Design points of Zhongshan waterproof junction box

1. Selection of materials: The main application areas of the current waterproof junction box products are the worksites and open-air sites with relatively harsh environments. When considering the protection function of the product, the impact resistance, static load strength, insulation function, non-toxicity, anti-aging function, corrosion resistance function and flame retardant function of the material should be considered. (The non-toxic function has been widely valued, mainly because if the waterproof junction box product encounters a fire, it will not release toxic and harmful gases when incinerated. Generally, it is often killed by inhaling a lot of toxic gases when a fire occurs. Majority.

2. Structural design: The overall strength, beauty, easy processing, easy installation and recyclability of the waterproof junction box should be considered. Now the waterproof junction box products produced by mainstream manufacturers in the world do not contain any metal accessories, which can simplify the product recycling process. However, the materials selected by most domestic manufacturers are different now, and the materials have poor anti-waxing properties. Generally, brass inserts are installed in the device sockets in the waterproof junction box to increase the strength of the device, which will affect the data recovery process. Add time and cost. Such problems can be solved if the original materials with high functional indicators provided by regular manufacturers are used.

3. Wall thickness: Generally, when designing the product, considering the overall cost of the product, the wall thickness of the product should be reduced as much as possible while satisfying the impact resistance and anti-waxing function of the product. When designing the waterproof junction box in the world, ABS and PC The wall thickness of material products is generally between 2.5 and 3.5, the glass fiber reinforced polyester is generally between 5 and 6.5, and the wall thickness of die-cast aluminum materials is generally between 2.5 and 6. The material wall thickness should be designed to meet the installation requirements of most components and accessories.

4. Selection of sealing rubber ring materials: For waterproof junction box products, commonly used sealing rubber ring materials are: PUR, EPDM, Neoprene, Silicon. Temperature range, tensile strength, expansion ratio, hardness, density, compression ratio, and chemical resistance should be considered when selecting a sealing ring.
