Abstract
Description
Technical Field
[0001] The present application relates to the technical field of low-voltage electrical appliances, and in particular to a yoke of a release, a release and a switch device. Background Art
[0002] In the field of electrical technology, the safety and reliability of switch devices such as circuit breakers directly affect the stable operation of the power system. Among these switch devices, the release is an indispensable part, and the yoke on the release is the key. As a special electromagnetic component, the setting structure and performance characteristics of the yoke directly affect the working effect of the switch device.
[0003] The structural features of the traditional U-shaped yoke are mainly manifested in the slots for placing the static iron core and the notches for placing the coil skeleton. When the coil is energized, the yoke, the static iron core, the moving iron core and the air gap therebetween form a closed magnetic circuit. In this magnetic circuit, the yoke guides and enhances the magnetic field, so that the moving iron core moves toward the static iron core under the action of the magnetic field force. At the same time, in order to ensure that the moving and static iron cores remain separated under normal working conditions, a reaction spring is usually set to provide sufficient reaction force. However, in actual applications, when the loop current exceeds a certain value, the moving iron core needs to overcome the reaction force of the reaction spring and move toward the static iron core. In this process, the magnetic resistance from the yoke to the moving iron core directly affects the size of the electromagnetic attraction, and thus affects the breaking speed and breaking capacity of the product.
[0004] In order to reduce magnetic resistance and increase electromagnetic attraction, the existing release usually increases the number of turns of the coil. This setting will make the release larger. Utility Model Content
[0005] The present application provides a yoke of a release, a release and a switch device, which can reduce the magnetic resistance from the yoke to the moving iron core without increasing the number of coil turns and the current.
[0006] In a first aspect, the present application provides a yoke of a release, wherein the yoke can connect a moving iron core and a stationary iron core of the release, and the yoke includes a main body, a first mounting plate, and a second mounting plate.
[0007] The first mounting plate is arranged at the first end of the main body, the first mounting plate is arranged at an angle with the main body, a static mounting hole is opened on the first mounting plate, and the static iron core is installed in the static mounting hole.
[0008] The second mounting plate is arranged at the second end of the main body, the second mounting plate is arranged at an angle with the main body, a movable mounting hole is opened on the second mounting plate, and the movable iron core is directly or indirectly mounted in the movable mounting hole.
[0009] A punching flange is provided on the peripheral side of the movable mounting hole, and the punching flange can reduce the magnetic resistance of the yoke relative to the movable iron core.
[0010] The first mounting plate is arranged at the first end of the main body and is arranged at a certain angle to the main body. This arrangement not only increases the structural strength of the yoke, but also enables it to adapt to more installation environments. A static mounting hole is also provided on the first mounting plate for installing a static iron core. The static iron core is tightly connected to the yoke through the hole, thereby ensuring the stable transmission of the electromagnetic force.
[0011] Corresponding to the first mounting plate is a second mounting plate, which is arranged at the second end of the main body, and the second mounting plate is arranged at the same or similar angle as the main body. A dynamic mounting hole is provided on the second mounting plate for mounting a moving iron core. The moving iron core is movably connected to the yoke through the hole, thereby realizing the dynamic transmission of electromagnetic force. This arrangement enables the yoke to respond quickly according to demand, thereby improving the response speed of the entire system.
[0012] The surrounding side of the moving mounting hole is also provided with a punched flange. This setting can reduce the magnetic resistance of the yoke relative to the moving iron core, thereby increasing the electromagnetic attraction. This increased electromagnetic attraction enables the product to quickly disconnect the circuit, thereby improving the product's disconnection capacity. It is achieved that the magnetic resistance from the yoke to the moving iron core is reduced without increasing the number of coil turns and current.
[0013] In some examples, the punched flange is folded toward the second mounting plate in a direction away from the first mounting plate, or the punched flange is folded toward the second mounting plate in a direction close to the first mounting plate.
[0014] The punching flange can reduce the magnetic resistance of the yoke relative to the moving iron core. This can increase the electromagnetic attraction. This can achieve rapid product disconnection. This can improve the product's disconnection capacity. At this time, the yoke has a smaller assembly space due to the setting of the punching flange. The yoke can be replaced by increasing the size of the yoke or reducing the size of the release body. When reducing the size of the release body, the assembly skeleton and the coil structure can be adjusted to make way for the punching flange.
[0015] In some examples, along the direction in which the second mounting plate is away from the first mounting plate, with the second mounting plate as a reference, the height of the blanking flange is lower than the lowest height of the moving iron core.
[0016] Since the height of the blanking flange is set to be lower than the lowest height of the moving iron core, the blanking flange can always maintain its function during the movement of the moving iron core. This means that no matter how the moving iron core expands and contracts, the blanking flange can effectively play its role, thereby reducing the magnetic resistance of the yoke relative to the moving iron core. The reduction of magnetic resistance helps to improve the electromagnetic attraction, making the release more stable and efficient during the attraction and release process.
