Abstract
Abstract There is disclosed a coaxial cable connector for use with the same nominal size cables of different manufacturers. Although the actual outer diameters of such cables may vary by as much as 10%, the connector includes in the conical bore of a retaining nut a slotted tapered sealing gland whose fingers, when the connector is tightened, are bent inwardly to tightly grip the outer conductor of the cable. The connector also includes a wire mesh ring which, when compressed in the axial direction, expands radially both inwardly and outwardly so as to form a tight mechanical fit and establish good electrical contact and radiation shielding between the outer conductor of the cable and the body of the connector.

Claim 1
Independent Claim
216 words
A coaxial cable connector for attachment to any of several coaxial cables of the same nominal size but whose outer diameters are different comprising a retaining nut having a conical bore therein and an inner diameter large enough to permit placement thereof around even the largest diameter cable to which the connector may be attached, a tapered sealing gland disposed in the conical bore of said retaining nut for placement around the outer conductor of a coaxial cable, the inner diameter of said sealing gland being reduceable as the gland is forced rearward into the conical bore of said retaining nut for securely gripping the outer conductor of said coaxial cable, a wire mesh ring disposed forward of said retaining nut and said sealing gland for placement around the outer conductor of said coaxial cable, a contact pin attachable to the inner conductor of said coaxial cable, and a conducting body portion fittable over said wire mesh ring and attachable to said retaining nut, the movement toward each other of said retaining nut and said body portion causing said wire mesh ring to be axially compressed thereby causing it to expand radially both inwardly and outwardly for establishing a mechanical fit and electrical contact between the outer conductor of said coaxial cable and said body portion.
