09692009147 connectors, also known as D-sub connectors or D-subminiature connectors, are a type of electrical power connector commonly used in a variety of electronic devices. These small, black connectors have two rows of nine to fifteen pins that are arranged in a symmetrical, dual-row arrangement. This design makes them easy to install, as well as providing a firm connection.

D-sub connectors are mainly used in the following fields:

• Computer and network applications, including peripherals, video, and audio devices
• Wireless telecommunication connects, such as cellular phones and PDAs
• Consumer electronics, including LCD TVs, digital cameras, and gaming devices
• Industrial, automotive, and medical equipments
• Audio-video production labs

The pins of a D-sub connector are typically arranged in a two rows, with the two rows offset from each other by 45 degrees, creating a “D” shape. The offset arrangement helps prevent accidental contact between pins on adjacent rows, safeguarding against short circuits. On the back side of the connector, each pin is soldered onto a stamped piece of metal called a “termination board.”

D-sub connectors are typically made of plastic and metal, with the inner metal pins made of steel or bronze. The steel pins are more corrosion-resistant and can provide stronger electrical signals, while the bronze pins may be used in environments where all signals must be kept within a specified voltage. The plastic parts are usually made of diallyl phthalate (DAP).

The working principle behind D-sub connectors is relatively simple. When two male and female connectors are mated together, the pins on the male connector slide into the slots on the female connector, making a secure metal-to-metal contact. This contact provides the full strength of the electrical connection.

D-sub connectors are a reliable and affordable option used in a variety of applications. With their two-row design, they offer a secure connection and are relatively easy to install. Their robust construction and versatile design make them an ideal choice for a range of devices.
