The invention relates to a buckle connection structure of an injection
package stator and PCBA board. The buckle connection structure comprises the injection
package stator and the PCBA board located at the bottom of the injection
package stator, the injection package stator comprises an insulation center frame and a plurality of
silicon steel sheets located in the insulation center frame, the insulation center frame is provided with a center sleeve and
welding columns located outside the center sleeve at intervals, the bottom of the center sleeve is provided with buckles protruding towards the bottom of the center sleeve, the PCBA board is provided with a first center hole corresponding to the center sleeve and
welding holes welded and fixed corresponding to the
welding columns, the first center hole is provided with a plurality of first notches corresponding to the buckles, the inner walls of the first notches are matched with the outer walls or the outer side walls of the buckles in shape, the insulation center support of the injection package stator is stably combined with the
silicon steel sheets, the combination force of the injection package stator and the PCBA board is fixed through the welding points, meanwhile, the combination of the buckles and the PCBA board is added, the combination force is further enhanced, the
falling risk is avoided, the stability of the fan injection package stator and PCBA board combination structure is improved, and the service life of the fan injection package stator and PCBA board combination structure is prolonged.
