Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Embodiment 1

[0029] As Figures 1 - 5 shown: This embodiment provides a connector, which includes a fastening screw 11, an insulating component, and a plurality of conductive bars 7. A nut 1 is threadedly connected to the end of the fastening screw 11. A sleeve 9 is sleeved on the fastening screw 11. Insulating side plates 8 are provided on one or both sides of the insulating component. The insulating side plates 8 and a plurality of insulating middle plates 6 are all sleeved on the sleeve 9 and can be fixed circumferentially along the sleeve 9. Conductive bars 7 are fixed on both side surfaces of the insulating middle plate 6, and a conductive bar 7 is fixed on the side surface of the insulating side plate 8 close to the insulating middle plate 6. Any two oppositely arranged conductive bars 7 are used to clamp and fix the copper bar 16 of the busbar 14. When the insulating side plate 8 is provided on one side of the insulating component, the conductive bar 7 provided on the outside of the edge insulating middle plate 6 is used to connect the ground wire. Specifically as Figure 1 shown, the insulating side plate 8, the conductive bar 7, and the insulating middle plate 6 are all bent plates. Preferably, the included angle between the first bent part and the second bent part is 90°, 120°, or 150°. The insulating side plate 8, the conductive bar 7, and the insulating middle plate 6 are all aligned and stacked. The insulating middle plate 6, the conductive bar 7, and the first bent part and the second bent part of the insulating side plate 8 each clamp and fix a busbar 14. The number of insulating middle plates 6 can be reasonably set according to the number of copper bars 16 of the busbar 14. In this embodiment, the insulating middle plate 6 is preferably three. Grooves 12 are opened on both side surfaces of the insulating middle plate 6 and on one side surface of the insulating side plate 8. Clamping protrusions 13 are provided at the edges of the grooves 12. The outer shape of the conductive bar 7 matches the grooves 12 and the clamping protrusions 13. Specifically as Figure 4 shown, chamfered edges are provided at the ends of the first bent part and the second bent part of the conductive bar 7, so that the conductive bar 7 is clamped and fixed in the groove 12.

[0030] The sleeve 9 is preferably a hexagonal tube. Hexagonal through holes are opened on the insulating side plate 8, the conductive bar 7, and the insulating middle plate 6. The hexagonal through holes match the hexagonal tube, so as to realize the circumferential fixation of the insulating side plate 8, the conductive bar 7, and the insulating middle plate 6 by using the matching hexagonal through holes and the hexagonal tube, and enable the insulating side plate 8, the conductive bar 7, and the insulating middle plate 6 to slide axially on the hexagonal tube to facilitate the clamping and fixation of the copper bar 16.

[0031] This embodiment may further include an upper side plate 4 and a lower side plate 10. Both the upper side plate 4 and the lower side plate 10 are formed by welding aluminum profiles, or both the upper side plate 4 and the lower side plate 10 are integrally formed using aluminum plates or steel plates to achieve good heat dissipation effects. Both the upper side plate 4 and the lower side plate 10 are sleeved on the hexagonal tube. The upper side plate 4 is located above the upper insulating side plate 8 and there is a first spacer 5 between the upper side plate 4 and the upper insulating side plate 8. The lower side plate 10 is located below the lower insulating side plate 8 and there is a second spacer 5 between the lower side plate 10 and the lower insulating side plate 8. The inner sides of the first spacer 5 and the second spacer 5 are both matched with the hexagonal tube. The outer sides of the first spacer 5 and the second spacer 5 are both provided with a convex part and a connecting part. The convex part of the first spacer 5 is located between the upper side plate 4 and the upper insulating side plate 8, and the connecting part of the first spacer 5 is matched with the fixing hole of the upper side plate 4. The convex part of the second spacer 5 is located between the lower side plate 10 and the lower insulating side plate 8, and the connecting part of the second spacer 5 is matched with the fixing hole of the lower side plate 10. Thus, a distance is separated between the upper side plate 4 and the adjacent insulating middle plate 6, and a distance is separated between the lower side plate 10 and the insulating side plate 8, which helps the copper busbar 16 dissipate heat. At the same time, when tightening the nut 1 to axially fix each insulating middle plate 6 and insulating side plate 8, it is avoided that the nut 1 and the nut of the fastening screw 11 directly contact each insulating middle plate 6 and insulating side plate 8, avoiding damage to the insulating middle plate 6 and insulating side plate 8. Limiting blocks 18 are provided on the inner surfaces of the upper side plate 4 and the lower side plate 10, specifically as Figure 1 and Figure 2 shown. The limiting blocks 18 are all used to limit the upper plate and the lower plate of the busbar trunking 14. The specific positions after limiting are as Figure 6 shown. After the upper side plate 4 and the lower side plate 10 limit the two busbar trunkings 14, the included angle formed by the two busbar trunkings 14 is equal to the included angle of the bending plate.

[0032] Two sealing rings 3 and two bowl gaskets 2 are sleeved on the fastening screw 11. One sealing ring 3 and one bowl gasket 2 are arranged between the nut 1 and the upper side plate 4, and the other sealing ring 3 and the other bowl gasket 2 are arranged between the lower side plate 10 and the nut of the fastening screw 11. The nut 1 is a square nut to prevent water from spreading from the hexagonal tube to each insulating middle plate 6, conductive busbar 7, and insulating side plate 8. Additionally, in this embodiment, "upper" and "lower" refer to the direction where the square nut is located as "upper" and the direction where the nut of the fastening screw 11 is located as "lower".

[0033] It should be noted that there may be one insulating side plate 8. Thus, in this embodiment, four insulating middle plates 6 are provided, and the conductive busbar 7 is fixed only on one side of the insulating middle plate 6 adjacent to the spacer 5, that is, the conductive busbar 7 is not provided on the side adjacent to the spacer 5.

[0034] Embodiment Two

[0035] As Figures 6 - 7As shown in the figure: This embodiment provides a special-shaped busway, which includes two busways 14 and the connector in the first embodiment. One busway 14 is clamped and fixed at each end of the connector, and the copper bars 16 of the busway 14 are inserted and pressed tightly into the connector, so as to be directly clamped and fixed by the connector, forming a special-shaped busway, eliminating the cutting and welding processes for the shell and copper bars of the busway 14 in the traditional method, improving the production quality and production efficiency, and reducing the processing difficulty. One of the preferred solutions is that the inner sides of the two busways 14 are fixedly connected by an inner connecting plate 15 and bolts, and the outer sides of the two busways 14 are fixedly connected by an outer connecting plate 17 and bolts.

[0036] Specific examples are used in this specification to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
