As shown in fig. 1-2, the power board box includes a box body 1, a metal plate 2 is disposed on a side surface of the box body 1, the metal plate 2 is disposed in parallel with a power board 3 disposed in the box body 1, and the metal plate 2 is disposed between the power board 3 and a connecting board/reinforcing board. The metal plate 2 and the power supply plate 3 located in the box body 1 may also be disposed in a non-parallel manner in other embodiments, and in this embodiment, the metal plate 2 is located on the outer side wall of the box body 1. That is, the power panel 3 and the metal plate 2 are separated by the box body 1, and the arrangement mode can prevent the metal plate 2 and the power panel 3 from contacting due to small gap and influencing the use of the power panel 3.
In the power board box provided in this embodiment, the metal board 2 is disposed thereon, and since the metal board is made of conductive metal, the dielectric constant of the metal board is relatively low compared to that of insulating materials such as air and water, and thus the capacitance of a flat capacitor formed by the power board 3 and the reinforcing plate/connecting plate made of metal can be reduced. The influence of the power panel on the power grid is effectively reduced.
The metal plate 2 can be fixed on the side surface of the box body 1 in an adhering or embedding way. Specifically, the side of the box body 1 may be provided with a groove 4 for accommodating the metal plate 2. The groove 4 is formed by a plurality of convex ribs, specifically, the number of the convex ribs is not less than four, and the four convex ribs are connected in sequence to form a rectangular groove 4. Of course in other embodiments the number of ribs is one, which is an annular rib. It should be noted that the depth of the groove 4 is greater than the thickness of the metal plate 2. The metal sheet 2 that this embodiment provided is sheet metal, and its thickness is less, can not cause the whole volume increase of power supply board box more.
As shown in fig. 1, the rib includes a connecting rib 5 and a holding rib 6, the holding ribs 6 are connected to form the groove 4, the number of the holding ribs 6 in the embodiment is four, and the connecting rib 5 is connected to the outer side wall of the holding rib 6 and used for reinforcing the groove 4, so that the groove 4 is prevented from being damaged by external force. Above-mentioned 1 lateral wall of box body has still extended reinforcing rib 7, and wherein reinforcing rib 7 quantity is the same with the quantity that holds muscle 6, and splice bar 5 is connected with holding muscle 6 and reinforcing rib 7 respectively, and then can effectively consolidate this recess 4.
In order to prevent the metal plate 2 from being separated from the groove 4, an elastic buckle (not shown in the figure) is further arranged on one side of the metal plate 2 contacting the accommodating rib 6, the elastic buckle and the accommodating rib 6 are of an integrated structure, and when the metal plate 2 is installed, the metal plate 2 can be installed and completed only by pressing the metal plate 2 to enable the elastic buckle to deform.

That is, there is no box 1 to separate the power board 3 from the metal board 2, and it should be noted that there is no contact between the metal board 2 and the power board 3 in this arrangement, so as to prevent the pins on the power board 3 from contacting the metal board 2 to affect the power grid where the power board 3 is located.
The metal plate 2 can be fixed on the side surface of the box body 1 in an adhering or embedding way. Specifically, the side of the box body 1 may be provided with a groove 4 for accommodating the metal plate 2. The groove 4 is formed by a plurality of convex ribs, specifically, the number of the convex ribs is not less than four, and the four convex ribs are connected in sequence to form a rectangular groove 4. It should be noted that the depth of the groove 4 is greater than the thickness of the metal plate 2. Wherein the ribs also play a role in supporting the power panel 3. Further, the power supply plate 3 and the metal plate 2 can be kept from contact with each other.
