A connector includes a terminal, a connector housing to which the terminal is inserted, and a lance provided inside the connector housing. When the terminal is inserted, the lance comes into sliding contact with the terminal, thereby being bent, and a locking portion of the lance returned by elasticity is engaged with an engaging portion of the terminal, whereby the terminal is prevented from falling out toward the rear side. At a lateral side portion of the lance, a protruding piece is provided, and at a side edge in the width direction of a peripheral wall of a box portion of the terminal, a rib is provided. When the terminal is inserted, before the peripheral wall of the box portion comes into sliding contact with the engaging portion of the lance, the rib comes into sliding contact with the protruding piece, thereby bending the lance. |

1. A connector, comprising:
a terminal having a square tubular box portion which is provided at a front end of the terminal and is surrounded by a peripheral wall; and a connector housing to which the terminal is inserted and fixed, wherein a lance is provided inside a terminal accommodating chamber of the connector housing, the lance having a locking portion which is flexible in a direction intersecting with an insertion direction of the terminal to be engaged with an engaging portion provided at the peripheral wall or an extension part of the box portion, and when the terminal is inserted from a rear end of the terminal accommodating chamber, the lance comes into sliding contact with the inserted terminal, thereby being bent, and at a stage where the terminal is inserted up to a predetermined position, the locking portion of the lance returned from a bent state is engaged with the engaging portion of the terminal, whereby the terminal is prevented from falling out toward the rear side, wherein a protruding piece is provided at a lateral side of the lance, and a rib is provided at a side edge in a width direction of the peripheral wall of the box portion of the terminal, and when the terminal is inserted into the terminal accommodating chamber, the rib comes into sliding contact with the protruding piece, thereby bending the lance before the peripheral wall of the box portion comes into the sliding contact with the locking portion of the lance. |
