NOVELTY - The utility model claims a graphene insulating film structure, comprising graphene heating layer, graphene heating layer is provided with fastener, graphene heating layer far away from one end of the clamping piece is provided with a clamping groove, the clamping piece comprises the round shell sleeve, the round shell sleeve is provided with a connecting end; the connecting end is electrically connected with a connecting wire, the clamping groove is provided with a connecting column. The utility model two adjacent insulating film through one end of the fastener is inserted into the clamping groove to make the two adjacent insulating film connected end of the anastomosis, and the adjacent graphene in the two insulating film heating layer through the connecting lead is electrically connected, through the connecting way, it only needs to heat preservation film starting end is connected with the power supply, namely, it can realize all of the graphene heating layer is electrified, so as to achieve a plurality of graphene insulating film structure are spliced together, which greatly simplifies the wiring structure of the insulating film.
