[0002] In the prior art, reactor winding or foil winding is an important process. When winding or foil winding, terminal blocks need to be installed at the same time. The prior art usually uses glass fiber tape to fix the terminal blocks in three places to prevent the terminal blocks from moving due to the tension during the winding process. This fixing method makes it easy for the tail of the terminal block to shift under the tension of the winding machine, and eventually causes the outgoing terminal block to tilt. This defect in the setting affects the consistency of the three-phase terminal block, and may also cause difficulties when installing the wiring at the client end, affecting the overall quality of the product and the user experience.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In order to solve the problem of stable winding of the foil winding 11 and the terminal block of the inductor assembly in the prior art, the present application provides a reactor winding mold.

[0030] In one possible implementation, see Figure 1 , Figure 2 and Figure 3 , a reactor winding mold, comprising: two mold cores 1, both ends of the two mold cores 1 are assembled through baffles respectively; a left clamping plate 5 and a right clamping plate 2 clamped at both ends of the mold core 1, a starting terminal row 10 and an ending terminal row 4 clamped between the left clamping plate 5 and the right clamping plate 2; two or more positioning pins 6 are arranged on the left clamping plate 5, and a wire outlet groove is arranged on the right clamping plate 2, one end of the starting terminal row 10 and the ending terminal row 4 are respectively installed in the positioning pins 6, and the other end of the starting terminal row 10 is placed in the wire outlet groove of the right baffle 2, and also includes: an ending terminal row fixing plate 3, which is installed on the right clamping plate 2 and supports the ending terminal row 4; the positioning pin 6 includes two claws for clamping the starting terminal row and the ending terminal row; and also includes: a mold shaft 7, which passes through the left clamping plate 5, the left baffle 12, the centers of the two mold cores 1, the right baffle and the center holes of the right clamping plate 2 in sequence, and extends out of the two ends of the mold core.

[0031] In a possible implementation, the process of constructing a reactor winding mold is as follows: first, two mold cores with predetermined shapes and sizes are selected, and the mold cores are firmly connected by two baffles with a certain thickness and rigidity. The baffles can be made of high-strength materials to ensure the stability of the mold during the winding process.

[0032] Next, the left and right clamps are installed on both sides of the two mold cores. The left clamp is preset with two or more positioning pins to fix the starting terminal block and the ending terminal block to ensure their stable position during the winding process. These positioning pins are provided with claw structures to facilitate the quick installation or removal of the terminal block while providing reliable fixation. The right clamp is provided with a wire outlet groove to guide the wound coil out of the mold while reducing friction and damage to the wire.

[0033] In order to further improve the reliability and service life of the mold, the mold shaft is made of high-strength metal material, runs through the entire center of the mold, and extends from both ends. This not only provides the necessary structural support for the mold, but also cooperates with the external rotating tooling to realize the automatic rotation winding of the mold.

[0034] In addition, the mold also includes an end terminal row fixing plate 3, which is installed on the right clamping plate 2 and is specifically used to support and fix the end terminal row 4 to prevent movement or loosening during the winding process.

[0035] Through the precise assembly of the above components, the reactor winding mold not only has excellent structural stability and reliability, but also can effectively improve the winding efficiency and quality of the reactor coil. In practical applications, according to different reactor specifications and winding requirements, the size, shape and specific settings of the mold components can be appropriately adjusted and optimized.

[0036] In a possible implementation manner, the starting terminal row 10 and the ending terminal row 4 are stacked one on top of the other, and an insulating layer is disposed on the surfaces of the starting terminal row 10 and the ending terminal row 4 .

[0037] In the above scheme, a further embodiment involves the specific installation method of the starting terminal row 10 and the ending terminal row 4 and the enhancement of their insulation performance. In this embodiment, the starting terminal row 10 and the ending terminal row 4 are arranged as a structure that can be stacked up and down. This arrangement allows the mold to accommodate more terminal connections in a limited space, thereby improving the connection flexibility and application range of the reactor. In order to ensure the safety and reliability of the reactor during operation, the surface of the starting terminal row 10 and the ending terminal row 4 is covered with a layer of insulating material. This layer of insulating material can be a polymer composite material with excellent electrical insulation performance, heat resistance and mechanical strength. By arranging an insulating layer on the surface of the terminal row, the occurrence of electrical short circuit or insulation damage can be effectively prevented, ensuring the stable operation and long-term reliability of the reactor. In the specific implementation process, the insulating layer of the starting terminal row 10 and the ending terminal row 4 can be formed by spraying, dipping or covering with an insulating film. The selection of suitable insulating materials and processing technology not only affects the insulation effect of the terminal, but also directly affects the production efficiency and maintenance convenience of the mold. Therefore, during the setting and manufacturing stages, the physical and chemical properties of the insulating material, processing costs, and maintenance requirements need to be comprehensively considered to achieve the best overall performance and economic benefits. This embodiment significantly improves the setting flexibility and application safety of the reactor winding mold by stacking the terminal blocks up and down and insulating the surface, providing a solid foundation for the efficient production and reliable use of the reactor.

