Definitions

  • An electrical connector for coaxial cable includes an inner ferrule and an outer tubular contact spaced from but in axial alignment with the ferrule.
  • the ferrule and tubular contact are integrally connected by a member which is severable on crimped connection of the ferrule to the inner conductor of a coaxial cable.
  • the tubular contact contains a spacer of electrically insulating material having an axially extending through hole.
  • a method of connecting an electrical connector as defined aboveto the end of a coaxial cable comprises the steps of removing a portion of outer insulation sleeve from the end of the cable to expose a length of outer conductor, removing aportion of dielectric material from the end of the cable to expose a length of inner conductor, threading the tubular member over and rearwardly of the preparedend of cable, passing the inner conductor through the axially extending hole in the spacer until an end portion is received in the ferrule, positioning.
  • the ,outer; conductor so that an end portion surrounds the tubular contact, crimping the inner ferrule to the inner conductor, severing the member, passing the tubular member over.the tubular' contact so that the outer conductor is sandwiched between the tubular member andthe tubular contact and crimping the tubular member to the tubular contact.
  • two tubular contacts are provided one at each of two opposed ends of a connecting member, the outer tubular contacts being positioned in axial alignment, and two ferrules,-the ferrules being arranged in axial alingment with and between. the tubular contacts and supported by a branchfmember integral with the connecting member, the branch memberbeing severable when the innerferrules are; crimp; connected to inner conductors of respective coaxial-cables.
  • FIG. 1 is a view, partly in cross-section of an electrical connector connecting the opposed ends of two coaxial cables;
  • FIG. 2 is a cross-section on the line II-II of FIG. 1;
  • FIG. 3 is a side view of part of the electrical connector of FIG. 1;
  • FIG. 4 is a cross-section on the line IV-IV of FIG.
  • FIG. 5 is a view similar to FIG. 3 but illustrating an assembly operation of the electrical connector; and FIG. 6 is a plan view of part of the electrical connector of FIG. 1.
  • a coaxial cable 1 comprises an inner conductor 3, dielectric material 5 separating the inner conductor 3 from an outer conductor 7 and an outer insulation sleeve 9.
  • the inner conductor '3 is' a copper wire
  • the dielectric material 5' is expanded polyethylene
  • the outer conductor 7 comprises an inner tube 6 of copper and an outer tube 8 of steel
  • the outer insulation sleeve 9 is a treated paper.
  • an electrical connector'for electrically connecting the opposed ends of two coaxial cables includes two' ou'ter'tubular contacts 10 and two inner ferrule's l2 blanked and formed from a single strip of electrically conductive sheet material, for example," brass.
  • the tubular contacts 10 are in axial alignment and are positioned one at each end of an elongate connecting member 13.
  • An outer portion 14 of each tubular contact is tapered to define a conical inne r surface 16.
  • a branch 'member 18 extends from the, connecting member 13and supports thetwo inner ferrules 12.
  • the inner ferrules are in axial alignment with the tubular contacts 10.
  • Each inner ferrule 12 has a pair of side walls 20 interconnected by a bight portion 22 to define a generally U-configura tion.
  • A After blanking and forming, a plurality of tubular contacts 10 and associated inner ferrules 12 are maintained in strip form by carrier strips 24.Whilst still in strip form successive pairs' of tubular contacts are bent as indicated in FIG. 5 to permit assembly of a spacer 26 in each tubular contact 10 of the pair. Subsequent to the assembly of a spacer 26 in a tubular contact 10 a lip 28 is formed around the periphery of the tubular contact to prevent withdrawal of the spacer 26. Each spacer 26 has an axially extending through hole 30 and a conical surface 32 which engages the surface 16 to locate the spacer 26 in the tubular contactlO. After assemblyof the spacers 26, each tubular contact 10 of a pair. ,is bent back intoaxial alignment as shown in FIG.
  • the electrical connector further includes a tubular member 34 of copper, a tubular shield 35 of magnetic material,.for example, mild steel and an outer tubular shield 36 of thermosetting, heat-shrinkable plastics material;
  • the tubular shield 35 is inserted within the outer tubular shield 36 and forms with it a tubular shield subassembly.
  • the tubular shield 35 has longitudinal edges which overlap to allow for any decreas'e in diameter of the-outer. tubular shield 36 when heatis applied to shield36. 7
  • tubular member 34 and the tubular shield sub-assembly comprising the tubular shield 35 and outer tubular shield 36 are threaded over and rearwardly of the prepared end of one coaxial cable 1.
  • Each inner conductor 3 is then passed through a hole 30 in the spacer 26 of a tubular contact 10 until an end portion is received in the inner ferrule 12 adjacent the tubular contact 10.
  • the exposed length of each outer conductor 7 is flared so that it surrounds its respective tubular contact 10.
  • the inner ferrules 12 are then crimped to their respective inner conductors 3 and simultaneously the branch member 18 is severed.
  • the tubular member 34 is passed over both tubular contacts thereby sandwiching each outer conductor 7 between the tubular member 34 and its respective tubular contact 10.
  • tubular member 34 is then crimped to each tubular contact.
  • tubular shield sub-assembly is passed over the tubular mem: ber 34 and by the application of heat, the outer tubular shield 36 is bonded at each end to the outer insulation sleeve 9.
  • a single inner ferrule 12 and complementary tubular member can be used to terminate a single coaxial cable 1.
  • An element for use in an electrical connector for connecting the opposed ends of two coaxial cables comprising a pair of ferrules arranged in axial alignment and being connected to each other, said ferrules being for crimped connection to the inner conductors of the coaxial cables, a pair of tubular contacts disposed one at each of two opposed ends of a connecting member, the tubular contacts being positioned in axial alignment with each other and with the pair of ferrules, the ferrules being disposed between the tubular contacts and supported by a branch member integral with the connecting member, the branch member being severable when the ferrules are crimp connected to the inner conductors of the coaxial cables, and a spacer of electrically insulating material disposed in each said tubular contact and having an axially extending through hole in alignment with the ferrules.
  • a method of electrically connecting the opposed ends of two coaxial cables with an electrical connector wherein the electrical connector comprises two tubular contacts, one at each of two opposed ends of a connecting member and in axial alignment, two ferrules arranged in axial alignment with and between the tubular contacts and supported by a branch member integral with the connecting member, and two spacers of electrically insulating material contained by said tubular contacts, each said spacer having an axially extending through hole, and a tubular member, the method comprising the steps of removing a portion of outer insulation sleeve from the end of each cable to expose a length of inner conductor, threading a tubular member over and rearwardly of the prepared end of one of the cables, passing each exposed inner conductor through the axially extending hole in the spacer of the tubular contact until an end portion is received in the ferrule adjacent the tubular contact, positioning each outer conductor with an end portion thereof surrounding a respective tubular contact, crimping the ferrules to their respective inner conductors, sever
