D-Sub Connectors

D-sub connectors are a family of electrical connectors that have been designed to link communication equipment and computers. They consist of female and male connectors, each of which have several contact pins or sockets. Depending on the application, the types of connectors and pins used in D-sub connectors can vary. For example, a 2221760-3 connector is used for low-level signal connections.

2221760-3 Application Field and Working Principle

The 2221760-3 is a type of D-Sub connector that is used in applications that require low-level signal connections, including audio and video connections. The 2221760-3 includes two terminal sockets and nine contact pins. The terminal sockets consist of an inner layer of nylon and an outer layer of metal, which provides protection against friction and wear. The contact pins are Teflon-insulated copper wires with gold-plated tips.

The 2221760-3 is designed to work with low-level signal connections and operates using the principle of electrical continuity. The electrical continuity of the connection is established when the contact pins are inserted into the terminal sockets. When connected, the Teflon insulation prevents the electrical current passing through the terminal sockets from becoming wet or contaminated by oil or other contaminants which could cause corrosion or oxidation.

The 2221760-3 is typically used in applications such as video surveillance systems, interactive displays, and video conferencing systems. It is also used in industrial and medical equipment, communication systems, and for connecting peripheral devices such as keyboards and mice.

Advantages of the 2221760-3

The 2221760-3 is designed to provide low-level signal connections with excellent performance and durability. The benefits of using the 2221760-3 include:

• Corrosion-resistant terminal sockets and contact pins
• High-quality materials for improved performance and durability
• High-quality insulation for improved safety and reliability
• Cost-effective solution for low-level signal connections
• Wide range of applications
