Document Type and Number:

WIPO Patent Application WO/2010/092682

Kind Code:

A1

Abstract:

A contact device (10) in which damage on fitting surfaces caused by slide of contacts is reduced. The contact device has a conductor (2) and a conductor (1) placed coaxial with the conductor (2) and having a fitting hole (15) into which the conductor (2) can be inserted. The conductors (1, 2) are fitted to each other by axially moving at least either of the conductors (1, 2), thereby electrically connecting the conductors (1, 2) to each other via the contacts. The contact device (10) further has an electrically conductive coiled spring (B1) and an electrically conductive coiled spring (A1). The coiled spring (B1) is circumferentially placed on the outer peripheral surface of the conductor (2) and can make contact with the inner peripheral surface of the fitting hole (15). The coiled spring (A1) is circumferentially placed on the inner peripheral surface of the fitting hole (15) and can make contact with the outer peripheral surface of the conductor (2).
