Description

Technical Field

[0001] This application relates to the field of circuit breaker technology, and more particularly to a circuit breaker cover and a circuit breaker. Background Technology

[0002] Molded case circuit breakers include a center cover, which is injection molded. During the production of the center cover, an information module is typically added to the mold, so that after injection molding, the center cover displays identification information corresponding to that module, such as a logo. This identification information is integrally molded with the center cover.

[0003] In related technologies, the identification information required by customers often varies. To meet customer needs, it is necessary to replace the information module on the middle cover mold and then re-inject the middle cover to reflect the required identification information. However, changing the identification information is inconvenient and affects the production efficiency of the middle cover. Utility Model Content

[0004] This application provides a circuit breaker cover and a circuit breaker to improve the ease of replacing the marking information on the cover and ensure the production efficiency of the cover.

[0005] In a first aspect, this application provides a circuit breaker cover, including a cover body and an information carrier. The information carrier has an information marking surface on which preset information is marked. A first connecting portion is provided on the side of the information carrier facing away from the information marking surface, and a second connecting portion matching the first connecting portion is provided on the cover body. The first connecting portion and the second connecting portion cooperate to connect the information carrier to the cover body in a detachable manner.

[0006] The circuit breaker cover provided in this application comprises a cover body and an information carrier component. A first connecting portion is provided on the information carrier component, and a second connecting portion is provided on the cover body. The information carrier component and the cover body are detachably connected through the cooperation of the first and second connecting portions. In other words, the cover body and the information carrier component are two independent parts, manufactured separately, and detachably connected. Since the information carrier component has preset information marked on its information labeling surface, with one information carrier component corresponding to one preset labeling information, installing the information carrier component onto the cover body via the first and second connecting portions forms a circuit breaker cover displaying the preset labeling information. Therefore, if the labeling information needs to be changed, only the information carrier component on the cover body needs to be replaced to display the required labeling information on the cover body, thereby improving the ease of changing the labeling information on the circuit breaker cover.

[0007] Furthermore, since the cover body and the information carrier are manufactured separately, the replacement of the information carrier will not affect the production of the cover body. In other words, the replacement of the marking information on the cover body will not affect the production of the cover body, thus ensuring the production efficiency of the circuit breaker cover.

[0008] In one possible design, the first connecting part includes a latching protrusion, and the second connecting part includes a latching groove into which the latching protrusion can be engaged.

[0009] The above solution involves setting a protruding tab on the information carrier and a slot on the cover body, allowing the information carrier and the cover body to be detachably connected through the cooperation of the protruding tab and the slot. The structure is simple, easy to manufacture, the connection is reliable and stable, and the installation and disassembly are convenient, making it easier to replace the information carrier on the cover body.

[0010] In one possible design, the latch includes a connecting rod and a latching tongue. One end of the connecting rod is fixed to the side of the information carrier facing away from the information label, and the other end of the connecting rod extends in a direction away from the information carrier. The latching tongue is disposed on the other end of the connecting rod and intersects with the connecting rod; the latching tongue engages with the latching groove.

[0011] The above solution incorporates a connecting rod and a latch, with the latch engaging with the slot. The latch is mounted on the information carrier via the connecting rod. This improves the latch's flexibility and deformation performance, facilitating the engagement between the latch and the slot, and enhancing the stability and reliability of the engagement. This further improves the ease and reliability of installation between the information carrier and the cover body. Furthermore, it provides more installation space for the information carrier on the cover body, facilitating its assembly.

[0012] In one possible design, a first limiting part is provided on the side of the information carrier that is away from the information label surface, and a second limiting part adapted to the first limiting part is provided on the cover body. When the first connecting part and the second connecting part are connected, the first limiting part and the second limiting part cooperate to limit the information carrier.

[0013] With the above solution, a first limiting part is set on the information carrier and a second limiting part is set on the cover body. When the information carrier is installed on the cover body through the cooperation of the first connecting part and the second connecting part, the first limiting part and the second limiting part can cooperate with each other, thereby improving the connection strength between the first connecting part and the second connecting part, thus limiting the information carrier, improving the connection stability of the information carrier on the cover body, and making the overall integrity of the circuit breaker cover better.

[0014] In one possible design, the first limiting part includes a limiting groove, and the second limiting part includes a limiting post that can extend into the limiting groove.

