The utility model discloses a resistance sorting device of a
ceramic heating sheet, which comprises a test seat for placing the
ceramic heating sheet and a plurality of conductive pieces capable of elastically stretching, the test seat is provided with a plurality of placing grooves, and the groove bottoms of the placing grooves are provided with the conductive pieces. The elastic telescopic ends, facing the groove openings of the placing grooves, of the conductive pieces are used for abutting against the electrodes, facing the groove bottoms of the placing grooves, of the corresponding
ceramic heating pieces and forming electric connection arrangement, the multiple conductive pieces are electrically connected with one another and form an electric connection common end, and the electric connection common end is used for being electrically connected with the first wiring end of the resistance testing unit. The
electrode, facing the notch of the corresponding placing groove, of each ceramic heating sheet is electrically connected with the second wiring end of the resistance testing unit, so that the resistance of each ceramic heating sheet can be quickly tested and sorted, and excessive pressure can be prevented from being applied to the positive
electrode and the negative
electrode of the ceramic heating sheet during resistance testing; therefore, the
resistance test accuracy is ensured, and the
resistance test efficiency is improved.
