ABSTRACT:
A wire-fastening mechanism has a wire shaping and guiding device and a pivoted hook-shaped needle which co-operate together to fasten a wire to a connector lug by forming a cross loop of wire through a triangular formation of apertures in the lug. The wire shaping and guiding device has two opposed members between which the lug is inserted. Wire guiding grooves are provided in the opposed members to define one and a half turns of a helical channel around which wire is pushed to thread the aperture lugs as the wire passes between wire guiding grooves of the opposed members. The hook-shaped needle receives the leading end of the wire after it has passed through the triangular formation of apertures. Pivoting of the needle draws the leading wire end beneath a run of the wire between two of the apertures thereby to form a cross loop of wire.
