Abstract

A quick-locking male connector includes: an inner contact; an insulator; an outer contact; a spring basket with a plurality of spring fingers; an elastic claw with at least radially-inward one tooth and a radially-outward nub; a connector body attached to the outer contact; and a coupling nut having at least one radially-inward extending nub. The coupling nut is movable between a rear unsecured position, in which the nub of the coupling nut is rearward of the nub of the claw, and a forward secured condition, in which the nub of the coupling nut engages the nub of the claw and forces the at least one tooth of the claw radially inward to engage with a thread of an outer conductor body of a mating female connector. The spring fingers of the spring basket apply radially-outward pressure to the outer conductor body of the mating female connector.

Dependent claims

A quick-locking male connector, comprising:

an inner contact;
an insulator, wherein the inner contact resides within the insulator;
an outer contact, wherein the insulator resides within the outer contact;
a spring basket with a plurality of spring fingers, the spring basket abutting a forward end of the outer contact;
an elastic claw with at least one radially-inward tooth and a radially-outward nub, wherein the spring basket resides within the claw, and wherein a gap exists between the at least one tooth and the spring fingers;
a connector body attached to the outer contact;
and
a coupling nut having at least one radially-inward extending nub;
wherein the coupling nut is movable between a rear unsecured position, in which the nub of the coupling nut is rearward of the nub of the claw, and a forward secured condition, in which the nub of the coupling nut engages the nub of the claw and forces the at least one tooth of the claw radially inward to engage with a thread of an outer conductor body of a mating female connector inserted into the gap between the spring fingers and the tooth of the claw;
and
wherein the spring fingers of the spring basket apply radially-outward pressure to the outer conductor body of the mating female connector,
wherein the spring fingers have no axial contact with the outer conductor body of the mating female connector.
