Critical Product Advantages
Premium Engineering Material
Constructed from high-performance PA66, this
housing offers superior chemical resistance to automotive fluids (oil, fuel,
coolant) and maintains dimensional stability even under extreme thermal stress.
01
High Current Capability
Designed for 6.3mm terminal systems, it is
optimized for high-power circuits, supporting currents typically
exceeding 10A, making it far more robust than standard 1.5mm or 2.8mm
connectors.
02
Secure Locking System
Features an integrated primary locking mechanism.
Once the terminal is inserted, the internal barb structure ensures a secure
fit, preventing "terminal back-out" caused by road shock or engine
vibration.
03
Precision Fit & Ergonomics
Produced via high-precision molds to ensure a
low-insertion-force experience for assembly line workers while maintaining a
secure, audible-click connection.
04
Primary Application Scenarios
The versatility of the 3-way configuration makes it essential for various
vehicle subsystems:
Powertrain & Engine Bay
Connection for sensors, ignition coils, and cooling fan motors.
01
Exterior Lighting Systems
High-reliability interface for headlight assemblies, fog lamps, and auxiliary lighting.
02
Climate Control (HVAC)
Power supply for air conditioning blowers and condenser fan actuators.
03
Electric Mobility
Battery management systems (BMS) and signal distribution for E-bikes and motorcycles.
04
Custom Harness Assembly
A preferred choice for automotive aftermarket repairs and performance vehicle wire harness modifications.
05
