Structure for preventing subscriber identity module (SIM) card from being hot-plugged

Abstract

The invention discloses a structure for preventing a subscriber identity module (SIM) card from being hot-plugged. The structure comprises a mobile terminal enclosure, a battery slot and the SIM card, wherein the SIM card and the battery slot are arranged according to a preset distance; the SIM card is arranged in an SIM card slot; a slot body is formed in the mobile terminal enclosure along the direction of the SIM card slot; a hinging piece for pressing against the edge of the SIM card is arranged in the slot body; the hinging piece has an arm part which is inserted into the battery slot and pressed by a battery; the front end of the hinging piece is provided with a wall blocking part which presses against the edge of the SIM card; and the hinging piece is arranged at a position, close to the edge of the battery slot, in the slot body through a hinging shaft. A hinging piece structure for pressing against the edge of the SIM card is arranged in the mobile terminal enclosure, so, during installation of the battery, the battery downwards presses the arm part of the hinging piece, the hinging piece is rotated and the wall blocking part is moved upwards to close an entrance and exit for the SIM card; therefore, the SIM card cannot be taken out again and effectively prevented from being hot-plugged to prevent a chip from being burnt.

Description

technical field [0001] The invention relates to the field of mobile terminals, and more specifically, relates to a structure for preventing hot plugging of SIM cards. Background technique [0002] SIM (Subscriber Identity Module) card, also known as "Subscriber Identity Card", is dedicated to mobile phones of digital (GSM) system. When developing the GSM system in Europe, in order to improve the shortcoming that analog mobile phones are easy to be stolen, they developed it with the concept of credit card, thus forming the concept of SIM card. SIM card is a kind of micro-processing chip, which stores the relevant identification data of mobile phone users on the communication network, such as mobile phone number, communication parameters, etc., and the remaining extra space can also store personal phonebook or other personal data. [0003] Since the SIM card is an IC chip, in order to prevent damage, you must pay attention to the following items: 1. Try not to touch the metal...

Problems solved by technology

This makes some cases where the Sim cannot get the ideal position for the above two situations

[0008] like image 3 As shown, the SIM card 200 is located on the side of the battery 100 but not close to the battery 100, the limiting structure 300 can only realize the positioning function of the SIM card 200 itself, that is, the SIM card 200 will not fall out under the action of external force

But because the SIM card 200 is not close to the battery 100, there is no battery 100 to limit the SIM, and the SIM card 200 can also be taken out without taking out the battery 100, so that when the mobile terminal is not powered off, the SIM card 200 The chip is burned due to being plugged or hot-swapped

[0009] Therefore, prior art still needs to improve and develop
