The invention relates to a hub/blade wire connecting bracket of an aerogenerator. An upright post is perpendicularly fixed in the center of a manhole cover plate in a blade, and a wire connected to a hub wiring board is wound around the upright post and then is connected to a fan blade wiring board. The wire wound on the upright post is fixed by a strapping tape; and the end of the upright post and the wire are fixed together through a heat shrinkable sleeve, and the hub wiring board and the wire are fixed together through another heat shrinkable sleeve. The invention has the advantages of reasonable design and simple structure. Since the lightning protection wire is relatively fixed by the bracket, the invention effectively solves the problem of wire deformation when the wire rotates along with the blades, overcomes the defects of lightning protection wire rupture and frequent maintenance, prolongs the repair cycle and enhances the production efficiency.
