Abstract

The position where the pointed part of a moving-side terminal comes into sliding contact with an insert is substantially identical to the position where the pointed part of the moving-side terminal touches the upper surface of a terminal plate in a connector. As a result, cutting chips produced through the contact of the insert and the pointed part or foreign matters adhering to the insert adhere to the pointed part of the moving-side terminal and are caught between the pointed part and the terminal plate. Therefore, electrical disconnection may occur when the insert is inserted into the connector. A connector of this invention comprises a switch section composed of the moving-side terminal (51) moved when an insert (53) is inserted into the connector body and a receiving-side terminal (52) so arranged as to come into contact with the moving-side terminal. A pointed part (51a) is provided to the moving-side terminal, and the receiving-side terminal touches the side of the pointed part, thus establishing electrical connection.
