ABSTRACT:
A resistor grid assembly has a continuous resistor weave with a plurality of generally parallel, plate-like electrical elements. U-shaped bends join two adjacent elements at adjacent ends. The U-shaped bends are located in a bottom group and a top group. There is a top electrical insulating member adjacent the U-shaped bends in the top group and spaced from the U-shaped bends. There is a bottom electrical insulating member adjacent the U-shaped bends in the bottom group. Stop U-shaped pins having a pair of legs with a pair of shoulders are supported by the bottom electrical insulating member. The legs of each stop U-shaped pin extends into a pair of holes in the bottom group of U-shaped pins and rest upon the shoulders which are spaced from the insulator. Wire U-shaped pins are supported by the top electrical insulating member. The wire U-shaped pins have legs inserted into holes in the U-shaped bends in the top group. The U-shaped bends in the top group are spaced from the top insulator. When the resistor elements expand due to heat, the U-shaped bends in the top group move on the legs of the wire U-shaped pin toward the top insulating member. Expansion is controlled in a direction toward the top insulating member and the resistor U-shaped bend slides on the wire U-shaped pin.
