The connector is overheating. What's the reason for this?

Connector Current Abnormality Handling Principle

Current-Matched Optimization : Resolve overcurrent and poor contact issues through current derating, wire gauge matching and structural upgrade, ensuring electrical safety and stability.

Current Abnormality Troubleshooting & Solutions

Overcurrent & Contact Issues

Overcurrent Handling :
• Current exceeding rating (e.g., 15A for 4-core): Derate or replace with high-current model
Poor Contact Handling :
• Caused by insufficient torque/contact oxidation: Re-tighten / clean contacts
• Ensure reliable electrical connection

Wire Gauge & Multi-Core Load Issues

Wire Gauge Matching :
• Undersized wire (e.g., 0.5mm² for 13A): Match recommended gauge (1.5mm² for 13A)
Multi-Core Full Load :
• All cores at full load: Derate usage or select 5-core high-current version
• Avoid overload of connector core pins

Technical Note: Compliance with current rating, wire gauge matching and proper contact maintenance is critical to prevent overheating, contact damage and electrical failure of connectors in industrial applications.
