Abstract
A two-piece socket terminal is crimped to the end of an ignition wire and detachably connected to a spark plug stud terminal. The terminal comprises an attachment member of crimpable semi-hard steel having a corrugated channel at one end and a tee-shaped support at an opposite end, and a socket member of spring tempered steel having a split sleeve at one end and a longitudinal tongue at an opposite end. The attachment and socket members are secured to each other by clamping arms of the tee-shaped support bent over the longitudinal tongue. The tongue has circumferential tabs behind the clamping arms providing a mechanical interlock in the pull-off direction while the foremost internal rib of the corrugated channel provides a stop in the push-on direction. The terminal provides a direct electrical connection between the ignition wire conductor core and the socket piece which is enhanced by forward projecting tabs of the corrugated channel. In-line and angled embodiments are disclosed.
