The patent abstract shows that the present disclosure relates to the field of electronic device technology, in particular to a plug, connector, and electronic device. The plug provided in this disclosure includes a wire harness, an internal mold bracket, and a mesh tail; The inner mold bracket is arranged around the wire harness; The net tail covers the inner mold bracket and is connected to the wire harness; Among them, the hardness of the internal mold support is greater than the hardness of the mesh tail. This disclosure involves setting an internal mold support bracket inside the tail of the mesh, and ensuring that the hardness of the internal mold support bracket is greater than that of the tail of the mesh. This enables the internal mold support bracket to support the tail of the mesh, enhance the strength of the tail, improve the independent forming ability of the tail of the mesh, and facilitate the assembly of the tail of the mesh.
