CONNECTOR

A connector is provided with terminals, stoppers, and a socket insulator. The stoppers are attached to the respective terminals and are housed together with the terminals in the housing parts of the socket insulator. The stoppers are provided with parts to be locked, and lock spring parts that support the parts to be locked. Locking parts and operation parts are formed on the socket insulator. When the stoppers are housed in the housing parts, the locking parts are located rearward of the parts to be locked, and the locking parts restrict rearward movement of the stoppers. The operation parts can be operated in a prescribed direction that intersects the longitudinal direction. When operated, the operation parts cause the parts to be locked to move in the prescribed direction, and the restriction applied by the locking parts to the parts to be locked in released.
