CONNECTOR

PROBLEM TO BE SOLVED: To downsize a connector. SOLUTION: A bolt 15 is installed at a female side housing 10 (connector housing of one side), and a nut 35 is installed at a male side housing 30 (connector housing of the other side), and both housings 10, 30 are made to fit by screwed engagement of the bolt 15 and the nut 35. The bolt 15 and the nut 35 are composed of an electron-conductive material, and an electric wire 22 (conductive path) and a terminal parts 45, 46 (conductive path) are connected to the bolt 15 and the nut 35, and the wire 22 and the terminal part 45, 46 become possible to be conductive to each other via the bolt 15 and the nut 35. Since the bolt 15 and the nut 35 as a mating means have been used in common as the electro-conductive path, the number of poles of connector can be reduced and the connector can be downsized.
