D-Sub, D-Shaped Connectors - Housings

D-Sub, D-shaped connectors are commonly used with multi-pin electronic connectors and are characterized by their trapezoidal shape and pin configurations. The “D” stands for “dual-pipe”, which describes their shape. The connectors may contain anywhere from two to hundreds of pins, depending on the application.

D-Sub connectors come in a variety of forms, such as solder and crimp, and in various sizes ranging from miniature to large. They are also available with either a male or female gender, and can be used in a variety of applications, including data, audio, video, and power management.

The housings of D-Sub connectors are usually made of aluminum, steel, plastic, or die-cast zinc. This is important in order to provide stability, rigidity, and strength during the assembly process. Additionally, the housing also provides shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). The housings of these connectors feature protective caps that can be opened and closed in order to prevent dust and moisture from entering the connector.

While the housings of D-Sub connectors are typically black in color, they can be purchased in a variety of different finishes, such as silver, nickel, gold, and gray. In addition to the color of the housing, the connectors can also be purchased in a range of different sizes, from standard to jumbo.

The working principle of D-Sub connectors is quite simple. The pins and sockets are arranged in a specific pattern and are often referred to as a “banks” of pins. When the connector is plugged in, the pins on one side pass electrical signals through the connector to the corresponding sockets on the other side.

D-Sub connectors have a variety of applications, from computer and automotive applications to industrial and medical uses. They can be used to connect digital and analog components, such as sensors and actuators, as well as connecting computer peripherals, such as keyboards and printers. Additionally, D-Sub connectors can be used for signaling, control, and data communications in many applications, including test and measurement equipment, broadcast audio, and communications systems.

Overall, D-Sub connectors are extremely versatile and are an integral part of many electronics. Their robust construction, versatility of shapes, and wide availability of sizes make them a common choice for multi-pin electronic connectors.