[0017] In some examples, the static mounting hole and the dynamic mounting hole are both "C"-shaped holes, the punching flange is arranged at the edge of the dynamic mounting hole, and the shape of the punching flange is adapted to the shape of the dynamic mounting hole.
[0018] The "C"-shaped hole has a larger opening and a narrower neck. This structure makes the installation process more convenient and also enhances the stability of the installation. In addition, the "C"-shaped hole also has good elasticity, which can absorb and alleviate the vibration and impact generated during the movement of the moving iron core to a certain extent, thereby increasing the service life of the release.
[0019] In some examples, the magnetic yoke further includes a third mounting plate, the third mounting plate is disposed on the same side of the first mounting plate, the static contact plate is mounted on the third mounting plate, and a static contact point is disposed on the static contact plate.
[0020] The third mounting plate is used to support and fix the static contact plate. As a part of the magnetic yoke, the static contact plate can contact or separate with the moving contact under the action of electromagnetic force to realize the on-off control of the current. Therefore, the installation position and stability of the static contact plate have a vital influence on the working performance of the magnetic yoke.
[0021] On the third mounting plate, the static contact plate is precisely mounted and fixed by screws or other fasteners. Static contacts are set on the static contact plate, which are usually made of conductive materials such as copper or silver to ensure good conductivity. The shape and number of static contacts will be set according to specific application requirements to meet different current and voltage requirements.
[0022] In some examples, the releaser also includes an assembly frame, and the static iron core, the moving iron core and the assembly frame cooperate to form a releaser body, and a coil is surrounded by the circumference of the releaser, a first end of the coil is electrically connected to the static contact plate, and a second end of the coil is connected to a terminal block.
[0023] The release includes an assembly frame, which supports and installs the static iron core and the moving iron core in the entire release structure. The assembly frame is designed to be delicate and strong, and can effectively support and fix the various components of the release, ensuring the stability and reliability of the entire release body.
[0024] In the main body of the release, the static iron core and the moving iron core are two indispensable parts. The interaction between them is the key to the release to achieve its function. Through a series of precise settings and assembly processes, the static iron core, the moving iron core and the assembly frame are perfectly matched, and together they constitute the core structure of the main body of the release.
[0025] The release is also surrounded by coils. These coils are key components for the electrical control of the release. They are usually wound with insulated wires and have a certain number of turns and resistance. When current flows through the coil, a magnetic field is generated, which interacts with the magnetic field between the static iron core and the moving iron core, thereby controlling the release.
[0026] In some examples, a clearance groove is provided on the main body, and the clearance groove can avoid the tripping body of the releaser, and there is a gap between the coil on the tripping body and the bottom of the clearance groove.
[0027] In some specific practical application examples, a clearance groove structure is provided on the main body. The main function of the clearance groove is to avoid the key component in the releaser, that is, the release body. By opening or punching the clearance groove on the main body, it can be ensured that the release body can move smoothly during operation without being hindered by the main body.
[0028] In a second aspect, the present application provides a release, comprising a yoke of the above-mentioned release and a release body, wherein the release body is mounted on the yoke.
[0029] The release with the above-mentioned yoke reduces the magnetic resistance from the yoke to the moving iron core without increasing the number of coil turns and the current. Specifically, a punching flange is also provided on the circumferential side of the moving mounting hole. This arrangement can reduce the magnetic resistance of the yoke relative to the moving iron core, thereby increasing the electromagnetic attraction. This increased electromagnetic attraction enables the product to quickly disconnect the circuit, thereby improving the product's disconnection capacity. It achieves the reduction of the magnetic resistance from the yoke to the moving iron core without increasing the number of coil turns and the current.
[0030] In a third aspect, the present application provides a switch device, comprising a release as described above and a housing, wherein the housing has a receiving cavity, and the release is installed in the receiving cavity.
[0031] The switch device with the above-mentioned release realizes the reduction of the magnetic resistance from the yoke to the moving iron core without increasing the number of coil turns and the current. Specifically, a punching flange is also provided on the peripheral side of the moving mounting hole. This arrangement can reduce the magnetic resistance of the yoke relative to the moving iron core, thereby increasing the electromagnetic attraction. This increased electromagnetic attraction enables the product to quickly disconnect the circuit, thereby improving the product's disconnection capacity. It is achieved that the magnetic resistance from the yoke to the moving iron core is reduced without increasing the number of coil turns and the current. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.
[0041] In the relevant technical field, a switch device such as a circuit breaker is provided with a release, and a yoke is provided on the release. The yoke is usually U-shaped.
[0042] The existing U-shaped yoke has a slot for placing the static iron core and a notch for placing the coil frame. At the same time, after the coil is energized, the yoke, the static iron core, the moving iron core and their air gap form a magnetic circuit. Under the action of the reaction spring, the moving and static iron cores remain separated. When the loop current exceeds a certain value, the moving iron core overcomes the reaction force of the reaction spring and moves toward the static iron core, while driving the push rod to move with it, unlocking the lock of the circuit breaker and pushing the moving contact bracket to move. The product's breaking function is realized.
[0043] The utility model provides a U-shaped yoke structure, which reduces the magnetic resistance from the yoke to the moving iron core and increases the electromagnetic attraction without increasing the number of coil turns and current by punching a flange structure on the yoke, thereby achieving rapid product disconnection and improving the product disconnection capacity.
[0044] In the field of electrical technology, circuit breakers and other switching devices play a vital role. Their safety and reliability directly affect the stable operation of the power system. Among these switching devices, the release is an indispensable part, and the yoke on the release is the key. As a special electromagnetic component, the setting structure and performance characteristics of the yoke directly affect the working effect of the switching device.
[0045] The structural features of the traditional U-shaped yoke are mainly characterized by a slot for placing the static iron core and a notch for placing the coil frame. When the coil is energized, the yoke, the static iron core, the moving iron core and the air gap between them together form a closed magnetic circuit. In this magnetic circuit, the yoke guides and enhances the magnetic field, so that the moving iron core moves toward the static iron core under the action of the magnetic field force. At the same time, in order to ensure that the moving and static iron cores remain separated under normal working conditions, a reaction spring is usually set to provide sufficient reaction force.
[0046] However, in actual applications, when the loop current exceeds a certain value, the moving iron core needs to overcome the reaction force of the reaction spring and move toward the static iron core. In this process, the magnetic resistance from the yoke to the moving iron core directly affects the size of the electromagnetic attraction, and thus affects the breaking speed and breaking capacity of the product. Therefore, how to reduce the magnetic resistance and increase the electromagnetic attraction becomes the key to improving product performance.
[0047] To address this problem, the utility model provides a new U-shaped yoke structure. This structure reduces the magnetic resistance from the yoke to the moving iron core without increasing the number of coil turns and current by punching a flange structure on the yoke. This innovative setting significantly improves the electromagnetic attraction, thereby achieving rapid disconnection of the product and improving the product's disconnection capacity.
[0048] Specifically, the flanging structure increases the cross-sectional area of the yoke, thereby reducing magnetic resistance. At the same time, the flanging structure can also optimize the distribution of the magnetic field, making the magnetic field more concentrated and more uniform. These improvements not only increase the magnitude of the electromagnetic suction force, but also make the suction force more stable and more reliable.
[0049] In addition, this new U-shaped yoke structure also has the advantages of simple manufacturing process and low cost. The flange structure can be made through simple processing techniques such as stamping, without adding additional equipment or process steps. This greatly reduces the production cost, making this new yoke structure more widely promoted in practical applications.
[0050] In summary, the U-shaped yoke structure provided by the utility model reduces magnetic resistance and increases electromagnetic attraction without increasing the number of coil turns and current through innovative settings and optimization, thereby improving the breaking speed and breaking capacity of the product. This new yoke structure has the advantages of simple manufacturing process and low cost, and provides new ideas and methods for the development of the field of electrical technology.
[0051] The utility model provides an innovative U-shaped yoke structure to solve the problems in the prior art. The structure punches a flange on the yoke to significantly reduce the magnetic resistance from the yoke to the moving iron core without increasing the number of coil turns and current, thereby effectively increasing the electromagnetic attraction. This innovative setting not only optimizes the magnetic circuit structure, but also improves the breaking capacity of the product, achieving the effect of rapid breaking of the product.
[0052] First, let's take a closer look at the uniqueness of this U-shaped yoke structure. A punched flange structure is added to the connection line between the yoke and the moving iron core. The setting of this flange structure changes the direction of the magnetic circuit, making the magnetic flux pass through the moving iron core more concentrated, thereby reducing the magnetic resistance. The reduction in magnetic resistance means that under the same current conditions, the electromagnetic attraction is enhanced. This enhancement not only improves the product's breaking speed, but also makes the breaking process more stable and reliable.
[0053] In addition, this U-shaped yoke structure also has significant economic benefits. Without increasing materials, costs and assembly processes, the product's breaking capacity has been significantly improved. This means that manufacturers can optimize product performance without investing more resources. At the same time, since the manufacturing process of the flange structure is relatively simple, it also reduces production costs and improves production efficiency.
[0054] In order to further verify the superior performance of this U-shaped yoke structure, a series of empirical studies were conducted. The experimental results show that under the same conditions, the breaking speed of the product using this structure is significantly improved compared with the traditional structure. At the same time, the breaking capacity of the product has also been significantly enhanced, making the product more stable and reliable during use.
