Rectangular Connectors - Headers, Male Pins - 77311-802-04LF application field and working principle

77311-802-04LF headers are versatile rectangular connectors used mainly to transfer electrical signals between a circuit board and other circuit boards, a wiring harness, or an electronic module. They are most common in consumer electronics, such as computers, cell phones, automobile electronic components, audio equipment, and home security systems.

Application fields

Headers are used in most consumer electronics to connect components to a circuit board, such as for a processor, memory, display, power supply, external ports, and other components. The ability to increase the speed of electronic communications facilitated by headers has been instrumental in the development of many consumer electronics applications.

77311-802-04LF headers are especially useful for specialized consumer electronics applications. For example, they are frequently used in medical devices, aviation control systems, robotics, automation, embedded systems, and in military and aerospace industries. In addition, they also have applications in communications, automotive, industrial, and instrumentation industries.

Working principle

77311-802-04LF headers are designed with two sets of pins. Each set has two contact points, with one contact point in the center and the other near the sides of its respective socket. The contact points are connected by a spring-loaded arm. The design of the contact points allow for a secure connection between the header and the circuit board.

The 77311-802-04LF header works by applying pressure from the spring-loaded arm to the contact points. As the arm is pushed against the contact points, a current is allowed to pass between the two. This current then passes through the circuit board, connecting the components on the board and, therefore, providing electrical signals to the components.

The 77311-802-04LF header also has a clip on the back that is used to secure the header to a circuit board. This clip ensures that the header stays secure in place and that the connection between the header and the circuit board is not interrupted.

Conclusion

Headers are essential components for consumer electronics applications, and the 77311-802-04LF header is a versatile rectangular connector that can be used to transfer electrical signals between a circuit board and other circuit boards, wire harnesses, or electronic modules. It is also commonly used in medical, aviation, and military/aerospace applications. The 77311-802-04LF header works by applying pressure from the spring-loaded arm to the contact points, which then allows a current to flow through the circuit board and provide electrical signals to the components. The clip also secures the header to the circuit board, ensuring that the connection remains secure.
