Description

Technical Field

[0001] This application relates to the field of product packaging technology, specifically to a protective structure and a packaging structure for a circuit breaker. Background Technology

[0002] Molded case circuit breakers are also known as modular circuit breakers. The main components of a molded case circuit breaker are generally sealed in a plastic housing. Molded case circuit breakers can also be equipped with additional modules to enable corresponding circuit protection functions, such as auxiliary contacts, undervoltage release devices, and shunt trip devices.

[0003] These additional modules are usually installed on the plastic housing of the molded case circuit breaker and protrude from the housing. This makes it easy for the additional modules to be bumped or knocked off during transportation, which can damage or cause them to fall off and affect the normal use of the molded case circuit breaker. Utility Model Content

[0004] The purpose of this application is to provide a protective structure and a packaging structure for circuit breakers, which can improve the protection effect of circuit breaker products and reduce the risk of damage to circuit breaker products due to impacts.

[0005] In a first aspect, embodiments of this application provide a protective structure, which is formed by folding cardboard through preset creases. The product includes a protrusion that protrudes from the surface of the product. The protective structure includes a first side plate, a second side plate, a third side plate, and a fourth side plate. The first side plate and the second side plate are arranged opposite to each other, and the third side plate and the fourth side plate are arranged opposite to each other.

[0006] The second side panel includes a first folding plate and a second folding plate spaced apart. Both the first and second folding plates fold towards the first side panel and are positioned opposite each other. A cover plate is disposed on the side of the second side panel and can cover the space between the first and second side panels. The first folding plate, the second folding plate, the cover plate, and the first side panel together form a protective groove that is adapted to the protrusion.

[0007] Based on the above embodiments of this application, by setting a first folding plate, a second folding plate, and a cover plate on the protective structure formed by the first side plate, the second side plate, the third side plate, and the fourth side plate, a protective groove is formed on the protective structure. The protective groove can accommodate the protrusions on the product, so that the protective structure can not only protect the main body of the product, but also protect the protrusions on the product separately, effectively improving the protective effect of the protective structure on the product, reducing the risk of damage caused by bumps to the protrusions, and facilitating the safe transportation of the product.

[0008] In some examples, the first folding panel includes a first support edge that abuts against the side of the first side panel near the second side panel. The second folding panel includes a second support edge that abuts against the side of the first side panel near the second side panel.

[0009] Based on the above embodiments of this application, the first support edge abutting against the first side plate means that the first folding plate is supported between the first side plate and the second side plate, and the second support edge abutting against the first side plate means that the second folding plate is also supported between the first side plate and the second side plate. In this way, the first folding plate and the second folding plate can stably support the first side plate and the second side plate, prevent the protective structure from deforming, thereby improving the structural stability of the protective groove and ensuring that the protective groove can provide reliable protection.

[0010] In some examples, the first folding plate also includes a first side and a second side, which are located on opposite sides of the first folding plate. The first side is the side of the second side plate that is away from the cover plate, and the second side is the side of the first folding plate that is close to the cover plate. The cover plate can abut against the second side when it is closed.

[0011] The second folding plate also includes a third side and a fourth side. The third side and the fourth side are located on opposite sides of the second folding plate. The third side is the side of the second side plate that is away from the cover plate, and the fourth side is the side of the second folding plate that is close to the cover plate. After the cover plate is closed, it can abut against the fourth side.

[0012] Based on the embodiments described above, the first and second folding plates extend from near the cover plate to the side of the second side plate opposite to the cover plate. This allows for easy assembly with the product and its protrusions while significantly increasing the protection range and effectively improving the protective effect of the protective structure. Furthermore, both the first and second folding plates support the cover plate. By covering and supporting the cover plate between the first and second side plates, the structural stability of the protective structure is improved, thereby further enhancing its protective effect.

[0013] In some examples, the first folding plate also includes a first folded edge, and the intersection of the second side, the first folded edge, and the cover plate is rounded. The second folding plate also includes a second folded edge, and the intersection of the fourth side, the second folded edge, and the cover plate is rounded.

[0014] Based on the above embodiments of this application, the rounded corners facilitate the bending of the first folding plate relative to the second side plate and the cover plate, and also facilitate the bending of the second folding plate relative to the second side plate and the cover plate. This prevents tearing at the intersection of the first folding plate, the second side plate and the cover plate during the folding and forming process of the protective structure. It also facilitates the forming of the protective structure and helps to improve the structural stability of the protective groove.

