DEFINITION

Classification: 439/641

Unit includes coupling part having screw-thread-coupling contact:

(under subclass 638) Device wherein at least one of the plural-contact coupling parts contained within the unitary structure carries a contact which either has screw threads formed thereon or has equivalent screw-thread-engaging means thereon which cooperates, by means of a relative screw motion therebetween, with screw-threads or screw-thread-engaging means formed on a mating counter-contact, so that the coupling part may be screw coupled with and thereby electrically joined to a mating, plural-contact counterpart carrying a screw-thread-coupling counter-contact.

(1) Note. A document which discloses solely a device encompassed by the subclass definition set forth herein, but which fails to specifically claim screw-threading on an annularily-shaped contact shell, is also included in this and the indented subclasses.

296+, for coupling part adapted to be screw-thread-coupled to a mating counterpart, but in which the screw-thread-coupling means is not formed on a contact.
