Converter and vehicle

The converter comprises a box body and a circuit board, the box body is provided with a bottom wall and a rib plate, and the rib plate is connected to the bottom wall and extends in the direction away from the bottom wall; the circuit board abuts against and is fixed to the rib plate, and the abutting area of the circuit board and the rib plate is suitable for being staggered from the position of a component installed on the circuit board. According to the converter provided by the embodiment of the utility model, the circuit board can be directly mounted on the rib plate of the box body, so that the assembly convenience and the assembly efficiency of mounting the circuit board on the box body are improved, the accumulated tolerance of the circuit board caused by secondary positioning can be reduced, and the difficulty of production process and mold design requirements is reduced; the assembling convenience and the assembling efficiency are improved, the box body structure is simplified, and the integration degree of the converter is improved; moreover, the interference between the abutting area and the component can be avoided, thereby improving the installation convenience and assembly efficiency of the component.
