Common Causes of Connector Failures
Loose or improperly tightened locking nuts
Contamination and corrosion
Improper cable preparation
Excessive bending radius and mechanical strain
Thermal and electrical stress
From pv-magazine USA: field tests showed frequent failures due to tight cable bends, dirt inside connectors, and loose locking nuts.
From Keyence: microscopic analysis revealed oxidation, solder/crimp defects, and metal migration as key failure factors.
Proven Solutions & Preventive Measures
Use torque wrench to ensure locking nuts are properly tightened
Clean all contacts before assembly, keep seals in place
Respect cable bend radius and apply strain relief
Use correct wire stripping length, soldering or crimping tools
Match current rating and connector spec to operating conditions
