DEFINITION

Classification: 439/617

Plug having spaced, longitudinally engaging, prong-like contacts:

(under subclass 611) Electrical connector wherein the connector carried by the glasslike body has extending therefrom at least two elongated, fingerlike contacts* which are spaced-apart and electrically insulated one from another, the connector further forms a coupling part* specially adapted to mate and interengage with a complementary counterpart having prong-receiving contacts, so that an electrical joint having at least two mutually insulated electrical paths may be formed, and wherein the longitudinal axes of the elongated, fingerlike contacts are disposed parallel to the longitudinal axis along which the coupling part is intended to be engaged with its counterpart.

SEE OR SEARCH THIS CLASS, SUBCLASS:
