General Information
EN 3660-034:2017 - Memory Metal Rings for Aerospace Cable Screen Attachment
Overview
EN 3660-034:2017 is a European standard published by CEN that specifies requirements for memory metal rings, style Z, used in the aerospace industry for attaching cable screens to cable outlet accessories. These specialized components are designed for use with circular and rectangular electrical and optical connectors, providing a reliable and durable method for terminating cable shields.
This product standard complements other parts of the aerospace cable outlet accessory series, including EN 3660-002 which indexes mating connectors and applicable cable outlets.
Key Topics
Material Composition
- Rings are made from shape-memory alloy primarily consisting of nickel and titanium.
- The rings feature an insulating inner layer to work with resistance heating tools.
- Equipped with thermochromic paint indicators, two stripes on the outer surface change color when proper installation temperature is achieved, ensuring optimal attachment.
Design and Dimensions
- Available sizes and specific dimensional requirements are defined in the standard to suit a variety of cable screen diameters.
- Markings, including color-coded dots (red, blue), identify specific ring types suited for single or double layer screen terminations.
- The product design ensures strong mechanical performance and compatibility with heat-shrinkable and sealed cable outlets.
Testing and Qualification
- The rings must meet qualification criteria outlined in EN 3660-001.
- Applicable cable outlet accessories standards include EN 3660-031, 032, 035, and 066.
- The standard ensures consistent performance in high-demand aerospace environments, supporting resistance to temperature extremes and mechanical stresses.
Marking and Storage
- Packaging ensures damage-free shipping and limits bag/box temperature to a maximum of 50°C.
- Storage requirements specify cool, dry conditions without direct sunlight to preserve ring integrity.
Applications
EN 3660-034:2017 memory metal rings are essential components in aerospace electrical and optical connector assemblies where reliable screen termination is critical. Key applications include:
- Aircraft wiring systems where electromagnetic interference (EMI) shielding is required.
- Avionics equipment to ensure screen continuity and proper grounding.
- Spacecraft and satellite connectors requiring lightweight, high-performance components with temperature-resistant properties.
- Defense aerospace systems where connector reliability under extreme temperature and vibration conditions is essential.
These rings are specifically designed for use with circular and rectangular cable outlets, making them versatile across multiple aerospace connector types.
