Generally, the transformer will have multiple terminals, including input terminals and output terminals, which are used to connect power lines, load devices and ground lines to ensure that the transformer works normally and converts the voltage appropriately.

[0028] In the field of power transmission and distribution, transformers are typically installed at high altitudes to ensure safety and avoid ground interference. However, this installation method poses significant risks to workers performing wiring operations at height. Especially in traditional structures, terminals are fixed and connected using bolts, requiring individual tightening and loosening, which is not only time-consuming and labor-intensive but also demands prolonged, precise work at height, greatly increasing safety hazards. Furthermore, space constraints and inconvenient tool operation result in low wiring efficiency, high labor intensity, and a high risk of accidents due to improper operation. Therefore, there is an urgent need to improve the wiring structure and adopt a faster and safer connection method to reduce the risks of working at heights and improve work efficiency and safety. This solution replaces the traditional bolt fixing method with a quick-connect terminal structure, significantly improving the installation efficiency of transformer wiring and enhancing operational convenience and safety. This connection method allows for quick plugging and locking without the need for complex tools, reducing working time at heights, lowering construction difficulty, and reducing the risk of electric shock or falls. Simultaneously, the stable and reliable structural design ensures a secure electrical connection, making it suitable for various power transmission and distribution scenarios and effectively improving on-site safety and work efficiency.
[0029] Instructions for use: When it is necessary to install the external terminal inside the transformer's built-in mounting bracket 1 and connect it to the built-in terminal 2, first align the external terminal 3 with the built-in terminal 2 and insert it into the transformer's built-in mounting bracket 1. Then, start the motor 5 to rotate the threaded rod 6. The thread groove on the outer surface of the threaded rod 6 is a bidirectional thread groove. Therefore, when the threaded rod 6 rotates, the threaded sleeves 7 connected by the helical drive on both sides of the outer surface of the threaded rod 6 will move towards each other, and will carry the connecting rods 8 on both sides to move. The connecting rods 8 on the same side are rotatably connected to the top block 10 on the corresponding crossbar 9. Therefore, the two sets of crossbars 9 will be driven to move to both sides. The crossbars 9 moving outward will be driven by the spring 12 and the slide rail 13 to move the crossbar 14 outward. The clamping block 15 on the crossbar 14 will first engage with the inner groove 4 on the external terminal 3. Simultaneously, the rack 11 on the crossbar 14 will move outward. Displacement occurs as rack 11 meshes with gear 19, which in turn meshes with rack 17. Consequently, rack 17 moves in the opposite direction under the action of gear 19 and rack 11, driving the clamping block 20 at the end of rack 17 to insert into the inner groove 4 and be fixed in conjunction with clamping block 15. Simultaneously, as the crossbar 9 continues to advance, it compresses spring 12. The crossbar 14, clamping block 15, and clamping block 20 remain in the same position. The crossbar 9 then pushes the transmission column 21 to move, and the connecting piece 22 at the end of the transmission column 21 moves synchronously. One end of the transmission rod 24 is rotatably connected to the connecting piece 22, thus pushing the transmission rod 24 to move. The fixing rod 23 is slidably connected to the sliding groove 25 on the transmission rod 24, which guides the direction of displacement of the transmission rod 24, thereby causing the fixing plate 26 at the other end of the transmission rod 24 to engage in the fixing groove 27, thereby enhancing the fixing effect on the external terminal 3.
