D-Sub Connectors

D-sub connectors, also known as D-Sub, D-subminiature, or VHDCI connectors, are a type of electrical connector used in a wide range of applications. They are especially useful for connecting two or more electronic devices when precise place selection or space-saving is important. The most commonly used type of D-sub connector is the 747321-2 style, which features two male contacts, two female contacts, and two slots, with contact pins that fit into the slots for secure connection.

747321-2 Application Field

The 747321-2 style D-sub connector is used in a variety of different fields. They are mainly used in industrial applications that require precision data connections or short amounts of power. They are also used in many different types of audio-visual equipment, such as sound systems, video-recording equipment, music production, and more. Another common application of the 747321-2 connectors is in telecommunications. Many telecom systems such as cell phones, digital television, and radio systems use these connectors to ensure reliable data connections. In addition, they are also heavily used in IT and computing, where they are often used to link computers with peripheral devices, such as keyboards, mice, and printers.

747321-2 Working Principle

The 747321-2 style D-sub connector has two male contacts, two female contacts, and two slots. The contacts always fit precisely into the respective slots, making a secure connection. When pressure is applied to the sides of the contacts, they are forced into the slots, allowing them to make a reliable electrical connection. The male contacts are usually made of nickel or gold-plated brass, while the female contacts are usually made of tin or gold-plated brass. The contacts are designed to ensure maximum conductivity and a low-resistance connection.In addition to providing a secure electrical connection, the 747321-2 style D-sub connectors are also designed to reduce noise. The contacts are surrounded by an inner sleeve, which works to insulate the connectors and reduce radio frequency interference (RFI) and electrical noise. The connectors also include a mechanism for grounding the pins, which further reduces noise by providing a path for stray electrical current to be dissipated. Overall, the 747321-2 style D-sub connector is a reliable and versatile connector that can be used in a variety of different applications. The secure electrical connection and noise-reduction capabilities make it ideal for use in industrial, audio-visual, and telecommunications applications.
