D-SUB connectors are widely used in the computer field due to their shell shape resembling the English letter "D". This type of electrical connector is not only uniquely designed, but also has stable performance, making it an important component in many electronic devices.
The processing of pin pins is a crucial step in the manufacturing process of D-SUB connectors. According to different processing techniques, pin needles are mainly divided into two types: turning needles and punching needles.
Car needle is a solid pin carefully crafted through a lathe. This solid structure endows the needle with excellent stability and durability, making it less prone to deformation and extending its service life. In addition, the car needle has a higher gold plating amount, ensuring good conductivity and lower resistance. Therefore, the D-SUB connector for car pins performs outstandingly in terms of performance, but correspondingly, its cost is also higher. This type of connector is often used in industries, energy, and other fields that require extremely high quality.
In contrast, punch pins are hollow pins formed by precision punching. Although the punching needle is slightly inferior to the car needle in terms of structural stability and transmission performance, its manufacturing cost is lower, so it is mostly used in conventional commercial grade equipment.
