Referring to fig. 1-3, a preferred embodiment of the present invention is provided.
The anti-noise reactor iron core comprises a fastening frame 100, a wedge-shaped clamping block 130 and a baffle 120, wherein the fastening frame 100 is rectangular, a rectangular through hole is formed in the fastening frame 100, a fracture surface 110 is formed in the fastening frame 100, a silicon steel sheet 200 in the reactor iron core is inserted into the through hole to be positioned towards the fracture surface 110, the surface facing the silicon steel sheet 200 is parallel to the fracture surface 110, the fracture surface 110 is provided with a vertical fracture 111, the vertical direction is shown as the figure, the fracture 111 divides the fracture surface 110 into two completely independent parts, and a transverse slot 112 of the vertical fracture 111 is formed at the position close to the edge of the fracture surface 110.
The wedge-shaped clamping block 130 is in a triangular prism shape, when the silicon steel sheet 200 is inserted, the wedge-shaped clamping block 130 is inserted into the gap between the fracture surface 110 and the silicon steel sheet 200, and the deeper the wedge-shaped clamping block 130 is inserted, the tighter the silicon steel sheet 200 is clamped. When the installation of the wedge-shaped clamping block 130 is completed, all the wedge-shaped clamping blocks 130 extend into the gap between the fracture surface 110 and the silicon steel sheet 200, at this time, the wedge-shaped clamping block 130 has a tendency to be pushed out of the gap, so that good fixing of the wedge-shaped clamping block 130 is achieved.
According to the reactor iron core provided by the embodiment, the silicon steel sheets 200 are fastened by using the fastening frame 100, after a certain number of silicon steel sheets 200 are inserted into the fastening frame 100, the silicon steel sheets 200 are tightly pressed by inserting the wedge-shaped clamping blocks 130, the tightness between the silicon steel sheets 200 can be greatly improved by adding the wedge-shaped clamping blocks 130, so that the noise in use is well reduced, and meanwhile, the precision requirement of the fastening frame 100 is greatly reduced by the wedge-shaped clamping blocks 130.
In this embodiment, the two transverse slits 112 are included, the two transverse slits 112 are respectively located at two sides of the breaking slit 111, the transverse slits 112 do not intersect with the breaking slit 111, and the two baffle plates 120 are inserted in the transverse slits 112 in a one-to-one correspondence manner, the two baffle plates 120 have a structure that makes the clamping position of the wedge-shaped clamping block 130 more firm, and the transverse slits 112 do not intersect with the breaking slit 111 in order to increase the deformation of the material at the position of the transverse slits 112 after being subjected to low pressure.
In particular, in other embodiments, there may be only one transverse seam 112, and the transverse seam 112 intersects the break seam 111 and is symmetrical about the break seam 111, so that the structure may be better processed and cut out by only using a cutting machine.

In order to facilitate disassembly and maintenance, in the present embodiment, the baffle 120 is inserted into the transverse slit 112, and then the transverse slit 112 is extended from the outside to form a disassembly portion 121. Thus, the baffle 120 can be pulled out by the detaching portion 121, and the wedge-shaped clamp 130 can be taken out for detachment.
The present patent also provides another anti-noise reactor core, which also includes the fastening frame 100, the transverse seam 112 and the breaking seam 111, however, here, the transverse seam 112 intersects with the breaking seam 111, as shown in fig. 3, the structure of the insert board is omitted in this embodiment, since the transverse seam 112 intersects with the breaking seam 111, the cantilever plate 113 as shown in the figure is separated, after the positioning of the wedge-shaped clamping block 130 is completed, the cantilever plate 113 can also abut against the wedge-shaped clamping block 130 after being pressed and bent towards the direction of the silicon steel sheet 200, so that the structure is simpler, and is easier to operate, so that the cost is further reduced.
