Definitions

  • the invention relates to an electrical contact element of an electrical cable connector in insulation displacement technology with a flat fork spring for insulation displacement contacting an electrical cable and with a plug receptacle into which a plug of the electrical cable connector can be inserted.
  • Such an electrical contact element for the so-called insulation displacement technology is known from DE-PS 39 29 928.
  • the contact elements are punched out of sheet metal and bent in accordance with the specified shape.
  • An electrical contact element produced in this way is then arranged in a corresponding chamber of a plastic housing of the cable plug connection, after which the associated electrical cable is contacted on the electrical contact element using insulation displacement technology.
  • the electrical contact element has at least one fork spring, which defines an insertion slot between them, the mutually facing edges of the two fork spring legs being sharpened. In order to contact the electrical cable, it is inserted into the insertion slot of the fork spring, so that the cutting edges of the two fork spring legs scratch the cable insulation in such a way that they come into electrical contact with the electrical conductor. The two fork spring legs exert a clamping force on the electrical conductor so that it is held in the insertion slot.
  • Such a contact element according to the prior art also has a plug receptacle into which a plug of the electrical plug connection can be inserted.
  • Spring tongues arranged in pairs serve as the plug receptacle, between which, for example, the contact pin of a plug of the electrical plug connection can be inserted for contacting.
  • the disadvantage here is that such a cutting contact element is not able to transmit high currents of up to 16 amperes and that the contact resistance in the plug-in zone is greatly heated by the high contact resistance.
  • the invention has for its object to improve a contact element of the type mentioned in such a way that it is universally suitable for receiving conductor cross sections between 0.75 mm2 and 1.5 mm2 and high currents, such as up to to 16 amps for a conductor cross section of 1.5mm2 with less heating in the plug-in zone.
  • the connector receptacle is a flat receptacle.
  • a flat receptacle is proposed for the first time in combination in insulation displacement technology as a plug receptacle, which ensures a considerable reduction in contact resistance and makes the contact element in insulation displacement technology suitable for transmitting currents up to 16 amperes.
  • the connection of the connection with a flat plug can be plugged in easily, so that there is universal applicability, for example in the auto industry and white goods industry.
  • the security of the new connection technology is increased compared to the prior art.
  • the flat receptacle preferably has an accommodation space for the flat plug.
  • the accommodation space consists of a base plate with two side walls, the two free edges of which are angled inward above the base plate, the base plate having a locking clamp with a tumbler hook which snaps into a recess formed in the tab connector.
  • the fork spring and the flat receptacle have a common base plate have lateral material approaches of certain shapes, which are suitable for the creation of the accommodation space of the flat receptacle and the formation of the fork springs by successive bending processes.
  • the fork springs expediently have an opening which essentially forms the continuation of the insertion slot, leaving an intermediate web of the fork spring between the insertion slot and the opening, in order to increase the spring travel and thus the flexibility of the fork spring legs with a constant clamping force, so that overall the insulation displacement contact of the electrical cable is improved.
  • the contact element of the invention is intended to be used in the "RAST 5" program for domestic appliances, where it is particularly important to create a contact for conductor cross sections of 0.75 to 1.5 mm2, which can handle large currents up to 16 amperes can transmit in the plug-in zone without significant heating.
  • the contact element 1 shown consists of a flat stamped sheet metal part, from which the final shape is bent by successive bending operations, as can be seen in FIGS. 1, 2 and 3 of the drawing.
  • This electrical contact element 1 has on the front a plug receptacle 2 in the form of a flat receptacle 2, the base plate 3 of which is formed at the rear to form a fork spring 4 for the insulation displacement contacting of an electrical cable.
  • a plug receptacle 2 in the form of a flat receptacle 2
  • the base plate 3 of which is formed at the rear to form a fork spring 4 for the insulation displacement contacting of an electrical cable.
  • two fork springs spaced apart, each consisting of two fork spring legs 5, which define an insertion slot 6 between them for the electrical cable.
  • the fork springs 4 each have an elongated, slot-like opening 7, which extends as close as possible to the insertion slot 6, leaving an intermediate web 8. This opening 7 tapers towards the insertion slot 6, while the opening 7 also tapers towards the other end.
  • the base plate 3 of the fork spring 4 is extended at the front to form the flat receptacle 2 and is provided with lateral approaches in the plane, so that the flat receptacle 2 can be created by bending and punching in front of the fork spring 4.
  • the free edges 11, 12 are provided with a slight indentation, so that there is an arcuate course.
  • a tumbler hook 13 is worked out in the base plate 3 in the area of the flat receptacle 2, which interacts with a hole in the flat plug as a locking clamp.
