Accompanying drawing explanation
Fig. 1 is the structural representation tapping attachment structure in background technology；
Fig. 2 is the structural representation of tap attachment structure of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.A kind of dry type of the present utility model becomes
The specific embodiment of depressor, as in figure 2 it is shown, include coil, coil is provided with coil tap lead, dry-type transformer also include with
The tap attachment structure that coil tap lead is conductively connected, tap attachment structure includes copper nut and is arranged at copper nut and coil
Being flexible coupling between tap lead, be flexible coupling 3 one end have for weld with coil tap lead 2 be connected be welded to connect
Face, be flexible coupling 3 the other end weld with nut 1 be connected, the face of being welded to connect is positioned at the side deviating from copper nut being flexible coupling.Soft company
Connect 3 to be formed along the thickness direction stacked combination of copper sheet 4 by 5 copper sheets 4.
In process of production, by be flexible coupling 3 one end weld connected with coil tap lead 2, by the other end of 3 that is flexible coupling
Weld with one end of copper nut 1 be connected, then the other end of copper nut 1 is put into casting mold, due to be flexible coupling 3 spy
