- With the arrival of spring and summer, typhoon and rain increase significantly, so outdoor LED display screen needs to pay special attention to the waterproof problem. Strengthening waterproof protection can prolong the service life of display screen, so waterproof protection needs to be checked from the source. The selection of waterproof connectors is particularly important. At present, there are many varieties of waterproof connectors in the market, but the quality is uneven. So how to choose?
Choosing a good LED display manufacturer and a high-quality LED waterproof connector can generally be considered from the following aspects.
1、 First, meet the requirements of relevant electrical, installation, connection, insulation, protection and other technical standards, which is the basis of selection.
2、 See the tolerance and dimension control accuracy of assembly parts. Because connectors often involve connection, waterproof, male and female contact and matching, they need to have high precision requirements for size. At first glance, the shape and structure of high-end and low-end connectors are almost the same, but how can you spend some time and carefully measure the matching size of many pairs of connectors with a caliper, you will find that the matching size of poor quality changes greatly, that is, the stability of connection is not guaranteed, The consistency of batch products is poor.
3、 LED display manufacturers should not only look at the standard, but should surpass the standard and pay attention to the situation encountered in practical application.
Because some standards used in the design and production of connectors in the LED industry are actually borrowed from other industries. Because the application time of the industry is relatively short, many terms do not meet and meet the rapidly changing requirements of the LED industry. For example, the assessment of aging resistant materials is generally consistent with the use of outdoor engineering, but how to define it depends on the UL yellow card or the test, Whether the service life of outdoor works is subject to the commercial contract of the project manufacturer or a "technical service life" that can be recognized by everyone directly affects the selection and design of product materials, and it is also the reason for the variety of LED connector materials.
In addition, the requirements of individual standard terms are relatively low, that is to say, the quality threshold is very low, resulting in that various family workshops can produce at will. Some test standards are tested in the "standard static environment". After engineering accidents, it is often found that the connector is still qualified according to the standard. Why? Because the standard terms and standard environment are selected for laboratory tests, The environment of the application site varies greatly, such as the requirements of M16 cable fixing head at the tail of the connector for cable gripping force and anti torque. The standard only says that the anti tension reaches 80N and the anti torque value is greater than 0.45n M however, the connector may be pulled and twisted artificially in actual use, so the actual data may be far from the standard value, and this force is maintained between the two connectors for a long time. After long-term outdoor use, the connector is often open circuit due to non waterproof or poor contact.
4、 LED display manufacturers pay attention to the structural principle design, which is very important. If the principle design of waterproof and connection is more advanced, it will be better than others. If the outdated structural principle design is selected, even if the quality control in the production and manufacturing process is very good, it is often less reliable than the products of the innovative generation in terms of reliability and outdoor long-term weather resistance.
5、 Look at the production quality control system of LED display connector manufacturers. It is easy for the connector company to test a pair of connectors and get good test scores. However, when you arrive at the factory, you will find that there are no inspection standards for raw materials, no necessary test links for finished products, no procedures for repairing and testing unqualified products, etc., which affect the overall assembly quality of products, that is to say, only 100% qualified, not 1000% and 10000% qualified. In the long run, good quality system control is even the most important reference factor for lamp manufacturers to choose connector manufacturers, otherwise it will "lose big for small". Generally speaking, enterprises with large production scale and technical testing equipment have a higher level of product quality control and stability.
Choosing a good outdoor LED display needs to be considered from all aspects, not only the quality of the product, but also according to the company's comprehensive strength, quality system, after-sales service and so on. Shenzhen kangsenshi Technology Co., Ltd. is a professional and innovative LED display manufacturer, integrating R & D, production, sales and engineering services, which is worthy of your recognition. Welcome to inquire.
