Patent ID: 7038471

Claim:
A connector for measurement of electric resistance, comprising: an insulating base plate, a plurality of connecting electrode pairs provided on a front surface of the insulating base plate and arranged in accordance with a pattern corresponding to a pattern of a plurality of electrodes on a circuit board to be inspected using an electric resistance measurement, wherein each connecting electrode pair comprises: a core electrode having an end part extending to the front surface of the base plate and an other end part extending to a back surface of the base plate, the core electrode being supported by the insulating plate such that the core electrode can move in a thickness-wise direction with respect to the insulating plate; and a ring-like electrode arranged on the front surface so as to surround the core electrode in a state electrically insulated from the core electrode, and a plurality of relay electrodes provided on a back surface of the insulating base plate, each relay electrode being electrically connected to either one of the core electrode, or ring-like electrode of a respective connecting electrode pair.
