Abstract
A contact pin includes a pair of plungers capable of being pushed into a socket from respective directions in an upper-lower direction, in which the pair of plungers include plate surface parts, respectively, each plate surface part extending in the upper-lower direction and including an electrode part at one end side, the pair of plungers being disposed such that one electrode part faces upward, other electrode part faces downward, and the plate surface parts face each other, and one plate surface part includes a protrusion on both surfaces of a portion of the one plate surface part which comes to face other plate surface part when both of the pair of plungers are positioned at a push-in position, the protrusion being capable of making point contact or local contact with the other plate surface part.

A contact pin, comprising:
- a pair of plungers capable of being pushed into a socket from respective directions in an upper-lower direction, wherein
- the pair of plungers include plate surface parts, respectively, each of the plate surface parts extending in the upper-lower direction and including an electrode part at one of end sides, the pair of plungers being disposed such that one of the electrode parts faces upward, other one of the electrode parts faces downward, and the plate surface parts face each other, the pair of plungers being configured to be movable in the upper-lower direction between an initial position and a push-in position of each of the pair of plungers, and
- one of the plate surface parts includes a protrusion on both surfaces of a portion of the one plate surface part which comes to face other one of the plate surface parts when both of the pair of plungers are positioned at the push-in position, the protrusion being capable of making point contact or local contact with the other plate surface part.
A plunger forming a contact pin and capable of being pushed into a socket from one direction in an upper-lower direction, wherein:
- the plunger includes a plate surface part extending in the upper-lower direction and including an electrode part at one of end sides, the plunger being configured to be movable in the upper-lower direction between an initial position and a push-in position, the plunger being disposed to be oriented opposite another plunger in the upper-lower direction in a state in which the plate surface part faces a plate surface part of the another plunger, the another plunger forming a pair with the plunger, and
- the plate surface part includes a protrusion on both surfaces of a portion of the plate surface part which comes to face the plate surface part of the another plunger when both of the plunger and the another plunger are positioned at the push-in position, the protrusion being capable of making point contact or local contact with the plate surface part of the another plunger.
