Nowadays, many waterproof joints and connectors of solar waterproof connectors on the market are waterproof. In daily life, we usually choose high-quality solar waterproof connectors from the following aspects:

1. Firstly, it is necessary to check whether the basic technical standards for connection, insulation, electrical, installation, protection, etc. are met.

2. Structural principle design, if the principles of waterproofing, connection, etc. are reasonable, is a qualified solar waterproof connector. Some outdated structural principle designs and quality control during the production and manufacturing process are good, but they are not as reliable as emerging products in terms of reliability and long-term outdoor weather resistance.

3. Beyond standards and focusing on practical applications, due to the low requirements of individual standard clauses, various waterproof connector factories produce them randomly. Some testing standards are tested in a "standard static environment", and it is still qualified to retest connectors after engineering accidents.

4. Control accuracy of tolerance dimensions for assembly parts. Generally, solar waterproof connectors involve connection, waterproofing, male female contact fit, etc. Therefore, there is a high requirement for precision in size. It is necessary to carefully measure the fit size of multiple pairs of connectors using professional calipers. Poor quality fit sizes vary greatly, which means that the stability of the connection is not guaranteed, and the consistency of batch products is poor.

5. The production quality control system of the connector factory. It is generally easy for connector manufacturers in Shenzhen to produce a pair of connectors for testing, and they can also obtain good test scores. However, in the factory, it can be seen that some raw materials do not have inspection standards, the finished products do not have necessary testing procedures before leaving the factory, and there is no procedure for repairing and testing unqualified products, all of which affect the overall quality of the product.

Therefore, a good quality system control is an important factor in choosing solar waterproof connectors, otherwise they may easily enter the pit. Overall, waterproof connector manufacturers with larger production scale and technical testing equipment will have a higher level of product quality control and stability.