[0015] In some examples, the cover plate includes a main cover portion and a plug portion. The main cover portion is connected to the side of the second side plate, and the plug portion is located on the side of the main cover portion away from the second side plate. The plug portion can be bent relative to the main cover portion. The main cover portion is disposed between the first side plate and the second side plate, and the plug portion is inserted between the first side plate and the second side plate, and the plug portion can abut against the first side plate.

[0016] Based on the above embodiments of this application, the cover plate is disposed between the first side plate and the second side plate through the main cover portion, and can cooperate with the first folding plate, the second folding plate and the first side plate to form a protective groove, so that the protective groove has multiple protective functions.

[0017] In some examples, the first and second support edges are spaced apart from the first side plate, and the insertion part can be inserted between the first support edge and the first side plate, and between the second support edge and the first side plate. Alternatively, both the first and second support edges abut against the first side plate, the first support edge is provided with a first insertion groove, and the second support edge is provided with a second insertion groove, and the insertion part can be inserted into the first insertion groove and the second insertion groove.

[0018] Based on the above embodiments of this application, both of the above configurations can improve the insertion stability of the insertion part while ensuring that the first folding plate and the second folding plate are stably supported between the first side plate and the second side plate, thereby helping to ensure the reliability and stability of the protective structure.

[0019] In some examples, the first side plate, the second side plate, the third side plate, the cover plate, and the first folding plate enclose a first buffer cavity. The first side plate, the second side plate, the fourth side plate, the cover plate, and the second folding plate enclose a second buffer cavity, with the first and second buffer cavities located on opposite sides of the protective groove.

[0020] Based on the above embodiments of this application, the first buffer cavity and the second buffer cavity are arranged opposite to each other on both sides of the protective groove, which can play a certain buffering role on both sides of the protective groove, preventing the impact force from acting directly on the protective groove or the product, thereby effectively improving the protective effect of the protective structure.

[0021] In some examples, the size of the protective groove is greater than or equal to the size of the protrusion.

[0022] Based on the above embodiments of this application, the dimensions of the protective groove mainly include the length, width and depth of the protective groove. Similarly, the dimensions of the product protrusion mainly include the length, width and height. The dimensions of the protective groove are greater than or equal to the dimensions of the product, which means that the protective groove has a margin relative to the product protrusion. This can form a buffer space between the protective groove and the protrusion, further reducing the impact of the impact force on the protrusion and improving the protective effect.

[0023] In some examples, the protective structure also includes a fifth side plate located on the side of the second side plate closest to the fourth side plate, and the fifth side plate at least partially overlaps with the fourth side plate and is adhered to the fourth side plate.

[0024] Based on the embodiments described above, the fifth side plate is provided for fixed connection with the fourth side plate, thereby enabling the protective structure to maintain its shape after bending and forming. Furthermore, the fifth side plate and the fourth side plate are fixedly connected by adhesive bonding, which is simple in connection and easy to operate.

[0025] Secondly, embodiments of this application also provide a packaging structure for a circuit breaker, including a packaging box, a housing, an additional module, and the aforementioned protective structure. The housing includes a mounting surface, the additional module is disposed on the mounting surface and protrudes from the mounting surface, and the protective groove of the protective structure corresponds to the additional module. The housing, the additional module, and the protective structure are all disposed inside the packaging box.

[0026] Based on the above embodiments of this application, the above-mentioned protective structure can provide protection for the circuit breaker in the packaging box, prevent the additional modules installed on the surface of the circuit breaker housing from being damaged by bumps or impacts, and effectively improve the structural safety of the circuit breaker during transportation.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0042] Existing molded case circuit breakers are usually equipped with additional modules, which can provide corresponding auxiliary functions for the circuit breaker. The additional modules are usually installed on the plastic shell of the molded case circuit breaker and protrude from the side wall of the plastic shell. This configuration makes the molded case circuit breaker risky during transportation, that is, the additional modules are easily damaged or detached by bumps, which affects the normal use of the molded case circuit breaker.

[0043] Based on this, the embodiments of this application provide a protective structure and a packaging structure for circuit breakers, which can improve the protection effect of circuit breaker products and reduce the risk of damage to circuit breaker products caused by impacts.

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0045] Please refer to Figures 1 to 4 This embodiment provides a protective structure 1, which is formed by folding cardboard through preset creases. The product 2 includes a protrusion 21 that protrudes from the surface of the product 2. The protective structure 1 includes a first side plate 11, a second side plate 12, a third side plate 13, a fourth side plate 14, and a cover plate 16. The first side plate 11 and the second side plate 12 are arranged opposite to each other, and the third side plate 13 and the fourth side plate 14 are arranged opposite to each other.

