Patent ID: 7525329

Claim:
An electrical connecting apparatus comprising: a circuit board inside of which wiring paths are provided, on one surface of which a reinforcing plate is provided, and at an outer edge portion of which connectors for removably connecting electrical wires from testers to the corresponding wiring paths are provided, the outer edge portion being exposed from said reinforcing plate; an electric coupler arranged on the other surface of said circuit board; a probe board disposed with its one surface opposed to said electric coupler and provided with wiring paths corresponding to the wiring paths of said circuit board; and a plurality of probes provided on the other surface of said probe board; wherein each wiring path of said circuit board has: a first vertical path portion penetrating said circuit board at the outer edge portion in its thickness direction and connected to said connector on the one surface of said circuit board; a second vertical portion penetrating said circuit board in its thickness direction and connected to said electric coupler on the other surface of said circuit board; and a lateral path portion connecting both said vertical path portions; wherein each wiring path of said probe board is connected to the corresponding second vertical path portion of said wiring path of said circuit board through said electric coupler at one connecting end portion provided on the one surface of said probe board and connected to the corresponding probe at the other connecting end portion provided on the other surface of said probe board; wherein said second vertical path portion exists within an area corresponding to an arrangement area of said reinforcing plate, and an arrangement area of the other connecting end portion of the wiring path of said probe board is wider than that of said one connecting end portion of said wiring path of said probe board; wherein the planar shape of said probe board is larger than that of said reinforcing plate, the arrangement area of said probe board sticking outward over the arrangement area of said reinforcing plate; and wherein the arrangement area of the one connecting end portion of the wiring path of said probe board is within the arrangement area corresponding to the arrangement area of said reinforcing plate.
