It carries out, for example, soldering company is carried out after tin plating on the metal (brass) of contact pin 300, due to having larger sky at manomelia 302
Between, it is not limited or is interfered by other parts, therefore be easy to implement automation leaching soldering operation.
As shown in Figure 19 to Figure 21, then coil winding and stator casing 700 and electromagnetism pole plate 800 are assembled,
Stator module 500 is obtained, lower coil winding and stator casing 700 and electromagnetism pole plate 800 are assembled, obtains lower stator module
600, upper stator module 500 and lower stator module 600 are superimposed and constitute stator module 900, you can carries out electromagnetic coil
The assembling process such as 1000 subsequent embeddings.
It should be noted that during being superimposed upper stator module 500 with lower stator module 600, by two skeletons
Two flange-like portion 20 equipped with maintaining part 30 are oppositely arranged in 100, and the protruding portion 31 of a skeleton 100 is plugged on another skeleton
In 100 lack part 32, the protruding portion 31 of another skeleton 100 is plugged in the lack part 32 of a skeleton 100, two skeletons
100 multiple protruding portion 31 can arrange in alignment, and multiple manomelias 302 are parallel to each other and are generally aligned in the same plane, Duo Gechang
Limb 301 intersects successively to be staggered and parallel to each other.
To sum up, the assembly method of electromagnetic coil according to the ... of the embodiment of the present invention, coiling and welding can be improved
The degree of automation has many advantages, such as production efficiency height, and manufacturing cost is relatively low, additionally it is possible to improve the convenience and just of winding operation
The electromagnetic coil 1000 that quality is high, reliability is good and insulating properties is high can be prepared in true rate.
