How is the waterproof between the waterproof junction box and the conduit done?

1.Material selection: 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 safety performance of the product, the impact resistance, static load strength, insulation performance, non-toxicity, anti-aging performance, corrosion resistance and flame retardant performance of the material should be considered.

2.Structural design: the overall strength, aesthetics, easy processing, easy installation and recyclability of the waterproof junction box should be considered. At present, the waterproof junction box products produced by international mainstream manufacturers do not contain any metal accessories, which can simplify the product recycling process.

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 meeting the impact resistance and anti-waxy change performance of the product. When designing the international waterproof junction box, ABS and PC The wall thickness of material products is generally between 2.5-3.5, the glass fiber reinforced polyester is generally between 5-6.5, and the wall thickness of die-cast aluminum products is generally between 2.5-6. The wall thickness of the material should meet the installation requirements of most components and accessories in the design.

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