The connecting terminal is an accessory product used to realize electrical connection, which is classified as a connector in the industry. If the terminals are not fixed properly, it is likely to cause accidents such as instantaneous power failure, poor contact, and even the product disintegration. Therefore, manufacturers have to carry out a series of inspections to prevent poor connector fixation.
1) Interchangeability check
Interchangeability inspection requires that the matching plugs and sockets of the same series can be mated and connected to each other, and it is found whether there is any failure to be inserted and positioned due to the out-of-dimension of insulators, contacts and other parts, missing parts or improper assembly And locking, and even cause disintegration and other consequences under the action of rotating force. To avoid major failure accidents.
2) Torque check
Torque inspection is a very effective inspection method to assess the reliability of the terminal structure. According to the standard, samples should be sampled and tested for torque resistance in each batch, and problems can be found in time
3) General test of crimped wire
According to the product technical conditions, the manufacturer must conduct a thorough test on all the mounting holes of the delivered plug (seat) sample before the finished product leaves the factory, that is, use the loading and unloading tool to simulate the crimped wire with the pin or jack into place. Check if it can be locked. This test requires a pull-off force check one by one. In order to avoid failures such as failure of the crimped wire to be delivered, or failure to lock after delivery, and unreliable contact.
Without reliable connection terminals, there is no reliable system engineering. TXGA supports a one-stop connection terminal customization service. You only need to provide the final application conditions, and you can customize research and development according to your needs to meet various complex application conditions.
