    • The electrical resistor of the present invention comprises a flat metal plate having a thickness from 8 mils to 50 mils. A pair of electrical leads are operatively attached to the ends of the metal plate, and the side edges of the metal plate are provided with a plurality of notches extending inwardly in spaced apart relation to one another, with slots of one of the sides of the plate being staggered with respect to the slots of the other side of the plate. Each of the slots extend completely through the thickness of the plate and are formed by a laser beam cut which anneals the metal of the plate and imparts stability to the electrical characteristics of the metal plate. Once formed, the metal plate may be bent into different shapes to achieve the desired geometric configuration. Furthermore, the plate can be imbedded in molded material so as to provide a protective covering for the plate.
    • 本发明的电阻器包括厚度为8密耳至50密耳的扁平金属板。 一对电引线可操作地附接到金属板的端部,并且金属板的侧边缘设置有多个彼此间隔开地向内延伸的凹口,其中一个侧面的槽 板相对于板的另一侧的槽交错。 每个槽完全延伸穿过板的厚度,并且通过激光束切割形成,其切断板的金属并赋予金属板的电气特性的稳定性。 一旦形成,金属板可以弯曲成不同的形状以实现所需的几何构型。 此外,板可以嵌入模制材料中,以便为板提供保护性覆盖物。
