Specific embodiment
As shown in figure 1, this utility model includes transformer body 1, primary winding 2, secondary coil 3；Wherein, primary winding
2 and secondary coil 3 closing be embedded poured with epoxy resin formed transformer body 1 in；The upper end both sides of transformer body 1 set
It is equipped with truncated cone-shaped hole；Truncated cone-shaped hole is bottom near transformer body 1 center side, and opposite side is peristome；Truncated cone-shaped hole is divided
For the left truncated cone-shaped hole that is symmetrical set and right truncated cone-shaped hole 5；Once outlet is set at the bottom centre in left truncated cone-shaped hole 4
Terminal 6, setting once input terminal 7 at the bottom centre in right truncated cone-shaped hole 5；Input terminal 7 and an outlet terminal 6
Between pass through epoxy resin poured body dielectric separation one segment distance, so can be further able to ensure insulation safety performance.
The lower section of input terminal 7 and an outlet terminal 6 opens up fluted 8 respectively, is provided with metal even in groove 8
Narrow bars 9；Primary winding 2 passes through secondary coil 3, and primary winding 2 passes through metallic contact strips 9 and an input terminal 7 or respectively
Secondary outlet terminal 6 is connected；The outer end screw 10 of input terminal 7 is passed through cable accessory and is connected with bus closing, such energy
