The FX4BH-40P-1.27SV(71) Rectangular Connectors are part of a family of Arrays, Edge Type, Mezzanine (Board to Board) connectors. This precise type of connector is designed for specific applications, and its working principle serves a critical role in its respective operation. This article therefore provides an overview of its application field and its working principle.

The application field of the FX4BH-40P-1.27SV(71) Rectangular Connectors is varied, as it is applicable across a range of different electronic components and equipment. These connectors are commonly used with electronic components in commercial and military aircraft, as well as space vehicles. These particular connectors had previously been used for satellite purposes due to their ability to withstand the harsh temperatures and conditions found in outer space better than other types of connectors. Recently, they have been used for more terrestrial purposes such as automotive applications, including engine management and control systems. They have also been used increasingly with mobile phones, computers, and other consumer electronics due to their small size and robust design.

The FX4BH-40P-1.27SV(71) Rectangular Connectors use a pin and socket design for both power and signal connection and their terminal contact pitch is a mere 1.27mm. These connectors are visually characterized by their right-angle headers and receptacles, which are designed to be mated and installed through a selected printed circuit board (PCB) via press-fit contacts. The receptacles themselves can be secured either through soldering or through press fit.

When it comes to the working principle of the FX4BH-40P-1.27SV(71) Rectangular Connectors, it is based on the electrical connection of certain points or paths without soldering. This is also known as "cold" or contact welding. This principle relies on several elements working together: a pin, a socket, a spring contact, and an insertion force. When the terminal, which contains the pin and spring, is inserted into the mating socket, the spring contact is expanded in order to ensure proper contact is made. The spring contact inside the sandwich locking system follows the pin grooves in order to make the connection stand firm. At the same time, the insertion force keeps the pin in the middle of the socket. This ensures that contact between the two components is precisely correct.

Conclusively, the FX4BH-40P-1.27SV(71) Rectangular Connectors are widely used, with an extensive application field that covers many electronic components and equipment. Along with this, its working principle of cold welding offers a secure, dependable connection that stands up to the rigours of a wide range of applications.
