Harness processing in the use of terminals need to pay attention to what problems?

In the daily work of wiring harness processing, we often use the terminals. Terminals are accessory products used to realize electrical connections, belonging to industrial connectors. From the point of view of use, the terminal should achieve the function is: the contact part must be reliable contact. Then in the wiring harness processing in the use of terminals need to pay attention to what problems?

First, to prevent poor contact 1, conductivity test: general terminal manufacturer's product acceptance test does not have this item, the user generally need to be installed after the conductivity test. However, we have 100% continuity testing of the wiring harness products of the terminals to ensure that the user's good performance. 2, instantaneous disconnection test: some terminals are used in dynamic vibration environment. Experiments have shown that only check whether the static contact resistance is qualified does not guarantee the reliability of the contact in a dynamic environment. Usually, in vibration and shock and other simulated environmental testing, contact resistance qualified connectors will still be immediately disconnected. Second, to prevent poor insulation insulation material inspection: the raw material is good or bad on the insulator's insulation performance has a great impact. Therefore, the choice of raw material manufacturers is particularly important, can not blindly reduce costs, loss of material quality. Should choose a good reputation of the big factory material. And carefully check the inspection lot number of each batch of material, material certificates and other important information, to do a good job of material use of traceability data. Third, to prevent poor fixing 1, interchangeability check: interchangeability check is a dynamic check. Requirements for the same series of matching plugs and sockets can be connected to each other, and to find out whether there is due to insulators, contacts and other parts of the size of the insulator, missing pieces or improper assembly caused by the insertion, positioning, locking and other faults, and so on, and even disintegrate under the action of the rotational force. 2, crimping general test: in the process of electrical installation, it is often found that the individual core crimping line is not delivered in place, or delivered after the inability to lock the contact is unreliable. The reason for this analysis is that there are burrs or dirt sticking to the screws and teeth of the individual mounting holes.