[0015] The above-described design incorporates a limiting groove on the information carrier and a limiting post on the cover body, resulting in a simple structure that is easy to manufacture. During assembly, the information carrier is installed on the cover body, and the limiting post extends into the limiting groove. The limiting groove acts as a stop and limit for the limiting post, preventing radial displacement of the post relative to the groove. Similarly, the limiting post also acts as a stop and limit for the limiting groove, preventing displacement of the groove. This effective limiting of the information carrier ensures a more reliable and stable installation of the information carrier on the cover body.

[0016] In one possible design, a limiting ring is provided on the side of the information carrier that is away from the information label surface, and the inner cavity of the limiting ring is formed as a limiting groove.

[0017] The above solution involves setting a limiting ring on the side of the information carrier component facing away from the information label surface. The inner cavity of the limiting ring forms a limiting groove, and a limiting post extends into the limiting ring, thus limiting the movement of the information carrier component. This structure is simple and easy to manufacture. Furthermore, the limiting ring reinforces the structure of the information carrier component, thereby improving its structural strength and extending its service life.

[0018] In one possible design, the limiting groove is a strip groove, and there are at least two limiting posts. At least two limiting posts are spaced apart on the cover body along the length of the strip groove. All limiting posts extend into the strip groove, and the two outermost limiting posts abut against the groove wall.

[0019] The above solution involves designing the limiting groove on the information carrier component as a strip groove, and setting multiple limiting posts on the cover body. These posts are spaced apart along the length of the strip groove. During assembly, all limiting posts extend into the strip groove, with the two outermost posts abutting against the groove wall. This design offers several advantages: firstly, multiple limiting posts cooperate with the same limiting groove for positioning, resulting in a simple structure, high matching degree, and good limiting effect. Secondly, it reduces the manufacturing precision required for the limiting posts and groove to some extent, thus improving the production efficiency of the circuit breaker cover.

[0020] In one possible design, the cover body is provided with a mounting groove for installing information carriers, a limiting post is provided at the bottom of the mounting groove, and a second connecting part is provided inside the mounting groove.

[0021] The above solution involves setting an installation groove on the cover body, with both the limiting post and the second connecting part placed within it. On one hand, the installation groove provides support for the information carrier, enhancing the stability and reliability of the connection between the information carrier and the cover body. On the other hand, since both the limiting post and the second connecting part are located within the installation groove, the groove protects them, helping to extend their service life.

[0022] In one possible design, the cover body has a first boss and a second boss located on one side of the first boss. The first boss has a handle groove for a circuit breaker, and the second boss has a mounting groove for installing an information carrier. A second connecting part is disposed in the mounting groove. When the second connecting part and the first connecting part are connected, the information label face is placed at the opening of the mounting groove and is flush with the side of the first boss that is away from the cover body.

[0023] With the above solution, a handle groove for installing a circuit breaker handle is provided on the first protrusion of the cover body, and a second protrusion is also provided on the cover body, located to one side of the first protrusion. A mounting groove is provided on the second protrusion, and a second connecting part is disposed within the mounting groove. The first and second connecting parts cooperate to connect, and when the information carrier is installed on the mounting groove, the information label face is placed at the opening of the mounting groove. This arrangement, through the mounting groove, provides support for the information carrier, thus improving the connection stability and reliability of the information carrier on the cover body.

[0024] In one possible design, at least a portion of the circumferential surface of the first boss has a first chamfer on the side opposite to the cover body, and at least a portion of the circumferential surface of the information label has a second chamfer. The second chamfer has the same structure as the first chamfer, and the information label is the same color as the first boss.

[0025] The above solution makes the structure of the first chamfer on the first protrusion the same as that of the second chamfer on the information label surface, and makes the colors of the information label surface and the first protrusion the same. This improves the consistency and integrity of the information label surface and the first protrusion, thereby further enhancing the integrated visual effect and aesthetics.

[0026] In one possible design, the second boss is positioned close to the first boss so that the information label surface is close to the first boss, and the first chamfer and the second chamfer are aligned at the junction of the information-carrying surface and the first boss.

[0027] By using the above scheme, the second protrusion is positioned close to the first protrusion, that is, the second protrusion is positioned adjacent to the first protrusion. This arrangement ensures that after the information carrier is connected to the cover body, the information label surface and the side of the first protrusion facing away from the cover body are not only flush but also adjacent to each other. Furthermore, the first chamfer and the second chamfer are aligned at their joint, thereby improving the consistency and integrity of the information label surface and the first protrusion, thus further enhancing the integrated visual effect and aesthetics.

