A terminal socket assembly for interconnecting electrically powered vehicular components with an associated input male input pin and an output cable. The socket assembly includes a spring cage blank having first and second extending edges and a plurality of spaced apart and angled beams extending between the edges. The spring cage is formed into a substantially cylindrical shape, and particularly in an “hourglass shape”, configuration utilizing any of a variety of different forming and bending operations. A substantially tubular sleeve is provided for receiving the configured spring cage in axially inserting fashion. The sleeve is compressingly engageable, such as by forming an axially extending slit along the length of the sleeve with a predetermined incremental amount of spacing established between adjoining surfaces, and in order to create an interference fit with the axially inserted spring cage. The assembled sleeve and spring cage is capable of biasingly receiving and engaging an extending and inserting portion of the male pin. Gripping portions are integrally secured to the tubular sleeve and fixedly engage an extending end of a cable to electrically communicate the two cables. A sealed connector housing forms a part of and encases the terminal socket assembly and extending connector cables and includes assembleable male and female housing portions and end seals.
