Interconnection of two electric cables

A device for interconnection of two multi-strand cables intended for the distribution of electrical energy, said multi-strand cables including an output cable having a plurality of first active wires each being surrounded by an insulating sheath and an input cable having a plurality of second active wires projecting in at least one plane and being parallel to one another, said second active wires each being surrounded by an insulating sheath and all by a common outer sheath,

• said device comprising, a box made in two interfitting halves, a first half of said two interfitting halves engaging the output cable and a second half of said two interfitting halves engaging the input cable, and an intermediate interconnection plate positioned in the box between the output cable and the input cable,
• said plate comprising, in a number at least equal to the number of pairs of wires to be respectively connected from the output cable and the input cable, one or more pairs of metal conical points permanently incorporated in said plate in a transverse direction to a plane of said plate,
• said pairs of metal conical points each able to pierce insulating sheath of said first and second active wires and electrically connect corresponding wires from said first and second active wires, each pair of conical points comprising a first point projecting from a first face of the plate and a second point projecting from an opposite direction on a second face of the plate, said first point effecting, by pressure, a connection of said first active wires of the output cable and said second point effecting, by pressure, the connection of the corresponding second active wires of the input cable,
• said first half having first grooves to receive and maintain separation of free ends of said first active wires of said output cable engaged thereon,
• said plate having projection bars correspondingly insertable in said grooves to engage said free ends in said grooves when said plate is inserted in said first half and said metal conical points are piercing the insulating sheath on said free ends of said first active wires.
