Description

Technical Field

[0001] The utility model relates to the field of power adapters, in particular to a wire protection device for a power adapter. Background Art

[0002] 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, routers, light strips, massagers and other equipment.

[0003] The existing power adapter cannot protect the power cord, especially the wire after use. Since the wire is generally long, the random placement of the wire can easily cause the outside to pull the wire and cause damage to the wire or the power adapter, thereby affecting the service life of the power adapter. Therefore, a wire protection device for a power adapter is proposed to solve the above problem. Utility Model Content