[0046] The second side plate 12 includes a first folding plate 121 and a second folding plate 122 spaced apart. Both the first folding plate 121 and the second folding plate 122 fold towards the first side plate 11, and the first folding plate 121 and the second folding plate 122 are arranged opposite to each other. A cover plate 16 is disposed on the side of the second side plate 12, and the cover plate 16 can cover the space between the first side plate 11 and the second side plate 12. The first folding plate 121, the second folding plate 122, the cover plate 16, and the first side plate 11 together form a protective groove 17, which is adapted to the protrusion 21.

[0047] The protective structure 1 is made of folded cardboard. Cardboard has a certain strength and toughness, can withstand a certain amount of pressure and impact, and is simple and inexpensive to manufacture. At the same time, this molding method has strong adaptability and can be adapted to protrusions 21 of different shapes and sizes on product 2, providing effective protection for the protrusions 21 of product 2.

[0048] The protective structure 1 consists of a first side plate 11, a second side plate 12, a third side plate 13, a fourth side plate 14, and a cover plate 16. When the protective structure 1 is in the unfolded state, the first side plate 11, the third side plate 13, the second side plate 12, and the fourth side plate 14 are connected in sequence, and the cover plate 16 is connected to the second side plate 12. When the protective structure 1 is folded, the first side plate 11 and the second side plate 12 are positioned opposite each other, the third side plate 13 and the fourth side plate 14 are positioned opposite each other, and the cover plate 16 covers the space between the first side plate 11 and the second side plate 12, thus forming a cavity with an internal space.

[0049] In this embodiment, the second side plate 12 is close to or abuts against the product 2 on the side opposite to the first side plate 11, and the size of the second side plate 12 is greater than or equal to the size of the product 2. In this way, the cavity with internal space formed by the enclosure can play a role in isolating and buffering the product 2. Compared with a single partition, this embodiment has a stronger protective effect on the product 2.

[0050] Furthermore, the first folding plate 121 and the second folding plate 122 are spaced apart at the middle position of the second side plate 12, and the first folding plate 121 and the second folding plate 122 are folded relative to the second side plate 12 towards the direction of the first side plate 11, and the folded first folding plate 121 and the second folding plate 122 are opposite to each other. In this way, the first folding plate 121, the second folding plate 122 and the first side plate 11 can form a partial protective groove 17, which can fit the protrusion 21 of the product 2 to protect the protrusion 21.

[0051] The cover plate 16 is disposed on the side of the second side plate 12, that is, on the side of the second side plate 12 adjacent to the third side plate 13 and the fourth side plate 14. The cover plate 16 can cover one side opening of the internal space formed by the first side plate 11, the second side plate 12, the third side plate 13, and the fourth side plate 14. On the one hand, it can form a protective groove 17 together with the first folding plate 121, the second folding plate 122, and the first side plate 11, thereby improving the protective effect on the protrusion 21. On the other hand, it can be supported between the first side plate 11 and the second side plate 12, thereby improving the structural stability of the protective structure 1 and preventing the protective structure 1 from easily deforming.

[0052] Based on the above embodiments of this application, by providing a first folding plate 121, a second folding plate 122, and a cover plate 16 on the protective structure 1 formed by the first side plate 11, the second side plate 12, the third side plate 13, and the fourth side plate 14, a protective groove 17 is formed on the protective structure 1. The protective groove 17 can accommodate the protrusion 21 on the product 2, so that the protective structure 1 can not only protect the main body of the product 2, but also protect the protrusion 21 on the product 2 separately, effectively improving the protective effect of the protective structure 1 on the product 2, reducing the risk of damage caused by collisions to the protrusion 21, and facilitating the safe transportation of the product 2.

[0053] It should be noted that the protective structure 1 provided in this embodiment can be applied to the additional modules provided on the surface of the molded case circuit breaker 3, and can also be applied to the protrusions 21 provided on the surface of other products 2. Furthermore, for different products 2, cardboard of different thicknesses and materials can be selected according to the weight, size, and protection requirements of the product 2. For example, for heavier products 2, cardboard with greater thickness and higher strength can be selected. For products 2 requiring moisture protection, cardboard with moisture-proof properties can be selected.

