Definitions

  • This invention relates to a one-piece branch connector, especially for live power lines.
  • low voltage electric current distribution lines generally consist of several twisted insulated cables, generally called “twists”, or “preassembled bundles”. From these twisted insulated cables, there are provided taps, intended to supply connections serving the subscribers. These connections are made using mechanically tightened branch connectors.
  • branch connectors currently used require, for their installation on the main line, the stripping of the main cable over a precise length, which requires a lot of time and attention on the part of the fitter. Then, after fitting the connector, it is necessary to cover it using a protective device, called a "gusset" or insulating cover. The various operations which are carried out under voltage therefore require a lot of precautions.
  • connectors are known, more recent, which can be put in place without prior stripping of the main cable or of the derived cables, the electrical contact between the twist and the derivatives being produced using a perforation system. insulation, com bearing teeth or blades, provided on the connector, and which comes to bear on the metallic core of the live cable through the insulation thus perforated.
  • the connectors of this type currently used are distinguished from each other either by their mode of implementation, or by the quality of the sealing of the perforations and the dielectric insulation of the connector.
  • This invention proposes to make improvements to current connectors, by providing a one-piece branch connector with insulation perforation, characterized in that it comprises: a housing made of insulating material with high mechanical resistance, receiving a connecting piece of material electrically conductive, this connecting piece comprising blades for perforating the insulators of the conductors to be connected and housings receiving the derived lines, in which the tightening screws of the derived conductors engage; an insulating and sealed cover for said housing, and a clamping clamp made of insulating material which is positioned on said housing, the clamping of the clamp on the main conductor placed in the housing being ensured by a torque limiting screw, the stirrup resting on a rear surface forming an axis of articulation between the stirrup and the housing, and the tightening on the derived lines being effected by means of an insulating screw
  • said insulating screw driver is of the type described in French Patent No. 86 01 104, filed January 27, 1986 by the present holder.
  • its end intended to come into contact with the branch line comprises a central recess in the form of a bowl, making it possible to cut a crown in the insulation of the branch line, in order to transmit the tightening force by the core wire.
  • the sealing and the dielectric isolation of the connector are ensured by the housing made of insulating material, by its cover made of flexible and insulating material, which completely covers the housing and the connecting piece, by the 'coach made of insulating material for tightening screws of derived lines, and by insulators of the main conductor and derived lines.
  • the cover of the casing comprises housings in the form of gains, intended to receive the ends of the derivative conductors to be connected, these housings being able to be closed by means of tight protective caps.
  • the connector which is the subject of this invention has the appearance of a part made up of two main elements: on the one hand, a housing 10, and, on the other hand, a clamping bracket 20.
  • the housing 10 is made of an insulating material with high mechanical resistance, and it comprises an electrical connection piece 12 of good conductive metal, provided with blades 14, 16, or the like, to ensure the perforation of the insulators of the main conductor P and of the derived lines D.
  • This electrical connection part 12 also includes housings 21, receiving the derived lines such as D, these housings being delimited in the upper part by a partition 22, provided with tapped holes intended to receive the threaded rods of the screws. tightening of derivative conductors.
  • These clamping screws of the type with insulating coach are of the type described in French Patent No. 86 01 104, mentioned above.
  • each threaded rod 26 has a central recess 40, defining a crown 42 ( Figure 1).
  • the housing 10 and the connecting piece 12 are covered with a cover 18 made of flexible and insulating material, which provides sealing around the perforation zones of the insulators of the main conductor P and the branch lines D, as well as the dielectric insulation of the connecting piece 12, thanks to the parts 18 ⁇ in the form of soles of the cover, interposed between the housing 10 and the connecting piece.
  • the cover 18 includes passages in the form of sheaths, such as 30 (FIG. 2), for the positioning and positioning of the branch lines D in the connector, these passages 30 being able to be further closed using plugs 32 , 32 ⁇ .
  • the clamping bracket 20 is made of insulating material with high mechanical resistance. It is designed so as to ensure tightening on the main conductor using a torque limiting screw 34 and a nut 36 or the like, passages 38 being provided, in this bracket 20, for the screws to insulating drive described above, which ensure the tightening on the derived lines D.
  • the stirrup bears on the casing 10 by a surface 44, which forms an axis of articulation between the clamping stirrup 20 and the casing 10.
  • the stirrup further comprises blades 46, arranged opposite the blades 14 of the connecting piece 12.
  • the connector of the invention can be used either on the main conductor P first, then on the branch lines D, or on the branch lines first, and then on the main conductor. We can therefore proceed as follows: - The connector, lightly greased in the factory at the level of the blades 14, 16, is put in place on the main conductor P, then it is put under tension, by tightening the stirrup 20 using the screw 34; the latter clamps the main line thanks to the teeth 46, the stirrup bearing on the articulation surface 44, and the blades perforate the insulator of the main conductor P; to put the derivatives in place, the caps 32, 32 ⁇ are removed ensuring the protection of the housings 30 and of the derivative lines D, the ends of the branch lines are introduced into these housings, and they are tensioned by tightening the 24-24 ⁇ coach screws which, by pressing the branch lines on the cutting blades 16, ensure the perforation of the insulator of the branch lines .
  • the electrical connection between the main conductor P and the branch lines is therefore effected by the connecting piece 12, the dielectric insulation and the sealing of the live connector being provided by the cover 18 and the transmission members 28, forming insulating elements and seals, and by insulating the various conductors.
