[0002] The inside of the transformer includes components such as an iron core, a coil winding, a voltage regulating switch, and some support structures. Among them, the iron core is fixed by an iron core support, and then the coil is wound on the winding column of the iron core. The voltage regulating switch also needs a corresponding support to be fixed. The existing support structure inside the transformer mainly has the problems of being not simple and irregular. For example, the Chinese patent document with publication number CN209087561U records a transformer on-load voltage regulating switch support. This switch support is connected to multiple support columns by U-shaped bolts. It is not only complex in structure, but also relatively bulky. It is not convenient for the assembly of the transformer, nor is it convenient for the fixation of the leads on the transformer, which will cause confusion in the assembly of related firmware inside the transformer. In order to ensure the effective support and fixation of the transformer voltage regulating switch, and to ensure the assembly quality and operational reliability of the voltage regulating switch and its associated leads, a specially arranged structural member is proposed to meet the above requirements.

A front voltage regulating switch bracket 31 and a rear voltage regulating switch bracket 32 ​​for mounting a voltage regulating switch 3 are respectively provided at the left ends of the front clamping plate 11 and the rear clamping plate 12. The voltage regulating switch 3 is clamped between the front voltage regulating switch bracket 31 and the rear voltage regulating switch bracket 32 ​​and fixed.

[0021] The novel switch bracket and lead clamping structure is provided with a front voltage regulating switch bracket 31 and a rear voltage regulating switch bracket 32 ​​on the side of the core upper clamping plate 1, and the transformer voltage regulating switch 3 is supported and fixed by simple and reasonable structural parts; by providing a wire clamp support plate 4 on the front voltage regulating switch bracket 31, providing a first wire clamp 41 on the wire clamp support plate 4, providing a second wire clamp 42 on the first wire clamp 41, and providing a third wire clamp 43 on the second wire clamp 42, the wires led out of the winding on the transformer core are supported and clamped, and the first wire clamp 41, the second wire clamp 42 and the third wire clamp 43 are installed in a manner that each is separately arranged in space, which is convenient for the arrangement of the leads of each coil, so that the structure for supporting and fixing the voltage regulating switch 3 in the transformer and supporting and clamping the leads of each coil 5 is concise and clear, which is convenient for operators to process, manufacture and assemble the transformer, and the overall appearance of the transformer assembled by the novel switch bracket and lead clamping structure is clear and beautiful, which can reduce the manufacturing cycle and manufacturing cost of the transformer.
