Overview

EN 3646-006:2018 is a European Standard established by CEN that specifies the requirements for hermetic jam-nut mounted receptacles in the aerospace electrical connector series. These connectors feature a circular, bayonet coupling design and are engineered to operate continuously at elevated temperatures of 175 °C or 200 °C. The standard addresses models designed for extreme environments, supporting operating temperature ranges from –65 °C up to 200 °C. This product standard is part of a broader series of standards that define components like plugs and protective covers within the same connector family.

Key Topics

  • Hermetic Jam-Nut Mounted Receptacles: This standard defines dimensional, material, and performance characteristics tailored for receptacles using a jam-nut mounting style ensuring high reliability in aerospace applications.

  • Operating Temperature Range: Designed to function under continuous temperatures of 175 °C or 200 °C, making them suitable for high-temperature aerospace environments.

  • Physical Dimensions and Tolerances: Detailed specifications for housing sizes, panel cut-outs, and attachment nut torque are provided to guarantee precise fit and secure connections.

  • Material and Surface Treatment: Typically featuring passivated stainless steel housings with solder contacts, selected for durability and resistance to harsh aerospace conditions.

  • Marking and Designation: Clear guidance on manufacturer marking, including part numbers, manufacturing dates, and trademarks, assists in traceability and quality assurance.

  • Model Scope: Covers hermetic receptacles (model Y), with temperature and material requirements for aerospace-grade connectors.

  • Normative References: The standard references related aerospace connector standards such as EN 3646-001 (technical specification), EN 3646-002 (performance and contact arrangements), EN 3646-008 (plugs), and EN 3646-009 (protective covers) for comprehensive compatibility.

Applications

EN 3646-006 connectors are primarily used in aerospace industry electrical systems where reliable, hermetically sealed electrical connections are critical under extreme temperature conditions. Typical applications include:

  • Aircraft electrical wiring systems requiring high-performance circular connectors.
  • Avionics and defense equipment exposed to high continuous operating temperatures.
  • Environments demanding resistance to harsh conditions such as vibration, thermal cycles, and potential contamination.
  • Systems mandating secure and leak-proof connections to maintain pressure integrity and insulation.

The bayonet coupling design enables quick and secure mating while the hermetic seal prevents ingress of moisture, dust, and gases, ensuring longevity and safety in critical aerospace missions.

Related Standards

EN 3646-006:2018 is part of a comprehensive aerospace connector series providing standardized solutions:

  • EN 3646-001: Technical specification for electrical circular bayonet coupling connectors operating up to 200 °C.
  • EN 3646-002: Specification of performance requirements and contact arrangements for the connectors.
  • EN 3646-008: Product standard for plugs compatible with the hermetic receptacles defined in EN 3646-006.
  • EN 3646-009: Specifications for protective covers designed to shield receptacles.
  • ISO 3161: Aerospace standard for UNJ threads, used for nut fittings in connector assemblies.

Compliance with these interconnected standards ensures full interoperability, safety, and quality in aerospace electrical connector applications operating under demanding conditions.
