Issues To Consider Before Practical Application Of Ukk Junction Box

Generally, the domestic distribution terminal block is 86-type. The so-called 86-type wire box refers to the outer diameter of the switch and socket panel is 86x86mm, the din rail power distribution open box is 86x86mm, the dark box is 75x75mm, and it is equipped with a din rail power distribution block cover (or directly equipped with a switch and socket panel), generally made of PVC and tin box.

1. Material selection: The main application areas of the current waterproof 4 pole distribution block products are relatively harsh industrial sites and open-air sites. When considering the product safety performance, 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-toxic performance has received widespread attention, mainly because if the waterproof 4 pole power distribution block product encounters a fire, it will not release toxic and harmful gases when burning. Generally, most people die due to 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 the waterproof din rail power distribution terminal blocks should be considered. At present, the waterproof power distribution block 4 pole 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, and the materials have poor anti-deformation performance. Generally, brass inserts are installed in the installation sockets of waterproof din distribution block 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 products, when considering the overall cost of the product, the product wall thickness should be reduced as much as possible while meeting the product's impact resistance and anti-deformation performance. When designing international waterproof electrical power distribution blocks, the wall thickness of ABS and PC material products is generally between 2.5~3.5, glass fiber reinforced polyester is generally between 5~6.5, and the wall thickness of die-cast aluminum material products is generally between 2.5~6. 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 waterproof power terminal blocks electrical products, commonly used sealing rubber ring materials are: PUR, EPDM, Neoprene, Silicon. When selecting sealing rubber rings, you should consider the temperature range, tensile strength, expansion rate, hardness, density, compression rate, and chemical resistance.
