Abstract
Abstract A one-piece metal shield (12) for a surface mounted connector (10) having a substantially rectangular body (14) from which a plug portion (16) projects forwardly, is in the form of a rectangular box-like structure having a top wall (24) side walls (26) and a front wall (28). The front wall (28) has a circular opening (30) from the edge (32) of which spring fingers (34) project inwardly of the shield (12) for engaging the shielding (19) of a shielded electrical socket inserted through the opening (30) to mate with the plug portion (16). The shield (12) is secured to the body (14) by means of flanges (48 and 50) thereon which engage with a snap action in grooves in the body (14). At least the side walls (26) have mounting legs (54) for securing the shield (12) and thus the body (14) to a substrate. A latching finger (180) shorter than a spring finger (34), projects from edge of opening (30) for latching behind a depressible protuberance (90) on a complementary connector (20). During mating, the protuberance (90) displaces the latching finger (180) which resiles behind protuberance (90) when mating is completed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
A shielded electrical connector (10), having an insulative, substantially rectangular cross-section housing (14) having an annular recess within which projects forward a circular cross-section plug portion (16) for mating with a circular cross-section, externally shielded electrical socket (18), said housing (14) having a top wall (193), side walls and a front wall, a one piece metal shield (12) for shielding portions of said connector housing, said shield (12) having a front wall (28) having a substantially circular through opening (30) therein for receiving said socket (18), said shield (12) characterized by having a top wall (24) for enclosing substantially the entirety of a top wall (193) of said housing (14), a pair of shield side walls (26) each adjacent to the shield top wall (24), for enclosing substantially the entirety of side walls of said housing (14), and a shield front wall (28) adjacent to the shield top wall (24) and the shield side walls (26), whereby shielding is provided over substantially the entire connector housing (14).
Claim 2
Dependent Claim
167 words
A shielded electrical connector (10), having an insulative, substantially rectangular cross-section housing (14) having an annular recess within which projects forward a circular cross-section plug portion (16) for mating with a circular cross-section, externally shielded electrical socket (18), said housing (14) having a top wall (193), side walls and a front wall, a one piece metal shield (12) for shielding portions of said connector housing, said shield (12) having a front wall (28) having a substantially circular through opening (30) therein for receiving said socket (18), said shield (12) characterized by having a top wall (24) for enclosing substantially the entirety of a top wall (193) of said housing (14), a pair of shield side walls (26) each adjacent to the shield top wall (24), for enclosing substantially the entirety of side walls of said housing (14), and a shield front wall (28) adjacent to the shield top wall (24) and the shield side walls (26), whereby shielding is provided over substantially the entire connector housing (14).
Claim 3
Dependent Claim
59 words
A shielded electrical connector (10) as recited in claim 1, wherein said opening (30) defines an edge (32), further characterized by a plurality of resilient, cantilever fingers (34) spaced from each other around said opening (30) and projecting from said edge (32) into said shield (12) for resiliently engaging the external shielding of said socket (18) when received therein.
Claim 4
Dependent Claim
28 words
A shielded electrical connector (10) as recited in claim 1, further characterized by means (44,48,52) on said shield (12) for securing said shield (12) to said housing (14).
Claim 5
Dependent Claim
29 words
A shielded electrical connector (10) as recited in claim 1, further characterized in that said side walls (26) depend from opposite lateral edges (46) of said top wall (24).
Claim 6
Dependent Claim
28 words
A shielded electrical connector (10) as recited in claim 1, further characterized in that said side walls (26) depend from opposite lateral edges of said front wall (28).
Claim 7
Dependent Claim
28 words
A shielded electrical connector (10) as recited in claim 1, further characterized by means (54;54′;54˝;58) depending from said shield (12) for securing said shield to a substrate (S).
Claim 8
Dependent Claim
42 words
A shielded electrical connector (10) as recited in claim 6, wherein said securing means is further characterized by a mounting foot (58) extending from a rudimentary bottom wall of said shield (12), which projects from said shield front wall (28) normally thereof.
Claim 9
Dependent Claim
102 words
A shielded electrical connector (10) as recited in claim 1, further characterized in that the externally shielded electrical socket (18) has a resiliently depressible protrusion (90), one of the fingers (34) being a latching finger (180) that projects inwardly of the circular opening (30) to depress said protrusion (90) as said socket is mated with said shielded electrical connector (10), said latching finger being such that said protrusion (90) resiles when the mating portions of the socket (18) and the shielded electrical connector (10) have been mated to assume a latching position and secure the socket and connector in a mated position.
Claim 10
Dependent Claim
55 words
A shielded electrical connector (10) as recited in claim 8, further characterized in that the latching finger (180) has a free end (184), such that the protrusion (90) resiles behind the free end (184) of latching finger (180) when the socket (18) and shielded electrical connector (10) have been mated to assume a latching position.
Claim 11
Dependent Claim
37 words
A shielded electrical connector (10) as recited in claim 8, further characterized in that the latching finger (180) is connected to the shield (12) by a smoothly arcuate portion (183) for camming engagement with said protrusion (90).
