Patent ID: 7586316

Claim:
An electrical connecting apparatus comprising: a support member, a flat plate shaped probe board spaced from one surface of said support member, arranged with its one surface opposed to said support member, and provided on its other surface with numerous probes that are connected to a tester and whose tips are capable of abuting on electrode terminals of a device under test for an electrical test by said tester; a fixed portion formed on said one surface of said probe board and provided with a screw hole; a cylindrical spacer capable of positioning said support member at a fixed distance from a top surface of said fixed portion; and a male screw member that is moveable with respect to said cylindrical spacer and that penetrates said support member and said cylindrical spacer and whose tip is capable of being screwed into said screw hole to tighten said support member to said probe board at said distance in accordance with the length of said cylindrical spacer, wherein said probe board has a support plate in which a plurality of conductive paths that penetrate the plate and connect to said tester are formed and a wiring plate in which wiring paths are formed, whose one surface is fixed to said support plate so as to let said wiring paths be connected to corresponding said conductive paths, and on the other surface of which are provided said probes corresponding to said wiring paths, and on said one surface of said support plate is fixed a female screw member to form said fixed portion, and wherein said female screw member is fixed to said support plate at an area of said support plate where no said conductive paths are formed.
