What Is a D- Sub Miniature Connector?
A D-sub miniature connector is a common type of electrical connector. They get their name for their characteristic D-shaped metal shield. D-subs were among the smallest connectors used on computer systems when they were introduced.
D-sub miniature connectors refer to a wide range of connecting devices that share the common characteristic of a D-shaped metal plate surrounding the output pins. These connectors are more narrow on the bottom than they are on the top. This feature ensures that the orientation of the connector is always correct when joining with the receptacle. Furthermore, it prevents interference with the signals running through the contact points within it.
How A D-Sub Miniature Works
D-sub connectors contain two or more parallel rows of contacts surrounded by its characteristic D-shaped metal shell. This shell primarily provides mechanical support for the connector. It also ensures the correct orientation. However, it may screen against electromagnetic interference (EMI).
There are several methods to connect the system circuitry to the contacts in D-sub connectors. This includes crimp, solder cup, PCB solder, PCB press-fit and wire wrap connections. In many instances, locking systems are implemented to ensure the connectors remain in a mated state despite shock and vibration conditions.
You many also hear D-subs referred to as “rectangular rack and panel” connectors. On top of that, they often carry vernacular references such as DB9, DB15, DB25, DB37 and DB50 where the numbers refer to the connector’s pin count. Our staff of experts understand the differences between models and will work with you to get you what you need. So do not hesitate to reach out to us.
How To Use It
D-sub connectors work with a wide variety of electronics. You often find them on communications ports, creating connections between different products, like computers, printers, and power supply units. Some can be used for token ring networks, as well as other computer networks and the controller area network (CAN).
The most common application for d-sub miniature connectors are on computer motherboards. Typically, they serve the VGA video output, serial port, and a variety of other specialized uses. The fact they are so common is due to how simple they are to use. They are nearly fool-proof! Common d-connector hardware usually includes two screw clamps. These clamps ensure a tight and durable connection is made.
They are very versatile and adaptable. So they have a proven track record with both consumer computing and industrial electronics. Another few popular uses for a d-sub miniature connector is for computer video output, game controller ports, multi-channel analog, and AES digital audio in recording studios.
As time goes on, the use of the connector has varied along with the changing technology. In the past, you could find them used to connect external floppy disks, but of course that is outmoded. And their use in consumer products has all but disappeared. This is mainly due to their size and cost. However, a d-sub miniature connector is still popular in non-consumer applications. This is due to the fact that its form factor, size, density and cost combination offers value.
