Electric connector

摘要

An electric connector includes a male connector and a female connector, the male connector including a cylindrical main portion, and a male contact terminal formed at the main portion. The female connector includes a hole into which the main portion is fit, and a female contact terminal formed at the hole for making electrical contact with the male contact terminal when the main portion is fit into the hole. One of the male connector and the female connector includes a guide shaft axially extending in a direction in which the male connector is fit into the female connector, and the other of the male connector and the female connector includes a guide hole for allowing the guide shaft to be inserted thereinto to guide the guide shaft in the direction.
