Please refer to Figures 1 to 3, the electronic card connector is used to electrically connect the electronic card (not shown) and the printed circuit board (not shown), which mainly includes: an insulating body 1 and a card that matches the insulating body 1 Hold the conductive terminal 2.

The insulating body 1 is a flat rectangular plastic body with an upper surface 11 and a lower surface 12. The upper surface 11 is symmetrical to the lower surface 12 and is provided with a receiving channel 10; the insulating body 1 and the conductive terminal 2 are matched. On the upper surface 11 between the clamping side and the receiving channel 10 , a resisting hole 13 is recessed corresponding to each receiving channel 10 , and the resisting hole 13 is provided through the lower surface 12 . The portion of the lower surface 12 that is engaged with the conductive terminal 2 is recessed toward the upper surface 11 to form a locking groove 14 .

The conductive terminal 2 includes a U-shaped holding portion 20, wherein the holding portion 20 is provided with a first holding plate 201 and a second holding plate 202 in parallel and symmetrically, and a fold elastically connecting the first holding plate 201 and the second holding plate 202. The distance between the bent portion 203 and the parallel first holding plate 201 and the second holding plate 202 is approximately equal to the distance between the upper surface 11 and the lower surface 12 of the insulating body 1 . The free end of the first holding plate 201 is bent and extended at a certain angle with the first holding plate 201 to form the elastic portion 21 , and the free end of the elastic portion 21 extends and bends to form an arc-shaped contact portion 22 .
