Problems solved by technology

[0002] The SIM card and SD card in the communication terminal equipment are assembled in a card tray, the SIM card is inside, and the SD card is outside. This card tray structure design, in the process of pulling out the card tray, the power pin of the SIM card will touch to the ground pin of the SIM card, and the ground pin of the SD card will touch the data signal of the SIM card. If the SD card is not powered off in time, it will cause the SIM card to burn.

Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0023] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first card slot could be termed a second card slot, and, similarly, a second card slot could be termed a first card slot, without departing from the scope of the present application. Both the first card slot and the second card slot are card slots, but they are not the same card slot.

Abstract

The invention relates to a method and device for preventing a SIM card from being burned and a computer device. The method for preventing the SIM card from being burned is characterized by including the steps that based on a terminal internally provided with a power management module and a card support, a conductive unit which can be in contact with a power supply pin of a SD card is arranged on the card support; the power management module detects the instantaneous voltage of the SD card; according to the instantaneous voltage when the power supply pin of the SD card is in contact with the conductive unit, the inserting-pulling state of the SD card is detected; when the SD card is in the pulling state, the power management module is triggered to power off power supply of the SD card. According to the method, the inserting-pulling state of the SD card is detected according to the instantaneous voltage when the power supply pin of the SD card is in contact with the conductive unit through the power management module, and when the SD card is in the pulling state, the power management module is triggered to further rapidly and effectively power off the power supply of the SD card, thehardware triggering mode is adopted, and powering off is timely; meanwhile, under the condition of reliable powering off is guaranteed, a power control circuit additionally arranged on the card support can also be saved, and the cost is saved.

Description

technical field [0001] The present application relates to the technical field of terminal card holders, in particular to a method, device and computer equipment for preventing SIM card from burning. Background technique [0002] The SIM card and SD card in the communication terminal equipment are assembled in a card tray, the SIM card is inside, and the SD card is outside. This card tray structure design, in the process of pulling out the card tray, the power pin of the SIM card will touch to the ground pin of the SIM card, and the ground pin of the SD card will be in contact with the data signal of the SIM card. If the SD card is not powered off in time, it will cause the SIM card to burn. Contents of the invention [0003] Embodiments of the present application provide a method, device and computer equipment for preventing SIM card burning, which can effectively prevent SIM card burning with low cost. [0004] A method for preventing SIM card burning, based on a termina...
