Abstract

The invention provides a mobile terminal and a device for preventing an SIM (Subscriber Identity Module) from being subjected to hot plugging. The device comprises a locking piece arranged on the opening side of the SIM and locking the SIM, and further comprises a triggering unit and a reset unit, wherein the triggering unit is linked with the locking piece when the locking piece is driven to unlock the SIM, and the reset unit is used for transmitting a reset signal when the reset unit is electrically connected with the triggering unit. The mobile terminal and the device preventing the SIM from being subjected to the hot plugging can prevent the SIM from being subjected to the hot plugging so as to prevent the SIM from being damaged, and are simple in structure.

Description

technical field [0001] The invention belongs to the field of mobile terminals, in particular to a mobile terminal and a device for preventing hot plugging and unplugging of a subscriber identification card. Background technique [0002] The subscriber identification card may be called a smart card, and may be a SIM card, which is the abbreviation of Subscriber Identity Module (Customer Identification Module), and of course may be a UIM card, which is the abbreviation of User Identity Model (User Identity Module). Mobile terminals such as mobile phones and mobile phones must be equipped with this card before they can be used. However, during the communication process of the SIM card, if the SIM card is hot-swapped, that is, hot-swapped, it will easily cause damage to the data in the SIM card or even burn the SIM card. [0003] At present, when a mobile terminal uses an external battery, the battery is usually used to block the hot swap of the SIM card. That is, when the user...
