Description

A mobile phone protective case with interface conversion function

technical field

The utility model relates to a protective shell for digital products such as a mobile phone and a tablet computer, in particular to a protective shell for a mobile phone with an interface conversion function.

Background technique

The Apple iPhone 7 mobile phone uses the lightning data interface. The Lightning interface is an all-digital interface with adaptive functions, which can realize functions such as charging, high-speed data synchronization, audio output, and playback control. However, the Lightning interface is not compatible with the original Apple mobile phone. The 30Pin interface earphones are not compatible with the 3.5mm earphone interface and the Android data cable interface, which is inconvenient to use.

In particular, existing audio and video equipment such as audio equipment and video equipment are generally analog input equipment. If the Lightning interface is used, a "digital-to-analog converter (DAC)" must be added to realize this, which will inevitably lead to increased user costs.

The technical scheme that the utility model solves its technical problem adopts is:

A protective case for a mobile phone with an interface conversion function, comprising a housing, the housing is provided with a plug connector corresponding to the data port of the mobile phone, and the housing is provided with an earphone interface and a charging interface electrically connected to the plug connector .

The plug connector is injection-molded on the housing.

The earphone jack is a 3.5mm earphone jack; the charging interface is one or more of USB interfaces.

The housing is provided with a data conversion module electrically connected to the plug connector, the earphone jack and the charging jack.

The data conversion module includes an A/D conversion module.

A coupling coil electrically connected to the plug connector or the data conversion module is arranged on the housing.

The housing is provided with a first permanent magnet, and the back of the housing is provided with an electrical connection panel electrically connected to the plug connector or the data conversion module.

The electrical connection panel includes several concentric conductive rings insulated from each other.

The back of the casing is provided with a first concave, and the electrical connection panel is embedded in the first concave.

There are four first permanent magnets, and four second indentations arranged in a square are arranged on the front of the housing, and the four first permanent magnets are respectively embedded in the four second indentations.

The beneficial effects of the utility model are: the casing of the utility model is provided with a plug joint, an earphone interface and a charging interface, and the earphone interface and the charging interface are popular universal interfaces. After the protective case is set on the mobile phone, the plug joint is naturally inserted into the mobile phone In the data port, through the data conversion module, the specialized interface of the Apple iPhone 7 mobile phone is converted into a popular general-purpose earphone interface and charging interface, so that the Apple iPhone 7 mobile phone can be compatible with the current general-purpose earphones and data lines, and can reduce The user's cost saves social resources.
