Three important factors affecting the quality of terminal components

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.

The main surface of the wiring terminal is mainly made of plastic molds and metal continuous molds. The quality of mold design and manufacturing has a significant impact on terminal components. Product structure: such as anti falling screws, curved front and back of spliced products, long digit deformation, and shrinkage deformation caused by uneven wall thickness. There are currently several ways to prevent screws from falling off: three ribs from falling off, hoop mouth from falling off, neck mouth from falling off, and stamping from falling off. Due to the influence of technological processes, there are not many ways to prevent neck mouth from falling off, and most of them use neck mouth from falling off. The main reason for the deformation problem of long digits in the combination of splicing products is also due to the unreasonable structure, which leads to the imbalance of force on the two splicing eagles in front, back, up, down, left, and right, When designing the structure, it is necessary to consider the force and deformation direction of the spliced falcon.

The CTI parameters must meet the requirements during design, which directly affects whether the final product can pass tests such as impulse voltage resistance and aging resistance. According to UL regulations, no more than 25% of the recycled material can be mixed with 75% of the new material after thorough mixing, especially for products that can withstand high currents and voltages, the use of recycled materials should be lower or not added.

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.
