As we all know, heavy-duty connectors are used to cope with the harshest industrial scenarios. Because it can withstand harsh environments, it is widely loved by everyone, and it is widely used in construction machinery, robots, rail transit, power automation and other industries. In today's article, I will take you to understand the relevant knowledge of overloaded connectors.
1. The environment used by the overloaded connector
1. High temperature environment
First of all, in a high temperature environment, basically all equipment and components are a requirement that needs to be strictly controlled. How to maintain efficient operation in a high temperature environment. So what is the use of heavy-duty connectors in high temperature environments?
The metal material and insulating material of the heavy-duty connector determine the working ambient temperature of the connector. High temperature will damage the edge material, causing the insulation resistance and withstand voltage performance to decrease. For metals, high temperature can make the contact pair lose elasticity, accelerate oxidation and cause coating deterioration.
2. Wet environment
Secondly, in a humid environment, electrical equipment with heavy-duty connectors may cause an electrical breakdown accident. The humid environment causes the absorption and diffusion of water vapor on the surface of the insulator, which is easy to reduce the insulation resistance, and is in a high-humidity environment for a long time. , will cause physical deformation, decomposition, escaping products to produce breathing effect and electrolysis, corrosion and cracks, which is the biggest damage to heavy-duty connectors.
Therefore, in the high temperature and humid environment, how to strictly control the heavy-duty connectors is a guarantee for us to make the quality better and better.
When the heavy-duty connector is engaged with the connector, in order to make the connection more tightly, it needs to be designed to be firmly engaged, which means that the strength of the engagement is relatively large.
Therefore, the interaction of the forces of insertion and extraction can easily cause wear on heavy-duty connectors. So if you want to reduce wear and tear of heavy-duty connectors, you can look at the following good methods: The strength of the gold-plated layer on the contact surface can be increased, which can effectively reduce friction. The contact surface can be nickel plated first and then gold plated, which results in a little less friction than direct gold plating on copper.
2. How to reduce wear and tear of heavy-duty connectors?
At the same time, the thicker the nickel layer, the better the wear resistance of the gold-plated layer, the smoother the surface, the smaller the friction, and the smaller the wear.
