Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] Reference Figures 1 to 12 An embodiment of the present invention provides a bus duct connection device, including a bus frame 200, a protective structure, two fixing brackets 300 and at least one first conductor 100.

[0038] The first conductors 100 are arranged in parallel, one end of each first conductor 100 is bent outward to form a wide end 110 , and the other end of each first conductor 100 forms a narrow end 120 .

[0039] Reference Figure 4 Specifically, in the illustrated embodiment, there are four first conductors 100. The wide ends 110 of two first conductors 100 are bent to the left and overlap, while the wide ends 110 of the other two conductors are bent to the right and overlap. Insulating material 600 is filled between adjacent conductors to prevent short circuits. For ease of description, the following embodiments will also use four as an example unless otherwise specified. However, those skilled in the art will appreciate that the number is not limited to that shown in the drawings or in the specific embodiments.

[0040] The busbar frame 200 is used to fix the first conductors 100. Each first conductor 100 is inserted into the busbar frame 200 and the wide end 110 passes through the busbar frame 200. The busbar frame 200 is provided with slots 210 equal in number to the number of first conductors 100. Figure 11shown.

[0041] The protection structure is used to cover a portion of the first conductor 100 .

[0042] Two fixing brackets 300 are fixedly connected to both sides of the busbar frame 200. The fixing brackets 300 are used to be fixedly connected to the switchgear so that the wide end 110 of the first conductor 100 extends out of the switchgear and docks with the standard busbar duct, and the narrow end 120 docks with the conductor in the switchgear.

[0043] The bus duct connection device of this embodiment is used to connect the standard bus duct and the switchgear on both sides. One end of each first conductor 100 arranged in parallel is bent outward to form a wide end 110, and the other end forms a narrow end 120. The first conductor 100 is inserted and fixed on the bus frame 200, and the wide end 110 passes through the bus frame 200. Fixed brackets 300 are provided on both sides of the bus frame 200. The fixed brackets 300 are fixed in the switchgear and fixedly connected to the top of the switchgear through the fixed brackets 300. The wide end 110 extends out of the switchgear and connects with the standard bus duct, while the narrow end 120 connects with the conductor in the switchgear. In this way, the standard bus duct and the switchgear are connected, the on-site connection form is solidified into a standard style, the starting box at the traditional connection point is eliminated, the tedious step of on-site measurement of the overlapping conductors is removed, and the efficiency of on-site bus duct connection is improved.

[0044] In addition, the first conductor 100 is effectively protected by the protective structure covering the portion of the first conductor 100 .

[0045] In some embodiments, the fixing bracket 300 includes a first connecting portion 310 and a second connecting portion 320. The first connecting portion 310 and the second connecting portion 320 are perpendicular to each other. The first connecting portion 310 is fixedly connected to a side surface of the busbar frame 200. A mounting hole is provided on the switchgear, and the first connecting portion 310 and the busbar frame 200 are engaged with the mounting hole. The second connecting portion 320 is provided with at least one first through-hole 321 for passing a fastener through to securely connect to the switchgear. A fastener, such as a bolt, is passed through the first through-hole 321 on the second connecting portion 320 and the switchgear and tightened to secure the entire busbar trunking connection device.

[0046] In some embodiments of the present invention, the main body 130 of the first conductor 100 is located between the wide end 110 and the narrow end 120. The protective structure includes a shield 400 and a covering structure 500. The shield 400 covers the wide end 110 of the first conductor 100, and the covering structure 500 covers the main body 130 of the first conductor 100. The shield 400 protects the portion of the wide end 110 of the first conductor 100 that extends beyond the busbar frame 200, while the covering structure 500 protects the main body 130 of the first conductor 100. The shield 400 and covering structure 500 effectively protect against dust and water. The uncovered narrow end 120 is connected to the conductor within the switchgear, while the end of the uncovered wide end 110 is connected to a standard bus duct.

[0047] Among them, at least one side surface, specifically two side surfaces, of the shield 400 are provided with a protruding edge 410 protruding outward, which is fixedly connected to the fixing bracket 300 through the protruding edge 410. Specifically, fasteners such as bolts can be used to pass through the protruding edge 410 and the second connecting part 320 of the fixing bracket 300 and lock and fix them.

[0048] Reference Figure 5 and Figure 6 One end of the covering structure 500 is fixedly connected to the shield 400. The covering structure 500 includes two cover plates 510 and two side plates 520. The two cover plates 510 are arranged opposite to each other, and the two side plates 520 are arranged opposite to each other. The two cover plates 510 and the two side plates 520 together form a cavity 550 for accommodating the main part 130 of the first conductor 100.

