Definitions

  • This invention pertains to a ferrule and a method for using it to terminate a flexible microwave coaxial cable.
  • the invention provides termination for flexible coaxial cables, such as a microwave cable, by utilizing standard semi-rigid type connectors in combination with a metal ferrule which is soldered to the metal shields of the cable and optionally bonded to the insulation of the cable.
  • a ferrule for surrounding and supporting a flexible coaxial electric cable during hand or automatic termination to a connector comprising a concentrically fitting cylindrical electrically conducting metal tube, including sections have diameters to closely approximate the outer diameter of corresponding sections of coaxial cable prepared for termination.
  • a process for terminating a flexible coaxial electric cable comprising the steps of, (a) trimming to selected length at an end of said cable the layers of insulative and protective jacket, metallic shield, insulation between the shield and centre conductor, and said centre conductor to locate the ends of said layers at spaced apart intervals from one another, (b) inserting the trimmed cable end into an electrically conductive metal ferrule having portions of stepped diameter sized to approximately fit said jacket and metal shield respectively, (c) soldering or otherwise conductively securing said ferrule to said metallic shield, or alternatively bonding by adhesive means said insulative jacket to said ferrule, and (d) fitting a connector to said ferrule.
  • a flexible coaxial electric cable having an external jacket, a metallic shield and a centre conductor insulated from said shield, and prepared for fitting to a connector, the cable having at one end thereof a rigid metallic ferrule comprising tubular portions of stepped diameter, one portion fitting closely around the jacket of the cable and another section fitting around and contacting the exposed metallic shield.
  • the ferrule is formed from electrically conductive, readily shapable metal commonly used in electrical wire, cable and connectors, such as copper and its alloys, including brass formulations, plated aluminium, or plated steel or other ferrous metal compositions, and shaped to fit the connector chosen for use on the cable.
  • the end of the cable to be terminated is shaped to closely approximate the contour of the ferrule and overlap a portion of metal shielding and usually outer insulation or jacket, so that adequate bonding strength may be achieved by soldering the ferrule to the metal shielding and/or bonding if desired, such as by epoxy or other appropriate cement, glue, or adhesive, to the insulation or jacket.
  • FIG. 1 an end of a microwave coaxial cable is shown with an external jacket of insulation 1 removed from a layer of metal shielding 2, which surrounds an inner layer of insulation containing the centre signal contact 3. These parts of the cable have been trimmed to the proper length and the centre contact 3 pointed for termination with a selected connector of the known semi-rigid type.
  • the ferrule has a section 4 of larger diameter to fit over insulation 1, where it can be adhesively bonded, and a section 5 of smaller diameter sized to fit over the metal shield 2 portion of the coaxial cable and be soldered thereto by a standard method known in the art, for example through solder aperture 6.
  • a hand-termination tool well known in the art, now is used to grip the end of the ferrule after the cable and the connector parts are placed together and the end of the connector 9 between its jaws and the two parts urged together such that the end of the ferrule at termination rests against insulation block 7 and centre conductor 3 has penetrated and been firmly grasped by connector pin 8 as shown in Figure 1A, and tube wall 10 crimped to tube wall 5.
  • Figure 2 is similar to Figure 1, but centre conductor 3 is very small, smaller than standard semi-rigid, and its size requires increase for adequate termination in standard connectors. This is done by fitting the ferrule with a centre contact 12 of selected appropriate size affixed in the centre of a block of insulation 11 which is fitted into the small end of the ferrule. Termination of the cable can then proceed similarly as described above with Figures 1 and 1A to give a terminated cable as shown in Figure 2A.
  • Figure 3 illustrates a form of the invention in which the length of ferrule has been increased, terminated, and then formed at an angle so that an angled connector may be provided.
  • This invention thus provides a simple economical way to terminate a flexible cable by methods not normally lending themselves to such cables - a simple, cheap method for semi-rigid cable converted to use for a small, soft, flexible cable by a ferrule anchored to the cable end to be terminated.
  • the invention lends itself to automatic termination techniques as well as to individual assembly.
