D-Sub, D-Shaped Connectors - Contacts

1727040157 Application Field and Working Principle

D-shaped connectors, also known as D-sub connectors or d-subminiature connectors, are interconnect components designed to provide secure connections of two different pieces of equipment. They are typically used in computer, industrial and military applications. The contacts of the D-shaped connectors are arranged in a square or round pattern and are typically made of durable metals such as aluminum and stainless steel.

The application fields of these D-sub connectors are quite broad because of their contact configuration and the nature of the connection they provide. For instance, they can be used to connect a power source to a computer or electronic device. This type of connection is also used for telecommunications and audio equipment, as well as for test equipment and instrumentation.

The working principle of these D-sub connectors involves two pieces of equipment which must be connected securely. The contacts in the D-sub connectors are called points of contact and each contact point will usually have a unique profile. This profile is typically comprised of features such as holes, ridges, notches, or flanges. When two pieces of equipment are to be connected, the contact points must line up perfectly, and when this happens the contact points will make a secure connection.

To ensure a secure connection, D-sub connectors are designed to make full contact. This means that all of the contact points must touch when they are in alignment as opposed to only making partial contact. This ensures that the connection is securely locked in place and can’t be easily disconnected. Additionally, these connectors will most often use a locking mechanism such as a screw or push-pull in order to further secure the connection and prevent accidental disconnection.

The contacts in a D-sub connector can also be designed to transfer different kinds of signals. Depending on the type of connector, the contacts can be used to transfer electrical signals, digital signals, fiber optic signals, or even a combination of all three. These connectors are also designed to operate at different current and voltage ratings, depending on the application.

In order to transfer signals, the contacts in the D-sub connectors are designed to be highly resistant to corrosion and oxidation. The materials used for the contacts are corrosion and oxidation-resistant metals such as aluminum and stainless steel. Additionally, these connectors are typically designed to be shock and vibration-resistant so that they can withstand the rigors of industrial and military use.

D-sub connectors are versatile interconnect components that can be used in a variety of applications. They are designed to make secure connections and to transfer different kinds of signals, making them an essential part of many different types of electronic equipment.
