Patent ID: 7785113

Claim:
An electrical connection structure for forming an electrical connection between a first connecting member and a second connecting member, the first connecting member comprising a flexible substrate comprising a flexible insulating film, a conductive pad having elasticity and formed on at least one side of the flexible insulating film, a conductive circuit pattern extending from a rim of the conductive pad, and a through-hole formed through a thickness of the flexible insulating film at a planar position within the conductive pad, and a small aperture formed at a planar position within the conductive pad and communicating with the through-hole, said small aperture having a contour located within the contour of the through-hole as viewed in a direction of a thickness of the flexible insulating film, the second connecting member comprising a conductive projection formed on at least one side of the second connecting member and electrically connected with a conductive circuit pattern formed inside or on the second connecting member, wherein the electrical connection is formed in a manner such that the conductive projection of the second connecting member is detachably inserted in the through-hole of the first connecting member, from a side of the flexible insulating film upon which the conductive pad is formed, through the small aperture in the conductive pad, thereby elastically bending the conductive pad and a portion of the flexible insulating film under the conductive pad, along a direction of insertion of the conductive projection, so that the conductive pad is pressed onto the conductive projection due to elastic force of the conductive pad and the flexible insulating film is bent.
