D-Sub, D-Shaped Connectors - Contacts

D-sub, D-shaped connectors are a type of rectangular connection device commonly used in a wide range of electronic devices. They are regularly found in computing and telecommunications applications and are popular in applications such as floppy drives, serial and parallel port devices, computer networks, and internal cable connections.D-sub connectors are typically made of metal and can contain an array of pins, sockets or both, depending on the desired application. Generally, the male version – with the pins – is referred to as the “plug”. Its female counterpart – with the sockets – is referred to as the “receptacle”. These connectors are most often available in the following connection configurations: DB9, DB15, DB25, and DB37.The basic construction of the contact elements for D-sub connectors consists of a top, bottom, target, and terminal. On the top of the connector, the contact is fitted into the insulation, while the bottom is secured by a solder cup. The target contacts, as the name implies, contain a target and the contact is crimped towards the target. The terminal is crimped onto the end of the contact wire and soldered into the bottom of the connector.Because of their construction, D-sub connectors can be used for a variety of different applications. Very low powered circuits, such as those found in USB cables, are sometimes driven through D-sub connectors, while higher power connectors are also used in switches and relays. Aside from these power applications, D-sub connectors are often used in computer and networking applications, particularly for serial data transfer. The DB25 connector is a particularly popular choice for these applications.The primary advantages of using D-sub connectors are reliability, robustness and cost. D-sub connectors provide a robust connection and are able to withstand harsh environments and forces, making them a reliable choice for many applications. They also offer a good balance of cost efficiency and high production quality, making them the ideal choice for many budget-sensitive projects.Aside from the standard configurations, D-sub connectors can also be customized to almost any specifications. One example of such a modification would be to add additional pins or sockets for more demanding applications. Customized features like these can help manufacturers create custom tailored connectors for a wide variety of applications, which further enhances the cost-efficiency of these connectors.In conclusion, D-sub connectors are an important part of electronic technology, and have been used for many decades in many different industries. They offer a reliable connection, good build quality, and are cost efficient. Furthermore, they can also be customized to meet the specific needs of a project, making them the ideal choice for many applications.
