Description

Technical Field

[0001] The utility model relates to the technical field of power transmission, in particular to an electric busbar assembly and a power distribution cabinet including the same. Background Art

[0002] The power distribution cabinet plays a core role in power distribution. It can effectively transmit the electric energy of the power grid to various power consumption terminals to meet different power consumption needs. In addition, the power distribution cabinet also serves as a collection and distribution center of the power supply, reasonably distributing the input power signal to the devices that need electricity, so as to achieve efficient energy distribution.

[0003] Since the power distribution cabinet can be directly connected to the power grid, in order to improve the power transmission efficiency, the existing power distribution cabinets generally use copper busbars for wiring. In the prior art, first, a plurality of mounting holes need to be drilled on the copper busbar, and then the wiring terminal is connected to the copper busbar through the cooperation of a stud and a nut to realize the electrical connection between the electrical equipment and the power grid.

[0004] The prior art destroys the structure of the copper busbar itself. Although the stud can fill the vacancy of the connection hole to a certain extent, due to the differences in material and electrical parameters between the stud and the copper busbar, through laboratory tests, the non-destructive copper busbar has greater advantages in power transmission than the copper busbar with studs. Therefore, it is urgent to improve the prior art to improve the power transmission efficiency of the copper busbar. Summary of the Utility Model

The elastic pressing mechanism presses the wiring terminal under the action of the elastic force.

[0015] According to some embodiments of the present utility model, the number of the insulating seats is two. Each insulating seat includes a lower seat and an upper seat, and the lower seat and the upper seat are connected together to form a card slot capable of accommodating the busbar body.

[0033] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0034] As Figures 1 to 4 shown, the electric row assembly according to the first aspect embodiment of the present utility model includes an insulating seat 100, an electric row body 200, and a conductive ring 300. Among them, the insulating seat 100 is an insulating material member, and the number of it is two. The two insulating seats 100 are spaced apart at a certain distance. Each insulating seat 100 includes a lower seat 110 and an upper seat 120. The lower seat 110 is provided with two screw rods 130, and the upper seat 120 is provided with two through holes matching the screw rods 130. The through holes of the upper seat 120 are sleeved downward on the screw rods 130 of the lower seat 110, and the connection between the upper seat 120 and the lower seat 110 is realized by the threaded connection of the nuts and the screw rods 130. Both the lower seat 110 and the upper seat 120 are provided with a plurality of corresponding slots. When the lower seat 110 and the upper seat 120 are connected together, all the slots of the lower seat 110 and all the slots of the upper seat 120 jointly form a plurality of card slots 140 capable of accommodating the electric row body 200, and all the card slots 140 are arranged in the up and down direction.

[0035] When the busbar body 200 needs to be connected to two insulating bases 100, first remove the upper seats 120 of the two insulating bases 100, then place the two ends of the busbar body 200 in the slots of the two lower seats 110 respectively, and finally reconnect the upper seats 120 to the lower seats 110, so that the two ends of the busbar body 200 are clamped in the two card slots 140, thereby realizing the fixed connection of the busbar body 200. Since the two ends of the busbar body 200 are respectively connected to the two insulating bases 100 in a one-to-one correspondence, the busbar body 200 can realize wiring outside the two insulating bases 100 to provide more wiring space.

[0036] It can be understood that the present utility model does not limit the number of insulating bases 100. In other embodiments, the number of insulating bases 100 can also be one, three, etc., and is not limited to the above embodiments.

[0037] Generally speaking, there are three input ends 700 of the power distribution cabinet. Correspondingly, three busbar bodies 200 need to be provided, and the three busbar bodies 200 are respectively electrically connected to the three input ends 700. For this reason, each insulating base 100 is provided with at least three card slots 140. In this embodiment, the number of card slots 140 of each insulating base 100 is five, and the number is more than the number of busbar bodies 200. One end of the three busbar bodies 200 can be installed in any three card slots 140 of the insulating base 100 to adjust the distance between adjacent two busbar bodies 200, so as to cope with different working conditions. The higher the input current of the power grid, the greater the distance between adjacent two busbar bodies 200 needs to be. Therefore, the busbar assembly can be flexibly assembled according to different power requirements through the above settings.

[0038] In order not to damage the overall structure of the busbar body 200, each busbar body 200 is sleeved with a plurality of conductive rings 300. Each conductive ring 300 is of an annular structure, and its inner contour is adapted to the outer contour of the busbar body 200, and the inner dimension of the conductive ring 300 is not greater than the outer dimension of the busbar body 200, so that an interference fit is formed between the conductive ring 300 and the busbar body 200, thereby realizing the complete contact between the inner side surface of the conductive ring 300 and the outer side surface of the busbar body 200 to ensure the conductivity between the two. Each conductive ring 300 is provided with a wiring post 310 extending outward. The wiring post 310 is used for wiring with the input end 700 or the output end 800 of the power distribution cabinet to replace the stud in the prior art. Since the busbar body 200 and the conductive ring 300 are separately arranged, in order to improve the conductivity, it is best for the two to adopt the same conductive material, such as red copper, to avoid affecting the conductive effect due to different material properties of the busbar body 200 and the conductive ring 300.

[0039] Such as Figure 2 and Figure 4As shown, part of the terminal 310 has an external thread, and the terminal 310 is threadedly connected with a wire nut 400. When wiring is required, the terminal with the collar is first inserted into the terminal 310, and then the wire nut 400 is tightened to limit the relative position of the terminal on the terminal 310 to avoid the risk of disconnection. When the wiring needs to be removed, the wire nut 400 is first loosened and removed from the terminal 310, and then the terminal with the collar is removed from the terminal 310.

