Definitions

  • This invention relates to cable jointing, particularly but not solely for telecommunications cables.
  • One form of cable jointing kit which has been proposed comprises a length of tubing to enclose the cables over the jointing zones, and two heat-recoverable end members for fitting to the opposite ends of the tubing and embracing the respective cables upon recovery.
  • the end members have cylindrical portions which fit closely within the end of the tubing and, in accordance with one proposal, a sealing compound (e.g. an adhesive) is injected into such clearance as exists between the inner surface of the tubing and the outer surface of the inserted end member.
  • a sealing compound e.g. an adhesive
  • a cable jointing kit comprising a length of tubing and two heat-recoverable end members having cylindrical portions for fitting into the opposite ends of the tubing, at least one annular groove being formed in the interfitting surfaces of the tubing and/or each end member cylindrical portion, which grooves serve to receive a substance to form annular seals between the two end members of the tubing.
  • the outer surface of the cylindrical portion of each end member is formed with a series of interconnected annular grooves.
  • the grooves guide the injected compound and ensure that it will form at least one complete annular sealing ring, and usually several such rings.
  • the end members are a locking fit into the opposite ends of the length of tubing, by virtue of annular ribs on the cylindrical portions of the end members engagingwithin annular grooves in the inner surface of the tubing adjacent its ends.
  • a method of jointing cables in which the cables to be joined are threaded through respective heat-recoverable end members and one of the cables is threaded through a length of tubing, then the cables are joined, the tubing is slid along the cables and positioned around the joined cable ends, the end members are slid along the cables to fit cylindrical portions of the end members into the opposite ends of the tubing, tubular portions of the end members are heat-recovered about the cables and a sealing substance is injected into annular grooves which are formed in the interfitting surfaces of the tubing and/or end member cylindrical portions, so as to form an annular seal between each end member and the tubing.
  • the embodiment of cable jointing kit which is illustrated comprises a length of tubing 10 (which may be formed of metal or plastics material or a combination of metal and plastics), and two moulded end members, one such end member 12 being shown.
  • the end member provides an end closure wall having at least one cable sleeve 14 projecting in one djrection (to project outwardly from the joint), and a short cylindrical or tubular portion 16 projecting in the opposite direction, for fitting into the end of the tubing 10.
  • a conical tapering entry surface 11 is formed on the tubing end to mate with a conical surface 17 on the end member: adjacent the tapering surface 11 the tubing is formed with an annular groove 13 which is to receive an annular ridge 18 on the end member.
  • the end of the tubular portion 16 of the end member is formed with another annular ridge 19, to be received within an annular groove 15 in the tubing, the extreme end surface of the portion 16 being formed as a conical tapering surface which provides the forward side of the ridge 19,
  • the cables to be joined are threaded through the respective end members and one of the cables is threaded through the tubingi then the cable ends are joined, the tubing slid along the cables into position over the joined cable ends, and the end members slid along the cables to fit into the opposite ends of the tubing so that the cable joint is enclosed.
  • the ridges 18 and 19 of each end member snap-fit into the corresponding grooves 13, 15 of the tubing 10 to provide a mechanical lock.
  • the sleeves are then heat-recovered so as to shrink down to embrace and seal around the cables.
  • the clearance between the tubing inner surface and the tubular portion 16 of each end member now comprises the series of interconnected annular grooves 20.
  • a sealing compound is now injected into this clearance space through one or more apertures provided through the tubing wall.
  • the compound may comprise a curable liquid resin or polymer and preferably an adhesive: the grooves 20 guide the flow of injected compound and ensure that several complete annular rings of such compound are formed between the end member and the tubing, so as to ensure the required seal.
  • the jointing kit will comprise, in addition to the length of tubing and two end members, a quantity of the sealing compound and a device for injecting this into the grooves 20.
