D-Sub, D-shaped connectors are a type of electrical connector commonly used in computers, telecommunications, and other computing systems. The connectors come in nine different sizes, ranging from 9 to 44 contact positions. They are easy to install, low cost, and provide high reliability due to their design and material construction.The contacts of D-Sub connectors are typically available in different levels of durability, depending on the application. A preferred option in certain electronic applications is supplied with gold-plated contacts which can resist higher temperatures, corrosion, and wear. Gold platings are used in connection and contact systems that require extraordinary long lives such as in consumer applications, and military and aerospace programs.The contacts of D-Sub connectors are designed to be of two basic types. The first type, commonly known as pin contacts, are comprised of a flat contact face which is either formed in the shape of a pin or as a protruding metal finger. The contacts are held in place with a series of spring-loaded pins. The second type of contact is more commonly referred to as socket contacts and is composed of small individual flat strips which can be made in either square or circular curvatures.The contact material used in D-Sub connectors can be either solid metal or a conductive plastic such as copper or nickel in combination with a plastic material. The type of the material will be determined by the application being served, and the requirements needed. The contacts are held in place on the connector body by either soldering or soldering-on procedures. For the assembly of pin-type contacts, the pin contact is inserted into the socket of the connector body and then soldered to the board. The contact design of the D-Sub connectors is also important in terms of the soldering techniques needed. There are two main types of soldering being used, the hot bar process and the wire wrap technique.The hot bar process uses a heated bar that is laid across the top of the connector body prior to soldering. This process melts the solder, fuses the pin contact to the board, and forms a permanent connection. The wire wrap technique is used mainly with cable harnesses where the wires are distributed across the individual contact locations and then twisted around the contact. This creates a strong and reliable bond between the contact and the board.Overall, the D-Sub connector concept provides a relatively low-cost and reliable way of connecting two or more electrical circuits. Their design is simple, yet their ability to handle a wide range of conditions makes them a preferred choice for many applications. In conclusion, the D-Sub connector has become a commonly used and reliable connector choice for many commercial and industrial applications. It’s versatility and reliability make it a preferred option for many electronic devices. Its range of contact styles and materials allow it to be used in a wide variety of applications and with a variety of power and signals. Its low cost and wide range of size options make it the popular choice for many applications.
