Abstract
The invention discloses a connection structure of a motor stator and a stator circuit board. A plastic inner ring is fixed to the inner circumferential side of a stator iron core; the stator circuit board is mounted at the end part of the plastic inner ring; and a cold welding connection structure is arranged between the end part of the plastic inner ring and the stator circuit board. At least three protrusions are uniformly arranged on the end part of the plastic inner ring, and the protrusions cover the edge of the stator circuit board after being coldly welded. The end part of the plastic inner ring is welded with the stator circuit board by cold molding, so that the connection structure of the motor stator and the stator circuit board has better corrosion resistance and rust resistance and high mechanical strength.
Description
Technical field
The present invention relates to motor stator and stator track board connecting structure.
Background technology
Stator comprises stator core, stator core inner periphery fixed plastics inner ring, and the stator track plate is installed in plastics inner ring end.The stator track plate passes through screw on the plastics inner ring in the prior art, but screw gets rusty easily, and causes mechanical strength to reduce.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of motor stator and stator track board connecting structure, and antiseptic and rustproof performance is good, and mechanical strength is high.
For solving the problems of the technologies described above; The present invention adopts following technical scheme: motor stator and stator track board connecting structure; Stator core inner circumferential side fixed plastics inner ring; The stator track plate is installed in plastics inner ring end, it is characterized in that: be connected for cold welding between said plastics inner ring end and stator track plate.
Preferably, said plastics inner ring end evenly is provided with at least three juts, is down L shaped coating stator track panel edges behind the said jut cold welding.
Preferably, said plastics inner ring end evenly is provided with plurality of gaps, and said jut is located on the boss between the gap.
Through the cold moulding welding, antiseptic and rustproof performance is better between plastics inner ring end of the present invention and stator track plate, and mechanical strength is high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is the plastics inner ring and the stator track board connecting structure sketch map of motor stator;
Fig. 2 is a wiring board outer face structural representation;
Fig. 3 is a structural representation behind the jut cold welding.
Embodiment
Extremely shown in Figure 3 like Fig. 1; Embodiment for motor stator of the present invention and stator track board connecting structure; Stator core 1 inner circumferential side fixed plastics inner ring 2, plastics inner ring end are installed stator track plate 6, are connected for cold welding between said plastics inner ring end and stator track plate.Said plastics inner ring end outer rim evenly is provided with at least three juts 5, is down L shaped coating stator track panel edges behind the said jut cold welding.Said plastics inner ring end evenly is provided with plurality of gaps 4, and said jut is located on the boss 3 between the gap.
