D-Sub connectors are a group of connectors that feature two rows of pins in a D-shaped form. The D-Sub series of connectors are widely used in a variety of applications, ranging from the personal computer to test and measurement equipment. The subgroup of D-sub series, known as backshells, hoods, are necessary components that help to protect the front end of the D-sub connector from any potential environmental, mechanical, or electrical damage.

The design of the D-sub series of connectors is such that it is capable of carrying a variety of signal types, ranging from simple digital signals to differential signaling and ethernet. The main difference between the various types of D-Sub connectors is the position of the pins, with the majority of D-Sub connectors featuring two rows consisting of 9 to 50 pins each in a D-shaped form. Additionally, various sizes and configurations of the D-Sub connector series are available, allowing the necessary modification of the connector for various applications.

The design of the D-sub connector is such that it requires additional components for a proper installation. The various components necessary for a complete installation of the D-Sub connector series include a backshell, a hood, and a strain relief. The backshell, also known as a connector shell or connector cover, is the main protective component of the connector, as it completely encloses the pins and the threads of the connector, and helps to protect the pins from potential damage from the environment or mechanical failure caused by incorrect installation. To increase the environmental protection, some backshells include an additional seal to help protect against dust and water from entering the connector.

The hood of the D-sub connector is responsible for providing the necessary strain relief of the wire or cable attached to the D-sub connector. The hood is designed to firmly grip the cable or wire and apply a mechanical force to the wire as it is inserted into the corresponding D-sub connector, essentially preventing any damage caused by remove or excess strain occurring on the cable.

By providing a combination of protection from environmental hazards, as well as a secure connection on both sides of the connector, the backshell, hood, and strain relief components of the D-Sub are essential in ensuring a reliable connection and transmission of signals across various applications.

The D-Sub series of connectors is well suited for many applications, such as the personal computer, test and measurement equipment, and the connection of audio and video cables. Its high density, combined with a robust design and reliable connection have made it the go-to solution for many applications. The addition of a backshell, a hood, and a strain relief, helps to make the D-Sub connector even more reliable, as the included components provide necessary protection and strain relief.
