Abstract:
1. A card connector adapted for receiving a SIM card and a micro SIM card therein, comprising: an insulating housing of a substantially rectangular board shape with a receiving chamber opened along a front-to-rear direction in a top thereof and penetrating through a front side of the insulating housing, a pair of side walls forming at two opposite sides of the receiving chamber, a fool-proofing board being movably located in the receiving chamber and a substantial middle of a front thereof being concaved rearward to form an inserting chamber, a pair of receiving fillisters being opened in two face-to-face inner sides of the side walls to connect with the receiving chamber and each extending along the front-to-rear direction in front of the fool-proofing board, a bottom side of the receiving chamber defining a plurality of terminal cavities; a plurality of electrical terminals assembled in the terminal cavities of the insulating housing respectively and elastically stretching upward into the receiving chamber and the inserting chamber; two restraining members of which each has a base strip disposed in a front of the corresponding receiving fillister of the insulating housing, and an elastic arm extending rearward from a rear end of the base strip and inclined inward to stretch into the receiving chamber; and a shielding shell enclosing the insulating housing together with the electrical terminals and the restraining members, wherein the elastic arms of the restraining members are pressed into the corresponding receiving fillisters when the SIM card is inserted in the receiving chamber to electrically contact with the electrical terminals, in the process of inserting the micro SIM card into the card connector, the elastic arms of the restraining members elastically resist against two opposite side edges of the micro SIM card so as to guide a rear of the micro SIM card to be smoothly inserted into the inserting chamber and further realize an electrical connection between the micro SIM card and the electrical terminals.
