Female terminal for distribution of electrical current and provided with electrocution-preventing means

Claim 1

Female terminal for electrical current distribution, comprising at least one assembly of at least two female sockets destined to receive as many male parallel pins belonging to a male electrical plug having a predetermined spacing, said female sockets extending parallel to a main axis, the terminal further comprising: (a) a casing made from an insulating material comprising an anterior mounting plate having at least two through-bores for the male pins; (b) a contact support facing the anterior wall, adapted to carry: (i) at least two primary contacts destined to receive said male pins, each of these primary contacts comprising in view thereof two primary contact surfaces mounted in respective register, extending along the pathway of the male pin so as to tightingly enclose the latter, these surfaces being connected to a first secondary contact surface; (ii) at least two secondary contacts, each having, on the one hand, at east a second secondary contact surface and, on the other hand, electrical connecting means at a current outlet, each second secondary contact surface being assembled to be in register with one of said first secondary surfaces of primary contacts and to thus define an assembly of secondary contact surfaces; (c) an insulating connecting blade, positioned between the cavity anterior wall and the contact support, destined to move along said axis while remaining parallel to itself, this blade comprising at least two connecting members each destined to come in simultaneous contact with the two contact surfaces of an assembly of secondary contact surfaces when the blade is in a "working" position, the blade further comprising, in register with the primary contact surfaces of each of the primary contacts, a cavity destined to enable the passage of said primary contact surfaces of the assembly of primary contacts which are in register with the cavity and at least two abutment areas mounted partially in register with said through-bores; (d) elastic means adapted to maintain said blade spaced from its working position until an assembly of male pins is engaged into said sockets; wherein said blade cavities are radially exteriorly oriented, as well as the primary contact surfaces, whereas each abutment area comprises, in register with the associated through-bore, a radially-exteriorly inclined surface.
