Among them, the plurality of electrical components 120 include at least two of a relay 121, a busbar 122 (i.e., an AC busbar), and an air switch component 123. That is to say, at least two of the relay 121, the busbar 122, and the air switch component 123 are integrated on the circuit board 110.

[0058] Moreover, since at least two of the relay 121, the busbar 122, and the air switch component 123 are arranged on the circuit board 110, when assembling the distribution box, only the circuit board 110 needs to be installed and fixed to achieve the overall installation of the busbar device 100, avoiding the problem that due to the separate arrangement of a plurality of electrical components 120, it is necessary to design and assemble parts separately for each electrical component 120, resulting in an increase in mold cost and assembly cost, which is beneficial to improving the assembly efficiency of the distribution box and reducing the production cost of the distribution box.

Moreover, during assembly, only fixing the circuit board 110 can achieve the overall fixed installation of the busbar device 100, without the need to separately design assembly parts for the relay 121 and the air switch component 123, which is beneficial to reducing the mold cost and the assembly cost and improving the assembly efficiency.

[0061] At least a part of the relay 121 and at least a part of the air switch component 123 are respectively located on opposite sides of the circuit board 110. That is to say, the relay 121 and the air switch component 123 are distributed on opposite sides of the circuit board 110. While meeting the usage requirements, compared with arranging the relay 121 and the air switch component 123 on the same side of the circuit board 110, it is beneficial to reduce the overall size of the circuit board 110, further reduce the occupied space of the busbar device 100 in the distribution box, reduce the volume of the distribution box, and enhance the competitiveness of the product.

That is to say, the multiple relays 121 are arranged on one side of the circuit board 110, and the air switch component 123 is arranged on the other side of the circuit board 110.

Compared with the related art in which the relay, the AC bus bar, and the air switch in the distribution box are arranged separately, the plurality of electrical components 120 with different functions are converged onto the circuit board 110, with clear functional areas, avoiding unnecessary wiring and enhancing the aesthetics. In addition, the complex current is organically integrated, further improving the space utilization rate inside the distribution box and reducing the product volume.

[0067] Moreover, since the relay 121, the bus bar 122, and the air switch component 123 are all arranged on the circuit board 110, when assembling the distribution box, only the circuit board 110 needs to be installed and fixed to achieve the overall installation of the bus bar device 100, avoiding the problem that due to the separate arrangement of the plurality of electrical components 120, it is necessary to design and assemble parts separately for each electrical component 120, resulting in an increase in mold cost and assembly cost, further improving the assembly efficiency of the distribution box and reducing the production cost of the distribution box.

[0068] The bus bar 122 and the relay 121 are located on the same side of the circuit board 110, that is to say, the bus bar 122 and the relay 121 are located on one side of the circuit board 110, and the air switch component 123 is located on the other side of the circuit board 110. That is, the installation positions of the respective electrical components 120 integrated on the circuit board 110 are reasonably arranged, which is beneficial to reducing the size of the circuit board 110, saving area and space while meeting the use requirements.

[0069] It can be understood that the bus bar 122 is used to connect to the power supply.

[0070] As Figure 1 and Figure 2 shown, in some embodiments, optionally, the air switch component 123 includes a switch body 130 and a conductive connection member 140. Among them, the switch body 130 and the relay 121 are located on opposite sides of the circuit board 110, the conductive connection member 140 is provided on the circuit board 110, and the switch body 130 is electrically connected to the circuit board 110 through the conductive connection member 140.

Specifically, the switch body 130 and the relay 121 are respectively arranged on two opposite sides of the circuit board 110. The conductive connection component 140 is arranged on the circuit board 110, and the switch body 130 is electrically connected to the circuit board 110 through the conductive connection component 140.

[0072] Optionally, the conductive connection component 140 includes an air switch connection row.

Specifically, a via 111 is provided on the circuit board 110, and the connection portion 141 passes through the via 111 and is connected to the switch body 130. The limiting portion 142 is on the same side of the circuit board 110 as the relay 121. That is to say, the limiting portion 142 and the switch body 130 are on two opposite sides of the circuit board 110.

[0075] The limiting portion 142 abuts against the circuit board 110, so that while realizing the conductive connection between the switch body 130 and the circuit board 110, the reliable fixation of the switch body 130 on the circuit board 110 can also be realized.

[0076] Optionally, the connection portion 141 and the limiting portion 142 are of an integral structure.

[0079] In addition, it is also possible to avoid the problem that since multiple electrical components 120 are separately arranged, it is necessary to separately design and assemble parts for each electrical component 120, resulting in an increase in mold cost and assembly cost, further improving the assembly efficiency of the distribution box and reducing the production cost of the distribution box.

[0080] The bus bar 122 and the limiting portion 142 are respectively located on both sides of the relay 121. That is to say, the arrangement positions of the bus bar 122, the limiting portion 142 and the relay 121 on the same side of the circuit board 110 are reasonably arranged to save the area of the circuit board 110, reduce the overall size of the circuit board 110, which is beneficial to reducing the overall volume of the bus bar device 100, and further reducing the occupied space of the bus bar device 100 in the distribution box.
