Rectangular Connectors are essential in connecting electronic components to form electrical and electronic subsystems. This makes them highly valuable components, especially when used with printed circuit boards (PCBs). This article presents an overview of the M20-7870442 connector, including its application field and working principle. It belongs to the category of rectangular connectors, namely headers, receptacles, and female sockets.

Application Field of M20-7870442 Connector

The M20-7870442 insulator is mainly used for the interconnection of printed circuit boards (PCBs). It is an air plugs and sockets connector, which also promises two-level connectivity. Utilizing a positive locking feature provides a stable base for a secure connection for use in a variety of environments. The M20-7870442 has a screw thread mount, which allows for mounting to a panel or PCB.

It is a type of rectangular connector or header, featuring a two-level connection. It is suitable for a connection of 12 to 24 volts DC circuits, with a two-piece, two-level connection. The connector provides excellent performance for a low-voltage application. It is highly reliable and designed for use in harsh environments. The M20-7870442 meets the IEC 60950-1 certification for safety and functionality.

Additionally, the M20-7870442 has a superior ability to resist corrosion. The gold plating process of the connector ensures that the contact terminals remain in good condition under high temperature and humid environments. Furthermore, it has a high dielectric strength between the contact points, ensuring good electrical insulation.

The Working Principle of M20-7870442 Connector

The M20-7870442 connector comprises a metal contact terminal fixed securely in a plastic insulator. It has pins on either side which correspond to the contact-terminal holes present on the printed circuit board. During the connection, a metal contact is inserted into both sides of the printed circuit board to connect the terminals. The metal contact is also encapsulated in the plastic insulator and fixed with a threaded screw.

The threaded screw offers a secure mounting onto the board and also ensures an uninterrupted connection to the contact points. This in turn guarantees that the connection is firm and secure, preventing any loose, weak, or defective connection. The connector is equipped with a sealant o-ring, which makes it highly effective in increasing the insulation performance.

The contact terminals have low contact resistance and offer superior current-carrying capacity. This enhances the efficiency of the electric system and prevents it from short-circuiting. In addition to this, the connector features gold plating which helps protect the contact points from corrosion and offers excellent solderability performance.

Conclusion

The M20-7870442 connector is a type of rectangular connector, belonging to the category of headers, receptacles, and female sockets. It is mainly used for the interconnection of printed circuit boards. It offers superior performance for a low-voltage application, with a two-piece, two-level connection. Additionally, it has a superior ability to resist corrosion and has a high dielectric strength between the contact points. Lastly, its contact terminals have low contact resistance, offering superior current-carrying capacity.
