Introduction

3-644764-2 is a type of rectangular connector and header, male pin which is mainly used in the electronics industry. This type of connector is designed to provide a reliable and secure connection between large components that require high speed and high frequency performance or in situations where there are restricted compartments that limit space available for fitting the components.

Application Field

The 3-644764-2 rectangular connectors and headers are mainly used for the following:

• Communication equipment - The 3-644764-2 rectangular connectors are mainly used in communication and network systems and devices, as they provide a reliable connection between Ethernet ports, and other communication devices.
• Computer components - The 3-644764-2 rectangular connectors are widely used in computer component connections, such as motherboards, memory cards and displays.
• Automotive electronics - The 3-644764-2 rectangular connectors are also used in automotive electronics, such as audio-visual systems, dashboard controls and electronic instrumentation.

Working Principle

The 3-644764-2 rectangular connectors and headers are usually put together by using a common finger-type connection or a compression type connection. The two pieces of the connector need to fit together mechanically and electrically; the pins and the sockets need to be in contact with each other and aligned perfectly to make the connection.The common finger-type connection involves the two pieces of the rectangular connector being pushed together; this causes the pins and sockets to properly mate, and the connection is then held together due to a locking mechanism.The compression type connection involves the two pieces of the rectangular connector being compressed together with a compression tool. The pins and the sockets are then properly mated and held together with a locking mechanism.

Conclusion

The 3-644764-2 rectangular connectors and headers provide a reliable and secure connection between components which require high speed and high frequency performance. These connectors are primarily used for communication equipment, computer components, and automotive electronics. The two pieces of the connector need to be fitted together mechani- cally and electrically by using either a common finger-type connection or a compression type connection.
