The terminal serial - encyclopedic knowledge - Prevention of fixed bad

1) Compatibility check compatibility check is a dynamic inspection. It requires the same series matching plug and socket can be inserted with connection each other, to find whether there is due to the insulator, such as pieces of contact parts size out-of-tolerance, causes such as missing parts or assembly does not reach the designated position cannot be inserted, positioning and locking, even in the rotating force under the action of disintegration. Compatibility check role is another thread, bayonet plug connection can have an impact in the insulation performance of metal tailings. So for some important use of terminal blocks shall be 100% for the project inspection, to avoid this kind of major fatal failure accidents. 2) Resistance to torque check torque check is a terminal structural reliability is very effective inspection method. As the U. S. military standard MIL - L - 39012 standard. According to the standard samples of each batch of parking should be resistant torque checks, found the problem in time. 3) Pressure welding wire flux measurement in denso often find individual core wire pressure does not reach the designated position, or send in place after the lock, contact is not reliable. Analysis of the reason is that the individual mounting holes had dirt stuck burrs or teeth. Especially use factory has denso to a connector at the end of the several mounting holes, found that the defects after illness had to have installed other discharge hole pressure welding wire, to replace the connector. In addition, due to the lead wire diameter and aperture pressure to choose cooperate with improper, or because the crimping process error, will cause end not firm pressure to the accident. For this purpose, the factory in the plug of the finished product before delivery to the delivery of the goods ( A) Samples of all mounting holes to test, with loading and unloading tools will have pressure to pin the wires or jack simulation to send in place, check whether to lock up. According to the regulations of product technical conditions, by the root pressure welding wire for pulled off force tests. Without reliable terminals, there is no reliable systems engineering. Dongguan precision co. , LTD. , in terminal strict control on raw materials, materials used are imported or domestic high-quality materials. Mainly in copper, stainless steel materials are purchased from famous suppliers, effectively avoid the terminals in the raw material part material cause of failure. Failure and reliability is corresponding to the interconnected another two aspects of contradiction. Through the terminal reliability screening found various failure modes and failure mechanism, can lead to a lot of lessons and eliminate all kinds of hidden dangers, to improve the design, process, inspection and provide scientific evidence for use, it is also revise and formulate the important basis of terminal technology conditions. Looking for measures to prevent failure, transformed from failure to reliable, is the dongguan precision co. , LTD. Is the ultimate goal of failure analysis.
