PURPOSE:To provide a connector pin for electrical connection capable of accurately transmitting a signal between an electric circuit on a contact pin side and an electric circuit on a tube side independent of outside vibration or input load CONSTITUTION:A connector pin for electrical connection is expansively, contractively, and slidably fit to a tube 3 so as not to come out, and has a contact pin 2 which is energized in the expansion direction. The contact pin 2 is electrically connected to the tube 3 through the sliding contact part of the outer circumferential surface 2c of a fitting part 2b to the inner circumferential surface 3d of the tube 3 when the contact pin 2 is in a contracting state. A small diameter recess 2d is widely installed except for both ends in the axial direction on the outer circumferential surface 2c of the fitting part 2b of the contact pin 2 so that the outer circumferential surface 2c comes in contact with the inner circumferential surface 3d at only both the ends. Even if the contact varies between line contact and two point contact, the contact area does not vary so widely. |
