Overview
The prEN 3660-062 standard, titled Aerospace series - Cable outlet accessories for circular and rectangular electrical and optical connectors - Part 062: Cable outlet, style K, 90°, for heat shrinkable boot, shielded, sealed, self locking - Product standard, is an essential specification developed by CEN. This standard defines the design and performance requirements for a specific range of cable outlets used in aerospace electrical and optical connector systems.
These cable outlets are characterized by their style K, 90-degree orientation, shielding capabilities, and self-locking (anti-rotational) mechanism. They are designed for use with heat shrinkable boots and metallic bands, ensuring secure cable termination under demanding environmental conditions common in aerospace applications.
The standard supports various temperature classes and plating options to meet diverse operational needs, enhancing the reliability and safety of aerospace electrical connections.
Key Topics
Product Scope and Use
The cable outlets covered by prEN 3660-062 accommodate overall shielding braid and individual cable shields, providing robust cable termination for aerospace connectors compliant with EN 3660-002. They facilitate the secure termination of heat shrinkable boots and metallic shield termination bands, enhancing EMI protection.Temperature Classes and Material Plating
The standard specifies multiple classes based on temperature range and surface treatments:- Class N: −65 °C to 200 °C, aluminium with nickel plating
- Class K: −65 °C to 260 °C, stainless steel, passivated
- Class W: −65 °C to 175 °C, cadmium-plated aluminium alloy (olive drab)
- Class T: −65 °C to 175 °C, aluminium with nickel PTFE plating
- Class Z: −65 °C to 175 °C, zinc-nickel plated aluminium alloy, non-reflective dark
- Class V: −65 °C to 175 °C, tin-zinc plated aluminium alloy, non-reflective grey
- Class D: −65 °C to 175 °C, tin-zinc plated aluminium alloy, non-reflective dark
Mechanical & Dimensional Specifications
Dimensions for shell sizes 09 to 25 are standardized, covering shell external diameters, threading, cable entry dimensions, and standard front interface layouts. The outlets are self-locking with a unique torque profile to resist rotational loosening during operation.Testing and Quality Assurance
The standard requires compliance with rigorous aerospace test methods as described in EN 2591 series, including visual examination, mechanical endurance, thermal cycling, shielding effectiveness, and fluid resistance. This guarantees performance consistency under harsh environmental conditions typical in aerospace.Environmental and Safety Compliance
prEN 3660-062 mandates zero hexavalent chromium compounds in surface treatments, addressing health and environmental concerns. The coating materials offer excellent corrosion resistance, meeting a 500-hour salt spray test and continuous operational temperature ranges.
Applications
Aerospace Electrical Systems
Designed primarily for aerospace circular and rectangular electrical and optical connectors, these cable outlets ensure reliable cable shielding termination and environmental sealing in aircraft, spacecraft, and related ground support equipment.High-Temperature and Harsh Environment Use
Suitable for applications requiring temperature resistance from −65 °C to 260 °C, the cable outlets support heat shrinkable boots and metallic bands, making them ideal for high vibration, temperature-extreme, and electromagnetic interference (EMI) sensitive environments.Shielding and EMI Protection
These accessories provide critical shielding continuity, reducing electromagnetic emissions and susceptibility in complex aerospace wiring harnesses, contributing to safer and more efficient aerospace vehicle operation.Connector Systems Integration
Compatible with connectors listed in EN 3660-002, they integrate seamlessly into aerospace electrical and optical connection systems, facilitating standardization and simplifying maintenance and assembly processes.
