The cover member has first and second cover contacting portions. The holddown has a holddown contacting portion extending to face an outer surface of a side wall portion of the insulator.

Abstract: In a connector (1) having a slider (4) movable in a predetermined direction (A1) with respect to a housing (2) to carry a card (11) to a particular position faced to a contact (3), the slider has a pressing part (4a) which is non-flat and elastically deformed to cause restring force while the card is carried towards the particular position. When the card is placed at the particular position, the pressing part presses the card towards the contact by the restoring force. It is preferable that the slider has a butting part (4c) to be brought into contact with a front end of the card and a locking part (4b) to be engaged with a rear end of the card. The pressing part may be formed into a plate-like shape with a protruding part (4e) formed at an intermediate portion in the predetermined direction to protrude towards the card.

Abstract: There is provided a card socket having a simple construction capable of preventing erroneous insertion of a smaller card than a predetermined one. An erroneous card insertion-preventing member has a fixed portion fixed to the housing, an elastic portion coupled to the fixed portion, and a stopper coupled to the elastic portion. The elastic portion is elastically deformed when a predetermined card is inserted so as to be pushed out of a card insertion path, but not elastically deformed when a card having a smaller size than the predetermined one is inserted so as to remain on the path. The predetermined card can be inserted deeply due to the stopper being moved out of the path in accordance with the deformation of the elastic portion, whereas the card having the smaller size is blocked by the stopper.

Abstract: In a connector for a small circuit board, contacting means is formed independently of elastic means that provides contact pressure on the small circuit board when the edge portion of the small circuit board is fitted to the connector. The contacting means comprises for example an insulator film and electrical contacts corresponding to terminals of the plate object. The insulator has first and second surfaces and the electrical contacts are formed on the first surface. The elastic means is for example arranged within a housing of the connector.

Abstract: Sliding contact portions on an inner surface of a bearing seat slidably support a ball head of a ball stud in a housing. Spaces between one or more of the sliding contact portions contain lubricant reserves. Load receiving portions on the outer surface of the bearing seat facing the housing also support the load placed on the ball stud. Protruding portions on the sliding contact portions decrease contact surface area and permit lubricant to cover nearly the entire ball head surface. The load receiving portions and sliding contact portions, including the protruding portions, deform to absorb repeated heavy loads while maintaining friction compensation and stable torque. The ball joint has an improved ability to compensate for dimensional tolerances, which facilitates component manufacture. The load withstanding ability, lubrication efficiency and durability of the ball joint are thus improved.
