1. It is necessary to fully understand the cold pressed terminals to be operated, and be familiar with their operation methods, so as to ensure correct operation; for cold pressed terminals without anti misoperation, color codes or marks shall be used for identification, or whether the appropriate models correspond before connection, and the correct positioning shall be ensured during mutual connection; special attention shall be paid to prevent the wrong insertion of the pin socket, otherwise, the cold pressed terminal will be damaged and conducted External electrical contact: ensure that the cold pressed terminals are connected in place. In special occasions that are not easy to check, detailed provisions should be made in the corresponding operation procedures, and inspection can be carried out through the endoscope.
2. When the cold compression terminal is terminated, it shall be terminated and inspected in strict accordance with the corresponding termination specifications or requirements, and shall be terminated according to the corresponding node serial number. The thickness of the larger insulation layer between the selected cable conductors shall match with the contact spacing, and the cable core shall match with the contact terminal. When the contact is spanned or merged, it shall be treated.
3. When welding, the electric iron with corresponding power should be selected according to the diameter of bare wire. The welding time of each contact is generally less than 5S. Attention should be paid not to let the flux penetrate into the insulator, so as not to cause the product insulation resistance to drop.
4. If the cold compression terminal is in the separation state, it is necessary to install protective caps or take other dust-proof measures; if the cold compression terminals are not separated for a long time after connection, the safety can be provided between the plug and the socket.
5. When cleaning the cold pressing terminal, the silk cloth dipped in absolute ethanol can be used, and it can be used after drying. It is not allowed to use chemical solvents such as acetone which may have harmful effects on connectors.
6. When cold pressed terminals are connected or separated, the axis lines of plug and socket shall be overlapped as much as possible, and the cable shall be righted to avoid the effect of tangential force on the plug and prevent the damage of connector caused by cable sag.
7. It is forbidden to electrify the cold pressed terminal before it is connected correctly or locked completely.
8. When the thread connection is used, the locking device (locking screw, locking ring, fuse, etc.) shall be provided when the cold pressing terminal is fixed and the wiring harness is clamped.
9. Acceptance and inspection of cold pressed terminals shall be carried out according to the requirements of relevant product standards and operation instructions. Acceptance and inspection of used electrical connectors shall be carried out on the basis of relevant product standards and operation instructions with reduced requirements. The cold pressed terminals of tooling used shall be intact and have qualified performance. The probe shall meet the requirements of the standard, otherwise the jack may be damaged.
