Embodiment 1

[0021] Such as figure 1 As shown, the base 1 of the SIM card holder of the first embodiment specifically includes: additional metal shrapnel 11, SIM card metal contacts 12, second fixed metal feet 13, first fixed metal feet 14, and corresponding card positions on the side of the base 15 and the hole 16 below the additional metal shrapnel.

[0022] In the first embodiment, the additional metal shrapnel 11 is connected to the second fixed metal foot 13, and the second fixed metal foot 13 is connected to the preset high-level interface of the mobile terminal. Specifically, the second fixed metal foot 13 can be The above-mentioned second fixed metal pin 13 is connected to the general purpose input / output (GPIO, General Purpose Input / Output) interface of the main chip through the wiring on the printed circuit board (PCB, Printed Circuit Board), and the GPIO interface is high power by default. Of course, in the first embodiment, the additional metal domes 11 can also be connected t...

Embodiment 2

[0027] The principle and structure of the second embodiment and the first embodiment are basically the same, as figure 2 As shown, with respect to the structure of the existing SIM card holder, an additional metal shrapnel 11 and a second fixed metal foot 13 are added to the base of the SIM card holder. The difference from Embodiment 1 is that the additional metal shrapnel 11 passes through another One way to achieve low level contact in the compressed state, specifically, the additional metal dome 11 is located in the base of the SIM card holder and adjacent to the grounding pin 17 in the metal contact, the additional metal dome 11 is in the SIM card When inserted, it is in a compressed state under the extrusion of the SIM card and is in contact with the ground pin 17 in the metal contact 12 of the SIM card.

[0028] While the additional metal dome 11 is not squeezed by the SIM card, its connection relationship is the same as that of the first embodiment. Therefore, the seco...

Abstract

Embodiments of the present invention provide a SIM card holder, a mobile terminal and a method for identifying hot plugging of a SIM card. In the prior art, the base of the SIM card holder is provided with a metal contact and a first contact connected to the metal contact. Fix the metal feet. On the basis of the prior art, the present invention sets an additional metal shrapnel on the base of the SIM card holder, which is used to be in an uncompressed state and contact high level when the SIM card is not inserted. Compressed state and contact low level, and pass its own high and low level to the main chip of the mobile terminal to identify the insertion and extraction of the SIM card. The invention relates to the field of mobile communication, which not only can identify whether the SIM card is inserted, but also does not need to add components, thereby further saving the space of the main board; at the same time, the production process is not affected, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of mobile communication equipment, in particular to a SIM card holder, a mobile terminal and a method for identifying hot plugging of a SIM card. Background technique [0002] With the rapid development of communication networks, mobile phones have become an indispensable electronic product in people's daily life. The requirements for mobile phones are becoming smaller and smaller, but their functions are becoming more and more diverse. Correspondingly, mobile subscriber identification cards ( The demand for SIM, Subscriber Identity Module) is getting higher and higher. A mobile phone is not only equipped with SIM card and Micro SD Card (micro SD card), but also has higher and higher requirements for hot plugging, and with Micro SD With the popularity of Card, the demand for the hot-swap function of the SIM card is becoming more and more urgent. [0003] At present, there are many mobile phones with hot-swappable SIM...
