In some places, the air is relatively humid, so when choosing an LED connector, everyone will consider the waterproof and moisture-proof functions of the LED connector. So how to choose a good LED waterproof connector? Where do you start? At present, there are more and more types of LED waterproof connectors on the market, but the quality is uneven, so when we suspend the LED waterproof connectors, we generally consider the following aspects:
First, first meet the requirements of relevant electrical, installation, connection, insulation, protection and other technical standards, which is the basis for selection.
Second, we should not just look at the standards, we should go beyond the standards and pay attention to the situations encountered in practical applications.
Because some of the standards selected for the design and production of the LED industry connector are actually borrowed from other industries, because the industry has a relatively short application time, many terms do not meet and meet the rapidly changing requirements of the LED industry, such as the use of aging resistance materials. The assessment is just a general statement that conforms to the use of outdoor projects, but how to define it is based on the UL yellow card or the test. The life of the outdoor project is based on the commercial contract of the project manufacturer or a "technical use that everyone can recognize "Life is subject", these directly affect the selection and design of product materials, and are also the reason for the variety of led connector materials.
In addition, the requirements of individual standard clauses are still relatively low, that is to say, the quality threshold is very low, which results in a variety of home workshops that can be produced at will. Some test standards are tested in a "standard static environment" and often appear After the engineering accident, I went to retest the connector and found that it was qualified according to the standard. Why? Because the laboratory tests have selected standard terms and standard environment, and the environment of the application site is very different, such as the cable fixing head at the end of the connector grasping the cable tightly. The requirements of force and torque resistance, the standard only says that the tensile force reaches 60N, the torque resistance value is greater than 0.3Nm, but the connector may be pulled and twisted artificially in actual use, so the actual data may be far closer to the standard value, and this This force is maintained between the two connectors for a long time. After a long time of outdoor use, the connector is not waterproof or has poor contact and will be broken.
Third, look at the production quality control system of the connector manufacturer.
It is easy for a connector company to provide a pair of connectors for testing, and you can get good test scores, but when you arrive at the factory, you will find that the raw materials have no inspection standards, and the finished products do not have the necessary test links when they leave the factory. The absence of procedures and so on affects the overall quality of the product, which means that it is only 100% qualified, but not thousands or tens of thousands. In the long run, a good quality system control is even the most important reference factor for lighting manufacturers to choose connector manufacturers, otherwise they will lose big because of small mistakes. Generally speaking, for companies with larger production scale and technical testing equipment, product quality control and stability are correspondingly higher.
Fourth, looking at the design of structural principles, structural design is very important.
If the principle design of waterproofing, connection, etc. is relatively advanced, it will be better. If you choose the outdated structural principle design, even if the quality control in the manufacturing process is very good, it is often reliable and long-term outdoor weather resistance. Sex and other aspects are not as reliable as innovative products.
Fifth, look at the tolerance size control accuracy of the assembly parts.
Because connectors often involve connection, waterproofing, and male-female contact matching, etc., they need to have high precision requirements for size. At first glance, high-end and low-end connectors are almost the same in appearance and structure. If you take the time to carefully measure the mating dimensions of multiple pairs of connectors with a caliper, you will find that the mating dimensions of poor quality vary greatly, that is, the stability of the connection is not guaranteed, and the consistency of batches of products is poor.
