Abstract
Abstract A multiple pole electrical connector includes a cylindrical metal shell (6); and insulation housing (7) placed within the metal shell and having a plurality of ground member recesses (20) formed on its circumferential surface; a plurality of detachable terminals (8) supported by the insulation housing, one of the detachable terminals serving as a ground terminal (9); and a detachable ground member (23) mounted on the ground terminal with a shell contact portion (24) thereof fitted in the ground member recess such that when the insulation housing is placed within the metal shell, the shell contact portion comes into close contact with an inside of the metal shell.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
146 words
A multiple pole electrical connector comprising: a cylindrical metal shell; an insulation housing placed within said metal shell and having a plurality of ground member recesses formed on its circumferential surface a plurality of terminal apertures; and a plurality of channels formed on a rear end surface thereof to connect said ground member recesses and said terminal apertures; a plurality of detachable terminals having an enlarged intermediate portion inserted into said terminal apertures of said insulation housing, one of said detachable terminals serving as ground terminal; and a detachable ground member mounted on said ground terminal with a shell contact portion thereof fitted in said ground member recess and a linkage portion thereof fitted in one of said channels such that when said insulation housing is placed within said metal shell, said shell contact portion comes into close contact with an inside of said metal shell.
Claim 2
Dependent Claim
146 words
A multiple pole electrical connector comprising: a cylindrical metal shell; an insulation housing placed within said metal shell and having a plurality of ground member recesses formed on its circumferential surface a plurality of terminal apertures; and a plurality of channels formed on a rear end surface thereof to connect said ground member recesses and said terminal apertures; a plurality of detachable terminals having an enlarged intermediate portion inserted into said terminal apertures of said insulation housing, one of said detachable terminals serving as ground terminal; and a detachable ground member mounted on said ground terminal with a shell contact portion thereof fitted in said ground member recess and a linkage portion thereof fitted in one of said channels such that when said insulation housing is placed within said metal shell, said shell contact portion comes into close contact with an inside of said metal shell.
Claim 3
Dependent Claim
18 words
The multiple pole electrical connector of claim 1, wherein said shell contact portion has a curved comb-like shape.
Claim 4
Dependent Claim
27 words
The multiple pole electrical connector of claim 1, wherein said terminal apertures have an enlarged rear portion for receiving said enlarged intermediate portion of a detachable terminal.
Claim 5
Dependent Claim
33 words
The multiple pole electrical connector of claim 1, wherein said ground member further comprises a ring-shaped attachment portion to be fitted over a stepped down ground member attachment portion of said ground terminal.
Claim 6
Dependent Claim
193 words
A multiple pole electrical connector comprising: a cylindrical metal shell; a cylindrical dielectric housing placed within said metal shell and having a plurality of terminal apertures extending therethrough and having an enlarged intermediate portion, a plurality of ground member mounting recesses formed on a circumferential surface thereof, and a plurality of linkage channels formed on said rear end surface thereof to connect said terminal apertures to said mounting recesses; a plurality of signal terminals each having a first enlarged intermediate portion fitted in one of said enlarged rear portions of said terminal apertures; a ground terminal having a second enlarged intermediate portion which has a diameter substantially equal to that of said first enlarged intermediate portion, except a stepped down rear portion, so that said ground terminal is able to be inserted any of said terminal apertures; and a ground member having a ring-like portion to be fitted over said stepped down rear portion of said ground terminal, a comb-like contact portion to be mounted in one of said mounting recesses, and a linkage portion fitted in one of said linkage channels and connecting said comb-like contact portion to said ring-like attachment portion.
Claim 7
Dependent Claim
193 words
A multiple pole electrical connector comprising: a cylindrical metal shell; a cylindrical dielectric housing placed within said metal shell and having a plurality of terminal apertures extending therethrough and having an enlarged intermediate portion, a plurality of ground member mounting recesses formed on a circumferential surface thereof, and a plurality of linkage channels formed on said rear end surface thereof to connect said terminal apertures to said mounting recesses; a plurality of signal terminals each having a first enlarged intermediate portion fitted in one of said enlarged rear portions of said terminal apertures; a ground terminal having a second enlarged intermediate portion which has a diameter substantially equal to that of said first enlarged intermediate portion, except a stepped down rear portion, so that said ground terminal is able to be inserted any of said terminal apertures; and a ground member having a ring-like portion to be fitted over said stepped down rear portion of said ground terminal, a comb-like contact portion to be mounted in one of said mounting recesses, and a linkage portion fitted in one of said linkage channels and connecting said comb-like contact portion to said ring-like attachment portion.
