GVA Series 30A 2-Pin High Voltage Plastic Connector

1. Poor Electrical Contact: This failure mode can be evaluated through static contact resistance, dynamic contact resistance, single-terminal separation force, and vibration endurance of contact interfaces and electronic components.
2. Insulation Degradation: Insulation performance can be assessed by measuring insulation resistance, insulation aging rate over time, and dimensional stability of insulation and contact components.
3. Mechanical Loosening or Detachment: Mechanical reliability can be verified by evaluating terminal and connector assembly tolerances, torque resistance, terminal retention force, insertion force, and retention performance under environmental stress conditions.

Recommended Design Measures to Improve Connector Reliability

• Rational Connector Selection: Connector selection should consider both circuit configuration and system integration requirements. Circular connectors are generally less sensitive to environmental and mechanical stresses than rectangular connectors, exhibit lower mechanical wear, and provide more reliable wire termination. Therefore, circular connector designs are often preferred where applicable.
• Optimization of Contact Quantity: A higher number of contacts typically results in lower overall system reliability. When space and weight constraints allow, it is recommended to select connectors with fewer contact points to minimize failure risk.
• Adaptation to Operating Conditions: Connector selection must account for actual operating environments, as rated current is determined based on maximum ambient temperature and allowable thermal dissipation. To reduce operating temperature and improve longevity, thermal management and heat dissipation should be optimized, for example by positioning power contacts farther from the connector center.
• Enhanced Waterproofing & Corrosion Protection: In environments with corrosive gases or liquids, protective measures must be implemented to prevent corrosion and contamination. Horizontal side mounting is recommended whenever possible. If vertical installation is required, liquid ingress through wiring must be prevented, and sealed or waterproof connector designs are strongly recommended.
