Lead-In/Lead-Through Insulators TRIZ Cases
- Air-Cooled Through-Wall Bushing Using Pressure-Driven Ventilation
A pressure difference across the wall drives cooling air through the bushing channel, improving heat removal near current limits without fans.
- Crystallized Glass Joint Structure for Exhaust Insulation Stability
A crystallized glass joint extends creepage distance and limits porosity to maintain electrical insulation under exhaust heat and moisture.
- Branch-Covering Grommet Structure for Easier Wire Harness Winding
Multi-directional winding pieces and cutouts reduce tape winding effort on small-diameter wire harness branches while maintaining sealing and sound insulation.
- Composite Electrical Bushing Insulation for Contamination Resistance
A thermoplastic bushing with a chemically bonded elastomer cover improves hydrophobic insulation while reducing material use and breakdown risk.
- Composite Bushing Structure for Creepage and Contamination Control
A thermoplastic core with a silicone elastomer cover extends creepage length and resists contamination in liquid-insulated bushings.
- Liquid-Insulated Bushing With Internal Ribs for Leakage Control
Internal reinforcing ribs and a thermoplastic body cut material use while improving insulation, leakage resistance, and cleanability.
- Removable Bushing Flange With Localized Chamfer Filling
Localized filler in a sealed chamfer space secures a bushing flange while allowing removal and reuse despite core diameter variation.
- Pass-Through Element Protector Structure for Hidden Wire Damage Prevention
A metal casting and slotted plate enclose hidden wires or pipes in walls to block damage from later drilling or fastener insertion.
- Pass-Through Element Protector With Embedded Teeth Fastening
A metal enclosure with a toothed end plate protects hidden wires and pipes by anchoring into wall supports before drywall conceals them.
- Pressure-Driven Ventilation in Air-to-Air Bushings for Cooling
A wall pressure difference drives airflow through a bushing channel, improving cooling near current limits without fans or compressors.
- High-Voltage Feedthrough Electrode Layout for Compact Field Control
Axially extended electrode elements shift potential and equalize fields, shortening high-voltage feedthrough insulation while cutting weight and stress.
- Pt-Ni Hermetic Feedthrough Seals for CTE Stress Control
A Pt-Ni pin alloy and tailored glass-ceramic sealing profile balance CTE and compressive stress to prevent cracking and preserve hermeticity.
- Insulator Shed Tip Curvature to Reduce Corona Discharge
A non-circular shed tip with a larger end radius lowers electric field intensity, helping prevent corona discharge without added material cost.
- Modular Cable Feedthrough Sealing for Vibration-Secure Mounting
A threaded locking feedthrough secures modular cable seals in separating elements, improving adaptability and mounting stability under vibration.
- Feedthrough Insulator Field Control for Clean-Air Dielectric Strength
Field-controlling coatings or admixtures reshape the electric field in feedthrough insulators, raising dielectric strength in clean air.
- Wire Connector With Central Tab And Ribs For Multi-Cable Grip
A wire connector uses a hinged central tab and interior ribs to grip cables securely without damaging insulation.
