D-sub connectors are a type of electrical connector containing rows of pins and sockets encased in a steel or plastic shell. They are widely used in telecommunications, computing and test/measurement equipment. Also known as D-shaped connectors, they feature a characteristic D shape, often with 15, 25, 37, 44, and 50 pin configurations. More recently, they have even been released with up to 100 pins and come in high-density and mini variants.

D-sub connectors have distinct advantages over other types of electrical connectors; among these are their low cost, ease of use, and wide range of configuration options. Instead of a round conductor, D-sub connectors features pins and sockets in a rectangular pattern, producing an even greater number of contact points between two mating connectors. This allows for greater data transmission speeds and ensures that a stable, reliable connection can be made between two connected devices.

A typically D-sub connector features a shell with various ports to house the contacts, which are made of copper and gold plated for conductivity. The contacts are secured to the shell with pressure-sensitive clips. These clips hold the contacts in place, preventing them from coming loose over time and losing electrical connection.

The shell of a D-sub connector consists of two parts; the backshell and the hood. The backshell is a metal cylinder with a circular opening at one end and the other end screwed closed, with thumbscrews or snap clips providing access to the contacts within. The backshell surrounds the contacts on the mating side of the connector.

The hood is the outer covering of the connector that provides protection from physical damage. It consists of a plastic base joined by two metal caps, which are usually black in color. The hood is designed to protect the inner shell and contacts from dust, debris, and other contaminants. It also provides stability to the connection by preventing the inner shell from flexing or cracking.

The multi-purpose nature of the D-sub, combined with its cost-effectiveness, has made it the go-to connector choice for many industries, including from special applications such as industrial, automotive, data center and telecoms. The various sizes also allow it to be used to connect CompactPCI, SATA, USB and fibre optic systems with different equipment and ports. Thanks to its versatility and affordability, the D-sub connector is likely to remain the king of electrical connectors for many years to come.
