Definitions

  • the invention relates to the connection of insulated electrical cable with insulation perforation, in particular the connection of a branched conductor to a main cable.
  • Connection or branching means are known for electrical cables insulated by a layer of plastic material where the contact between the conductor (s) is established by forced perforation of the insulating layer by means of a conductive metal body external to the cable and comprising suitable asperities capable of passing through the insulating layer of the cable (s).
  • These devices generally include a cage or stirrup, possibly removable, enclosing in its interior the electrical cable or cables at the place where the forces required to exert the roughness of the intermediate metallic body will have to penetrate through the insulating layer. and thus establish the connection.
  • This intermediate conductive body, the opposite face of the cable is provided with teeth often cut in its mass, is asked to play the double role, of means for piercing the insulating layer, of receiver and transmitter of the necessary mechanical thrust for this piercing as well as for the collector of the electric current coming from the various asperities arrived in contact with the underlying conductor.
  • the known devices for electrical connection by perforation of insulation do not include a simple means of controlling the perforation of the insulation. On the other hand, the seal is poorly or not ensured.
  • An object of the invention is to 'provide a connection device carrying out a control of the perforation stroke of the insulation to avoid deterioration of the cable strands during excessive tightening of the fixing screw and this whatever or the section of the cable in a determined range.
  • Another object of the invention is to provide an isolated and watertight connection device whatever the section of the cable in a determined range.
  • the subject of the invention is an insulated cable connection device by perforation of insulation comprising jaws provided with teeth for perforation of insulation during the introduction of the cable into the connection device, characterized in that he comprises two jaw-shaped parts intended to grip the cable and provided with snap-fastening means which hook onto one another to position the connection device on the cable by simple snap-fastening and perforation means d insulation with screw tightening and limited travel to perforate the cable insulation until the teeth contact the conductive strands of the cable.
  • the cable connection device comprises a watertight housing in two parts 11, 12 which can be joined by a rod 10.
  • the lower part 11. contains a fixed jaw 13 having a fixed toothing 14;
  • the upper part 12 contains a movable jaw 15 which encloses a movable toothing 16 movable inside the jaw 15 by means of a screw 17 comprising a screw head 18 covered with an insulating plug 19.
  • the movable jaw 15 is provided with two arms 21, 22, the notched end 23 of which is intended to hang in notches 24 of the fixed jaw 13.
  • the movable teeth 16 is provided with lateral arms 25, 26 intended for slide along the body of the fixed toothing 14 when tightening the screw 17.
  • the two teeth 14 and 16 are placed on the main cable 27 and penetrate into the insulator 28 of the cable when the screw 17 is tightened (see fig. 4).
  • the tightening stroke of the screw 17 is limited by two stops 29, 30 carried respectively by the arms 21, -22 of the movable jaw 15 and by the movable teeth 16 which serve as end of stroke stops.
  • the tightness of the housing on the cable 27 is ensured by tongues 31, 32 of the upper part which are nested in a tongue 33 of the lower part 11.
  • the tongues are terminated by lips 34 which rest on the cable insulator (fig. 5).
  • the derivative conductor 35 is placed in a housing 36 formed in the fixed jaw 13 and tightened by a screw 37 carrying a head 38 protected by an insulating plug 39.
  • the sealing of the derivative conductor 35 is ensured by a perforated cap 41, the lip 42 on the edge of the perforation resting on the conductor insulation.
  • the housing is made of insulating plastic, for example polyamide or PVC.
  • the metal parts for different mechanical and electrical reasons are made of a material having good electrical and mechanical properties, for example aluminum alloy which will be subjected to a thermo-chemical treatment to give it greater mechanical hardness.
  • the originality of the case lies in the sealing system around the main cable regardless of its section.
  • the rounded, double-walled shape of the sealing tabs on each of the parts is suitable for different cable sections, for example between 16 and 70mm 2 .
  • the insulating caps covering the screw heads make it possible to make the connection device completely insulated and therefore to undertake an installation under electric voltage.
  • the tightening stroke is constant thanks to the stops 29, 30 regardless of the cable section and the value of the tightening torque. This reduces the risk of damage to the cable strands.
  • the notches 23, 24 of the jaws 13 and 15 make it possible to compensate for the differences in cross section of the conductors.
  • Figures 6 and 7 show two variants of cable connection device to a branched conductor in the case of a cable with three separate conductors 41, 42, 43 each insulated by an insulator 28, it being understood that such a device can be used for more drivers.
  • a connection device is placed on each separate conductor.
  • the derivative conductor is placed in a housing 46 formed inside the movable teeth 16.
  • the clamping of the derivative conductor 35 is obtained by a screw 47 placed inside the clamping screw of the main cable 17 which is produced in the form of a hollow cylinder, or by a screw 47 fixed on the movable teeth 16.
  • the implementation of the invention makes it possible to obtain a fully insulated electric cable connection device for working under electric voltage and waterproof, with a snap-in system facilitating its assembly and allowing its use for a large range of cables of different sections, and with insulation perforation at constant value by limiting the movement of the movable jaw.
