Description

Card holder for mobile terminal and mobile terminal

technical field

The invention relates to the field of electronic products, in particular to a deck for a mobile terminal and the mobile terminal.

Background technique

Mobile communication technology has entered the digital age from the analog era. After experiencing 1G, 2G, 3G, and 4G communication technologies, the requirements for voice and data transmission quality and transmission speed are getting higher and higher during calls. SIM cards are often used in mobile terminals. to identify and differentiate end users.

SIM card is the abbreviation of (Subscriber Identity Module customer identification module), also known as subscriber identity card, smart card, GSM digital mobile phone must be equipped with this card before it can be used. The SIM card stores the information of the digital mobile phone customer, the encrypted key and the user's phone book, etc., which can be used to identify the identity of the GSM network customer and encrypt the voice information of the customer during the call.

The SIM card is an essential identification card for the mobile terminal to carry out mobile communication, and the mobile terminal must be loaded with the SIM card before it can be used.

At present, there are two main methods for loading a SIM card into a mobile terminal:

1. Some mobile terminals need to open the back cover of the terminal and install the SIM card at the reserved SIM card installation position. This method makes the operation of installing the SIM card more cumbersome.

2. In some mobile terminals, the back cover is not detachable, and the SIM card is loaded on the side of the mobile terminal. As shown in Figure 1, the SIM card tray 101 for placing the SIM card is placed in the mobile phone 102. Install the SIM card; take and place the SIM card using the principle of leverage; The remaining through hole 104 presses one end 105 of the lever 106, and the lever 106 rotates outward under the action of the rotating shaft 107, thereby pushing the SIM card tray 101 out of the mobile phone. However, this method of pushing out the SIM card tray must rely on the thimble 103 or other substitutes. This thimble 103 is relatively sharp, which is inconvenient and not safe to carry. It is also easy to forget or lose it. When there is no thimble 103, it cannot be taken out. SIM card.