[0054] Of course, the protective structure 1 can also be made of materials such as plastic, wood, metal or rubber. The protective structure 1 made of the above materials can provide relatively stable protection.

[0055] In some examples, refer to Figure 5 and Figure 6 The first folding plate 121 includes a first support edge 1211, which abuts against the side of the first side plate 11 near the second side plate 12. The second folding plate 122 includes a second support edge 1221, which abuts against the side of the first side plate 11 near the second side plate 12.

[0056] Based on the above embodiments of this application, the first support edge 1211 abutting against the first side plate 11 means that the first folding plate 121 is supported between the first side plate 11 and the second side plate 12, and the second support edge 1221 abutting against the first side plate 11 means that the second folding plate 122 is also supported between the first side plate 11 and the second side plate 12. In this way, the first folding plate 121 and the second folding plate 122 can stably support the first side plate 11 and the second side plate 12, prevent the protective structure 1 from deforming, thereby improving the structural stability of the protective groove 17 and ensuring that the protective groove 17 can provide reliable protection.

[0057] In some examples, refer to Figure 5 and Figure 6The first folding plate 121 also includes a first side 1212 and a second side 1213. The first side 1212 and the second side 1213 are located on opposite sides of the first folding plate 121. The first side 1212 is the side of the second side plate 12 that is away from the cover plate 16. The second side 1213 is the side of the first folding plate 121 that is close to the cover plate 16. After the cover plate 16 is closed, it can abut against the second side 1213.

[0058] The second folding plate 122 also includes a third side 1222 and a fourth side 1223. The third side 1222 and the fourth side 1223 are located on opposite sides of the second folding plate 122. The third side 1222 is the side of the second side plate 12 away from the cover plate 16, and the fourth side 1223 is the side of the second folding plate 122 close to the cover plate 16. After the cover plate 16 is closed, it can abut against the fourth side 1223.

[0059] The first side 1212 of the first folding plate 121 is the side of the second side plate 12 facing away from the cover plate 16, and the second side 1213 is close to the cover plate 16, meaning that the first folding plate 121 extends from the position close to the cover plate 16 to the side of the second side plate 12 facing away from the cover plate 16. The third side 1222 of the second folding plate 122 is the side of the second side plate 12 facing away from the cover plate 16, and the fourth side 1223 is close to the cover plate 16, meaning that the second folding plate 122 also extends from the position close to the cover plate 16 to the side of the second side plate 12 facing away from the cover plate 16.

[0060] The protective groove 17 formed in this way connects from the position near the cover plate 16 to the side of the second side plate 12 away from the cover plate 16. On the one hand, it can greatly increase the protective range of the protective groove 17, thereby enhancing the protective effect of the protective structure 1. On the other hand, it facilitates the installation of the protective structure 1 with the protrusion 21 of the product 2. It can be installed simply by entering the protective groove 17 from the side of the second side plate 12 away from the cover plate 16 and moving it in the direction of the cover plate 16.

[0061] In addition, the cover plate 16 can abut against the second side 1213 of the first folding plate 121 and the fourth side 1223 of the second folding plate 122. In this way, the first folding plate 121 and the second folding plate 122 can support the cover plate 16, so that the cover plate 16 can maintain a stable closed state between the first side plate 11 and the second side plate 12. Thus, the cover plate 16 can be stably supported between the first side plate 11 and the second side plate 12, which is beneficial to improving the structural stability of the protective structure 1.

[0062] Based on the embodiments described above, the first folding plate 121 and the second folding plate 122 extend from a position near the cover plate 16 to the side of the second side plate 12 opposite to the cover plate 16. This allows for easy assembly with the product 2 and its protrusion 21 while significantly increasing the protection range and effectively improving the protective effect of the protective structure 1. Furthermore, both the first folding plate 121 and the second folding plate 122 support the cover plate 16. By covering and supporting the cover plate 16 between the first side plate 11 and the second side plate 12, the structural stability of the protective structure 1 can be improved, thereby further enhancing its protective effect.

[0063] In some examples, refer to Figure 4 The first folding plate 121 also includes a first folding edge 1214, and the intersection of the second side 1213, the first folding edge 1214 and the cover plate 16 is rounded. The second folding plate 122 also includes a second folding edge 1224, and the intersection of the fourth side 1223, the second folding edge 1224 and the cover plate 16 is rounded.

