The invention provides a thin type high-temperature-resistant thermal protection connecting structure, and belongs to the technical field of aircraft thermal protection, the thin type high-temperature-resistant thermal protection connecting structure comprises a thin type high-temperature-resistant thermal protection structure, an embedded circular truncated cone, a plug, a limiting sleeve, a fastener and an aircraft supporting structure, and a wedge-shaped nest is formed in the mounting fastening point position where the thin type high-temperature-resistant thermal protection structure is connected with the aircraft supporting structure; the shape and the outer contour size of the embedded circular truncated cone are matched with those of the wedge-shaped nests, the embedded circular truncated cone is embedded into the wedge-shaped nests in the surface of the thin high-temperature-resistant thermal protection structure, and the limiting sleeve is arranged in the embedded circular truncated cone and at least partially covers the embedded circular truncated cone and an inner hole of the thin high-temperature-resistant thermal protection structure in the length direction of the limiting sleeve. The fastening piece is arranged in the limiting sleeve of the embedded circular truncated cone, the fastening piece penetrates through the thin high-temperature-resistant thermal protection structure and the aircraft supporting structure so as to connect the thin high-temperature-resistant thermal protection structure with the aircraft supporting structure, and the plug is arranged in the embedded circular truncated cone and located outside the head of the fastening piece so as to prevent heat radiation from being conducted to the head of the fastening piece.
