Abstract

A shield connector wherein maintenance thereof such as replacement of terminals can be performed readily and admission of water is prevented. The shield connector comprises a tubular outer housing made of an insulating resin material, a tubular metal shell inserted in the outer housing and having a semi-annular contacting portion formed thereon, an inner housing made of an insulating resin material and inserted in the metal shell, a plurality of terminals removably accommodated in the inner housing and connected to a shield cable, a rear shell removably fitted in the metal shell and having a semi-annular contacting portion formed thereon, an annular cap made of an insulating resin material for removably holding therein the semi-annular contacting portions of the metal shell and the rear shell with a shield portion of the shield cable inserted between the semi-annular contacting portions, and a rear cover made of a synthetic resin material and removably fitted with a rear end portion of the outer housing. The shield cable extends through the rear cover.

Claims

1. A demountable shield connector, comprising:

a tubular outer housing made of an insulating resin material;

a tubular metal shell inserted in and retained on said outer housing and having a semi-annular contacting portion formed at a rear portion thereof;

an inner housing made of an insulating resin material and inserted in and retained on said metal shell;

a shield cable;

a plurality of terminals removably accommodated in said inner housing and connected to said shield cable;

a rear shell fitted in and removably retained at a rear portion of said metal shell in such a manner as to close a rear end opening of said metal shell and having a semi-annular contacting portion formed at a rear portion thereof for cooperating with said semi-annular contacting portion of said metal shell;

an annular cap made of an insulating resin material for removably holding therein said semi-annular contacting portions of said metal shell and said rear shell in an opposing relationship with each other with a shield portion of said shield cable inserted between said semi-annular contacting portions; and

a rear cover made of a synthetic resin material and fitted with and removably retained at a rear end portion of said outer housing, said shield cable extending through said rear cover.

2. A demountable shield connector as claimed in claim 1, wherein a waterproof seal rubber member is provided integrally at each of a portion of said rear cover from which said shield cable extends outwardly and another portion of said rear cover at which said rear cover is fitted with said metal shell, and a seal rubber member is fitted at a front end portion of said outer housing for contacting with the outer housing of a companion shield connector adapted to cooperate with said shield connector to make up a shield connector assembly.

3. A demountable shield connector as claimed in claim 1, wherein said annular cap has an inner circumferential face the diameter of which increases away from said metal shell so as to facilitate insertion of said semi-annular contacting portions of said metal shell and said rear shell into said annular cap.

4. A demountable shield connector as claimed in claim 1, further comprising a holder removably retained on said inner housing and holding said terminals thereon.