[0028] In one possible design, there are at least two first connecting parts, which are spaced apart on the information carrier, and at least two second connecting parts, with one first connecting part cooperating with one second connecting part for connection.

[0029] Through the above scheme, multiple first connecting parts are spaced apart on the information carrier and multiple second connecting parts are spaced apart on the cover body. The first connecting parts and the second connecting parts are connected one-to-one. In this way, the information carrier and the cover body are connected together by the cooperation of multiple sets of first connecting parts and second connecting parts. That is to say, there are multiple sets of connecting parts between the information carrier and the cover body, which improves the connection strength and reliability between the information carrier and the cover body.

[0030] Secondly, this application provides a circuit breaker, including the circuit breaker cover as described above.

[0031] The beneficial effects of the circuit breakers provided in the second aspect and the various possible designs of the second aspect can be found in the first aspect and the various possible implementations of the first aspect, and will not be repeated here. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims and drawings of this application are intended to cover non-exclusive inclusion.

[0044] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists, A and B exist simultaneously, or B exists. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0046] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the circuit breaker cover and circuit breaker of this application. For example, in the description of this application, the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] Molded case circuit breakers include a center cover, which is injection molded. During the production of the center cover, an information module is typically added to the mold, so that after injection molding, the center cover displays identification information corresponding to that module, such as a logo. This identification information is integrally molded with the center cover.

[0051] In related technologies, the identification information required by customers often varies. To meet customer needs, it is necessary to replace the information module on the middle cover mold and then re-inject the middle cover to reflect the required identification information. However, changing the identification information is inconvenient and affects the production efficiency of the middle cover.

[0052] Based on this, this embodiment provides a circuit breaker cover and a circuit breaker. The circuit breaker cover includes a cover body and an information carrier. The information carrier has an information marking surface, on which preset information is marked. Each information carrier corresponds to one preset marking information. By making the cover body and the information carrier detachably connected—that is, the cover body and the information carrier are manufactured separately and can be detachably connected—if you want to change the marking information, you only need to replace the information carrier on the cover body to display the required marking information on the cover body, thereby improving the convenience of changing the marking information on the circuit breaker cover.

[0053] The following detailed description, with reference to the accompanying drawings and specific embodiments, illustrates a circuit breaker cover and circuit breaker provided in this embodiment.

[0054] This embodiment provides a circuit breaker, which includes a circuit breaker cover and a base (not shown).

[0055] The circuit breaker cover and base are connected together and together enclose a mounting cavity. The mounting cavity is used to install other components of the circuit breaker, such as the contact system (not shown), arc extinguishing device (not shown), operating mechanism (not shown), and tripping device (not shown).

[0056] The circuit breaker cover and base can be connected together using bolts, clips, or other methods, making installation and disassembly convenient and easy to replace, thus helping to save on replacement costs. Alternatively, the circuit breaker cover and base can be bonded together with structural adhesive, resulting in better overall integrity.

[0057] Circuit breaker covers and bases can be made of plastic, which is easy to manufacture and has good insulation properties.

[0058] refer to Figure 1 and Figure 2 As shown, this embodiment provides a circuit breaker cover, which includes a cover body 1 and an information carrier 2.

[0059] refer to Figures 2 to 5 As shown, the information carrier 2 has an information labeling surface 21 on which preset information is labeled. A first connecting part 3 is provided on the side of the information carrier 2 opposite to the information labeling surface 21, and a second connecting part 4 matching the first connecting part 3 is provided on the cover body 1. The first connecting part 3 and the second connecting part 4 are connected to each other to detachably connect the information carrier 2 to the cover body 1.

[0060] The information carrier 2 can display preset information, such as a logo or trademark (logotype, or simply logo). It can also display parameters such as the breaking capacity or current characteristics of the circuit breaker, or other information customized by the customer.

[0061] It should be noted that the preset information on the information label surface 21 is an integral structure with the information carrier 2 after it is made. In other words, the preset information on each information carrier 2 is fixed after it is made.

[0062] In practice, the preset information and the information carrier 2 can be integrally formed by means of molding, for example. After the information carrier 2 is made, it has the corresponding preset information engraved on it, which is convenient for mass production and has high production efficiency.

