[0068] It should be noted that the glue injection port 3 is opposite to the through hole 6 , so that the terminal assembly 5 can be inserted into the through hole 6 from the glue injection port 3 to extend out.

[0069] It is worth noting that by reducing the length of the terminal assembly 5 and the busbar assembly 4, the stray inductance 16 parameter can be reduced and the electromagnetic compatibility performance can be improved.

[0070] In this embodiment, the glue filling port 3 is arranged on the first side of the shell 1 away from the controller module 2, so that the second side of the shell 1 facing the controller module 2 is easy to design, so that the second side can alleviate the technical problem of the long length of the busbar and the terminal in the bus capacitor through design.
