The vehicle's electronic control system is provided with a conductive busbar, which has a three-phase connection position and a threaded hole on each of the three-phase connection positions. The edge of the vertical part 3 is overlapped on the conductive busbar, and the three second mounting holes 9 are aligned with the three threaded holes on the conductive busbar. Then, the bolt is screwed into the second nut 22, so that the bolt passes through the threaded hole of the conductive busbar and the second mounting hole 9. Then, a nut is tightened at the bottom of the bolt. Finally, the connecting arm 12 is bolted to the motor housing 1 for fixation.

[0044] According to the present invention, the motor terminal block has three connecting bars 14 installed in three independently configured mounting cavities 11, compared with the prior art. The heat generated by the three connecting bars 14 is isolated from each other, and the heat generated by the connecting bars 14 is directly transferred to the housing 1, which is conducive to heat dissipation of the motor terminal block, reduces the temperature rise of the motor terminal block, and improves the service life of the motor terminal block.