[0038] In a possible implementation manner, one end of the right clamping plate 2 has warps of different heights, and the starting terminal row 10 and the ending terminal row 4 do not contact each other at the warped portion.

[0039] On this basis, this embodiment introduces a terminal row warping setting to further optimize the functionality and ease of operation of the reactor winding mold. In this embodiment, the starting terminal row 10 and the ending terminal row 4 are set with a slight warping at a position close to one end of the right clamping plate 2, and the warping heights of the two are different to ensure that they do not contact at the warping. The purpose of this warping setting is to facilitate the lead-out and connection of the coil while avoiding the potential short circuit risk caused by physical contact between the terminal rows. The warped terminal row can not only simplify the wiring path of the coil, but also help to improve the operational flexibility and efficiency during the winding process. In the specific implementation process, the warping of the terminal row can be achieved through precise mold settings and manufacturing processes, such as using a special molding process or adding a step to control the warping shape during the manufacturing process. For the control of the warping height, it is necessary to accurately calculate and adjust according to the actual application requirements and the mold setting parameters to ensure that the warping degree of the terminal row meets the operational requirements without affecting the stability and safety of the overall structure. By introducing the terminal row with a warping setting, this embodiment not only increases the practical function of the reactor winding mold, but also improves its convenience and safety in actual operation. The successful application of this setting reflects the in-depth consideration and innovative improvement of the setting details of the reactor winding mold, which helps to improve the efficiency of reactor production and the quality of products.

[0040] See also Figure 4 In a possible implementation manner, the starting terminal row 10 and the ending terminal row 4 are provided with a positioning groove 13 at one end corresponding to the positioning pin 6 , and the positioning groove is engaged with the positioning pin 6 .

[0041] On the basis of the previous embodiment, this embodiment introduces a setting in which the positioning groove 13 is combined with the positioning pin 6 to further improve the stability and reliability of the reactor winding mold. In this embodiment, the starting terminal row 10 and the ending terminal row 4 are respectively provided with positioning grooves matching the positioning pin 6, and the positioning pin 6 is connected with the positioning groove to achieve accurate fixation of the terminal row in the mold. This setting not only simplifies the assembly process of the mold, but also increases the structural strength of the mold, ensuring that the terminal row can be firmly fixed in a predetermined position during the winding operation to avoid displacement caused by vibration or improper operation. The combined use of the positioning groove and the positioning pin 6 provides a fast and reliable fixing solution, which greatly improves the convenience of use and production efficiency of the mold. During specific manufacturing, the size and shape of the positioning groove and the positioning pin 6 need to be precisely set to ensure that the two can be accurately matched. By using high-strength and wear-resistant materials to manufacture the positioning groove and the positioning pin 6, the stability and durability of the mold during long-term use can be further guaranteed. This embodiment optimizes the arrangement of the positioning groove 13 and the positioning pin 6, which not only improves the structural stability and operational convenience of the reactor winding mold, but also helps to shorten the production cycle of the product and improve production efficiency, and has important practical value for large-scale production of reactors.

[0042] In a possible implementation, the baffle is mounted on the two mold cores 1 by means of bolts 8 .

[0043] In the process of continuing to optimize the setting of the reactor winding mold, this embodiment pays special attention to the assembly method of the mold. By using the method of installing the baffle on the two mold cores 1 with bolts 8, the overall stability and reliability of the mold are further enhanced. In this embodiment, the baffle is matched with the corresponding threaded holes on the two mold cores 1 through the preset screw holes, and is fixed with bolts 8. The method of fixing with bolts 8 not only makes the assembly and disassembly of the mold easier and faster, but also can adjust the fastening force between the baffle and the mold core 1 according to the specific requirements of the winding operation to meet the use requirements under different working conditions. In addition, this fixing method is also convenient for daily maintenance and cleaning of the mold, and improves the service life and performance stability of the mold. In practical applications, suitable bolt 8 materials and specifications can be selected according to the size of the mold and the expected use environment to ensure the firmness and corrosion resistance of the connection. Through the optimization of materials and precise process control, the overall quality and winding efficiency of the mold can be further improved. This embodiment realizes the rapid assembly and disassembly of the reactor winding mold by introducing the setting of fixing the baffle with bolts 8, while ensuring the stability and reliability of the mold during use, providing a solid foundation for improving the efficiency and quality of reactor production.

