Abstract
A jointed circuit board used for a Hall electric machine relates to a jointed circuit board. The circuit board of the existing air conditioning electric machine is of a square board with fillets, the middle materials are removed in use, the utilization ratio of the jointed board is low, and the jointed board is easy to deform during wave soldering process. The jointed circuit board comprises a plurality of jointed circuit boards and is characterized in that each circuit board is formed by encircling the inner side edge and the outer side edge of a shape like a right bracket, a first circular arc is arranged at the bending position of the inner side edge, a second circular arc is arranged at the bending position of the outer side edge, the outer side edge of one circuit board is adjacent with the inner side edge of another circuit board, and a plurality of postage stamp holes are arranged at the adjacent position. The outer side edge of one circuit board is adjacent with the inner side edge of another circuit board, so that the occurrence of useless holes in the middle can be avoided, the materials are saved, the material utilization ratio of the jointed circuit board is improved, and the production cost is lowered.
