Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and particularly relates to a connection structure of a graphene heating film. Background Art

[0002] The flat structure of the graphene heating film results in that its electrical connection must be a flat copper strip, and how to connect the copper strip with an external wire is a difficult problem. The traditional methods are generally carried out in the following two ways:

[0003] The first is that a puncture nail penetrates through the heating film to make the puncture point between the puncture nail and the copper strip contact and conduct electricity. However, the contact area of the puncture nail is small, and poor contact may occur when working with large currents.

[0004] The other is to connect the copper strip electrically by punching holes, inserting round terminal pieces, and fixing with rivets, so as to achieve surface contact between the round terminal piece and the copper strip, and the rivet fixing keeps the contact stable.

[0005] However, in the related art, the connection by the puncture nail or punching holes is inconvenient, and both require penetrating the heating film up and down. At the same time, the aluminum film cannot be completely covered at the live wire, which is easy to generate static electricity or slight leakage. Summary of the Utility Model

The neutral wire and the live wire are arranged on the upper surface of the graphene heating film, and the PET film covers the upper surface and the lower surface of the graphene heating film.

[0009] Preferably, a first aluminum film layer is arranged on the upper surface of the graphene heating film strip, and a second aluminum film layer is arranged on the lower surface of the graphene heating film strip.

[0010] Preferably, the first aluminum film layer covers the neutral wire and the live wire.

[0011] Preferably, the second aluminum film layer covers the neutral wire, and the distance between the second aluminum film layer and the live wire is greater than 3 mm.

The first insulating portion and the second insulating portion are perpendicular to each other, and the first insulating portion and the second insulating portion jointly cover the conductive sheet.

[0013] Preferably, there are two connecting terminals. One connecting terminal is connected to the neutral wire, and the other connecting terminal is connected to the live wire.

[0014] Preferably, one side of the first insulating portion is closely attached to the second aluminum film layer, and the width of the first insulating portion is greater than 3 mm.

[0015] Preferably, in the connecting terminal connected to the live wire, the distance between the conductive sheet and the second aluminum film layer is greater than 3 mm.

[0016] Preferably, a clip is provided on the outer side of the connecting terminal. The clip is used to increase the clamping force of the connecting terminal and make the connection more stable.

[0017] Preferably, a tape layer is provided on the outer side of the clip. The tape layer is used to fix the clip on the connecting terminal and the graphene heating film strip.
