2-1903978-1 Application Field and Working Principle

2-1903978-1 is a type of flat female connector for backplane communication. It is widely used in aviation, aerospace, military, and other critical industries.

The 2-1903978-1 connector is designed for quick and efficient wiring between two or more signal layers. The contact type of the two-layer contact part is frictional coaxial, and the contact type of the two-layer contact part is frictional (both can be insulated). Each backplane connection includes mating face frames and opening frames. The mating face frame has a cylindrical centerhole, while the opening frame is equipped with a corresponding cylindrical center peg. The two combined together form a secure connection. An interlock mechanism is employed to ensure the connector\'s durability and reliability. This interlock mechanism is designed to prevent the mating faces of the two parts from separating during vibration or shock.

The typical applications of 2-1903978-1 connector cover the connection between the printed circuit board and the hardware framework. The connection of between the circuit board and hardware frame is beneficial to the layout, signal transmission between circuits, and the fixation of components. The working principle of the 2-1903978-1 is that the frictional contact is established between the two layers of the contact part, so that the required electrical signals can be transmitted between the two. The electrical signals include data signals, mechanical signals, not limited to digital and analog signals, and the transmission capacities are related to the physical quantity of the contact part.

The major benefits of using 2-1903978-1 include electromagnetic compatibility (EMC), improved connection quality, noise suppression, and cross talk. This connector also provides excellent EMI and ESD protection. The connector is designed with vari-tilt features, which ensures that the friction contacts are properly aligned with the parts being connected. This feature helps to eliminate signal crosstalk and increase signal reliability. The overall design is compact in nature and reduces the cost and weight of the entire product.

By using 2-1903978-1 backplane connector, data transmission between two modules becomes easier and more efficient. It also facilitates the connection between the printed circuit board and the hardware framework, as well as the fixation of components. The durability and reliability of the connector are also ensured due to its interlock mechanism. The EMI and ESD protection, as well as the noise suppression features, further add to the quality of the connection.