[0055] In summary, the U-shaped yoke structure provided by the utility model has significant technical advantages and economic benefits. It not only optimizes the magnetic circuit structure and improves the electromagnetic attraction, but also achieves the effect of rapid product disconnection. At the same time, since there is no need to increase materials, costs and assembly processes, manufacturers can more efficiently produce products with superior performance. Therefore, this U-shaped yoke structure has broad application prospects and market demand in related fields.
[0056] To solve the above technical problems, please refer to Figure 1-Figure 5 As shown, the first aspect of the present application proposes a yoke 100 of a release, which can reduce the magnetic resistance from the yoke 100 to the moving iron core 220 without increasing the number of turns and current of the coil 300.
[0057] Reference Figure 1 and Figure 2 In some examples, the yoke 100 can connect the moving iron core 220 and the stationary iron core 210 of the release, and the yoke 100 includes a main body 110 , a first mounting plate 120 and a second mounting plate 130 .
[0058] The first mounting plate 120 is disposed at a first end of the main body 110 . The first mounting plate 120 and the main body 110 are disposed at an angle. A static mounting hole 121 is defined on the first mounting plate 120 , and the static iron core 210 is mounted in the static mounting hole 121 .
[0059] The second mounting plate 130 is disposed at the second end of the main body 110, and the second mounting plate 130 is disposed at an angle to the main body 110. A movable mounting hole 131 is provided on the second mounting plate 130, and the movable iron core 220 is directly or indirectly mounted in the movable mounting hole 131. The movable iron core 220 can be specifically mounted on an assembly frame 230, and the assembly frame 230 is then mounted in the movable mounting hole 131.
[0060] A punching flange 132 is provided around the movable mounting hole 131 . The punching flange 132 can reduce the magnetic resistance of the yoke 100 relative to the movable iron core 220 .
[0061] The magnetic yoke 100 of the present application has a unique structure and function, and can effectively improve the working efficiency and stability of the entire system.
[0062] The overall structure of the yoke 100 is in a "U" shape, which enables it to firmly connect the moving iron core 220 and the static iron core 210, thereby achieving effective transmission of electromagnetic force. The yoke 100 mainly includes three parts: a main body 110, a first mounting plate 120 and a second mounting plate 130. Among them, the main body 110 usually exists as a horizontal plate, which plays a supporting and connecting role. The first mounting plate 120 and the second mounting plate 130 are respectively arranged at both ends of the main body 110, and exist as vertical plates, which further enhances the overall stability of the yoke 100.
[0063] The first mounting plate 120 is disposed at the first end of the main body 110 and is disposed at a certain angle to the main body 110. This arrangement not only increases the structural strength of the yoke 100, but also enables it to adapt to more installation environments. A static mounting hole 121 is also provided on the first mounting plate 120 for mounting a static iron core 210. The static iron core 210 is tightly connected to the yoke 100 through the hole, thereby ensuring the stable transmission of the electromagnetic force.
[0064] Corresponding to the first mounting plate 120 is a second mounting plate 130, which is arranged at the second end of the main body 110, and the second mounting plate 130 is arranged at the same or similar angle as the main body 110. A movable mounting hole 131 is provided on the second mounting plate 130 for mounting the moving iron core 220. The moving iron core 220 is movably connected to the yoke 100 through the hole, thereby realizing the dynamic transmission of electromagnetic force. This arrangement enables the yoke 100 to respond quickly according to demand, thereby improving the response speed of the entire system.
[0065] A punched flange 132 is also provided around the movable mounting hole 131. This arrangement can reduce the magnetic resistance of the yoke 100 relative to the movable iron core 220, thereby increasing the electromagnetic attraction. This increased electromagnetic attraction enables the product to quickly disconnect the circuit, thereby improving the product's disconnection capacity. It is achieved that the magnetic resistance from the yoke 100 to the movable iron core 220 is reduced without increasing the number of turns and current of the coil 300.
[0066] In addition, the provision of the punched flange 132 also enhances the strength and stability of the dynamic mounting hole 131 , further improving the service life and reliability of the yoke 100 .
[0067] The punching flange 132 is formed by punching or folding the metal plate to a specific shape and height. This process is widely used in the manufacturing industry, especially in the automotive, home appliance, hardware and other industries. The thickness of the punching flange 132 is usually the same or similar to the thickness of the yoke 100, which can ensure the overall strength and stability.
[0068] In the process of making the punching flange 132, its height is an important parameter. According to the setting requirements of the product and the actual use scenario, the height of the punching flange 132 can be flexibly adjusted. A higher flange can provide better support and protection, while a lower flange may be more suitable for some occasions with higher space requirements. Therefore, in the process of making the punching flange 132, it is necessary to accurately set the height according to actual needs.
[0069] In addition to the height, the shape of the punching flange 132 is also a key factor. In practical applications, the shape of the punching flange 132 can be adjusted according to the adaptability of the dynamic mounting hole 131. For example, when the position or size of the mounting hole changes, the shape of the punching flange 132 also needs to be adjusted accordingly to ensure that the mounting hole and the flange fit tightly and stably. In addition, the shape of the punching flange 132 can also be set independently, and the best flange shape can be determined according to the overall setting and functional requirements of the product.
