DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the drawings and embodiments.

[0028] The transformer bushing assembly has a conductive rod 1, a jacket 2, a copper spatula 3, copper sheets 4, slide bars 5, threaded rods 7, adjusting pieces 8 and linkage arms 10;

[0029] As Figures 1 to 4 shown, the conductive rod 1 is used for current transmission. A jacket 2 is sleeved on the top end of the conductive rod 1. A copper spatula 3 is provided on one side of the jacket 2. The bottom of the copper spatula 3 bends and extends to be connected with the jacket 2. Copper sheets 4 are symmetrically provided on one side of the copper spatula 3. Slide bars 5 are slidably inserted at the four corners of the copper spatula 3. One end of each slide bar 5 penetrates through the copper sheet 4 and is fixedly connected with a round plate 6. The round plate 6 presses the copper sheet 4 to be in fit with the copper spatula 3. Threaded rods 7 are symmetrically rotatably connected to the other side of the copper spatula 3. An adjusting piece 8 is sleeved on the outer side of the threaded rod 7, and a threaded cylinder 9 is fixedly connected inside the adjusting piece 8. The threaded cylinder 9 is threadedly connected to the outer side of the threaded rod 7. The other ends of the slide bars 5 are symmetrically rotatably connected with linkage arms 10. One end of each linkage arm 10 is rotatably and slidably connected with the corresponding adjusting piece 8.

[0030] The electrical conductivity of the conductive rod 1 enables the smooth transmission of electrical energy, providing necessary power support for the entire transformer bushing assembly. The jacket 2 is tightly sleeved on the top end of the conductive rod 1, playing a role of fixation and support. When connecting electricity, the end of the wire can be inserted between the copper spatula 3 and the copper sheet 4. Through the tight fit of the copper spatula 3 and the copper sheet 4, the physical fixation and electrical connection of the wire are realized. The rotation of the threaded rod 7 drives the adjusting piece 8 sleeved on its outer side to move together. The threaded cylinder 9 inside the adjusting piece 8 is threadedly connected to the threaded rod 7, ensuring the accuracy and stability of the adjustment. When the adjusting piece 8 moves, it will push or pull the slide bar 5 through the linkage arm 10, thereby changing the pressing force of the round plate 6 on the copper sheet 4 and realizing the precise adjustment of the tightness of the electrical connection.

[0031] As Figures 1 to 4 shown, one end of the linkage arm 10 is designed as a round surface, and this round surface is eccentrically rotatably connected with the corresponding slide bar 5. One edge of one end of the linkage arm 10 is in pressing contact with the copper spatula 3.

[0032] During the rotation of the linkage arm 10, due to the effect of the eccentric rotational connection, the end of the linkage arm 10 will gradually reduce the pressing force. Further rotation will also cause the end of the linkage arm 10 to separate from the copper spatula 3, allowing the copper spatula 3 and the copper sheet 4 to have a certain sliding space on the slide bar 5, reducing the pressing force of the round plate 6 on the copper sheet 4, and allowing the wire to be inserted between the round plate 6 and the copper sheet 4.

[0033] As Figures 1 to 4 shown, a sliding cavity is opened inside the adjusting piece 8, and connecting rods 11 are symmetrically and slidably connected inside the sliding cavity. The two ends of each connecting rod 11 are fixedly connected with the corresponding linkage arm 10.

[0034] When the adjusting piece 8 moves along the thread direction driven by the threaded rod 7, it transmits this movement to the linkage arm 10 through the connecting rod 11 in the sliding cavity. As a bridge between the connecting rod 11 and the sliding rod 5, the linkage arm 10 will rotate accordingly according to the movement direction of the connecting rod 11, and the connecting rod 11 slides correspondingly in the sliding cavity along with the rotation of the linkage arm 10.

[0035] As Figures 1 to 4 shown, the length of the adjusting piece 8 is less than the vertical distance between the two sliding rods 5 arranged up and down of the copper shovel 3, ensuring that the adjusting piece 8 will not be blocked by the sliding rod 5 when moving outside the threaded rod 7.

[0036] As Figures 1 to 4 shown, one end of the threaded rod 7 is fixedly connected with a knob 12, which makes it more labor-saving and convenient to rotate and adjust the threaded rod 7.

[0037] As Figures 1 to 4 shown, the central area on the side of the copper shovel 3 opposite to the copper sheet 4 is relatively arc-shaped in bending, jointly enclosing a circular inner cavity. When the end of the wire is inserted into this circular cavity, the copper shovel 3 and the copper sheet 4 can closely fit the wire through the relatively arc-shaped design in bending, realizing the physical fixation and electrical connection of the wire.

[0038] As Figures 1 to 4 shown, bolts 13 are symmetrically and slidably inserted inside the jacket 2. The jacket 2 forms a stable connection with the conductive rod 1 through the bolts 13 slidably inserted inside. This design ensures the stability and reliability of the conductive rod 1, and also facilitates adjusting the tightness of the jacket 2 through the bolts 13.

[0039] As Figures 1 to 4 shown, porcelain insulators 14 are equidistantly installed on the outer side of the conductive rod 1, and nuts 15 are threadedly connected to the outer sides of both ends of the conductive rod 1. The porcelain insulators 14 have good electrical insulation performance, which can prevent current leakage or short circuit during transmission, ensuring the safe operation of the transformer. The nuts 15 are used to fix the porcelain insulators 14, enhancing the structural stability and the reliability of the electrical connection.

[0040] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
