D-Sub Connectors

The MDM-31SH027P-A174 is a form of D-sub Connectors, which are used for electrical connections. In essence, they are connectors that are designed as pins and sockets that are used to join/connect two electrical devices. Furthermore, D-sub connectors are distinguished by their type of configuration and mounting. Typically, this type of connector is used when several signals have to be transmitted between circuit boards.

Application Field

In theory, D-Sub Connectors can be used in a wide variety of applications. In practice, the two main application fields are pc boards/electronic consoles and military/avionics interfaces. Additionally, they can also be used in medical, industrial, commercial, and instrumentation applications.

Regarding pc boards/electronic consoles, D-Sub Connectors are used mainly for external enclosures. For example, they may be used for external devices, such as keyboards, case fans, or mouse. Additionally, they may also be used for internal circuitry, such as cables that are used to connect motherboards and video cards, etc.

Regarding military/avionics interfaces, D-Sub Connectors are used mainly for control systems. For example, they may be used for signal and power connections between aircraft equipment and the main control panel. Specifically, they may be used to connect rudder pedals, flight instrument displays, GPS receivers, etc.

Working Principle

The working principle of a D-Sub Connector is fairly straightforward. Essentially, they are composed of two electrical connectors that join/connect two electrical components together. This results in the completion of an electrical path that allows for current to flow between two elements.

The actual contact between the two connectors is established via precision pins and sockets. The pins have a female or female connection type, depending on the application. The pin is then connected to a socket via a mechanical process that involves a low force, mechanical movement.

The completion of the contact between the pin and socket is then ensured by direct contact. In addition, the contact is made secure by an insulating collar or sleeve that prevents any kind of potential interference. This insulator also provides additional strain relief and protection from shock and vibration.

In summary, the working principle of a D-Sub Connector is that two metal connections join together, which complete an electrical circuit. This then allows for electricity to flow between two elements. The actual contact is secured by precision pins and sockets connected via a mechanical process and then further secured by an insulating collar or sleeve.
