JH-C's structural engineering has rich experience in waterproof component application, electronic waterproof box, GPS positioning waterproof boxes packaging and waterproof boxes in the design of electronic products. Installation Box of Humidity Temperature Sensor

Before designing waterproof box waterproof box, it is necessary to determine the use environment of the product.

1. Products are used indoors or in wet splashing environment of warehouse

2. Products are used in outdoor rainwater environment

3 Products are used in shallow or deep water environments

These application environments need to be eradicated to determine the waterproof grade, so as to achieve the purpose of use, but also to save costs. The general waterproof grade is between IP63 and IP68. It is divided into image. png

IP63: Water or rainwater from 60 degrees corner to the shell has no effect;

IP64: The liquid poured from any direction to the shell has no damage effect;

IP65: Rinse with water without any harm.

IP66: Can be used in cabin environment;

IP67: It can withstand immersion (1m) in a short time.

IP68: immerse water for a long time under certain pressure, such as deep water cable connection.

For example, on the right is a waterproof box in the open air, which contains circuit boards, batteries and sensors with electronic components. Therefore, its waterproof level needs to reach IP67.

Design of Fixed Support for Waterproof Box

The waterproof box needs to be fixed on a circular column, and an open circular metal lock ring needs to be designed to connect the waterproof box to the column. In order to form a solid connection between the metal lock ring and the waterproof box, our design engineers have made some professional designs. They have made some matching groove designs on the waterproof box and the metal ring respectively. The metal nut is built into the box body, and the embedded nut forming process is adopted to make the nut and the box body become one body without loosening. Metal nuts don't slide easily. After connecting the metal ring with the box body, the metal ring is locked on the box body with a screw, so that the screw mainly bears the force in the horizontal direction and the force in the vertical direction will be borne by the matching concave-convex structure.

Design of internal structure of waterproof box

Batteries, PCBs and sensors need to be installed inside the waterproof box. Therefore, it is necessary to design the internal structure according to the actual size of these components.

Waterproof cover design

1. Fastening method of waterproof cover and waterproof box

The screw and embedded nut are used for connection and fastening.

2. Selection of Waterproof Structure

First of all, we need to understand the following common waterproof design methods.

Waterproof design of sealing mode, waterproof design of waterproof ring mode, waterproof design of ultrasonic mode, waterproof design of secondary beer-plastic mode and waterproof design of circuit sealing and insulation mode.

In the waterproofing design of electronic products, the waterproofing grade that electronic products need to reach must be clear. The structural design method adopted varies according to the waterproof grade. For example, the waterproofing design of secondary beer plastic can reach IP8, while the waterproofing design of stop mode can only reach IP4.
