Definitions

  • the present invention relates to a jointing sleeve provided with moment screws for splice connections in electric cables, said jointing sleeve comprising a housing, both ends of which are provided with quill-shaped spaces for receiving the ends of cables to be connected.
  • the invention relates also to a branch-wire connector, comprising a housing provided with reception slots for wires, one or more C-shaped clamping pieces, the ends of which are in line with the slots of the housing, and one or more clamping screws for tightening the clamping piece or pieces toward the housing, the wires thereby pressing against the walls of the slots.
  • Such connectors for branch wires are known to have a problem in terms of corrosion, particularly when connecting branch wires of copper with main cables of aluminium.
  • the connector which is typically made of aluminium, must be tin-plated. The same problem applies also to the above-mentioned jointing sleeve connections.
  • the jointing sleeve shown in fig. 1 is manufactured from a streamline tubing, both ends of which are provided with quill-shaped spaces 5 for receiving the ends of electric cables to be connected as extensions of each other.
  • a pressure-proof partition 2 which is made from a loose disc whose middle section is pressed (flattened by pressing) after the insertion, such that the disc rims have expanded tightly against the inner surface of the sleeve aperture.
  • moment screws 4 On either side of the partition 2 there are two pieces of tapped holes 3 for moment screws 4. As the moment screw 4 is driven against the end of a wire or cable present within the sleeve, the head of the moment screw 4 breaks off upon reaching a sufficient tightness. If the metal of a wire to be connected is soft, the end of a moment screw deforms the wire and displaces some of the wire material, whereby the cross-section of the wire may become too small.
  • loose quill 6 can be aluminium or soft annealed brass, which has a tin coating.
  • the loose quill 6 has a bottom 6b which is preferably solid for further protection against corrosion.
  • the quill 6 may have a conically flaring mouth 6a for facilitating the insertion of the end of a wire into the quill 6.
  • the branch-wire connector shown in fig. 4 comprises a housing 7, which is provided with reception slots 8 for wires and to which is secured one or more C-shaped clamping pieces 9 by using one or more clamping screws 11.
  • the clamping piece 9 has its ends 10 in line with the housing slots 8, the ends of wires to be connected or branched pressing against the walls of the slots 8 as the clamping piece 9 is tightened toward the housing 7 by means of the clamping screw 11.
  • a loose quill 6' is fitted around the end of the copper wire, and the wire end, along with its loose quill 6', is placed in the slot 8.
  • a proper material selection for the loose quill 6' can be used for eliminating corrosion without having to tin-plate the entire connector.
  • the connector is made of aluminium and used as a connector between two copper wires, the loose quill 6' is placed in both slots 8 around the ends of wires to be connected.
  • the loose quills 6 or 6' are manufactured in a plurality of diametral sizes to comply with the diameters of standard dimensioned wires, such that the wire can be readily inserted inside the quill 6 or 6'.
  • the loose quill 6, 6' has a length which covers a necessary connection zone and, e.g. in the case of fig. 4, extends over the entire length of the slot 8, and preferably slightly beyond the end edges of the slot 8, in order to avoid a direct contact between the connector and the wire.
