In today's electrical equipment operation process, the requirements for individual components are relatively strict. The quality of the material produced by the tabs at the terminal block will directly affect the electrical performance and connection performance of the terminal block. These two properties play a very important role in the terminal block connection process, and the design of the terminal block determines the quality produced by the terminal block. Therefore, no matter whether it is at the time of design or production, it is necessary to strictly control all the links, so that it can produce a terminal block suitable for the manufacturer. Below, Kenbo Xiaobian will tell you about the three parts that affect the terminal block components. Big important factor.

The main surface of the terminal block cloth is generally a plastic mold and a metal continuous mold as the main method. The quality of the mold design and manufacturing will directly affect the terminal components. Product structure: such as screw anti-drop, spliced products are curved before and after, long-term deformation, etc., shrinkage deformation caused by uneven wall thickness. There are several types of anti-dropping of the screw: the three ribs are prevented from falling off, the ferrule is prevented from falling off, the neck opening is prevented, and the punching is prevented.

When designing for the terminal block, the CTI parameters must all meet the requirements, otherwise it will affect whether the final product can pass the impact withstand voltage and aging test. According to UL regulations, no more than 25% of the recycled material can be mixed with 75% of the new material and mixed thoroughly. Especially for some products that withstand high current and high voltage, the use of recycled material should be lower or not. Add.

Regarding the terminal block in electroplating, the plating layer also directly affects the main factors of the life of the terminal. In the case of gold plating and silver plating, silver has a higher electrical conductivity than gold, but its chemical stability is not as good as gold, and the resulting layer resistance is much greater than gold plating.
