Transformer insulating shell convenient for fly wire winding

The utility model relates to a transformer insulation shell convenient for winding a fly wire, the outer side wall of at least one side of the insulation shell is provided with a first wire clamping through groove for winding the fly wire of a transformer winding, the first wire clamping through groove is detachably provided with a cover plate block, and the fly wire of the transformer winding can be wound along the side wall of the insulation shell and clamped into the first wire clamping through groove. The circuit board is clamped in by the first wire clamping through groove and is further fixed by the cover plate block, so that flying wires are prevented from flying, and the circuit of the circuit board is concise and tidy. 本实用新型涉及一种便于飞线绕行的变压器绝缘外壳，绝缘外壳至少一侧外侧壁设有用于供变压器绕组飞线绕行的第一卡线通槽，第一卡线通槽上可拆卸地设有一盖板块，变压器的绕组飞线可沿绝缘外壳侧壁绕行卡入第一卡线通槽，由第一卡线通槽卡入，再由盖板块进一步固定，避免飞线乱飞，使得电路板的线路简练整洁。
