General Information
Overview
EN 3155-052:2007 is a European standard developed by the European Committee for Standardization (CEN) that defines the product requirements for male electrical contacts used in aerospace connection elements. Specifically, it applies to electrical contacts identified as male 052, type A, crimp, class S, which are essential components in aerospace electrical systems. The standard ensures these contacts meet rigorous performance, dimensional, and material criteria critical for reliable aerospace electrical connections.
This standard must be applied alongside EN 3155-001, which covers technical specifications, and relates to EN 3155-002 for element utilization and EN 3155-053, which specifies associated female contacts. It establishes norms for characteristics, testing protocols, and marking to guarantee compatibility and safety in aerospace electrical equipment.
Key Topics
Dimensions and Mass: Contacts are governed by specified maximum mass (90 g) and precise dimensions after plating to ensure mechanical compatibility in aerospace connectors.
Material and Surface Treatment: Contacts are manufactured from copper alloys with gold plating over an appropriate undercoat to optimize conductivity, corrosion resistance, and durability.
Permissible Cables: Defined cable sizes and conductor types compatible with the contact barrels are provided, referencing EN 2083 for copper alloy conductor standards.
Tooling Specifications: Suitable crimping tools and dies (e.g., EN 4008-016) tailored to the contact and barrel sizes are detailed to ensure reliable crimped terminations.
Cable Preparation: Required cable stripping lengths are specified for different cable sizes to maintain consistent and secure electrical connections.
Comprehensive Testing: The standard mandates a suite of mechanical, electrical, and environmental tests based on EN 2591 series and EUROCAE-ED-14E procedures including:
- Contact resistance at low and rated currents
- Voltage proof and insulation resistance tests
- Temperature rise under load
- Endurance under high temperature and mechanical vibration
- Mechanical endurance and tensile strength of crimps
- Resistance to salt mist, fluids, and rapid temperature changes
Marking and Identification: Standardized marking practices for traceability including manufacturer identification and contact coding.
Applications
EN 3155-052:2007 contacts are specifically designed for aerospace electrical systems where reliability and high performance are crucial. Typical applications include:
- Aircraft wiring harnesses and interconnection elements
- Avionics equipment requiring secure and stable electrical contacts
- Critical aerospace systems where vibration, temperature extremes, and electrical loads impose stringent durability requirements
- Environments demanding compliance with aerospace industry standards for electrical connectors
Using these standardized male crimp contacts enhances system safety, ensures interoperability between manufacturers, and simplifies maintenance and replacement.
