Neutral Block: Quality Control Throughout The Entire Process From Raw Materials To Finished Products
As a key component in electrical connections, the quality of the neutral terminal directly affects the safety and stable operation of the circuit. Quality control throughout the entire process from raw materials to finished products is the foundation for ensuring reliable performance of neutral wire terminals.
In the stage of raw material selection, it is necessary to strictly screen copper materials with excellent conductivity and strong corrosion resistance as conductors. At the same time, fire-resistant and flame-retardant PC materials or ceramics should be selected as insulation materials to ensure the safety of terminals in high temperature environments. Suppliers are required to provide complete material testing reports to ensure that each batch of raw materials meets environmental and safety standards.
Entering the production process, the terminal crimping process is the core control point. Precision molds are required for crimping to ensure maximum contact area between terminals and wires and reduce contact resistance. During the crimping process, real-time monitoring of parameters such as crimping height and force is required to avoid contact looseness or breakage caused by poor crimping. In addition, the surface of the terminal needs to be smoothed to remove burrs and oxide layers to prevent electrical short circuits.
During the finished product inspection stage, multidimensional testing is required. Verify the reliability of the electrical connection between the terminal and the wire through conductivity testing; Use voltage withstand testing equipment to check the insulation performance of terminals at rated voltage; Evaluate the bonding strength between terminals and wires through tensile testing. At the same time, the appearance inspection should ensure that the terminals are not damaged or deformed, and the markings are clear.
In the packaging and storage process, moisture-proof and dust-proof packaging materials should be used to avoid damage to the terminals during transportation. The storage environment should be kept dry and ventilated to prevent the terminals from being damp and oxidized. Through full process quality control, it can be ensured that the neutral wire terminals meet high standard requirements from raw materials to finished products, providing a solid guarantee for the safe operation of the electrical system.