[0064] Based on the above embodiments of this application, the rounded corners facilitate the bending of the first folding plate 121 relative to the second side plate 12 and the cover plate 16, and also facilitate the bending of the second folding plate 122 relative to the second side plate 12 and the cover plate 16. This prevents tearing at the intersection of the first folding plate 121, the second side plate 12 and the cover plate 16 during the folding and forming process of the protective structure 1, and also prevents tearing at the intersection of the second folding plate 122, the second side plate 12 and the cover plate 16. This facilitates the forming of the protective structure 1 and also helps to improve the structural stability of the protective groove 17.

[0065] In some examples, refer to Figures 2 to 4 The cover plate 16 includes a main cover portion 161 and a plug portion 162. The main cover portion 161 is connected to the side of the second side plate 12. The plug portion 162 is located on the side of the main cover portion 161 away from the second side plate 12. The plug portion 162 can be bent relative to the main cover portion 161. The main cover portion 161 covers the first side plate 11 and the second side plate 12. The plug portion 162 is inserted between the first side plate 11 and the second side plate 12, and the plug portion 162 can abut against the first side plate 11.

[0066] Based on the above embodiments of this application, the cover plate 16 is disposed between the first side plate 11 and the second side plate 12 through the main cover portion 161, and can cooperate with the first folding plate 121, the second folding plate 122 and the first side plate 11 to form a protective groove 17, so that the protective groove 17 has multiple protective functions.

[0067] Meanwhile, the cover plate 16 is inserted into the space between the first side plate 11 and the second side plate 12 through the insertion part 162, and the insertion part 162 abuts against the first side plate 11. In this way, the insertion part 162 can reduce the risk of the cover plate 16 being easily opened by using the friction between it and the first side plate 11, so that the cover plate 16 is stably abutted against the first side plate 11, and the main cover part 161 is used to support it between the first side plate 11 and the second side plate 12, ensuring the structural stability of the protective groove 17 and improving the reliability of the protective structure 1.

[0068] Specifically, the length of the cover plate 16 can be less than or equal to the length of the second side plate 12. When the length of the cover plate 16 is less than the length of the second side plate 12, it means that the cover plate 16 can only cover part of the space between the first side plate 11 and the second side plate 12, which can also achieve the above-mentioned function. In one case, the length of the cover plate 16 is the same as the distance between the first folding plate 121 and the second folding plate 122, that is, the cover plate 16 exactly covers the space between the first side plate 11 and the second side plate 12 and corresponds to the space between the first folding plate 121 and the second folding plate 122. This can both form a protective groove 17 and provide support for the cover plate 16, while also saving material usage.

[0069] When the length of the cover plate 16 is equal to the length of the second side plate 12, the cover plate 16 can completely cover the space between the first side plate 11 and the second side plate 12 to provide reliable protection and support.

[0070] The insertion part 162 can be inserted into the first side plate 11 and the second side plate 12 in the following specific ways:

[0071] In some examples, refer to Figure 4 The first support edge 1211 and the second support edge 1221 are spaced apart from the first side plate 11, and the insertion part 162 can be inserted between the first support edge 1211 and the first side plate 11 and between the second support edge 1221 and the first side plate 11.

[0072] Specifically, the first support edge 1211 and the second support edge 1221 are spaced apart from the first side plate 11, that is, neither the first folding plate 121 nor the second folding plate 122 is directly supported on the first side plate 11. The distance between the first support edge 1211 and the second support edge 1221 and the first side plate 11 corresponds to the thickness of the insertion part 162. After the insertion part 162 is inserted between the first side plate 11 and the second side plate 12, it can be located in the interval between the first support edge 1211 and the second support edge 1221 and the first side plate 11. In this way, the insertion part 162 can be clamped between the first side plate 11 and the first support edge 1211 and between the first side plate 11 and the second support edge 1221, which can stabilize the closing of the cover plate 16 and also play a corresponding supporting role.

[0073] In some examples, refer to Figure 5 and Figure 6 The first support edge 1211 and the second support edge 1221 both abut against the first side plate 11. The first support edge 1211 is provided with a first insertion groove 1215, and the second support edge 1221 is provided with a second insertion groove 1225. The insertion part 162 can be inserted into the first insertion groove 1215 and the second insertion groove 1225.

[0074] By providing a first insertion groove 1215 on the first support edge 1211 near the cover plate 16 and a second insertion groove 1225 on the second support edge 1221 near the cover plate 16, the insertion part 162 is easily inserted and the insertion is kept stable without affecting the support provided by the first folding plate 121 and the second folding plate 122.

