Lighting industry is just a new industry, the system product quality is not a comprehensive understanding of the study is not deep enough, often appear quality and safety incidents, although the LED waterproof connector for the variety and variety of plugs, but the quality of uneven The
The same time as
According to the product structure design, LED waterproof connector plug can be divided into plastic type, after the type of these two types.
　　
　

In addition, the number of PINs and cable lengths can not be changed. The end user must and the manufacturer can determine the parameters accurately before they can be produced. If the cable and the connector are finished before the factory, the package has the advantages of simple structure and low total cost. , Can not achieve the pre-production inventory; after the type of equipment that customers do not take any cable connector.

In the construction site through a simple tool in the field according to the needs of the project to cut the length of the cable, the cable into the connector, and then provide a nut at the end of the cable fixed and waterproof, such connector plug structure is relatively complex, Installation flexibility of the advantages of high, especially for on-site emergency, can achieve a large number of inventory production.
The same time as
When selecting a waterproof connector plug, it must first be based on technical requirements such as electrical, installation, connection, insulation, and protection. As the design and production of selected some of the actual standard is borrowed from other industries, the application of a long time, many standards can not meet the rapid changes in the LED industry requirements.
The same time as
So the selection in addition to look at the basic technical standards, but also to test the UL yellow card standards prevail, and the individual standard requirements are relatively low, resulting in a lot of family workshop production are standard static environment for the production requirements, combined with the laboratory Testing is based on standard terms and standards of environmental testing, so many accidents, according to technical standards found that the product is qualified, and the actual application environment is vastly different, should exceed the current production technology standards, pay attention to practical application encountered Case.
The same time as
Second, look at the structural principle of design, if the choice of structural principles design obsolete, even if the production process quality control is very good, reliability and outdoor long-term weather resistance and so on can not be more reliable than the new generation of products. And then look at the assembly of the tolerance size control accuracy, waterproof connector plug size requirements are very high, many product shape and structure are basically the same, in order to ensure the stability of the connection, the selection must be carefully measured with the caliper, the general good quality With the size does not change much, otherwise the size changes greatly.
