[0030] like Figure 1-3 As shown, the utility model provides a bus duct with adjustable length, comprising a bus duct outer plate body 1 and busbars 2 installed inside the bus duct outer plate body 1 .

[0031] The bus duct structure includes a straight connecting plate 3, a covering plate 4, a connecting assembly plate 5, an insulating busbar sleeve 6 and a supporting block 7.

[0032] Among them, one end of the straight connecting plate 3 can be fixedly connected to the end of the outer plate body 1 of the bus duct by bolts, and the straight connecting plate 3 is provided with a through hole for the connecting long axis 51 to cross. The covering plate 4 is a U-shaped structure, which is provided with a pair and is respectively located on the upper and lower sides of the busbar 2. A pad 41 for flatly contacting the busbar 2 to position the insulating busbar sleeve 6 is fixedly connected to the surface of the covering plate 4 facing the busbar 2. A positioning groove 411 is provided on one side of the surface of the pad 41 for the end of the insulating busbar sleeve 6 to be inserted. When the end of the insulating busbar sleeve 6 is inserted into the positioning groove 411, the through holes of the insulating busbar sleeve 6 and the busbar 2 can be aligned, which is convenient for the connecting long axis 51 to pass through at the same time.

[0033] There is a pair of connection assembly plates 5, one of which is provided with a through hole aligned with the through hole, and one side surface of the other connection assembly plate 5 is fixedly connected with a plurality of connection long shafts 51 that can pass through the through hole, and the ends of the four connection long shafts 51 located at the four corners are provided with external threaded parts that can be screwed with nuts 52. The insulating busbar sleeve 6 extends upward from the bottom and is provided with an opening for the busbar 2 to be vertically inserted.

[0034] In this embodiment, the support block 7 is fixedly connected to the side of the straight connection plate 3 facing the busbar 2, and the support block 7 is provided with a support groove 71 for the connection long axis 51 to pass through. Since the support block 7 has a certain thickness, it can support the part of the connection long axis 51 that remains suspended, increase the strength of the connection long axis 51, and improve the connection stability.

[0035] The working principle of this embodiment is as follows: first, keep the two bus duct outer plates 1 to be connected to extend the length in the same line as shown in the figure, and fix the straight connecting plates 3 to the respective bus duct outer plates 1 by bolts. Place one of the covering plates 4 under the busbar 2, and fit the upper surface of the pad 41 to the lower surface of the busbar 2, and then put the insulating busbar sleeve 6 on the outside of each busbar 2 from top to bottom. When inserting, the bottom of the insulating busbar sleeve 6 is inserted into the corresponding positioning slot 411, which can ensure that the insulating busbar sleeve 6 is aligned with the perforation on the busbar 2. Then put another covering plate 4 in from above, and when putting it in, the positioning slot 411 of the upper covering plate 4 is engaged with the top of the insulating busbar sleeve 6, which ensures that the vertical arms of the two covering plates 4 are coplanar. Finally, the connection assembly plate 5 is translated from the side so that the connection long axis 51 passes through the perforations on each structure horizontally, and all structures can be connected at the same time. Finally, another perforated connection assembly plate 5 is passed through the other end of the connection long shaft 51, and then the nut 52 is used to fix the connection long shaft 51 with an external threaded portion to complete all the connections. At this time, the two bus duct outer plates 1 are connected to each other, that is, the length of the bus duct is extended. If the length needs to be shortened, the corresponding part can be removed, and no further details will be given here.

[0036] In summary, through the design of the straight connecting plate 3, the covering plate 4, the connecting assembly plate 5, and the insulating busbar sleeve 6, the busbar outer plate 1 and the busbar 2 required for extending the busbar can be fixedly connected at one time, and the operation is convenient; through the design of the support block 7 and the support groove 71 opened thereon, support can be provided for the connecting long axis 51 to increase the strength of the connecting long axis 51; through the design of the pad 41 and the positioning groove 411 opened thereon, the insulating busbar sleeve 6 can be positioned to facilitate the alignment of the perforations between it and other structures, so as to facilitate the traversal of the connecting long axis 51.

[0037] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
