Summary: The quality of a terminal block doesn't solely depend on its excellent conductivity/signal transmission and insulating materials; it also hinges on its appearance design. The edges of the terminal block should be smooth and even, without any excess material.
If the outer edge or folded corners of terminals exhibit irregularities, this phenomenon is commonly referred to as "burrs or non-edges." Below, the Ningbo Hongyi editor will introduce the fundamental reasons for the occurrence of burrs on terminal connectors?
The Fundamental Cause of Burr on Terminal Connectors
I. Mold and Production Manufacturing Process
During the mold production process, mold designers must create drawings based on customer requirements and use high-quality raw materials to ensure the products are qualified.
2. The molding process. During the molding process, techniques such as electrical pulses and electronic polishing are commonly used, which enhance the accuracy of the mold.
Section Two: Terminal Block Production Phase
In mass production of terminals, some operators rush to fill the product to capacity, thus initially setting the injection molding machine's pressure too high. However, this is detrimental to the mold, as prolonged high pressure often leads to mold deformation, affecting product quality.
