Abstract
Abstract An electrical connector includes an insulating housing having an annular recess extending rearwardly from a front end thereof and a shield member having a cylindrical wall fitted into the annular recess, a plurality of contact lugs extending outwardly in radial directions from a front edge thereof, and a leg member for connection with a shield circuit of a printed circuit board. The shield member has a plurality of first cantilever contacts bent outwardly and then inwardly forming an outward projection for contact with a metal shield provided on an inside of a mating shell member and a plurality of second cantilever contacts bent inwardly and then outwardly forming an inward projection for contact with a metal shield provided on an outside of the mating shell member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
An electrical connector comprising: an insulating housing having an annular recess extending rearwardly from a front end thereof; and a shield member having a cylindrical wall fitted into said annular recess, a plurality of contact lugs extending outwardly in radial directions from a front edge thereof, and a leg member for connection with a shield circuit of a printed circuit board; said shield member having a plurality of first cantilever contacts bent outwardly and then inwardly forming an outward projection for contact with a metal shield provided on an inside of a mating shell member and a plurality of second cantilever contacts bent inwardly and then outwardly forming an inward projection for contact with a metal shield provided on an outside of said mating shell member.
Claim 2
Dependent Claim
126 words
An electrical connector comprising: an insulating housing having an annular recess extending rearwardly from a front end thereof; and a shield member having a cylindrical wall fitted into said annular recess, a plurality of contact lugs extending outwardly in radial directions from a front edge thereof, and a leg member for connection with a shield circuit of a printed circuit board; said shield member having a plurality of first cantilever contacts bent outwardly and then inwardly forming an outward projection for contact with a metal shield provided on an inside of a mating shell member and a plurality of second cantilever contacts bent inwardly and then outwardly forming an inward projection for contact with a metal shield provided on an outside of said mating shell member.
Claim 3
Dependent Claim
70 words
The electrical connector of claim 1, which further comprises an end face protection member which is made from a metal sheet thicker than that of said sheld member to cover said front end of said insulating housing coming into contact with said contact lugs to shield front and side portions of said electrical connector and has a central opening for guiding said mating shell member upon plugging in or out.
Claim 4
Dependent Claim
47 words
The electrical connector of claim 2, wherein said end face protection member has a plurality of latch lances for engagement with latch slots provided on a front portion of said insulating housing to make said end face protection member detachable by means of a simple extracting tool.
Claim 5
Dependent Claim
137 words
An electrical connector comprising: an insulating housing having an annular recess extending rearwardly from a front end thereof and a U-shaped recess extending forwardly from a rear end thereof; a U-shaped hood member which is inserted into said U-shaped recess and has a plurality of attaching members with a free contact end and a plurality of first cantilever contacts for contact with a metal shield provided on an inside of a mating shell member; and a shield member having a cylindrical wall fitted into said annular recess and a plurality of contact lugs extending outwardly in radial directions from a front edge thereof, said shield member having a plurality of second cantilever contacts bent inwardly and then outwardly forming an inward projection for contact with a metal shield provided on an outside of said mating shell member.
Claim 6
Dependent Claim
137 words
An electrical connector comprising: an insulating housing having an annular recess extending rearwardly from a front end thereof and a U-shaped recess extending forwardly from a rear end thereof; a U-shaped hood member which is inserted into said U-shaped recess and has a plurality of attaching members with a free contact end and a plurality of first cantilever contacts for contact with a metal shield provided on an inside of a mating shell member; and a shield member having a cylindrical wall fitted into said annular recess and a plurality of contact lugs extending outwardly in radial directions from a front edge thereof, said shield member having a plurality of second cantilever contacts bent inwardly and then outwardly forming an inward projection for contact with a metal shield provided on an outside of said mating shell member.
Claim 7
Dependent Claim
42 words
The electrical connector of claim 4, which further comprises an end face protection member to cover a front end of said insulating housing coming into contact with said contact lugs thereby shielding part of front and side portions of said electrical connector.
Claim 8
Dependent Claim
54 words
The electrical connector of claim 5, wherein said end face protection member has a plurality of first latch lances for engagement with a plurality of latch slots on a front end of said insulating housing and a plurality of second latch lances each having a contact member for contact with said free contact end.
