Application range of waterproof junction box
Waterproof junction boxes are commonly used in construction sites, mines, cabins, outdoor electrical, communication, fire safety company equipment, steelmaking, petroleum university chemical, electronics, electricity, railways, construction sites, mines, mines, airports, hotels , ships, innovation workshops of large logistics enterprises, coastal workshops, and unloading yards are the first important technical equipment, which is one of the reasons for the development of electrical control and electrical management system integrated wiring structure design research materials.
What are the advantages of plastic waterproof junction box?
1.Plastic has the advantages of waterproof junction box material: the main application range of plastic waterproof junction box is the family with more humid environment, and it is also suitable for production site environment and open space. Therefore, non-toxic, impact-resistant, high-static-load strength, erosion-resistant, and flame-retardant materials should be selected.
2.Plastic waterproof junction boxes can effectively protect certain electronic components and are usually made of plastic square boxes. The feature of this waterproof junction box is to protect these components from danger to the human body, so even when the electrical equipment is in use, leakage does not pose a threat. The plastic waterproof junction box has a strong overall teaching design, is very beautiful, easy to process and install, and is a craft product that accepts repeated practice. At present, the waterproof junction box products produced by international mainstream manufacturers in my country do not contain metal accessories, which simplifies the product acceptance process. The top cover of the junction box is threaded for easy installation. The sealing ring is made of high-quality silica gel, and generally adopts the design of double vise, which can form two vacuum chambers and form vacuum isolation. The utility model has the advantages of corrosion resistance, small size, light weight, long service life and low cost.
3.The plastic waterproof junction box is made of ABS plastic with insulating function, and the terminals are fixed in the plastic junction box. Not only does it protect the circuit, but it defines the response of all zeros, which can serve a great aesthetic purpose. That’s what a plastic junction box can do. It can not only be used in our family life, but also in some large public places, such as hotels, factories and so on. It can be seen that plastic junction boxes play an important role in our daily life.
Production process of waterproof junction box
1.Material selection: At present, waterproof junction box products are mainly used in industrial and outdoor occasions with relatively harsh environments. When considering the safety performance of the product, the impact resistance, static load strength, insulation performance, non-toxicity, aging resistance, erosion resistance, flame retardant, etc. of the material should be considered. Because the waterproof junction box product does not release toxic and harmful gases in case of fire, its non-toxic feature has received widespread attention. In the general environment, a large number of toxic gases decay and die, and inhalation of a large amount of toxic gases causes fires. A lot of toxic gas.
2.Organizational design: The overall strength of the waterproof junction box, beautiful appearance, easy processing, easy installation and reusable use should be considered. At present, the products produced by international liquor manufacturers of waterproof junction boxes do not contain metal accessories, which can simplify the process of product take-over, but most domestic manufacturers choose different materials, which have poor resistance to waxing. Increasing the installation strength will affect the cost of the material takeover process. Such problems can be solved by internal manufacturers by selecting and supplying raw materials with high performance indicators.
3.Wall thickness: Generally speaking, when designing a product, the comprehensive cost of the product should be considered as much as possible, so as to reduce the wall thickness of the product as much as possible while satisfying the impact resistance and welding resistance of the product. For waterproof junction boxes, the wall thickness of ABS and PC materials is generally 2.53.5, the glass fiber added polyester is generally 56.5, and the wall thickness of die-casting aluminum products is generally 2.56. The design of the material wall thickness should meet the installation requirements of some large parts.
4. Selection of sealing rubber ring material: For waterproof junction box products, the commonly used sealing rubber ring materials are PUR, EPDM, neoprene, and silicone. Temperature scale, tensile strength, expansion ratio, hardness, density, compression ratio and chemical resistance should be considered when selecting a sealant.
