The needle structure and punching structure of D-SUB connectors

The D-SUB connector is a commonly used electrical connector in computers, named after its shell resembling the letter 'D'.
The pin processing process for D-SUB connectors includes two types: turning pin and punching pin. Car needle refers to a solid pin produced by a lathe. The solid structure makes the pin structure stable, not easily deformed, and has a longer service life. At the same time, it has more gold plating, strong conductivity, and low resistance. Punch needle refers to the hollow contact pin punched and formed on the precision punch, which is slightly lower than the lathe needle structure in structural stability and transmission performance. The D-SUB connector with better performance and higher cost is commonly used in industries, energy, and other fields with higher quality requirements. The D-SUB connector for car needles is mostly used for conventional commercial grade equipment.
