Captive fastener and captive washer assembly

摘要

A terminal assembly is disclosed for effecting connection with an electrically conductive element such as a lead or antenna wire or a spade type terminal mounted to the end of such a conductor wire. The disclosed assembly comprising a screw fastener having a clamping washer mounted thereon, which fastener is engageable with an internally threaded element providing a clamping surface opposing said washer. Said washer is provided with a central aperture, an intermediate section surrounding said aperture and an axially extending clamping flange. The intermediate section of said washer includes an inwardly tapered segment which is engageable against abutment means on the fastener shank, which abutment means and the driving head on said fastener serves to limit the movement of the washer relative to the fastener shank. Accordingly, movement of the fastener relative to the support surface will produce almost immediate movement of said washer relative to said support surface.
