D-Sub or D-shaped connectors are connectors with two flat sides that include a combination of male and female ports. Typical applications include computer devices such as laptops, desktop computers, game consoles, and printers. They are also commonly used on existing and emerging industrial automation machines. Backshells, hoods, and other accessories play an important role in the overall design of D-Sub connectors.

A backshell is typically used to terminate or secure cable inside a connector. It provides an additional layer of strain relief and protection from the elements as well as additional strain relief. The specific type of backshell and number of pieces commonly depends on the size and style of the cable to be used in the application. In general, there are two types of back shells that are used for connectors: straight and ninety-degree with “L” and “U” shapes.

The hood is the protective piece that covers the backshell and is connected to the connector body. It is designed to prevent the entry of dirt, moisture, dust, and other elements that potentially could affect the performance of the electrical system. It also helps to create a firm mechanical connection to the cable while providing a physical barrier for dust, fluids, and other contaminants.

D-Sub connectors are commonly used with different types of cables depending on the requirements of the specific application. The type of cable used is often determined by the application’s shielding requirements, the size and weight of the cable, as well as the frequency and type of usage. Most commonly, coaxial and flat ribbon cables are used. To ensure optimal performance, the cable type and size must be chosen carefully.

The basic working principle of a D-Sub connector is quite simple. It is composed of two pieces – the male and female connectors. The male connector is inserted into the female connector and, when fully connected, establishes an electrical connection between the two. The connectors themselves consist of a set of pins which are lined up in the same type of arrangement. When these pins are connected, they allow electric current to pass through the connection.

The design of the D-Sub connector varies based on its usage in a given application. It is typically composed of two metal plates which are connected in a flat pattern. These plates can be connected with an additional fastening device such as a clip or screw. This helps to ensure that the connection remains secure during operations.

D-Sub connectors are designed to provide secure, reliable connections in applications with varying degrees of environmental exposure. In many cases, it is possible to order custom connectors to meet specific demands. Furthermore, hoods, back shells, and other accessories make it possible to adapt the connector for a wide range of applications.
