How to select LED connectors?

In the south, the dry season is longer and the air is humid. Therefore, when choosing LED connectors, we will all consider the waterproof and moisture-proof functions of LED connectors. So how to choose a good LED waterproof connector? Which ways to start? We will introduce it in detail below. There are more and more varieties of LED waterproof connectors on the market now, but the quality is uneven. Therefore, when we hang LED waterproof connectors, we generally consider the following aspects: First, First of all, it meets the requirements of relevant electrical, device, connection, insulation, protection and other technical specifications, which is the basis for selection. Second, we should not only look at norms, but also go beyond norms and pay attention to the situation encountered in practical application.

-------------------------------------------------------------------------------------------------

Because some specifications selected for the planning and production of led industry connectors are borrowed from other industries in practice, because the application time of the industry is relatively short, many clauses do not meet and meet the rapidly changing requirements of the led industry. For example, the assessment of aging resistance data is only generally suitable for field engineering applications, but how to define it depends on the UL yellow card or the test, and whether the life of field engineering applications is based on the commercial contract of the project manufacturer or a "skill application life" that we can recognize. In addition, the requirements of a single specification clause are still relatively low, that is to say, the quality threshold is very low, which leads to the fact that all kinds of family workshops can produce at will. Some test specifications are tested in a "standardized static environment". After engineering accidents, it is often found that the connector is still qualified according to the specification. Why? Because the laboratory tests have selected the specification clauses and the specification environment, and the environment at the application site is very different. For example, the specification only says that the tensile force reaches 80N, and the torque resistance value is greater than 0.45 N.m. Third, look at the production quality control system of the connector factory. It is easy for a connector company to do a pair of connector supply tests, and you can get good test scores. However, when you arrive at the factory, you will find that there are no inspection specifications for raw materials, no necessary test links for finished products leaving the factory, and no procedures for correction and testing of unqualified products, etc., all of which affect the overall quality of the product, that is to say, it is only 100% qualified, but it is not qualified for thousandths or ten thousandths. In the long run, good quality system control is even the most important reference factor for lamp manufacturers to choose connector manufacturers, otherwise they will "lose big because of small things". Overall, companies with larger production scale and skilled testing equipment have a correspondingly higher level of product quality control and stability. Fourth, look at structural principle planning. Structural planning is very important. If the principle planning such as waterproofing and connection is relatively advanced, it will now be superior to others. If the planning based on expired structural principles is selected, even if the quality control in the production and manufacturing process is very good, it is often not as reliable as the products of the innovative generation in terms of reliability and long-term weather resistance in the field. Fifth, look at the tolerance scale control accuracy of the assembly. Because LED connectors often involve connection, waterproofing, male-female contact cooperation, etc., they need high precision requirements for scale. At first glance, high-end and low-end connectors are almost the same in shape and structure, but if you take a moment to carefully measure the cooperation scale of many pairs of connectors with a caliper, you will find that the cooperation scale of poor quality changes greatly, that is, the stability of connection is not guaranteed, and the consistency of batch products is poor.
