PROBE PIN AND ELECTRONIC DEVICE USING THE SAME

摘要

A probe pin has a coil spring having a first end and a second end, a first plunger having a major portion, and a first elastic extension and a second elastic extension that from the major portion in the same direction, and a second plunger forcedly inserted between the first and the second elastic extensions. The first and the second plungers have electric conductivity. The first and the second plungers are inserted from the first and second ends of the coil spring, respectively, so that the first and the second elastic extensions of the first plunger hold the second plunger with the first elastic extension making a forced contact with a surface of the second plunger to form thereat an electric connection between the first and the second plungers.
