Hereinafter, a specific embodiment of the electronic card connector assembly of the present invention will be described with reference to the first to sixth figures. The definition is the front end before the card insertion direction, and then the back end.

Referring to the first to fifth figures, the electronic card connector assembly of the present invention is used to house the electronic card 500, including the electronic card connector 100, the circuit board 200, and the tray 300. The electronic card connection The device 100 includes an insulative housing 1 , a conductive terminal 2 fixed in the insulative housing 1 , a shielding housing 3 disposed on the insulative housing and surrounding the receiving space, and a card ejection mechanism 4 and a detecting terminal disposed on the insulative housing 1 . 5.

Referring to the fourth and fifth figures, a plurality of terminal receiving grooves 11 and a receiving portion 12 provided at the front end are disposed in the middle of the insulative housing 1.

The conductive terminal 2 is held in the terminal receiving groove 11 and includes a contact portion 21 , an elastic portion 22 extending obliquely downward from the contact portion 21 , a frame-shaped holding portion 23 embedded in the insulating body 1 , and a welded portion 24 . Referring to the sixth figure, the elastic portion 22 has one end connected to the holding portion 23 and the other end having a free end 25, and the free end 25 is suspended from the circuit board 200 in the unfed state. The contact portion 21 and the elastic portion 22 form an arch structure, and the contact portion 21 protrudes from the upper surface of the insulative housing 1 to be in contact with the electronic card 500. The contact portion 21 and the elastic portion 22 ensure the elasticity of the conductive terminal 2 during contact with the electronic card 500.

The shielding shell 3 has a top wall 31 , a fastening portion 32 formed by bending downward along the top wall 31 , and a detecting portion 33 disposed at the front end and the detecting terminal 5 . The latching portion 32 is buckled on both sides of the tray 300 and the middle portion thereof is bent inward to form a pressing portion 321 .
