In the typhoon approaching, the rain increased, then the outdoor led display need to pay attention to waterproofing, enhanced waterproof protection can extend the life of the display, so waterproof protection from the source to check. Which waterproof connector selection is particularly important, the current market, more varieties of waterproof connectors, but the quality of uneven, then how to choose it?
Choose a good led display manufacturers, choose a high-quality LED waterproof connector, generally from the following aspects to consider.
First, first meet the relevant electrical, installation, connection, insulation, protection and other technical standards, which is the basis of choice.
Second, look at the tolerance of the assembly size control accuracy.
Because the connector is often related to the connection, waterproof, male and female contact with the need for the size of a very high precision requirements, high-end and low-end connector ye look almost shape, structure, etc. are not as high and low, but How do you spend some time, with a caliper to measure more than the size of the connector with the connector will find that the quality of poor with a large change in size, that is, the stability of the connection is not guaranteed, batch product consistency is poor.
Third, led display manufacturers can not just look at the standard, should go beyond the standard, pay attention to the actual application of the situation encountered.
Because the LED industry connector design and production of some of the standards used in practice is borrowed from other industries, because the industry application time is relatively short, many terms do not meet and meet the rapid changes in the LED industry requirements, such as anti-aging materials Assessment, but generally speaking, in line with the use of outdoor engineering, but how to define, is to see UL yellow card or test subject, outdoor project life is based on the project manufacturer's business contract or a can be recognized as a "technical use Life expectancy ", which directly affect the product selection and design materials, but also led to a variety of reasons for the connector connector material.
In addition, the requirements of individual standard terms is still relatively low, that is the quality of the threshold is very low, resulting in a variety of family workshops can be free to produce, some test standards are in the "standard static environment" under the test, often appear After the accident, to re-test the connector found according to the standard or qualified, why, because the laboratory tests have chosen the standard terms and standard environment, and the application of the environment vary widely, such as the connector tail M16 cable fixed head Cable gripping force and anti-torque requirements, the standard said that the tensile strength of 80N, anti-torque value greater than 0.45Nm However, the actual use of the connector may exist artificially pulled and twisted, so that the actual data may be far about standard values, And this force is maintained between the two connectors for a long time, after a long period of outdoor use, often resulting in the connector is not waterproof or poor contact and open circuit.
Fourth, led display manufacturers focus on structural design, structural design is very important.
If the waterproof, the connection and other principles of the design is more advanced, it has been one by one, if the choice of outdated structural principle design, even in the manufacturing process of good quality control, but often in the reliability of outdoor long-term weather Sex and other aspects are not as innovative products more reliable.
Five, see led display manufacturers connector production quality control system.
Connector companies do a good job with a pair of connectors to provide testing is easy, you can also get a good test scores, but to the factory you will find that there is no test of raw materials, finished products without the necessary test links, defective product repair and testing No procedures, etc., have affected the quality of the product package, that is only done 100% qualified, did not do thousands of thousandths, million of qualified. In the long run, good quality control system and even the lighting manufacturers choose the most important reference factor manufacturers, otherwise it will "because of small loss." Overall, with a larger scale of production, technical testing equipment business, product quality control and stability corresponding to a higher grade.
Choose a good outdoor LED display, need to consider from all aspects, not only the quality of the product, but also according to the company's overall strength and quality system, after-sales service, and so these aspects to consider. With the product quality of enterprise life, from raw material procurement to production, installation, testing, every step in accordance with the ISO9001: 2008 international quality control process implementation, scientific management, excellence, products through a professional organization of UL, RoHS, CCC , CE, EMC, FCC, ETL, IP65 dust and water quality testing to ensure that every factory products are high-quality, the basic lead and to achieve in the industry LED product standardization, batch of high standards of production management system. In the domestic and foreign countries to win a good reputation in the industry have a far-reaching impact.
