D-Sub Connectors

D-sub is short for D-sub connector, which is a type of electrical connector which is used to connect two electrical devices in a controlled manner. They are widely used in a variety of applications including automotive, industrial, and consumer.The 3–1740194-2 is a high-speed signal and power d-subminiature connector, which is designed for the high-speed data applications providing significant electrical and physical improvements over the traditional d-sub connectors. The connectors support standard slot sizes as narrow as 2.54mm (0.1 inch) for high performance transmission.

Application Field

The 3-1740194-2 connector is suitable for many applications such as: I/O connections, power and signal connectors, computer peripherals, networking, instrumentation, automotive, communications, and consumer electronics.

Working Principle

The 3-1740194-2 is a high performance d-sub connector that uses a two-piece design. The male form of the connector consists of a header and a shell. The header is the part of the connector that makes contact with the mating part, while the shell encloses the header and helps provide additional strain relief.The contact pins in the header are designed to provide maximum contact area and reduce contact resistance. The contacts are gold plated and the shell can be made from stainless steel or anodized aluminum. The male contact pins are spring-loaded and self-aligning to ensure a secure and reliable connection.The female part of the connector consists of a socket and a shell, where the socket is the part that makes contact with the mating part and the shell provides strain relief. The socket has contact pins that are made from gold plated brass and the shell can be made from either stainless steel or anodized aluminum. The pins are held in place by a spring that allows them to move in and out to ensure a secure connection.Overall, the 3-1740194-2 is a high performance connector that provides reliable connections and is suitable for many applications. It is designed for high speed data transmission and provides improved electrical and physical properties over traditional d-sub connectors.
