Rectangular connectors, also known as headers, male pins, or right angle connectors, are used in a variety of electronic devices and equipment, from computers to cell phones, and are commonly used to connect printed circuit boards (PCBs). The 644631-2 connector is an example of a right angle connector, and can provide fast, reliable connections in a variety of applications. In this article, we\'ll explore the 644631-2 connector\'s application field and working principle.

Application Field

The 644631-2 connector is designed for use as a standard interface for printed circuit boards and front panels for applications such as power supplies, electronic equipment, industrial instruments, and more. It has a single row of up to 20 pins and is capable of withstanding up to 0.25A of current in any row, making it suitable for power distribution and control.

Due to its robust design, the 644631-2 is also resistant to shock, vibration, and moisture, making it suitable for use in more extreme environments. Additionally, the connector is compliant with a variety of industry standards, including RoHS and UL, and is available in several different colors to facilitate coding.

Working Principle

The 644631-2 connector utilizes the crimp and socket system, which involves two primary components: the driver and the crimp. The driver is a spring-loaded, typically plastic holder that contains a set of crimpers or pins, while the crimp is a metal sleeve that physically engages the pins within the driver. To make a connection, the driver is inserted into the connector body and then the crimp is crimped onto the wires. The crimp is then secured, typically with a locking mechanism, and the connection is complete.

Once a connection is established, it can be checked for integrity using a DMM (Digital Multi Meter). This is done by connecting the DMM probes to the wires that connect to the crimp and socket. The DMM then reads the continuity of the circuit, ensuring that it is connected correctly.

In addition, the 644631-2 includes a housing designed to ensure full insulation between the connectors, protecting internal components from external moisture and other environmental hazards. The housing also keeps the pins aligned and prevents shorts from occurring.

Conclusion

The 644631-2 connector is a reliable and robust right angle connector designed for use in a variety of applications. It is capable of withstanding up to 0.25A of current, is resistant to shock, vibration, and moisture, and is compliant with a variety of industry standards. Moreover, the connector utilizes the crimp and socket system for fast and reliable connections and includes a housing to ensure full insulation between the connectors.
