The protruding member 111 is installed onto a wall surface inside the insulating body 11 along the card inserting direction 3, and the conducting terminals 114 are installed in the insulating body 11 and are contacted with the electronic card 2. The cover 12 includes a plurality of latch holes 121, and the latch protruding members 113 of the insulating body 11 are latched with the latch holes 121, so that the cover 12 can be covered and fixed to the insulating body 11 to form a slot 16. The sliding portion 13 is disposed at the insulating body 11, and a lateral side of the sliding portion 13 along the card inserting direction 3 is sliding against the protruding member 111, an opposite lateral side has a second positioning rod 132 and a latch arm 131, and a heart-shaped guide groove 134 is disposed between two lateral sides of the sliding portion 13, and the second positioning rod 132 is corresponsive to the first positioning rod 112, and the latch arm 131 and the second positioning rod 132 are disposed back to back with each other, and a pushed portion 133 is disposed between the second positioning rod 132 and the latch arm 131, and a concave opening 1341 of the heart-shaped guide groove 134 faces towards the slot 16. A guide arm 141 is bent separately from both ends of the guide rod 14, and one of the guide arms 141 is pivotally coupled to the insulating body 11, and another guide arm 141 is disposed in the heart-shaped guide groove 134. A first positioning rod 112 and a second positioning rod 132 are disposed at both ends of the resilient element 15 respectively, and the resilient element 15 can be a spring.
Referring to FIGS. 3 to 8 for a perspective view of a sliding portion and schematic views of the operation of an electronic card connector 1 in accordance with the present invention respectively, an upper section on the right side of the sliding portion 13 leans against the protruding member 111, and the resilience of the spring 15 drives a lower section on the right side of the sliding portion 13 to lean against an internal wall surface of the insulating body 11, and drives the latch portion 1311 of the latch arm 131 to the right side, when the electronic card 2 is inserted into the electronic card connector 1 and just contacted with the sliding portion 13. If the electronic card 2 is pushed all the way to the bottom, the pushing portion 21 of the electronic card 2 will push a pushed portion 133 of the sliding portion 13 to compress the spring 15 and store a resilience, and then the right side of the sliding portion 13 will slide on the protruding member 111 to rotate the sliding portion 13 clockwise, and finally the upper section on the right side of the sliding portion 13 is driven to lean against the internal wall surface of the insulating body 11, and the lower section on the right side of the sliding portion 13 is driven to lean against the protruding member 111, and the latch portion 1311 of the latch arm 131 is shifted to the left and into a notch 22 of the electronic card 2. In the meantime, a guide arm (not shown in the figures) of the guide rod 14 is moved along the first blocking edge 1342 towards the right side of the heart-shaped guide groove 134 to the second blocking edge 1343. If the electronic card 2 is released, the spring 15 releases a portion of the resilience to move the sliding portion 13 and the electronic card 2 in a direction opposite to the card inserting direction 3.