[0070] The production process of the punching flange 132 involves many details and technical points. During the punching or folding process, the deformation and warping of the sheet need to be strictly controlled to ensure the quality and accuracy of the flange. At the same time, it is also necessary to select appropriate molds and process parameters to ensure that the size and shape of the punching flange 132 meet the requirements. In addition, it is necessary to fully understand the material and performance of the sheet so as to make reasonable adjustments and optimizations during the production process.
[0071] Reference Figure 3 In some examples, the punched flange 132 is folded toward the second mounting plate 130 away from the first mounting plate 120. The punched flange 132 can reduce the magnetic resistance of the yoke 100 relative to the moving iron core 220. This increases the electromagnetic attraction. The product can be quickly disconnected. The product's disconnection capacity is improved. At this time, the punched flange 132 has no effect on the assembly space of the yoke 100, so the yoke 100 can be adapted to the existing release body 200, and the yoke 100 can be replaced without changing the structure of the existing release body 200.
[0072] In some specific engineering practices, the application of the punching flange 132 technology is often encountered. In these cases, the punching flange 132 is set to be folded toward the second mounting plate 130 away from the first mounting plate 120. This folding method not only ensures the functionality of the punching flange 132, but also makes the overall structure more compact and beautiful.
[0073] The application of the blanking flange 132 plays a vital role in reducing the magnetic resistance of the yoke 100 relative to the moving iron core 220. The reduction of magnetic resistance means the increase of electromagnetic attraction, thereby realizing the rapid disconnection function of the product. This feature is particularly important in electrical equipment such as electrical switches and relays, because it can significantly improve the disconnection capacity of the product and ensure that the equipment can work stably and reliably under extreme conditions.
[0074] In addition, the setting of the blanking flange 132 has another significant advantage, that is, it has no effect on the assembly space of the yoke 100. This means that the yoke 100 can be easily adapted to the existing release body 200 without any change to the structure of the release body 200. This compatibility makes the replacement of the yoke 100 easier, reduces maintenance costs, and improves production efficiency.
[0075] From the perspective of practical application, the application of blanking and flanging 132 not only improves the performance of the product, but also reduces the production cost. In today's increasingly competitive market, this undoubtedly wins more competitive advantages for enterprises. At the same time, the continuous innovation and improvement of blanking and flanging 132 technology has also injected new vitality into the development of the entire industry.
[0076] In short, as an effective technical means, the punching and flanging 132 plays an important role in the manufacture and upgrading of electrical equipment. By reducing magnetic resistance, increasing electromagnetic attraction, improving breaking capacity and maintaining the compatibility of assembly space, the punching and flanging 132 technology provides a strong guarantee for the performance and reliability of electrical equipment. In the future, with the continuous advancement of technology and the continuous expansion of applications, there is reason to believe that the punching and flanging 132 technology will play a greater role in more fields.
[0077] In some examples, the punched flange 132 is folded toward the second mounting plate 130 close to the first mounting plate 120. The punched flange 132 can reduce the magnetic resistance of the yoke 100 relative to the moving iron core 220. In turn, the electromagnetic attraction is increased. The product is quickly disconnected. The product's disconnection capacity is improved. At this time, the yoke 100 has a smaller assembly space due to the setting of the punched flange 132. The yoke 100 can be replaced by increasing the size of the yoke 100 or reducing the size of the release body 200. When reducing the size of the release body 200, the structure of the assembly skeleton 230 and the coil 300 can be adjusted to make way for the punched flange 132.
[0078] In some examples of engineering settings and practical applications, a specific structure is often encountered, namely, the punching flange 132 structure. This structure is applied between specific components to achieve specific functional requirements. Specifically, when the punching flange 132 is folded toward the second mounting plate 130 and close to the first mounting plate 120, its unique setting characteristics are fully reflected.
[0079] The application of the punching flange 132 is first reflected in its effect of reducing magnetic resistance. In electromagnetic equipment, magnetic resistance is one of the key factors affecting the size of magnetic flux. By setting the punching flange 132, the magnetic resistance of the yoke 100 relative to the moving iron core 220 can be effectively reduced, thereby increasing the electromagnetic attraction. This increased electromagnetic attraction not only helps to improve the performance of the product, but also enables the rapid disconnection of the product at a critical moment.
[0080] In addition, the application of the punching flange 132 also improves the breaking capacity of the product. In the working process of electromagnetic equipment, the breaking capacity is a crucial indicator. By optimizing the setting of the punching flange 132, the breaking speed and accuracy of the product can be further improved to meet the needs of different application scenarios.
