M12 A Code male Straight Head Waterproof Connector

There are places where the air is also more humid, so in the choice of LED connectors we will consider the waterproof, moisture-proof performance of LED connectors, so how to choose a good waterproof LED connector it? Where to start first? We will introduce you in detail, the current market LED waterproof Circular Connector more and more types, but the quality varies, so we are hanging LED Waterproof Connector, generally from the following aspects to consider.

First of all, to meet the relevant electrical, installation, connection, insulation and protection and other technical standards, these are the basis for the selection of materials.

Secondly, we should not just look at the standards, but go beyond them and focus on the problems encountered in practical applications.

As the LED industry in the design and production of round waterproof connectors selected in some standards are actually borrowed from other industries, due to the industry application time is relatively short, many provisions can not meet and meet the requirements of the rapid development of the LED industry, such as the inspection of aging-resistant materials, only in general terms to meet the use of outdoor projects, but how to define, is to see the UL mark or to test, outdoor projects The use of life is subject to the project manufacturer's commercial contract or to the generally accepted "technical life" shall prevail, these are directly affected by the selection and design of product materials, but also lead to a wide range of LED connector materials.

In addition, the requirements of individual standard conditions are also low, that is, the quality threshold is low, resulting in a variety of family workshops can be arbitrarily produced, some standard conditions are in the "standard static environment" under the test, often after an engineering accident, to retest the waterproof connector Waterproof Plug is according to the standard or standard test, why, because the laboratory test are selected standard conditions and standard environment, the application site environment varies, for example, the connector tail cable fixing head on the cable grip and resistance to torque requirements, the standard only says that the resistance to torque up to 60N, resistance to torque values greater than 0.3N.m, but the actual use of the connector may be artificially strong pull around the phenomenon, so the actual data may be far beyond the standard value, and this force in the outdoor for a long time After use, often lead to connectors are not waterproof or poor contact and breakage.

Third, look at the connector manufacturer's production quality management system.

Connector companies do a good job on a pair of connectors to provide testing is easy, but also to get a good test score, but to the factory you will find that raw materials without inspection standards, finished products factory without the necessary test links, the repair of non-conforming products and inspection without procedures, etc., will affect the quality of the entire product, that is, only to reach 100% of the qualified, not to reach the thousands of qualified. In the long run, a good quality system control is even the most important reference factor for lamp manufacturers to choose a connector manufacturer, otherwise they will "lose a lot because of the small". In general, the enterprise production scale, technical testing equipment, product quality control and stability of the corresponding higher grade.

Fourth, look at the structural principle design, structural design is the key.

Such as waterproofing, seams and other principle design is more advanced, has been a major trend; if the use of obsolete structural principle design, even if the manufacturing process quality control is good, but in the reliability, outdoor long-term weather resistance and other aspects are often less reliable than the new generation of products.

Fifth, look at the tolerance size accuracy of the decorative parts.

As connectors are often involved in connection, waterproofing, jointing, etc., the need for high precision requirements for size, connectors in high-grade and low-end how to see are similar, structure and other aspects are not more than high and low, but how to spend some time, using calipers to carefully measure more than one pair of connectors to join the size will find that the poor quality of the connector with a large change in size, that is, the stability of the connection is not guaranteed, batch Poor consistency.
