DEFINITION

Classification: 439/645

Combined with push-pull-coupling receptacle:

(under subclass 642) Device wherein the single unitary structure, in addition to having embodied therein the plug with the externally disposed screw-thread-coupling contact, also has embodied therein a plural-contact coupling part in the form of a receptacle adapted to receive within the interior portion thereof at least a portion of a complementary plural-contact plug, the receptacle and its complementary plug being intended to be engaged and coupled together solely by linearly pushing the one coupling part directly toward the mating coupling part, and the receptacle and its complementary plug being intended to be disengaged from one another solely by linearly pulling the said one coupling part away from the mating coupling part in the direction opposite to the direction of the coupling motion.
