Abstract: the good or bad of the terminal not only depends on the good conductivity / signal transmission and insulation material, but also depends on the appearance design. The appearance edge of the terminal shall be smooth and flat without excess material.
If the outer edge / corner of the terminal is irregular, this phenomenon is usually called "burr or non edge". Below, Ningbo Hongyi Xiaobian will introduce the root cause of burr on the wiring terminal?
Root cause of burr in wiring terminal
I. mold and manufacturing process
1. In the process of mold manufacturing, the mold designer needs to design drawings according to the needs of users, and the products manufactured by using high-quality raw materials can be regarded as qualified.
2. Mold processing process. In the process of mold processing, there are generally electric pulse, electronic polishing and so on, which improves the accuracy of the mold.
2、 Production stage of terminal blocks
In the mass production of terminals, some hot operators are eager to fill the products, so they adjust the pressure of the injection molding machine to a high level at the beginning, but this is harmful to the mold. Long-term high pressure will usually deform the mold and affect the quality of product
