ARINC is the acronym for Aeronautical Radio, Inc., an aerospace engineering company. ARINC backplane connectors are used in aerospace applications where reliability and reusability are critical. ARINC developed the specifications for the 1484620-1 backplane connectors, which are designed to provide a low-impedance connection in demanding aerospace applications. This article will discuss the application fields and working principle of the ARINC 1484620-1 backplane connectors.

The ARINC 1484620-1 backplane connector is designed to be used in a wide range of applications including but not limited to aircraft avionics, shipboard electronics, land mobile electronics, and commercial electronics systems. Applications in which the 1484620-1 backplane connectors are utilized can include control systems, data acquisition systems, display systems, mission computers, and navigation systems. These connectors offer high current handling, low impedance connections, and fast response times.

The 1484620-1 backplane connectors provide reliable performance in a variety of aerospace configurations. The ARINC connectors feature a floating contact design, which allows them to maintain a secure connection even when there is vibration in the environment. Additionally, the floating contact design allows multiple connectors to be interconnected in a single assembly, which reduces the overall weight and cost of the system.

The most common type of contact arrangement for the 1484620-1 backplane connectors is the D-Type configuration. This type of configuration offers up to 94 contacts per connector, which increases the potential for I/O flexibility. The contact points are arranged in parallel rows, which are connected to a printed circuit board (PCB) via metal contact pins. Each row is designed to have a higher pulse current rating than the other, which ensures robust performance.

The working principle of the ARINC 1484620-1 backplane connectors is relatively simple. The contact pins are inserted into the ports of the circuit board in order to establish electrical contact between the connectors and the PCB. When the electrical currents pass through the connectors, they cause the contacts to vibrate, creating a tight connection between them. This vibration is transferred to the PCB, causing a variety of changes in the signals that travel through it.

The ARINC 1484620-1 backplane connectors offer numerous benefits for aerospace applications. The connectors are designed to be lightweight and durable, making them ideal for use in demanding applications where low-current, high-speed electrical connections are required. Additionally, the connectors are designed to provide a low-impedance connection, which ensures accuracy and reliability. The contacts of the connectors are designed to be vibration-resistant, and they can provide up to 94 contacts per connector. Finally, the connectors are designed to be reusable, making them an economical choice for many aerospace applications.

In conclusion, ARINC backplane connectors, particularly the ARINC 1484620-1 connectors, are designed to offer high reliability and reusability for aerospace applications. The connectors feature a floating contact design, which allows them to remain secure even in the presence of vibration. The contact pins of the connectors are designed to provide up to 94 connections per connector, allowing for a higher degree of flexibility in terms of I/O. The working principle of the connectors involves vibration resistance and low-impedance connections, both of which are essential in ensuring integrity and accuracy in the systems they are used in. The connectors are also designed to be lightweight and durable, making them a cost-effective choice for aerospace applications.
