[0028] See also Figure 1 and Figure 5 As shown, the electronic card connector 100 of the present invention is used to be installed in a portable electronic device such as a mobile phone to electrically connect an electronic card to the portable electronic device. The electronic card connector 100 includes a slot 10, an insulator 20, conductive terminals 30, detection terminals 40, a card tray 50, a card ejection mechanism 60, and a metal housing 70.

[0029] The slot 10 is formed in the metal housing 70 for inserting and removing the card tray 50 .

[0030] The insulator 20, conductive terminals 30, detection terminals 40, and metal housing 70 are integrally formed. A stopper 25 is located on the inside of the insulator 20, at the rear end of the card tray 50. This prevents the card tray 50 from over-inserting into the slot 10, preventing it from deforming the detection terminals 40 and metal housing 70 and potentially causing product failure.

[0031] The conductive terminal 30 includes a contact portion 31 extending downwardly and obliquely into the slot 10 and a soldering portion 32 extending out of the insulator 20 .

[0032] The detection terminal 40 includes a movable terminal 41 and a static terminal 42. The movable terminal 41 includes a fixed portion 411, an elastic arm 412 that bends inward and forward from one end of the fixed portion 411 and extends into the slot 10, a lap portion 413 at the end of the elastic arm 412, and a solder leg 414 that extends from the insulator 20 from the fixed portion 411. The lap portion 413 elastically abuts against the static terminal 42. When the card tray 50 is fully inserted into the slot 10, the rear end of the card tray 50 presses against the elastic arm 412, causing the lap portion 413 to move backward and separate from the static terminal 42, thus detecting that the card tray 50 is fully inserted.

[0033] See also Figures 6 to 9 As shown, the card tray 50 includes a cover 51, an insulating frame 52, a middle steel sheet 53, an upper card slot 54, and a lower card slot 55. The cover 51 is connected to the front end of the insulating frame 52 and is wider and thicker than the insulating frame 52. The upper card slot 54 is recessed in the upper surface of the insulating frame 52, and the lower card slot 55 is recessed in the lower surface of the insulating frame 52. The upper card slot 54 and the lower card slot 55 can simultaneously load electronics. The upper card slot 521 is located above the lower card slot 55. The middle steel sheet 53 is integrally formed with the insulating frame 52 to increase the structural strength of the card tray 50. The middle steel sheet 53 is located between the upper card slot 54 and the lower card slot 55.

[0034] The rear end of the insulating frame 52 includes a first corner portion 56 and a second corner portion 58 that are opposite each other. A first retaining groove 560 is provided on the upper surface of the first corner portion 56, and a second retaining groove 580 is provided on the lower surface of the second corner portion 58. The first retaining groove 560 and the second retaining groove 580 are each right-angled and laterally extend through the outer side surface and rear end surface of the insulating frame 52. In other embodiments, the first retaining groove 560 is provided on the lower surface of the first corner portion 56, and the second retaining groove 580 is provided on the upper surface of the second corner portion 58.

[0035] See also Figures 1 to 2 and Figures 4 and 5 As shown, the card ejection mechanism 60 includes a rotating shaft 61, a crank 62 and a push rod 63. The rotating shaft 61 is provided on the insulator 20 or the metal shell 70. The crank 62 is rotatably connected to the rotating shaft 61. One end of the crank 62 extends forward into the slot 10, and the other opposite end is overlapped with the push rod 63. The push rod 63 is set on the metal shell 70 for sliding back and forth, and is linked with the crank 62 to drive the crank 62 to push the card tray 50 forward to exit the slot 10.

[0036] Please combine Figures 10 and 11As shown, the metal housing 70 includes a first side wall 71, a second side wall 72, and a bottom wall 73 connecting the first and second side walls 71 and 72. The insulator 20 is molded on the inner surface of the bottom wall 73. The slot 10 is formed between the insulator 20, the first side wall 71, and the second side wall 72. A stopper 75 is provided at the rear of the first side wall 71, extending vertically from the inner side and separated from the bottom wall 73. The push rod 62 is slidably mounted on the second side wall 72. The bottom wall 73 has an opening 731 and an insert 732 connected to one of the inner edges of the opening 731. The plastic of the insulator 20 is filled in the opening 731. The stopper 25 is attached to the inner surface of the bottom wall 73. The insert 732 is embedded in the stopper 25 to increase its strength.

[0037] See also Figures 1 to 11 As shown, when the electronic card connector 100 of the present invention is in use, the card tray 50 loaded in the upper card slot 54 and the lower card slot 55 is inserted into the slot 10. The card tray 50 presses the elastic arm 412 of the movable terminal 41 backward, causing the overlap portion 413 and the static terminal 42 to change from contact to disconnection. The limiting block 75 enters the first limiting groove 560 of the card tray 50 forward, and the limiting boss 25 enters the second limiting groove 580 forward. The limiting block 75 cooperates with the first limiting groove 560, and the limiting boss 25 cooperates with the second limiting groove 580 to limit the movement of the card tray 50. During insertion and removal and impact testing of the electronic card connector 100, the card tray 50 is prevented from being over-inserted and deforming the detection terminal 40 and the metal housing 70, thereby ensuring the function of the electronic card connector 100.

[0038] In other embodiments, the limiting block cooperates with the second limiting groove, and the limiting boss cooperates with the first limiting groove, thereby preventing the card tray 50 from being over-inserted and deforming the detection terminal 40 and the metal shell 70, thereby ensuring the function of the electronic card connector 100.

[0039] Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
