Abstract

Abstract An electrical connecting member is provided with a holding member made of an electric insulating material and a plurality of conductive members held by the holding member in a state of being insulated with each other. One end of each of the conductive members is exposed on one surface of the holding member and the other end of each of the conductive members is exposed on the other surface of the holding member. The conductive members have portions exposed from the holding member, the length of which is longer than the thickness of the holding member. These exposed portions are easily deformed by the pressure force exerted at the time of connecting electric circuit components to reduce the coupling load even when there is irregularity in the heights thereof or unevenness in the junctions of the objects connection, hence enabling high density connections between the electric circuit components. The exposed portions can also be formed to have empty holes 1B, to be porous or, in the alternative, annealed to soften the exposed portions.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 174 words
An electrical connecting member disposable between electrical circuit components for electrically connecting the electrical circuit components, said electrical connecting member comprising: a holding member made of an electric insulating material; and a plurality of conductive members held by said holding member such that each of said conductive members is insulated from each other one of said conductive members, one end of each of said conductive members being exposed on one surface of said holding member and an opposite end of each said conductive members being exposed on another surface of said holding member and each said conductive member having bumps formed on opposite ends thereof, with said bumps being exposed on said holding member and deformable by contact with said elastic circuit components, wherein each said conductive member is provided with empty holes formed only in said bumps, said empty holes being sized for absorbing deformation of said bumps caused by contact with said elastic circuit components, thereby limiting a lateral spread of said conductive member caused by contact with said electrical circuit components.
Claim 2
Dependent Claim 174 words
An electrical connecting member disposable between electrical circuit components for electrically connecting the electrical circuit components, said electrical connecting member comprising: a holding member made of an electric insulating material; and a plurality of conductive members held by said holding member such that each of said conductive members is insulated from each other one of said conductive members, one end of each of said conductive members being exposed on one surface of said holding member and an opposite end of each said conductive members being exposed on another surface of said holding member and each said conductive member having bumps formed on opposite ends thereof, with said bumps being exposed on said holding member and deformable by contact with said elastic circuit components, wherein each said conductive member is provided with empty holes formed only in said bumps, said empty holes being sized for absorbing deformation of said bumps caused by contact with said elastic circuit components, thereby limiting a lateral spread of said conductive member caused by contact with said electrical circuit components.
Claim 3
Dependent Claim 21 words
An electrical connecting member according to claim 1, where said bumps on opposite ends of each said conductive member are malleable.
