Abstract: An electrical connector plug ejector apparatus includes a cogged belt having transverse teeth arranged to mesh with transverse surface grooves on an electrical connector plug. A snap-on cover is arranged to retain the belt to the surface of the plug with the teeth of the belt meshing with the plug grooves and the ends of the belt retained beneath the cover to form the belt into an endless loop above the connector. External electrical connections to the connector are provided by individual wires positioned in respective plug surface channels forming extensions of the grooves and arranged to exit beneath the edge of the cover. The belt provides a flexible handle for ejecting the plug from an associated socket while providing a strain relief for the electrical connections by transferring a retaining force for the belt supplied by the cover to the electrical connecting wires.

Abstract: A slidewire wiper contact has a wiper arm mounted at one end on a rotatable shaft while the other end of the arm carries an electrically conductive support extending past the end of the arm. A free end of the electrically conductive support has attached thereto a plurality of substantially constant outer diameter coils of electrically conductive wire. The coils are arranged in a continuous spiral while the electrically conductive support is attached thereto by a low resistance connection extending along a line on an outer surface of the coils. Electrical connection means are attached to the electrically conductive support for movement therewith during rotation of the wiper arm to maintain an electrical connection to the conductive support.
