Abstract
Description
Technical Field
[0001] This application relates to the technical field of silicon steel sheets, and specifically to a silicon steel sheet. Background Art
[0002] Silicon steel sheets are an iron-silicon alloy mainly used for making silicon steel sheets of various motors and transformers. It contains 0.5% to 4.5% silicon. The characteristics of this alloy are high magnetic permeability and low magnetic loss. Silicon steel sheets can be divided into two types: hot-rolled and cold-rolled. Among them, cold-rolled silicon steel sheets are widely used in power and electronic equipment due to their excellent magnetic properties and low losses.
[0003] In the manufacture of transformer silicon steel sheets, silicon steel sheets in the shape of "E" and "I" are usually used. The connection of transformer silicon steel sheets generally refers to the physical splicing method of silicon steel sheet materials. When stacking iron cores, insulating paper or film is placed between each layer, then glue is applied, and then they are pressed into a whole by mechanical pressure to form a continuous magnetic path. Silicon steel sheets are usually composed of multiple thin silicon steel sheets, which are coated with insulating paint and stacked to reduce eddy current losses. The connection method of silicon steel sheets is crucial for the performance of transformers because it affects the continuity of magnetic flux and the overall magnetic permeability.
[0004] However, the main existing connection method of silicon steel sheets is to bond multiple silicon steel sheets together with glue. When the bonded silicon steel sheets work at high temperatures, the glue will melt, resulting in the problem that the connection between each silicon steel sheet is no longer firm.
[0005] Therefore, it is necessary to provide a silicon steel sheet to solve the above problems.
[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Utility Model Content

At the four corners of the top of the "E" type plate, extrusion holes located at the bottom of the mating holes are also provided. The diameter of the extrusion holes is larger than that of the mating holes. At the four corners of the bottom of the "E" type plate, deformation rods are fixedly connected.
[0009] Furthermore, the deformable rod is composed of an insertion rod and at least one inwardly inclined locking plate. The deformable rod can be inserted into the fitting hole and the extrusion hole, and the diameter dimension of the deformable rod is adapted to the diameter dimension of the fitting hole.
[0010] Furthermore, the "E"-shaped plate includes two outer arms and one inner arm. Fitting buckles are installed on the inner sides of the two outer arms of the "E"-shaped plate, alignment tracks are installed on the outer sides of the two outer arms of the "E"-shaped plate, and two splicing blocks are fixedly connected to one side of the middle arm of the "E"-shaped plate.
[0011] Furthermore, the "I"-plate structure includes an "I"-shaped plate. Fitting sliders are fixedly connected to both sides of the "I"-shaped plate. Two locking buckles are installed on one side of the "I"-shaped plate. Two positioning holes are provided in the middle of one side of the "I"-shaped plate. The fitting sliders and the alignment tracks cooperate with each other.
[0012] Furthermore, chutes adapted to the size of the fitting sliders are provided on the opposite sides of the two alignment tracks, and the sizes of the two splicing blocks are adapted to the sizes of the positioning slots provided on one side of the "I"-shaped plate.
[0013] Furthermore, when the locking buckle and the fitting buckle are locked and matched, the first side A of the locking buckle in contact with the fitting buckle is arranged in an arc shape, and the second side B of the fitting buckle in contact with the locking buckle is designed as an inclined surface.

Mating holes 15 are opened at the four corners of the top of the "E"-shaped plate 11. The diameter of the extrusion hole 16 is larger than the diameter of the mating hole 15. The main purpose of opening the mating hole 15 is to locate and connect the next "E" plate structure 1. Extrusion holes 16 are also opened at the four corners of the top of the "E"-shaped plate 11 at the bottom of the mating holes 15. Deformation rods 17 are fixedly connected to the four corners of the bottom of the "E"-shaped plate 11.
[0028] The deformation rod 17 is composed of an insertion rod and at least one inwardly inclined locking plate. The deformation rod can be inserted into the mating hole and the extrusion hole. The locking plate is designed as a thin plate and is directly cut by a cutting device. The diameter dimension of the deformation rod 17 is adapted to the diameter dimension of the mating hole 15. The main purpose of the extrusion hole 16 is to cooperate with the deformation rod 17 to lock after it explodes.
[0029] The "E"-shaped plate 11 includes two outer arms and one inner arm. Fitting buckles 12 are installed on the inner sides of the two outer arms of the "E"-shaped plate 11, alignment tracks 13 are installed on the outer sides of the two outer arms of the "E"-shaped plate 11, and two splicing blocks 14 are fixedly connected to one side of the middle arm of the "E"-shaped plate 11.
[0030] The "I"-plate structure 2 includes an "I"-shaped plate 21. Fitting sliders 22 are fixedly connected to both sides of the "I"-shaped plate 21, two locking buckles 23 are installed on one side of the "I"-shaped plate 21, two positioning holes are formed in the middle of one side of the "I"-shaped plate 21, and the fitting sliders 22 and the alignment tracks 13 cooperate with each other.
[0031] Chutes adapted to the sizes of the fitting sliders 22 are formed on the opposite sides of the two alignment tracks 13, and the sizes of the two splicing blocks 14 are adapted to the sizes of the positioning slots formed on one side of the "I"-shaped plate 21.
[0032] When the locking buckle 23 and the fitting buckle 12 are locked and cooperate, the first side A of the locking buckle 23 in contact with the fitting buckle 12 is arranged in an arc shape, and the second side B of the fitting buckle 12 in contact with the locking buckle 23 is designed as an inclined surface.
[0033] The connecting part of the locking buckle 23 and the "I"-shaped plate 21 is designed as a thin plate, and the locking buckle 23 has a resilient property.
[0034] One inner arm in the middle of the "E"-shaped plate 11 is used for winding copper wire.
