Overview

EN 3645-009:2019 is a European standard published by CEN, defining the product requirements for aerospace electrical connectors that are circular, scoop-proof, and use a triple start threaded coupling. This part specifically covers the receptacle with a round flange and jam nut mounting. It addresses key technical features including dimensions, materials, electrical, mechanical, and climatic characteristics for connectors operating continuously at temperatures of 175 °C or 200 °C.

The standard ensures compatibility and interchangeability with specified MIL-DTL-38999/24 connectors widely used in aerospace applications. It provides manufacturers and users with consistent guidelines for design, marking, and testing to guarantee safety, reliability, and performance of these critical components in aerospace electrical systems.

Key Topics

• Connector Type
  Circular, scoop-proof connectors with jam nut mounting and triple start threaded coupling designed for harsh aerospace environments.

• Operating Temperature
  Rated for continuous operation at either 175 °C or 200 °C, catering to high-temperature aerospace systems.

• Materials & Surface Finishes
  Various shell materials including cadmium-plated composite, aluminium alloys (cadmium-plated, zinc-nickel plated, nickel plated), passivated stainless steel, and nickel-fluorocarbon polymer plated aluminum. These materials offer corrosion resistance like salt spray durability from 500 to 2000 hours.

• Dimensional Specifications
  Detailed dimension tables for shell sizes 09 to 25, including panel cut-out requirements, flange dimensions, and thread sizes aligned with MIL-DTL-38999/24 standards.

• Design Models
  Different models (J, W, Z, F, M, K, T) each with specific materials, finishes, salt spray resistance, and temperature ratings to suit varied aerospace needs.

• Marking & Identification
  Clear marking protocols to ensure traceability and conformity, following EN 3645-001 guidelines.

• Associated Standards
  Interconnected with EN 3645-001, -002, -006, -008, -011, and -012 parts focusing on related plugs, protective covers, sealing plugs, and accessory components.

Applications

EN 3645-009 connectors are extensively used in aerospace electrical and electronic systems where secure and reliable connections are vital under extreme environmental conditions. Typical applications include:

• Aircraft Wiring Harnesses
  Ensures stable electrical connections in engines, avionics, and control systems exposed to high temperatures and mechanical stress.

• Defense Aerospace Systems
  Used in military aircraft where ruggedness, fluid resistance, and operational reliability directly affect mission success.

• Spacecraft Electrical Interfaces
  Suitable for spacecraft wiring due to its high temperature resistance and durability against corrosive environments.

• Harsh Environment Electronics
  Perfect for ground support and aerospace ground equipment requiring identical performance standards as airborne systems.

This standard facilitates the selection and procurement of connectors that meet stringent aerospace requirements, improving safety, maintenance efficiency, and system interoperability.

Related Standards

EN 3645-009 works together with several other standards in the Aerospace series to provide comprehensive coverage for circular connectors used in aerospace:

• EN 3645-001 - Technical specification for scoop-proof triple start threaded coupling connectors.
• EN 3645-002 - Performance specifications and contact arrangements.
• EN 3645-006 - Protective covers for receptacles.
• EN 3645-008 - Non-release plugs with grounding features.
• EN 3645-011 & EN 3645-012 - Lanyard release plugs with grounding fingers.
• MIL-DTL-38999/24 - U.S. military specification for similar jam nut mounting connectors.

By adhering to EN 3645-009 alongside these related standards, manufacturers and engineers ensure interoperability and high quality in aerospace electrical connector systems, suitable for global deployment and conformance to national aerospace regulations.
