Abstract

Abstract 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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 197 words
An electrical connector for a coaxial cable (10) terminating at a free end and including a central conductor (12), an insulating layer (16) surrounding the central conductor (12), a braid conductor (14) surrounding the insulating layer (16), and a protective sheath (18) surrounding the braid conductor (14), said electrical connector (100) comprising a terminal body (200), a clamp member (300) disposed within the terminal body (200) and a nut (400) assembling the clamp member (300) to the terminal body (200), said clamp member (300) including a tapered surface (314), and a bore for receiving the central conductor (12) and the insulating layer (16) and extending between a forward face and a rear face, characterized in that the clamp member (300) further includes a spiral groove (316) described by a series of undercuts disposed on the tapered surface (314) such that an edge of each undercut provides a corner surface which engages the braid conductor (14) after the central conductor (12) and the insulating layer (16) are received in the bore and the clamp member (300) is rotated to draw the tapered surface of said clamp member (300) between the insulating layer (16) and the braid conductor (14).
Claim 2
Dependent Claim 197 words
An electrical connector for a coaxial cable (10) terminating at a free end and including a central conductor (12), an insulating layer (16) surrounding the central conductor (12), a braid conductor (14) surrounding the insulating layer (16), and a protective sheath (18) surrounding the braid conductor (14), said electrical connector (100) comprising a terminal body (200), a clamp member (300) disposed within the terminal body (200) and a nut (400) assembling the clamp member (300) to the terminal body (200), said clamp member (300) including a tapered surface (314), and a bore for receiving the central conductor (12) and the insulating layer (16) and extending between a forward face and a rear face, characterized in that the clamp member (300) further includes a spiral groove (316) described by a series of undercuts disposed on the tapered surface (314) such that an edge of each undercut provides a corner surface which engages the braid conductor (14) after the central conductor (12) and the insulating layer (16) are received in the bore and the clamp member (300) is rotated to draw the tapered surface of said clamp member (300) between the insulating layer (16) and the braid conductor (14).
Claim 3
Dependent Claim 37 words
An electrical connector as claimed in claim 1, characterized in that the outer surface of the clamp member (300) is generally frusto-conical in shape with the larger end mounted toward the free end of the cable (10).
Claim 4
Dependent Claim 64 words
An electrical connector as claimed in claim 1 having the nut (400) and the terminal body (200) joined by threads (420,240), characterized in that the rotation of the nut (400) to secure it to the terminal body (200) is in a direction to so urge the series of undercuts as to provide greater engagement of the clamp member (300) and the braid conductor (14).
Claim 5
Dependent Claim 142 words
The method of assembling the electrical connector according to claim 1 with the coaxial cable, characterized by the steps of: cutting the protective sheath, braid conductor and insulating layer of the cable perpendicular to the axis thereof in a substantially uniform length, shorter than the central conductor; slipping the nut over the cable; inserting the central conductor and the insulating layer in the bore of the clamp member and then a portion of the tapered surface of the clamp member between the insulating layer and the braid conductor; rotating the clamp member in the direction of the spiral groove to progressively draw deeper within the braid the clamp member until the entire tapered surface thereof is within the braid; and assembling the nut and the terminal body over the clamp member to complete the electrical contact and captivate the clamp member therebetween.
