I. Structure and Composition
The motor wiring harness of an automotive blower is usually composed of the following parts:
Wire: Wrapped with high-temperature resistant and wear-resistant insulating materials to ensure stable current transmission.
Connectors: They are used to connect motors, power supplies, control modules, etc., and usually have waterproof and dustproof designs.
Protective sleeve: The outer layer is wrapped with protective material to prevent the wire harness from wearing out or short-circuiting.
Fixing devices: such as clips, cable ties, etc., are used to fix the wiring harness to prevent damage caused by vibration or friction.
Functions and Roles
Power transmission: Transfer the electrical energy from the vehicle's power supply to the blower motor to drive its operation.
Signal transmission: Transmits instructions from the control module to achieve functions such as wind speed regulation and switch control.
Protection function: Through components such as fuses and relays, it prevents damage to the motor or circuit caused by overload or short circuit.
