Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a current distribution and shunt device for a distribution box. Background Technology

[0002] A distribution box is a device used to distribute electrical energy. It is usually installed inside buildings, such as homes, offices, or small commercial spaces. The main function of a distribution box is to distribute power to various rooms or electrical appliances.

[0003] A distribution box consists of switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment, all assembled in a closed or semi-closed metal cabinet. The distribution box can connect or disconnect circuits manually or automatically, and in the event of a fault or abnormal operation, it will cut off the circuit or trigger an alarm via protective electrical appliances.

[0004] Traditional distribution boxes typically contain multiple copper busbars. Due to the large number of electrical components, the number of electrical components that a single copper busbar can connect is limited. Therefore, the applicant has made a useful design and found a way to solve the above problem. The technical solution to be introduced below is based on this background. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the aforementioned background technology and to provide a product that controls temperature rise and increases electrical connection ports.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A current distribution box shunt and combiner device includes a box body, a first air switch, and a second air switch. The box body is provided with a mounting plate, the lower part of which has a plurality of air inlets, and the upper part of which has a plurality of heat dissipation holes. The air inlets and heat dissipation holes are in direct contact with the air outside the box body. The mounting plate is provided with a base, and the base is provided with at least a first copper busbar. The first copper busbar is electrically connected to the first air switch. The second air switch is disposed on both sides of the base and is electrically connected to the first copper busbar.

[0008] Preferably, a conductive sheet is provided between the two first copper busbars, an insulating plate is provided between the two conductive sheets, conductive parts are provided on both sides of the conductive sheet and protrude from both sides of the base, and the conductive parts are electrically connected to the wiring port of the second air switch.

[0009] Preferably, the base is provided with a partition and is disposed between two first copper busbars.

[0010] Preferably, the base is provided with a cover plate, and a through hole is provided between the cover plate and the base for the conductive component to pass through. The cover plate and the base are fixed by fastening screws, so that the base and the cover plate form a clamping force that clamps the first copper busbar and the conductive sheet. Several first ventilation holes are provided on both sides of the cover plate, and a vent plate is provided above the base and the cover plate. The vent plate is provided with several second ventilation holes.

[0011] Preferably, the circuit also includes a grounding group, which is disposed on both sides of the first air switch. A second copper busbar is provided between the common terminals of the two grounding groups. The grounding group includes two grounding terminal blocks arranged in a stepped manner. A third copper busbar is provided between the common terminals of the grounding terminal blocks.

[0012] Preferably, the first air switch is further provided with a fourth copper busbar and is electrically connected to the second copper busbar.

[0013] Beneficial effects:

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] (1) In this utility model, the first air switch provides electrical energy to the first copper busbar, and the first copper busbar conducts electrical energy to multiple second air switches, which solves the technical problem of too many electrical components and too few electrical connection ports, and makes the product have the advantage of increasing electrical connection ports.

[0016] (2) In this utility model, when a large current passes through the first copper busbar, the temperature of the first copper busbar rises rapidly. The hot air is heated and its density decreases, so it is discharged from the ventilation hole and rises. The hot air is discharged from the box through the heat dissipation hole, and the cold air enters the box through the air inlet hole to replenish the air in the box, thereby forming an air convection circulation. Through the above design, there is no need for a heat dissipation device, so natural heat dissipation is achieved, reducing the operating load of the first copper busbar and effectively controlling the temperature rise of electrical components and copper busbar.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Reference example Figures 1 to 3A current distribution box shunt and combiner device includes a box body 1, a mounting plate 4 inside the box body 1, at least one first air switch 2 and a second air switch 3 inside the mounting plate 4, a plurality of air inlets 41 below the mounting plate 4, and a plurality of heat dissipation holes 42 above the mounting plate 4. The air inlets 41 and heat dissipation holes 42 are in direct contact with the air outside the box body 1. The mounting plate 4 is provided with a base 5, and the base 5 is provided with at least one first copper busbar 6. The first copper busbar 6 is electrically connected to the first air switch 2. The second air switch 3 is provided on both sides of the base 5 and is electrically connected to the first copper busbar 6.

[0034] The first air switch 2 provides power to the first copper busbar 6, which then distributes the power to multiple second air switches 3, solving the technical problem of too many electrical components and too few electrical connection ports. When the first copper busbar 6 carries a large current, its temperature rises rapidly. The hot air, with its reduced density due to heat, is discharged and rises through the first ventilation hole 521 and the second ventilation hole 541. The hot air is discharged from the housing 1 through the heat dissipation hole 42, while cold air enters the housing 1 through the air inlet 41 to replenish the air inside the housing 1. The cold air enters the base 5 and the cover plate 52, thus forming an air convection circulation. Through the above design, no heat dissipation device is needed, achieving natural heat dissipation, reducing the operating load of the first copper busbar 6, and effectively controlling the temperature rise of electrical components and the copper busbar.

[0035] It is worth mentioning that a conductive sheet is provided between the two first copper busbars 6, and an insulating plate 62 is provided between the two conductive sheets. Conductive parts 611 are provided on both sides of the conductive sheet and protrude from both sides of the base 5.

The conductive sheets are stacked vertically, and the conductive parts 611 divert the electrical energy of the first copper busbars 6 to the second air switch 3.

[0036] It is worth mentioning that the base 5 is provided with a partition 51 and is disposed between the two first copper busbars 6. The partition 51 increases the creepage distance of the two first copper busbars 6.

[0037] It is worth mentioning that the base 5 is provided with a cover plate 52, and a through hole 53 for conductive components to pass through is provided between the cover plate 52 and the base 5. The cover plate 52 and the base 5 are fixed by fastening screws 8, so that the base 5 and the cover plate 52 form a clamping force that clamps the first copper busbar 6 and the conductive sheet. Several first ventilation holes 521 are provided on both sides of the cover plate 52. A vent plate 54 is provided above the base 5 and the cover plate 52. The vent plate 54 is provided with several second ventilation holes 541. The cover plate 52 plays the role of protecting the first copper busbar 6, the insulating plate 62, and the conductive sheet. The first copper busbar 6 and the conductive sheet are tightly connected by fastening screws 8 to reduce contact resistance. Hot air inside the cover plate 52 is discharged through the first ventilation holes 521 and the second ventilation holes 541.

[0038] It is worth mentioning that it also includes a grounding group 7, which is set on both sides of the first air switch 2. A second copper busbar 71 is provided between the common terminals of the two grounding groups 7. The grounding group 7 includes two grounding terminal blocks 72, which are arranged in a stepped manner. A third copper busbar 73 is provided between the common terminals of the grounding terminal blocks 72.
