What Factors Will Affect The Quality And Life Of The Terminal Block?

As an important connecting element, terminal blocks are well used in many industries. In the production process, which factors will directly affect the quality and service life of terminal blocks? In terms of hardware materials, the quality of the materials directly affects the electrical performance and connection performance of the terminal, which plays an important role in the electrical connection. The design of the terminal is an important factor to determine the quality of the terminal. Because the conductivity of the material directly affects the temperature rise and contact resistance, and the elasticity is related to the chemical elements, elastic modulus, hardness and tensile strength of the material. The higher the conductivity of the material is, the smaller the contact resistance is, the lower the temperature rise is. The relationship between the plug-in force and the contact resistance is a quadratic curve. In the aspect of electroplating, the plating layer also directly affects the main factor of the terminal life. As far as gold plating and silver plating are concerned, the conductivity of silver is higher than that of gold, but its chemical stability is not as good as that of gold plating. However, the cost of gold plating is high. Only the products with acid environment or worse application environment are recommended to use electroplated gold. Moreover, local gold plating is applied to the contact part of the pressed sheet, which not only ensures the improvement of service performance, but also greatly reduces the product cost. Therefore, attention should be paid to these details in the production of terminal blocks, so as to ensure the quality and service life of terminal blocks and provide guarantee for enterprise production.
