Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) come in a variety of forms and perform a wide range of functions in the electronic systems of today. Arrays, Edge Type and Mezzanine (Board to Board) Rectangular Connectors each serve a clear purpose and provide a secure connection between two electronic components. 3-1939756-6 is a great example of one of the many such connectors available on the market. This application field and its working principle are explored in this article.

Application Field for 3-1939756-6

3-1939756-6 is a Board to Board edge connector, and is typically used to connect two PCBs (Printed Circuit Boards), such as a backplane PCB and a daughter board. It is designed to provide a secure mechanical connection, and features a double row of 120 pins on a 2.5mm pitch. It is designed for use in applications where high pin-count connectors are required including backplane and mezzanine applications.

Working Principle of 3-1939756-6

The 3-1939756-6 employs a standard female header contact. This contact has an insulation displacement contact section, a spring contact section and a nose contact section. When the connector is inserted, the nose contact section contacts the corresponding male contact on the connected board. The insulation displacement contact section penetrates the insulation of the conductor, providing electrical connection and retention. The spring contact section then presses against the back of the conductor to make sure that the connection remains reliable and secure. The 3-1939756-6 is a low-profile design, with a stack height of only 1.4mm.

The 3-1939756-6 connector is also designed with ground and power lines that are integrated into the housing, and it is also designed with features that make installation easier, such as guide posts and locking cavities. These features aid in preventing misalignment during installation and ensuring a secure connection.

Conclusion

The 3-1939756-6 is a great example of one of the many Board to Board Edge Type connectors available on the market. It is designed for applications where high pin-count connectors are required, and it utilizes a standard female header contact to provide a secure mechanical connection. Its low profile design, integrated ground and power lines as well as features that facilitate installation make it an ideal choice for many applications.
