Definitions

  • the present invention relates to a branch joint for electrical cables, in particular for branching a low-voltage four-pole main cable with a bipolar or four-pole branch cable.
  • Joints of this type are already known, in particular from EP-0.763.872 conceming a branch joint which however has the following main drawbacks: such joint is unsuitable to be laid underground, being not watertight, unless resin is poured about said joint, resulting in the drawback of a longer installation time, higher cost of the components, longer assembling times and possible ecological problems due to the presence of resin in the ground.
  • the object of the present invention is to eliminate the above-mentioned drawbacks by providing a joint having the following advantages: full immersion-proof watertightness of the joint, hence adapted to be laid underground without being coated with any protective finish and cost reduction due to the significant reduction of the constituent parts and accordingly of the assembling times.
  • the branch joint in question comprises an external body 1 subdivided into sectors, each containing all the members designed to connect the multipole main cable 2 with the phase conductors 3a, 3b, 3c, 3d of a branch cable, with the peculiarity of having each sector composed of contacts 14 and 15 which, through piercing members 4, 16, 17 connect the phase conductors 5, 6, 7, and 8 of the main cable with the phase conductors of the branch cable.
  • the main novelty of such joint consists in that, fitted at the stripped area of the extemal surface of the main cable 2 affected by the piercing members 4 is a sealing rubber sheath 9 with sealing compound interposed between cable and sheath and in that said contacts 14 and 15 are disposed into an insulating container 10 integral with a rubber hood 1 which is fitted on each of the phase conductors 3a, 3b, 3c, 3d, said hoods converging in a single hood fitted on the branch cable not shown in the figure.
  • said contacts 14 and 15 are mechanically connected with a manual operating screw-bolt and all insulating containers 10 are inserted into seats of the sectors of body 1.
  • said container 10 is provided with a sleeve 13 fixed to which is the rubber sealing hood 11.
  • rubber in the present description, as well as in the following claims, should be interpreted in a broader sense; in other words, “rubber” will mean not only rubber but also materials having the same known properties and characteristics of resilience, flexibility, elasticity, wear and tear resistance, pliability, fluid tightness, etc.