[0063] Of course, preset information can also be engraved on the information carrier 2 after the information carrier 2 is made, using methods such as laser or pad printing. The preset information has a high degree of precision.

[0064] The circuit breaker cover body 1 and the information carrier 2 provided in this application are two independent parts. That is to say, the cover body 1 and the information carrier 2 are manufactured separately, and the production of the information carrier 2 will not affect the production of the cover body 1.

[0065] refer to Figure 4 and Figure 5 As shown, since the information carrier 2 is provided with a first connecting part 3 and the cover body 1 is provided with a second connecting part 4, after the information carrier 2 and the cover body 1 are manufactured respectively, the information carrier 2 can be installed on the cover body 1 by the cooperation of the first connecting part 3 and the second connecting part 4, and assembled into a circuit breaker cover with preset information.

[0066] Since the information carrier 2 and the cover body 1 are detachably connected through the cooperation of the first connecting part 3 and the second connecting part 4, the information carrier 2 can be removed from the cover body 1 for replacement. This is based on the specific working conditions. If the preset information needs to be replaced, simply make the information carrier 2 with the preset information that meets the working conditions and install it on the cover body 1. Compared with the related technology, which involves replacing the information module on the cover body mold and then re-injecting the cover body to display the identification information required by the customer, this method improves the convenience of replacing the identification information and does not affect the production efficiency of the cover body 1.

[0067] In practice, the information carrier 2 can be injection molded from nylon (Polyamide, abbreviated as PA) or polycarbonate (Polycarbonate, abbreviated as PC), which has good etching performance.

[0068] The cover body 1 can be injection molded from dimethyl carbonate (DMC) or polycarbonate (PC), which has good flame retardancy.

[0069] It should be noted that the information carrier 2 and the cover body 1 can be made of the same material or different materials.

[0070] In a practical implementation, the first connecting part 3 and the information carrier 2 can be integrally molded, resulting in good overall integrity and high structural strength. Alternatively, in other implementations, the first connecting part 3 and the information carrier 2 can be attached together using structural adhesive, bolts, or other fasteners.

[0071] Similarly, the second connecting part 4 and the cover body 1 can be integrally formed, or they can be installed together by structural adhesive, bolts or other fasteners.

[0072] The circuit breaker cover provided in this embodiment includes a cover body 1 and an information carrier 2. A first connecting part 3 is provided on the information carrier 2, and a second connecting part 4 is provided on the cover body 1. The information carrier 2 and the cover body 1 are detachably connected through the cooperation of the first connecting part 3 and the second connecting part 4. That is, the cover body 1 and the information carrier 2 are two independent parts, manufactured separately, and detachably connected. Since the information marking surface 21 of the information carrier 2 is marked with preset information, one information carrier 2 corresponds to one preset marking information. Therefore, by installing the information carrier 2 onto the cover body 1 through the first connecting part 3 and the second connecting part 4, a circuit breaker cover displaying the preset marking information can be formed. Based on this, if the marking information needs to be changed, only the information carrier 2 on the cover body 1 needs to be replaced to display the required marking information on the cover body 1, thereby improving the convenience of changing the marking information on the circuit breaker cover.

[0073] Furthermore, since the cover body 1 and the information carrier 2 are manufactured separately, the replacement of the information carrier 2 will not affect the production of the cover body 1. In other words, the replacement of the marking information on the cover body 1 will not affect the production of the cover body 1, thereby ensuring the production efficiency of the circuit breaker cover.

[0074] refer to Figure 4 and Figure 5 As shown, in some embodiments, the first connecting part 3 includes a latching protrusion, and the second connecting part 4 includes a latching groove into which the latching protrusion can be latched, so that the information carrier 2 is latched and connected to the cover body 1 through the cooperation of the latching protrusion and the latching groove.

[0075] By setting a protrusion on the information carrier 2 and a slot on the cover body 1, the information carrier 2 and the cover body 1 can be detachably connected through the cooperation of the protrusion and the slot. The structure is simple, easy to manufacture, the connection is reliable and stable, and the installation and disassembly are convenient, making it easier to replace the information carrier 2 on the cover body 1.

[0076] In other embodiments, the first connecting portion on the information carrier may be, for example, a card slot, and the second connecting portion on the cover body may be, for example, a card protrusion extending into the card slot.

[0077] Of course, in other embodiments, the information carrier 2 can also be mounted on the cover body 1 by fasteners such as bolts.

