D-Sub Connectors, often referred to as D-Sub connectors, are the family of electrical connectors that use a D-shaped or rectangular chassis. Between the pins of the socket and the holes in the chassis is a solid plastic insulator with a metal contact spring. The pin count is usually matched between the socket and the connector-mounted plug. They are most often used in computer connections, networking, audio/video systems and communication systems.

The 208877-1 connector is a two-pound general purpose signal and power D-sub connector. It is available with either solder or crimp terminals, and features a secure locking system that wraps around host cabling or hardware.

The 208877-1 is composed of a metal body, which houses the terminals and holds the connector in place. A plastic insulating housing fits tightly inside the metal body and covers the inner contacts. This housing is then further sealed with a plastic cap, to prevent any dust, dirt, or moisture from entering the connector. The pin configuration of the 208877-1 is usually seen with a 3-pin, or 4-pin arrangement, although other pin sizes are available.

The 208877-1 connector is primarily used in applications requiring the mating of a male and female connector. This is popular in applications such as PCs and laptops, as well as many other devices requiring cable to cable or cable to board connections. It is also used in certain industrial applications, such as linear actuators and other electronic motors, as well as a variety of ruggedized communications equipment.

The working principle of the 208877-1 connector is simple. When two male and female connectors are brought together, the male connector contacts the female connector by sliding into its slots. The force created by the contact spring helps the male from slipping back out, provided the applied force is not more than 16 pounds. This ensures that the connection is maintained without any chances of disruption. To disconnect the connection, the force applied must be greater than the contact force, resulting in a disconnect.

In summary, the 208877-1 application field and working principle, is a two-pound general purpose signal and power D-sub connector. It is composed of a metal body, which houses the terminals, and a plastic insulating housing that covers the contacts. The connector is primarily used in applications requiring the mating of a male and female connector, and its working principle is simple. By the application of a force greater than 16 pounds, the connection can be released, and the connection maintained.
