D-Sub, D-Shaped Connectors - Backshells, Hoods

1. Overview

D-Subminiature (D-Sub) connectors are electrical connectors with a D-shaped metal shell, providing reliable signal transmission and mechanical protection. Backshells and hoods are critical components that secure cable connections, provide strain relief, and protect against electromagnetic interference (EMI) and environmental factors. These components are essential in industrial, telecommunications, and medical applications where signal integrity and durability are paramount.

2. Main Types and Functional Classification

TypeFunctional FeaturesApplication Examples
Standard BackshellsBasic strain relief and EMI shieldingIndustrial control systems
Panel-Mount BackshellsSecure connectors to panels or enclosuresTelecom rack equipment
EMI/RFI Shielded HoodsEnhanced shielding for high-frequency signalsMilitary communication devices
Cable Clamp BackshellsIntegrated cable clamping mechanismsFactory automation machinery
Weatherproof HoodsIP67-rated protection against moisture/dustOutdoor surveillance systems

3. Structure and Components

Typical backshells/hoods consist of: - Metal Shell: Aluminum or steel for EMI shielding and durability - Locking Mechanism: Screws, threaded couplings, or bayonet locks - Cable Entry: Threaded ports or clamping systems - Sealing Glands: Rubber gaskets for environmental protection - Mounting Features: Flanges or panel cutouts for secure installation

4. Key Technical Specifications

ParameterImportance
Shielding Effectiveness (100kHz-10GHz): 60-100dBMaintains signal integrity in high-noise environments
IP Rating (IP65-IP68)Determines protection against dust/water ingress
Operating Temperature: -55 C to +125 CEnsures reliability in extreme conditions
Vibration Resistance: 10-2000Hz, 10GPrevents disconnection in dynamic environments
Material Corrosion ResistanceExtends lifespan in industrial/chemical environments

5. Application Fields

  • Industrial Automation: PLCs, CNC machines, factory sensors
  • Telecommunications: Routers, base stations, fiber optic equipment
  • Medical Equipment: Imaging systems, patient monitors
  • Aerospace: Avionics, flight control systems
  • Railway: Signaling systems, onboard diagnostics

6. Leading Manufacturers and Products

ManufacturerRepresentative ProductKey Features
TE ConnectivityD-Sub Backshell 1-1417087-0EMI shielding, IP67 rated
Amphenol97-3107 SeriesPanel-mount with threaded coupling
Molex1055 SeriesIntegrated cable clamp, RoHS compliant
ITT CannonCDM BackshellMilitary-grade environmental protection

7. Selection Recommendations

Key considerations include: - Installation Type: Panel-mount vs. inline cable configurations - Environmental Demands: Temperature extremes, chemical exposure - Shielding Requirements: EMI levels in industrial vs. commercial settings - Mechanical Stress: Vibration levels in transportation applications - Compliance Standards: MIL-STD-810, IEC 60529 certifications

8. Industry Trends

Current development directions include: - Miniaturization while maintaining shielding performance - Integrated hybrid connectors for power/data transmission - Advanced materials (e.g., conductive polymers) for weight reduction - Smart backshells with built-in condition monitoring sensors - Increased adoption of IP67+ rated hoods in IoT edge devices
