DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] like Figure 1 and Figure 2 As shown, an intermediate connecting insulating sleeve of a multi-phase integral cast insulating busbar comprises two busbars 1 and an insulating sleeve 6, wherein a positioning mechanism 2 is fixedly connected to the middle of the outer surface of the two busbars 1, a locking mechanism 5 is slidably connected to the lower part of the insulating sleeve 6, a connecting assembly 3 is installed on the upper part of the insulating sleeve 6, and a positioning plate 4 is fixedly connected to the side of the upper parts of the two positioning mechanisms 2 that are close to each other and the middle sides of the left and right parts of the upper end of the insulating sleeve 6.

[0033] The busbar 1 in this scheme is a multi-phase integral cast insulated busbar, which is an advanced power distribution equipment that combines the high conductivity of metal conductors and the excellent electrical properties of insulating materials to achieve efficient and safe power transmission;

[0034] Its working principle is: based on the basic principles of current transmission and electrical insulation, the conductor acts as a carrier for current transmission, and the insulating layer cast on the outside of the conductor plays a role in electrical isolation and protection; when current passes through the conductor, the insulating layer can prevent current leakage or short circuit, ensuring the safety and stability of power transmission.

[0035] In the above, after the two busbars 1 are connected together, the positioning plate 4 is lifted by both hands to make the positioning plate 4 drive the device to move, and then the positioning mechanism 2 is placed on the outer surface of the two busbars 1, and the insulating sleeve 6 is placed at the connection between the two busbars 1. After placement, the positioning mechanism 2 is first fixed on the outer surface of the busbar 1. After fixation, the connecting component 3 is pressed to insert the clamping mechanism 5 into the insulating sleeve 6. After the insertion is completed, the connecting component 3 is released to fix the clamping mechanism 5, so that the clamping mechanism 5 is fixed in the insulating sleeve 6, so that the insulating sleeve 6 and the clamping mechanism 5 simultaneously insulate the connection between the two busbars 1.

[0036] In the above, if one wants to remove the insulating sleeve 6 at the connection between the two busbars 1, first press the connecting component 3 to release the fixing of the connecting component 3 on the locking mechanism 5, then take out the locking mechanism 5, and after taking it out, release the positioning of the busbar 1 by the positioning mechanism 2 in turn, and then move the device away through the positioning plate 4, so that the device can realize the function of quick disassembly and quick installation, thereby improving work efficiency.

[0037] In the above, not only the positioning plate 4 can be used to move the device, but also the positioning plate 4 can be used to support the positioning mechanism 2 and the insulating sleeve 6 to each other, so that the positioning mechanism 2 and the insulating sleeve 6 will not shake during installation.

[0038] Further, in order to achieve the purpose of positioning and fixing the outer surface of the busbar 1 by the positioning mechanism 2, refer to Figure 3 The positioning mechanism 2 includes a positioning clamp 21 and a positioning frame 23. The positioning clamp 21 is attached to the middle part of the upper end of the busbar 1, and the positioning frame 23 is attached to the middle part of the lower end of the busbar 1. Threaded holes are provided in the front and rear middle sides of the upper end of the positioning clamp 21, and threaded grooves are provided in the front and rear middle sides of the upper end of the positioning frame 23. The threaded holes and the inner cavities of the threaded grooves on the same side are threadedly connected with screws 22.

[0039] In the above, the first positioning clamp 21 is first placed in the middle of the upper end of the busbar 1 so that it fits the busbar 1, and then the second positioning frame 23 is placed in the middle of the lower end of the busbar 1 so that it also fits the busbar 1. Finally, the screw 22 is screwed into the threaded holes and threaded grooves provided in the first positioning clamp 21 and the second positioning frame 23, so that the first positioning clamp 21 and the second positioning frame 23 clamp and fix the busbar 1;

[0040] In the above, when they need to be separated, the screw 22 only needs to be screwed in the reverse direction to separate the positioning clamp 1 21 and the positioning frame 2 23, so that quick disassembly and quick assembly can be achieved.

