Since the integrated interface 22 and the circuit board body 21 are already assembled as a whole, the assembly of the circuit board assembly 2 is completed at the same time as the integrated interface 22 is assembled with the heat dissipation housing 1.

It should be noted that, the integrated interface 22 and the heat dissipation housing 1 are cooperatively connected with the connection slot 12 through the connection block 2221, so two gaps are formed between the integrated interface 22 and the heat dissipation housing 1, and in order to fix the integrated interface 22 more firmly and increase the sealing performance of the controller, glue dispensing can be performed in the two gaps.

Optionally, a limiting groove 112 for positioning the circuit board body 21 is further disposed in the mounting through slot 11, when the circuit board body 21 is assembled, two side edges of the circuit board body 21 can be inserted into the limiting groove 112, and the circuit board body 21 is positioned by using the limiting groove 112, because the integrated interface 22 and the circuit board body 21 are fixed as a whole, the connection strength between the integrated interface 22 and the heat dissipation housing 1 can be further increased.
