Claims

1. A voltage transformer, comprising a housing, an iron core, windings, and pins, wherein the iron core is wound with windings, the windings comprising a primary winding and a secondary winding, the input terminals and output terminals of the primary winding and the secondary winding being respectively connected to the pins, characterized in that, It also includes a frame, which is assembled at the open end of the shell. The frame is provided with two support arms extending into the shell to assemble the iron core. A limit block is provided at the end of the support arm away from the frame to fix the iron core. The tubes are L-shaped bent structures. The frame is provided with tube hole for assembling the tubes. The tubes can rotate in the tube hole.

2. The voltage transformer as described in claim 1, characterized in that, The frame is also provided with a base, which is stepped and includes a base, a pin hole seat and a support seat. The pin hole seat is provided with through pin holes, and the support seat restricts the rotation angle of the pins.

3. The voltage transformer as described in claim 1 or 2, characterized in that, The pin can rotate at an angle of 120-240°.

4. The voltage transformer as described in claim 3, characterized in that, The pin can rotate 160°.
