D-Sub, D-Shaped Connectors - Housings

D-sub connectors, also referred to as D-shaped connectors, are a common type of electrical connector. This type of connector is usually shaped like a half-circle, with pins or sockets at one end and a mating connector at the other. D-sub connectors are usually made of either metal or plastic, and each connector type is designed for a specific application.

The most commonly used D-sub connectors are the D-type connectors, which are used in many electronic applications. The basic design of a D-type connector is a metal or plastic body with two or more rectangular metal contact terminals. The terminals are designed to fit into a mating connector at the other end, thus creating an electrical connection. The contacts on a D-sub connector come in two types: female (socket) and male (pin). They are also available in several different sizes and configurations.

The D-sub connector housings are available in several different styles. The most popular styles include all-metal, solid-plastic, press-fit, and PCB-mount housings. The all-metal housings are typically made of stainless steel or aluminum, and are designed for use in more rugged environments. The solid-plastic housings are usually die-cast or injection molded and often come with a built-in strain relief device. The press-fit housings are designed to be installed by simply pressing the pin and socket together. Finally, the PCB-mount housings are designed to be mounted directly onto a printed circuit board (PCB).

The most common type of D-sub connector is the D-type 9 connector, which is used in many computer and telecommunications applications. This type of connector uses nine contact pins and has nine mating connectors. This type of connector is also available in a variety of sizes and configurations, including single-row, double-row, and stacked versions.

D-sub connectors are used extensively in many different industries, from automotive to aerospace. They are often chosen for their low cost and reliability. For example, in the automotive industry, they are used to connect signals between the engine, transmission, and other components, as well as to provide power for vehicle electronics. In the aerospace industry, they are often used to carry signals between flight control systems and other electronics.

The working principle of a D-sub connector is fairly straightforward. To make a connection, the pins or sockets of the connector are inserted into the respective mating connector at the other end. Once the pins or sockets are inserted, the connection is completed and an electrical circuit is formed.

In sum, D-sub connectors are a very popular type of electrical connector. They are available in many different sizes and configurations, and are suitable for use in a wide variety of applications. Their simple design and reliable performance make them ideal for many industrial applications, including automotive, aerospace, and telecommunications.
