D-Sub, D-Shaped Connectors - Contacts.  D-Sub connectors, also called D-shapes, are a type of electrical connector that is typically used to connect two electronic components together. They are found in a variety of applications, such as computer equipment, automotive, and medical equipment.

The contacts of D-sub connectors are typically either pins or sockets, which are soldered into the respective printed circuit board (PCB). In addition, each connector consists of two parts: the shell, which holds the contacts, and the hood, which generally is screwed onto the shell to enclose the contacts. A wide variety of configurations are available for D-sub connectors, including various contact numbers, contact shapes, shell sizes, and contact arrangements.

The most common arrangement for a D-sub connector is the 9-pin configuration, which is often used for serial communication. Other popular types include 15-pin, 25-pin, and 37-pin configurations. The 1731120151 is a 25-pin type of D-sub connector.

Working Principle. D-sub connectors use the principle of compression and pressure to hold the contacts in place. The contacts are held together by a plastic insulator, which is held in place by two metal plates. The contacts are forced against the plates by a metal insert, which presses against the plate when it is tightened. This causes the contacts to stay in place.

The contact pins of a D-sub connector are typically made of stamped copper that is plated with either nickel or gold. This provides a good electrical conductivity and also improves the corrosion resistance of the connectors. Additionally, some D-sub connectors may have a plastic insulator sleeve, which helps to prevent shorts between contacts and increases the overall reliability of the connector.

Application field. D-sub connectors are widely used in a variety of applications due to their high reliability and low cost. They are often used for serial communication, computer and telecom equipment, audio/video equipment, automotive, and medical equipment. D-sub connectors are also popular for panel-mount applications, where they can be easily mounted in a panel. Additionally, they are often used for prototyping and in industrial and hobbyist applications.

The 1731120151 D-sub connector is a popular type of connector used in a variety of electronic applications. It is commonly found in audio/video equipment, medical devices, and for prototyping applications in industrial and hobbyist projects.
