Summary of the invention

The utility model purpose is to provide a kind of lead tapping device of thick film heating element, broad application temperature range, and the life-span is long; Use stainless steel-like thick film heating element as heating matrix, add a cover lead tapping device on its silver electrode, making goes between is not easy to come off the thick film heating element, and then can better use the high thick film heating element of heating temp.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of Lead-out Device Of Thick Film Heater, include lead, the locating module inside of one shaped as frame is formed with the inserting-plate hole that runs through it, be provided with two bar shaped reference columns that are attached to both sides, locating module bottom surface under the inserting-plate hole in the locating module frame, locating module frame inner bottom surface middle part is provided with the convex reference column, form location notch between bar shaped reference column and the convex reference column, be provided with insertable spring leaf in the location notch in the locating module, the spring leaf end connects lead, and lead passes location notch and is drawn out to outside the locating module.

The utility model uses stainless steel-like thick film heating element as heating matrix, on its silver electrode, add a cover lead tapping device, device includes spring leaf, lead, locating module, on corrosion resistant plate, carry out earlier the thick film pyrotoxin, and print silver electrode, then two spring leafs that weld lead are placed on respectively on the two limit electrodes, and insert in the location notch of locating module, then the heating sheet is inserted in the inserting-plate hole of locating module into, whole thick film heating element and ejector thereof have just formed.The utility model solves the problem that serviceability temperature is low and the life-span is short that scolding tin caused on the thick film heating element.
