Introduction

DF3DZ-3P-2H(50) is a type of rectangular connector, also known as headers, male pins or card edge connectors. It has three pins and two circuits. It is designed to provide quick and reliable connections between different electronic components.

Application Field and Working Principle

Application Field

DF3DZ-3P-2H(50) rectangular connectors are ideal for applications where space is an issue. They are often used in industrial applications that require a reliable mechanical and electrical connection. Common applications include circuit boards, equipment enclosures, and other electronics.

Working Principle

The DF3DZ-3P-2H(50) rectangular connector works as a male terminal. Two pins, located on the bottom of the terminals, make direct contact with the mating female connectors. The other pin, located on the top, does not make direct contact with the female connectors. Instead, it completes a connection through mechanical contact with the internal insulation of the female connector. The overall contact force is critical to the reliability of the connection. If the force is too low, the connection may be unreliable and the electrical connection may be compromised.

The mating surface of the DF3DZ-3P-2H(50) connector includes a series of metal pins that make a mechanical connection with the corresponding female terminals. The force applied by the board-level lock mechanism is determined by the amount of torque applied to the individual pins. The more the pins are tightened, the tighter the connection becomes. This ensures a reliable connection and prevents connector disengagement due to vibration or thermal expansion of the components.

Conclusion

DF3DZ-3P-2H(50) rectangular connectors are ideal for applications that require reliability and space efficiency. They have three pins, two of which make direct contact with the female terminals, while the third is secured through mechanical contact with the internal insulation of the female connector. This ensures a reliable connection and prevents connector disengagement due to vibration or thermal expansion of the components.
