In the context of increasingly complex modern automotive electronic systems, the On-Board Diagnostics (OBD) interface has become a core channel for vehicle health monitoring, fault diagnosis, performance tuning, and vehicle-to-everything (V2X) data acquis

As one of the commonly used standardized interfaces in automotive or industrial equipment, the 9-pin diagnostic connector must possess excellent electromagnetic interference resistance while undertaking fault diagnosis, parameter reading, and communicatio

Although low temperature itself does not induce thermal aging, the embrittlement of the material at low temperature will reduce its resistance to mechanical fatigue.

In modern automotive electronic systems, OBD cables serve as the "neural pathway" between diagnostic equipment and the vehicle's brain, carrying the mission of transmitting critical data.

In the electronic systems of heavy-duty vehicles, construction machinery, and commercial vehicles, the 9-pin diagnostic connector plays a crucial role—it serves as the bridge between the vehicle's brain and external diagnostic equipment, transmitting crit

In modern automotive electronic systems, the OBD connector is no longer just a simple physical interface; it serves as the "nerve center" for data communication between the vehicle and the outside world.
