Rectangular Connectors - Headers, Receptacles, Female Sockets are commonly used in electrical systems and have a wide range of applications. Among them, the 71991-445LF is a versatile, user-friendly, and reliable connector. This article introduces the application field and working principle of the 71991-445LF.

Application Field

The 71991-445LF is a 4.2mm pitch header receptacle with standard straight mating with different row number varieties. It is designed for high-density signal and power connections and is widely used in cellular phone, digital cameras, and other computer peripherals. Because it has an anti-reflection mating, optimal EMI and RFI shielding properties, and excellent signal integrity, the 71991-445LF is the optimal choice for high-reliability applications in the automotive, industrial and medical sectors.

The 71991-445LF features a symmetrical, double sided, horizontal mixed contact pattern that ensures secure and reliable mating. Its secure, six-finger board engagement provides high pulling resistance and ensures secure connections in challenging environment. Additionally, the 71991-445LF comes with an operating temperature of up to -40°C to 105°C and working voltage of 150VAC.

Working Principle

The 71991-445LF is a sophisticated electronic device that is designed to ensure reliable connections between two devices. It uses a series of contacts and an insulating shell to create an electrical and mechanical connection between the two devices. The contacts are arranged in two rows, with one row being contact pins, and the other contact pins being soldered onto the circuit board.

When two devices are connected using the 71991-445LF, they form a secure electrical circuit which ensures safe and efficient transmission of data. In order to form this circuit, the contacts must be secure and aligned correctly. The pins that are soldered to the circuit board ensure a reliable connection, while the contact pins are pushed into the female receptacle so that they make contact with the pin sockets inside the receptacle.

In order to ensure reliable connections and a secure electrical circuit, the components of the 71991-445LF must be high quality. The contacts are usually made from brass or gold plated wire, and have a spring loaded design which ensures that the contacts remain in contact with the pin sockets. The contacts are also designed to enable electrical signals to travel between devices without any interference or distortion.

Conclusion

The 71991-445LF is a reliable and versatile rectangular connector designed for high-density signal and power connections. Its symmetrical, double sided, horizontal mixed contact pattern, secure six-finger board engagement, and anti-reflection mating enables secure connections in challenging circumstances. This connector is suitable for automotive, industrial and medical sectors.
