The invention provides a mutual inductor clamping tray. The clamping tray is used for clamping a mutual inductor and conveying materials. The clamping tray comprises a supporting frame base which is matched with a production line and a tray bottom plate which is installed on the upper surface of the supporting frame base. The clamping tray is characterized in that a plurality of mutual inductor clamping mechanisms are distributed on the tray bottom plate. Mutual inductors are clamped on the clamping tray through the mutual inductor clamping mechanisms, a plurality of manual disassembly/assembly operations are not required in all processes of the whole production line, the mutual inductors can be clamped and conveyed on the whole conveying line through the clamping tray, the conveying working efficiency and the automatic degree of mutual inductors are improved, and the production efficiency of the whole mutual inductor production system is guaranteed.
