Abstract
Abstract In order to prevent the rotation of an electrical contact 30 within a connector assembly housing 3 the contact 30 is provided with a plurality of radial fins 37 which are located within a space between resiliently deflectable fingers 21 which are part of the contact retaining insert 20. Because the contact 30 does not rotate, the winding of a wire around the wire receiving portion 38 of the contact is facilitated.
