As new‑energy vehicles evolve toward higher voltage platforms and longer driving ranges, the vehicle’s thermal management system imposes stringent requirements on the electrical connection reliability of electric compressors. As a core conductive sealing component within the high‑voltage chamber, the compressor terminal directly determines the operational safety of the onboard air‑conditioning system throughout its entire lifecycle.
These products are subjected over long periods to continuous vibration from vehicle operation and alternating thermal cycling between day and night, while also enduring prolonged immersion in refrigerant–lubricant media. They must simultaneously deliver three critical performance attributes: stable high‑current conduction, robust insulation and sealing, and zero refrigerant leakage. At the material level, we optimize high‑temperature‑resistant conductive substrates and modified insulating encapsulants, employ an integrated high‑pressure sealing molding process, and tightly control microscopic sealing gaps. During manufacturing, we incorporate comprehensive reliability verification—including airtightness testing, high‑voltage withstand, vibration durability, and thermal‑cycling assessments—to mitigate risks of insulation degradation, medium leakage, and contact heating that may arise with extended service life.
From passenger cars to heavy-duty commercial vehicles, compressor power ratings vary significantly across vehicle segments, requiring supporting connection components that accommodate a wide range of voltage and current levels. Domestic supply‑chain solutions are continuously refined to enhance mold precision and batch-to‑batch consistency, steadily boosting automated mass‑production capabilities and reducing the likelihood of component failures in end‑use systems. Technological advances in high‑voltage connector components enable more efficient thermal management for the entire vehicle, improving overall energy efficiency and further strengthening the independent supply‑chain capacity of core components in the new‑energy vehicle sector.
