The method of measuring the separation force of a single hole is more effective than measuring the contact resistance. Finding various failure modes and failure mechanisms through the reliability screening of terminal blocks can draw a lot of experience and lessons and eliminate various hidden dangers, and provide scientific basis for improving design, process, inspection and use. Prevention of poor contact 1)

Continuity test At present, the product acceptance test of general terminal manufacturers does not have this item, and users generally need to conduct continuity test after installation. Contact reliability. As a result, the insulation resistance of the insulator itself is unqualified, so the entire batch of finished products has to be scrapped. The experiment proves that it is only used to check whether the static contact resistance is qualified, and it cannot guarantee the reliable contact in a dynamic environment. Experiments show that if the separation force of a single hole is too small, it may cause instantaneous signal interruption when subjected to vibration and shock loads.

For this reason, in addition to researching and developing a new generation of flexible plug-in contact with stable and reliable contacts, the manufacturer should not use automatic plug-in force testing machines for multi-point simultaneous testing of key models, and should conduct 100% point-by-point orders for finished products. Another function of the interchangeability check is to detect in time whether there is any metal surplus that affects the insulation performance through plug connections such as threads and bayonets. According to the standard, samples should be sampled and tested for torque resistance in each batch to find problems in time. Please log in:

Therefore, it is recommended that manufacturers add 100% point-by-point conduction detection to some key models of products
