Problems solved by technology

[0002] In the existing SIM card holder, when the battery is not pulled out, the SIM card holder is powered on. When the customer takes out or puts in the SIM card, it is easy to burn the card. The reason is that when the customer removes and installs the card, the SIM The card holder is still in the power-on state. At this time, plugging and unplugging with power will cause an instantaneous arc between the gold-plated area of ​​the SIM card and the signal pin, which will cause the contact area to burn and cause the customer to be unable to read the card when using the mobile phone.

Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] A preferred embodiment of the present invention provides a mobile terminal with a SIM card socket. Such as Figure 1 to Figure 2 , The SIM card holder includes a base 1, a signal spring foot 2, a detection device 3, and a controller (not shown in the figure). The signal spring 2 is arranged on the base 1 and is connected to a power supply module (not shown in the figure) for reading and writing information of the SIM card 9. The ...

Abstract

A mobile terminal includes a SIM card holder and a controller, and the SIM card holder includes a base, a signal spring and a detection device. The detection device is used to cooperate with the end of the SIM card, and it includes a fixed foot and a detection spring foot, and the clutch between the two can detect the action of the SIM card. The trigger part of the detection spring can abut against the end of the SIM card to convert the movement of the second end of the detection spring, and the trigger part is closer to the bearing surface relative to the contact part. During the process of taking out or installing the SIM card, the SIM card can move the second end of the detection spring foot and trigger the clutch change between the detection spring foot and the fixed foot. The controller can turn off the power supply of the signal spring foot before the SIM card is separated from the signal spring foot Cut off, and can turn on the power of the signal spring after the SIM card and the signal spring touch each other, the controller will turn on and off the power in a timely manner, effectively avoiding the instantaneous arc between the SIM card and the signal spring when it is loaded or taken out and burned .

Description

Technical field [0001] The invention relates to the field of mobile communication equipment, and in particular to a mobile terminal. Background technique [0002] With the existing SIM card holder, the SIM card holder is energized without removing the battery. When the customer removes or inserts the SIM card, it is easy to burn the card. The reason is that when the customer takes the card and installs the card, the SIM card The card holder is still energized. At this time, plugging and unplugging will cause instantaneous arcs between the gold-plated area of ​​the SIM card and the signal pins, which will cause the contact area to burn out and cause customers to be unable to read the card when using the mobile phone. Summary of the invention [0003] The invention provides a SIM card holder and a mobile terminal with the SIM card holder, which can prevent the SIM card from being burned when the card is taken out and installed. [0004] In one aspect, a SIM card holder is provided, w...
