D-Sub, D-Shaped Connectors - Contacts

D-shaped connectors, better known as D-subs, are electrical connectors commonly used in computers, telecommunications equipment, and other electronic systems. They are also used for connecting cables together or to a panel. The term D-sub refers to the shape of the connector, which is a trapezoidal shape that looks like a capital letter D. The shape of the D-sub allows for easier stacking and provides more secure connections. The contacts are housed in a variety of enclosures, including snap-fit connectors, panel mount connectors, and screw-lock connectors, which can be used both internally and externally.

D-sub connectors are available in a variety of sizes and configurations. Common connector sizes include DB9 (9 pins), DB15 (15 pins), DB25 (25 pins), and DB37 (37 pins). The number of pins indicates the total number of contacts in the connector, while the size indicates the size of the connector body. D-sub connectors can be configured for either male or female connections depending on the application. A male connector usually has pins, while a female connector usually has sockets.

One of the primary advantages of using D-sub connectors is their ability to handle a wide range of signal types. Many types of signals, such as RS-232, RS-422, RS-485, and Ethernet can be transmitted through D-sub connectors, making them a popular choice for connecting computers and other devices. D-sub connectors are also popular for carrying high voltage signals, and can be used to connect devices to electrical power systems.

Another benefit of D-sub connectors is their durability. Most D-sub connectors are designed for multiple contact mating and are rated for up to 500 mating cycles. As a result, they are often used in industrial and military applications, which require a high level of reliability and durability. This makes D-sub connectors the ideal choice for applications where the connector needs to be connected and disconnected repeatedly.

The working principle behind D-sub connectors is relatively simple. The contacts in the connector are either crimped or soldered onto the cable, allowing the signal to travel from the source to the destination. The contacts on the connector match up with the pins in the female connector, allowing the two to make a connection. The connection is then held in place by the pressure of the metal spring contacts, which creates an electrical and mechanical connection.

In conclusion, D-sub connectors are a versatile choice for many different applications. They are durable, reliable, and can handle a wide range of signal types. Their trapezoidal shape makes them easy to use and provides enhanced stacking capabilities. They are also capable of handling high voltage signals and are usually rated for 500 mating cycles, making them ideal for industrial and military applications. The working principle behind D-sub connectors is quite simple, and the ease of connecting and disconnecting them makes them the go-to choice for many applications.
