Definitions

  • the invention relates to a clamping device for mechanical holding and for contacting the inner conductor of a coaxial cable according to the preamble of claim 1, the component e.g. an antenna socket.
  • Clamping devices of this type are required in a wide variety of connection elements for HF transmission, in particular in antenna sockets and for HF device connections.
  • High demands are placed on the galvanic contact and on the holder of the inner conductor of the coaxial cable, so that the safe and permanently conductive connection necessary for the transmission of high and very high frequencies is ensured between the inner conductor and the further connection contact.
  • a clamping device with the features reproduced in the preamble of claim 1 is described in DE-P 35 30 721. It has a lower part made of insulating material, on the surface of which a wire end running transverse to the longitudinal axis of the inner conductor is held. It establishes the connection to the circuit board in an antenna socket.
  • the upper part of the terminal arrangement consists of a clamp that can be screwed against the lower part with a pressure piece made of insulating material that presses on the inner conductor.
  • the connecting wire lies firmly on the lower part of the terminal.
  • the upper part of the clamp and the pressure piece are also rigidly guided on the associated screw.
  • FR-A 21 91 296 (corresponds to DE-P 22 23 112) describes L-shaped angled connecting wire elements, the short leg of which is arranged axially parallel to the inner conductor of a coaxial cable in a receptacle in the lower part of the terminal. The leg is enclosed on three sides by the insulating material of the socket body, and only its surface facing the inner conductor is free for support and contacting.
  • a clamp connection has become known from a related field - the electrical connections - in which the lead wire is clamped by spring force.
  • the wire is pressed by the return force of a curved spring band against one side of a metallic plate, on the other side of which there is a further connecting wire.
  • the intermediate part is necessary because the connecting wire in the terminal is axially parallel is arranged to the lead wire to be clamped (as in the known screw luster terminal the wires to be connected). Without the intermediate part, it would not be possible to clamp conductor wires with a diameter unequal to that of the connecting or connecting wire with this principle.
  • the clamp construction is quite complicated and therefore expensive, but still not reliable.
  • the invention has for its object to improve a screw-clamping device of the type specified in the preamble of claim 1 in such a way that the functional reliability of the connection, ie the quality and durability mechanically and galvanically, sustainably improved, and thus particularly for the transmission of high and very high frequencies required security of the electrical connections, regardless of the wire diameter and the material properties, is increased
  • This object is achieved with the features specified in the characterizing part of the main claim.
  • Favorable design variants and details are shown in the subclaims.
  • the inner conductor wire is bent when the screw 6 is tightened between the gable roof-shaped lower part 3 and the complementary pressure piece 5 and thus additionally secured against axial tension. He presses the contact arm 9 of the connecting element against its spring resistance into the groove 8 in the apex area of the lower part surface 7. As long as there is clamping, the contact arm tends to stand up and in turn presses against the inner conductor wire. This is - depending on the dimensional relationships between the contact arm, the lower part surface and the groove base and of course the material of the connecting element - a sufficient reserve of clamping force in the event that the screw clamp loosens for the various reasons described above .
  • Figure 2 shows an example of the structural design of the connecting element for - in this case - circuit board inside the socket.
  • the roof shape of the lower part 3 continues and forms a cutting edge which is favorable for contacting.
  • the flattening 11 can be seen, with the lateral protrusions of which the element is held and supported in the complementarily designed receptacle 12 of the bushing in the lower part 3.
