DEFINITION

Classification: 439/647

Receptacle having internal screw-thread-coupling contact combined with plug having spaced, longitudinally engaging, pronglike contacts:

(under subclass 641) Device wherein the plural-contact coupling part having the screw-thread-coupling contact further comprises a receptacle, and wherein the screw-thread-coupling contact is adapted to receive therein or therebetween the externally disposed screw-thread-coupling counter-contact carried by a complementary plural-contact plug, so that the receptacle may be screw coupled with and thereby electrically joined to a mating plural-contact plug, having a complementary screw-thread-coupling counter-contact externally located thereon; and wherein the single unitary structure also has embodied therein a plural-contact coupling part in the form of a plug having extending therefrom at least two spaced, elongated, fingerlike contacts for being slidingly engaged along the longitudinal axes thereof by at least two correspondingly spaced counter-contacts of a complementary receptacle, the longitudinal axes of the fingerlike contacts are disposed parallel to the longitudinal axis along which the plug or its complementary receptacle is intended to be pushed toward and thereby coupled to the other.

(1) Note. The screw-thread-coupling contact of the receptacle either may be located within or may form the plug-receiving recess of the receptacle.

(2) Note. Usually, the screw-thread-coupling contact is a cylindrically hollow member having screw-threads formed on the interior surface portion thereof.
