D-Sub Connectors

D-Sub connectors, also known as D-subminiature connectors, are the most widely used type of connector for computer systems and other electronic equipment. These connectors are commonly used in a variety of situations, such as connecting video, audio, power, and other cables. By using these connectors, simple connections between computers and other devices can be made quickly and easily. This article will focus on the D-Sub21W1P connector, its application field and working principle.

Application Field

The D-Sub21W1P connector is most commonly found in computer system applications, as well as industrial and commercial applications. It is a popular choice for connecting video and other high-speed data signals because of its good electrical properties and shielding capabilities. The connector is also used for feeding power to various devices, such as LED lights or as a power connector for a computer system.

Another common application for these connectors is for PCB connections. The D-Sub21W1P connector is widely used in printed circuit boards, as it is reliable and low-cost. It is also typically used for creating connections between different components on the board, such as connecting an IC to other components on a PCB.

Working Principle

The working principle of the D-Sub21W1P connector is straightforward and simple. The connector consists of two pieces of metal that are connected together with an angled edge. The two pieces of metal have a hole in the center, where a small mating pin is inserted. The pin is moved in and out to make or break the connection between the two pieces of metal. This movement is called "latching" and allows for easy, reliable electrical connections.

The way that the connector works is by providing an electrical connection between two devices using the metal contacts. The contacts are usually made from copper or gold and are inserted into the hole in the center of the connector. When the pin is inserted, it creates a conductive path between the two contacts, which allows the electricity to flow between the two devices.

The D-Sub21W1P connector has a unique design that allows for a reliable and durable connection. Its shell has a rigid construction and is made from tough, wear resistant materials. The pins are also designed not to come loose when the connector is in use. This ensures that the connection stays secure even when the connector is subjected to vibration or other mechanical force.

The D-Sub21W1P connector is a reliable and durable type of connector that is widely used for a variety of applications. It is relatively inexpensive, and its simple design makes it easy to use and install. The connector is also highly resistant to vibration and other mechanical forces, making it an ideal choice for connecting two electronic devices together.
