D-Sub, D-Shaped Connectors - Backshells, Hoods and DB19678-7 Application Field and Working Principle

D-Sub, or D-shaped, connectors are a type of electrical connector usually used in computer or telecom applications. Characterized by the D-shaped metal shells, D-Sub connectors often consist of two or more female sockets and a male plug. D-Sub connectors can have a range of sizes (DB19678-7 being the most common) and pin configurations and may be male, female, or combined gender. This versatility makes DB19678-7 connectors a popular choice for a wide range of applications

Design and Construction

DB19678-7 connectors typically consist of plastic insulators, a metal shell, and metal pins or sockets. The plastic insulator contains the pin blocks, which consist of the pins or sockets. The metal shell covers the insulator to provide a mechanical and electrical connection. The backshell and hood are external components of the DB19678-7 connector and serve an important role in protecting the pins and maintaining good electrical contact.

Application Field

DB19678-7 connectors are used for various types of data transmission. From desktop computing to industrial equipment, they are versatile for a wide range of applications. For example, they are used in medical technology, system engineering, communications, and audio/visual systems.

Working Principle

To understand the working principle of DB19678-7 connectors, it is first necessary to understand the pin configuration. A DB19678-7 connector has 19 pins arranged in a D-shaped pattern. The pins are used to transmit electrical signals from one source to another. The backshell and hood protect the pins from dust and other contaminants that can interfere with the signal’s transmission.

In addition to the pins, the backshell and hood protect the cable which connects the DB19678-7 connector to the other equipment. The backshell and hood also protect the connection from physical damage and electromagnetic interference. The backshell and hood also provide a strain relief, meaning they keep the cable from being pulled and put too much strain on the pins. This helps to ensure that the connection is secured and maintains good electrical contact.

Conclusion

DB19678-7 connectors are an extremely versatile type of electrical connector. They are used in a variety of applications, from desktop computing to medical technology. The pins, backshell, and hood of the DB19678-7 connector are all important components in the connector’s working principle. Together, they help to ensure that the connection remains secure, that the signal is transmitted properly, and that the connection is protected from dust and other contaminants.
