Electric connection terminal for wires that are not prior-stripped

Claim 1

An electrical connection terminal for power transport wires each constituted by a multi-strand conductor within insulation, said terminal comprising a rigid body provided with at least one threaded or tapped tubular end crossed transversely and at least in part by a wire-passing opening which is elongate in shape parallel to the longitudinal axis of said tubular end and whose width corresponds to a maximum diameter wire to be connected, together with a stopper including a central pusher and screwable onto the end of said tubular end, thereby closing said end, the central pusher moving into the tubular end progressively as the stopper is tightened, said terminal also including at least one conductive spike having perforating end point projecting from a common wall, each point passing through the bottom of a wire-passing opening in one of the tubular ends for the purpose of enabling said spike to interconnect respective wires fixed in each end against the common wall within a tubular end into which the wire under consideration is engaged and in which it is fixed by a stopper whose central pusher arrives, when the stopper is screwed home, close to a perforating point with which said stopper is in alignment, said central pusher causing a wire to be pressed against the perforating point in alignment with the stopper by applying lateral pressure to the wire until said perforating point perforates the insulation and penetrates to come into contact with the central conductors strands of the wire, said terminal further comprising: two tubular ends respectively provided on opposite sides of the common bottom wall with said tubular ends including respective wire-passing openings, said spike projecting on opposite sides of said common bottom wall into said openings and being situated on the alignment axis of said tubular ends, a body provided with at least one hollow tubular end whose wire-passing opening is delimited by two diametrically opposite longitudinal notches disposed symmetrically about a longitudinal mid-plane through said end, and further including a body provided with at least one tubular end having an outer thread which is provided on its inside with two diametrically opposite ribs disposed symmetrically about a longitudinal mid-plane perpendicular to the longitudinal mid-plane about which the longitudinal notches are symmetrical, said ribs serving in a first portion to center a wire to be connected relative to the perforating point of the spike which is disposed between them, and participating in a second portion in wedging said wire engaged on said perforating point.
