Abstract
Abstract A connector includes first and second connector halves 100 and 200 in which contact pins 1 and 4 are respectively held by projections 3a and 6a protruding from insulation plates 3 and 6. The insulation plates are housed within an insulation housing (2, 5) whose internal and external surfaces are coated with a conductive film, so that crosstalk between the neighboring contact pins is prevented, and all elements can be constructed by molding.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A connector comprising a first connector half which holds first contact pins, and a second connector half which holds second contact pins; said first connector half comprising: a first insulation plate including a plurality of parallel projections in which said first contact pins are held, and a first insulation housing including a plurality of holes for receiving said projections, said first insulation housing being coated with a conductive film on internal and external surfaces thereof; and said second connector half comprising: a second insulation plate including a plurality of parallel projections in which said second contact pins are held, and a second insulation housing including a plurality of holes for receiving said projections of said second insulation plate, said second insulation housing being coated with a conductive film on internal and external surfaces thereof; said first and second connector halves being coupled with each other to contact said first contact pins with said second contact pins; wherein said conductive films respectively coated on said first and second insulation housing are each connected to a ground.
Claim 2
Dependent Claim
175 words
A connector comprising a first connector half which holds first contact pins, and a second connector half which holds second contact pins; said first connector half comprising: a first insulation plate including a plurality of parallel projections in which said first contact pins are held, and a first insulation housing including a plurality of holes for receiving said projections, said first insulation housing being coated with a conductive film on internal and external surfaces thereof; and said second connector half comprising: a second insulation plate including a plurality of parallel projections in which said second contact pins are held, and a second insulation housing including a plurality of holes for receiving said projections of said second insulation plate, said second insulation housing being coated with a conductive film on internal and external surfaces thereof; said first and second connector halves being coupled with each other to contact said first contact pins with said second contact pins; wherein said conductive films respectively coated on said first and second insulation housing are each connected to a ground.
Claim 3
Dependent Claim
47 words
