Common faults and causes of automotive wiring harnesses are: poor contact of plug-in connectors, short circuits, open circuits, lap joints, etc. between wires. The main reasons for the failure of automobile wiring harness are the following aspects: natural factors The service life of the wiring harness is ultra-long, the wire is aging, the insulation layer is damaged, and the mechanical strength is not up to standard, resulting in short circuits, open circuits and towers between circuits, burning out the wiring harness.
Common specification name: 30AWG 28AWG 26AWG 24AWG 22AWG 20AWG 18AWG Rated temperature: 80°C-105°C Rated voltage: 300V-600V, standard: UL758, ULL581 and CSA NO. The conductor uses a single or stranded wire 32AWG–16AWG bare copper or tinned copper, PVC insulation, can pass UL VW-1 and CSA FT1 vertical flame resistance test, using standard thickness, easy to peel, easy to cut, with acid and alkali resistance, oil resistance, moisture resistance, mildew and other characteristics.
In modern cars, there are especially many automotive wiring harnesses, and the electronic control system is closely related to the wiring harness. Someone once made an image analogy: if the function of microcomputer, sensor and executive element is compared to the human body, it can be said that the microcomputer is equivalent to the human brain, the sensor is equivalent to the sensory organ, and the executive element is equivalent to the motor organ, then the wiring harness is a nerve and blood vessel.
Intelligent Manufacturing (IM) is a human-machine integrated intelligent system composed of intelligent machines and human experts, which can carry out intelligent activities in the manufacturing process, such as analysis, reasoning, judgment, conception and decision-making.
