Description

Technical Field

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

[0002] A 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 housing, 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 bars, massagers and other equipment. The power adapter is also called an external power supply. It is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as mobile phones, LCD monitors and laptops.

[0003] The existing patent (Announcement No.: CN220107018 U) discloses that the edge of the power adapter body is protected by a rubber edge, which effectively prevents the edge of the power adapter body from being collided and avoids friction of the power adapter body. The dustproof piston can seal the power adapter charging cable interface to prevent dust from entering the interior of the power adapter charging cable interface and avoid poor contact of the power adapter charging cable interface.

[0004] However, the above technical solution still has certain defects. The power adapter body is protected by installing a rubber edge at the edge thereof. However, if the power adapter body falls from a table and is subjected to a large impact force, and the pins are simply connected via the pin covers, the pin covers will be separated from the pins when a collision occurs, thereby causing damage to the pins. Therefore, a power adapter with a dustproof jack is proposed. Utility Model Content
