Mechanical Interlocking is a safety mechanism that enforces operational sequence constraints through mechanical design, primarily utilized in industrial plugs and sockets (e.g., IEC 60309-compliant products) or other electrical connection systems. Its core function is to ensure that operations can only be performed under specific conditions, such as preventing live mating/demating, avoiding short circuits, or mitigating arc hazards caused by improper handling

Intrinsic Safety
Mechanical Enforcement: Relies on mechanical constraints rather than electrical controls or human compliance, fundamentally eliminating operational errors.
Typical Scenarios: Prevents power activation when the plug is not fully inserted; prohibits plug removal when the switch is in the "on" position.
High Reliability & Long Service Life
Robust Construction: Manufactured from high-strength engineering plastics (e.g., PA6), resistant to vibration, corrosion, and frequent operation in industrial environments.
Simplified Design: No complex electronic components, resulting in low maintenance requirements and minimal failure rates.
Intuitive Operation
Tactile & Visual Feedback: Provides clear operational status through tactile cues and visual indicators , reducing training costs.
Example: Automatic power connection upon rotational locking of the plug; automatic power disconnection upon reverse rotation and unlocking.
Compatibility & Standardization
International Compliance: Conforms to global standards (e.g., IEC 60309, GB/T 11918), compatible with industrial connectors of various voltage and current ratings.
Customizable Design: Tailored solutions available to meet specialized application requirements.
Structural design
Pin layout: Asymmetric design (such as 3P+E) is adopted to ensure the only insertion direction.
Sealing structure: Rubber sealing ring + thread locking to achieve double waterproofing.
Application Scenario
Heavy industry: port cranes, welding equipment, automated production lines.
Outdoor scenes: stage lighting, temporary power supply stations, new energy charging piles
