Abstract
Abstract A three-piece self-retaining conduit anchoring device is disclosed for connecting a co-axial cable assembly with a support structure, including an inner sleeve member, an outer sleeve member concentrically arranged about the inner sleeve member, and a collar member concentrically arranged about the outer sleeve member. One end of the collar member abuts one side of the support, the other end of the collar member being supported against axial displacement by flange portions at the corresponding ends of the inner and outer sleeve members. The outer sleeve member includes a plurality of circumferentially arranged external resilient prongs that engage the other side of the support, which outer sleeve member is connected against axial displacement relative to the inner sleeve and collar members. Consequently, the collar flange and the outer sleeve prongs grip opposite surfaces of the support structure to rigidly connect the anchoring device thereto. Internal and external seal members may be provided for preventing the introduction of moisture and foreign matter into the cable assembly.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
333 words
A self-retaining anchoring assembly for mounting a coaxial cable within a through bore defined in a support member, said coaxial cable including concentrically arranged inner and outer members, comprising (a) an inner sleeve member having at one end radially outwardly extending first abutment means, said inner sleeve member including adjacent its other end internal stop means arranged for engagement by the extremity of the outer cable member when said cable member is introduced axially into said inner sleeve member from said one end thereof with the inner cable member projecting from the other end thereof; (b) an outer sleeve member mounted concentrically about said inner sleeve member, said outer sleeve member being in abutting engagement at one end with said inner sleeve first abutment means, said outer sleeve member including adjacent said one end radially outwardly extending second abutment means; and (c) an annular collar member arranged concentrically about said outer sleeve member and in abutting engagement at one end with said outer sleeve second abutment means; (d) said outer sleeve member including adjacent its other end a plurality of integral, circumferentially spaced external resiliently outwardly biased prong portions that extend at one end in the direction of the said outer sleeve member one end, the extremities of said prongs being spaced from the other end of said collar member a distance equal to the thickness of said support member, whereby when the end of the anchoring assembly adjacent the said other end of said outer sleeve member is progressively introduced within the support bore to a position in which the other end of said collar member is in engagement with one face of the support member, the extremities of the prong members, following inward compression during insertion of the outer sleeve member within the support bore, are resiliently expanded outwardly to positions in which the prong extremities are in engagement with the opposite face of the support member, thereby to prevent axial displacement of the anchoring assembly relative to the support member.
Claim 2
Dependent Claim
333 words
A self-retaining anchoring assembly for mounting a coaxial cable within a through bore defined in a support member, said coaxial cable including concentrically arranged inner and outer members, comprising (a) an inner sleeve member having at one end radially outwardly extending first abutment means, said inner sleeve member including adjacent its other end internal stop means arranged for engagement by the extremity of the outer cable member when said cable member is introduced axially into said inner sleeve member from said one end thereof with the inner cable member projecting from the other end thereof; (b) an outer sleeve member mounted concentrically about said inner sleeve member, said outer sleeve member being in abutting engagement at one end with said inner sleeve first abutment means, said outer sleeve member including adjacent said one end radially outwardly extending second abutment means; and (c) an annular collar member arranged concentrically about said outer sleeve member and in abutting engagement at one end with said outer sleeve second abutment means; (d) said outer sleeve member including adjacent its other end a plurality of integral, circumferentially spaced external resiliently outwardly biased prong portions that extend at one end in the direction of the said outer sleeve member one end, the extremities of said prongs being spaced from the other end of said collar member a distance equal to the thickness of said support member, whereby when the end of the anchoring assembly adjacent the said other end of said outer sleeve member is progressively introduced within the support bore to a position in which the other end of said collar member is in engagement with one face of the support member, the extremities of the prong members, following inward compression during insertion of the outer sleeve member within the support bore, are resiliently expanded outwardly to positions in which the prong extremities are in engagement with the opposite face of the support member, thereby to prevent axial displacement of the anchoring assembly relative to the support member.
Claim 3
Dependent Claim
37 words
Apparatus as defined in claim 1, wherein said stop means comprises a transverse wall adjacent the said other end of said inner sleeve member, said transverse wall containing a central bore for receiving the inner cable member.
Claim 4
Dependent Claim
41 words
Apparatus as defined in claim 2, wherein the length of said outer sleeve member is greater than that of said inner sleeve member, thereby to define a space between said other end of said outer sleeve member and said transverse wall.
Claim 5
Dependent Claim
34 words
Apparatus as defined in claim 1, wherein said inner sleeve member includes adjacent its said other end a tubular portion of reduced inner diameter having an annular shoulder that defines said internal stop means.
Claim 6
Dependent Claim
29 words
Apparatus as defined in claim 4, wherein said inner sleeve member includes at said other end a transverse wall containing a through bore for receiving the inner cable member.
Claim 7
Dependent Claim
48 words
Apparatus as defined in claim 5, and further including an annular resilient seal mounted within the tubular portion of reduced diameter of said inner sleeve member, said seal being in engagement at one end with said transverse wall and terminating at its other end adjacent said annular shoulder.
Claim 8
Dependent Claim
23 words
Apparatus as defined in claim 6, wherein the internal diameter of said annular seal corresponds with the diameter of the inner cable member.
Claim 9
Dependent Claim
80 words
Apparatus as defined in claim 4, wherein the length of said inner sleeve member is greater than that of said outer sleeve member, said portion of reduced internal diameter of said inner sleeve member being arranged externally of said outer sleeve member and being spaced from the other end of said inner sleeve member, and further wherein said inner sleeve member includes at its said other end a transverse wall containing a through bore for receiving the inner cable member.
Claim 10
Dependent Claim
54 words
Apparatus as defined in claim 8, and further including an annular resilient seal member mounted at one end concentrically about the said other end of said inner sleeve member, said seal member having at its other end a reduced portion the internal diameter of which corresponds generally with that of the cable inner member.
Claim 11
Dependent Claim
20 words
Apparatus as defined in claim 1, wherein said collar member includes at its other end an annular external flange portion.
Claim 12
Dependent Claim
37 words
Apparatus as defined in claim 10, and further including an annular resilient seal member mounted concentrically upon said collar flange portion and adapted to extend between said collar member and the adjacent face of the support member.
Claim 13
Dependent Claim
36 words
Apparatus as defined in claim 4, wherein said other end of said outer sleeve member is also reduced in internal diameter to correspond with the reduced diameter of said other end of said inner sleeve member.
Claim 14
Dependent Claim
67 words
Apparatus as defined in claim 12, wherein the said other end of said inner sleeve member is stepped to define a further portion of reduced internal diameter, said further reduced portion terminating in a transverse wall containing a through bore for receiving the inner cable member, and further including an annular resilient seal member arranged concentrically within both of said inner sleeve portions of reduced inner diameter.
