Description

Mobile terminal

Technical Field

The invention relates to the technical field of mobile equipment, in particular to a mobile terminal.

Background

Currently, a smart mobile terminal generally employs a card holder type clamping device disposed at a side portion to position a user card (such as a SIM card and/or a memory card) into the mobile terminal, where the card holder type clamping device generally includes a card holder for carrying the user card and sliding in the base, and a card holder support for accommodating the card holder, locking the card holder, and a mechanism for ejecting the card holder is disposed on the card holder support. When the user card needs to be taken out, the ejector pin needs to be inserted from an ejector pin hole arranged on the mobile terminal shell, and the ejector pin pushes the mechanism for ejecting the card support, so that the card support is released from the card support bracket and is ejected out of the mobile terminal shell.

The SIM card is I C cards held by mobile subscribers of the GSM system, called subscriber identity cards. The GSM system identifies the GSM user through the SIM card. The same SIM card can be used on different handsets. The GSM mobile phone can access to the network for use only after the SIM card is inserted; the SIM card is a key for a GSM handset to connect to a GSM network, and once the SIM card is pulled from the handset, the handset will not be able to enjoy the various services provided by the network operator, except for emergency calls. The SIM card can be used as a key, and provides many convenience for the user. The user can realize communication only by inserting or embedding the SIM card into any one GSM terminal. The SIM card also manages a number of information that is provided to the subscriber's service and can be used to store short messages, particularly those that are received when the subscriber is not on or at work. The memory card is mainly used for expanding and increasing the upper limit of the memory of the mobile terminal, such as a TF card, an MMC card, an SD card and the like, and is used as the memory card for the mobile terminal.

The mode of inserting the thimble to realize card taking requires that a user carries the thimble at any time, otherwise, the user card cannot be taken out, the operation is inconvenient, and the user experience is influenced; in addition, the top pinhole is easy to allow some impurities such as dust and liquid to enter the shell of the mobile terminal.
