METHOD FOR ASSEMBLING LOAD SENSOR

Japanese Patent JPS63168524

A

PURPOSE:To uniformize a resistance characteristic, at the time of the assembling of a load sensor consisting of a power plate to be distorted by external force and pressure-sensitive conductive rubber converting the distortion quantity of said plate to resistance change, by pressing the conductive rubber while monitoring the resistance thereof to fix the same at a predetermined position. CONSTITUTION:An electrode 1 for pressure-sensitive conductive rubber, the wiring 2 of a circuit for detecting pressing force and an adhesive metal surface 3 for soldering a spacer part to an epoxy resin substrate 5 are formed to the surface of the substrate 5 by photoengraving, and a spacer 7 composed of a stainless steel plate coated with a predetermined amount of a solder cream 6 on both front and back surface thereof, pressure-sensitive conductive rubber 8 and a rotary element 9 for detecting resistance are provided on the metal surface surface 3. A printed wiring board 10 is provided on the spacer 7 and the conductive rubber 8 to form a combination body 11' and a heating apparatus 12 composed of a halogen lamp is mounted so as to correspond to the spacer 7 to perform temporary fixing at first under heating. Thereafter, the solder part is plastically deformed by pressing and final fixing is performed when the resistance measured by a resistance measuring apparatus 14 reaches a predetermined value.
