A frame () is formed with a slider accommodating space () and a housing accommodating space () that are partitioned by inner walls (). A slider () is formed with cam grooves () to face the housing accommodating space (), and a male housing () is pulled to a connection position by a movement of the slider () in a direction substantially normal to a connecting direction with cam pins () of the male housing () engaged with the cam grooves (). The inner walls () have thinned portions () reducing the thickness of the inner walls (). Surrounding walls () of receptacles () of auxiliary housings () enter the thinned portions () to arrange the surrounding walls () in proximity to main portions () of the slider ().

Connector with movable member for assisting connection with a mating connector

A terminal fitting (A) has a receiving portion () with a contact surface () for contacting a male tab (T). The contact surface () is widest at the front end and substantially narrowed toward the back. A rate at which a contact area of the male tab (T) and the contact surface () increases in the insertion process of the male tab (T) is smaller as compared to a substantially rectangular contact surface having a constant width. The terminal fitting (A) provides good operation feeling upon manually connecting the male tab (T) with the terminal fitting (A).
