Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to a rectangular busbar fixing hardware. Background Art

[0002] Busbar fixtures are commonly used electrical hardware used to secure busbars. Patent application number 201721378065.5 discloses a novel busbar fixture comprising a fixing plate, a balancing plate disposed beneath the fixing plate, the fixing plate and the balancing plate interconnected, and connecting bolts disposed on the balancing plate. A connecting cavity is defined between the fixing plates, and an extrusion plate is disposed within the connecting cavity. The extrusion plate is provided with wear-resistant protrusions that facilitate the connection and fixation of the fixture, making it more convenient to secure the fixture. However, the distance between the two fixing plates makes it difficult to close together to clamp the busbar, causing the busbar to wobble. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a rectangular busbar fixing hardware in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a rectangular busbar fixing hardware, including a base, a countersunk hole is provided in the middle of the base, and the countersunk bolt passes through the countersunk hole, threaded holes are provided on both sides of the base, and a V-shaped groove is provided on the top surface of the base. It also includes two L-shaped clamps, and the L-shaped clamps include a vertical plate and a horizontal plate located on the outside of its bottom, and a long hole is provided on the horizontal plate, and the first fastening bolt is connected to the threaded hole after passing through the long hole. The bottom surface of the horizontal plate is an inclined surface, and when the inclined surface is in contact with one side of the V-shaped groove, the extension direction of the vertical plate is perpendicular to the bottom surface of the base, and a through hole is provided on the top of the vertical plate, and the second fastening bolt is connected to the nut after passing through the two through holes.

[0005] Preferably, the axis of the countersunk hole is on the symmetry plane of the V-shaped groove.

[0006] Preferably, reinforcing ribs are provided on both sides of the L-shaped splint.

[0007] Preferably, it further comprises a sleeve, which is sleeved on the outside of the second fastening bolt.

[0008] Compared with the prior art, the present invention has the following advantages: a V-shaped groove is provided on the top surface of the base, and the bottom surface of the horizontal plate on the L-shaped clamp is an inclined surface. When the first fastening bolt passes through the long hole on the horizontal plate and is connected with the threaded hole on the base, tightening the first fastening bolt can make the two L-shaped clamps move closer together, thereby clamping the rectangular busbar, and the rectangular busbar is not easy to shake.

[0012] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0013] Specific implementation method: Figure 1-2 As shown, a rectangular busbar fixing hardware comprises a base 1, a countersunk hole is provided in the middle of the base 1, a countersunk bolt 2 passes through the countersunk hole, threaded holes 12 are provided on both sides of the base 1, a V-shaped groove 11 is provided on the top surface of the base 1, and both sides of the V-shaped groove 11 are inclined. It also comprises two L-shaped clamping plates 6, the L-shaped clamping plates 6 comprise a vertical plate 61 and a horizontal plate 62 located outside the bottom thereof, a long hole 621 is provided on the horizontal plate 62, a first fastening bolt 3 passes through the long hole 621 and is connected to the threaded hole 12, and can be fastened between the head of the first fastening bolt 3 and the horizontal plate 6 2, a gasket and a spring ring are arranged between the horizontal plate 62, the bottom surface of the horizontal plate 62 is an inclined surface 622, and the inclined surface 622 is inclined with the inner side surface of the vertical plate 61. When the inclined surface 622 is in contact with one side of the V-shaped groove 11, the extension direction of the vertical plate 61 is perpendicular to the bottom surface of the base 1. At this time, the inner side surface of the vertical plate 61 is parallel to the symmetry plane of the V-shaped groove 11 and perpendicular to the bottom surface of the base 1. When the first fastening bolt 3 is tightened, the L-shaped clamping plate 6 will slide to the bottom of the V-shaped groove 11. A through hole 611 is provided at the top of the vertical plate 61, and the second fastening bolt 4 passes through the two through holes 611 and is connected with the nut. When in use, first connect the countersunk bolt 2 to the insulator on the power facility, then connect the two L-shaped clamps 6 to the base 1, do not tighten the first fastening bolt 3, then place the rectangular busbar between the two L-shaped clamps 6, and then tighten the two first fastening bolts 3. The two L-shaped clamps 6 will move closer together to clamp the rectangular busbar, and then pass the second fastening bolt 4 through the two through holes 611 in turn and connect it to the nut, so that the vertical plate 61 also has a good clamping effect on the top of the rectangular busbar, so that the rectangular busbar is not easy to shake.

[0014] Preferably, the axis of the countersunk hole is on the symmetry plane of the V-shaped groove 11.

[0015] Preferably, reinforcing ribs 63 are provided on both sides of the L-shaped clamping plate 6 to improve the strength and heat dissipation capacity of the L-shaped clamping plate 6 .

[0016] Preferably, a sleeve 5 is further included, which is sleeved outside the second fastening bolt 4. The length of the sleeve 5 is slightly smaller than the thickness of the rectangular busbar. The sleeve 5 can prevent the rectangular busbar from directly contacting the threads of the second fastening bolt 4, thereby preventing the threads from leaving marks.

[0017] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
