and 9 are arranged, which are electrically conductively connected to the stripped conductors 2 and 3 at their ends.
  • the line 1 may also have more than two conductors.
  • the number of through holes in the carrier 5 depends on the number of conductors.
  • two latching flaps 10 and 11 are pivotally mounted as shown in FIG. 2, which shows a comparison with FIG. 1 offset by 90 ° section through the coupling part K.
  • they can be connected to the carrier 5 via film hinges 12 and 13.
  • the two locking flaps 10 and 11 are firmly locked together. They are in this position tightly and firmly on the insulation of the conductors 2 and 3 at.
  • a protective body 14 produced by injection molding of insulating material, such as polyamide, is formed, which extends over the jacket 4 of the line 1.
  • Fig. 3 shows a side view of the carrier 5 with attached latching flaps 10 and 11 in its open position.
  • One of the latching flaps may be equipped, for example, on two sides with a hook 15 (Fig. 4, left side), while the other latching flap then has on both sides laterally projecting pins 16 (Fig. 4, right side).
  • the two locking flaps 10 and 11 can each have a hook 15 on one side and a pin 16 on the other side.
  • the latching flaps 10 and 11 are shown in FIG. 4 at their intended to rest against the insulation of the conductors 2 and 3 ends with semicircular recesses 19 and 20, which in the mounting position with an entire length corresponding surface fixed to the insulation of the conductors 2 and 3 are pressed.
  • the coupling part K is produced, for example, as follows:
  • the two conductors 2 and 3 are exposed by removing the jacket 4 at the end of the line 1 to a predetermined length. Thereafter, the ends of the conductors 2 and 3 are stripped and the contact parts 8 and 9 are electrically conductively fixed thereto. The contact parts 8 and 9 are then inserted into the through holes 6 and 7 of the carrier 5. Then the two latching flaps 10 and 11 are brought to rest on the ladders 2 and 3 and locked together, with their hooks 15 engage over their pin 16.
  • the thus prepared line end with hermetically sealed carrier 5 is finally inserted into an injection mold, in which the protective body 14 is injected around the same. After cooling, the finished, attached to the end of the line 1 coupling part K can be removed from the injection mold.
