Abstract
Abstract A square-shaped body of an insulating material has a plurality of contact housing holes bored therethrough and arranged in a matrix form, and pin contacts are respectively housed in the contact housing holes. Cords of a shielded cable are connected at one end to the rear ends of the pin contacts. A cable clamper is put on and fixed to the shielded cable and the shield of the shielded cable is connected to the inner surface of the cable clamper. The cable clamper is fitted in and fixed to the rear end portion of a tubular shielding member made of metal and the square-shaped body is fitted in and fixed to the front end portion of the shielding member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
231 words
A multipin connector comprising: a square-sectioned body made of an insulating material and having a plurality of contact housing holes bored therethrough in its front-to-back direction and arranged in a matrix form; housing holes pin contacts inserted through the contact of the insulating body, respectively, the front projecting end of each said pin contact forming a contact portion and the rear end portion forming a cord connecting portion; a shielded cable having cords connected to the cord connecting portions of the pin contacts, respectively; a cable clamper made of metal, for fixedly clamping the shielded cable inserted thereinto, said cable clamper being electrically connected with a partly exposed portion of the shield of said shielded cable; a tubular shielding member made of metal, the rear portion of said tubular shielding member having fitted therein the cable clamper and the forward portion of said tubular shielding member having said insulating body fitted therein and fixed thereto so that said tubular shielding member substantially completely surrounds said pin contacts; locking means including a spring piece disposed on the outer circumference of said shielding member, said spring piece having a radially outward protrusion on its front end portion for locking engagement with a mating connector that is to be connected therewith; and a cover mounted around said shielding member, said cover being arranged to leave the front end portion of said shielding member exposed.
Claim 2
Dependent Claim
231 words
A multipin connector comprising: a square-sectioned body made of an insulating material and having a plurality of contact housing holes bored therethrough in its front-to-back direction and arranged in a matrix form; housing holes pin contacts inserted through the contact of the insulating body, respectively, the front projecting end of each said pin contact forming a contact portion and the rear end portion forming a cord connecting portion; a shielded cable having cords connected to the cord connecting portions of the pin contacts, respectively; a cable clamper made of metal, for fixedly clamping the shielded cable inserted thereinto, said cable clamper being electrically connected with a partly exposed portion of the shield of said shielded cable; a tubular shielding member made of metal, the rear portion of said tubular shielding member having fitted therein the cable clamper and the forward portion of said tubular shielding member having said insulating body fitted therein and fixed thereto so that said tubular shielding member substantially completely surrounds said pin contacts; locking means including a spring piece disposed on the outer circumference of said shielding member, said spring piece having a radially outward protrusion on its front end portion for locking engagement with a mating connector that is to be connected therewith; and a cover mounted around said shielding member, said cover being arranged to leave the front end portion of said shielding member exposed.
Claim 3
Dependent Claim
92 words
The multipin connector of claim 1 wherein said locking means further comprises a sliding piece disposed between said spring piece and the outer circumference of said shielding member in a manner to be slidable back and forth, and coiled spring means mounted around said shielding member for forwardly biasing said sliding piece, said cover being movable back and forth and being rearwardly engageable with the rear end portion of said sliding piece whereby said cover is forwardly biased by said coiled spring means via the rear end portion of said sliding piece.
Claim 4
Dependent Claim
128 words
The multipin connector according to claim 2 further including a mating connector comprising: a square body of an insulating material having a plurality of socket contact holes therein arranged in a matrix form; a plurality of socket contacts housed in said socket contact holes, respectively, for engagement with said pin contacts; a square shielding member mounted around said square body, said square shielding member having a protrusion; a piece covering said square shielding member, said case having a recess formed at the front end portion thereof for receiving said sliding piece and said spring piece, and an engaging hole formed in the ceiling of said recess in opposing relation to the said protrusion of said square shielding member for receiving said radially outward protrusion of said spring piece.
Claim 5
Dependent Claim
48 words
The multipin connector of claim 2 wherein a holding portion is fixedly mounted around the rear end portion of said shielding member and said cable clamper, and said cover is forwardly engageable with said holding portion so that the cover may not slip away from the shielding member.
Claim 6
Dependent Claim
33 words
The multipin connector of claim 4, wherein the coiled spring is wound around the shielding member, the rear end of the coiled spring being engaged with the front end of the holding portion.
Claim 7
Dependent Claim
49 words
The multipin connector of claim 4 wherein said coiled spring means comprises a plurality of small-diametered coiled springs disposed around said shielding member along different parallel axes, the rear end of each coiled spring being engaged with a stepped portion of said shielding member to bias said cover forward.
