Backplane connectors are used for the connection of data and power between circuit boards. ARINC (Aeronautical Radio, Inc.) has developed the 1484650-1 standard backplane connector in order to provide reliable and robust data and power connections in high shock and vibration environments. This connector is the industry standard and is often seen in military, aerospace, and industrial applications.

Connector Applications

The ARINC 1484650-1 standard is used in applications that require reliable and robust data and power connections in harsh environments, such as aerospace applications. These connectors are ideal for connecting circuit boards, as they have a very high mechanical strength and can be used in high shock and vibration environments. In addition, the connectors can be used in applications that require tight spacing, as they feature a low profile.

The ARINC 1484650-1 is also frequently used in high-frequency applications, such as in antennas, cellular base stations, and radios. These applications often require very reliable connections that can withstand the high frequency signals. The robust construction and high contact integrity of the ARINC 1484650-1 make it ideal for these applications.

The ARINC 1484650-1 is also commonly used in the medical industry for connecting patient monitoring devices, as well as other medical equipment. These connections must be reliable and robust, and the ARINC 1484650-1 provides that assurance.

Connector Construction

The ARINC 1484650-1 is a robustly constructed backplane connector, featuring an epoxy glass body and gold plated contact pins. The connector has an integral strain relief for mounting a strain relief plate or a cable. The connector also features a latching retention system that allows for quick and reliable connections. The two parts that make up the connector are connected via a unique twist-lock mechanism.

The ARINC 1484650-1 has a maximum of 400 pins and can support different cable types. The maximum diameter of the cable is 0.8mm and the maximum current capacity is 3.5A. The connector also features a positive latching system that ensures the connection is properly made. This latching mechanism also prevents the connector from coming loose during operation.

Connector Working Principle

The ARINC 1484650-1 backplane connector consists of two parts: a plug and a socket. The plug features an array of spring loaded pins that are inserted into the sockets. When the pins are inserted into the sockets, they make contact with the corresponding contacts in the socket, creating an electrical connection. As the pins are spring loaded, they remain firmly in the socket and require a pull force to remove them.

The latching mechanism ensures the connection between the plug and the socket is secure, and prevents the connector from loosening during operation. The latching mechanism works by the connectors being locked in the locked position when they are connected, and the connectors can only be unlocked if a specific force is applied to them. This ensures the connection is secure and prevents accidental disconnections.

The ARINC 1484650-1 is a robust and reliable backplane connector that can be used in a wide range of applications, and is especially well suited to use in harsh and high shock and vibration environments. The robust construction and unique latching system ensures the connections are secure and can withstand the high shock and vibration requirements.
