Overview - EN 3155-046:2007 (Aerospace series)
EN 3155-046:2007 is a CEN product standard for male electrical contacts (type A), double‑crimping, class S, intended for aerospace elements of connection. It defines the required characteristics, tests and tooling for contact 046 and is to be used together with EN 3155-001 (technical specification) and EN 3155-002 (list and utilization of contacts). The matching female contact is specified in EN 3155-047.
Key topics and technical requirements
- Scope and application: Male electrical contacts 046, type A, double crimping, class S for aerospace connector elements.
- Dimensions and mass: Dimensions and tolerances are given in millimetres (see the standard’s figure and tables for size codes and detailed geometry).
- Material and protective plating:
- Body: copper alloy.
- Plating: nickel undercoat with minimum gold thickness 1.27 µm; selective protection is not permitted.
- Permissible conductors and ratings:
- Typical data from the standard: conductor cross‑section 0.4 mm2 (AWG 22), insulation max ø 1.25 mm, rated test current 5 A.
- Cable preparation:
- Stripped length specified (example: 2.9 mm ± 0.3 mm for listed sizes).
- Tooling and handling:
- Crimping and extraction tooling shall conform to MIL‑DTL‑22520 and MIL‑I‑81969 (positioners and insertion/extraction tool references provided in the standard).
- Test programme: Tests referenced to EN 2591 and EN 3155-001 include:
- Visual and dimensional inspection
- Contact resistance (low level and at rated current)
- Voltage proof and insulation resistance
- Temperature endurance (e.g., 1 000 h at 200 °C)
- Mechanical endurance, shock, vibration
- Salt mist, fluid resistance
- Tensile strength of crimped connections and gauge insertion/extraction forces
Applications - who uses this standard
- Aerospace OEMs and suppliers specifying or manufacturing aerospace electrical contacts and connector assemblies.
- Connector designers, electrical engineers and procurement teams ensuring part conformity and interchangeability.
- Test laboratories and quality/inspection departments performing acceptance and environmental testing.
- Tooling suppliers and maintenance technicians selecting crimping and removal tools for AWG 22 size contacts.
