Abstract
Abstract An electrical connector including a pair of interfittable shells 11, 21, an annular shield ring 60 for protecting electrical contacts carried therein from RFI/EMI interference and means for mounting the shield ring to one of the shells, the one shell 21 having a radial flange 22 forwardly of an annular groove 50 sized to receive an annular band 62 of the shield 60. The mounting means are solderless and comprise an annular compression ring 40 sized to circumpose the annular groove 50 and be plastically deformed therein. The annular groove includes a frusto-conical wall 54 which serves to control plastic deformation of compression ring 40 so as to invade the groove 50 to press against shield band 62 and thereby secure the ring therein. Means 63 for resisting rotation of the shield ring are provided.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
An electrical connector comprising a pair of interfittable shells (11, 21), electrical contacts mounted within each shell which engage upon axial slidable mating of said shells along a center axis thereof, means (30, 60) circumposed around the outer surface of said electrical connector for frequency shielding said contacts and means (40) for mounting said shield means to one of said shells, said one shell (21) including a radial flange (22) and an annular groove (50) disposed in the outer surface (25) adjacent thereto, said shield means being of resilient metal and comprising an annular band (32, 62) having one face disposed in abutment against the flange and a portion (34, 64) convexly curved in the longitudinal direction, said mounting means being solderless and characterized by: said annular groove (50) comprising an annular wall (52) and a chamfered wall (54) extending therearound with the chamfered wall defining a frusto-conical surface between the outer surface (25) and the annular wall (52); and an annular compression ring (40) comprised of a conductive material plastically deformed between the chamfered wall (54) and the other face of said annular band (32, 62) of said shield.
Claim 2
Dependent Claim
190 words
An electrical connector comprising a pair of interfittable shells (11, 21), electrical contacts mounted within each shell which engage upon axial slidable mating of said shells along a center axis thereof, means (30, 60) circumposed around the outer surface of said electrical connector for frequency shielding said contacts and means (40) for mounting said shield means to one of said shells, said one shell (21) including a radial flange (22) and an annular groove (50) disposed in the outer surface (25) adjacent thereto, said shield means being of resilient metal and comprising an annular band (32, 62) having one face disposed in abutment against the flange and a portion (34, 64) convexly curved in the longitudinal direction, said mounting means being solderless and characterized by: said annular groove (50) comprising an annular wall (52) and a chamfered wall (54) extending therearound with the chamfered wall defining a frusto-conical surface between the outer surface (25) and the annular wall (52); and an annular compression ring (40) comprised of a conductive material plastically deformed between the chamfered wall (54) and the other face of said annular band (32, 62) of said shield.
Claim 3
Dependent Claim
28 words
The electrical connector as recited in claim 1 further comprising means (28, 38; 80, 63) for preventing rotation of the shield ring (30, 60) relative to the flange.
Claim 4
Dependent Claim
67 words
The electrical connector as recited in claim 2 wherein said rotation preventing means comprises the chamfered wall (54) including a longitudinally extending radial detent (80) and said band (62) including an opening (66) sized to clearance fit about the annular wall, a radial slit (61) and a semi-circular cut-out portion (63), deformed portions of the compression ring (40) invading the radial detent (80) and the cut-out (63).
Claim 5
Dependent Claim
48 words
The electrical connector as recited in claim 2 wherein said rotation preventing means comprises the flange having a slot (28) and said band (32) including a tab (38) extending therefrom and into said slot, deformed portions of compression ring (40) flowing beneath the band and into the slot.
Claim 6
Dependent Claim
118 words
An electrical connector mating portion having a contacting element and an annular electrically conducting shell encircling said element and insulatively spaced therefrom, a continuous annular groove (50) disposed about said shell, a shielding ring (60) having a continuous band (62) coextensive with said groove and convexly curved spring fingers (64) extending forwardly therefrom, and means for mounting said shielding ring relative to said connector mating portion, said mounting means being solderless and characterized by: an annular compression ring (40) having inner and outer circumferential faces (42, 44) and adapted to plastically deform when forced radially inward into said groove; and means (54) coextensive with said groove (50) for deforming the annular compression ring to form a compression fit.
Claim 7
Dependent Claim
118 words
An electrical connector mating portion having a contacting element and an annular electrically conducting shell encircling said element and insulatively spaced therefrom, a continuous annular groove (50) disposed about said shell, a shielding ring (60) having a continuous band (62) coextensive with said groove and convexly curved spring fingers (64) extending forwardly therefrom, and means for mounting said shielding ring relative to said connector mating portion, said mounting means being solderless and characterized by: an annular compression ring (40) having inner and outer circumferential faces (42, 44) and adapted to plastically deform when forced radially inward into said groove; and means (54) coextensive with said groove (50) for deforming the annular compression ring to form a compression fit.
Claim 8
Dependent Claim
60 words
The electrical connector as recited in claim 5 wherein said means for deforming the compression ring include a chamfered wall (54) extending frusto-conically inward from the shell outer surface (25) to an inner annular wall (52) defining the groove, the thickness of said band (62) and said compression ring (40) being less than the width of said annular groove (50).
