Backplane Connectors are used to connect boards in a chassis such as computers, telecommunications equipment, industrial control systems, and so on. They are designed to transfer high speed signals with low-resistance and low-inductance connections. The 194189-3 contact, developed by 3M, is one such member of the Backplane Connectors family. This article discusses the application field and working principle of the 194189-3 contact.

Application Field

The 194189-3 contact is designed to be used with high-density printed circuit boards (PCBs). The contact’s design allows greater flexibility in the arrangement of the contact locations on the PCB. The contact offers the advantage of eliminating the need for complicated soldering and reworking operations. It also facilitates the assembly process by allowing quick removal and replacement of the contact itself.

The contact is compatible with a broad range of board designs, including single-ended and differential signals, high density and mid-density board layouts, as well as backplane designs. The contact is also specifically designed for high-frequency applications and blind mating, making it a perfect choice for many applications. With its robust design and high-density connection, the 194189-3 contact is an ideal choice for many industrial, telecommunications, military, and other environment-critical applications.

Working Principle

The 194189-3 contact is designed to provide a reliable connection between two boards, allowing for low-impedance, high-frequency signals transfer. The contact features a precision-moulded spring steel cantilever contact, with an optional crimp termination. The cantilever contact is designed to provide a strong engagement force between the connecting board and the contact itself, ensuring the high-speed signals are transferred with a low-resistance and low-inductance, thus minimizing the effect of reflections and crosstalk.

The contact itself is secured to the board via the press-fit design, which helps ensure that the contact does not move, shift or vibrate under shock or vibration. The contact is designed to be insertable and extractable hundreds of times without degradation of electrical performance, providing a reliable and effective connection over the full life of the product.

Conclusion

The 194189-3 contact is one of the most popular backplane connector contacts on the market today. It combines the advantages of a strong engagement force, a press-fit design and compliant and mechanical stability with a high-speed signal transfer and reliable connection. Its robust design and high-density connection make it an ideal choice for many industrial, telecommunications, military and other environment-critical applications. With its reliable connection, this contact provides a perfect solution for a wide range of applications.
