D-Sub Connectors

0848149012 Application Field and Working Principle

D-Sub connectors are electrical connector devices commonly used in the assembly and connection of electronic equipment. They have two main components: contact and housing. The contact is a metal pin or socket, which is inserted into the housing, which in most cases is a metal shell containing multiple contacts. The contact is usually made of brass and silver plated, while the shell is usually made of aluminium or steel. The terms ‘D-sub’ and ‘D-sub connector’ are derived from the distinctive ‘D’ shape of the contact male and female components. This shape not only provides an easily identifiable connection but also ensures that the components form an efficient but effective electrical connection that is physically tight and therefore secure.

In terms of application fields, D-Sub connectors can be used in any electronic system that requires multiple electrical connection points. These typically include computers, industrial, test, and measurement, telecommunications, military, aerospace, and medical applications. By virtue of their physical contact shape, D-Sub connectors are often the most suited to use in applications where minimal signal distortion is required. This is especially true in applications that require data transfer rates of more than 1 Gbps.

D-Sub connectors generally operate through a combination of force and contact surfaces that create a single reliable connection between two electrical circuitry. The contact surfaces are usually constructed as a hollow-shaped cavity or groove that contains metal pins or sockets. The pins or sockets are held in place by a compression spring, which applies a force to the contact surfaces when the connector is inserted into a mating socket. This friction between the surfaces ensures the contact remains secure during operation, which helps to reduce electrical signal distortion.

The working principle of a D-Sub connector is quite simple. When two devices are connected with a D-Sub connector, the contact surface on the socket creates the electrical connection between them. The contact surface contains metal pins or sockets which are held secure in place by the compression spring. When the connector is connected, the pressure is passed through the spring and applies a force to the surfaces. This force creates a secure electrical connection and ensures minimal signal distortion.

In summary, D-Sub connectors are electrical connector devices used in a range of electronic systems for effective electrical connection. This type of connector is usually constructed as a ‘D-shaped’ cavity that contains metal pins or sockets, which are held in place by a compression spring. The force from the spring creates a secure electrical connection and reduces electrical signal distortion, which makes it suitable for many different application fields. The working principle of a D-Sub connector is simple and effective, making it an invaluable tool for many different types of electronic systems.
