Description

A waterproof power adapter housing Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically to a waterproof power adapter housing. Background Technology

[0002] A power adapter is an electronic device used to convert alternating current (AC) from the power grid into direct current (DC) for electronic devices. It is widely used in various small electronic devices such as mobile phones, laptops, tablets, routers, and monitors. It consists of a casing, transformer, inductor, capacitor, and other components. Its core function is to provide a safe and stable power supply to the device through voltage transformation, rectification, filtering, and voltage regulation. After installation, the power adapter casing needs to be waterproofed to prevent water ingress and damage to the internal components.

[0003] A search revealed that patent application number 202420990432.0 discloses a waterproof power adapter housing, belonging to the field of power adapter technology. It addresses the problems of power adapters being inconvenient to disassemble and repair, and the USB port being prone to water ingress when not in use. The housing includes a detachable cover at its front end, two guide holes at the front end, multiple fixing grooves at the front end, two limiting posts corresponding to the guide holes fixedly connected to the rear end of the cover, multiple fixing bolts corresponding to the fixing grooves rotatably connected to the front end of the cover, a USB port installed at the rear end of the housing, and a waterproof mechanism corresponding to the USB port at the rear end of the housing.

[0004] Although the waterproof power adapter casing incorporates a waterproof mechanism—a rotating waterproof plate that covers the USB port when not in use, with a magnetic connection between the iron post and the magnetic slot to fix the plate in place and prevent water from entering the USB port and damaging the power adapter—repeated friction and pressure cause gradual wear at the contact interface between the waterproof plate and the casing. This wear widens the sealing gap between the waterproof plate and the casing, compromising the originally tight waterproof barrier. Once the gap exceeds a critical value, external moisture and liquids can seep into the device, reducing the protective performance of the waterproof plate and potentially causing serious problems such as short circuits in electronic components and corrosion of mechanical parts.

[0005] Therefore, we propose a waterproof power adapter housing. Summary of the Invention

[0006] In view of the shortcomings of the prior art, this utility model provides a waterproof power adapter housing, which solves the problem that repeated friction between the waterproof plate and the housing in the existing device will increase the gap between the waterproof plate and the housing, thereby reducing the waterproof effect of the waterproof plate.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a waterproof power adapter housing, comprising a cover and a hollow housing with an open front end, wherein the cover and the housing are detachably connected by bolts, and a plug is installed at the front end of the cover;

[0008] The back of the housing is provided with a connecting shell that communicates with its inner cavity. A USB port is provided on the side of the connecting shell away from the housing. A waterproof component is provided on the back of the housing.

[0009] The waterproof component includes a protective cover and an elastic sealing ring. The elastic sealing ring is movably fitted on the outer surface of the connecting shell, and the inner wall of the elastic sealing ring is fixedly fitted with elastic sealing rings distributed in a linear array.

[0010] Preferably, the specifications of the inner cavity of the protective cover match the specifications of the connecting shell, and an elastic element is fixedly installed on the top surface of the protective cover. The top end of the elastic element is fixedly installed on the back of the shell, wherein the elastic element facilitates the connection between the protective cover and the shell.

[0011] Preferably, the elastic element is a nylon spring sheet, and the cover, shell, connecting shell and protective cover are all made of PC material. The shell and connecting shell are integrally molded structures. Nylon material has the characteristics of wear resistance and fatigue resistance and can withstand repeated elastic deformation.

[0012] Preferably, a sealing gasket is adhered to the front end face of the housing. The sealing gasket is made of rubber. The sealing gasket fills the gap between the contact surfaces of the cover and the housing, thereby increasing the sealing performance between the cover and the housing.

[0013] This invention provides a waterproof power adapter housing. It offers the following advantages:

[0014] The housing of this waterproof power adapter uses a sealing gasket to fill the gap between the cover and the housing, preventing external dust and water from entering the interior of the housing through this gap. When not in use, the protective cover is placed over the outside of the connecting shell, thus blocking the USB port. An elastic sealing ring fills the gap between the connecting shell and the protective cover, preventing external dust and water from entering the USB port. This improves the waterproof and dustproof effect of the housing and connecting shell, and is beneficial for protecting the components inside the housing. It solves the problem that repeated friction between the waterproof plate and the housing in existing devices leads to an increase in the gap between the waterproof plate and the housing, resulting in a decrease in the waterproof effect of the waterproof plate.
