How does cold pressed terminal wire ensure the firmness of electrical connection to avoid the problem of loose connection?
Publish Time: 2024-12-25
Cold pressed terminal wire is a common electrical connection method. The wire is connected to the terminal by inserting the wire into the terminal and pressing it with a cold pressing tool.1. Correct terminal selectionMatching wire size: Select a terminal that matches the wire size to ensure that the terminal hole diameter is appropriate and can tightly wrap the wire.Material compatibility: Select terminal materials that are compatible with the wire material, such as copper terminals for copper wire and aluminum terminals for aluminum wire to reduce the risk of electrochemical corrosion.2. Wire preparationRemove insulation: Accurately remove the wire insulation layer and retain the appropriate conductor length to avoid being too long or too short.Clean the wire: Before connecting, ensure that the surface of the wire is clean and free of oxide layer, dirt or other impurities.3. Correct insertion methodFull insertion: Insert the wire completely into the terminal hole to ensure that the wire is in full contact with the terminal.No kinks: Avoid kinking or bending the wire during insertion and keep it straight.4. Correct use of cold pressing toolsAppropriate tools: Use cold pressing tools that match the terminal size to ensure that the pressing force is moderate.Full pressing: Fully press according to the tool instructions to ensure a strong mechanical connection between the terminal and the wire.5. Check the quality of the connectionVisual inspection: Check whether the wire is fully inserted into the terminal and whether the terminal surface is damaged or uneven.Tensile test: Perform a tensile test on the connection to ensure that the connection is firm and will not loosen easily.6. Anti-oxidation treatmentApply protective agent: Apply anti-oxidant or conductive glue to the connection to prevent oxidation and improve conductivity.Sealing protection: For outdoor or humid environments, the connection can be sealed to prevent moisture intrusion.7. Regular maintenanceCheck the tightness of the connection:Regularly check whether the connection is loose and re-press or replace the terminal if necessary.Cleaning and maintenance: Clean the connection regularly to remove dust and corrosion to maintain good electrical contact.Through the above measures, the electrical connection firmness of the cold pressed terminal wire can be effectively ensured, the risk of loose connection can be reduced, and the stable and safe operation of the electrical system can be guaranteed.
