D-Sub Connectors

D-subminiature connectors, also known as D-sub connectors or DB connectors, are mostly used to provide a serial connection between two devices. They can also be used as a power, data, or video connector to transfer signals from one device to another. They are commonly used in consumer electronics, computer/peripheral and other electronic equipment, commonly used in computer and data communication equipment, consumer goods, automotive electronics, audiovisual equipment, robotics control systems, instrumentation and telecommunications applications. They are one of the most popular types of connectors and are characterized by their circular pins and elongated bases.

6817W2203L001 application field and working principle

The 6817W2203L001 is a D-sub connector that meets the requirements of MIL-C-39001/01, a military standard for circular connectors. It is designed to provide reliable interconnection of electrical and electronic equipment in hostile environments. With its 3-pin and 4-pin configurations, which include 3, 4 and 5 positions respectively, the 6817W2203L001 can be used for a variety of applications, including power, audio, data and control. With its hermetically sealed design, the 6817W2203L001 is particularly suitable for use in severe environmental conditions. The connector is constructed with a die-cast body, molded body inserts and a stamped and formed stamped terminal. The molded body inserts serve to provide additional strain relief and reduce contact pin stress during mating and unmating. The connector also features a unique external locking mechanism that provides positive mating of the connector halves under dynamic conditions.

The 6817W2203L001 is a co-axial contact type connector with a threaded pin body. The connector body is designed with an open front and a closed rear. The threads on the pin body provide the connection between the four unequal circular pins and the crimp terminals. To ensure reliable interconnection, the 6817W2203L001 features 4 pin numbers which are marked on the body for easy identification of both mating and unmating. The pins are also marked with a two-barrel system for coding, which helps reduce transmission errors and simplifies installation. The connector’s gold-plated contacts require a minimum of force to maintain a strong connection. The contacting forces between the two connecting pins are offset by spring washers, which help to maintain a constant contact force during high-vibration applications.
