Description

Technical Field

[0001] This invention relates to the field of electrical fault detection devices, and in particular to an electrical fault detection device for an automotive body controller. Background Technology

[0002] With the rapid evolution of automotive intelligence and connectivity technologies, vehicle electronic systems have become the core carrier for ensuring safe driving and improving ride comfort. The vehicle controller, as the "central nervous system" of the vehicle electronic system, bears the heavy responsibility of coordinating and managing key functions such as lighting control, window and door adjustment, wiper operation, anti-theft alarm, air conditioning control, and power distribution. The stability of its operation directly determines the normal operation of various vehicle electronic functions. Once an electrical fault occurs in the vehicle controller, it can not only lead to comfort function failures such as turn signal malfunction, wiper jamming, and fog light abnormalities, but also potentially cause safety hazards such as brake light failure and anti-theft system malfunction, seriously threatening the safety of passengers and road traffic. Therefore, an electrical fault detection device is needed to facilitate the detection and handling of vehicle body controllers.

[0003] Currently, traditional testing methods mainly rely on manual inspection and testing with specialized diagnostic equipment. Manual inspection depends on the experience and judgment of repair personnel, locating faults by visually inspecting the circuit and manually measuring voltage. This is not only inefficient and time-consuming, but also difficult to accurately identify hidden and related faults. In addition, the body controller models installed in different vehicle models are significantly different, and the corresponding connector specifications and pin definitions are different. In practical applications, specialized diagnostic equipment requires frequent replacement of matching wiring harnesses and connectors according to specific vehicle models. This is not only cumbersome and lacks universality, but also further prolongs the fault diagnosis cycle, causing many inconveniences for on-site testing and repair work. Summary of the Invention

[0004] This invention relates to an electrical fault detection device for automotive body controllers, which has an external connection part and a detection part. By configuring multiple flip-top connectors and corresponding detection wiring on an integrated board, the detection wiring can be flexibly replaced according to the connector specifications and pin definitions of different vehicle body controllers, without the need to equip a dedicated detection device for a single vehicle model. At the same time, the rotating connection structure between the flip-top connectors and the energized guide rod, combined with the storage function of the flip-top slot, not only ensures the orderly layout of multiple connectors, but also avoids the messy tangling of idle connectors, greatly improving the device's adaptability to different models of vehicle body controllers.
