Introduction

Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are one of the most important components used in electrical and electronic circuit design and assemblies. Edge Type, arrays and mezzanine connectors are designed to provide high-current and signal connection to and between printed circuit boards (PCBs). They are commonly used in a wide variety of consumer electronic, computer, industrial, medical, automotive, and military applications. The 1-1761614-3 is an example of a mezzanine connector that is designed to mate two PCBs together. In this article, we will discuss the application field and working principle of the 1-1761614-3 connector.

Application Field

The 1-1761614-3 mezzanine connector is often found in applications where its small size and high-current rating provide the best signal-to-power ratio. Commonly used in industrial, medical, and automotive applications, its small size allows it to be mounted in confined spaces, saving valuable board space. Additionally, its minimal ground inductance also makes it an excellent choice for high-speed applications.

Working Principle

The 1-1761614-3 mezzanine connector is a board-to-board connector that utilizes two low-profile and high-current dipole arrays to transfer power and signal between two PCBs. The connectors mate in the horizontal direction, thereby increasing the connection density and eliminating the need for additional board space. The arrays consist of two mating connectors, which each contain two polarized plates that alternately “spring-tension” and press against each other when the connectors are mated, creating a tight mechanical and electrical connection. Each plate is made of an electroplated high temperature alloy and the arrays are encased in reinforced plastic housing.

Conclusion

The 1-1761614-3 mezzanine connector is a versatile and small, board-to-board connector designed for high-current and signal transfer between two PCBs. The connectors mate in the horizontal direction, increasing connection density and eliminating the need for additional board space. Their low-profile and high-current design make them ideal for industrial, medical, and automotive applications. Furthermore, their minimal ground inductance allows them to be used in high-speed applications.
