  • the object of the present invention is to simplify these connection devices, while improving electrical connection and protection electric.
  • the invention thus relates to a device for electrically connect a main electric cable with a busbar and / or with one or more secondary cables, these cables having a core conductive surrounded by an insulating sheath, the device comprising at least two serrated jaws with teeth arranged opposite one another, to tighten the main cable and pass through the sheath insulating to come into contact with the conductive core, and means of electrical connection with the bar conductor and / or secondary cables.
  • this device is characterized in that it comprises a metallic element made in one piece by cutting and folding a conductive metal sheet, this element comprising the serrated jaws and being arranged in a block in insulating material from which the teeth of the jaws, this block being covered by at least one other block of insulating material, clamping means being provided for clamping said other block on the main cable spanning the jaws, and in that both jaws are connected to each other by a strip of the cut sheet.
  • the one-piece cut element ensures thus simultaneously the jaw functions coming in taken with the core of the cable and of the body ensuring the electrical connection between the conductor (s).
  • each jaw engaging with the main cable includes two parallel series teeth.
  • the electric current from the main cable can be transmitted, either to a busbar by a track bolted flat, either by serrated parts of the piece cut from the same metal plate, formed in jaws, which allow cables to be clamped secondary derivation.
  • An additional hole is provided in the room cut in an accessible location to allow connection with a bolted terminal, a flying cable for temporary connection or recharge.
  • a hole additional 32 is also shown to connect by bolting the terminal of a connection cable temporary or recharge.
  • This hole can also advantageously be placed in 32a, to allow a better accessibility, and easier connection provisional.
  • the holes 38 are used for the passage of a jaw tightening bolt.

  • Block 11 above is covered by one or more other blocks 12, 13 in insulating material.
  • Clamping means such as screws 14, 15 are provided to tighten the blocks on the cables 1, 2 extending over the jaws 6, 7.
  • the metallic element 10 comprises a second serrated jaw 6a, the teeth 8 of which are located opposite the teeth 8 of the first jaw 6.
  • These two jaws 6, 6a are connected to each other by a strip 16 of the sheet metal cut advantageously from arched shape.
  • This strip of cut sheet metal can also be non-arched shape as shown in Figure 10.
  • each jaw 6, 6a intended to come into engagement with the main cable 1 includes two parallel series of teeth 8.
  • the metallic element 10 includes four jaws 6, 6a engaging with the main cable 1, two of them 6 being located in the foreground and the other two 6a in the foreground parallel to the first.
  • the space between the two pairs of jaws allows cable insertion 1.
  • the two jaws 6 located in the first plan include a first set of teeth 8 located in the plane of a longitudinal strip 17 and a second series of teeth 8 located in the plane of a portion of strip 18 parallel to the longitudinal strip 17 and connected to the latter by a transverse strip 19.
  • the two jaws 6a located in the second plan include two sets of teeth 8 each located in the plane of a portion of strip 20.
  • the two strip portions 20 are connected on the one hand by a transverse strip 21 and on the other hand by the arcuate strip 16 which connects each of these jaws 6a to each of the jaws 6 located in the foreground.
  • a single strip 16 connects the serrated jaws together.
  • each longitudinal strip 17 carries to a certain distance from jaw 6 engaging with cable main 1, a jaw 7 engaging with a secondary 2 cable extending in the direction elongation of the longitudinal strip 17.
  • the jaws 17 come from other areas of the conductive element in depending on the possibilities of cutting and chosen location of cables after folding this conductive element.
  • the jaw 7 engaging with a secondary cable 2 is formed on a corrugated end 17a of the strip longitudinal 17.
  • the bands longitudinal 17 and the strip portions 18, 20 are housed in slots made in blocks 11, 12, 13, pressed against each other.
  • Figures 8 and 9 show in plan element 10 cut from a metal or alloy sheet good conductor of electricity.
  • Figure 10 shows another version of production of an element cut from a sheet.
  • element 10a includes one of its ends two sets of parallel teeth 8a perpendicular to a strip 25 which is extended by a band 26 folded towards the two sets of teeth 8a above.
  • This folded strip 26 is itself bordered by teeth 8a arranged opposite the two series of teeth 8a above.
  • the strip 25 is extended by a widened part 27 in which are cut laterally blades 28, 29, 30 each carrying two series of teeth 9a bent perpendicular to these blades.
  • Figure 11 shows a top view of a insulating module 36 for cable connection, made at starting from the cut element 10a shown in the figure 10. This module allows you to connect a main cable 1 to three secondary cables. An insulating cap 37 protects access to hole 32.
