GENDER CHANGER INVOLVING SPARE BATTERY FOR PORTABLE TELEPHONE

摘要

The present invention relates to a mobile phone gender with a built-in auxiliary battery, a 20-pin male connector inserted into the 20-pin female connector of the mobile phone; A 24-pin female connector connected to a 24-pin male connector of a charging cable and a data transmission cable; A PCM (Protection Circuit Module) board connected to the 20-pin male connector and the 24-pin female connector and responsible for preventing overload power and controlling data transmission; A secondary battery connected to the PCM substrate; A lower housing accommodating the 20-pin male connector, a 24-pin female connector, a PCM board, and an auxiliary battery; And an upper housing coupled to one side of the lower housing and provided to be opened and closed.;As a result, a built-in auxiliary battery can be used to provide an auxiliary charging power source, to ensure easy portability, and to identify whether there is a connection when connecting an external cable to a mobile phone, errors in data transmission, and non-charging. In addition, by providing a protection circuit against external overload voltage, it is possible to reduce the possibility of a failure of the mobile phone, and is provided with a protective cover of a 24-pin female connector exposed to the outside can reduce the possibility of failure of gender.;Gender, Secondary Battery, Mobile Phone
