[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, a highly integrated power distributor includes an upper shell 1, which is detachably arranged inside a lower shell 2. A plurality of connectors 3 are detachably arranged on the top surface of the upper shell 1. Two conductive sheets 4 are arranged inside the lower shell 2. The left conductive sheet 4 is provided with a negative electrode 5, the right conductive sheet 4 is provided with a positive electrode 6, and the right conductive sheet 4 is provided with a ground wire 7. Two mounting grooves 8 are provided on the top surface of the lower shell 2. Two mounting plates 9 are fixed to the bottom surface of the upper shell 1. The outer sides of the two mounting plates 9 are respectively provided with fixing grooves 10. The two mounting plates 9 are respectively detachably arranged in the two mounting grooves 8, the front and rear sides of the outer wall of the lower shell 2 are respectively provided with fixing holes 11, the interiors of the two fixing holes 11 are respectively slidably inserted with fixing shafts 12, the two fixing shafts 12 are respectively slidably inserted in the two fixing grooves 10, the outer ends of the two fixing shafts 12 are respectively fixed with stoppers 13, the front and rear sides of the outer wall of the lower shell 2 are respectively fixed with springs 14, the two springs 14 are respectively wrapped around the two fixing shafts 12, and the outer ends of the two springs 14 are respectively fixedly connected to the inner sides of the two stoppers 13.

[0024] During use, when the staff needs to install the conductive sheet 4, they first place the conductive sheet 4 inside the lower shell 2, then pull the stopper 13 toward the outside, driving the fixed shaft 12 to move outward. At this time, the spring 14 is in a stretched state, and then the upper shell 1 is fitted with the lower shell 2 so that the mounting plate 9 is inserted into the mounting groove 8. Then, the stopper 13 is released, and the fixed shaft 12 can be automatically reset by the spring 14, so that the fixed shaft 12 is slidably inserted into the fixed groove 10, completing the installation of the conductive sheet 4; conversely, when the staff needs to disassemble the conductive sheet 4, they first pull the stopper 13 toward the outside so that the fixed shaft 12 is away from the inside of the fixed groove 10, and the upper shell 1 can be separated from the lower shell 2, and the conductive sheet 4 inside the lower shell 2 can be taken out.

[0025] The mounting plate 9, the fixed shaft 12, the block 13 and the spring 14 facilitate the staff to disassemble and assemble the upper shell 1, the lower shell 2 and the conductive sheet 4, and facilitate the regular inspection and maintenance of the conductive sheet 4, thereby reducing the maintenance cost of the conductive sheet 4 and ensuring the long-term stable operation of the power distributor.

[0026] like Figures 1-4 As shown, two positioning posts 15 are fixed on the bottom surface of the upper shell 1 , and two positioning grooves 16 are provided on the top surface of the lower shell 2 . The two positioning grooves 16 respectively position the two positioning posts 15 .

[0027] During use, the positioning columns 15 and the positioning grooves 16 facilitate the staff to assist in positioning when fitting the upper shell 1 and the lower shell 2 together, ensuring the precise alignment of the upper shell 1 and the lower shell 2 during the assembly process and avoiding installation problems caused by misalignment.

[0028] like Figures 1-4 As shown, a plurality of limiting columns 17 are fixed to the inner bottom surface of the lower shell 2, and the plurality of limiting columns 17 respectively limit the two conductive plates 4. A plurality of threaded grooves 18 are provided on the top surface of the upper shell 1, and a plurality of fixing plates 19 are respectively fixed on the front sides of the plurality of connecting parts 3. The top surfaces of the plurality of fixing plates 19 are respectively provided with threaded holes 20, and bolts 21 are respectively threadedly connected in the plurality of threaded holes 20, and the threaded ends of the plurality of bolts 21 are respectively threadedly connected to the internal threads of the plurality of threaded grooves 18.

[0029] During use, the limiting posts 17 facilitate the positioning of the conductive sheet 4, ensuring that the conductive sheet 4 is correctly positioned within the lower housing 2, preventing the conductive sheet 4 from shifting or tilting during use. This helps maintain good contact between the conductive sheet 4 and the upper housing 1 or other components, ensuring stable current transmission. By matching the threaded holes 20 on the fixing plate 19 with the threaded grooves 18 on the top surface of the upper housing 1 and fastening them with bolts 21, workers can easily install or remove the connector 3 from the upper housing 1, making replacement or adjustment of the connector 3 simple and quick.

[0030] like Figures 1-4 As shown, a sealing gasket 22 is fixed to the bottom surface of the upper shell 1, and the thickness of the sealing gasket 22 is 1 mm.

[0031] During use, the sealing gasket 22 helps isolate the gap between the upper and lower housings 1 and 2, preventing dust, moisture, and other foreign matter from entering the power distributor, thereby extending the power distributor's service life and reliability. Setting the thickness of the sealing gasket 22 to 1 mm ensures a good seal while avoiding assembly difficulties caused by an excessively thick gasket or a poor seal caused by an excessively thin gasket.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
