Four major points in the design of waterproof junction boxes

1. Material selection: Currently, waterproof junction box products are mainly used in industrial and outdoor environments that are relatively harsh. When considering product safety performance, consideration should be given to material impact resistance, static load strength, insulation performance, non-toxic, aging resistance, corrosion resistance, flame retardancy, etc. Due to the fact that waterproof junction box products do not release toxic and harmful gases when exposed to fire, their non-toxic performance is receiving widespread attention. Generally, a large amount of toxic gases die, and inhalation of a large amount of toxic gases can cause a fire. There are many quantities of toxic gases.

2. Structural design: The overall strength, aesthetic appearance, easy processing, easy installation, and recyclability of the waterproof junction box should be considered. At present, the waterproof junction box products produced by international liquor manufacturers do not contain metal accessories, which can simplify the product recycling process. However, most domestic manufacturers choose different materials with poor wax resistance. Generally, brass inserts are installed at the installation sockets of waterproof junction boxes to increase installation strength, which can affect the material recycling process. Cost. This type of problem can be solved by selecting raw materials with high performance indicators provided by general manufacturers.

3. Wall thickness: Generally speaking, when designing a product, it is necessary to consider the overall cost of the product as much as possible, in order to minimize the wall thickness of the product while meeting its impact resistance and welding resistance. Product. The wall thickness of waterproof junction boxes, ABS, and PC materials is generally 2.53.5, glass fiber reinforced polyester is generally 56.5, and die cast aluminum products are generally 2.56. The design of material wall thickness should 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 include PUR, EPDM, chloroprene rubber, and silicone. When selecting sealing rubber rings, consideration should be given to temperature range, tensile strength, expansion ratio, hardness, density, compression ratio, and chemical resistance.
