[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.
[0022] Embodiment 1:
[0023] The utility model provides a silicon steel sheet for transformer, please refer to Figure 1-2 , comprising a silicon steel sheet body 1, the front and back sides of the silicon steel sheet body 1 are provided with a plug-in structure;
[0024] The plug-in structure includes slots and plug-in blocks located on the front and back of the silicon steel sheet body 1. The slots and the plug-in blocks can be connected by interference fit, so that there will be no relative movement between the silicon steel sheet bodies 1, thereby ensuring that the silicon steel sheets are stacked tightly.
[0025] The slot is set as a first groove 11, and the insert block is set as a first protrusion 12. The first groove 11 and the first protrusion 12 are symmetrically located on the front and back sides of the silicon steel sheet body 1, and can be plugged in with interference fit.
[0026] In specific use, when the silicon steel sheet bodies 1 are stacked, the first protrusions 12 on the silicon steel sheet bodies 1 are inserted into the first grooves 11 of adjacent silicon steel sheet bodies 1, thereby achieving tight strength between the silicon steel sheets and avoiding relative movement between the silicon steel sheet bodies 1.
[0027] Embodiment 2:
[0028] See attached Figure 3-4 , which is different from Example 1, is that the slot is set as a second groove 13, and the plug block is set as a second protrusion 14; the second groove 13 and the second protrusion 14 are symmetrically located on the front and back sides of the silicon steel sheet body 1, and can be plugged in with interference fit.
[0029] Small grooves 131 are arranged at equal intervals on the inner wall of the second groove 13 , and small protrusions 141 are integrally formed on the outer wall of the second protrusion 14 . Each small protrusion 141 can be inserted into the small grooves 131 , respectively.
[0030] During specific use, when the silicon steel sheet bodies 1 are stacked, the second protrusion 14 on the silicon steel sheet body 1 is inserted into the second groove 13 of the adjacent silicon steel sheet body 1, and the small protrusion 141 is inserted into the small groove 131, thereby achieving tight strength between the silicon steel sheets and avoiding relative movement between the silicon steel sheet bodies 1.
[0031] Embodiment 3:
[0032] See attached Figure 5-6 , which is different from Example 1, is that the slot is set as a strip slot 15, the insert block is set as a strip block 16, and the strip slot 15 and the strip block 16 are both equal to the width of the silicon steel sheet body 1; at this time, the silicon steel sheet bodies 1 cannot be stacked together one by one, and the silicon steel sheet body 1 can be slowly slid from the left and right ends of another silicon steel sheet body 1 into another silicon steel sheet body 1, which makes it easier to perform the stacking operation.
[0033] In specific use, when the silicon steel sheet bodies 1 are stacked, the strip blocks 16 on the silicon steel sheet bodies 1 are inserted into the strip grooves 15 of adjacent silicon steel sheet bodies 1, thereby achieving tight strength between the silicon steel sheets and avoiding relative movement between the silicon steel sheet bodies 1.