[0040] In addition, a groove 311 is provided on the outer side of another part of the terminal 310. At this time, the terminal 310 is in the shape of an "I" character. The terminal 310 is provided with an elastic pressing mechanism 500 at one end away from the conductive ring 300. The elastic pressing mechanism 500 has an elastic force tendency toward the conductive ring 300. Specifically, the elastic pressing mechanism 500 includes a spring 510 and a pressing sheet 520. The pressing sheet 520 is connected to the end of the terminal 310 away from the conductive ring 300 through the spring 510. At this time, the spring 510 provides the pressing sheet 520 with an elastic force tendency toward the conductive ring 300. When wiring is required, first move the pressing piece 520 to the end away from the conductive ring 300, at which time the spring 510 is compressed and in an energy storage state, then insert the terminal with an opening into the groove 311, and finally remove the force on the pressing piece 520. The pressing piece 520 presses the terminal under the elastic force of the spring 510, thereby limiting the relative position of the terminal on the terminal post 310 to avoid the risk of disconnection. When disconnection is required, first move the pressing piece 520 to the end away from the conductive ring 300, at which time the spring 510 is compressed and in an energy storage state, then remove the terminal with an opening from the groove 311, and finally remove the force on the pressing piece 520.

[0041] Of course, in some other embodiments, all the terminal posts 310 may be wired using the wire nuts 400, or all the terminal posts 310 may be wired using the elastic clamping mechanism 500, or other wiring structures may be used, without being limited to the above embodiments.

[0042] With the above structure, the arrangement of the conductive ring 300 saves the operation of drilling holes on the power strip body 200. When wiring is required, a specified number of conductive rings 300 are sleeved on the outside of the power strip body 200 according to the requirements, and the terminal 310 on the conductive ring 300 is used to achieve wiring with the terminal. Compared with the prior art, the utility model does not need to destroy the overall structure of the power strip body 200, and the position of the conductive ring 300 on the power strip body 200 can be freely defined to adapt to any working conditions, and is also convenient for recycling, and has a very high application prospect.

[0043] like Figure 4As shown, in some embodiments of the present utility model, each conductive ring 300 is provided with a locking mechanism 320. The locking mechanism 320 includes a positioning hole and a positioning screw 321. The positioning hole is provided in the conductive ring 300 and communicates with the busbar body 200. The positioning screw 321 is threadedly connected to the positioning hole. After the positioning screw 321 is tightened, the positioning screw 321 tightly abuts against the busbar body 200, thereby generating a pressure on the busbar body 200. Under the action of the thread, the conductive ring 300 is fixedly connected to the busbar body 200, thereby defining the relative position between the conductive ring 300 and the busbar body 200. When the positioning screw 321 is loosened, the conductive ring 300 can slide along the length direction of the busbar body 200 to adjust the position of the conductive ring 300 or remove the conductive ring 300. After the relative position between the conductive ring 300 and the busbar body 200 is defined, the position of the wiring terminal connected to the conductive ring 300 is also locked accordingly to prevent the position offset of the wiring terminal.

[0044] It should be noted that before installing or removing the conductive ring 300, the upper seat 120 and the lower seat 110 must be separated first to take out the busbar body 200. Moreover, the present utility model does not limit the specific structure of the locking mechanism 320. The locking mechanism 320 may also include a first tooth provided on the busbar body 200, a card hole provided on the conductive ring 300 and communicating with the first tooth, and a second tooth elastically connected to the conductive ring 300. When the second tooth passes through the card hole and meshes with the first tooth, the relative position between the conductive ring 300 and the busbar body 200 is locked at this time. It can be understood that as long as the locking mechanism 320 can achieve the position locking of the conductive ring 300 and the busbar body 200, no matter what structure the locking mechanism 320 is, it belongs to the protection scope of the present utility model.

[0045] As Figure 1 and Figure 2 shown, in some embodiments of the present utility model, an insulating layer 600 is provided beside each conductive ring 300 on the busbar body 200. The insulating layer 600 can reduce the probability of short circuit between adjacent two busbar bodies 200 and effectively reduce the possibility of contact between the busbar body 200 and external objects, thereby improving the safety performance of the busbar assembly.

[0046] In addition, insulating layers 600 of different colors can be provided on different busbar bodies 200. For example, red insulating material, green insulating material and yellow insulating material are used to insulate and cover three busbar bodies 200 to facilitate the distinction of different busbar bodies 200 and reduce wiring errors.

[0047] As Figure 2As shown in the figure, the power distribution cabinet according to the second aspect embodiment of the present utility model includes the busbar assembly according to the first aspect embodiment of the present utility model above, and further includes an input end 700 and an output end 800. Since the input end 700 is used to directly connect to the live wire of the power grid, a copper bar is preferably selected for it, while the output end 800 is used to connect to various electrical components, so ordinary wires can be selected for it. Since the number of input ends 700 is the same as the number of busbar bodies 200, all the input ends 700 are respectively connected to one wiring terminal 310 of all the busbar bodies 200 in a one-to-one correspondence; while the number of output ends 800 can be increased or decreased according to requirements, so the remaining wiring terminals 310 of each busbar body 200 are respectively used to connect to different output ends 800 to ensure that the input ends 700 and the output ends 800 are connected to different wiring terminals 310.

[0048] Since the power distribution cabinet adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here.

[0049] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present utility model.
