89009-119LF

Backplane connectors are highly specialized components in the PCB assembly process. Connecting two circuit boards together, they are essential to reliable and secure signal transmission and power delivery. The 89009-119LF, a product from the 8900 series, is an example of a specialized backplane connector acting as a connection interface between a PC board and a backplane.

The 89009-119LF is designed for applications such as consumer digital television, digital video recorder, security recording, and industrial products. For these applications, the connector is designed to provide failure-free connection and secure data transmission at rates up to 12.5 Gbps.

Working Principle

The 89009-119LF backplane connector utilizes a bowed rectangular plastic housing with various contact components in order to provide reliable and secure connection between two circuit boards. The contact components of the connector include both horizontal and vertical contact fingers

The horizontal contact fingers include both dual-beam contacts and thumb-screw contacts, while the vertical contact fingers are primarily made of copper. The dual-beam contacts are designed to maintain secure contact in the event of a lateral force is applied, while the thumb-screw contacts are designed to ensure a reliable connection with minimal lateral movement.

The connector also features an anti-overstress protection. This protection is provided through internal spring elements which limit the amount of force applied to the contact fingers. In this way, the connector is able to maintain a reliable connection without risking the potential damage to the components.

Finally, the 89009-119LF features a removable plastic cover for easy access and installation, a latch-lock mechanism for secure connection, and an ESD protection feature in order to protect the integrated circuits from potential damages due to electrostatic discharge.

Conclusion

The 89009-119LF is an excellent example of a specialized backplane connector utilized in the PCB assembly process. Designed for applications in consumer digital television, digital video recorder, security recording, and industrial products, the connector provides reliable and secure connection even under lateral forces or electrostatic discharge, making it an ideal choice for applications of this type.
