The name of Cee connector is used for non-life connectors, that is, in the industrial environment, because there are many industries, each of which has a different use environment, compared with the very harsh environment, it is difficult for ordinary connectors to achieve the normal working connection goal, and it also updates the use of a new type of connector, which we collectively call cee connector. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. NEMA wiring device must be as small as possible in order to realize frequent commutation, but also to realize braking during commutation and acceleration after commutation. Therefore, it is necessary to adopt commutation device quickly and braking device effectively. Embedded socket is embedded in the integrated communication cabinet, which is a power supply device that provides basic DC power for communication and data equipment in the same cabinet. It also has certain versatility. Therefore, compared with the original connectors, cee connectors have different degrees of environmental protection besides quality advantages. Perhaps many people don't understand what the numbers on cee connectors represent, so please read on.Then we will often see the protection of a digital cee connector product, such as ip67 and ip68, and then our current level cee connector has reached ip67. Two of the numbers contain the meaning of dustproof level and waterproof level. All right, let's start with the dust level. Including the numbers 0-6,0 means that there is no protection for the influence of this connector, so 1 means that objects over 50 mm can be prevented from entering the interior of the connector, higher order and smaller object size, 2 means to prevent the intrusion of 12.5 mm objects, 3 means to prevent the intrusion of 2.5 mm objects, 4 means to prevent the intrusion of 1 mm objects, and 5 means the ability to bear certain objects without affecting the interior. The highest level of protection, the sixth level, completely protects the connector from objects of any size.The waterproof grades of CEE connectors include 8 kinds of 0-8, and the protection grade of 0 means that there is no protection effect at all. The protection level of 1 can prevent the vertically falling water droplets from entering the connector, and the level of 2 can prevent the vertically falling water droplets from causing harmful effects on the vertical surfaces of the housing when the housing is tilted to 15 degrees. Class 3 can prevent the connector from being drenched by water and water droplets from entering it. Level 4 can prevent splashing water on the shell from any direction without harmful effects. Level 5 can prevent water spraying from any direction to the housing without harmful effects. Level 6 can prevent strong water spray, and level 7 can be completely immersed in water, but the highest level of protection is currently used. Then users can refer to this value when purchasing CEE connectors to avoid unnecessary losses.
