Introduction

The DF9A-21P-1V(22) belongs to the family of rectangular connectors and arrays, edge type, mezzanine (board to board). It is a type of connector used to join or move two printed circuit boards (PCB) perpendicularly. It is a very versatile connector and is used in many devices all over the world. This article will look into the application fields and working principle of the DF9A-21P-1V(22) connector.

Application fields

The DF9A-21P-1V(22) is a versatile and reliable connector, making it suitable for a wide range of applications. With its insulated shielding, it can be used in almost any environment, from the extreme heat of the desert to the high humidity of the jungle. It can be used in automotive, consumer electronics, industrial electronics, medical, military, and aerospace applications. It can also be used in computer peripherals, radio frequency, and mixed signal connections.

Working Principle

The DF9A-21P-1V(22) is a two-piece connector that consists of a base (or main circuit board) and a daughter board (which acts as an extension of the base and is connected via the connector). It uses a standard edge connector geometry, which consists of two conductive rows of pins (male) and sockets (female).

The connectors are made from a high-temperature plastic material that has been designed to prevent heat damage during soldering, and with its tiny size it is portable, enabling easier connections. The contact pads on the pins and sockets are gold plated to ensure good electrical contact and high resistance to corrosion. The contacts are held in place using metal clips that lock them to the base and daughter board. The metal clips allow the contacts to be easily and securely released, enabling fast and reliable connections between two or more printed circuit boards.

Conclusion

The DF9A-21P-1V(22) is a high-quality and reliable rectangular connector array for board-to-board connections. It is suitable for a wide range of applications, from automotive to military, and provides a secure and reliable connection between two or more printed circuit boards. With its insulated shielding, tiny size, and high temperature plastic, the DF9A-21P-1V(22) is a versatile and reliable connector for any application.
