Introduction

D-Sub connectors (1-745968-6) are one of the most commonly used connectors in the electrical industry. They are used in a variety of applications, ranging from high-powered systems such as avionics, to everyday consumer electronics. D-Sub connectors are incredibly versatile and are used to connect a wide variety of signal and power functions.

Design and Construction

D-Sub connectors are square shaped, with two rows of pins arranged in a rectangular pattern. Typically, the connectors contain 15-40 pins, although some special applications require more. The pins are typically made of brass and held in place by a combination of solder or crimp connections. The connectors also feature primers and keyways, which ensure the pins line up properly when the connectors are mated. The shells are typically made of metal, plastic, or a combination of the two. This allows the connectors to hold up in high vibration applications, such as aircraft and automotive systems.

Application Fields

D-Sub connectors can be used in a variety of industries, including the automotive, aerospace, consumer electronics, military, industrial, and medical fields. Some of the most common uses include signal and power connections in avionics, instrumentation, and robotic systems.In the automotive industry, D-Sub connectors are used for data and power connections between the engine control unit and other modules, such as the climate control system. They are also used in military equipment, such as radios and communication systems, and in medical imaging machines, such as MRI and CT scanners.

Working Principle

D-Sub connectors work by creating a secure electrical connection between two components. When a connector is mated with its corresponding component, the pins and primers align and make contact with each other. This creates an electrical circuit that allows signals and power to flow between components.The connectors also have a latching mechanism, which keeps the connector mated even in environments with high vibration and physical stress. This ensures the connector stays securely fastened and prevents accidental disconnection.

Conclusion

D-Sub connectors (1-745968-6) are incredibly versatile and are used in a variety of applications, from high-powered systems such as avionics to everyday consumer electronics. They work by creating a secure electrical connection, and feature a latching mechanism that ensures the connector stays mated. D-Sub connectors are commonly used in the automotive, aerospace, consumer electronics, military, industrial, and medical fields.
