Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A shielding assembly for fully enclosing an electrical connector and terminating shielding layers of a fully shielded cable, said shielding assembly comprising: a pair of seamless formed mating metal housing members together defining a full enclosure for an electrical connector, one of said housing members defining an aperture providing access to a mating face of said electrical connector, each said housing member having an integral T-shaped extension with a plurality of flanged apertures formed in a cross bar portion thereof, said apertures being slightly offset with respect to each other in a superimposed condition, whereby crimping end portions of said cross bar upon itself causes said flanged apertures to penetrate a shielding layer from opposite sides forming a sandwich with flanges of one side engaging apertures of the other side and vice versa.
Claim 2
Dependent Claim
133 words
A shielding assembly for fully enclosing an electrical connector and terminating shielding layers of a fully shielded cable, said shielding assembly comprising: a pair of seamless formed mating metal housing members together defining a full enclosure for an electrical connector, one of said housing members defining an aperture providing access to a mating face of said electrical connector, each said housing member having an integral T-shaped extension with a plurality of flanged apertures formed in a cross bar portion thereof, said apertures being slightly offset with respect to each other in a superimposed condition, whereby crimping end portions of said cross bar upon itself causes said flanged apertures to penetrate a shielding layer from opposite sides forming a sandwich with flanges of one side engaging apertures of the other side and vice versa.
Claim 3
Dependent Claim
20 words
A shielding assembly according to claim 1 further comprising: means to hold said housing members together in an assembled condition.
Claim 4
Dependent Claim
23 words
A shielding assembly according to claim 1 further comprising: means to hold said housing members and said connector together in an assembled condition.
Claim 5
Dependent Claim
32 words
A shielding assembly according to claim 1 wherein each said flanged aperture comprises: a plurality of tangs surrounding each respective aperture and extending out of the plane of said cross bar portion.
Claim 6
Dependent Claim
22 words
A shielding assembly according to claim 1 wherein: said housing members mate together with friction fit to form an electrically sealed enclosure.
Claim 7
Independent Claim
98 words
A method of terminating fully shielded cable in which a plurality of conductors arranged in parallel spaced relation are sandwiched between layers of conductive shielding material and enclosed in an insulative sleeve comprising the steps of: removing a portion of said sleeve to expose said shielding layers, peeling back said shielding layers to expose said conductors, terminating said conductors to respective terminals of an electrical connector, terminating each said shielding layer to a respective half of a seamless formed mating metal housing shell member, and fully enclosing said electrical connector in said formed mating metal housing shell members.
Claim 8
Independent Claim
98 words
A method of terminating fully shielded cable in which a plurality of conductors arranged in parallel spaced relation are sandwiched between layers of conductive shielding material and enclosed in an insulative sleeve comprising the steps of: removing a portion of said sleeve to expose said shielding layers, peeling back said shielding layers to expose said conductors, terminating said conductors to respective terminals of an electrical connector, terminating each said shielding layer to a respective half of a seamless formed mating metal housing shell member, and fully enclosing said electrical connector in said formed mating metal housing shell members.
Claim 9
Dependent Claim
81 words
A method according to claim 6 wherein said shielding layers are terminated by the steps of placing each of them on an extension of a respective said one of said metal housing shell members, each said extension having a plurality of flanged apertures therein, and folding said extensions upon themselves so as to sandwich said shielding layer between portions thereof, said aperture flanges penetrating said shielding layer from one side to engage in apertures on the other side and vice versa.
