The D-type connector, also known as the D-sub miniature, is a commonly used electrical connector in computers. With the development of science and technology, D-type connectors have gradually developed a number of specifications and models, which mainly include five types:
1. Stamping and forming D-type connector
The pins and sockets of stamped D connectors are made from flat sheet metal (usually tinned brass) and form cylindrical contacts and are the most commonly used contact type in commercial connectors.
2. Mechanical D-type connector
The contacts of mechanical D-type connectors are usually made of solid metal (such as gold-plated copper) and are high-quality contacts designed for demanding applications. Such connectors generally have a mating life of more than 500 cycles.
3. Crimp D-type connector
D-type connectors with crimp contacts have excellent environmental performance and are often used in high-end terminals such as military equipment.
4. IDC D-type connector
IDC D-type connectors have the advantage of quick assembly, which makes them the most popular interconnection choice for simple data transfer. But the disadvantage is that the pinout is limited, and the choice of cables is limited to ribbon cables.
5. Shielded D-type connector
Shielded D-type connectors provide greater EMI/RFI protection. Prevents communication interference and is typically used in environments where signal clarity is critical. Protect the signal transmission stability and reliability of the equipment.
