[0034] see figure 1 and Figure 4 As shown, the present invention provides a shielding ring structure at the sharp corner of the transformer opening, which includes a shielding ring 1 and two fixing plates 2 symmetrically welded on both sides of the shielding ring.
[0035] The section of the shielding ring 1 is a semi-circular structure, so that the surface facing the lead wire and the coil is a circular ring, the surface is smooth, and the shape of the electrode is good.
[0036] The shielding ring 1 can be designed into rings of different shapes and sizes according to different openings; the shielding ring 1 is integrally stamped from a 2mm aluminum plate, and the fixing plate 2 is a 2mm thick aluminum fixing plate, which is welded on the upper and lower sides of the shielding ring 1. Mounting holes 20 are provided on the fixing plate 2 .
[0037] see Figure 5 and Image 6 As shown, the installation structure of the shielding ring 1 is introduced in detail by taking th...
