Reliability Inspection To Prevent Poor Contact Of Terminal
In order to ensure the reliability of the terminal quality and ensure good use effect, it is also necessary to carry out a series of effective preventive and reliable inspections in accordance with the standard technical requirements. First of all, attention should be paid to prevent poor contact of the terminals. So, how exactly should this goal be achieved? Generally speaking, users need to conduct continuity detection after installation. Especially for some key models of products, point-by-point conduction detection should be added.
The next step is to perform transient detection, because some of the current terminals are actually used under dynamic vibration conditions. Merely checking whether the static contact resistance is qualified, it does not guarantee reliable contact in a dynamic environment. This is because the connectors with qualified contact resistance often still experience instantaneous power failure during vibration, shock and other simulated environmental tests. Therefore, for some products with high reliability requirements, a dynamic vibration test should be performed on them to assess their contact reliability.
In addition, it also includes single-hole separation force detection. The so-called single-hole separation force actually refers to the separation force of the contact from the static state to the movement in the inserted state, which is used to indicate that the pin and the socket are in contact. Under normal circumstances, if the separation force of a single hole is too small, the terminal may cause signal transient interruption when subjected to vibration or shock load.
At the same time, it is necessary to pay attention to some inspections to prevent poor insulation of the wiring terminals. At this time, the insulation material needs to be checked. Everyone should know that the quality of its raw materials has a great influence on the insulation performance of the insulator. Therefore, it is extremely important for the selection of raw material manufacturers to reduce the cost and lose the quality of the material.
In addition, it is necessary to check the insulation resistance of the terminal insulator. For some process requirements, after assembling, electrical performance needs to be tested. Under normal circumstances, a reasonable process should be process screening in the state of insulator parts to ensure that the electrical performance is qualified.
