What factors will affect the performance of RJ45 connectors? The following are some factors that affect the rj45 connector, you can understand: factors such as insulation material, temperature, humidity, contamination, test voltage and the duration of continuous application of the test voltage. The following are the detailed knowledge points:

Rj45 connector insulation material

It is very important to choose the insulating material when designing the electrical rj45 connector, which often affects whether the insulation resistance of the subsequent products can be stable and qualified. For example, a factory originally used materials such as acetaldehyde glass fiber plastic and reinforced nylon to make insulators. These materials contain polar genes and have high hygroscopicity. The insulation performance can meet the product requirements at room temperature, but the insulation performance is unqualified at high temperature and humidity. After the special engineering plastic PES (polyphenylene ether sulfone) material was used, the product was subjected to 1000h and 240h humidity tests at 200°C, and the insulation resistance changed little, still above 105MΩ, and there was no abnormal change.

Rj45 connector temperature

High temperature will destroy the insulating material, causing the insulation resistance and withstand voltage performance to decrease. For the metal shell, high temperature can make the contact part lose its elasticity, accelerate the oxidation and cause the deterioration of the coating. For example, the environment-resistant quick separation electrical connector series 2 products produced according to GJB598, the insulation resistance should not be less than 5000MΩ at 25°C, and it should be reduced to not less than 500MΩ at high temperature of 200°C.

Rj45 connector humidity

The humid environment causes the absorption and diffusion of water vapor on the surface of the insulator, which easily reduces the insulation resistance to below the MΩ level. Long-term exposure to high temperature environment will cause physical deformation, decomposition, and escape of insulators, resulting in breathing effect, electrolytic corrosion and cracks.
