Definitions

  • the invention relates to a cable connection element of the type specified in the preamble of claim 1.
  • Such fixed or pluggable cable connection elements with electrical devices serve to releasably connect the electrical connection points of such a device with the individual wires of an electrical cable in an electrically conductive manner.
  • Country-specific cable connection elements of this type are usually provided with screw terminals into which the individual wires of an electrical cable must be inserted and clamped one after the other (DE-AS 24 48 111). This is particularly tedious and time-consuming in the case of a control cable with a small wire cross section. For this reason, so-called spring-cage terminals have already been used instead of the screw terminals, but these are only very suitable for control cables with flexible stranded wires. It is also known to use so-called insulation displacement terminals instead of the screw terminals, into which the individual cable cores are pressed and clamped due to the elasticity of the core material. The work of clamping screws on each individual clamp is omitted. However, it is still necessary to insert every single wire under pressure into each assigned terminal. Since this push-in must take place evenly from both sides, this requires, especially again with cables with a small wire cross-section, special skill or a special tool.
  • the invention is based, from Exploitation of the basic advantages of an insulation displacement connection, particularly in connection elements with several electrodes, in such a way that the time required for establishing the cable connection can be reduced to a minimum without affecting operational safety.
  • the cylindrical cable connecting element shown in Fig. 1 is formed from a screw-like support body 1 with a rectangular thread 2 and a sleeve-shaped union nut 3 made of insulating material with a corresponding internal thread for screwing onto the support body 1 and with the sealing and strain relief rings 4 arranged between the two made of elastic material.
  • the union nut 3 has the shape of a sleeve open on one side and is dimensioned such that it completely covers the supporting body 1 in the cut state and axially projects beyond the insertion side by such an amount that a cavity for the accommodation of the rings 4 for cable strain relief and sealing is created .
  • the closed end face of the union nut 3 facing away from the support body 1 is provided with a bead 5 which closes the union nut 3 except for an opening 6 for the passage of the cable 7 (FIG. 2).
  • the support body 1 is fixedly connected to a device 8 at its end opposite the insertion side.
  • the support body 1 has from its insertion-side end face to the device-side end axially extending, symmetrically arranged, outwardly open groove-shaped recesses 9, 10, 11, 12 with a rectangular cross section for receiving insulation displacement clamps 13, 14, 15, 16.
  • These recesses are so designed that one of its walls in a diameter plane and the opposite, to the former parallel extending wall of the recess in question is arranged radially offset at a distance from the insulation displacement connector.
  • the insulation displacement connectors 13, 14, 15, 16, which are electrically connected to the respective device connection, are arranged, as shown in FIG. 3, in the recesses 9, 10, 11, 12 assigned to them in such a way that their broad sides, which extend transversely to the clamping notch, in the cross-sectional planes which are axially offset from one another in accordance with the thread pitch, approximately in the middle between the entry-side end face and the device-side end of the support body 1 with its apex surface, projecting into the thread comb.
  • the cable core located in the respective recess is first placed on the fanned-out outer edge of the cutting notch of the relevant insulation piercing terminal.
  • the strain relief for the cable 7 and for protection against the ingress of dust and moisture into the connecting element in the cable-side cavity of the union nut 4 is in the screwed state of the union nut 3 on the support body 1, as in fig. 2 shown, pressed by the bead 5 of the union nut 3 in the insertion area of the cable 7 against its surface and against the end face of the support body 1.
  • the union nut 3 rests dust and moisture-tight on an O-ring 21 made of elastic material and inserted into a groove of the supporting body 1 on the device.
  • the cable connection element according to the invention is a cable sleeve for connecting two cable ends or as a T-piece for connecting two cables to one device.
  • the corresponding cable connection element shown in FIG. 4 is also made of a screw-like support body 22 with the thread 23, which can be a normal metric thread, for example M14, and the sleeve-shaped union nut 3 with a corresponding internal thread for screwing onto the support body 22 and formed with a pressure body 24 arranged between the two made of elastic material.
  • the union nut 3 has the shape already described of a sleeve open on one side and is in turn dimensioned such that it completely covers the supporting body 22 in the screwed-on state and projects axially on the insertion side by an amount such that a cavity for accommodating the pressure body 24 instead of the rings4 (Fig. 1) arises.
  • the support body 22 is fixedly connected to the device 8 at its end opposite the insertion side.
  • the support body 22 has from its insertion-side end face to the device-side end axially extending, symmetrically arranged, outwardly open groove-shaped recesses 25, 26, 27 with an approximately rectangular cross-section for receiving the insulation displacement clamps 28, 29, 30. These recesses are coaxially symmetrical in the support body 22 let in.
  • the insulation displacement connectors 28, 29, 30 electrically connected to the respective device connection are, as shown in FIG.
  • the pressure body 24 is annular so that its outer diameter approximately corresponds to the inner diameter of the union nut 3 and its inner diameter approximately corresponds to the outer diameter of the cable 7 to be inserted.
  • the pressure body At its end facing away from the support body 22, the pressure body is feathered, so that after the union nut 3 has been screwed on, its inner wall, which tapers conically towards the cable entry side, can be compressed by such an amount that it presses the elastic ring 31 against the cable and relieves it of strain .
  • the pressure body 24 Towards the support body, the pressure body 24 is provided with fingers 32, 33, 34 which are elastic in the radial direction and are of such a length that they are in the abutting state of the pressure body 24 on the end face of the support body 1 above the insulation displacement terminals 28, 29, 30, the ends the fingers 32, 33, 34 are shaped so that they can be pressed in elastically by a certain amount.
  • the thread of the union nut 3 as shown in FIGS.
  • the union nut 3 rests on the device side on the elastic 0-ring 36 embedded in the support body 22 and on the insertion side on the elastic 0-ring 37 inserted in the pressure body 24, so that the interior of the connecting element prevents the ingress of dust and moisture is protected.
  • the special design of the pressure body 24 ensures that even very flexible cable cores are pressed perfectly into the clamping notches by its fingers 32, 33, 34, so that excellent electrical contacting can also be produced in this case.
