Overview

EN 4165-016:2024 is a CEN product standard in the EN 4165 aerospace series that specifies the double oval chimney for accessory (1 per 2 modules) used with rectangular, modular electrical connectors rated for continuous operation at 175 °C. The document defines the form, marking and basic technical characteristics of the oval chimney accessory that interfaces with the connector accessory body (see EN 4165-014). It is intended for use across aerospace applications where high-temperature, modular rectangular connectors are employed.

Key topics and requirements

• Scope: Defines oval chimneys for accessories used in the EN 4165 family of rectangular modular electrical connectors at 175 °C continuous.
• Design and dimensions: Includes dimensional requirements (in millimetres) and a reference figure. Key published values include:
  • inside section minimum: 69.4 mm
  • another inside section: 190.6 mm
  • hexagonal clip diameter: Ø 0.6 mm ± 0.10 mm
  • mass: 4 g max
• Accessory class: Reference to class assignment according to EN 4165-002.
• Marking: Required marking on each oval chimney must include:
  • the identity block (designation per Clause 6),
  • date of manufacture (year-week),
  • manufacturer’s name or trademark.
• Normative references and technical spec: The standard relies on EN 4165-001 for overall technical specification and EN 4165-002 for performance/contact arrangements. The accessory body counterpart is specified in EN 4165-014.
• Terms and definitions: Aligned with EN 4165-001 terminology.

Applications and users

• Who uses this standard:
  • Connector and accessory manufacturers designing or producing EN 4165-series components.
  • Aerospace systems integrators specifying connector accessories for high-temperature environments (engines, heat-exposed avionics bays).
  • Procurement and quality teams ensuring part compliance and traceability via required marking.
  • Maintenance and repair organizations replacing accessory chimneys to the correct form, fit and marking requirements.
• Practical value:
  • Ensures interoperability of accessory chimneys across EN 4165 rectangular modular connectors.
  • Supports high-temperature reliability by standardizing geometry, mass and retaining features (hexagonal clip).
  • Simplifies certification and part traceability through standardized marking (identity block, manufacture date, trademark).

Related standards