[0078] refer to Figures 5 to 7 As shown, in some embodiments, the latch includes a connecting rod 31 and a latch 32. One end of the connecting rod 31 is fixed to the side of the information carrier 2 facing away from the information identification surface 21, and the other end of the connecting rod 31 extends in a direction away from the information carrier 2. The latch 32 is disposed on the other end of the connecting rod 31 and intersects with the connecting rod 31; the latch 32 engages with the latch groove.

[0079] The latching mechanism includes a connecting rod 31 and a latching tongue 32. The latching tongue 32 engages with the latching groove. Mounting the latching tongue 32 onto the information carrier 2 via the connecting rod 31 enhances the flexibility and deformation performance of the latching tongue 32, facilitating its engagement with the latching groove and improving the stability and reliability of the engagement. This further improves the ease and reliability of installation between the information carrier 2 and the cover body 1. Furthermore, it provides greater installation space for the information carrier 2 on the cover body 1, facilitating its assembly.

[0080] For example, refer to Figures 5 to 7 As shown, the latch 32 can be perpendicular to the connecting rod 31, and the latch 32 and the connecting rod 31 form an L-shaped structure.

[0081] refer to Figure 2 , Figures 5 to 9 As shown, in some embodiments, there are at least two first connecting parts 3, which are spaced apart on the information carrier 2, and at least two second connecting parts 4, with one first connecting part 3 and one second connecting part 4 cooperating and connecting.

[0082] By providing multiple first connecting parts 3 at intervals on the information carrier 2 and multiple second connecting parts 4 at intervals on the cover body 1, with the first connecting parts 3 and the second connecting parts 4 connected in a one-to-one correspondence, the information carrier 2 and the cover body 1 are connected together through the cooperation of multiple sets of first connecting parts 3 and second connecting parts 4. In other words, there are multiple sets of connecting parts between the information carrier 2 and the cover body 1, which improves the connection strength and reliability between the information carrier 2 and the cover body 1.

[0083] For example, refer to Figure 4 and Figure 5 As shown, the information carrier 2 is provided with two protrusions, and the cover body 1 is provided with two slots. One protrusion corresponds to one slot. The information carrier 2 is detachably connected to the cover body 1 through the cooperation of the two protrusions and the two slots.

[0084] In practice, the two latches 32 can be extended in directions that are far apart from each other.

[0085] refer to Figure 4 and Figure 5 As shown, in some embodiments, a first limiting part 5 is provided on the side of the information carrier 2 that is away from the information label surface 21, and a second limiting part 6 that is adapted to the first limiting part 5 is provided on the cover body 1. When the first connecting part 3 and the second connecting part 4 are connected, the first limiting part 5 and the second limiting part 6 cooperate to limit the information carrier 2.

[0086] By setting a first limiting part 5 on the information carrier 2 and a second limiting part 6 on the cover body 1, when the information carrier 2 is installed on the cover body 1 through the cooperation of the first connecting part 3 and the second connecting part 4, the first limiting part 5 and the second limiting part 6 can cooperate with each other, thereby improving the connection strength between the first connecting part 3 and the second connecting part 4, thus limiting the information carrier 2, improving the connection stability of the information carrier 2 on the cover body 1, and making the overall integrity of the circuit breaker cover better.

[0087] refer to Figure 4 and Figure 5 As shown, in some embodiments, the first limiting part 5 includes a limiting groove, and the second limiting part 6 includes a limiting post that can extend into the limiting groove.

[0088] By setting a limiting groove on the information carrier 2 and a limiting post on the cover body 1, the structure is simple and easy to manufacture.

[0089] During assembly, the information carrier 2 is installed on the cover body 1, and the limiting post can be inserted into the limiting groove. The limiting groove acts as a stop and limit for the limiting post, preventing the limiting post from shifting radially relative to the limiting groove. Similarly, the limiting post also acts as a stop and limit for the limiting groove, preventing the limiting groove from shifting. The limiting effect on the information carrier 2 is good, thus making the installation of the information carrier 2 on the cover body 1 more reliable and stable.

[0090] In other embodiments, the first limiting part 5 on the information carrier 2 may be a limiting post, and the second limiting part 6 on the cover body 1 may be a limiting groove into which the limiting post extends.

[0091] refer to Figure 5 As shown, in some embodiments, a limiting ring 7 is provided on the side of the information carrier 2 facing away from the information identification surface 21, and the inner cavity of the limiting ring 7 is formed as a limiting groove.

