[0003] However, since the screw portion of the fastening bolt is circular, the side plate and the insulating partition will rotate on the surface of the fastening bolt. When installing it between two dense bus ducts, the insulating partition needs to be adjusted, which brings inconvenience to the installation.

[0004] A bus duct connector disclosed in the announcement number CN220234136U is provided with a hexagonal insulating partition tube and a side plate insulating tube, and the side plate insulating tube includes a hexagonal tube head, so that the insulating partition will not rotate at any time, thereby improving the assembly efficiency. However, while solving the problem, the bus duct connector has the following defects:

[0005] The hexagonal insulating spacer and the hexagonal tube head are plugged into each other, and the hexagonal insulating spacer and the partition are slidably plugged together. Before installation, there is a certain gap between multiple partitions. Therefore, the hexagonal insulating spacer and the hexagonal tube head will slide against each other, causing the insulating spacer to separate from the side panel insulating tube, or the side panel insulating tube to separate from the connector side panel, so that the partition will still rotate during installation, which will still affect the installation efficiency. Utility Model Content

A limiting bolt is inserted into the inside of the through hole, and the groove is sleeved on the outer surface of the limiting bolt, and the end of the limiting bolt is threadedly connected to the limiting nut.

[0009] Preferably, any of the above schemes is that a first connecting hole is opened in the middle of one side of the side panel, a second connecting hole is opened in the middle of one side of the insulating partition, and an avoidance hole is opened in the middle of one side of the connecting plate, a fastening bolt is inserted into the inside of the first connecting hole, and the fastening bolt passes through the second connecting hole and the avoidance hole, and a square nut is threadedly connected to the outer surface of the fastening bolt, and the width of the square nut is equal to the width of the opening.

[0011] Preferably, any of the above schemes has an insulating tube fixedly connected to one side of the side plate close to the insulating partition, and the insulating tube corresponds to the position of the first connecting hole, and the diameter of the second connecting hole is greater than or equal to the outer diameter of the insulating tube, so as to prevent the busbar of the bus duct from contacting the fastening bolts.

[0012] Preferably, any of the above schemes has a positioning groove on the side of the insulating partition, and the connecting piece is fixedly connected in the positioning groove, which facilitates the positioning of the connecting piece during production and assembly.

[0032] Specifically, Figure 1-5 As shown, a first connecting hole 14 is opened in the middle of one side of the side plate 1, a second connecting hole 22 is opened in the middle of one side of the insulating partition 2, and an avoidance hole 31 is opened in the middle of one side of the connecting plate 3. A fastening bolt 4 is inserted into the inside of the first connecting hole 14, and the fastening bolt 4 passes through the second connecting hole 22 and the avoidance hole 31. The outer surface of the fastening bolt 4 is threadedly connected with a square nut 41, and the width of the square nut 41 is equal to the width of the opening 12. The square nut 41 is stuck in the opening 12, so that the side plate 1 and the insulating partition 2 can be fastened by directly rotating the fastening bolt 4.

[0034] Preferably, Figure 4 As shown, the fastening bolt 4 needs to be inserted into the second connecting hole 22. By making the diameter of the avoidance hole 31 larger than the diameter of the second connecting hole 22, the connection sheet 3 can be prevented from contacting the fastening bolt 4, thereby avoiding the problem of the fastening bolt 4 being conductive.

[0035] Embodiment 2:

The insulating tube 15 is inserted into the second connecting hole 22 of an insulating partition 2 adjacent to the side plate 1, so that when connected to the bus duct, after a busbar at the edge of the busbar row collides with the insulating tube 15, the busbar row cannot continue to approach the fastening bolt 4, thereby avoiding the contact between the busbar row and the fastening bolt 4, resulting in the problem of conductivity of the fastening bolt 4.

[0037] Embodiment three:

[0038] like Figure 4 As shown, based on the first or second embodiment, a positioning groove 23 is provided on the side of the insulating partition 2, and the connecting piece 3 is fixedly connected in the positioning groove 23. When processing the connector, the setting of the positioning groove 23 facilitates the centering of the connecting piece 3.

[0039] The working principle of the utility model is as follows: when assembling, put the bowl mat 5 into the slide groove 11, insert the fastening bolt 4 and the limiting bolt 6 into the first connecting hole 14 and the through hole 13 of one side plate 1 respectively, then put the side plate 1 flat on the table, fastening bolt 4 and limiting bolt 6 are perpendicular to the table, then a plurality of insulating partitions 2 fixed with connecting pieces 3 and another side plate 1 are sequentially sleeved on the fastening bolt 4 and limiting bolt 6, finally, the limiting nut 61 is threadedly connected to the end of the limiting bolt 6, and the square nut 41 is threadedly connected to the surface of the fastening bolt 4;

[0040] When the device is installed between two bus ducts, the busbar is inserted between multiple insulating partitions 2, and then the square nut 41 is pushed to make it stuck in the opening 12, and then the torque wrench is used to rotate the fastening bolt 4 so that the fastening bolt 4 and the square nut 41 clamp the two side plates 1 through the bowl gasket 5, so that the side plates 1 and the insulating partitions 2 are close to each other, and finally the busbar is clamped.

[0042] 1. By setting the limiting bolt 6, it is inserted into the through hole 13 on the side plate 1, and the groove 21 on the insulating partition 2 is sleeved on the outer surface of the limiting bolt 6, so that the side plate 1 and the insulating partition 2 cannot rotate relative to each other. Therefore, during installation, there is no need to rotate and adjust the side plate 1 and the insulating partition 2, thereby improving the installation efficiency.

[0043] 2.

[0044] 3. By setting the insulating tube 15, the insulating tube 15 is inserted into the second connecting hole 22, and the fastening bolt 4 is inserted into the insulating tube 15. Therefore, the fastening bolt 4 will not directly contact the inner wall of the second connecting hole 22, so that when the fastening bolt 4 is rotated, the outer surface of the fastening bolt 4 can be avoided from being worn, resulting in the problem of damage to the insulating layer on its surface. When connected to the busbar, after a busbar at the edge of the busbar hits the insulating tube 15, the busbar cannot continue to approach the fastening bolt 4, thereby avoiding the contact between the busbar and the fastening bolt 4, resulting in the problem of conductivity of the fastening bolt 4.

[0045] 4. By setting a positioning groove 23 on the side of the insulating partition 2, during production, the connecting piece 3 can be centrally positioned by simply fixing the connecting piece 3 in the positioning groove 23, thereby facilitating the positioning of the connecting piece 3 and achieving the purpose of facilitating production.
