Due to the uneven quality of LED waterproof connectors on the market, we need to consider factors such as waterproof grade when choosing LED waterproof connectors. Below, we will introduce how to choose a good LED waterproof connector.

1. InspectionLED waterproof connector manufacturerOur production quality control system. It is easy for a connector company to conduct a pair of connector supply tests and obtain excellent test scores. However, when you arrive at the factory, you will find that there are no inspection standards for the materials, no necessary testing procedures for the products leaving the factory, and no procedures for correcting and inspecting unqualified products, all of which affect the quality of the bundled products. That is to say, only 100% of the products are qualified, not 1000% or 10000% of the products are qualified.

2. Check the Aufbau principle planning. If the waterproof, connection and other principle planning are more advanced, they are now one upmanship. If the expired Aufbau principle planning is selected, even if the quality control in the production process is excellent, they are generally less reliable than the innovative generation of goods in terms of reliability, long-term outdoor weather resistance, etc.

3. Check the operational accuracy of the assembly at the official scale. Due to the fact that waterproof connectors usually involve connections, waterproofing, male female touch cooperation, etc., high precision requirements are required for the scale. At first glance, high-end and low-end connectors are almost identical in appearance, construction, and other aspects. However, if you take the time to carefully measure the cooperation scale of multiple connectors with a caliper, you will find that the cooperation scale of poor quality connectors changes greatly, which means that the stability of the connection is not guaranteed, Poor consistency of batch products.
