Overview
EN 3716-001:2006 - Aerospace series - Connector, single-way, with triaxial interface, for transmission of digital data (Part 001: Technical specification) defines the technical requirements for single-way triaxial connectors used for digital data transmission in aerospace applications. It applies to connectors mated with two‑core shielded cables per EN 3375‑003 / EN 3375‑004 / EN 3375‑005, supports frequencies up to 5 MHz, and covers a wide temperature class: −65 °C to 150 °C. The standard sets out design features, materials, mating dimensions, test programmes, qualification, acceptance and quality assurance.
Key topics and requirements
- Scope & interface: Single‑way triaxial interface connectors for digital data transmission using specified bifilar shielded cables.
- Mechanical design: Screw‑type coupling with mechanical end‑stop; insert non‑removable and retained mechanically; plug uses a knurled coupling ring; receptacle fixed with nut, anti‑vibration washer and gasket.
- Contact and materials:
- Contacts: solder or crimp type, copper alloy gold‑plated over an undercoat.
- Housing: copper alloy, tin‑plated. Corrosion protection required if dissimilar metals combine (electrochemical potential ≤ 0.25 V).
- Electrical performance:
- Usable up to 5 MHz for digital data.
- Low‑level contact resistance requirements (typical limits: ~35 mΩ initial, 40 mΩ after tests for central/intermediate contacts).
- Insulation resistance: ≥ 5 000 MΩ at ambient, ≥ 1 000 MΩ at 150 °C, ≥ 100 MΩ after tests (mated).
- Voltage proof: 900 V r.m.s. at sea level between central, intermediate and external conductors (reduced at altitude).
- Environmental & mechanical tests:
- Endurance at temperature: 1 000 h at 150 °C.
- Mechanical endurance: 500 mating cycles.
- Vibration and shock, salt mist, sand/dust and fluid resistance tests are specified; fluid types include aviation fuels, hydraulic fluids, synthetic lubricants and de‑icing fluids (see product table).
- Quality & qualification:
- Qualification per EN 9133 with defined test groups and sampling (generally two samples per group).
- Test programmes and acceptance criteria are detailed for design qualification and production lot acceptance.
Applications & users
- Typical users: aerospace OEMs, connector manufacturers, wiring‑harness designers, avionics engineers, test laboratories and procurement/quality teams specifying reliable triaxial connectors for aircraft data links.
- Practical uses: shielded single‑direction digital signal links in aircraft systems where controlled impedance, high shielding and environmental robustness are required.
