Circular connectors backshells and cable clamps are critical electromechanical components that ensure secure cable termination, strain relief, and environmental protection in connector systems. Backshells provide mechanical support and shielding for cable-connector junctions, while cable clamps offer strain relief by securing cables to panels or equipment. These components are essential in maintaining signal integrity, preventing mechanical failure, and meeting industry-specific environmental standards across aerospace, industrial automation, and medical device applications.
| Type | Function Features | Application Examples |
|---|---|---|
| Metal Backshells | EMI/RFI shielding, high durability, threaded coupling | Aerospace avionics systems |
| Plastic Backshells | Lightweight, corrosion-resistant, quick-install design | Industrial IoT sensors |
| 360 Cable Clamps | Full-circle compression, vibration resistance | Robotics joint actuators |
| Split-shell Clamps | Field-installable, adjustable diameter range | Marine communication systems |
| EMI Shielded Clamps | Integrated conductive gaskets, grounding contacts | Military radar equipment |
Typical backshell assembly consists of: - Housing (aluminum alloy or thermoplastic) - Cable entry port with sealing ring (IP67 rated) - Strain relief mechanism (serrated clamping ring) - EMI shielding fingers (for metallic versions) - Panel mounting threads (UNF or metric) Cable clamp structure includes: - Two-part housing (upper/lower halves) - Elastomer compression sleeve - Threaded locking screws - Cable contact surface (textured for grip) - Optional grounding tab
| Parameter | Value Range | Importance |
|---|---|---|
| Material Temperature Range | -55 C to +150 C | Operational reliability in extreme environments |
| IP Protection Rating | IP65-IP68 | Dust/water ingress prevention |
| Cable Diameter Range | 2-25mm | Compatibility with various cable sizes |
| Insertion Force | 0.5-5N | Impact on field installation efficiency |
| Shielding Effectiveness | 60-100dB | Signal integrity maintenance |
| Vibration Resistance | 10-2000Hz, 10G | Aerospace/military compliance |
| Manufacturer | Representative Product | Key Features |
|---|---|---|
| TE Connectivity | Duronic MS Backshell | Quick-disconnect, MIL-DTL-38999 compliant |
| Amphenol | Series 5000 Cable Clamp | Multi-cable capacity, IP68 rated |
| Molex | ToughCrimp Shielded Backshell | 10G EMI shielding, vibration proof |
| Weidm ller | PROFIBUS Cable Clamp | Fieldbus protocol optimized design |
Key selection criteria include: - Environmental factors (temperature, humidity, chemical exposure) - Cable geometry (diameter, jacket material) - Mechanical requirements (vibration, pull-out force) - EMI/RFI shielding needs - Installation constraints (tool access, maintenance frequency) - Compliance standards (MIL-SPEC, IEC 60529) Example: For offshore wind turbine sensors, select stainless steel backshells with IP68 clamps and neoprene sealing to withstand saltwater corrosion and mechanical shock.
Current development trends include: - Hybrid connectors integrating optical and electrical backshells - Additive manufacturing for custom cable clamp geometries - Smart clamps with embedded strain gauges for condition monitoring - Nano-coatings for enhanced corrosion resistance - Miniaturization for UAV and wearable medical device applications - Sustainability focus: Recyclable thermoplastic formulations
