Abstract
An electrical connecting assembly includes a combination of a wire-binding screw and washer for fastening a conductor wire to a mechanical lug. The wire is inserted into the lug within a main bore. The screw and washer are inserted into the lug within a secondary threaded bore. The screw has a threaded body with an external thread for coupling to an internal thread of the mechanical lug. The threaded body has a bottom surface from which a boss extends with an end surface being formed-over for retaining the washer. The washer has a top surface in contact with the bottom surface of the screw and a bottom surface in contact with the conductor. The screw rotates independently of the washer, providing improved clamping force and reduced wire-strand breakage during current cycling.
