Abstract
Abstract A connector element for electrical devices and the like comprising: a conductive sleeve having an expansible core receiving portion including a wall; a core of elastic material under compression received in the core receiving portion and exerting an expansion force on the wall of the receiving portion when residing therein; the sleeve being of a material harder than and substantially less compressible than said core material. The sleeve being normally expanded by the pressure of the material under compression so that when mated with its cooperating connector element, the sleeve will grip the cooperating connector element affording positive connection and wipe at all times regardless of the number of connects and disconnects made.
