Abstract:
1. An electrical connecting apparatus for connecting a tester and electrical connection terminals of a device to undergo an electrical test by the tester, comprising: a supporting member having a mounting reference plane; a wiring base plate in which a wiring circuit to be connected with the tester and disposed such that one face opposes said reference plane of said supporting member, while the other face has a plurality of connection terminals of said wiring circuit; a probe assembly having a plate-like probe base plate with bending deformation produced in a free state without load and a plurality of probes which are provided on one face of said probe base plate and whose tips are capable of abutting the connections terminals of the device under test, and the other face of said probe base plate is disposed to oppose the other face of said wiring base plate; electrical connectors disposed between said probe base plate and said wiring base plate to connect the connection terminals of said wiring base plate with the probes corresponding to said connection terminals; and a plurality of spacers disposed between the other face of said probe base plate and the reference plane of said supporting member so as to maintain the deformation of said probe base plate; wherein said probe tips are positioned on the same plane with the deformation of said probe base plate maintained.
