CONNECTOR

In the present invention, a cover closes an opening in a housing holding a plurality of terminals. Each of the terminals has a connection part connecting to a mate terminal. The cover has a first surface, a second surface located at a rear side of the first surface including an exposed surface exposed to the inner side of the housing through the opening, a first reinforcement rib projecting from the first surface, and a second reinforcement rib projecting from the second surface. The direction in which the plurality of connection parts are arranged is defined as a first direction. The direction that intersects the first direction and that is oriented from the basal end toward the distal end of the connection parts is defined as a second direction. The first reinforcement rib extends along the first direction. The second reinforcement rib extends along the second direction between adjacent connection parts.