[0081] At the same time, the setting of the punching flange 132 also optimizes the assembly space of the yoke 100. Due to the existence of the punching flange 132, the assembly space of the yoke 100 is effectively reduced. This means that while maintaining the product performance, the volume and weight of the product can be further reduced, thereby improving the portability and ease of use of the product.
[0082] It is worth noting that the application of the blanking flange 132 also provides more setting possibilities. For example, the electromagnetic performance of the product can be further improved by increasing the size of the yoke 100; or the structural layout of the product can be further optimized by reducing the size of the release body 200. These setting changes not only enrich the types and functions of the products, but also provide more options.
[0083] In summary, the punching flange 132, as a unique structural setting, plays an important role in electromagnetic equipment. By reducing magnetic resistance, increasing electromagnetic attraction, improving breaking capacity, optimizing assembly space, and providing more setting possibilities, the punching flange 132 brings many advantages to the setting and manufacturing of electromagnetic equipment. With the continuous advancement of technology and the expansion of application fields, there is reason to believe that the punching flange 132 will play a more important role in the future and contribute more to the development of electromagnetic equipment.
[0084] Reference Figure 4 and Figure 5In some examples, along the direction of the second mounting plate 130 away from the first mounting plate 120 , with the second mounting plate 130 as a reference, the height of the blanking flange 132 is lower than the lowest height of the moving iron core 220 .
[0085] The second mounting plate 130 in the release is arranged opposite to the first mounting plate 120. In the direction in which the second mounting plate 130 is away from the first mounting plate 120, the arrangement of the punching flange 132 is particularly critical. The punching flange 132 is an edge structure formed by punching and folding on the plate, which has the function of enhancing the strength of the plate and guiding the magnetic field distribution, effectively improving the stability of the electromagnetic attraction, and thus improving the performance and reliability of the release.
[0086] Specifically, with the second mounting plate 130 as a reference, the height of the punched flange 132 is set to be lower than the lowest height of the moving iron core 220. The moving iron core 220, as a movable component in the release, can move relative to the moving mounting hole 131 on the second mounting plate 130, that is, it can be relatively extended and retracted in the moving mounting hole 131. Therefore, the height of the moving iron core 220 can change during operation.
[0087] Since the height of the punching flange 132 is set to be lower than the lowest height of the moving iron core 220, the punching flange 132 can always maintain its function during the movement of the moving iron core 220. This means that no matter how the moving iron core 220 is stretched or contracted, the punching flange 132 can effectively play its role, thereby reducing the magnetic resistance of the yoke 100 relative to the moving iron core 220. The reduction of magnetic resistance helps to improve the electromagnetic attraction, making the release more stable and efficient during the attraction and release process.
[0088] The punching flange 132 is an arc-shaped structure. After the punching flange 132 is set as an arc-shaped structure, the magnetic resistance of the yoke 100 relative to the moving iron core 220 can be further reduced, thereby increasing the electromagnetic attraction, achieving rapid product disconnection, and improving the product's disconnection capacity.
[0089] In the mechanical field, the punching flange 132 is an important manufacturing process used to create specific shapes and structures in various products. In some specific application scenarios, the punching flange 132 is set as an arc structure, which not only beautifies the appearance of the product, but also further enhances its functionality.
[0090] The arc-shaped structure of the punched flange 132 significantly reduces the magnetic resistance between the yoke 100 and the moving iron core 220. Magnetic resistance is the resistance encountered by a magnetic field when passing through a certain medium, and its magnitude directly affects the strength and distribution of the magnetic field. When the punched flange 132 adopts an arc-shaped structure, the magnetic field can pass more smoothly, reducing the magnetic resistance, thereby enhancing the electromagnetic attraction.
[0091] The increase of electromagnetic attraction has a significant impact on the performance improvement of the product. In electromagnetic equipment, the magnitude of electromagnetic attraction is directly related to the breaking capacity of the product. When the electromagnetic attraction is large enough, the product can complete the breaking action more quickly and accurately, improving work efficiency and reliability.
[0092] In addition, the arc-shaped structure of the punching flange 132 is also helpful to optimize the overall structure of the product. The arc-shaped structure has certain elasticity and toughness, which can alleviate the impact and vibration of the product during operation to a certain extent and extend the service life of the product.
[0093] The arc-shaped structure of the blanking flange 132 is not set randomly, but is based on in-depth theoretical analysis and empirical research. The designers have continuously optimized the parameters and shape of the arc-shaped structure through a large number of experiments and tests to achieve the best magnetic resistance reduction effect and electromagnetic attraction enhancement effect.
[0094] The arc-shaped structure of the blanking flange 132 has significant advantages in reducing magnetic resistance, increasing electromagnetic attraction, and improving product breaking capacity. This setting not only improves product performance, but also optimizes product structure, bringing more possibilities for the manufacture and application of electromagnetic equipment.
