Working Principle

The 641120-3 consist of two parts: the header and the male pins. The header portion of the connector utilizes a connector body or housing to which the male pins are placed into and locked into place. The male pins connect with the female connector on the board, allowing for signal to move between the two parts of the connection.

The header portion is designed to ensure the male pins hold securely. It also helps to protect the electrical contacts and the solder joint against vibration and strain. It also provides for a wider range of working temperature and electrical resistance; helping to ensure the reliability of the connection over time.

The male pins, on the other hand, make direct contact with the female connection on the board. The pin profile is designed with a broad tip to increase contact pressure between the board and the pin holder and prevent electrical arcing and short circuits. The cross profile helps to provide an effective seal and to lock the male pins in place. Additionally, the pins are made with high-grade Copper Alloy material to promote superior current standards, enabling them to operate at high operating temperatures.

Conclusion

The 641120-3 is a rectangular connector with header and male pins, designed for making contact within electronic circuits. It is suitable for applications such as wire-to-board electrical connections, internal electronic device wiring, and circuit board layout. With its low-cost, high current capability and UL/CSA rated components, the 641120-3 is an appropriate interconnect solution for a variety of applications, including automotive, telecommunications and data communications, computer peripherals and industrial control systems.
