As shown in fig. 1, an embodiment of the present invention provides a card socket 100, including: the card holder comprises a card holder body 10, a first terminal group 20 and a second terminal group 30, wherein the card holder body 10 is provided with a first card slot 11 and a second card slot 12, the first card slot 11 and the second card slot 12 are separated by a first cross beam 13, the first terminal group 20 is arranged in the first card slot 11 to form a first card holder 40, and the second terminal group 30 is arranged in the second card slot 12 to form a second card holder 50.
In the embodiment of the present invention, the card socket body 10 is made of an insulating material, and since the card socket body 10 needs to be inserted into and pulled out from the card holder to be butted, the card socket body 10 should have certain structural strength and wear resistance. The card seat body 10 is provided with a first card slot 11 and a second card slot 12, and the first card slot 11 and the second card slot 12 are separated by a first beam 13, that is, the first card slot 11 and the second card slot 12 share the first beam 13. The card holder body 10 with the first card slot 11 and the second card slot 12 can be produced through an injection molding and integral forming process; the card socket body 10 with the first card slot 11 and the second card slot 12 can also be produced by a stamping forming mode.
By assembling the first terminal set 20 within the first card slot 11, the first card socket 40 may be formed; the second card socket 50 may be formed by assembling the second terminal set 30 in the second card slot 12. In the present embodiment, the first card socket 40 is a T-card socket, that is, the first terminal set 20 is a T-card terminal set; the second card socket 50 is a SIM card socket, that is, the second terminal set 30 is a SIM card terminal set. The T card socket and the SIM card socket of the card socket 100 may be butted with a T card and a SIM card loaded on a card holder to implement functions of the T card and the SIM card. When the card holder 100 is disposed on the circuit board, one end of the card holder 100, on which the T-card is disposed, faces the insertion/extraction opening for the card holder on the mobile terminal.
Through the structural improvement, namely, the first clamping seat 40 and the second clamping seat 50 share the first beam 13, compared with the prior art, the T-shaped clamping seat is adjacent to the SIM card seat and arranged on the circuit board in a spaced mode, the distance between the first clamping seat 40 and the second clamping seat 50 can be effectively reduced, the mounting space required by the clamping seat 100 is further reduced, and the development trend that the functions of the mobile terminal are more and more rich is met.

It should be noted that, in the internal structure of the mobile terminal, the positions of the T card and the SIM card are determined by the positions of the T card socket and the SIM card socket, so the distance between the T card socket and the SIM card socket determines the distance between the T card and the SIM card. At present, the safety clearance distance between the T card holder and the SIM card holder which are mainstream in the market is 0.30 mm, and the distance reaches the limit of the processing and placing precision of the paster. In the embodiment of the present invention, the patch safety gap between the split T-card socket and the SIM card socket, and the respective beam and the patch pad can be integrated into the first beam 13, so as to reduce the distance between the first card socket 40 (T-card socket) and the second card socket 50(SIM card socket), further reduce the installation space required by the card socket 100, and meet the development trend of more and more rich functions of the mobile terminal.
Optionally, at least one pad 14 is disposed on the socket body 10.

Furthermore, a pad 14 may be disposed in a middle portion of the first beam 13 in the length direction, the pad 14 is disposed toward one side of the second card socket 50, and is partially located in the second card slot 12, where the second card socket is a SIM card socket, which is equivalent to disposing the pad 14 in a central position of the card socket body 10. Through the layout mode, the pad 14 is arranged on the card seat body 10, namely, the pad 14 is arranged in the middle of the card seat body 10, so that the stability of the whole card seat 100 in the process of being connected with a circuit board can be improved. Thus, the mounting fixation with the circuit board is realized through the plurality of bonding pads 14, the mounting strength of the card holder 100 and the circuit board can be improved, and the risk of displacement of the card holder 100 on the circuit board in the working process can be reduced.
It should be noted that, by disposing the pads 14 on both sides of the card socket body 10 and at both ends of the first beam 13 in the length direction, the size of the card socket 100 in the length direction can be further reduced compared to disposing the pads 14 in the length direction of the card socket body 10, and the occupied space of the card socket 100 in the mobile terminal can be reduced. Wherein, the length direction of the card seat body 10 is the plugging direction of the card support. And a preset distance is reserved between the edge of the first card holder 40 and the edge of the second card holder 50, and the edge of the pad 14 does not exceed the edge of the first card holder 40 or the edge of the second card holder 50, so that no additional space is occupied.
