Backplane Connectors - ARINC Inserts

ARINC Inserts, with part number 446659-2, are an example of specialized backplane connectors. They employ a quick-disconnect style device that allows rapid system reconfigurations without having to disassemble the physical connections between closely spaced connections. This type of connector is commonly used in high-density interconnect applications such as aerospace systems, military avionics systems and industrial control systems. This style of backplane connector is designed to provide high-speed data transmission, low-profile designs, and high-reliability power connections.

The ARINC Insert 446659-2 is a standard differential, electrical, high-speed, two- or three-wire, low-profile, non-locking connector. It is used to mate a mother board and daughter board, or two cards in a backplane in high-density applications. Connector plugs feature a twist-lock mechanism that latches securely when fully engaged.

Because the connector is designed with differential signal pairs, it has signal isolation, allowing signals to be sent and received separately from one another. Differential pairs also provide a lower amplitude waveform that has reduced susceptibility to electromagnetic interference (EMI) or radio frequency interference (RFI). Each interface is capable of transmitting data at speeds up to 100 megabytes per second.

The 446659-2 ARINC Insert is designed so that it can be inserted or removed from a mating connector without the need to first unlock the mating connector. It is a compact connector that comes in two versions - either a two-position or three-position configuration. The two-position connector requires two mating components and provides two signal pairs (4 contacts in total). The three-position configuration requires three mating components and provides three signal pairs (6 contacts in total). It also offers a latch extender for greater accessibility during the insertion and removal process.

The 446659-2 ARINC Insert is tested to MIL-I-45208 military standards to ensure its performance in harsh environment applications. The insulation on the contact points and housing have a minimum thickness of 50 microns. The construction of the connector utilizes a zinc/aluminum chromate finish, using gold-plating over nickel-plating for the finish on the contact points. A strain relief is provided to ensure that the cable connections remain secure and free from physical stresses.

In conclusion, ARINC Inserts, with part number 446659-2, are specialized backplane connectors that are often used in high-density interconnect applications. They offer high-speed data transmission, low-profile designs, and high-reliability power connections. The connector is designed to be inserted and removed using a twist-lock mechanism that latches securely when fully engaged. The connector resists EMI and RFI and is tested to military standards to ensure its performance in harsh environments.
