D-Sub Connectors

D-sub connectors, also known as subminiature connectors, are one of the most commonly used types of electronic connectors in a variety of applications. D-sub connectors are available in a variety of shell sizes, shapes, contact arrangements, and genders. The 09551157621741 D-sub connector series is a popular choice for cost-sensitive applications, providing a reliable connection in a wide variety of electronic systems.

Types of D-Sub Connectors

D-sub connectors are categorized based on the number of shell positions, or poles. The most commonly used D-sub connectors are made up of two-to-nine positions. There are two types of D-sub connectors: standard (commercial grade) and high-density (military grade). The 09551157621741 D-sub series is a commercial grade connector available in various shell sizes.

Application Field

The 09551157621741 D-sub series provides an economical solution for a wide range of applications. The commercial-grade connectors are ideal for use in consumer and monitoring electronics, computers and peripherals, communication systems, audio/video equipment, and other miscellaneous applications. The addition of male mil spec-style body inserts and a variety of gold-plating options make the 09551157621741 series perfect for use in military and aerospace applications.

Working Principle

The 09551157621741 D-sub connectors are designed with a "V" notch on the connector shell and contact pins for a secure mechanical connection. The V-notch and contact pins ensure that the two halves of the connector are correctly aligned and that the contact pins are securely held in place. Additionally, the V-notch serves to protect the contact pins from being damaged during connection or removal.

The 09551157621741 D-sub series utilizes a three-point contact system for reliable electrical contact. The three-point contact system consists of an internal contact and two external contacts. The internal contact is designed with a slight arc which allows for 180-degree contact when mated. The two exterior contacts have a double-leaf spring design and a flat surface which results in a low insertion and extraction force. The three-point contact system ensures that all three contact points are fully engaged for reliable electrical contact.
