Pay attention to the crimping operation of the cold terminal
First of all, you need to fully understand the cold-pressed terminal to be used, and keep in mind its operation method to ensure correct operation. For cold-pressed terminals that do not have misoperation prevention, they should be identified by color code or mark, or whether the appropriate model corresponds before connection, and ensure that they are correctly positioned when they are connected to each other. At the same time, special attention needs to be paid to prevent the mis-plugging of the pin socket, so as to avoid damage to the terminal and cause accidental electrical contact.
Particular attention must be paid to ensure that the cold-pressed terminals are properly connected. If the work situation is special, detailed regulations must be made in the corresponding operating procedures and can be inspected through a speculum. When terminating, it should be terminated and inspected strictly in accordance with the corresponding termination specifications or requirements, and terminated according to the corresponding node number. Note that the thickness of the insulating layer between the cable conductors used should match the spacing of the contacts, and the cable core should match the terminal of the contact. When the contacts are spanned and paralleled.
In addition, if the cold-pressed terminal is in a separated state, appropriate dust-proof measures need to be taken. If it is not separated for a long time after connection, you can put a fuse between the plug and the socket. When cleaning the cold-pressed terminal, you can use a silk cloth dipped in absolute ethanol, and use it after drying. Chemical solvents such as acetone, which may have a harmful effect on the connector, are not allowed.
What needs to be reminded is that whether it is connection or separation, it is recommended to overlap the axis of the plug and the socket as much as possible, and to straighten the cable to avoid the plug being subjected to tangential force, and to prevent the cable from sagging and causing damage to the connector. It is forbidden to energize the cold-pressed terminal before it is properly connected or fully locked. In occasions such as fixing and clamping of wiring harnesses, there should be an anti-loosening device when using threaded connections.
In addition, acceptance and testing are required. During this process, you need to follow the relevant instructions. Generally, when accepting and inspecting used electrical connectors, it is necessary to reduce the requirements on the basis of the relevant product standards and instructions. The tooling cold-pressed terminals used should be intact and the performance should be qualified; the probe should meet the standard requirements, otherwise it is easy to cause Damage to the jack.