[0095] Reference Figure 4 and Figure 5 In some examples, the static mounting hole 121 and the dynamic mounting hole 131 are both “C”-shaped holes, and the punching flange 132 is arranged at the edge of the dynamic mounting hole 131 , and the shape of the punching flange 132 is adapted to the shape of the dynamic mounting hole 131 .
[0096] In some practical application cases, it can be seen that the static mounting hole 121 and the dynamic mounting hole 131 are both set in a "C"-shaped hole structure. This "C"-shaped hole setting not only has a beautiful appearance, but also shows significant advantages in functionality and practicality. As important components of the mechanical structure, the rationality of the setting of the static mounting hole 121 and the dynamic mounting hole 131 is directly related to the stability and work efficiency of the overall structure.
[0097] The static mounting hole 121 is usually used to fix mechanical parts, such as used to fix the static iron core 210 in the present application to ensure that it maintains a stable position during operation; the dynamic mounting hole 131 is more used to connect and rotate parts to achieve various complex mechanical movements, such as used to install the relatively slidable dynamic iron core 220 in the present application.
[0098] The "C"-shaped hole has a larger opening and a narrower neck. This structure makes the installation process more convenient and also enhances the stability of the installation. In addition, the "C"-shaped hole also has good elasticity, which can absorb and alleviate the vibration and impact generated during the movement of the moving iron core to a certain extent, thereby increasing the service life of the release.
[0099] In the arrangement of the static mounting hole 121 and the dynamic mounting hole 131, the punching flange 132 is arranged at the edge of the dynamic mounting hole 131, and the shape of the punching flange 132 is adapted to the shape of the dynamic mounting hole 131. This arrangement enables the punching flange 132 to fit tightly to the edge of the dynamic mounting hole 131, thereby effectively preventing dislocation and looseness during the installation process. At the same time, the punching flange 132 also has a certain elasticity and toughness, which can play a certain buffering role during the installation process and reduce friction and wear between mechanical parts.
[0100] In some examples, the yoke 100 further includes a third mounting plate 140 , which is disposed on the same side of the first mounting plate 120 . A stationary contact plate 400 is mounted on the third mounting plate 140 , and a stationary contact point 410 is disposed on the stationary contact plate 400 .
[0101] The yoke 100 generally further includes a third mounting plate 140 , which is located on the same side as the first mounting plate 120 , with a certain distance and angle maintained between the two to meet the stability and functionality requirements of the overall structure.
[0102] The third mounting plate 140 is used to support and fix the stationary contact plate 400. As a part of the magnetic yoke 100, the stationary contact plate 400 can contact or separate with the moving contact under electromagnetic action to achieve the on-off control of the current. Therefore, the installation position and stability of the stationary contact plate 400 have a crucial influence on the working performance of the magnetic yoke 100.
[0103] On the third mounting plate 140, the stationary contact plate 400 is precisely mounted and fixed by screws or other fasteners. The stationary contact plate 400 is provided with stationary contacts 410, which are usually made of conductive materials, such as copper or silver, to ensure good conductive properties. The shape and number of the stationary contacts 410 are set according to specific application requirements to meet different current and voltage requirements.
[0104] In addition to the above basic structure, the yoke 100 may also include other auxiliary components, such as insulating materials, heat dissipation devices, etc., to improve its working performance and safety. The addition of these components makes the setting of the yoke 100 more perfect and can better adapt to various complex working environments.
[0105] In practical applications, the performance of the yoke 100 will be affected by many factors, such as temperature, humidity, electromagnetic interference, etc. Therefore, when setting and manufacturing the yoke 100, it is necessary to fully consider these factors and take corresponding measures to protect and optimize them. At the same time, through empirical research and statistical analysis, we can further understand the working mechanism and performance characteristics of the yoke 100, and provide more reliable technical support for its application in various fields.
[0106] In some examples, the release device further includes an assembly frame 230, and the static iron core 210, the moving iron core 220 and the assembly frame 230 cooperate to form a release device body 200. The release device is surrounded by a coil 300, and the coil 300 can be specifically wound around the outer peripheral surface of the assembly frame 230. The number of windings of the coil 300 is set according to actual needs. The first end of the coil 300 is electrically connected to the static contact plate 400, and the second end of the coil 300 is connected to the wiring board 500.
[0107] The release includes an assembly frame 230, which plays a role in supporting and installing the static iron core 210 and the moving iron core 220 in the entire release structure. The assembly frame 230 is exquisitely and firmly arranged, and can effectively support and fix the various components of the release, ensuring the stability and reliability of the entire release body 200.
[0108] In the release body 200, the static iron core 210 and the moving iron core 220 are two indispensable parts. The interaction between them is the key to the release to achieve its function. The static iron core 210 and the moving iron core 220 and the assembly frame 230 are perfectly matched through a series of precise settings and assembly processes, and together constitute the core structure of the release body 200.
