Capacity expanding mobile phone casing

Abstract

The invention relates to the electronic technology field, especially relates to a capacity expanding mobile phone casing. The capacity expanding mobile phone casing comprises a main body, in which is disposed a cavity used for accommodating a cell phone. The lower end of the casing is provided with a capacity expanding part used for accommodating a component. A chip used for increasing the internal memory capacity of the cell phone is disposed in the capacity expanding part. The chip is connected with a plugging part cooperated with the charging jack of the cell phone, and the plugging part is connected with the chip, and then the chip is the external capacity part of the cell phone. The capacity expanding mobile phone casing is advantageous in that the capacity expanding chip is connected with the plugging part cooperated with the charging jack of the cell phone, and the capacity expanding of the cell phone is realized; the capacity expanding part is disposed in the cell phone casing, and the normal use and the carrying of the cell phone are not affected; and at the same time, the capacity expanding part is provided with the charging jack and an earphone cable jack, and then the capacity expanding chip is not required to be detached during charging and other conditions; a use is simple and convenient, use performance is high, and continuous capacity expanding is realized.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an expanded mobile phone case. Background technique [0002] The memory capacity of existing mobile phones is limited when leaving the factory, but with the upgrade of the system during use, its own capacity is getting larger and larger, causing the storage capacity of the mobile phone to continuously weaken, affecting normal performance. In addition, there are USB flash drives on the market that can externally expand the capacity of mobile phones, but they need to be inserted when they are in use. If they are usually inserted, they will affect the normal use of the mobile phone, which is extremely inconvenient, and they must be pulled out during the charging process. . Contents of the invention [0003] The object of the present invention is to provide an expanded mobile phone case that can greatly improve the performance and continuously expand the capacity in order to s...
