Background technique

Now we generally use ordinary sockets in our families, that is, there are only ordinary jacks on the plastic shell panel of the socket, which can only be used with matching ordinary plugs. There are more and more high-tech electronic devices such as mobile phones, MP3, MP4, MP5, PSP, tablet computers, especially mobile phones, almost everyone has them, and these high-tech electronic devices need electricity, and their charging methods It is to use the USB data cable to cooperate with the AC power supply to charge. Generally, the charging method includes a socket for inserting an electronic product, a USB connector, a charging module, and a plug for inserting into a socket. And although the volume of existing charger is not big, existing charging standard is not unified and causes different electronic products to need to be equipped with different chargers, causes portability like this. Therefore, many people often only carry charging cables to charge on electronic devices with USB ports such as desktop computers and notebook computers. However, if the moving light device is turned on exclusively for charging small electronic devices, power will be wasted.

At the same time, existing electronic devices all have the phenomenon of overcharging during the charging process. If the battery of the electronic product is in an overcharged state for a long time, the service life of the battery will be seriously affected.

Therefore, there is a need for a socket with a dedicated USB socket and capable of preventing electronic products from being overcharged to solve the problems in the prior art.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model proposes a USB multifunctional socket with a charging indication, and provides a power conversion socket with rich functions and capable of charging electronic products, so that it is convenient for users to use.

A USB multifunctional socket with charging indication described in the utility model comprises a housing, a circuit board, a USB jack, an LED indicator light, a control switch and a charging control module;

The LED indicator light includes an LED night indicator light and an LED work indicator light, the LED night indicator light is used for night lighting, and the LED work indicator light is used to indicate the charging state;

The LED working indicator light is displayed as two different colors according to the charging state, one color is displayed when charging, and another color is displayed after charging is completed; the LED night indicator light is displayed as another third color;

There are two control switches, which respectively control the LED night indicator light and the LED work indicator light;

The circuit board is connected with a mains plug for connecting to an external mains, and the USB jack, LED indicator light, and control switch are evenly arranged on the housing; the circuit board, the charging control module, and the USB jack , the LED work indicator light and the control switch of the LED work indicator light are sequentially electrically connected to form a loop, and the circuit board, the LED night light indicator and the control switches of the LED night light indicator are sequentially electrically connected to form a loop.

Further, the said USB multi-functional socket with charging indication is provided with a jack seat, and said jack seat is provided with a three-prong jack or a double-prong jack, or a triple-prong jack and a double-prong jack at the same time.

The number of USB jacks is greater than or equal to 1.

The socket also includes a protective cover, which can effectively prevent dust or other foreign matter from entering the USB socket and the common socket, so as to ensure the safe use of the socket.

The beneficial effect of the technical solution described in the utility model is that: by setting the charging module and the USB interface for charging on the basis of the traditional socket, the mobile phone and other electronic devices can be charged as long as there is a USB charging line without a charger; The function of the mains socket and the USB charging interface expands the use function of the socket and improves the efficiency of the socket; through the charging process indicator light, it can conveniently and effectively remind the charging state of the charger, prevent the battery from being overweight, and reduce the The service life of the battery; by setting a luminous film on the socket switch, it is convenient to perform corresponding operations at night; by setting the LED work indicator light to control the switch to determine whether to connect to the mains, to ensure the safety of electricity use, and to avoid frequent plugging and unplugging the socket head. The service life of the socket; by setting a protective cover on the socket, it can effectively prevent dust or other foreign matter from entering the USB jack and ordinary jack, ensuring the safe use of the socket.
