Patent ID: 7511519

Claim:
An electric signal connecting device comprising: a probe having a first contact point on one end, a second contact point on another end and a resiliently deformable part in an intermediate portion of the probe, said probe making an electric connection by entering into contact with a terminal for electric connection created in electric functional elements to be tested; and a ribbon-shaped resin film for supporting said probe, the resin film having first and second longitudinally-extending edges spaced in a parallel relation, wherein said probe is formed on or connected to a surface of the resin film so that the resiliently deformable part of the probe is positioned between the first and second longitudinally-extending edges of the resin film and the resiliently deformable part of the probe is in a state resiliently deformable in a first direction, the first direction being perpendicular to the first and second longitudinally-extending edges of the resin film; an opening is formed in a portion of the resin film corresponding to the resiliently deformable part of the probe so that at least a portion of the resin film is in a state resiliently deformable in the first direction; the first contact point of said probe protrudes from the first longitudinally-extending edge of the resin film in a second direction so as to contact with a terminal of the electric functional elements to be tested, the second direction being opposite the first direction and perpendicular to the first and second longitudinally-extending edges of the resin film; the second contact point of said probe is brought into contact in use with the terminal of an electric function testing device; and when a force is applied to the first contact point in the first direction, the resiliently deformable part of the probe resiliently deforms in the first direction, the at least a portion of the resin film resiliently deforms in the first direction, the first contact point moves towards the second longitudinally-extending edge, and signals may be transmitted and received between the electric functional elements to be tested via the first contact point and the electric function testing device via the second contact point.
