Why does poor insulation occur in cold-pressed wiring terminals?
创建于05.29
Insulation failure in cold-pressed terminals can stem from multiple factors related to materials, processing, and usage. Here are the main causes:
1. Material Quality Issues
- Substandard Insulation Materials
- Moisture Absorption
- Metal Core Exposure
2. Processing and Assembly Defects
- Improper Crimping
- Over-Crimping
- Contamination During Production
- Incorrect Terminal-Wire Matching
3. Environmental Factors
- High Humidity or Corrosive Atmospheres
- Extreme Temperatures
- Vibration and Mechanical Stress
4. Design Flaws
- Inadequate Insulation Clearance
- Incorrect Insulation Layer Thickness
5. Aging and Wear
- Thermal Aging
- Mechanical Wear
6. Testing and Quality Control Gaps
- Inadequate Insulation Resistance Testing
- Non-Compliance with Standards
Prevention and Solutions:
- Use high-quality, certified insulation materials with appropriate environmental ratings.
- Optimize crimping processes and tools to ensure consistent, defect-free connections.
- Implement strict quality control, including insulation resistance and voltage withstand tests.
- Select terminals that match wire gauges and application environments (e.g., moisture-resistant terminals for outdoor use).
- Regularly inspect and maintain terminals in high-stress environments to detect early signs of degradation.
By addressing these root causes, the risk of insulation failure in cold-pressed terminals can be significantly reduced, ensuring reliable and safe electrical connections.
