The outer walls of the contact parts of the 2 iron cores 1 are sleeved with insulating gaskets 7, and the insulating gaskets 7 are clamped by the 2 insulating sleeves 4. In order to make the iron core contact more tightly and sufficiently, a certain gap is usually left between the opposite surfaces of the two insulating sleeves, but at this time, the joint portion of the iron core 1 is partially exposed, and in order to seal the iron core 1, the exposed iron core needs to be protected by the insulating pad.
