Sheet-like contact device and a connector using this device

A connector device comprising:

• a socket including:
• a socket body with an opening in one side;
• first and second contact members each comprising a TAB tape provided in said socket body so as to face each other, with a plurality of first contact elements patterned on the surfaces of the first and second contact members, the first and second contact members being curved so that said first contact elements have central raised portions, said first and second contact members including slits defined between the first contact elements;
• a flat frame holding said first contact member in its curved state, one side of said first contact member being attached to one side of the frame and an opposite side of the first contact member being attached to another side of the frame;
• said first contact member extending from said one side of the frame to said opposite side of the frame and being free of support by said frame therebetween;
• a plurality of springs each having one end attached to said one side of the frame and an opposite end which is left free, said springs being mounted at the back of said first contact member so as to correspond to and bias said first contact elements;
• said frame being mounted in said socket body in flat, undeformed state,
• a plug including:
• an insert portion that can be inserted in said opening;
• and
• third and fourth contact members each comprising a TAB tape provided on both sides of said insert portion, with second contact elements patterned on the surfaces of the third and fourth contact members, so that said second contact elements can make contact with said first contact elements of the first and second contact members.

A contact device comprising:

• a sheet-like contact member including a plurality of contact elements patterned on its surface and slits defined between the contact elements,
• a frame holding said contact member in a curved state, one side of the contact member being attached to one side of the frame and an opposite side of the contact member being attached to another side of the frame, said contact member extending from said one side of the frame to said opposite side of the frame and being free of support by said frame therebetween;
• and
• a plurality of springs provided on said frame, said frame being supported in flat, undeformed state, said springs being arranged in correspondence with said contact elements and being pressed against the back of said contact member, each of the contact elements being movable separately.

A contact device comprising:

• a socket body with an opening in one side thereof;
• a sheet-like contact member provided in said socket body, and including a plurality of contact elements patterned on the surface of the contact member, the contact member being curved so that said contact elements have raised intermediate portions, said surface including slits defined between the contact elements;
• a flat frame holding said contact member in a curved state, one side of the contact member being attached to one side of the frame and an opposite side of the contact member being attached to another side of the frame, said contact member extending from the sides of the frame across the frame without support by said frame between said sides, said frame being supported in flat undeformed state;
• and
• a plurality of springs each having one end attached to said one side of said frame and an opposite end which is left free, said springs being mounted on the back of said first contact member in correspondence with said first contact elements to bias said first contact elements.

A contact device comprising:

• a socket body with an opening in one side thereof;
• a sheet-like contact member provided in said socket body, and including a plurality of contact elements patterned on the surface of the contact member, the contact member being curved so that said contact elements have raised intermediate portions, said surface including slits defined between the contact elements, to provide a pitch for the contact elements at 0.5 mm or less;
• a flat frame holding said contact member in a curved state, one side of the contact member being attached to one side of the frame and an opposite side of the contact member being attached to another side of the frame, said contact member extending from the sides of the frame across the frame without support by said frame between said sides, said frame being supported in flat undeformed state;
• and
• a plurality of springs each having one end attached to said one side of said frame and an opposite end which is left free, said springs being mounted on the back of said first contact member in correspondence with said first contact elements to bias said first contact elements.

A contact device comprising:

• a socket including;
• a socket body with an opening in one side thereof;
• a sheet-like first contact member provided in said socket, and including a plurality of first contact elements patterned on the surface of the first contact member, said first contact member being bent so that said first contact elements have raised intermediate portions;
• a flat frame holding said first contact member;
• a plurality of springs each having one end attached to said frame and an opposite end which is left free, said springs being mounted at the back of said first contact member in correspondence with said first contact elements to bias said first contact elements;
• and
• a plug including:
• an insert portion that can be inserted in said opening in the socket;
• a sheet-like second contact member provided on said insert portion and including second contact elements patterned on the surface of the second contact member for making contact with said first contact elements;
• a plug body integrally formed with said insert portion;
• a pressure contact plate in said plug body in contact with the back of said second contact member;
• a plurality of projecting pressure contact portions formed on said pressure contact plate, said pressure contact portions corresponding to said second contact elements;
• a cable in which a plurality of leads are arranged in parallel, the cable being in contact with each of said second contact elements;
• a cover attached to said plug body;
• and
• a projecting portion formed on said cover, which clamps said second contact elements and the leads of the cable together with the pressure contact portions of said pressure contact plate.