[0044] In a possible implementation manner, the cross section of the mold shaft 7 is non-circular, and the two ends of the mold shaft that extend out are mounted on a rotating fixture, and the rotation of the rotating fixture drives the reactor winding mold to rotate.

[0045] This embodiment introduces the setting of a non-circular mold shaft 7, and a scheme for its use in conjunction with a rotary tooling. In this embodiment, the mold shaft 7 adopts a non-circular cross-section setting, and such a setting is intended to improve the transmission efficiency and stability when the mold shaft is connected to the rotary tooling. The non-circular mold shaft 7 can better fit with the mating parts on the rotary tooling to prevent relative sliding during the winding process, thereby ensuring the accuracy and quality of the winding. The two ends of the mold shaft 7 are mounted on the rotary tooling. When the rotary tooling is started, the reactor winding mold can be driven to rotate smoothly and evenly, realizing efficient and stable automatic winding operations. When selecting the material of the mold shaft 7 and setting its cross-sectional shape, factors such as transmission torque, processing cost and durability need to be considered to ensure that the mold shaft can meet the performance requirements during the winding process and has sufficient strength and durability. In addition, the setting of the rotary tooling also needs to be closely matched with the non-circular cross-section of the mold shaft 7 to ensure the efficient operation of the entire winding system. The non-circular mold shaft 7 and the rotary tooling of this embodiment significantly improve the use efficiency and winding quality of the reactor winding mold, which has important practical application value for realizing the automated production of the reactor.

[0046] In a possible implementation, there are two positioning pins 6 .

[0047] Based on the further improvement of the above-mentioned embodiment, this embodiment specifically points out that the number of positioning pins 6 in the reactor winding mold is two. The simplification of this setting makes the structure of the mold more compact and efficient, while ensuring the accurate positioning and fixation of the starting terminal row 10 and the ending terminal row 4. The setting scheme of adopting two positioning pins 6 not only helps to simplify the manufacturing and assembly process of the mold, but also facilitates the operator to quickly install and remove the terminal row, thereby improving the convenience of the winding operation. In addition, by optimizing the position and structural setting of the positioning pin 6, the terminal row can be firmly fixed, and the stability of the winding process and the quality of the winding product can be guaranteed. When implementing this setting, the material selection and size setting of the positioning pin 6 need to fully consider the force it bears and the use environment to ensure that the positioning pin 6 has sufficient strength and durability. At the same time, the mutual cooperation between the positioning pin 6 and the positioning groove should also be precisely controlled to ensure the accurate positioning and stable fixation of the terminal row. By adopting the setting of two positioning pins 6, this embodiment further optimizes the structure of the reactor winding mold, improves the practicality and operation convenience of the mold, and is conducive to improving the overall efficiency and product quality of the reactor production line.

[0048] The reactor winding mold of the utility model is assembled by a mold core, a baffle, a clamping plate, a terminal row positioning pin, a terminal row positioning plate and a fixing bolt. The winding positioning of the terminal row is realized by optimizing the left and right clamping plate structures. The mold core is composed of an upper and lower half. The two half models are assembled into a mold core as a whole through the left and right baffles. Then, the left and right clamping plates are installed at both ends of the mold core to assemble into a preliminary state of a mold. In order to ensure the fixation and positioning of the starting and ending rows during the winding process, two positioning grooves are opened on the clamping plate of the mold. When the terminal row is designed, a 12mm opening is opened at the tail of the terminal row. The notch is 10mm wide and 10mm deep. The terminal row positioning pin is inserted from the left positioning hole to the positioning notch at the end of the terminal row. The end of the terminal row is directly stuck in the wire outlet slot of the right clamping plate. In this way, both the left and right ends of the terminal row play a role in fixing and positioning. Then, when winding the wire, use glass fiber tape to fix the two terminal rows on the left and right, and then wind the wire. The terminal row end row is not flush with the starting row up and down due to the installation size problem. In order to ensure the installation size of the terminal row, the terminal row positioning plate is installed at the right clamping plate position to position the end terminal.
