Overview

EN 3155-077:2019 is a CEN product standard in the aerospace series that specifies the characteristics, tests and tooling for female electrical contacts, type A, crimp, class R. It covers sizes 22, 20, 16, 12, 8 and 5 and is intended for use in elements of connection defined in EN 3155-002. The standard is to be used together with EN 3155-001 (technical specification) and references associated male contacts in EN 3155-076.

Key facts:

• Operating temperature range: −65 °C to 175 °C (class R)
• Body material: copper alloy; gold plating on appropriate undercoat (selective plating permitted)
• Color-coding for identification follows ISO 8843 (with a defined black band for size 5)
• Contact #22 derived from SAE AS39029-12 and intermateable with SAE AS39029-11

Key Topics and Requirements

• Dimensions and mass: detailed dimensional drawings and tabulated limits for all sizes (see figures and Table 1 of the standard).
• Marking and identification: colour bands and band-width rules for quick size identification.
• Material & surface treatment: copper-alloy bodies with specified gold plating thickness per EN 3155-001.
• Permissible cables: AWG equivalents and conductor sizes with rated currents (Table 3).
• Tooling: approved crimping tools per SAE-AS22520 and insertion/extraction tools per SAE-AS81969; TR 4874 guidance for applicable crimping tools.
• Crimping parameters and selector numbers: provided for qualification of crimp joints and tooling (Table 4).
• Test requirements: electrical, mechanical and environmental tests referenced to EN 3155-001 and EN 2591 test methods (contact resistance, endurance at 175 °C, climatic sequences, salt mist, vibration, etc.).
• Assembly and test fixturing: instructions for fitting contacts into EN 4644-series connectors for qualification tests.

Practical Applications and Users

This standard is essential for:

• Aerospace connector and contact manufacturers (product design, production and quality control)
• Aircraft OEMs and suppliers specifying connector components for wiring harnesses and modular rectangular connectors (EN 4644 series)
• Test laboratories and qualification engineers performing environmental and electrical validation of contacts and crimp joints
• Maintenance, repair and overhaul (MRO) providers selecting correct replacement contacts and tooling
  Practical uses include high-temperature and harsh-environment electrical connections in airframe, avionics and power distribution systems.

Related Standards

• EN 3155-001 (technical specification) - use together with EN 3155-077
• EN 3155-002 (contact list/utilization)
• EN 3155-076 (male contacts)
• EN 4644-series (connector product/technical specs)
