Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with a pin switching function. Background Art

[0002] In the process of using the power adapter, the power adapter is widely used to transform the power supply. The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output. It can be divided into wall-mounted and desktop types according to the connection method. It is widely used in security cameras, set-top boxes, and router equipment. The power adapter is also used in the process of using the power adapter.

[0003] After searching, the existing Chinese patent announcement number is: CN219917690U, which provides a power adapter. When the distance between the power supply and the electronic device is short, the pin assembly is connected to the power supply, so that the space occupied by the redundant wires can be reduced. When the distance between the power supply and the electronic device is long, the input wire is inserted into the input interface to be electrically connected to the input interface, and then the input wire is connected to the power supply, so that the connection distance between the power supply and the electronic device can be extended to achieve the long-distance movement and operation of the electronic device. When the distance between the electronic device and the power supply is close, the space occupied by the power adapter connection wire is reduced, and charging can also be achieved when the distance between the electronic device and the power supply is far.
