Problems solved by technology
This fixing method has high requirements on the drilling process, and it is easy to drill and crack the electric heating plate and scrap the whole plate. Therefore, the current fixing method has a high scrap rate and high production cost; The plate fell off and the electric heating plate could not be energized for electrothermal conversion
In addition, conventionally, on a microcrystalline / ceramic board with a thickness of 5MM, a hole diameter of 1MM must be drilled when processing a straight blind hole. Such a large hole requires more silver paste to accommodate it, resulting in waste of materials

Embodiment Construction
[0017] A microcrystalline / ceramic electric heating plate, which includes a microcrystalline / ceramic glass plate 1 and an electric heating film 2 on the glass plate 1 under high-temperature vacuum suction, and then the fixing of the wire 3 on the electric heating plate includes the following steps:
[0018] 1) Mill out two inclined grooves 5 on both sides of the microcrystalline / ceramic electric heating plate with a gold steel knife with an oblique angle, such as figure 2 As shown, the depth of the chute is generally suitable between 1 / 3~1 / 2 of the thickness of the electric heating plate. In this embodiment, the inclination directions of the two chute 5 are opposite;
[0019] 2) Insert the wire 3 folded into an obtuse angle obliquely into the chute 5, such as image 3 As shown, the bend of the wire basically just falls on the 5th corner of the chute;
[0020] 3) Spray or silk-screen the melted mercury paste on the electrothermal film. At this time, the silver paste is hidden ...

The invention discloses a microcrystalline / ceramic electric heating plate. The microcrystalline / ceramic electric heating plate comprises a microcrystalline / ceramic glass plate and an electric heating film, and a method for fixing a lead on the microcrystalline / ceramic electric heating plate comprises the following steps of: firstly, processing two chutes on the microcrystalline / ceramic electric heating plate by using an inclined sharp-angled cutter; secondly, inserting the lead which is bent into a blunt angle into the chutes in an inclined way; and thirdly, spraying or silk-screening a melted mercury slurry on the electric heating film and sintering at a high temperature. The lead is inserted into the chutes in an inclined way and the bending position of the lead is rightly clamped by the chutes, so that the lead sintered and fixed by the mercury slurry does not loosen easily, and the lead is fixed more stably and the reliability of energization of the electric heating plate is ensured; and in addition, the process that the chutes are processed with a milling cutter is simpler than the process that a straight blind hole is drilled with a drill bit, so that the condition that the microcrystalline / ceramic electric heating plate is discarded due to a drilling crackle is avoided; therefore, the microcrystalline / ceramic electric heating plate is high in yield and low in production cost.
Description
【Technical field】 [0001] The invention relates to a microcrystal / ceramic electric heating plate, in particular to a method for fixing wires thereon. 【Background technique】 [0002] With the increasingly widespread application of nano-materials, microcrystalline / ceramic electric heating plates have been more and more widely used in the field of electrothermal conversion. At present, the wires that energize the electric heating plate are fixed in this way: First, drill two direct blind holes on the electric heating plate. Then insert the wire vertically and then inject molten mercury paste into the blind hole, and finally take it to high temperature sintering to fix the wire to the electric heating plate. This fixing method has high requirements on the drilling process, and it is easy to drill and crack the electric heating plate and scrap the whole plate. Therefore, the current fixing method has a high scrap rate and high production cost; The plate falls off and the electric...
