Abstract
The invention provides a card connector device capable of stabilizing an open/close operation of an open/close cover for a long time, and of keeping costs down. An engaging axis 13 and an elastic tongue piece 14 are provided at the end of the open/close cover 3, which serves as a base based on which an open/close operation is conducted. The engaging axis 13 turnably and slidably engages a groove 5 that allows free motion by the axis, formed at the rear end of a housing 2. The elastic tongue piece 14 is inserted into the guide groove 7 of the housing 2, and abuts the inner bottom surface of the guide groove 7 during the open/close operation of the open/close cover 3. When the open/close cover 3 is caused to arise relative to the housing 2, and is then rotated forward or backward, the elastic tongue piece 14 runs on curved surfaces 7b and 7d of the guide groove 7, and a reaction force is increased. Thus, it is possible to hold the rise position (half-open state) of the open/close cover 3. However, when the open/close cover 3 is in a close position, since the elastic tongue piece 14 is not required to be flexed, the reaction force is substantially reduced.
