Terminals - Turret Connectors

1. Overview

Turret Connectors are electrical interconnect solutions featuring cylindrical terminals with threaded posts for secure wire attachment. This screw-type connection mechanism allows reliable termination of stranded or solid wires without soldering. Their vibration-resistant design and high current-carrying capacity make them critical components in automotive, industrial, and aerospace systems requiring robust electrical connections.

2. Major Types and Functional Classification

TypeFunctional CharacteristicsApplication Examples
Single-Turret TerminalSingle threaded post with hexagonal driveAutomotive battery connections
Double-Turret TerminalDual independent threaded postsIndustrial control panels
Weatherproof TurretSealed housing with IP67 ratingMarine electrical systems
High-Temperature TerminalRated for 200 C continuous operationIndustrial ovens

3. Structure and Composition

Typical turret connectors consist of: - Conductive core (brass/copper alloy with gold/silver plating) - Insulating body (high-temperature nylon or PBT) - Threaded turret (M3-M8 metric sizes) - Locking mechanism (nylon insert or mechanical lock tab) - Mounting flange (steel with zinc coating)

4. Key Technical Parameters

ParameterTypical RangeImportance
Current Rating10-100ADefines power transmission capacity
Voltage Rating300-1000VDetermines insulation requirements
Contact Resistance<5m Impacts power efficiency
Insulation Resistance>10G Ensures electrical safety
Temperature Range-55 C to +200 CDefines operational environment
Durability100-5000 cyclesDetermines service life

5. Application Fields

  • Automotive: ECU connections, alternator terminals
  • Industrial: PLC systems, motor controllers
  • Aerospace: Avionics power distribution
  • Consumer: High-end audio amplifiers

6. Major Manufacturers and Products

DelphiAutomotive TerminalsTS16949 certified
3MIndustrial ConnectorsCorrosion-resistant plating

7. Selection Guidelines

Key considerations include: - Current/voltage requirements (select 20% above system needs) - Environmental conditions (temperature, vibration, moisture) - Space constraints (panel cutout dimensions) - Certification requirements (ISO 8092 for automotive) - Maintenance access (positioning for tool engagement) - Cost optimization (balance between precious metal content and conductivity needs)

8. Industry Trends

Current developments include: - Miniaturization for EV power electronics - Composite materials for weight reduction - Integrated sensors for condition monitoring - Lead-free plating technologies - Standardization through IEC 60352-3 updates
