[0005] To solve the above technical problem, the embodiments of the utility model propose a silicone rubber transformer that is convenient for installation, including a coil, copper terminals, and further including a tapping plate, an upper end ring, a lower end ring, and nylon bolts. The upper end ring and the lower end ring are respectively arranged at the upper and lower ends of the coil. Assembly countersunk holes are provided on one side of the upper end ring and the lower end ring. Upper connection parts and lower connection parts are respectively provided at the upper and lower ends of the tapping plate. Assembly holes corresponding to the assembly countersunk holes of the upper end ring and the lower end ring are respectively provided on the upper connection parts and the lower connection parts. The upper connection part and the upper end ring, and the lower connection part and the lower end ring are fixedly connected by nylon bolts. The copper terminals are arranged on the tapping plate, and a silicone rubber layer is correspondingly provided on the surface layer of the coil.

[0006] Further, clamping grooves corresponding to the tapping plate are provided on the lower side of the upper end ring and the upper side of the lower end ring.

[0007] Further, an identification hole is provided on one side of the upper end ring.

[0008] Further, a plurality of terminal assembly holes corresponding to the copper terminals are provided on the tapping plate.

[0009] The beneficial effects of the utility model are as follows: The utility model can conveniently and quickly install the combination of the tapping plate and the end ring, improving the production efficiency; the tapping plate of the utility model is convenient for strengthening the copper terminals, and the identification hole can facilitate users to quickly identify and prevent reverse installation; the nylon bolts of the utility model ensure the insulation performance of the product.
