(57) Electrical connector for a coaxial cable (10) of the type having a central conductor
(12) separated from a braid conductor (14) by an insulation layer (16), and with a
jacket (18) around the braid conductor (14), said connector (100) comprising a rear
nut (400), a forward body (200), and a medial clamp member (300), the clamp member
(300) having a central aperture extending therethrough from front to rear for receiving
the insulation layer (16) and central conductor (14) therein, a frusto-conical portion
of a smaller diameter at the rear of the clamp member, and a helical groove which
is machined into the frusto-conical portion to provide a series of undercuts, and
said connector (100) being assembled over the coaxial cable (10) with the nut (400)
slipped over the cable (10), the clamp member (300) inserted between the braid conductor
(14) and the insulation layer (16) and then rotated in the direction of the helical
groove to progressively draw the clamp member (300) within the braid conductor (14)
until the entire frusto-conical portion is within the braid conductor (14), such that
an edge of each undercut provides a comer surface which engages the braid conductor
(14), securing it and providing a resistance to undesirable axial movement of the
clamp member (300) away from the cable (10), and with the nut (400) secured to the
body (200) by means of interfitting threads (420, 240) to complete the electrical
contact and captivate the clamp member (300) therebetween in proper position.
