Backplane Connectors - ARINC Inserts

1. Overview

ARINC inserts for backplane connectors are modular interconnect solutions designed to meet aviation and high-reliability industry standards. Defined by ARINC (Aeronautical Radio Inc.) specifications, these connectors provide scalable, high-density electrical connections between printed circuit boards (PCBs) and backplanes. Their importance lies in enabling rapid system maintenance, hot-swapping capabilities, and robust signal integrity in mission-critical applications such as avionics, defense systems, and industrial automation.

2. Main Types & Functional Classification

Type	Function Features	Application Examples
ARINC 404	Rectangular sealed connectors, 12-100 contacts, environmental sealing	Commercial aircraft avionics racks
ARINC 407	Panel-mountable, quick-disconnect design, 15-124 contacts	Military radar systems
ARINC 600	High-density LRU modules, 128-512 contacts, EMI shielding	Modern flight control computers
ARINC 801	Fiber optic termini, single/multi-channel variants	High-speed data links in UAVs

3. Structure & Components

Typical ARINC insert assemblies consist of: - Housing: Anodized aluminum or composite materials with keying features - Contact Blocks: Modular inserts with precision-machined copper alloy contacts (gold-plated) - Latching Mechanism: Cam-driven or push-pull coupling systems - Environmental Seals: Silicone gaskets meeting IP67 ratings - EMI Shielding: Conductive elastomer gaskets and metallized coatings

4. Key Technical Specifications

Parameter	Value Range	Significance
Current Rating	1-15A per contact	Determines power handling capability
Contact Resistance	5m	Impacts signal integrity
Dielectric Withstanding Voltage	500-1500VAC	Safety insulation requirement
Vibration Resistance	20G-50G	Ensures stability in harsh environments
Temperature Range	-65 C to +200 C	Operational reliability factor

5. Application Areas

Aerospace: Boeing 787 flight management systems, Airbus A350 IFE backplanes
Defense: F-35 radar interface modules, naval combat management systems
Industrial: High-availability server racks, automated test equipment
Transportation: High-speed train control systems
