<P>PROBLEM TO BE SOLVED: To secure electroconductive contact between a contact piece, which is not only easy and accordingly inexpensive to manufacture but also easy to maintain, and an electrode, and to provide a checkup jig that supplies electricity to a printed circuit board contributing to improving the electrical performance of contact pieces and a contact piece. <P>SOLUTION: A contact piece 10 comprising an electroconductive contact stylus 11 and a coil spring 12 arranged in series or superposed one over the other is held by a contact piece holder 20 and, being under pressure contact between an electrode 41 connected to a checkup device and a terminal to be checked, comes into electroconductive contact. The coil spring 12 comprises a relay end 122, a spring constant part 123 and an electrode end 121. The electrode end 121 is bent toward the center at the terminal and cut off near the center to come into electroconductive contact with the electrode 41; a checkup jig 1 mounts the contact piece holder 20 holding this contact piece 10 on an electrode unit 40 having the electrode 41 coaxially with the coil spring 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
