The power socket is a waterproof plug, which can provide safe and reliable electrical and signal connection, and has excellent waterproof performance. It is widely used in led street lamps, led power supplies, lighthouses, cruise ships, industrial equipment, industrial plugs, industrial plugs, communication equipment, testing equipment, commercial equipment, etc. 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 rapid commutation device and smart braking device. Industrial plugs are suitable for industrial use, and are 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 together with industrial sockets and connectors. Embedded socket is embedded in an integrated communication cabinet, which provides DC basic power for communication and data equipment in the same cabinet. It has certain universality at the same time. At present, there are many brands and types of power outlets in the market. Generally, there are power outlets in family life, such as triangular plugs, which can be called sockets, but they are generally not waterproof. So how to judge whether a socket is waterproof? The waterproof judgment level is IP68, and the real power outlets should be used in industrial power outlets. Waterproof grade standard is the main standard for evaluating the waterproof performance of connectors. The waterproof performance of Cee connector mainly depends on the two digits xx after ipxx, the first digit x is 0 to 6, and the highest level is 6; The second digit is 0 to 8, and the highest level is 8. Therefore, the highest level waterproof cee connector is ip68. Sealing principle: up to 5 sealing rings and sealing rings are used for pre-sealing under pressure. This kind of seal will not lose the pre-tightening force when the connector is thermally expanded and contracted in cold, thus ensuring the waterproof effect for a long time, and water molecules cannot penetrate under ordinary pressure. The general requirements of domestic power outlets are all up to ip66. IP66 is to spray water violently from all directions without water, and soak in 1m water for one hour without water. Many people don't know that there are already 10 "fingerprint" outdoor waterproof and rainproof sockets at home, and the indoor waterproof spray box is used instead of the power socket. The waterproof spray box can only spray water, but can't get wet directly, and can't resist aging, which is unsafe. It also has an ultraviolet lamp with a service life of less than one year. The company's main products are industrial plugs, industrial plugs, power sockets, power sockets, etc. The north is also known as the foothills of Yandang Mountain, a national key scenic spot in Florida, with developed traffic.
