ABSTRACT:
A connector in which the sliding movement of a movable contact member is stabilized, thereby securing a positive electrical connection. In the connector of the invention, a hollow connection terminal is fitted in a connector housing, and a coil spring and the slidable, movable contact member are received in this connection terminal. When the two connectors are fitted together, the coil spring urges the movable contact member toward a front end of the connector, thereby providing a sufficient contact load. A resilient, electrically-conductive contact band is provided in a gap between an outer peripheral surface of the movable contact member and an inner peripheral surface of the connection terminal. The connection terminal and the movable contact member are electrically connected together through this contact band, and this contact band prevents the movable contact member from being displaced in a direction perpendicular to the direction of fitting of the connection (that is, the axial direction). Therefore, a more stable sliding movement of the movable contact member is achieved, and a positive electrical connection is achieved.
