Definitions

  • the invention relates to a cable clamp terminal for connecting conductive cables to an electrical appliance having a clamp-shaped terminal body confining two superimposed housings, each arranged to receive the end of a cable and two screws of tightening capable of being screwed into a threaded orifice of said body extending transversely to said housings, one intermediate of the screws tightening the cable inserted in the lower housing between the bottom of the bracket and the intermediate screw and the other upper tightening the cable inserted in the upper housing between the intermediate screw and the upper screw.
  • the second cable is subsequently introduced and the upper screw wedges the cable between the two screws. After mounting, the intermediate screw is no longer accessible and it is impossible to subsequently check that the cables are properly tightened or to carry out additional tightening to compensate for some compaction of the cable strands.
  • the object of the present invention is to remedy this drawback and to allow the production of a terminal of reduced width for the connection of two superimposed conducting cables allowing subsequent tightening after packing of the cables.
  • the terminal according to the present invention is characterized in that the tapping of the intermediate screw has a longitudinal clearance allowing limited axial sliding of the intermediate screw immobilized in rotation.
  • the internal thread advantageously extends over the entire length of the internal orifice, the corresponding axial clearance of the two screws having no effect on the upper screw.
  • the thread is advantageously square threaded which further reduces the lateral forces exerted on the bracket forming the body of the terminal.
  • a body 10 of a connection terminal of generally parallelepiped shape has a recess 11 of elongated shape passing right through the body 10.
  • the width of the recess 11 is slightly greater than the section of cables 18, 20 to be connected, the height or length of the recess 11 being sufficient for the insertion of the ends of two superimposed cables 18, 20.
  • the bottom 12 of the body 10 is joined and fixed to the upper face of a track 14 of an electrical appliance by a fixing bolt 16.
  • the recess 11 extends parallel to the track 14 and a tapped hole 22, formed in the body 10 , extends perpendicular to the recess 11 along the longitudinal axis of the body identified in Figure 1 by the line II-II.
  • the tapped hole 22 opens on the upper face 24 of the body 10 and is extended at the base by an orifice of reduced section 23 for passage of the bolt 16.
  • the tapped hole 22 receives two clamping screws, an intermediate screw 26 and an upper screw 28.
  • the intermediate screw subdivides the housing formed by the recess 11 into a lower housing receiving the end of the cable 20 and an upper housing receiving the end of the cable 18.
  • the thread of the hole 22 and of the screws 26, 28 is at square thread, the height h of the thread being notably less than half the pitch p, so as to obtain a significant clearance allowing axial sliding of the screws 26, 28 without rotation of the latter.
  • the screws 26, 28 have on their upper face a hexagonal recess 30 for insertion of a tightening tool and on their lower face a pivot 32 for penetration between the strands 34 of the cables 18, 20.