[0109] The release is also surrounded by coils 300. These coils 300 are key components for realizing electrical control of the release. They are usually wound by insulated wires and have a certain number of turns and resistance value. When current is passed through the coils 300, a magnetic field is generated, which interacts with the magnetic field between the static iron core 210 and the moving iron core 220, thereby realizing control of the release.
[0110] Specifically, the first end of the coil 300 is electrically connected to the stationary contact plate 400. The stationary contact plate 400 is one of the connection points between the release and the external circuit, and it can introduce the current of the external circuit into the coil 300. When the external circuit is closed, the current flows into the coil 300 through the stationary contact plate 400, causing the coil 300 to generate a magnetic field.
[0111] The second end of the coil 300 is connected to the terminal block 500. The terminal block 500 is another key component inside the release, and the terminal block 500 can connect the other end of the coil 300 to another part of the external circuit. Through the terminal block 500, the current of the coil 300 can be effectively controlled and adjusted, thereby achieving precise control of the release function.
[0112] In practical applications, this structural setting of the release can effectively realize the protection and control functions of the circuit. When abnormal conditions such as overcurrent or short circuit occur in the circuit, the release can quickly cut off the circuit to prevent equipment damage and safety accidents such as fire. At the same time, the release can also be operated manually or automatically as needed to achieve flexible control of the circuit.
[0113] In some examples, a clearance groove is provided on the main body 110 , and the clearance groove can avoid the tripping body of the releaser, and there is a gap between the coil 300 on the tripping body and the bottom of the clearance groove.
[0114] In some specific practical application examples, a clearance groove structure is provided on the main body 110. The main function of the clearance groove is to avoid the key component in the releaser, that is, the release body. By opening or punching the clearance groove on the main body 110, it can be ensured that the release body can move smoothly during operation without being hindered by the main body 110.
[0115] The setting of the clearance groove can be a groove dug out or punched out on the main body 110. In practical applications, it is necessary to consider the relative position relationship between the trip body and the clearance groove, as well as the size of the gap between them. The size of this gap is crucial because the clearance groove directly affects the movement performance and stability of the trip body. The moving iron core 220 in the present application can be positioned using the static iron core 210 and the yoke 100. Alternatively, the moving iron core 220 in the present application can be positioned using the coil 300 skeleton and the yoke 100.
[0116] Therefore, during the setting and manufacturing process, the size of this gap needs to be determined through precise measurement and calculation. At the same time, the materials and processes of the trip body and the clearance groove need to be strictly controlled to ensure that the cooperation between them can achieve the best state.
[0117] In addition, the coil 300 on the trip body is also one of the important parts that need attention. As an important part of the trip, the performance of the coil 300 directly affects the overall performance of the trip. Therefore, during the setting and manufacturing process, it is necessary to ensure that there is enough clearance between the coil 300 and the bottom of the give way slot to prevent the coil 300 from being squeezed or damaged during operation.
[0118] In order to better understand the working principle and advantages of this structure, we can analyze it in combination with some actual application scenarios. For example, in some devices that need to perform frequent tripping operations, the use of this setting with a clearance slot can effectively improve the reliability and stability of the tripper and reduce the probability of failure. At the same time, this setting can also improve the operating efficiency and service life of the equipment, bringing a better user experience to users.
[0119] In a second aspect, the present application provides a release, including the above-mentioned yoke 100 of the release and a release body, wherein the release body is mounted on the yoke 100 .
[0120] The release device with the above-mentioned yoke 100 realizes the reduction of the magnetic resistance from the yoke 100 to the moving iron core 220 without increasing the number of turns and current of the coil 300. Specifically, a punching flange 132 is also provided on the peripheral side of the moving mounting hole 131. This arrangement can reduce the magnetic resistance of the yoke 100 relative to the moving iron core 220, thereby increasing the electromagnetic attraction. This increased electromagnetic attraction enables the product to quickly disconnect the circuit, thereby improving the product's disconnection capacity. It is achieved that the magnetic resistance from the yoke 100 to the moving iron core 220 is reduced without increasing the number of turns and current of the coil 300.
[0121] In a third aspect, the present application provides a switch device, including the above-mentioned release and a housing 600, wherein the housing 600 has a receiving cavity, and the release is installed in the receiving cavity.
[0122] The switch device with the above-mentioned release realizes the reduction of the magnetic resistance from the yoke 100 to the moving iron core 220 without increasing the number of turns and current of the coil 300. Specifically, a punching flange 132 is also provided on the peripheral side of the moving mounting hole 131. This arrangement can reduce the magnetic resistance of the yoke 100 relative to the moving iron core 220, thereby increasing the electromagnetic attraction. This increased electromagnetic attraction enables the product to quickly disconnect the circuit, thereby improving the product's disconnection capacity. It is achieved that the magnetic resistance from the yoke 100 to the moving iron core 220 is reduced without increasing the number of turns and current of the coil 300.
