Problems such as difficult insertion of automotive controller plugs, broken buckles, and even short circuits due to improper lubrication are mostly caused by choosing the wrong oil. To solve these problems, the lubricating oil must meet five core performances:
Lubricating performance: Smooth and effortless
Low friction coefficient: Reduces friction between metal pins and plastic sockets, avoiding pin wear. Qualified oil can reduce the insertion and extraction force by 40%;
Long-lasting lubrication: The lubricating film resists frequent insertion/extraction and vibration, and does not fail easily.
Electrical performance: Safe without interfering with signals
High insulation: Insulation resistance ≥10¹⁴Ω to prevent short circuits;
No impact on conductivity: Does not form an isolation layer on pins, ensuring stable current transmission.
Chemical stability: No corrosion or deterioration
Corrosion resistance: Does not corrode copper pins, swell rubber sealing rings, or embrittle plastic casings;
Oxidation resistance: Not easy to deteriorate under high temperature and high humidity. When placed at 120℃ for 300 hours, the performance attenuation is ≤5%.
Environmental adaptability: Suitable for all climates
High and low temperature resistance: Does not solidify at -40℃ and does not flow at 150℃, coping with extreme weather;
Waterproof and moisture-proof: Isolates rainwater and moisture to prevent pin rust.
Adhesion performance: Firm without falling off
Sticks to the plug surface like an "invisible coating", resists vibration and does not fall off, ensuring lubrication during each insertion and extraction.
Choose "special oil for automotive electrical systems" and avoid industrial general-purpose grease; request a material compatibility report; pay attention to temperature resistance (-40℃~150℃) and insulation data.
