Tips: How to Prevent Failure of Teminal Block?

The plastic insulation materials and conductive parts of terminals are directly related to the quality of terminals, which determine the insulation and conductive properties of terminals respectively. Any terminal failure will lead to the failure of the whole system engineering. Prevention is the purpose and analysis is the basis.

1. Prevention of poor contact.
1) Conduction detection.
2) Instantaneous break detection.
Some terminals are used in dynamic vibration environment. The experiment proves that the static contact resistance can't guarantee the contact reliability in dynamic environment. Because, often contact resistance qualified connector in vibration, shock and other simulated environmental tests still appear instantaneous power failure phenomenon.
2. Prevent poor insulation.
1) Inspection of insulating materials.
The quality of raw materials has a great influence on the insulation performance of insulators. Therefore, the choice of raw material manufacturers is particularly important. We should not blindly reduce the cost and lose the quality of materials. We should choose the materials of large factories with good reputation.
2) Inspection of insulation resistance of insulator.
3. Prevention of poor fixation
1) Interchangeability check.
Interchangeability check is a dynamic check. It requires that the same series of matching plugs and sockets can be connected with each other, from which we can find out whether it is impossible to insert, locate and lock, or even disintegrate under the action of rotating force due to the size of insulators, contacts and other parts being out of tolerance, missing parts or not being assembled in place.
2) Torque test.
3) General measurement of crimping wire.
