77311-102-34LF Application Field and Working Principle

The 77311-102-34LF is a type of rectangular connector header that is male-pin-compatible for a wide range of applications, ranging from the industrial and automotive industries to consumer electronics and audio/video media. This is a two-row, 34-pin header with a pitch of 2.0mm.

General Overview

These connectors feature an easy-to-use polarization which consists of three parts: a socket, a header, and a locking mechanism. These parts all work together to ensure that a plug is inserted correctly but remain secure after. This feature is particularly useful in high-vibration applications like automotive ones, where the female receptacle is firmly and reliably held to the header. The locking mechanism is built to withstand housings and backshells that make use of a preferred centerline.

Applications

These male pin headers can be used in a variety of applications, including consumer electronics, industrial equipment, and automotive systems. The 77311-102-34LF is perfect for applications that require a high-performance and reliable connection between components.The design of the header makes it suitable for processing exposed terminals like relays and switches, which eliminates the need for costly molded-in components. Furthermore, its small size also allows it to be used in smaller, hand-held applications, including cellphone phones, audio hardware, portable medical devices, and gaming consoles.

Working Principle

The 77311-102-34LF uses Male Pin technology to help ensure a strong and durable connection. Male Pin technology involves inserting a pin into a female receptacle, which is then held in place by spring-loaded contact points in the header. This prevents the pin from moving in either direction. This allows for a robust connection that can withstand high vibration and continuous shocks and jerking, making it suitable for a variety of applications.

The headers also feature a K-type locking feature, with two "wings" that fit into two separate holes along the sides of the receptacle. This ensures that the header is held firmly in place, and allows for a stronger connection than with more standard methods of locking.

Conclusion

The 77311-102-34LF is a two-row, 34-pin rectangular connector that can be used in a variety of applications, including consumer electronics, industrial equipment, and automotive systems. Its K-type locking feature and male pin technology ensure that a strong and reliable connection is made between components.
