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.

Abstract: A sealed electrical connector comprises an electrically insulated pin housed in a receptacle and has a bared end for contact with a conductor extending partly out of the receptacle. An adjustable mechanical means is provided establishing such contact. A deformable resilient sleeve serves to seal the connection between the pin and receptacle, and access to the mechanical means is only possible through one end and along the sleeve which serves thus to seal the mechanical means.The connector is suitable for use with an implantable cardiac stimulator.

Abstract: A portable, prefabricated panel adapted to be connected with a plurality of similar panels to form a wall or partition structure. The panel is electrically prewired and includes electrical power blocks disposed adjacent the opposite lower corners of the panel, which power blocks are connected by electrical cables which extend internally of the panel. When two or more panels are connected together, electrical power is transmitted between each adjacent pair of panels by a flexible electrical connector which plugs into the power blocks of the adjacent panels. The panel also has electrical sockets integrally associated therewith, which sockets are preferably associated with the power blocks. The power blocks are symmetrical so that the same electrical connections can be made on either side of the panel. A channel-like raceway extends along the bottom edge of the panel for permitting the hidden storage of communication cables.
