ABSTRACT:
The present invention relates to the connection of insulated electric wires, and it pertains more precisely to a terminal and a connection block for electrically connecting two insulated wires without prestripping them. Prior art connecting devices that operate without prestripping are usually in the form of a flat spring, cut in a U shape, the branches of which define a slot. In such devices, the insulated wire to be connected is introduced at the end of the slot adjacent the free ends of the branches. This type of device has a disadvantage since the perforation of the insulation is made where the deformation of the branches is the easiest. The self-stripping connecting device of the present invention is constituted by a flat spring including a portion forming a U, the branches of which are elastically biased one against the other, and an opening to allow the introduction of the insulated wire at the end of the slot adjacent the base of the U. Additionally a connecting block is disclosed which comprises an insulating box having at least one bore for receiving an insulated wire, and a movable element having a connecting device and being movable from a first position in which an inserting opening of the connecting device is in line with the bore, toward a second position in which the end of the slot remote from the opening is in line with the bore.
