What Should Be Paid Attention To When Using Cold-pressed Terminals?

Cold-pressed terminals belong to the category of connectors. In the operation of electrical equipment, they are the link between wires and equipment. With the refinement and development of industrial control and electrical power, more and more cold-pressed terminals are installed on the equipment. , what should be paid attention to when using cold-pressed terminals?
1. You should fully understand the cold-pressed terminal to be operated and be familiar with its operation method to ensure correct operation; for cold-pressed terminals that do not have misoperation prevention, they should be marked with color codes or marks, or whether the appropriate model corresponds to , and ensure correct positioning when connecting to each other; special attention should be paid to prevent mis-mating of pin sockets, otherwise the cold-pressed terminals will be damaged and cause accidental electrical contact; the cold-pressed terminals should be connected in place, and in special occasions that are not easy to check, should Make detailed regulations in the corresponding operating procedures, and can be checked through the sight glass.
2. When the cold-pressed terminal is terminated, it should be terminated and inspected in strict accordance with the corresponding termination specifications or requirements, and terminated according to the corresponding node number. The maximum insulation layer thickness between the selected cable conductors should match the distance between the contacts, and the cable core should match the terminals of the contacts.
3. When soldering, the soldering iron with corresponding power should be selected according to the diameter of the bare wire. The soldering time of each contact should generally not exceed 5S. Care should be taken not to let the flux penetrate into the insulator, so as not to cause a decrease in the insulation resistance of the product.
4. Protective caps or other dust-proof measures should be installed on the cold-pressed terminals in a separated state; if the cold-pressed terminals are not separated for a long time after connection, insurance can be placed between the plug and the socket.
5. When cleaning the cold-pressed terminals, use a silk cloth dipped in anhydrous ethanol, and use it after drying. Chemical solvents such as acetone that may have a harmful effect on the connectors are not allowed.
6. When connecting or separating the cold-pressed terminals, try to make the axis lines of the plug and socket overlap as much as possible, and straighten the cable to prevent the plug from being subjected to tangential force and prevent the cable from sagging and causing damage to the connector.
7. It is forbidden to energize the cold-pressed terminal before it is connected correctly or completely locked.
8. In the case of fixing cold-pressed terminals and clamping wire harnesses, etc., there should be anti-loosening devices (anti-loosening screws, anti-loosening rings, fuses, etc.) when using threaded connections.
9. When checking and testing cold-pressed terminals, it should be carried out in accordance with the requirements of relevant product standards and instruction manuals. Acceptance and inspection of used electrical connectors should be carried out on the basis of relevant product standards and instruction manuals. The cold-pressed terminals used should be intact and have qualified performance; the probes should meet the standard requirements, otherwise it is easy to cause plugging hole damage.
Cold-pressed terminals, also known as "industrial rice", are ubiquitous in the field of electrical connections. Standardized use and frequent maintenance can greatly help the operation of electrical equipment; if the installation is not standardized, it may also cause Equipment short circuit, open circuit, there is a danger of damage to electrical equipment. The cold-pressed terminals in this article are also called wiring lugs and copper lugs. The product shapes are divided into O-shaped and U-shaped, and there are also differences between products with insulating sleeves and without insulating sleeves.
