Introduction

The 1218958-1 is a type of backplane connector developed for the ARINC standard. It is used in commercial and naval avionic systems to connect various boards and devices to each other, typically backplanes, cross-connects, or other board-level components. This backplane connector is a very robust and versatile interconnect, designed to help meet the high-speed and wideband requirements of today’s avionics systems. This article will provide an overview of the 1218958-1’s application field and working principle.

Application Field of the 1218958-1

The 1218958-1 is primarily used to connect backplanes, cross-connects and other board-level components in commercial and naval avionic systems. It is a type of backplane connector classified as "ARINC" (Avionics Instrumentation Connector), and is designed to meet the demanding needs of avionic applications. The 1218958-1 can be used in a wide variety of applications including data, voice and audio systems, avionics computers, and mission-critical communications links. It is also often used in space and military applications due to its robust design and performance characteristics.

Working Principle of the 1218958-1

The 1218958-1 is an ARINC-compliant backplane connector that uses a threaded design. This design allows the connector to be unscrewed from most backplanes and cross-connects. The connector features eight (8) individually insulated contacts, which are arranged in an alternating zig-zag pattern. These contacts are arranged in two rows - four in the top row and four in the bottom row. Power and signal signals are connected via the connector\'s two rows and directed as necessary. The connector\'s design allows it to deliver high-speed, low-loss, and wideband performance in demanding mission-critical applications.

The 1218958-1 is designed to meet the stringent requirements of ARINC. Its threaded design helps to provide superior EMI/RFI shielding, reduce transient interference, and provide a reliable interconnect solution. The connector is constructed out of a high-performance plastic material and features a reinforced metal insert to help reduce wear. It also features a gold-plated finish to ensure optimal electrical performance and long-term reliability.

Conclusion

The 1218958-1 is a type of backplane connector developed for the ARINC standard. It is primarily used to connect backplanes, cross-connects and other board-level components in commercial and naval avionic systems. The connector features a threaded design which allows it to be unscrewed from most backplanes and cross-connects. The 1218958-1 is designed to meet the stringent requirements of ARINC, and features a gold-plated finish to ensure optimal electrical performance and long-term reliability.
