BORNE DE RACCORDEMENT DE FIL ELECTRIQUE SANS DENUDAGE

摘要

The insulated wire (4) is inserted into an insulating housing (1) through a circular entry hole with an axial guiding slot (110) leading from it. The end of the wire is lodged in a box (22) attached to a sliding unit (2) which can be moved axially within the housing. A metallic rectangular frame (3) has an axial slit units upper face which has sharpened bevelled edges and a shaped convex mouth adjacent to the wire to guide it into the slit. When the slider unit is pushed home, the frame bows and the sharp edges cut through the insulation to the central conductor. The guiding slot (110) has upper and lower sections. The upper section has a gap slightly larger than the outer dia. of the wire and the lower section has a gap less than the insulation dia. to grip the wire. A tool (5) with a narrow blade locates a cavity in the slider box and a rotation action about the edge of the entry hole produces the translation motion.
