230 cavity shape is identical.
It should be noted that the shape of the first convex block 220 and the second convex block 260 have it is a variety of, for example, circular, T-shaped or terraced
Shape.In the present embodiment, as shown in figure 3, the shape of the first convex block 220 and the second convex block 260 is trapezoidal.It is corresponding, first
The cavity shape of groove 250 matches with the first convex block 220, cavity shape and 260 phase of the second convex block of the second groove 230
Match somebody with somebody.
It should be noted that because 300 domestic demand of centre bore of main framing center pillar 130 is inserted into magnetic core, therefore, the first curved portion
210 or the length of the second positioning pin 270 in curved portion 240 be not more than the thickness of column of main framing center pillar 130.That is, positioning is worked as
When pin 270 is placed in location hole 140, the post jamb that positioning pin 270 is not passed through main framing 100 is put in centre bore 300, can make magnetic
Core is smoothly assembled in the centre bore 300 of main framing center pillar 130.
In order to make the structure after the first curved portion 210 and the combination of the second curved portion 240 more stablize, skeleton further includes glue
Band, adhesive tape ring is around the first arc center pillar 213 and the lateral wall of the second arc center pillar 243.210 He of the first curved portion can so be made
Second curved portion 240 forms an entirety.
In addition, there is first for conducting wire as described in Figure 7, between the first curved baffle 211 and the 3rd curved baffle 241
Gap 280；There is the second gap 281 for conducting wire between second curved baffle 212 and the 4th curved baffle 242.Pass through
One gap 280 or the second gap 281, can make the coiling on skeleton pass through 210 baffle of the first curved portion of movable skeleton 200
Or 240 baffle of the second curved portion.
