Technical Field

Background
The electrothermal film heating system is a linear heating system represented by a heating cable, and is different from a point heating system represented by a traditional air conditioner, a radiator and the like. When the electrothermal film heating system works, heat is sent into the space in a radiation mode through heating of the electrothermal film, and the comprehensive effect and the comfort degree of the electrothermal film heating system are superior to those of a traditional heating mode.
The heating part of traditional electric heating film heating system is a semi-transparent insulating film which can generate heat after power on, and the semi-transparent insulating film is composed of components such as specially-made printing ink, bus bar and insulating film which can conduct electricity. Specifically, the semitransparent insulation film is prepared by processing special printing ink and bus bars, hot-pressing and covering the bus bars among the insulation films and the like. And the electric heating film is connected with the bus bar and an external power supply circuit through the metal bayonet lock, so that a power supply required by work is obtained. Therefore, the quality of the electric heating film is determined to a great extent by the connection reliability between the metal bayonet lock and the bus bar.
The traditional metal bayonet lock connecting mode is as follows: the metal clamping pin is clamped at the connecting part corresponding to the bus bar and is clamped by using a clamp, and the metal clamping pin pierces the insulating film to be electrically connected with the bus bar through the pressure when the metal clamping pin is clamped by using the clamp. However, in practical operation, since the insulating film and the bus bar need to be connected through the adhesive layer, when the metal bayonet lock is installed, part of the metal bayonet lock cannot completely penetrate the insulating film and the adhesive layer, and therefore cannot completely contact with the bus bar. The electric heating film cannot obtain reliable electric connection, and the product reject ratio is increased.
Therefore, it is required to develop an electrothermal film to solve the above problems.
