▎ 摘　　要

NOVELTY - Junction box comprises a box body. The box body is set with wire position. The box body and tube is filled with a flame extinguishing material. The flameextinguishing material comprises substrate, graphene and expandable graphite. The graphene and expandable graphite is uniformly distributed on the base material. The mass of the graphite alkene is 0.000005-10 wt.% substrate. The quality of the expanded graphite is 30-200 wt.% of the substrate. USE - Used as junction box. DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of the junction box.
