The housing 110 is typically formed from metal. The side wall of the housing 110 is provided with a plurality of connectors 111, and the connectors 111 facilitate electrical connection between the high-voltage control box 100 and other devices of the electrical apparatus.

Specifically, in the present embodiment, the plug connector 111 includes a plurality of charging plug connectors and a plurality of discharging plug connectors. The charging plug connector is used for being plugged with a charging port of the power utilization device, and the discharging plug connector is used for being plugged with a battery. When the battery is charged, the high-voltage control box 100 can control the connection between the charging plug connector and the discharging plug connector, so that the battery can be charged through the charging port. Because the charging connector is provided with a plurality of, so the charging port is correspondingly provided with a plurality of charging ports, thereby realizing double-gun charging.

Referring to fig. 2, an electrical component 120 is accommodated in the housing 110, and the electrical component has terminals 121. In this embodiment, the electrical component 120 is a relay, and the terminal 121 includes a first terminal and a second terminal. The first terminal and the second terminal are electrically connected to the charging plug and the discharging plug, respectively.

Referring to fig. 3 and 4, the wiring assembly 130 includes a connection row 131 and a plurality of terminals 132, and the connection row 131 and the terminals 132 can be formed of copper, aluminum, and other metals, and have good electrical conductivity. One end of the connection row 131 is mounted on the electric element 120 and electrically connected to the terminal 121, and a plurality of posts 132 are sequentially arranged on the connection row 131 and electrically connected to the connection row 131.

That is, the terminals 121 of the electric element 120 are electrically connected to the plurality of posts 132 through the connection rows 131, so each of the posts 132 corresponds to one of the terminals 12. Further, the terminals 132 are electrically connected to the corresponding connectors 111 through copper bars 140. In this way, the plurality of connectors 111 can be electrically connected to the same terminal 121 through the wiring assembly 130. Specifically, the plurality of charging connectors are electrically connected to the first terminal through the wiring assembly 130, and the plurality of discharging connectors 111 are electrically connected to the second terminal through the wiring assembly 130.

It is to be noted that, when the plurality of connectors 111 are electrically connected to the same terminal 121, the plurality of connectors 111 may be electrically connected to the plurality of posts 132 in sequence by the copper bars 140. Thus, only one copper bar 140 needs to be connected to each of the binding posts 132, and the plurality of copper bars 140 are separated from each other. Even if the copper bars 140 are loosened with the lapse of operation time, the sparking phenomenon is not easy to occur between the adjacent copper bars 140.

In this embodiment, the connection row 131 includes a first connection portion (not shown) extending along a first direction and a second connection portion (not shown) extending along a second direction perpendicular to the first direction. One end of the first connecting portion is fixed to the terminal 121, and the middle portion of the second connecting portion is fixedly connected with one end of the first connecting portion, which is far away from the terminal 121. It can be seen that the connecting row 131 is generally T-shaped.

In addition, in the present embodiment, the wiring assembly 130 includes an insulating support bracket 134, the connection row 131 is carried by the support bracket 134, and the support bracket 134 is fixed to the electrical component 120.

The support bracket 134 may be formed of a material having high mechanical strength, which is insulated by plastic, resin, etc., and mainly plays a supporting role for the connection row 131. The support brackets 134 are shaped similarly to the shape of the connecting rows 131, and are particularly generally T-shaped. The deformation of the connection row 131 can be effectively prevented by the supporting action of the supporting bracket 134, thereby improving the reliability of the high voltage control box 100.

Referring to fig. 5 and 6, a clearance hole 1345 is provided in the support bracket 134 at a position corresponding to the mounting hole 1311.

Specifically, the bottom of the post 132 may be integrally formed with the support bracket 134 by injection molding, so that the bottom of the post 132 is buried in the support bracket 134, thereby increasing the strength of the connection between the post 132 and the support bracket 134. The connection row 131 is provided with a plurality of through holes (not shown) arranged in sequence, and each of the binding posts 132 is formed with an external thread. When the wiring assembly 130 is assembled, the plurality of binding posts 132 on the support bracket 134 are respectively inserted into the plurality of through holes on the connecting row 131, and then the second locking nut 135 is mounted on the end of each binding post 132 and is screwed.

It should be noted that the post 132 needs to be held in contact with the inner wall of the through hole when passing through the through hole, so as to ensure that the post 132 can be electrically connected to the connection row 131.

In the present embodiment, the edge of the support bracket 134 is formed with a flange 1341 that is bent toward the connection bar 131, and a notch (not shown) is formed in a position of the flange 1341 corresponding to the copper bar 140 for the copper bar 140 to pass through.

The flange 1341 may increase the structural strength of the support bracket 134, thereby improving the supporting effect of the support bracket 134 on the connection row 131. Moreover, the notch can facilitate the installation of the copper bar 140, and prevent the copper bar 140 from interfering with the flange 1341.

In this embodiment, a limiting block 1342 is disposed on the surface of the support bracket 134, the limiting block 1342 encloses a limiting space, and the connection bar 131 is clamped in the limiting space.

In the present embodiment, a fixing hole 1343 is disposed on a side of the support bracket 134 facing away from the connection row 131, and a fixing bolt 136 is inserted through the fixing hole 1343 and screwed with the electrical component 120 to fix the support bracket 134 to the electrical component 120.

Specifically, the lower side of the electric component 120 is provided with a screw hole 123 (see fig. 2), and a fixing bolt 136 can pass through the fixing hole 1343 and be screwed with the screw hole 123, thereby fixing the support bracket 134 to the electric component 120. In this way, the mounting stability of the support bracket 134 is higher.

In addition, the reinforcing ribs 1344 are further arranged below the support brackets 134, and the reinforcing ribs 1344 can strengthen the support brackets 134, so that the support effect of the support brackets 134 on the connecting bars 131 is further improved.

In the high-voltage control box 100 and the power consumption device, the terminals 121 of the electric element 120 are electrically connected to the plurality of terminals 132 through the connection rows 131, so that each terminal 132 can function as a terminal 121. When electrically connecting the plurality of connectors 111 to the terminals 121 of the electrical component 120, the plurality of posts 132 may be electrically connected to the corresponding connectors 111 in sequence by the copper bars 140. It can be seen that only one copper bar 140 needs to be connected to each of the binding posts 132, and the plurality of copper bars 140 are disposed apart from each other. Even if the copper bars 140 are loosened with the lapse of operation time, the sparking phenomenon is not easy to occur between the adjacent copper bars 140.
