Circular Connectors - Backshells and Cable Clamps

1. Overview

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.

2. Main Types and Functional Classification

TypeFunction FeaturesApplication Examples
Metal BackshellsEMI/RFI shielding, high durability, threaded couplingAerospace avionics systems
Plastic BackshellsLightweight, corrosion-resistant, quick-install designIndustrial IoT sensors
360 Cable ClampsFull-circle compression, vibration resistanceRobotics joint actuators
Split-shell ClampsField-installable, adjustable diameter rangeMarine communication systems
EMI Shielded ClampsIntegrated conductive gaskets, grounding contactsMilitary radar equipment

3. Structure and Components

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

4. Key Technical Specifications

5. Application Fields

  • Aerospace: Flight control systems, satellite communication arrays
  • Medical: MRI scanners, patient monitoring equipment
  • Industrial: CNC machine cabling, factory automation sensors
  • Transportation: Rail signaling systems, EV battery connectors
  • Defense: Tactical radio systems, weapon guidance electronics

6. Leading Manufacturers and Products

MolexToughCrimp Shielded Backshell10G EMI shielding, vibration proof
Weidm llerPROFIBUS Cable ClampFieldbus protocol optimized design

7. Selection Recommendations

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.

8. Industry Trends

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
