What are the common failures of heavy-duty connectors?

　Heavy-duty connectors are also known as heavy-duty connectors, aviation plugs and so on, the product has been in rail transportation, textile machinery, construction machinery, hot runners and automated machinery to play an important role. In the use of the product, there are several common failures hope to cause the majority of users to pay attention to.　　First, the insertion of the pin back If there is a defective component, making the support is not reliable, such as the pin lack of shrapnel is likely to lead to poor pin guidance, usually in the female pin insertion and fitting end face left in the case of the male pin extrusion. In the crimping process, improper crimping, resulting in deformation or bending, so that the mounting holes interfere with each other, resulting in assembly is not in place, resulting in the phenomenon of pin withdrawal during insertion. In addition, if the wire is too thin or hole is too small will also cause improper insertion and integration problems.　　Second, bad contact Usually speaking effective contact distance, that is, the insertion of each pin in the surface of the height of the basic same, insertion, insertion force has increased significantly, if the insertion of each pin in the surface of the different heights, then there may be in the case of individual pins in poor contact. If the female pins do not hold the force will also have poor contact problems, we can test the holding force to determine one by one.　　Third, poor fixation Insulator can not only play the role of insulation, but also for the connector to provide the role of centering and positioning, so that it can be fastened in the equipment above, if the fixation is poor, then it will lead to unsuccessful connection, and may even lead to the disintegration of the product.　　Can be inserted when the pin back, bad contact and poor fixation is the use of heavy-duty connectors more common failures, I hope that after reading, we can be prepared for these failures, so that such failures can be dealt with in a timely manner.