[0041] Further, in order to achieve the purpose of the connection assembly 3 to engage the engaging mechanism 5 in the insulating sleeve 6, refer to Figure 4 , Figure 5 and Figure 6 The connecting assembly 3 includes four transmission mechanisms 33, which are respectively slidably connected to the left and right sides of the front and rear parts of the insulating sleeve 6, and the upper parts of the four transmission mechanisms 33 are commonly fixedly connected to a transmission frame 32, and the middle part of the upper end of the transmission frame 32 is fixedly connected to a pressing plate 31;

[0042] The transmission mechanism 33 includes a slide groove 336 and a spur gear 334. The slide groove 336 is provided inside the insulating sleeve 6. A rack 331 is slidably connected to the inner cavity of the slide groove 336. A rectangular plate 333 is fixedly connected to the upper left side of the inner cavity of the slide groove 336. A compression spring 332 is fixedly connected between the left side of the lower end of the pressure plate 31 and the upper end of the rectangular plate 333. The spur gear 334 is rotatably connected to the lower left side of the inner cavity of the slide groove 336. A threaded rod 335 is threadedly connected to the inner cavity of the spur gear 334.

[0043] The spur gear 334 is meshed with the rack gear 331 , and the transmission frame 32 is fixedly connected to the upper ends of the four rack gears 331 .

[0044] In the above, by pressing the pressing plate 31, the pressing plate 31 drives the transmission frame 32 to move downward. When the transmission frame 32 moves downward, it drives the rack 331 to slide in the inner cavity of the slide groove 336. When the rack 331 slides downward, it drives the spur gear 334 to rotate. The spur gear 334 is threadedly connected with the threaded rod 335, so that when the spur gear 334 rotates, it drives the threaded rod 335 to move into the insulating sleeve 6, and then the locking mechanism 5 is inserted into the insulating sleeve 6.

[0045] In the above, when the rack 331 moves downward, the compression spring 332 is compressed by the rectangular plate 333 to generate pressure. After the locking mechanism 5 is inserted into the insulating sleeve 6, the pressure plate 31 is released to release the pressure on the rack 331. After the pressure on the rack 331 is released, the compression spring 332 will release the pressure and push the rack 331 to move upward. When the rack 331 moves upward, it will drive the spur gear 334 to rotate, so that the threaded rod 335 moves outward, and the locking mechanism 5 is clamped in the insulating sleeve 6.

[0046] Further, in order to provide insulation protection for the connection of the busbar 1 by the clamping mechanism 5 and the insulating sleeve 6, see Figure 7 The clamping mechanism 5 includes a convex plate 53, which is attached to the lower end of the insulating sleeve 6. The front and rear parts of the upper end of the convex plate 53 are respectively fixedly connected with the clamping plate 52. The upper end of the convex plate 53 is provided with four circular grooves, and the inner cavities of the four circular grooves are all fixedly connected with circular shells 56. The inner cavities of the four circular shells 56 are all slidably connected with telescopic columns 55. A rebound spring 54 is fixedly connected between the lower end of the telescopic column 55 and the top wall of the circular shell 56 on the same side, and the upper ends of the four telescopic columns 55 are fixedly connected with the insulating plate 51.

[0047] A plurality of circular holes are formed on the vertical surfaces of the two engaging plates 52 , and the threaded rods 335 slide in the inner cavities of the circular holes.

[0048] In the above, by pushing the convex plate 53 upward, the convex plate 53 drives the snap plate 52 to move upward, and the snap plate 52 is inserted into the insulating sleeve 6 and then fixed inside the insulating sleeve 6 through the circular hole and the threaded rod 335, so that the insulating plate 51 is attached to the lower part of the connection of the busbar 1 for insulation protection.

[0049] In the above, by designing the multiple holes on the clamping plate 52, the device can be applied to busbars of different sizes. With the support of the rebound spring 54, the telescopic column 55 and the circular shell 56, the telescopic column 55 can always fit the lower part of the connection of the busbar 1;

[0050] The principle is as follows: when the insulating plate 51 contacts the lower part of the connection of the busbar 1, it will move downward. When the insulating plate 51 moves downward, it will drive the telescopic column 55 downward in the inner cavity of the circular shell 56. When the telescopic column 55 moves downward, it will compress the rebound spring 54 to generate pressure, so that the insulating plate 51 can be tightly attached to the lower part of the connection of the busbar 1, so that the insulating plate 51 can fit busbars 1 of different sizes, thereby improving the practicability of the device.

[0051] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