[0075] Based on the above embodiments of this application, both of the above configurations can improve the insertion stability of the insertion part 162 while ensuring that the first folding plate 121 and the second folding plate 122 are stably supported between the first side plate 11 and the second side plate 12, thereby both are conducive to ensuring the reliability and stability of the protective structure 1.

[0076] In another embodiment, the first side plate 11 may also be provided with a tongue, and the cover plate 16 may be provided with a plug hole. After the plug part 162 on the cover plate 16 is inserted between the first side plate 11 and the second side plate 12, the tongue on the first side plate 11 can be inserted into the plug hole, which can further ensure that the cover plate 16 remains stable after it is closed.

[0077] In some examples, refer to Figure 4 The first side plate 11, the second side plate 12, the third side plate 13, the cover plate 16, and the first folding plate 121 enclose to form a first buffer cavity 18. The first side plate 11, the second side plate 12, the fourth side plate 14, the cover plate 16, and the second folding plate 122 enclose to form a second buffer cavity 19. The first buffer cavity 18 and the second buffer cavity 19 are located on opposite sides of the protective groove 17.

[0078] Based on the above embodiments of this application, the first buffer cavity 18 and the second buffer cavity 19 are disposed opposite to each other on both sides of the protective groove 17, which can play a certain buffering role on both sides of the protective groove 17, preventing the impact force from acting directly on the protective groove 17 or the product 2, thereby effectively improving the protective effect of the protective structure 1.

[0079] In some examples, the size of the protective groove 17 is greater than or equal to the size of the protrusion 21.

[0080] Based on the above embodiments of this application, the dimensions of the protective groove 17 mainly include the length, width and depth of the protective groove 17. Similarly, the dimensions of the protrusion 21 of the product 2 mainly include the length, width and height. The dimensions of the protective groove 17 are greater than or equal to the dimensions of the product 2, which means that the protective groove 17 has a margin relative to the protrusion 21 of the product 2. This can form a buffer space between the protective groove 17 and the protrusion 21, further reducing the impact of the impact force on the protrusion 21 and improving the protective effect.

[0081] In some examples, refer to Figure 3 and Figure 4 The protective structure 1 also includes a fifth side plate 15, which is located on the side of the second side plate 12 that is close to the fourth side plate 14, and the fifth side plate 15 at least partially overlaps with the fourth side plate 14 and is bonded to the fourth side plate 14.

[0082] Based on the above embodiments of this application, the fifth side plate 15 is provided for fixed connection with the fourth side plate 14, thereby enabling the protective structure 1 to maintain its shape after bending and forming. Furthermore, the fifth side plate 15 and the fourth side plate 14 are fixedly connected by adhesive bonding, which has the advantages of simple connection method and easy operation.

[0083] Specifically, in the unfolded state, the fifth side plate 15 is located on the side of the second side plate 12 away from the third side plate 13. After folding and forming, the fifth side plate 15 and the fourth side plate 14 at least partially overlap. The fifth side plate 15 and the fourth side plate 14 are then connected by an adhesive connection, which is conducive to the rapid forming of the protective structure 1 and maintaining its stability.

[0084] Secondly, referring to Figure 7 This application embodiment also provides a packaging structure for a circuit breaker 3, including a packaging box 4, a housing, an additional module, and the aforementioned protective structure 1. The housing includes a mounting surface, the additional module is disposed on the mounting surface and protrudes from the mounting surface, and the protective groove 17 of the protective structure 1 corresponds to the additional module. The housing, the additional module, and the protective structure 1 are all disposed inside the packaging box 4.

[0085] Based on the above embodiments of this application, the above-mentioned protective structure 1 can provide protection for the circuit breaker 3 in the packaging box 4, preventing the additional modules provided on the surface of the circuit breaker 3 housing from being damaged by bumps or impacts, and effectively improving the structural safety of the circuit breaker 3 during transportation.

[0086] The packaging box 4 is used to package the circuit breaker 3. The packaging box 4 is typically a regular shape, such as a cube or cuboid. The additional modules of the circuit breaker 3 are located on the surface of the circuit breaker 3 housing. These additional modules protrude from the housing surface, making them susceptible to impact and damage. The protective structure 1 acts as a liner inside the packaging box 4, protecting the circuit breaker 3 within it. The protective groove 17 on the protective structure 1 separately protects the protruding additional modules, thus preventing direct impact forces from acting on them and improving the structural safety of the circuit breaker 3.

[0087] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
