After connecting with the mobile phone to be charged through the charging plug line, it can charge 3-N mobile phone batteries at the same time. , from two aspects, it solves the embarrassing situation of charging difficulties caused by the lack of mains sockets and many mobile phone users in the environment, and provides convenience for mobile phone users who charge in concentrated places. the

The utility model achieves the above object through the following technical solutions: a multi-channel output mobile phone charger with a mains power transfer socket, including a casing, a functional circuit board, a power plug line, a mains power transfer socket, a USB charging socket and a charging Composed of status indicator lights, it is characterized in that: the rear of the charger casing is provided with a mains power transfer socket, a functional circuit board is installed in the casing, and USB charging sockets are respectively installed on the front and left and right ends of the casing. the

The functional circuit board is composed of AD power conversion circuit, intelligent charging management chip and auxiliary circuit components, and its function is to convert 110V-220V AC mains power into 5V DC low voltage through the AD power conversion circuit, and then provide it to the intelligent charging management The chip is charged and regulated to become a standard charging voltage of 4.2V, and then output to the outside through the USB charging socket welded on the circuit board, and provided to the mobile phone battery for charging. the

There are two sets of power-connecting metal clips inside the mains transfer socket, the internal structure of which is the same as that of the common mains socket, and the single-phase mains introduced is connected to other electric loads inserted into the socket. the

Beneficial effects produced by the utility model: the utility model is equipped with a mains power adapter socket outside the casing, which can provide power supply for other chargers while working, and the charger itself is equipped with multi-channel output USB charging The socket can provide charging power for 3-N mobile phones, which solves the embarrassing situation of charging difficulties caused by the lack of charging sockets and many mobile phone users in the local environment from two aspects, and provides convenience for mobile phone users charging in concentrated places . Embodiments of the utility model can be described in detail in conjunction with the accompanying drawings. the

Detailed ways

Known from Fig. 1, the utility model is a kind of multi-channel output mobile phone charger with mains power transfer socket, including casing 1, functional circuit board 2, power plug line 3, mains power transfer socket 4, USB charging socket 5. Charging status indicator light 6, charging plug connection 7, referring to Figure 1, the production and assembly process of the utility model charger is as follows: AD power conversion circuit, intelligent charging management chip, USB charging socket 5 and charging status will be installed. The indicator light 6 is welded and adjusted to the functional circuit board 2, and the second screw is installed and fixed in the base of the casing 1, and the mains transfer socket 4 is fixed on the rear side wall of the casing 1 with screws and the power is introduced into the The wire and the power plug wire 3 are welded together on the corresponding soldering point reserved on the functional circuit board 2. After the welding is completed and the power-on inspection is correct, the upper cover of the casing 1 is fastened, and the charger finished product of the present utility model is made. With reference to Fig. 2 Fig. 3, the operating principle and usage method of the present utility model are described as follows: the mains plug of the power plug line 3 is inserted into the mains socket, the AD power conversion circuit on the functional circuit board 2 works, and the 220V mains is converted into The 5V low-voltage DC power supply is provided to the intelligent charging management chip to adjust and become a 4.2V charging voltage, which is sent to the USB charging socket 5, and then sent to the mobile phone charging socket through the charging plug connection 7 inserted into the USB charging socket 5 to charge the battery of the mobile phone. At this time, the charging status indicator light 6 is yellow, indicating that charging is in progress, and when the battery of the mobile phone is fully charged, the charging status indicator light 6 turns green, indicating that the charging is completed. the

Referring to Figure 3, when the number of users who need to charge at the same time exceeds the number of charging sockets connected to one charger, use the method shown in Figure 3 to insert the power plug line 3 of another charger of the same type into the first part The mains adapter socket 2 at the rear of the charger doubles the charging capacity, from the original one charger charging 3 mobile phones to 2 chargers charging 6 mobile phones at the same time, and so on , Use this method to charge more mobile phone users at the same time, which relieves the tense situation of charging difficulties caused by the lack of mains sockets in local environments, and facilitates cluster customers. the
