[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides an outdoor switch power box, including a base 1, a box body 2 arranged on the base 1, a rainproof top cover 3 arranged on the box body 2, and a lap bar 4 above the knife switch, a knife switch 5, a lap bar 6 below the knife switch, a bus bar 7, a fuse 8, a surge protector 9, an insulating plate 10 and a ground bar 11, etc. arranged in the box body 2.

[0028] like Figure 1 、 Figure 3 and Figure 4 As shown, the base 1 is provided with multiple bolt holes 103, which are connected to the housing 2 via bolts. A first wire hole 101 and a second wire hole 102 are respectively provided on the front and rear sides of the base 1 to facilitate wiring. A third wire hole 104 is provided at the junction of the base 1 and the housing 2, which cooperates with the first and second wire holes 101, 102 to enable wire entry and exit from the bottom of the housing 2.

[0029] The housing 2 is provided with multiple connectors, such as a first connector 201 for connecting to the upper strapping bar 4 of the knife switch, a second connector 202 for connecting to the lower strapping bar 6 of the knife switch, and a third connector 203 for connecting to the busbar 7. These connections can be achieved through bolts. To improve insulation, insulating components such as insulating plates 10 can be installed between the connectors and the inner wall of the housing 2. The insulating plates 10, the connectors, and the housing 2 can be connected using bolts or other means.

[0030] like Figure 2 As shown, the rainproof roof 3 includes a bottom plate 301 connected to the box body 2 by welding or bolting, and a first inclined plate 302 and a second inclined plate 303 connected to the bottom plate 301 by welding or bolting. The arrangement of the first inclined plate 302 and the second inclined plate 303 improves the rainproof effect, prevents rainwater from entering the box body 2 or staying on the upper part of the box body 2, and ensures a dry environment inside the box body 2.

[0031] The two ends of the overlapping row 6 below the knife switch are respectively connected to the knife switch 5 and the overlapping row 7 below the knife switch; specifically, the knife switch 5 can be implemented by an existing knife switch, which mainly plays a segmented isolation role. For operational safety, an insulating protective plate is added to the outside of the knife switch as a whole.

[0032] like Figure 2 As shown, optionally, the bonding busbar 6 below the knife switch includes a first bonding busbar 601, a second bonding busbar 602, a third bonding busbar 603, and a fourth bonding busbar 604 arranged side by side in the left-right direction of the cabinet 2. The busbar 7 includes a first busbar 701, a second busbar 702, a third busbar 703, and a fourth busbar 704 arranged side by side in the front-to-back direction of the cabinet 2. The first bonding busbar 601, the second busbar 602, the third busbar 703, and the fourth busbar 603 are respectively connected to the first busbar 701, the second busbar 702, the third busbar 703, and the fourth busbar 704. While reducing the space occupied by multiple busbars in the cabinet, the outlet space of the outlet terminals is increased, ensuring wiring space and facilitating wiring.

[0033] In some embodiments, the first busbar 701, the second busbar 702, the third busbar 703 and the fourth busbar 704 are all provided with an output terminal 705; the first strap busbar 601, the second strap busbar 602, the third strap busbar 603 and the fourth strap busbar 604, and the connection points of the first busbar 701, the second busbar 702, the third busbar 703 and the fourth busbar 704 are arranged side by side along the left and right directions of the box body 2, and the wiring space of the output terminal 705 is guaranteed by the staggered connection method of the strap busbars and the busbars.

[0034] In some embodiments, the overlapping row 4 above the knife switch adopts a conventional overlapping row; in some other embodiments, optionally, the overlapping row 4 above the knife switch is designed as a flip-up row, extending the row at the upper mouth of the switch to the middle of the box body 2; because the outdoor box generally has the line in and out from the bottom, the row is flipped to the middle of the rear cabinet, which is more convenient for users to connect wires.

[0035] In some embodiments, the cabinet 2 optionally further includes a fuse 8 and a surge protector 9. The wiring of the fuse 8 and surge protector 9 is conventional and will not be described in detail here. The fuse 8 and surge protector 9 are fixed to the side of the cabinet by bolts or welding, arranged in an upper and lower arrangement, facilitating wiring. The vertical arrangement of the ground bar reduces the length of the direct connection from the surge to the ground bar, thereby increasing the wiring space for the ground bar.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
