Inspect threaded locking status and retighten to rated torque (60 cNm) if loose; check anti-loosening structures for damage.
Measure insulation resistance (≥100MΩ at 500V) and contact continuity to ensure electrical performance meets specifications.
Inspect seal rings for wear/cracks and cable tail clamps for secure fixation; replace damaged components immediately.
Clean housing and contact pins with anhydrous ethanol; replace aged parts (seal rings, springs) to maintain reliability.
Technical Note: For connectors in harsh environments (high humidity/corrosion), shorten inspection intervals to monthly and keep maintenance records for traceability.
