[0024] The card holder 10 includes an insulating seat body 11, a plurality of conductive terminals 12 arranged on the insulating seat body 11, and a metal shell 13 that wraps the insulating seat body 11. The insulating seat body 11 includes a bottom wall 111, a rear wall 112 extending upward from the rear end of the bottom wall 111, and a slot 113 formed between the bottom wall 111 and the rear wall 112. The metal shell 13 includes a bottom wall (not shown) and two side walls 132 extending upward from the left and right ends of the bottom wall. A fixing groove 114 is provided on the top surface of the rear wall 112 to fix and accommodate the magnet 30 and the coil 40. The slot 113 is also located between the two side walls 132. The conductive terminal 12 includes a plurality of contact portions 121 located in the slot 113 and a plurality of welding portions 122 extending from the insulating seat body 11. The welding portions 122 are arranged in a row and located on the upper surface of the rear wall 112.

[0025] The card tray 20 is inserted and pulled out of the slot 113 of the card holder 10, and the insertion and removal force points are eliminated between the card holder 10 and the card tray 20. The card tray 20 includes a main body 21 and a door panel 22 connected to the front end of the main body 21. The main body 21 is provided with a card slot 210 for loading the electronic card 300. The magnet 50 is a rectangular bar extending left and right, and is fixed to the rear or back end of the main body 21 by assembly or insertion molding. The magnet 50 is exposed on the rear end surface of the card tray 20. The magnetic poles of the magnet 50 are arranged front and back, with the N pole in front and the S pole in the back, or the S pole in front and the N pole in the back.

[0026] The magnet 30 is a rectangular strip extending left and right, and is provided with a front flange 31, a rear flange 32 and an annular recess 33 between the front flange 31 and the rear flange 32. The front flange 31 and the rear flange 32 are respectively annular.
