Issues To Consider When Designing Waterproof Junction Boxes

1. Material selection: The main application areas of weatherproof outlet box products are relatively harsh working sites and open-air sites. When considering the safety performance of waterproof outdoor electrical box, the impact resistance, static load strength, insulation performance, *non-toxicity*, anti-aging performance, corrosion resistance, and flame retardancy of the material should be considered. (Non-toxicity has received widespread attention, mainly because if ip68 junction box products encounter fire, they will not release toxic and harmful gases when burning. Generally, most people die from inhaling a large amount of toxic gases when a fire breaks out.

2. Structural design: The overall strength, beauty, easy processing, easy installation and recyclability of waterproof outdoor electrical junction box should be considered. At present, the weatherproof outdoor socket box products produced by international mainstream manufacturers do not contain any metal accessories, which can simplify the recycling process of the products. However, most domestic manufacturers now use different materials from waterproof connection box, and the material has poor anti-glutinous deformation performance. Generally, brass inserts are installed in the installation sockets in waterproof plug box to increase the installation strength, which will increase the time and cost of the material recycling process. If you choose raw materials with high performance indicators provided by regular manufacturers, you can solve this problem. 3. Wall thickness: Generally, when designing water tight electrical box products, the overall cost of the product should be considered, and the product wall thickness should be reduced as much as possible while meeting the product's impact resistance and anti-wax deformation performance. When designing international waterproof cable box, the wall thickness of ABS and PC materials is generally between 2.5 and 3.5, 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 wall thickness of the material should meet the installation requirements of most components and accessories during design. 4. Selection of sealing rubber ring materials: For plastic weatherproof electrical box products, the commonly used sealing rubber ring materials are: PUR, EPDM, Neoprene, Silicon. When selecting sealing rubber rings, the temperature range, tensile strength, expansion rate, hardness, density, compression rate, and chemical resistance should be considered.
