The component case 9 is a case of a component of a fuel cell hybrid vehicle. The component of the fuel cell hybrid vehicle may be a DC/DC converter or other components, and the component housing 9 may be a housing of the DC/DC converter or other components, which is not particularly limited and is within a protection range.
It is understood that the high voltage contactor module 1 may be mounted on an outer wall of the component housing 9 such that the power distribution unit and the components of the fuel cell hybrid vehicle are connected to each other and exposed to an outside of the components; and the power distribution unit can also be arranged on the inner wall of the part shell 9, so that the power distribution unit is integrated in the parts of the fuel cell hybrid electric vehicle, and the arrangement of the whole vehicle is further optimized.
In this embodiment, the other modules include a fuse module 4, a power module 6, a control module 7, and a connection module 8. The fuse module 4 is connected with the output circuit board 303; the power supply module 6 is used for distributing power to the high-voltage contactor module 1; the control module 7 is used for controlling the opening and the disconnection of the high-voltage contactor module 1; the connection module 8 is used for controlling the signal connection between the high-voltage contactor module 1 and the control module 7. Of course, other modules may include only any one or more of the fuse module 4, the power module 6, the control module 7, and the connection module 8, and may include other types of modules.
In order to facilitate the connection between the high voltage contactor module 1 and the integrated circuit module 3, the integrated circuit module 3 is provided with conductive holes, which include an input conductive hole 3041 and an output conductive hole 3042; the input conductive hole 3041 is connected to an input circuit of the input circuit board 301, and the output conductive hole 3042 is connected to an output circuit of the output circuit board 303; the input end of the high voltage contactor module 1 is connected to the input conductive hole 3041 through the conductive post 2, and the output end of the high voltage contactor module 1 is connected to the output conductive hole 3042 through the conductive post 2.

In this embodiment, the high voltage contactor module 1 may include a plurality of high voltage contactors, and the different heights of the types of the plurality of high voltage contactors may also be different, so that the placement angle of the integrated circuit module 3 may be adjusted by adjusting the length of the conductive column 2, for example, the integrated circuit module 3 is arranged in parallel with the component housing 9, so that the length direction of the conductive column 2 is perpendicular to the integrated circuit module 3, and the conductive connection stability is effectively improved.
In a power distribution unit having a large size in the height direction (the arrangement direction of the high-voltage contactor module 1 and the integrated circuit module 3), the high-voltage contactor module 1 and the integrated circuit module 3 may be connected without using the conductive column 2.

The conductive column 2 has an inner diameter and an outer diameter, wherein the inner diameter of the conductive column 2 is the diameter of the inner hole, and the outer diameter of the conductive column 2 is the diameter of the outer wall (cylindrical structure). Therefore, the mounting interface structure of the high-voltage contactor module 1 may be configured as a ring-shaped recessed structure, an outer ring diameter of the ring-shaped recessed structure is equal to an outer diameter of the conductive post 2 (a difference between the two is within an allowable machining error), and an inner ring diameter of the ring-shaped recessed structure is equal to an inner diameter of the conductive post 2 (a difference between the two is within an allowable machining error).
