Frequently Asking Questions (FAQ)

Q1: How does your 2-pin HV connector prevent terminal ablation and arc flash risks under long-term high-voltage operation?

A1: Terminal overheating and ablation are critical points for low-current HV connectors, often caused by loose secondary locking or contact degradation under vehicle vibration, our connector terminal connector features a robust High Voltage Interlock (HVIL) option and custom-engineered crown spring terminals. This dual-safeguard design maximizes the electrical contact surface area, reduces contact resistance to ≤ 0.5 ohms, and inherently eliminates the risk of arc flashes and thermal runaway during hot-plugging or harsh vehicle shaking.

Q2: For high-vibration applications like EV compressors and PTC heaters, how do you ensure the IP67/IP6K9K waterproof seal doesn’t degrade over time?

A2: Many standard connectors fail field waterproofing tests after 1-2 years due to the thermal aging and mechanical compression set of standard rubber rings. We solve this by using premium Fluorosilicone (FVMQ) rubber seals instead of generic silicone. It offers exceptional resistance to automotive oils, coolants, and a wide temperature range (-40°C to 125°C), and with our rugged positive locking lever, the connector maintains an airtight IP67/IP6K9K rating even under continuous 3G-level automotive vibration profiles.

Q3: Many connectors suffer from loose mating or housing cracks due to UV exposure and high temperatures, how can we address this?

A3: Plastic degradation under the hood is a major quality issue. Our connector housings are molded from automotive-grade PA66+GF30 (30% Glass Fiber Reinforced Nylon) with advanced anti-UV and flame-retardant (UL94 V-0) additives. This material ensures high impact strength and zero dimensional distortion under severe high/low temperature cycles, preventing the locking tabs from snapping or becoming brittle during field servicing.

Q4: Do you accept OEM/ODM Services and sample evaluation before the mass production?

A4: Sure, of course, we accept OEM/ODM customized, sample evaluation is important before mass production - because it offers better experiences for applications and also prevent error.
