Points to note when crimping cold-press terminals?? First, it is necessary to have a thorough understanding of the cold-press terminals to be used and to remember their operating methods in order to ensure proper handling. For cold-press terminals that do not have error-prevention features, color codes or markings should be used for identification, or it should be checked before connection whether the appropriate model is being used, to ensure proper alignment when connecting them together. Special attention must also be paid to preventing the incorrect insertion of plug sockets with pins, in order to avoid damaging the terminals and causing accidental electrical contact. Special attention must be paid to ensuring that the cold-press terminals are properly connected. In cases where the working environment is particularly special, detailed provisions must be included in the relevant operating procedures, and inspections can be carried out using an endoscope. During termination, it is necessary to follow the corresponding termination specifications or requirements strictly, and to terminate and inspect according to the respective node numbers. Note that the thickness of the insulation layer between the cable conductors used should match the spacing between the contacts, and the cable cores should be compatible with the connection terminals of the contacts; cross-connections and parallel connections should be made between the contacts as appropriate. Furthermore, if the cold-press terminals are in a separated state, appropriate dust-proof measures need to be taken. If they are not separated for an extended period after being connected, a fuse can be installed between the plug and the socket. When cleaning cold-press terminal blocks, a silk cloth dipped in anhydrous ethanol can be used, and it should be used after it has dried. The use of equivalent chemical solvents that may have a harmful effect on the connector is not allowed. It should be noted that whether connecting or disconnecting, it is recommended to align the axis lines of the plug and socket as much as possible, and to keep the cable straight to avoid any tangential forces acting on the plug, thereby preventing the cable from sagging and causing damage to the connector. Power supply must not be applied to cold-pressed terminals until they are properly connected and fully secured. In applications such as fixation and clamping of wiring harnesses, anti-loosening devices should be used when threaded connections are employed. PCB terminals also require acceptance and testing, and during this process, operations must be carried out in accordance with the relevant instructions. When accepting and inspecting used electrical connectors, the requirements are generally lowered based on the relevant product standards and user manuals; the pressing tools used for processing the terminals must be in good condition and of satisfactory performance ； The probe should meet standard requirements; otherwise, it may cause damage to the socket.
