Grounding sheet

The invention provides a grounding piece. The grounding piece comprises a first connecting part and a second connecting part which are fixedly connected with a first side; the planes of the first connecting part and the second connecting part are oppositely arranged; and the first connecting part and the second connecting part are open on a second side so that two kinds of shells can be clamped and fixed on the second side. The grounding piece realizes metal connection grounding between the shells, can replace a grounding wire to indirectly connect the shells, does not need to occupy redundantspace of a traction transformer, is beneficial to miniaturization design of the traction transformer, improves reliability and attractiveness, and simultaneously reduces procedures. 本发明公开了一种接地片，包括于第一侧固定连接的第一连接部和第二连接部，所述第一连接部和所述第二连接部的平面相对设置，所述第一连接部和所述第二连接部于第二侧开口以实现于第二侧供两种外壳卡入固定。上述接地片实现外壳之间的金属连接接地，可代替接地线进行外壳间接地连接，不需要占据牵引变压器多余的空间，有利于牵引变压器小型化设计，提升可靠性，美观性，同时减少工序。
