D-Sub Connectors

The 192-009-113-171 D-Sub Connector is a type of electrical connector used generally in the computer industry. These connectors are designed with a number of metal contacts that are arranged in two rows; each row contains 9 of the contacts. It is attached to a cable or an adapter board by means of screws, solder, or crimping. It also permits a current to pass from one circuit element to another.

Application Field

D-Sub connectors, being flexible and versatile, are used in a wide variety of applications. They are primarily used in applications such as data connections, networking, video and audio, serial communications, motor control, and instrumentation. They often serve as a transitional link between a device and a host or a controller. Additionally, they are also used for digital I/O connections, hot swap/switch ports, and multiple bus applications.

Working Principle

The D-sub connectors have two parallel rows of metal contacts, one male and one female. The male row is connected to the device and the female row is connected to the host or controller. When the two rows of contacts are connected, a current is allowed to flow. This current can be used to transfer data, power, or both.

For data transfer, D-Sub connectors utilize an internal switching action that allows the male contacts to connect with their corresponding female counterparts. This provides a secure connection. For power transfer, the contacts provide the power to the device while still maintaining the electrical connection.

The contacts on a D-Sub connector are rated based on their current flow rating. This is the amount of current that a contact can safely support. The amount of current the contacts can support is dependent on the size of the connector as well as the type of material used in its construction.

Conclusion

D-Sub connectors, also known as D-Subminiature, are electrical connectors commonly used in the computer industry. They are designed with a number of metal contacts that are arranged in two rows. The connector is generally connected to a cable or adapter board, allowing an electrical current to pass from one circuit element to another. D-Sub connectors can be used in a wide variety of applications, such as data connections, networking, video and audio, serial communications, motor control, and instrumentation. They employ an internal switching action for data transfer, and a direct contact for power transfer.
