Problems solved by technology

[0003] The following problems exist in the prior art. The original packaging method of the power supply is to design a qualified heat dissipation shell, and after the built-in drive circuit is integrally potted with glue for protection, after potting, it is sealed. performance, there is often a local void on one side of the cover that cannot be completely filled, resulting in long-term use. power failure
Furthermore, if the internal potting glue of the existing waterproof power supply uses epoxy resin and other glue with low hygroscopicity, it will easily cause residual stress failure of electronic components because of its hardness after curing; Larger, there is still a risk of moisture resistance for electronic components after a long time
Most of the current waterproof power supply can only be waterproof, and the moisture-proof effect is not good

Embodiment 3

[0043] A packaging method for a lightweight waterproof and moisture-proof power supply structure, comprising the following steps:

[0044] Insert the circuit board into the box body and fix it, install the wires, and seal the gap between the wires and the through holes;

[0045] The glue is poured into the box body from the top to cover the circuit board in the way of horizontal glue filling; the glue filling position is higher than the position of the through hole to ensure the complete sealing of the through hole; and it is lower than the respirator in the sealing cover The installation position on the top or on the side of the box body to ensure the space reserved inside the box body, and the internal and external air circulation can be realized through the respirator.

[0046] Assemble the sealing cover, the sealing cover and the box body are sealed and connected, that is, the screws are locked under the premise that the surrounding waterproof gaskets are accurately positi...

Abstract

The invention relates to the technical field of a power adaptor, in particular to a light, waterproof and dampproof power structure and a package method thereof. The light, waterproof and dampproof power structure comprises a sealing box body, an electronic component and a breather, wherein the electronic component is embedded into the sealing box body, and the breather is arranged on the sealingbox body. By arranging the breather on the box body, the indoor and outdoor pressure difference of a power cavity can be reduced by the breather, the internal environment is more stable, an effect ofwater prevention and ventilation can be effectively achieved by a waterproof and ventilation film in the breather, and various problems caused by damp of glue are reduced; and moreover, the box body has sealing performance by application of the box body and a sealing cover in a matching way, and water or air is enabled not to flow from other places of the box body.

Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to a lightweight waterproof and moisture-proof power supply structure and packaging method. Background technique [0002] Power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC Output; According to the connection method, it can be divided into wall-plug type and desktop type. It is widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment. [0003] The following problems exist in the prior art. The original packaging method of the power supply is to design a qualified heat dissipation shell, and after the built-in drive circuit is integrally potted with glue for protection, after potting, it is sealed. ...
