Features of waterproof industrial plug:Industrial plug is a commodity widely used in CEE connectors. Its practical function is to maintain the connection and moisture-proof effect of transmission lines, or to cooperate with other mechanical equipment to maintain switching power supply. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. IP54, that is, dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade 4: prevent splashing water from invading, and prevent splashing water from all directions from invading. Industrial plugs are suitable for industry, generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and industrial connectors.Ip44 and ip672 are the key waterproof grades of industrial plugs. ip44 is the first generation product series, and the new model specification is ip67. Ip44-grade goods are relatively easy to manufacture, and the production process is not required high because of the low waterproof level. Ip44 provides as follows:.In the horizontal specification, ""is a two-digit number, with the first digit indicating the water resistance to solids and the second digit indicating the water resistance to liquids. There are 7 grades of solid waterproofing, which are indicated by 0-6, and 9 grades of liquid waterproofing, which are indicated by 0-8. The actual results are as follows:IP level: briefly indicated/defined0: No safety protection/no professional safety protection.1:50 mm solid/body mass parts, such as hands (without safety protection, can't be touched consciously), pass through 50 mm solid directly.2. Prevent 12mm solid/finger or the like, the length of which does not exceed 80mm, and the straight passage of which exceeds 12mm solid.3: Resistant to 2.5 mm solid/straight or thinner than 2.5 mm special tools, cables, etc., through to 2.5 mm solid.4: Prevent 1.0mm solid state/T2 red copper rod with straight warp exceeding 1mm from drawing stranded strips, and solid state with straight warp exceeding 1 mm..5: Anti-pollution/do not prevent all dust from entering, but the feeding amount does not hinder the normal operation of the machinery and equipment.6: Dust-free/dust-free passage.The processing technology requirements of Ip44 power socket are relatively low, and the production is very easy to manufacture. Ip67 is different, the waterproof grade of ip67 must be reached, and the goods must adopt excellent moisture-proof treatment technology and design.1. Solid particles with a diameter of 50 mm or 50 mm cannot pass through the top of larger solid particles.2. The warp prevention is 12.5mm so that the top of larger solid particles or the warp prevention is 12.5 mm.3. The anti-warp is 2.5mm so that the top of larger solid particles or solid particles with 2.5mm warp are completely impermeable.4 The solid particles with a diameter of 1 mm or 1 mm are completely impermeable to water at the top of the larger block of solid particles.Dust safety protection: floating dust can not be completely avoided, but it is not easy to stop the normal operation of equipment and reduce the level of safety factor.
