Problems solved by technology
However, in the era of thin and light mobile phones, the internal space of the mobile phone is very expensive. Due to the complicated circuit layout in the existing mobile phone card holder, the installation space is limited, and the installation of two SIM cards and a memory card at the same time will lead to the overall thickness of the mobile phone card holder. increase, which is not conducive to the miniaturization and thinning of mobile phones

Abstract
The invention relates to a double-layer mobile phone holder. The holder comprises an iron shell, an upper layer body, a card base, a lower layer body and a PCB (printed circuit board). The upper layer body is provided with SIM (subscriber identity module) card terminal pins, the lower layer body is provided with SIM card terminal pins and memory card terminal pins, the double-surface structures of the SIM card or the memory card can be placed on upper and lower surfaces of the card base, the card base is placed between the upper layer body and the lower layer body to form a card slot, the upper end of the card slot is provided with the iron shell and the card slot is connected with the PCB. Pluggable connection is adopted between the upper layer body and the lower layer body, the PCB is the U-shaped structure, the card slot is placed at the centre of the U-shaped structure and contacts with contacts on three edges of the PCB. Through the design, the SIM card or the memory card is respectively placed on upper and lower surfaces of the card base and convenient to extract and exchange, user requirements are met, and the space is greatly saved; SIM and TF card terminals on the lower layer body are configured so that the user can flexibly select the model of SIM card + SIM card or the model of SIM card + memory card, and the double-layer mobile phone holder is simple in structure, saved in space, convenient, flexible, steady and reliable.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a double-layer mobile phone deck. Background technique [0002] With the development of science and technology, mobile phones have become an indispensable part of modern life. In order to realize the functions of the mobile phone, it is usually necessary to use a SIM card (Subscriber Identity Model, Subscriber Identity Module) in the mobile phone system. There are multiple bare points on the SIM card, which can be electrically connected to the terminals on the SIM card holder inside the mobile phone, so as to realize functions such as calling and storing information. [0003] Due to the needs of life or work, people often have multiple numbers, which requires the mobile phone to be able to insert multiple SIM cards, and with the development of the information society, the mobile phone is not just a tool for calling, and the application of the mobile phone in life is...
