Abstract
A dynamic braking resistor as shown and claimed in U.S. Pat. No. 2,680,178 in which the insulator blocks (226) in this new disclosure are formed of a hot-molded organic compound instead of steatite or asbestos. This allows the insulator blocks to be securely mounted to the frame (210, 212), and allows the elimination of the springs, spring cups and pressure plate. In addition, the extra insulative mica sheet required by the above patent is eliminated without loss of protection from short circuits. However, in order to protect the insulator blocks from the heat generated by the resistor ribbons (218, 220), the support clips (232) are made longer to allow more expansion of the ribbons and to hold the ribbons further away from the insulator blocks. In an alternative embodiment, three resistor ribbons (234, 236, 238) are employed, and each support clip (240) supports one reflex bend of all three ribbons.
