Introduction to D-Sub Connectors

D-Sub connectors are types of connectors used to transmit data between two systems, computers, and other electronic devices. They come in a variety of shapes and sizes with various features such as pins, holes, and slots that allow for transferring data and power between the two systems. These connectors are also called d-subminiature connectors, d-subs, or abbreviated as D-subs.

Types of D-Sub Connectors

D-Sub connectors come in a variety of shapes and sizes, but the most common type is the D-subminiature connector, which is used for smaller device applications. This type of connector is typically available with a choice of open, closed, or mixed layouts. Open layout d-subs typically feature a plastic shell that contains two flat metal contacts, which are the alignment pins that help keep the plug (male) and socket (female) together. Closed layout d-subs feature a smaller, rounded shell with two or more alignment pins and the contacts are hidden inside the shell. Mixed layout d-subs feature a combination of open and closed layouts, and typically have a slimmer, more lightweight profile that helps reduce the size of the overall package while providing enhanced durability and improved contact protection.

Types of Contacts

The types of contacts used in D-Sub connectors are typically made of stainless steel, bronze, phosphor bronze, and brass. The contacts used in D-Sub connectors are designed specifically for the application, with the number of contacts varying from two to over 2,500.

2744377 Application Field and Working Principle

The 2744377 is a type of D-Sub connector with a circular connector and an open layout. This connector is typically used in medium to high-speed applications such as USB 2.0 ports, audio and video devices with HDMI connections. The connector can also be used in power applications, and its working principle is based on an electric current going through the contacts and creating an electro-magnetic force, which binds the plug and socket together. The connection is made by the plug’s pins going into pre-defined slots in the socket, and the entire connection is sealed up with a nut which is tightened when the plug is fully inserted.

Conclusion

D-Sub connectors are an efficient and reliable way to connect two systems. These connectors are available in a range of shapes and sizes, with different contact configurations and features such as open and closed or mixed layouts. The 2744377 D-Sub connector is a specific type of D-Sub connector which is typically used in medium to high-speed applications such as USB 2.0 ports. Its working principle relies on electro-magnetic force that binds the plug and socket together when the pins are inserted into the pre-defined slots on the socket, forming a secure connection.
