What factors will affect the quality and lifespan of wiring terminals?
As an important connecting component, terminal blocks have been well used in many industries. So, what factors directly affect the quality and service life of terminal blocks in the production process?
In terms of hardware materials, it is important to use components that have conductive current and must have elasticity, such as compression plates for wiring terminals. The quality of the materials directly affects the electrical and connection performance of the terminals, and plays a crucial role in electrical connections. The design of wiring terminals is an important factor in determining the quality of the wiring terminals. Because the conductivity of a material directly affects temperature rise and contact resistance, the quality of elasticity is related to the chemical elements, elastic modulus, hardness, and tensile strength of the material. The higher the conductivity of the material, the smaller the contact resistance, and the lower the temperature rise. The relationship between insertion and extraction force and contact resistance is quadratic. In terms of electroplating, the electroplating layer and film layer are also the main factors that directly affect the lifespan of wiring terminals. In terms of gold and silver plating, silver has a higher conductivity than gold, but its chemical stability is not as good as gold, resulting in a much higher film resistance than gold plating. However, the cost of gold plating is high, and it is only recommended to use products in acidic or more harsh application environments. Additionally, local gold plating is used on the contact area of the pressing plate, which not only ensures improved performance but also greatly reduces product costs. Therefore, when producing wiring terminals, attention should be paid to these details to ensure the quality and lifespan of the wiring terminals, and provide assurance for enterprise production.
