DEFINITION

Classification: 439/661

Having screw-thread-coupling contact:

(under subclass 660) Coupling part having 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 mating counter-contact, so that the coupling part may be screw coupled to and thereby electrically joined to a mating plural-contact counterpart carrying a mating 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 the screw threading on a cylindrical or annularily-shaped contact, is also included in

this and the indented subclasses.

SEE OR SEARCH THIS CLASS, SUBCLASS:

14, for a connector having a swivel joint between a conductor and a screw-type contact shell.

253+, for a coupling part adapted to be coupled to a mating connector, whereby one of the connectors is screw threaded, and the couple is engaged or disengaged without rotary motion.

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

615, for a connector having a screw-thread-coupling contact combined with a vitreous-type envelope. 641+, for a single unitary device having two or more plural-contact coupling parts embodied therein and in which at least one of the coupling parts has a screw-thread-coupling contact.

659, for a receptacle having separate through-passageways for securing intermediate portion of conductors thereto and having a screw-thread-coupling contact therein.
