DETAILED DESCRIPTION OF THE INVENTION
As shown in the figures, a surface of an electric heating film carrier 1 is coated with an electric heating film, the electric heating film carrier may be made of various dielectric materials such as glass, ceramics, enamel, mica, quartz, and microcrystalline glass, two sides of the electric heating film carrier are coated with layered electrodes 2 and 3, and the layered electrodes 2 and 3 are connected in series to the electric heating film.
The method according to the present invention is as follows. First, a groove is opened in the middle of the layered electrodes 2 and 3 on the electric heating film carrier, and the groove is preferably an annular groove 4, or may also be a V-shaped groove or a square groove. Then, one end of a connecting wire 5 is placed in the annular groove 4, and the connecting wire 5 according to the present invention is preferably a pure silver wire. Afterwards, a conductive adhesive 6 is poured into the annular groove 4 until the annular groove 4 is full, and the conductive adhesive is preferably a silver paste. Finally, the electric heating film carrier is heated around the annular groove 4, so that the electric heating film carrier is just melted and the end of the connecting wire 5 and the conductive adhesive 6 are merged into a whole; and the electric heating film carrier is cooled, and the conductive adhesive is solidified. The connection between the electric heating film carrier and the connecting wire achieved by the foregoing method is very firm, and the reliability is greatly improved.
The protection scope of the present invention is not limited to the foregoing embodiment. As long as a method includes: placing one end of the connecting wire in a groove of the electric heating film carrier, then pouring the conductive adhesive into the groove, afterwards merging the end of the connecting wire and the electric heating film carrier and the conductive adhesive into a whole by heating, and finally performing cooling and solidification, the method falls within the protection scope of the present invention.
