The existing power cord and the heating film are connected in a direct manner, and then the heating film and the connection are coated again. Since the working environment of the refrigerator is relatively humid, water droplets often condense on the surface of the heating film. In this way, the poor sealing effect may cause the connection position between the heating film and the power cord to become damp and rusty.
[0003] Therefore, it is necessary to provide a new waterproof sealing structure combination of the heating film and the wiring harness connection position to solve the above technical problems. Utility Model Content

[0006] Plastic frame;
[0007] Double-sided adhesive tape, which is arranged at the bottom of the plastic adhesive frame;
[0008] A heat shrink tube, the heat shrink tube is arranged on the top of the plastic frame;
[0009] Sealant, the sealant is arranged on the outer side of the heat shrink tube.
[0010] Preferably, the thickness of the double-sided tape is 0.5-1.5 mm, and the double-sided tape is VHB double-sided tape.
[0011] Preferably, the heat shrinkable tube is a heat shrinkable tube with hot melt adhesive on the inner wall.
[0012] Preferably, the sealant is a two-component epoxy resin sealant.
[0013] Compared with the related art, the novel waterproof sealing structure combination of the heating film and the wiring harness connection position provided by the utility model has the following beneficial effects:
[0014] The utility model provides a novel waterproof sealing structure combination of the connection position of the heating film and the wiring harness, which cooperates with each other through structures such as a plastic rubber frame, sealant, a heat shrink tube and a double-sided tape. When in use, the connection position between the power cord and the heating film is sealed by the plastic rubber frame and the double-sided tape, which can prevent external moisture from entering the inner side of the plastic rubber frame and prevent rust at the connection between the power cord and the heating film.
