Definitions

  • ABSTRACT The specification describes a coaxial plug connector, preferably for air-space insulated cable, and which is adapted to be sealed by means of self-curing synthetic resin injected into-annular sealing chambers.
  • the connector comprises a cable attachment part which is provided with annular grooves. These grooves form the annular sealing chambers and are connected with each other and with a filling opening by radial slots.
  • sealing of the plug connector with respect to the cable must be undertaken at two positions which are axially spaced.
  • sealing must be provided between the front part of the plug connector in order'to provide for a completely gas and-water tight connection between the line parts when the plug connection has been made, and on the other hand it is necessary to provide a seal between the plug connector and the outer casing of the cable in order. to prevent penetration of moisture between the outer cable conductor and the cable casing.
  • One aim of the present invention is to bring about this double sealing action by means of anelastic selfment part passes to the 'two axially spaced annular chambers and the front annular chamber brings about a formation of a seal between the front part of the plug connector and the'cable clamping means and the rear sealing chamber ensures the formation of a'seal between the cable tube, more particularly a'corrugated tube, and the cable grippingmeans.
  • the cable gripping means is in the form ofa nut adapted for use with corrugations. lnthis manner a reliable and permanent seal is provided for between the plug connector and the outer conductor of thecable, more particularly the corrugated tube outer conductor.
  • the composition injected into the rear sealing chamber also brings about the formation of a sealingmeans between the protective cable casing and the plug connector.
  • the cable attachment part is preferably constructed as a clamping ring, which can be slid onto the cable ing opening through the slots within the 'cable'attachan insulating support means.
  • This contact ring preferably has a radial hole for the passage of a gas filling, and the front part of the plug connector has a gas filling opening provided at this position.
  • FIG. 1 is an axial half section of a coaxial plug connector in accordance with the invention and fixedon a corrugated tube cable.
  • FIG. 2 shows a half section of the corrugated tube nut on a larger scale.
  • the coaxial plug connector consists of a plug connector head 1, on which a clamping nut 3 is screwed.
  • the rear part of the nut fits around the outer casing 5 of the cable.
  • a cable attachment part constructed in the form of a cable gripping part 2 is surrounded partly by the rear end of the plug connector head 1 and partly by the front end of the nut 3.
  • the cable gripping means is constructed as a corrugated tube nut and is screwed on the corrugated tube.
  • the front end of this corrugated tube is flared or broadened out to I form a contacting flange 10, which lies on the front end ring surface of the corrugated tube nut 2.
  • the corrugated tube nut 2 By axially clamping the parts 1 and 3 the corrugated tube nut,- supported axially in a positive manner by the nut 3, is clamped against the contacting flange 10 of the outer conductor against a contacting ring 9, which for its part is held or supported positively in an axial direction in the plug connector head.
  • the corrugated tube nut 2 has a rear annular gro0ve4, which forms the rear sealing chamberbetween the corrugated tube and the corrugated tube nut 2.
  • the filling opening is connectedvwith the I annular front-sealing space 6 and with the rear annular tube forming the outer conductor or can be screwed on in the case of a corrugated tube and can be clamped byv means of a screw connection between the front part of the plug connector and the rear part of the plug connector in an axial direction and clamps the crimped over end ring surface of the cable outer conductor or of the cable tube so as to make axial contact.
  • the clamping action is preferably carried out in this case by means of a contact ring, which is supported from the front on the crimped over end ring contacting face and preferably serves simultaneously for receiving sealing space 4 via connecting conduit or radial slots 8 in the corrugated tube nut 2. Via these slots 8 the synthetic resin composition injected in through the opening can pass into both annular sealing chambers so as to guarantee completely satisfactory sealing at both of the critical positions coming into question.
  • the sealing composition has been omitted in order to aid intelligibility.
  • the contact ring 9 surrounds an insulating support means 13, which to the. front rests axially against a step in the plug connector head, and to the rear rests against a step in the contacting ring 9.
  • This insulating support member 13 receives the inner conductor 14, which is made integrally and has a screw thread 15 by means of which it is screwed into. the internal conductor of the cable.
  • the plug nal key member 16 which through the plug Connector head 1.
  • the insulating supporting me mber 13 is injected'b etween the contact ring 9 and the internal conductor of the entire said plug connectorinto said attachment part periphery groove; 'said attachment part cablefacing side being provided 7 witha groove thatco'rnmunicates with said cable;
  • a plug connector according to claim '1 wherein both said periphery groove and said cable'facing side groove are annular, thereby-to enable sealing of said attachment part with sealing means.
  • sealing composition is injected through the. filling opening and this'com po'sition becomes distributed evenly amongst the annular sealing spaces and the slots.
  • the closing screw 7 of the-opening is screwed home again. Via the pressure connection sealed by the closing screw 11 the space between the inner conductor and the outer conductor can be filled with a suitable gasi Whatl'claimisr v 1.A plug connector for coaxial cables, comprising:
  • a cable comprising an internal conductor and an external conductor positioned around said internal conductorand spaced therefrom; said cable exterv nal conductor having a free endsection; a plugconnector-head which has an internal conductor therein and which'has anext'ernal conductor therein that is around its said internal and is spaced therefrom; said cable internal'conductor and said plug connector head internal conductor being electrically connected; said cable external conductor and said plug connector head external conductor being electrically connected; cable attachment part interposed between said cable and said plug connector head; said cable internal conductor passing through said attachment part; said cable external conductor also passing through said attachment part and its said free end section being supported against said attachment part near said plug connector head external conductor; 4 said'attachment part having a cable facing side which faces toward said cable and having an annular periphery; means connectedwith said cable and a portion of said plug connector head both passing around said attachment part periphery; said attachment part periphery being provided with a groove that com- .r
  • a sealing resin is deposited in said grooves and passes through 'said conduit between said grooves, thereby toseal-said cable to said plug connector.
  • a plug connector according to claim 2 wherein there are a plurality 'of said connecting conduits and 'they extend radially inwardly of said plug connector and between said grooves.
  • a plug'connector according to claim 4,'wher'ein said plug connector head inner conductor is fastened to said cable inner conductor by means of the former being screwed into the latter; said plug connector head inner conductor having a tightening means for tightening it against said cable inner conductor.
