DEFINITION

Classification: 439/660

Plural-contact coupling part comprises receptacle or plug:

(under subclass 626) Coupling part either (a) in the form of a female coupling part denoted as a receptacle which has its contacts located within the interior portion thereof, which receptacle further is adapted to have its contacts receive the counter-contacts located within the interior portion thereof, which receptacle further is adapted to have its contacts receive the counter-contacts either protruding outwardly from or externally disposed on a complementary male coupling part denoted as a plug whenever the receptacle is coupled to the mating plug; or (b) in the form of a male coupling part denoted as a plug which has its contacts either protruding outwardly therefrom or disposed on the exterior surface thereof, which plug further is adapted to have its contacts received by the counter-contacts located within the interior portion of a complementary female coupling part denoted as a receptacle whenever the plug is coupled to the mating receptacle.