[0049] Reference Figures 5 to 7 In some embodiments, the side panel 520 includes a middle portion 521 and two third connecting portions 522 arranged on both sides of the middle portion 521. The third connecting portions 522 are fixedly connected to the cover plate 510. The middle portion 521 is protruding and has steps 523 formed at both ends. The steps 523 abut against one end of the cover plate 510 close to the cavity 550 for positioning, thereby realizing rapid positioning and installation of the cover plate 510 and the side panel 520.

[0050] In a further embodiment, the interior of the protruding middle portion 521 is provided with a plurality of hollow holes 524 running through it along the length direction, and the end face of the middle portion 521 close to the cavity 550 is a planar structure, which is convenient for filling the insulating material 600 between the middle portion 521 and the first conductor 100; the end of the middle portion 521 away from the cavity 550 is provided with a plurality of fins 525 arranged at intervals.

[0051] The current or voltage flowing through the bus duct is generally large, and the conductor connection is particularly prone to heat. By filling the space between one end plane of the middle portion 521 and the first conductor 100 with insulating material 600, and providing a hole 524 inside, and fins 525 at the other end, the heat dissipation capacity of the side plate 520 can be greatly increased, which is beneficial to the heat dissipation of the docking device.

[0052] Reference Figure 5 、 Figure 6 and Figure 8 In some embodiments of the present invention, the covering structure 500 further includes two sealing plates 530, the middle portion of the cover plate 510 is recessed to form a concave cavity 511, and protruding fourth connecting portions 512 are formed on both sides of the concave cavity 511. The two sides of the sealing plate 530 are bent inward to form bent portions 531, and the two bent portions 531 are cooperatively connected with the fourth connecting portions 512 on both sides of the cover plate 510.

[0053] The provision of the concave cavity 511 allows the fourth connecting portions 512 on either side of the cover plate 510 to deform to a certain extent, thus possessing a certain degree of elastic deformation. This improves the tightness of the connection between the outer end of the fourth connecting portion 512 and the bent portion 531 of the sealing plate 530, allowing the cover plate 510 to be connected to the sealing plate 530 by the force exerted by the cover plate 510. Furthermore, the thin-walled structure formed on both sides of the concave cavity 511 facilitates connection with the third connecting portion 522 of the side plate 520 via rivets 700. The concave cavity 511 provides space for connecting the side plate 520 and the cover plate 510 using rivets 700, facilitating the installation of both.

[0054] Reference Figure 6 In some embodiments, in the cavity 550, a first sealing strip 810 is embedded between the cover plate 510 and the sealing plate 530, a corner portion 513 is formed between the fourth connecting portion 512 on the cover plate 510 and the side wall of the concave cavity 511, and a second sealing strip 820 is embedded between the corner portion 513 and the third connecting portion 522 of the side plate 520.

[0055] Unlike one-piece molding, there are inevitable gaps in the connections between the panels. The sealing effect of the first sealing strip 810 prevents dust, water, etc. from entering the cavity 550 through the gap between the cover plate 510 and the sealing plate 530; and the second sealing strip 820 prevents dust, water, etc. from entering the cavity 550 through the gap between the cover plate 510 and the side plate 520.

[0056] In addition, a third sealing strip 830 is provided between the end of the cover plate 510 near the cavity 550 and the first conductor 100. The third sealing strip 830 fills the gap between the first conductor 100 and the cover plate 510, further improving the sealing performance. Filling the gap also makes the relative position of the first conductor 100 and the covering structure 500 more stable.

[0057] Specifically, the first sealing strip 810 , the second sealing strip 820 and the third sealing strip 830 are all made of silicone material.

[0058] Reference Figures 1 to 3 and Figure 10In some embodiments of the present invention, the covering structure 500 further includes two end plates 540. One end of the covering structure 500 is fixedly connected to the shield 400, and the other end of the covering structure 500 is sealed by the end plates 540. The inner sides of the two end plates 540 are provided with notches for the first conductor 100 to pass through. The outer sides of the end plates 540 are provided with vertical plates 541 that partially cover the narrow end 120 of the first conductor 100. The vertical plates 541 are perpendicular to the end plates 540. The vertical plates 541 partially cover the narrow end 120 of the first conductor 100, providing a certain degree of protection and support for the narrow end 120.

[0059] Reference Figures 5 to 7 , mounting posts 526 are provided on both sides of the middle portion 521 of the side panel 520, and the mounting posts 526 extend along the length direction of the middle portion 521. A second through hole 5261 is provided in the mounting posts 526, and the second through hole 5261 can be a threaded hole, one end of which is fixed by a fastener such as a bolt passing through the top of the shield 400 and inserted into the second through hole 5261, so as to relatively fix the shield 400 and the covering structure 500; the other end is fixed by a fastener such as a bolt passing through the end plate 540 and inserted into the second through hole 5261, so as to relatively fix the end plate 540 and the side panel 520.
