Abstract
Abstract A connector comprises a connector housing (20) formed with a terminal accommodating chamber (21) and a lance (24); and a terminal (30, 40, 50) inserted into the terminal accommodating chamber of the connector housing and engaged with the lance for prevention of removal of the terminal from the connector housing. In particular, knurled portions (26, 37, 47, 55) are formed both in the lance and the terminal, respectively to prevent the terminal inserted into the terminal accommodating chamber from being moved within the connector housing. When the terminal is inserted into the connector housing, as far as the terminal is not e gaged with the lance, the terminal can be moved within the connector housing for positional adjustment between the two. However, after the terminal has been engaged with the lance, the terminal can be fixed to the connector housing firmly by the presence of the knurled portions. Therefore, the terminal can be fixed to the connector housing firmly, without sacrificing the positional adjustment movement of the terminal within the connector housing, thus preventing contact corrosion due to sliding movement between two mated terminals.
