D-Sub, D-Shaped Connectors - Contacts

D-sub connectors, also known as D-shaped connectors, are a type of electrical connectors used to connect electrical devices into a circuit. They are commonly found on computers, telecommunications equipment, industrial machinery, and more. They are typically made of metal and plastic, with contacts and/or screws for electrical connections. The connectors come in a variety of sizes, from small to very large, and are made to meet different requirements based on their intended use.

The design of D-sub connectors is relatively simple; they consist of straight pins or screws that connect two pieces of metal or plastic. The two pieces of metal or plastic need to be held together securely, typically by means of pins or screws. These connectors are typically used to connect electrical components such as switches, sensors, motors, and electrical wires. The contacts on the connector can be either plastic or metal depending on the type of material used for the connector.

There are two main types of D-sub connectors; male and female. Male connectors usually have two pins or screws and female connectors have one or two pins or screws. Male connectors are typically used to connect electrical components to the male side, while female connectors are used to connect components to the female side. In most cases, the pins or screws of the male and female connectors are designed to be able to "mate" with each other, meaning that when they are inserted into the female connector, they create a secure connection and electrical contact.

The electrical connection and contact made by D-sub connectors is critical for many applications. For instance, in computer networking, D-sub connectors are used to connect networks to each other. Furthermore, they are used to make connections between computers, printers, and other devices. In industrial automation, D-sub connectors are used to make connections between machines and controllers, or between sensors and controllers.

The working principle of D-sub connectors is relatively simple; two or more pieces of metal or plastic are held together securely by means of pins or screws, and when these pins or screws are connected to electrical components, they create a secure electrical connection and contact.

D-sub connectors are widely used in a variety of applications, from basic electrical connections to complex network and automation applications. The cost of these connectors varies based on the type, size, and complexity of the connector. Due to their versatility and cost-effectiveness, they are ideal for a variety of applications, from simple and straightforward connections, to more complex and customized applications.
