Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a stator core for a transformer. Background Art

[0002] The transformer core is an important part of the transformer. It is made of silicon steel sheets or other high permeability materials. The transformer core needs to be wound with a coil. Its main function is to conduct and concentrate magnetic flux, reduce magnetic resistance, reduce magnetic flux loss, and improve the efficiency of the transformer. The transformer core is one of the most important parts of the transformer and directly affects the performance and efficiency of the transformer. Reasonable design and selection of the core can improve the working efficiency of the transformer, reduce losses, and ensure the reliability and stability of the transformer.

[0003] Traditional transformer cores are usually fixed with bolts and nuts that penetrate the entire core group. This assembly method is not convenient for quick assembly or quick disassembly, and specific tools are required for disassembly or assembly, which makes it inconvenient to use.

[0004] Therefore, those skilled in the art provide a stator core for a transformer to solve the problems raised in the above background technology. Utility Model Content

[0005] The utility model aims to solve the shortcomings existing in the prior art and proposes a stator core for a transformer. When assembling the core, a plurality of middle iron core sheets are inserted into four through-columns, and then the front iron core sheets are inserted to realize assembly. The oblique clamping blocks on the front iron core sheets are compressed by the through-columns and retracted into the inside of the fixer. When the limiting hole reaches the specified position, the spring drives the oblique clamping blocks to automatically pop out to realize fixation. When disassembly is required, the dial block can be moved to retract the oblique clamping blocks to cancel the limiting position, and disassembly can be carried out, thereby realizing easy assembly and disassembly, saving assembly and disassembly time, and being easy to use.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A stator core for a transformer comprises a front iron core, a rear iron core and a plurality of middle iron cores, wherein the front iron core and the plurality of middle iron cores are each provided with four through holes, the front end surface of the rear iron core is fixedly provided with four through columns, each of the four through columns has a plurality of through holes, the front end surface of the front iron core is evenly fixedly provided with four fixers, the four through columns are each provided with limiting holes on one side close to the fixer, a support spring is each fixedly provided at one end inside the four fixers, an oblique clamping block is each fixedly provided on the outer side of the four support springs, a movable groove is each provided on the front end surface of the four fixers, and a shifting block is each fixedly provided on the front end surface of the four oblique clamping blocks.

[0008] Through the above technical solution, during installation, multiple middle iron chips are put on the through column in sequence, and finally the front iron chip is put on the through column. When the limiting hole reaches the corresponding position of the oblique block, it is automatically locked in to achieve fixation. During disassembly, the limiting of the oblique block can be canceled by moving the shift block, and the fixation can be canceled for disassembly.

[0009] Furthermore, a plurality of limiting columns are evenly and fixedly arranged on opposite sides of the front iron core sheet and the rear iron core sheet;

[0010] Through the above technical solution, the uniform limiting pillars can facilitate the subsequent coil winding and can play a limiting role on the coil, so that the coil gap can be more uniform after winding.

[0011] Furthermore, a pair of mounting blocks are fixedly disposed on opposite sides of the bottom of the front iron core sheet and the rear iron core sheet;

[0012] Through the above technical solution, the mounting block can be in contact with the transformer base, which is convenient for installation and fixation.

[0013] Furthermore, a mounting hole is provided in the middle of each of the four mounting blocks;

[0014] Through the above technical solution, the mounting hole can be easily inserted with bolts or screws for fixing.

[0015] Furthermore, the plurality of limit posts are all made of ceramic material;

[0016] Through the above technical solution, the ceramic limiting column can play an insulating role.

[0017] Furthermore, the four oblique clamping blocks are respectively clamped with the four limiting holes;

[0018] Through the above technical solution, the oblique clamping block is clamped into the limiting hole to achieve clamping and fixing.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model provides a stator core for a transformer. When assembling the core, a plurality of middle iron core sheets are inserted into four through-columns, and then the front iron core sheets are inserted to realize assembly.

When the limit hole reaches the specified position, the spring drives the oblique clamping blocks to automatically pop out to realize fixation. When disassembly is required, the oblique clamping blocks can be retracted to cancel the limit by toggling the toggle blocks, and then disassembly can be performed, thereby realizing easy assembly and disassembly, saving assembly and disassembly time, and being easy to use.
