Connectors are used to place wires, cables and connecting devices. They have a large output, and are more durable and reliable, especially in some outdoor industrial environments. A socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. 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. 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. It is widely used in industrial appliances and led lighting display equipment. It is more used indoors, and now because of its waterproof and dustproof advantages, it is rising linearly when used outdoors.In the application selection of led display screen, the connector should not only meet the functional requirements, but also have the characteristics of high temperature resistance and waterproof. There are many factors to consider when choosing a cee connector, so let's look at some key points of choosing a cee connector that can be used on led display screen.I. BrandBecause LED display screens are often used outdoors, they are often exposed to direct sunlight and rain when installed outside buildings. If the overall performance of CEE connectors is not enough to withstand this environment, it will lead to power failure and short circuit.Therefore, when choosing cee connectors, it is important to determine the brand of cee connectors. The most important consideration in purchasing cee connectors is quality. Brand is the first guarantee of quality. Only waterproof connectors can guarantee stable performance when used outdoors. People who use brand names believe in products, which means that cee connector manufacturers have reliable equipment quality. It's best to consult relevant professionals for brand recommendation, and don't trust brand recommendation on Baidu.Second, the structure principleThe design of Cee connector determines its reliability. Although the connector may be used smoothly, the internal structure may not meet the high standard, so it is necessary to check whether the factory's construction schematic meets the international and national standards. After inspection, check whether the factory connector is consistent with that described in the schematic diagram.Third, the protection levelCee connectors are evaluated according to the waterproof level. Each connector is waterproof and dustproof, but the level is different. Some led display screens should be placed outdoors, which may be affected by thunderstorms. Therefore, it is best to choose the location of protection level. For example, the highest protection level ip68 can completely prevent dust from entering, and it can be soaked under certain pressure.Fourth, control accuracyThe connector is smooth and waterproof, which requires a high level of precision. You can't tell good from bad by the appearance of cee connector. In practice, through negotiations with manufacturers, we first try to use cee connectors, and check whether there is any problem with its control capability, and there is no serious low-level control problem, such as leakage and tightening. In actual use, we can also see whether there is any deviation in its operation function and performance.V. MaterialThe Led display connector must be made of high-quality materials, such as imported copper. Check the joint, structure and shell of the connector to see if there is any problem of cutting corners.
