  • FIGS. 8 8a, 8b, 8c and 9 show two embodiments of cable couplings constructed in accordance with the invention.
  • a cable clamping ring 11 is mounted on the cable casing 10 and can be screwed in position if desired.
  • the end of the cable casing is crimped, on which again a conical pressure ring 12 fits.
  • the axial clamping action between the clamping ring 11 and the pressure ring 12 is obtained automatically on screwing home the plug connector head 13.

  • a seal 19 is placed between the clamping ring 11 and the screw threaded sleeve of the plug connector head. Sealing between the clamping ring 11 and the cable casing is carried out by means of a sealing mass 20, which can be injected through an opening which can be closed by means of a screw 21.
  • the cable is provided with solid or full insulation 22 between the internal conductor and the outer conductor and adjacent to the insulation there are insulating rings 23 and 24 of the cable plug connector, more particularly of foam material.
  • This internal conductor contact bush101 has its contact annular face lying against the front end face of an internal conductor pin 102 which is screwed into the cable internal conductor 103.
  • the internal conductor pin 102 carries a flange 104, which rests axially against the cable insulation 22.
  • This internal conductor pin 102 has a screw threaded hole, into which an internal conductor section 105 is screwed and the section 105 presses the inner flange 107 of the resilient bush against the internal conductor pin 102 by means of a flange 106.
  • the resilient tabs of the resilient bush .101 lie against the internal conductor section 105, which at its front end carries an insulating support 109 via a screwed in pin 108.
  • the support is carried in the external conductor plug connector section 110.
  • the pin 108 holds the internal conductor connection 111 of the insulating support 109. Owing to this internal conductor plug connector both radial and axial tolerances can be allowed for and in every case there is a satisfactory contacting via the resilient tabs.
  • the construction in accordance with FIG. 2 embodying the invention differs from that in accordance with FIG. 1 substantially as regards the construction of the plug connector head. While in the case of FIG. 1 the plug connector head has a nut with a lip acting as a shoulder, the plug connector head in accordance with FIG. 2 has an external screw thread, onto which a nut with a lip acting as a shoulder can be screwed. In accordance with FIG. 2 the external conductor bush 110 is divided up to form resilient tabs, while in the case of the embodiment in accordance with FIG. 1 it was rigid. As can be seen the plug connector in accordance with FIGS. 1 and 2 can be connected with each other.
  • the plug connector head is provided with an internal conductor bush, which resiliently engages the internal conductor of the cable.
  • an internal conductor plug connection of the type indicated in FIG. 1 is provided with a provision for allowing for eccentricity.
  • the internal conductor section 112 is screwed into the insulating support 109.
  • the step a of the internal conductor 112 at the exit of the support 109 is allowed for by a chamfered surface b of the sleeve with an internally extending lip.
  • an air gap is intentionally left between the foam material insulation ring 24 and the bush 101 which makes possible a compensation for eccentricity.
  • the dielectric formed as a result in layers is so arranged that it has the desired wave resistance.
  • the screw thread of the internal conductor section 112, with which it is screwed into the insulating support, is so dimensioned that with the dielectric constant of the insulating support 109 the desired wave resistance is ensured.
  • the external conductor plug connector connection is formed by a slotted bush 113 in the form of a deepdrawn hollow rivet.
  • the clamping ring 11 is provided with a nut 25 with an internal lip, which can be screwed onto an external screw thread 26 of the plug connector head.
  • a nut 25 with an internal lip, which can be screwed onto an external screw thread 26 of the plug connector head.
  • the clamping ring 11 can be so fixed that the end of the cable casing 10 can easily be crimped on.
  • the crimping tool in accordance with FIGS. 4 and 7 have inspection holes 114 (only indicated in FIG. 4), through which the position of crimping can be observed.
  • a helical compression spring 115 is provided which moves the sleeve 17 axially forwards in order to tension it so that on screwing on and screwing in the part 16 the crimping on is carried out evenly under a spring force.
  • the ring 240 of insulating material which surrounds the resilient bush 101 with clearance so as to leave an annular gap, is produced integrally with the insulating support 109a.
  • the attachment can be carried out by injection on (for example, using polytetrafluoroethylene) or by shrink ing on.
  • FIGS. 8 and 9 show cable couplings in the case of which instead of the plug connector head an intermediate piece 27 is provided, which is connected with the means secured in the cable.
  • the transition piece 27 is screwed into position, which has the same external screw thread 26 as the plug connector head.
  • the transition piece 27 is provided with an internal screw thread and is screwed onto a clamping sleeve 28, which clamps the clamping ring 11 in conjunction with the pressing ring 12 axially so as to pinch the crimped on end. Sealing is brought about in this case by means of a shrunk-on sleeve 29.
  • the inner conductor is again constructed as a plug connection in accordance with a double-ended construction with a resilient coupling sleeve 127, which as indicated in FIGS. 8a and 8b, respectively, is held by the insulating material rings 124 positively in an axial direction.
  • the bush 127 has an externally projecting collar 128, which fits into corresponding recesses in the insulating material rings.
  • the coupling spring connector 127 is axially held at the ends.
  • the bush is so clamped that the contact tab ends lie against the inserted inner conductor sections with a radially exerted resilient action.
  • the insulating material rings 124 are provided with a step 128a at the end, in order to accept an annular land 129 of the coupling sleeve 27 or a pressing ring 130, the latter lying in a machined out annular recess of the sleeve 27.
  • the rings 124 can be made of solid insulating mate rial or of foam material.
  • the dielectric is so constructed that the wave resistance tallies.
  • a laminated construction of insulating material and air is made and the air gap again allows for radial movement in order to compensate for eccentricity. In particular in the zone indicated by reference numeral 131 the construction is such that reflection is reduced to a minimum.
  • the pressing ring 12 can be provided with a corresponding axial extension.
  • the arrangement and construction of the inner conductor plug connection and the holding means for the insulating material rings 124 are to be selected ac- I cordingly.
  • the distance e is so chosen that the wave resistance is compensated for and no reflections occur.
  • the cable plug connector in accordance with the invention is generally applicable for cables with a metal casing, irrespectively of whether it is a question of a corrugated casing cable or a smooth casing cable. It can also be used in the case of cable casing welded in the longitudinal direction and in this case as well there is a satisfactory making of contact, because the crimping tool causes the weld seam to be polished and flat at the position at which crimping takes place.
