General Information
Overview
EN 3660-031:2017 is a CEN product standard in the Aerospace series that defines cable outlet accessories - style K, straight, shielded and sealed - for heat shrinkable boots. These backshell-style cable outlets are designed to terminate overall shielding braid or individual cable shields and to accommodate heat-shrink boots when used with memory metal rings (see EN 3660-034). The standard applies to use with the mating connectors listed in EN 3660-002 and is intended for aerospace electrical and optical connector systems.
Key topics and requirements
- Scope & purpose: Specification of dimensions, materials, finishes, tests and marking for style K straight cable outlets that provide shield termination and environmental sealing for heat-shrink boots.
- Temperature classes: Defined operating temperature ranges by class:
- Class N & K: −65 °C to 200 °C
- Classes W, T, Z: −65 °C to 175 °C (T = Nickel PTFE plating, Z = Zinc-Nickel plating)
- Mechanical & dimensional data: Detailed shell sizes, cable entry diameters, mass tables, and AS85049 interface dimensions (figures and tables in the document).
- Materials & finishes: Class-specific materials/finishes (e.g., aluminium with nickel, stainless steel passivated, cadmium plating, nickel PTFE, zinc-nickel).
- Manufacturing: Acceptable manufacturing processes include cast, fabricated or machined parts; internal surface finish requirement (max 1.6 µm) and no sharp internal burrs.
- Assembly torque: Installation torque limits are specified per shell size and class for safe assembly.
- Electromagnetic requirements: Shield termination performance criteria including housing continuity limits and surface transfer impedance / shielding effectiveness across 100 MHz–1 GHz.
- Environmental & mechanical tests: Qualification/testing per EN 2591-100 and EN 3660-001 covering IP67 sealing (IEC 60529), salt mist, fluid resistance (EN 3909), rapid temperature change, lightning strike pulses, vibration, shock, mechanical strength, endurance and tensile tests.
Applications and who uses it
- Aerospace electrical engineers specifying connector backshells for aircraft and space systems.
- Connector and cable-assembly manufacturers producing shielded, heat-shrinkable booted terminations.
- Qualification and test laboratories performing environmental, mechanical and EMC tests to aerospace standards.
- Procurement and quality assurance teams ensuring components meet standardized dimensions, finishes and performance for interoperability and safety.
