A transformer core fastening device

Abstract

This invention relates to the field of transformer core fixing technology, specifically a transformer core fastening device, including clamps, specifically two clamps. The top of the clamps is bent outward to form a handle edge plate, and the bottom of the clamps is bent outward to form a fixing base plate. The upper and lower sides of the clamps have slots, and the top and bottom of the outer sides of the slots are provided with bolting plates. A first hole is formed on the bolting plates. Sealing plates are fitted into the slots where the two clamps are flush. The end of the sealing plate has a through hole communicating with the first hole for bolting fixation. The spacing between the sealing plates is the same as the total width of the transformer core chip. This invention solves the problem of needing to drill holes in the chip by fixing it in all directions (front, back, left, and right). The combination of clamps and sealing plates prevents displacement of the chip in all directions, achieving the same limiting effect as fixing a drilled hole, reducing chip processing steps and lowering processing costs.

Description

Technical Field

[0001] This invention relates to the field of transformer core fixing technology, specifically a transformer core fastening device. Background Technology

[0002] The ferrules of the transformer core are thin sheets that are fixedly attached to each other. After they are installed in close arrangement, a clamping plate needs to be installed on the outside. Through holes are opened at both ends of the ferrules. The threaded rod passes through the through holes of the clamping plate and out through the through holes of the ferrules. Then, the threaded rod is tightened with a nut to fix it, thereby fixing the transformer core. This design requires drilling holes in each chip, which affects processing efficiency and increases processing costs. Summary of the Invention

[0003] The purpose of this invention is to provide a transformer core fastening device to solve the problem mentioned in the background art that transformer core chips need to be drilled.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A transformer core fastening device includes two clamping plates. The top of each clamping plate is bent outward to form a handle edge plate, and the bottom of the clamping plate is bent outward to form a fixing base plate. The upper and lower sides of each clamping plate have slots. The top and bottom of the outer side of the slots are provided with bolting plates. A first hole is provided on the bolting plates. Sealing plates are fastened at the slots where the two clamping plates are aligned. The end of the sealing plate has a through hole communicating with the first hole for bolting and fixing. The spacing between the sealing plates is the same as the total width of the transformer core.

[0005] As a further description of the above technical solution: The width of the handle edge plate is 2-3cm.

[0006] As a further description of the above technical solution: The width of the fixed base plate is 4-5cm.

[0007] As a further description of the above technical solution: A second hole is made on the fixed base plate.

[0008] As a further description of the above technical solution: The side of the clamp is flush with the side of the sealing plate.

[0009] As a further description of the above technical solution: The width of the sealing plate is the same as the depth of the slot.

[0010] Compared with the prior art, the present invention provides a transformer core fastening device, which has the following beneficial effects: 1. In this invention, by fixing the transformer core chip in the front, back, left and right directions, the problem of needing to open holes in the chip is solved. The combination of clamping plate and sealing plate can prevent the chip from shifting in the front, back, left and right directions, achieving the same limiting effect as fixing the chip when opening holes, reducing chip processing steps and lowering processing costs. 2. In this invention, the design is easy to assemble and disassemble. The bent design of the handle plate and the fixed base plate makes it easy to pick up the clamping plate and also makes it easy to position and fix the clamping plate. Attached Figure Description

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Example: Please see Figure 1 This invention provides a transformer core fastening device, including clamping plates 1, which are two pieces. The top of the clamping plates 1 is bent outward to form a handle edge plate 2, and the bottom of the clamping plates 1 is bent outward to form a fixing base plate 3. The upper and lower sides of the clamping plates 1 are provided with slots 4. The top and bottom of the outer side of the slots 4 are provided with bolting plates 5. The bolting plates 5 are provided with a first hole 6. The two clamping plates 1 are aligned with the slots 4 and a sealing plate 7 is installed. The end of the sealing plate 7 is provided with a through hole that communicates with the first hole 6 and can be bolted and fixed. The spacing between the sealing plates 7 is the same as the total width of the transformer core.

[0015] Specifically, the width of the handle edge plate 2 is 2-3cm for easy operation.

[0016] Specifically, the width of the fixed base plate 3 is 4-5cm, and a second hole 8 is opened on the fixed base plate 3 to reserve space for the use of power tools.

[0017] Specifically, the side of the clamping plate 1 is flush with the side of the sealing plate 7.

[0018] Specifically, the width of the cover plate 7 is the same as the depth of the slot 4, and the dimensions are matched to avoid the cover plate 7 damaging or squeezing the chip.

[0019] Working principle: After the chips of the transformer core are tightly arranged, a clamping plate 1 is placed on the outside of the chip. The two clamping plates 1 clamp the chip tightly. At the second hole 8, a tool and bolts are used to fix the fixing base plate 3 to the frame. Then, the sealing plate 7 is pushed in at the slot 4. The sealing plate 7 is stuck in front and behind the chip. Finally, the bolting plate 5 and the sealing plate 7 are bolted together at the bolting plate 5. In this way, the chip is fixed in front, behind, left and right, and the chip itself no longer needs to be drilled.

[0020] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
