The Harness Continuity Test System is a critical equipment used to test whether the wire connections in the harness (cable assembly) are correct, whether there are short circuits, open circuits, misalignment, and other issues. It is widely used in various industries, especially in fields that require high reliability electrical connections. The following are its main application industries and specific scenarios:
Automobile industry
Application scenarios:
Traditional automobiles: Check the connection reliability of wiring harnesses such as ECU (Electronic Control Unit), dashboard, headlights, sensors, etc.
New energy vehicles: Conduct conductivity and insulation resistance tests on high-voltage wiring harnesses (such as batteries, motors, charging interfaces) to ensure the safety of high-voltage systems (such as 800V platforms).
Production line inspection: Quickly screen for wire harness defects in the final assembly line to avoid rework of the entire vehicle.
Typical case: Tesla, BYD and other car companies use automated continuity testing in production, where a single device can cover hundreds of testing points.
Aerospace and Military Industry
Application scenarios:
Aircraft wiring harness: Check the conductivity and anti-interference ability of the avionics system and engine control wiring harness (in accordance with standards such as MIL-STD-704).
Satellite/Rocket: Reliability Verification of Wiring Harness in Extreme Environments (High Temperature, Vibration).
Military equipment: rapid fault location of complex wiring networks such as armored vehicles and radars.
Typical case: In the wiring harness testing of COMAC C919 aircraft, a military grade test bench supporting multiple channels (1000+points) was used.
