DEFINITION

Classification: 439/306

Threaded coupling part:

(under subclass 304) Coupling part including a helically ribbed portion adapted to interfit with a portion of the mating part by relative rotation and corresponding axial advance.

(1) Note. In this and the indented subclasses, the means to forcibly bring the parts together or the means to maintain interengagement may comprise structure actually stamped from a contact and still integral therewith wherein the intended use of that structure is to hold the parts together such that a specially designed implement or a special manipulation is required for separation of the parts.

277, for a threaded coupling part with a sealing element or material for cooperation with a coupled connector.

665, for an insulated, plural contact electrical connector having an irregular, interrupted or discontinuous screw thread contact; wherein such irregularities are to increase friction with the groove of a mating connector.

735, for an insulated electrical connector having an

irregular, interrupted or discontinuous screw thread contact; wherein such irregularities are to increase friction with groove of a mating connector.
