Five Aspects Of Plastic Cable Waterproof Connector Selection

Nowadays, there are many types of connectors, one of which has waterproof function, such as Nylon Cable Gland. How do we choose this type of connector in daily life? From the following five aspects, you can choose high-quality connectors with a high probability.

1. First of all, the selected connector should meet the requirements of industry technical standards, such as electrical, installation, connection, insulation and protection, which should be qualified. This is the basis for selecting connectors.

2. When choosing, you cannot be satisfied with the standard, but should see whether the production of the connector exceeds the standard, and pay attention to the actual application environment and conditions. Some standard clauses have relatively low requirements. In simple terms, the threshold requirements for quality are relatively low, which may lead to lax quality control in the production process of some small factories.

Some test standards require them to be tested in a "standard static environment", but after repeated testing, it is found that the performance of the connector meets the standard, but there is a lack of engineering accidents in the actual use process. This is because laboratory tests are strictly tested in accordance with standard clauses and standard environments, while the environment of the actual application site varies greatly.

3. Understand the structural principle design of the joint. The structural design is very important at the beginning, but many people often ignore the structural design when choosing. If the newer waterproof and connection principles are used in the design, the performance of the product will often be more reliable. However, if the old structural principle is selected, if the quality can be controlled during production, the joint performance is still relatively reliable, but it may not be as good as new products in terms of long-term outdoor weather resistance.

4. It is necessary to check the tolerance size of the assembly parts and try to choose joints with small tolerances. Since the joints are often used in outdoor water environments, the reliability, waterproofness and matching of the connection should all meet the standards, which places high precision requirements on the size of the joints.

When we choose, we can find that the high-end and low-end joints are basically too different in appearance and structure, and we often can't see where the high and low performance is. However, if we use a caliper to measure carefully, we will find that the matching size of the high-end and low-end joints varies greatly, so that in actual use, the connection stability and waterproof performance of the low-end joints cannot be guaranteed.

5. It is also necessary to understand the production quality control system of the joint manufacturer. Some larger manufacturers will provide test reports and get better test data, but when you go to the factory for on-site inspection, you may find that there is no inspection standard for raw materials, no inspection link for finished products, and no repair process for unqualified products, which all affect the overall quality of the connector.

In the long run, if the manufacturer has a good quality system control, the qualified rate of the connectors shipped can be ensured. Therefore, whether the manufacturer's production quality control system is perfect is also one of the criteria for measuring whether the manufacturer is reliable. In general, manufacturers with large production scales and complete technical testing equipment have better product quality control.

When selecting plastic cable waterproof connectors, it is necessary to pay attention to whether the specifications and models of the connectors match the actual use occasions. At the same time, it is also necessary to pay attention to whether the materials of some connectors are of high quality. In many cases, the materials selected for good quality connectors must not be bad.
