Abstract
Abstract An electrical connector (10) comprised of intermating halves (12, 80) including snap rings (58, 150), a shroud (50) and sleeve (140) of geometries allowing blind-mating of the connector halves with both halves being readily snapped into block apertures (68, 130) of housings with sufficient axial float to assure proper mating with varying parts tolerances, and with the snap rings not bound by an axial spring element (106) employed to take up such tolerance.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
207 words
A connector of a type having a first connector half retained within an aperture in a housing for mating with a further connector half said connector halbes each having at least one conductive contact therein characterized in that the said first connector half includes resilient means adapted to bias said first half axially in said aperture to accommodate for positional and manufacturing dimensional differences and assure proper mating between the two connector halves and further characterized in that said first connector half includes a tapered snap ring adapted to engage edges of said housing within said aperture to allow said first half to be inserted into said block, the improvement comprising, sleeve means carrying said snap ring therearound with said sleeve means having a flange adapted to engage an edge of said aperture and limit movement of said first half in said housing in one direction, and further having a second flange adapted to engage said resilient means disposed within said aperture operable to bias said first half axially in an composite direction whereby axial forces are precluded from binding said snap ring against radial displacement during insertion of said first half in said housing said racial displacement preventing removal of said first half from said aperture
Claim 2
Dependent Claim
207 words
A connector of a type having a first connector half retained within an aperture in a housing for mating with a further connector half said connector halbes each having at least one conductive contact therein characterized in that the said first connector half includes resilient means adapted to bias said first half axially in said aperture to accommodate for positional and manufacturing dimensional differences and assure proper mating between the two connector halves and further characterized in that said first connector half includes a tapered snap ring adapted to engage edges of said housing within said aperture to allow said first half to be inserted into said block, the improvement comprising, sleeve means carrying said snap ring therearound with said sleeve means having a flange adapted to engage an edge of said aperture and limit movement of said first half in said housing in one direction, and further having a second flange adapted to engage said resilient means disposed within said aperture operable to bias said first half axially in an composite direction whereby axial forces are precluded from binding said snap ring against radial displacement during insertion of said first half in said housing said racial displacement preventing removal of said first half from said aperture
Claim 3
Dependent Claim
34 words
The connector of claim 1 wherein said sleeve means includes a recess dimensioned axially and radially to accommodate said snap ring in radial displacement during insertion of said first connector half within said aperture.
Claim 4
Dependent Claim
176 words
A connector of the type having a first half for mating with a further connector half mounted within an aperture of a housing characterized in that the said further connector half is fixed in said further housing against axial movement during mating with said first connector half, and further characterized in that said further connector half includes a body having an annular groove therein and a tapered snap ring fitted within said groove for radial displacement, said body having a flange adapted to engage an edge surface said aperture to limit axial movement of said further connector half in one direction shroud means fitted over said further connector half body including an outer radial surface adapted to engage an internal radial surface within said aperture to limit movement of said connector body in the other direction and having an interior radial surface adapted to be engaged by said tapered snap ring as said shroud is axially displaced over said body to lock said shroud to said body and to lock said connector half to said housing.
Claim 5
Dependent Claim
176 words
A connector of the type having a first half for mating with a further connector half mounted within an aperture of a housing characterized in that the said further connector half is fixed in said further housing against axial movement during mating with said first connector half, and further characterized in that said further connector half includes a body having an annular groove therein and a tapered snap ring fitted within said groove for radial displacement, said body having a flange adapted to engage an edge surface said aperture to limit axial movement of said further connector half in one direction shroud means fitted over said further connector half body including an outer radial surface adapted to engage an internal radial surface within said aperture to limit movement of said connector body in the other direction and having an interior radial surface adapted to be engaged by said tapered snap ring as said shroud is axially displaced over said body to lock said shroud to said body and to lock said connector half to said housing.
Claim 6
Dependent Claim
41 words
The connector of claim 3 wherein said shroud extends forwardly of said housing in an axial sense beyond said body to serve in aligning the said first half of said connector during mating with the said further half of said connector.
Claim 7
Dependent Claim
179 words
A connector having first and second halves adapted to intermate and interconnect signal paths, housing means for housing said connector halves each having an aperture therein and each aperture including exterior radial edge surfaces and interior radial edge surfaces, each said connector half having a tapered snap ring adapted to be radially displaced about said half, each said connector half having a radial surface adapted to engage the external radial surface of a given housing to limit movement of said half relative to said housing in one direction and each said half having further means including a radial surface interiorly of said aperture adapted to engage said snap rings to preclude movement of said halves relative to said ho in another direction, said second connector half including a resilient spring means to bias said half axially to effect end engagement of the said halves and preclude variations and impedance discontinuities due to tolerances and means on said second half to preclude binding of the said snap rings against radial collapse during insertion of said one half into said housing.
Claim 8
Dependent Claim
179 words
A connector having first and second halves adapted to intermate and interconnect signal paths, housing means for housing said connector halves each having an aperture therein and each aperture including exterior radial edge surfaces and interior radial edge surfaces, each said connector half having a tapered snap ring adapted to be radially displaced about said half, each said connector half having a radial surface adapted to engage the external radial surface of a given housing to limit movement of said half relative to said housing in one direction and each said half having further means including a radial surface interiorly of said aperture adapted to engage said snap rings to preclude movement of said halves relative to said ho in another direction, said second connector half including a resilient spring means to bias said half axially to effect end engagement of the said halves and preclude variations and impedance discontinuities due to tolerances and means on said second half to preclude binding of the said snap rings against radial collapse during insertion of said one half into said housing.
Claim 9
Dependent Claim
54 words
The connector of claim 5 wherein the said first connector half includes a shroud extending axially beyond the end of said first half to engage the aperture of the housing of the said second half prior to the engagement of the said first half with the said second half during mating to effect alignment.
