Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0030] A combined bus bar includes a main housing 1, and a plurality of sub-housings 2 are sequentially installed on one side of the main housing 1. Three installation cavities 3 are respectively opened at the bottom of the main housing 1 and the bottom of the sub-housing 2, and a first conductive bus bar 301, a second conductive bus bar 302, and a third conductive bus bar 303 are respectively installed in the three installation cavities;

[0031] Inside the main housing 1, a first connecting busbar 4, a second connecting busbar 5, and a third connecting busbar 6 are installed. Inside the sub-housing 2, a first distribution busbar 7, a second distribution busbar 8, and a third distribution busbar 9 are installed. The first distribution busbar 7 and the first connecting busbar 4 are both fixedly installed with the first conductive busbar 301. The second connecting busbar 5 and the second distribution busbar 8 are both fixedly installed with the second conductive busbar 302. The third connecting busbar 6 and the third distribution busbar 9 are both fixedly installed with the third conductive busbar 303.

[0032] As Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9 , the first conductive busbar 301, the second conductive busbar 302, and the third conductive busbar 303 are arranged in parallel and do not contact each other. The cavities 3 at the bottoms of the main housing 1 and the sub-housing 2 are connected together to form a space for accommodating the first conductive busbar 301, the second conductive busbar 302, and the third conductive busbar 303. One ends of the first connecting busbar 4, the second connecting busbar 5, the third connecting busbar 6, the first distribution busbar 7, the second distribution busbar 8, and the third distribution busbar 9 all protrude outside the main housing 1 and the sub-housing 2.

[0033] A bent portion that bends downward is provided on the first connecting busbar 4. A fixing bolt 10 is provided above the bent portion. A fixing nut 11 is provided at the bottom of the first conductive busbar 301. The bottom of the fixing bolt 10 sequentially penetrates the first connecting busbar 4 and the first conductive busbar 301 and is threadedly connected to the fixing nut 11 to realize the fixed installation of the first connecting busbar 4 and the first conductive busbar 301.

[0034] As Figure 8 , Figure 9 and Figure 10 , by providing a bent portion on the first connecting busbar 4 and then fixedly connecting through the fixing bolt 10 and the fixing nut 11, when the first connecting busbar 4 and the first conductive busbar 301 are fixed together, they will not contact the second conductive busbar 302 and the third conductive busbar 303. Similarly, bent portions are provided on the second connecting busbar 5, the third connecting busbar 6, the first distribution busbar 7, the second distribution busbar 8, and the third distribution busbar 9, and they are fixed through bolts and nuts, so that the second connecting busbar 5, the third connecting busbar 6, the first distribution busbar 7, the second distribution busbar 8, and the third distribution busbar 9 will only be connected to the corresponding conductive busbars.

[0035] A main top cover 12 is provided at the top of the main housing 1, and a sub-top cover 13 is provided at the top of the sub-housing 2. Ventilation slots are provided on both the main top cover 12 and the sub-top cover 13.

[0036] As Figure 1 , the main top cover 12 and the sub-top cover 13 can enclose the main housing 1 and the sub-housing 2 from above, and the ventilation slots facilitate the ventilation and heat dissipation inside the main housing 1 and the sub-housing 2.

[0037] Spring pieces 15 are fixedly connected to the bottoms of the main top cover 12 and the sub-top cover 13, and a buckle 16 is fixedly connected to the bottom of the spring piece 15. The buckle 16 is inclined, and buckle grooves 17 for cooperating with the buckle 16 are formed on both the main housing 1 and the sub-housing 2.

[0038] As Figure 1 、 Figure 4 、 Figure 6 and Figure 7 , when the main top cover 12 is moved downward, the inclined surface of the buckle 16 under the main top cover 12 is disengaged from the main housing 1, and the main housing 1 presses the inclined surface of the buckle 16, causing the spring piece 15 to bend inward. Until the main top cover 12 is completely covered above the main housing 1, the spring piece 15 resets, and the buckle 16 is clamped into the buckle groove 17, clamping the main top cover 12 above the main housing 1. Similarly, the sub-top cover 13 and the sub-housing 2 are clamped together in the same way.

[0039] Insulating baffles 14 are bonded to the bottoms of the main housing 1 and the sub-housing 2, and the insulating baffles 14 are used to enclose the installation cavity 3.

[0040] As Figure 1 and Figure 2 , when installing the first conductive bus bar 301, the second conductive bus bar 302, and the third conductive bus bar 303 into the cavity 3, the insulating baffle 14 can be fixed to the bottoms of the main housing 1 and the sub-housing 2 through a curing adhesive.

[0041] A trapezoidal card slot 18 is formed on one side of the main housing 1, and a trapezoidal clamping member 19 for cooperating with the trapezoidal card slot 18 is fixedly connected to one side of the sub-housing 2.

[0042] As Figure 1 、 Figure 4 and Figure 5 , moving the sub-housing 2 downward from one side of the main housing 1 can make the trapezoidal clamping member 19 just snap into the trapezoidal card slot 18, clamping the main housing 1 and the sub-housing 2 together. The sub-housings 2 are also clamped together through the cooperation of the trapezoidal clamping member 19 and the trapezoidal card slot 18.

[0043] Compared with the related art, a combined bus bar provided by the present utility model has the following beneficial effects:

[0044] The utility model connects the main housing 1 and the sub-housing 2 together, and arranges three conductive busbars below the main housing 1 and the sub-housing 2. A connecting busbar and a plurality of distribution busbars are connected to each conductive busbar, so that the connecting busbar can be electrically connected to the plurality of distribution busbars, rather than connecting a single busbar, and more electrical equipment can be connected for power distribution.

[0045] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the description in the specification only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model.
