Definitions

  • a joint between coaxial cable ends includes an outer tubular shell in two symmetrical halves having a wider diameter midsection and narrower diameter ends. Outer sleeves are placed around each shell end over the outer coaxial conductors and reinforcing sleeves are disposed over dielectric spacers within the outer conductors. An inner sleeve is crimped over the two inner conductor ends and a section of dielectric spacer is positioned around the inner sleeve.
  • outer tubular shell portions are placed around the inner sleeve and spacer with the narrow portions over the reinforcing sleeves and outer conductors.
  • the outer sleeves are crimped over the narrow shell ends to lock them in place. Characteristic impedance across the joint is maintained by a proper sizing ratio between the outer diameter of the inner sleeve and inner diameter of the midsection of the shell.
  • This invention relates to jointing arrangements for coaxial cores or cables and particularly to an improved joint having diameter ratios of the components selected to maintain a characteristic impedance.
  • the sleeve must be slightly bigger in outside diameter than is the diameter of the inner conductors.
  • the outer conductors of the bore has, up to now, been joined by a simple tube having an inner diameter substantially the same as the outer diameter of the outer conductors.
  • a plurality of shells are positioned to form a tubular enclosure about the joined inner conductors and inner sleeve.
  • the enclosure has a midsection of larger diameter than its ends, with the narrower ends encircling the ends of the coaxial cores to be joined at points where reinforcing sleeves lie under the outer conductors.
  • the tubular ends are in turn encircled by outer sleeves which are crimped to lock the enclosure in position relative to the cores, and the ratio of the inner diameter of the enlarged shell enclosure, where it surrounds the inner conductors and sleeve, to the outer diameter of the inner sleeve, is so chosen as to maintain the characteristic impedance of the cores.
  • FIG. I is an exploded view of a joint arrangement, not accurately to scale so that details may be clearer;
  • FIGS. 20, b, and c are plan, side and end views of an outer conductor jointing shell shown in FIG. 1;
  • FIG. 3 is a section, with scale greatly distorted for clarity, through a completed joint.
  • FIG. 1 DESCRIPTION OF THE PREFERRED EMBODIMENT
  • two inner conductors, la and 1b are stripped of all covering for a sufficient distance to allow them to be inserted into an inner metallic sleeve 2.
  • the sleeve has an inner indented surface, readily obtained by running a suitable tap through it, which bites into the inner conductors when the sleeve is crimped onto them.
  • an outer metallic sleeve, 3a and 3b is placed on the end of each core to be jointed and slid over the outer conductor 4a and 4b, and a reinforcing metal sleeve 5a and 5b, which just slides on the dielectric spacer, 6a and 6b, is pushed under the outer conductor.
  • the sleeve 2 is then crimped onto the inner conductors 1a and lb.
  • a dielectric spacer 8 as shown in FIGS. 1 and 3, is put around the sleeve, preferably a piece of that spacer that was removed when the inner conductors were bared, and held in place by any suitable means.
  • two outer metallic jointing shells 7x and 7y are positioned about the sleeve, these shells having narrow portions which fit onto the outer conductors 4a and 4b where the reinforcing sleeves have been inserted, and wide portions which enclose the jointed inner conductors and sleeve.
  • FIG. I and FIGS. 2a, b, c which are plan, side, and end elevations, respectively, of one shell
  • the shells are symmetrical about a plane through the axis of a straight length of cable and parallel to it.
  • the two shells are identical and when in position form a tube with a midsection of larger diameter than the ends.
  • the outer sleeves 3a and 3b are slid over the narrow ends of the shells and crimped, thus locking the shells into position with respect to the inner conductors and sleeve.
  • the joint is then essentially complete, the sleeve 2 on the inner conductors being surrounded by the shells in such a way that the characteristic impedance of the cores is maintained across the joint by suitably proportioning the inner diameter of the enlarged midsection of the shell enclosure to the outer diameter of the inner sleeve.
  • the assembled joint is shown, in section and with the scale much exaggerated for clarity, in FIG. 3.
  • a short length of steel tube is positioned about the joint and fixed there. Any stripped-back screening is then brought up to the ends of the tubes surrounding the joint. Finally, insulation can be applied over the whole of the core exposed in order to make the joint.
  • two shells instead of being as shown in the drawings, are each tubular, having two parts of different diameters, so that when the two parts of larger diameter are butted together the shells form a similar enclosureto that formed by the shells illustrated.
  • the enclosure could be made of more than two shells, say three similar shells, each substantially 120 at the center of the enclosure. This is feasible but not practical as the more shells there are to assemble into an enclosure the more difficult the assembly becomes. Therefore, two is the preferred number of shells.
  • a jointing arrangement for a coaxial cable core comprising a pair of cable ends including a pair of adjacent inner conductors, dielectric spacers surrounding said inner conductors at a distance from said ends, a pair of outer coaxial conductors around said spacers, an inner metal-sleeve about the ends of said inner conductors, a dielectric sleeve about said inner sleeve, a pair of reinforcing metallic sleeves around respective said dielectric spacers adjacent each end, said outer coaxial conductors surrounding said reinforcing sleeves,
  • a plurality of like outer metallic tubular shells positioned to form a tubular enclosure about the adjacent inner conductors and inner sleeve, said tubular shell enclosure having a larger diameter midsection spaced from said dielectric sleeve and having narrower diameter outer ends, said outer ends of said enclosure encircling the respective ends of said outer coaxial conductors over said reinforcing sleeves, and a pair of outer metallic sleeves surrounding respective said outer enclosure ends, said outer sleeves being crimped to lock the tubular shell enclosure in position relative to said inner and outer conductors, the ratio of the inner diameter of said midsection of said tubular enclosure surrounding said inner conductors and inner sleeve to the outer diameter of said inner sleeve being selected to maintain the characteristic impedance of said inner and outer coaxial conductors.
