Abstract The invention relates to a connector for the chip card of an electronic device, such as a SIM (Subscriber Identity Module) card used to identify the user of a mobile station or the subscriber of a network service. The electrical contact between the connector and the chip card is provided by metal balls (3A) fastened to the flexible parts (4A) of the connecting springs. The ball (3A) is welded on the ball bed formed on the spring (4A) and it is supported by the edge of the opening (3B) in the frame. Due to the support provided by the ball (3A) and the edge (3B), the chip card can be slipped to the connector from several directions.
