Abstract
Abstract An improved interconnection between a structural member and a shielded coaxial cable reduces the possibility of there being created uneven, failure inducing, tensile stresses. An elongate fitting member is provided with a passageway for electrical or fiber-optic conductors and is sized to be fitted within the coaxially disposed braided shielding. A cylindrically-shaped retaining member is shaped with a bore having dimensions slightly in excess of the combined diameter of the fitting member and thickness of the braided shielding. As the cable is brought under tension, a slight constriction of the braided shielding occurs. This constriction results in a uniform gripping force along the length of the fitting member. A radially extending rim on the innermost extension of the fitting member is brought to bear against the innermost extension of the retaining member and the cable is anchored in place. The coaction of the aforedescribed elements ensures high reliability since there are uniform stresses exerted and no failure-inducing load concentrations.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
245 words
A secure mechanical interconnection comprising: a wall member having an opening therethrough; a coaxial cable having at least one axially extending conductor of electromagnetic energy, insulation covering said conductor, an elongate braided conductive shielding coaxially disposed about said insulation and an elongate flexible covering coaxially carried on said shielding, said cable extending through said opening in said wall member; a rigid elongate tubular-shaped member having an inner diameter sized to contain and containing said conductor therethrough and further having an outer diameter sized to fit and fitting within said braided conductive shielding in a slidable relationship, said elongate tubular-shaped member being provided with an annular rounded shoulder at one end and a radially extending rim at its opposite end and; a rigid cylindrically-shaped member coaxially carried on said rigid elongate tubular-shaped member by having a coaxial bore sized to fit about said tubular-shaped member and said braided conductive shielding, said cylindrically-shaped member being configured with oppositely facing ends for mechanically engaging an inner surface of the wall member and said radially extending rim of said tubular-shaped meMber, as a tensile force is exerted on said coaxial cable, said braided conductive shielding uniformly gripping said elongate tubular-shaped member along the surfaces defined by said outer diameter and said rounded shoulder and said radially extending rim bearing against one oppositely facing end of said rigid cylindricallyshaped member to transfer the tensile force to the wall member via the other oppositely facing end of said rigid cylindrically-shaped member.
Claim 2
Dependent Claim
245 words
A secure mechanical interconnection comprising: a wall member having an opening therethrough; a coaxial cable having at least one axially extending conductor of electromagnetic energy, insulation covering said conductor, an elongate braided conductive shielding coaxially disposed about said insulation and an elongate flexible covering coaxially carried on said shielding, said cable extending through said opening in said wall member; a rigid elongate tubular-shaped member having an inner diameter sized to contain and containing said conductor therethrough and further having an outer diameter sized to fit and fitting within said braided conductive shielding in a slidable relationship, said elongate tubular-shaped member being provided with an annular rounded shoulder at one end and a radially extending rim at its opposite end and; a rigid cylindrically-shaped member coaxially carried on said rigid elongate tubular-shaped member by having a coaxial bore sized to fit about said tubular-shaped member and said braided conductive shielding, said cylindrically-shaped member being configured with oppositely facing ends for mechanically engaging an inner surface of the wall member and said radially extending rim of said tubular-shaped meMber, as a tensile force is exerted on said coaxial cable, said braided conductive shielding uniformly gripping said elongate tubular-shaped member along the surfaces defined by said outer diameter and said rounded shoulder and said radially extending rim bearing against one oppositely facing end of said rigid cylindricallyshaped member to transfer the tensile force to the wall member via the other oppositely facing end of said rigid cylindrically-shaped member.
Claim 3
Dependent Claim
36 words
A secure mechanical interconnection according to claim 1 further including: a gland fitting mounted in said opening of said wall member being sized to receive and receiving said coaxial cable therethrough for ensuring a watertight interconnection.
