The invention discloses a mobile phone card holder having a fool-proof function. The mobile phone card comprises a shell, an insulator layer, a card carrier, and a printed circuit board (PCB), wherein a first pin, a second pin, a third pin, and a fourth pin are arranged on the shell, a first card carrier slot, a first card carrier fool-proof slot, a second card carrier slot, a second card carrier fool-proof slot, a third card carrier fool-proof slot and a third card carrier slot are formed in the bottom of the insulator layer, the card carrier comprises a TransFlash (TF) card slot and a small subscriber identity module (SIM) card slot, the insulator layer is connected with the top end of the PCB, the left and right ends of the insulator layer are provided with a first terminal and a second terminal respectively, the top end of the shell is rotatably connected with the insulator layer to form accommodating space, the first pin, the second pin, the third pin, and the fourth pin are clamped in a first inserting hole, a second inserting hole, a third inserting hole, and a fourth inserting hole respectively, the card carrier is located in the accommodating space, and the left side edge of the card carrier can slide along a push rod. According to the mobile phone card holder having a fool-proof function, the car carrier is easy to install, and installation efficiency is high.
Description
[0001] technical field [0002] The invention relates to a card holder for a mobile phone, in particular to a card holder for a mobile phone with a fool-proof function. Background technique [0003] With the continuous progress of science and the continuous development of communication tools, the structure, style and performance of mobile phones are more and more frequent, and people's requirements for mobile phones are also getting higher and higher. For general mobile phone applications, most of the SIM (Subscriber Identity Module) cards are inserted into the card slot of the mobile phone, and after the activation procedure is completed, the mobile phone can be used to receive and make calls. Many existing mobile phones have dual-card dual-standby or dual-network dual-standby functions, that is, two small SIM cards or a TF card and a small SIM card are simultaneously installed in the card tray of a mobile phone card holder. , and in the assembly process of the mobile ph...
