1731120120, or D-subminiature connectors, are a connector type frequently found in electronic systems. They are made from metal shells with contacts protruding through their backs and are most commonly used for connecting computers, computer peripherals, and audio equipment.

Application field

The D-shaped connector’s versatile design allows them to be used in a wide range of applications. The most common uses include providing connectivity for devices such as keyboards, mice, serial printers, and video monitors. They are often used in electronics to link larger components such as motherboards to system buses and cables.

The D-subminiature connections are useful in CCTV and security camera systems that require multiple connections. The connector type is also commonly used in medical imaging equipment, musical instruments, and two-way radios.

Working principle

The D-shaped connector works by connecting two mated contacts within a metal housing. It typically has 9 to 50 pins for electrical connections. The connector is designed to carry digital or analog signals and to provide power to devices such as printers and other peripherals. It can also be used as an audio connection point for connecting external speakers, headphones, and other devices.

Inside the metal housing are two arrays of terminals arranged perpendicularly. The terminals are formed by punching out portions of either the metal housing or the contact strips, allowing them to make contact with each other when mated. The connector is usually secured by screws, which must be tightened for a reliable connection.

Conclusion

D-subminiature connectors are a reliable and versatile connector type, making them a popular choice for a wide range of applications. Thanks to their durable design and easy installation, these connectors are widely used in electronic systems around the world.
