本发明叙述一种加热元件,用于真空或惰性气氛高温电阻炉的一种柔性的加热元件。图1是按本发明做成的加热元件之平面图。图2是沿图1的2—2线所取的剖面图。参考图1,本发明的加热元件包含一对彼此分开的汇流排11和13,一个柔性的石墨布电阻元件16(张在汇流排11,13之间)和有弹性的弹簧夹17(用来把石墨布15夹紧在汇流排11,13上)由适当的导体19,21把汇流排11,13连接到电源23。
The present invention relates to a heating element, a flexible heating element for use in a vacuum or inert atmosphere high temperature resistance furnace. Figure 1 is a plan view of a heating element according to the invention. Fig. 2 is a sectional view taken along line 2-2 of Fig. 1. With reference to Figure 1, the heating element of the invention comprises a pair of busbars 11 and 13 spaced apart from each other, a flexible graphite cloth resistive element 16 (shown between the busbars 11, 13) and a resilient spring clip 17 Clamping the graphite cloth 15 on the busbars 11, 13) The busbars 11, 13 are connected to the power supply 23 by appropriate conductors 19, 21.
