DEFINITION

Classification: 439/253

SCREW COUPLING PART ENGAGED OR DISENGAGED WITHOUT ROTARY MOTION:

(under the class definition) Electrical connector comprising a coupling part* having a rib helical about an axis parallel to the direction of connector coupling action, for coupling with a mating part by a helical motion and with helical interfitting with respect thereto, and also having provision to permit coupling or uncoupling with the mating part other than by helical motion.

(1) Note. A member for interfitting with the helical rib of a mating connector is considered to be a helical rib because such a member functions as a helical rib.

(2) Note. Included herein is a device adapted to be coupled to a mating connector by a screwlike operation having means to disable the helical rib to allow disconnection by a longitudinal pulling motion.
