Buckle connection structure of injection package stator and PCBA board

Abstract

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.

Description

technical field [0001] The invention relates to a buckle connection structure between a packaged stator and a PCBA board, and belongs to the technical field of fan motor structures. Background technique [0002] The fan is an electric-driven inner counterweight fan blade that turns into natural wind to accelerate air flow, heat dissipation and cooling. It is widely used in electronic devices, cooling devices, household environments, automobiles and other fields. The control circuit of the PCBA board controls the coil of the package stator. After conduction to generate internal excitation, the rotor blade with the coil located outside the packaged stator rotates around the axis, and the packaged stator and PCBA board are combined into a fan motor assembly, which is conducive to rapid assembly, compact and reasonable layout structure Lines, and reliably drive fan blades to rotate on supports such as frames. The shot-wrapped stator is mainly composed of an insulating center fr...

Problems solved by technology

The shot-wrapped stator is mainly composed of an insulating center frame and a number of silicon steel sheets located in the insulating center frame. The insulating center frame is wound with a number of stator coil groups corresponding to the center interval. The shot-wrapped stator and the PCBA board at the bottom are combined by welding. The shot-wrapped stator and The bonding force of the PCBA board is only fixed by the soldering point, which is easy to cause falling off
