Definitions

  • the present invention relates to an electrical socket, which either has the shape of a spring clip or the shape of a slotted sleeve with a spring element placed around the sleeve and exerting a radial pressure in the inserted state.
  • Electrical sockets in the form of a spring clip are e.g. B. from DT-PS 1 057 195 known. There is e.g. B. in Fig. 3 a socket with kidney-shaped cross section. Sockets, which consist of a slotted sleeve, around which a spring element which exerts radial pressure when plugged in, are known from US Pat. No. 3,316,528.
  • the requirement for electrical plug connections is that the contact resistance between the plug socket and the plug pin is as low as possible.
  • one of the two components usually the plug socket, is usually designed to be resilient.
  • the resilient design contributes to increasing the force required to plug or disconnect the connection, which is particularly disruptive when the forces required multiply accordingly in the case of multipole plugs.
  • the present invention is based on the object of specifying a plug socket for a plug-in device which, on the one hand, requires a relatively small amount of force when plugging and unplugging the connection, and on the other hand has a low contact resistance during operation.
  • the connector of the type described above differs from the previously known invention in that the spring clips or the spring element consist of a thermobimetallic material and are dimensioned and / or selected with regard to the material that the socket for receiving the for them at ambient temperature provided connector pin is sufficiently open, while at operating temperature it exerts a pressure on the connector pin that is stronger than the pressure achieved only by inserting the connector pin into the socket by elastic deflection of the socket.
  • the invention thus takes advantage of the fact that plug connections, especially those which carry relatively high currents, usually in the de-energized state, i. H. be opened or closed at ambient temperature, while they assume an increased operating temperature when current is passed. Under the influence of this temperature difference, the thermometallic material deforms and either exerts an increased pressure on the plug pin inserted into the socket, which reduces contact resistance or widens the opening for inserting or removing the plug pin.
  • Another advantage is that any wear and tear and the associated changes in resistance caused by the plugging process are at least partially compensated for.
  • a socket 1 is shown with a kidney-shaped cross section, into which a tongue-shaped connector pin 2 is inserted.
  • Fi g. 2 shows how the socket 1 consists of materials separated by a dotted boundary.
  • the spring clip is at ambient temperature shaped so that the connector pin 2 can be inserted or removed with little force.
  • the sleeve 1 is heated during current passage, it tends due to its thermobimetallischen material to like strength in F. 3 shown deform. This increases the pressure on connector pin 2 and reduces the contact resistance between connector socket 1 and connector pin 2.
  • the spring clip 3 has the shape of a polygon, here a triangular prism, which is open along one edge and engages around the indicated plug pin 4.
  • Such sockets are usually fixed on only one of the three sides, so that when the socket is produced according to the invention from thermobimetallic material, the other two sides lie around the plug pin 4 under the influence of temperature changes in the sense of a reduction or enlargement in cross section.
  • a socket 5 is shown in the form of a sleeve, which : is designed resiliently by slots 6 and receives the plug pin 7.
  • a spring element 9 is inserted, which has the shape of an open band-shaped ring 10 shown in FIG. 6.
  • this ring 10 consists of thermobimetallic material. Rings of this shape, however, tend to deform heart-shaped so that the two flanks 11 and 12 of the opening pull inwards. This can cause the pressure rise along the circumference of the groove 8 to become uneven.
  • the rings, as shown in FIG. 7, are chamfered at their ends 13 and 14 and lie next to one another in a ring shape.
  • Another possibility is to form the ring as an inclined or, as shown in FIG. 8, led in paragraphs.
  • the sleeve can also be formed from two curved tongues 15 and 10, which are resilient against one another, around which the ring 17 made of thermobimetallic material is placed.
  • thermobimetallic material is not only mechanically effective, but also fulfills electrically conductive functions, it is advantageous if this material consists of three or more layers, one of which is made of highly electrically conductive Material exists.
