DETAILED DESCRIPTION

[0032] Please refer to Figures 1-5 The embodiment is a new type of laminated card seat connector 100, which comprises a lower terminal assembly 2 welded on a PCB 1, an upper terminal assembly 3 surrounding the lower terminal assembly 2 and forming a plug cavity 4 with the lower terminal assembly 2, a card holder 6 inserted into the plug cavity 4, a card ejecting module 5 arranged at the front end of the plug cavity 4 and ejecting the card holder 6 from the plug cavity 4, and a detection terminal 7 clamped at the front end of the upper terminal assembly 3. The card holder 6 is formed with a first card slot 61 and a second card slot 62 arranged in layers and used for placing SIM cards. A metal partition 63 is arranged between the first card slot 61 and the second card slot 62 and used for supporting the SIM cards. The metal partition 63 is provided with a contact part 631 extending out of the front side wall 65 of the card holder 6. The card ejecting module 5 pushes the contact part 631 to eject the card holder 6.

[0033] The metal partition 63 is embedded in the inside of the card holder 6 by injection molding. Therefore, the metal partition 63 is provided with a plurality of clamping blocks 633, and the card holder 6 is correspondingly provided with a plurality of clamping slots matched with the clamping blocks 633. The clamping blocks 633 and the clamping slots are matched with each other, so that the metal partition 63 is embedded in the inside of the card holder 6 and the metal partition 63 is integrally formed with the card holder 6. The embedded metal partition 63 of the card holder 6 can increase the strength of the card holder 6. In order to facilitate the taking out of the SIM cards in the first card slot 61 and the second card slot 62, the front side wall 65 of the card holder 6 is provided with avoiding slots 64 on the upper and lower surfaces, which are used for facilitating the taking out of the SIM cards. The side edge of the SIM card contacted by the hand inserted into the avoiding slots 64 can be conveniently taken out. The metal partition 63 is provided with an avoiding opening 632 in the middle, which is used for facilitating the taking out of the SIM cards. If there is only a SIM card placed in the first card slot 61 or the second card slot 62, the hand inserted into the avoiding opening 632 can also conveniently take out the SIM card.

[0034] The lower terminal assembly 2 comprises a first plastic body 21 integrally overmolded, a first metal terminal 22 embedded in the first plastic body 21 and externally exposing the connecting points.

[0035] The upper surface of the upper terminal assembly 3 is pasted with a shell 8 for preventing short circuit by adhesive tape, and the pasted shell 8 can prevent the card seat connector from short circuit. The upper terminal assembly 3 comprises a second plastic body 31 integrally overmolded, a second metal terminal 32 embedded in the second plastic body 31 and externally exposing the connecting points, a metal shell 33 wrapped around the outer periphery of the second plastic body 31 and forming the insertion cavity 4 with the lower terminal assembly 2, and the second metal terminal 32 and the metal shell 33 are both welded to the PCB board 1.

[0036] The detection terminal 7 is clamped at the front end of the second plastic body 31, and the welding pin 71 at the lower end of the detection terminal 7 is welded to the PCB board 1. The detection terminal 7 is arranged between the front end of the card holder 6 and the second plastic body 31. When the card holder 6 is inserted or the card seat connector is subjected to impact test, the card holder 6 may be over-inserted to deform the detection terminal 7, causing the welding pin 71 of the detection terminal 7 to crack, and thus the detection terminal 7 loses its function. In order to solve this problem, the metal shell 33 is provided with a limiting baffle 331 extending into the insertion cavity 4, and correspondingly, the front end of the card holder 6 is provided with a limiting groove 66 cooperating with the limiting baffle 331. When the card holder 6 is inserted into the insertion cavity 4 or subjected to impact test, one side of the limiting baffle 331 abuts against the groove wall of the limiting groove 66, limiting the card holder 6 from being continuously inserted forward, thereby preventing the card holder 6 from being over-inserted to deform the metal shell 33 and the detection terminal 7.

[0037] The card ejecting module 5 comprises a support 51 located at the front end of the insertion cavity 4, a rotating shaft 52 hingedly and rotatably arranged on the support 51, and a push rod 53 extending into one side of the upper terminal assembly 3 and buckling one end of the rotating shaft 52. The push rod 53 is used to drive the rotating shaft 52 to push the card holder 6 backward to exit the insertion cavity 4. One end of the rotating shaft 52 extends out of the side edge of the card holder 6 for the push rod 53 to act, and the other end extends into the front side of the card holder 6 and acts on the contact portion 631. When the push rod 53 pushes one end of the rotating shaft 52 forward, the rotating shaft 52 rotates around the support 51, and the other end of the rotating shaft 52 contacts the contact portion 631 on the front side of the card holder 6 to thereby push the card holder 6 outward. Since the contact portion 631 is made of metal and the rotating shaft 52 is also made of metal, when the rotating shaft 52 abuts against the contact portion 631 to push the card holder 6 outward, the rotating shaft 52 can avoid directly contacting the card holder 6 to deform the card holder 6, and the problem that the front side of the card holder 6 is deformed or recessed to shorten the ejection stroke of the rotating shaft 52 and thus affect the ejection action of the card holder 6 can be solved.

[0038] The novel laminated card seat connector 100 can solve the problem that the top of the card holder 6 is deformed or recessed, the ejection stroke of the rotating shaft 52 is shortened, and the ejection action of the card holder 6 is affected; the over-insertion of the card holder 6 can be prevented, so that the problem that the over-detection terminal 7 is deformed by collision can be solved; the SIM card in the first card slot 61 and the second card slot 62 can be taken out more conveniently; and the card seat connector can be prevented from short circuit.

[0039] The above only describes some embodiments of the present application. Those skilled in the art can make some modifications and improvements without departing from the inventive concept of the present application, and these modifications and improvements are within the protection scope of the present application.
