Definitions

  • the invention relates to cable plug connectors for y fully insulated coaxial cables.
  • One aim of the present invention is therefore that of constructing a cable connector in such a manner that the spring contact ring does not need to be slid axially at all and is only placed radially on the external conductor.
  • the invention provides, in order to achieve this aim, that the spring contact ring is so gripped at its one edge portion in the sleeve surrounding the cable at its radial face that it is raised from the external conductor and the resilient contact ring is pressed by a sleeve, which is conically shaped internally, radially onto the external conductor.
  • the spring contact ring is clamped and soldered or brazed in the end side of ⁇ the screw threaded sleeve and the latter is screwed by means of a self-cutting internal screw thread on the protective casing of the cable.
  • the resilient contact ring which is preferably constructed in the manner of a comb, is spaced radially owing to its being clamped, from the external casing or external conductor so that the screw threaded sleeve can be screwed onto the protective casing without the contact ring coming into contact with the external conductor.
  • the radial pressing of the spring contact ring against the external conductor occurs on sliding on or screwing on the contact sleeve because the free edge portion of the spring contact ring runs onto the conical surface and thus passes with a certain amount of radial resilient deflection into contact with the external conductor. In this manner it is possible to ensure that even in the case of the presence of copper wire braiding or in the case of very thin foil conductors damage or displacement does not occur.
  • the spring or resilient ring and the contact sleeve it is also possible to ensure that the transfer of current occurs at the front end edge of the external conductor via the contact ring directly following the contact sleeve, while in the case of the previously proposed arrangement the making of electrical contact occurs via the spring contact ring in its middle section and the external conductor extends beyond this contact position to some degree.
  • the spring ring is preferably so arranged that its free edge portion extends axially somewhat beyond the end of the external conductor.
  • the contact sleeve is provided with a self-cutting inter nal screw thread and the front end of the cable dielectric, which has been bared by removing protective casing and external conductor has the contact sleeve screwed on it.
  • the screwing on of the contact ring onto the protective casing can be dispensed with.
  • FIG. l is an axial section of a coaxial plug connector mounted on a coaxial cable.
  • FIG. 2 is a view, corresponding to FIG. l, of a coaxial plug connector according to the invention with additional screw means for connecting the contact sleeve with the cable dielectric.
  • FIG. 3 is a' developed view of the spring contact ring.
  • FIG. 4 is a partial sectional view of the position at which electrical contact is made with the contact spring ring projecting beyond the external conductor.
  • the cable comprises an internal conductor 10, a cable dielectric l2, an external conductor 14, carried by the latter, in the form of aA thin copper layer, and an insulating material casting 16 for protective purposes.
  • the internal conductor 10 extends to the front beyond the cable dielectric.
  • the front part of the external con ductor is bared by removing the protective casing 16 and in this part the external conductor makes electrical contact with a spring contact ring 18.
  • the construction of the spring contact ring will become apparent on referring to FIG. 2. It comprises a cylindrical wound piece of resilient sheet metal with cutaway portions 20 extending from one side, and between these cut away portions 20 contact arms 22 are left.
  • the edge portion 24 of the spring contact ring 18 is inserted into a slit provided in the front side of the flange 32 of the screw sleeve 30 and isheld in this position by soldering or brazing.
  • the screw sleeve 30 is provided with a selfcutting internal screw thread and by means of this is screwed onto the protective casing 16. In the screwed on condition the flange 32, which is drawn inwards, lies against the end of the protective casing 16.
  • the spring contact ring 18 is so mounted in the flange 32 that, as shown inbroken lines in FIG. 2, it is spread and its contact making arms are raised from the external conductor. This ensures that there is no frettng of the contact making arms on screwing on onto the pro.- tective casing 16.
  • the arms 22 of the spring contact ring are pressed radially inwards on sliding on of a contact sleeve 28, because the front ends of the arms run along the internal conical surface 29 of this contact sleeve and are accordingly pressed inwards.
  • the two sleeves 28 and 30 are held together by means of a shoulder nut 34, whose rear flange 36 supports'the sleeve 30 axially and the nut is screwed on an external screw thread 38 of the sleeve 28.
  • a sealing ring 40 is laid, which ensures that the shoulder nut 34 is sealed.
  • the internal conductor 44 of the plug connector is carried via an insulating support 42 and theconductor 44 has a spring contact bush 46 at its rear end.
  • the spring lugs of this contact bush are provided with fingers 48 extending inwards, which make electrical contact radially with the internal conductor l0.
  • the embodiment of the invention in accordance with FIG. 2 differs from the plug connector in accordance with FIG. 1 in that the cable dielectric l2 in a front section 13 extends over the external conductor 14, that is to say in this front section the cable dielectric is bared because there is no external conductor.
  • the correspondingly extended contact sleeve 28a is provided in this respect with a self-cutting internal screw thread, 31, which is screwed on the front part 13 of the cable dielectric.
  • the cable plug connector in accordance with FIG. 2 corresponds to that described with reference to FIG. 1.
  • the contact arms lie like the arches of a bridge within the free space 26 enclosed by the contact sleeve and make electrical contact with the external conductor 14 approximately in the middle.
  • the arms 22 of the spring contact ring extend into the section 23 beyond the end of the external conductor 14 and are accepted by an annular groove 29a, which adjoins the conical surface 29 and the end of the resilient arms are pressed thereby against the cable dielectric I3. This ensures that the front edge l5 of the external conductor is contacted electrically by the spring arms 22 so that the current can flow in one direction from the external conductor via the contact making arms to the contact sleeve.
  • a cable plug connector for insulated coaxial cable 1.
  • the cable comprises an internal conductor, a dielectric layerl outside said internal conductor, a thin metal layer external conductor'positioned around and supported on said dielectric layer and an external protective casing of insulating material around said external conductor; an annular section of said casing is removed to facilitate electric contact with said external conductor;
  • said connector comprises a first sleeve positioned around said external protective casing of said cable; said first sleeve having a first end;
  • a resilient spring contact ring around said exposed annular section of said external conductor; said ring having one edge portion which is supported said first sleeve at its said first end; said ring having a free edge portion opposite its said one edge portion; said ring is so shaped and oriented in said first sleeve that its said free edge portion is normally raised above said annular section of said external conductor and is radially deflectable inwardly against said annular section of said external conductor;
  • a second sleeve with a first end that faces toward said first sleeve first end and having a bore near said second sleeve first end; said second sleeve bore is shaped to cause said ring free edge portion to deflect radially inwardly and to cause said ring to engage said external conductor annular section, and is shaped to cause such deflection of said ring as said second sleeve first end is moved toward said first sleeve first end.
  • each said lug is curved radially outwardly to form an arch and is so shaped and oriented that said lugs are forced inwardly by said second sleeve bore to cause their center portions to engage said external conductor.
