A card connector (100) and a method of manufacturing the card connector are provided. The card connector (100) includes a base (120) including a grounding contact (130); and a shielding tray (110) for holding a card, the shielding tray (110) being operable to form a detachable connection with the base (120), wherein the shielding tray (110) comprises a fixing portion (111) operable to fix the SIM card (200) in position within the shielding tray (110) and mate with the grounding contact (130). The card connector (100) provides a fixing mechanism (111) to both fix the SIM card (200) within the shielding tray (110) and fix the shielding tray (110) to the base (120), with an exposed area of the card minimized so as to improve the shielding performance. The entire shielding tray (110) is automatically grounded upon being fixed to the base (120). A mobile device (1200) utilizing the SIM card connector (100) is also provided.
