HOLDING STRUCTURE OF FLYING CHECKING CONTACTOR, AND FLYING CHECKING DEVICE OF CIRCUIT SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To enable spring portions 22B and 22C to finely exert a function absorbing impact when a contactor 20 contacts with a checking point.SOLUTION: Guide plates 24 and 26 are disposed between the pair of spring portions 22B and 22C, and the guide plates 24 and 26 do not superimpose on the pair of spring portions 22B and 22C in a side view. Therefore, when the contactor 20 moves upward to a middle plate 28 and the guide plates 24 and 26, side surfaces of the guide plates 24 and 26 and the pair of spring portions 22B and 22C do not contact with each other, so that friction is not generated between the guide plates 24 and 26 and the pair of spring portions 22B and 22C, and the pair of spring portions 22B and 22C smoothly and elastically deforms. Consequently, the pair of spring portions 22B and 22C can finely exert the function absorbing impact when the contactor 20 contacts with the checking point.