[0092] By setting a limiting ring 7 on the side of the information carrier 2 opposite to the information label surface 21, and forming a limiting groove within the inner cavity of the limiting ring 7, with the limiting post extending into the limiting ring 7, the information carrier 2 can be limited. This structure is simple and easy to manufacture. Furthermore, the limiting ring 7 reinforces the structure of the information carrier 2, thereby improving its structural strength and helping to extend its service life.

[0093] During assembly, when the cam and slot engage, the limiting post on the cover body 1 extends into the limiting ring 7 on the information carrier 2. The outer wall of the limiting post and the inner wall of the limiting ring 7 are fitted with a clearance, thereby limiting the information carrier 2.

[0094] refer to Figures 4 to 9 As shown, in some embodiments, the limiting groove is a strip groove, and there are at least two limiting posts. At least two limiting posts are spaced apart on the cover body 1 along the length direction of the strip groove. All limiting posts extend into the strip groove, and the two outermost limiting posts abut against the groove wall of the strip groove.

[0095] The limiting groove on the information carrier 2 is set as a strip groove, and multiple limiting posts are set on the cover body 1. The multiple limiting posts are spaced apart along the length of the strip groove on the cover body 1. In actual assembly, all the limiting posts extend into the strip groove, and the two outermost limiting posts abut against the groove wall. This setting has two advantages: firstly, multiple limiting posts cooperate with the same limiting groove for limiting, the structure is simple, the matching degree is high, and the limiting effect is good. Secondly, it reduces the manufacturing precision of the limiting posts and limiting groove to a certain extent, which helps to improve the production efficiency of the circuit breaker cover.

[0096] For example, refer to Figure 4and Figure 5 As shown, the cover body 1 is provided with two limiting posts, and the information carrier 2 is provided with a strip-shaped limiting groove. The arrangement direction of the two limiting posts on the cover body 1 is consistent with the length direction of the strip-shaped limiting groove. When the latching protrusion and the latching groove are engaged, both limiting posts extend into the strip-shaped limiting groove. The outer parts of the two limiting posts contact and are clearance-fitted with the inner wall of the strip-shaped limiting groove in the width direction, and the outer walls of the opposite sides of the two limiting posts contact and are clearance-fitted with the inner wall of the strip-shaped limiting groove in the length direction. The structure is simple and the limiting effect is good. Furthermore, it reduces the manufacturing precision and helps to improve production efficiency.

[0097] refer to Figure 2 and Figure 4 As shown, in some embodiments, the cover body 1 is provided with a mounting groove 91 for installing the information carrier 2, a limiting post is provided at the bottom of the mounting groove 91, and the second connecting part 4 is provided inside the mounting groove 91.

[0098] By providing a mounting groove 91 on the cover body 1, both the limiting post and the second connecting part 4 are placed within the mounting groove 91. On the one hand, the mounting groove 91 provides support for the information carrier 2, thus improving the connection stability and reliability of the information carrier 2 on the cover body 1. On the other hand, since both the limiting post and the second connecting part 4 are placed within the mounting groove 91, the mounting groove 91 provides protection for the limiting post and the second connecting part 4, helping to extend their service life.

[0099] In a specific implementation, the second connecting part 4, for example, a slot, can be set on the wall of the mounting groove 91. Of course, the slot can also be set on the bottom of the mounting groove 91.

[0100] The slot can be a through slot, with a large mating surface between the convex and the slot, resulting in a strong locking connection. Of course, the slot can also be a blind slot.

[0101] refer to Figure 4 As shown, the cover body 1 is provided with two slots. The inner cavity of the mounting groove 91 on the second protrusion can be, for example, a rectangular structure, and the mounting groove 91 has two sets of opposing sidewalls. The two slots can be respectively formed on the two sidewalls in the width direction of the mounting groove 91.

[0102] Of course, the two slots can also be provided at the bottom of the mounting slot 91 or on the two side walls along the length of the mounting slot 91.

[0103] refer to Figure 2 and Figure 4As shown, in some embodiments, the cover body 1 is provided with a first protrusion 8 and a second protrusion 9 located on one side of the first protrusion 8. The first protrusion 8 is provided with a handle groove 81 for a circuit breaker, and the second protrusion 9 is provided with a mounting groove 91 for installing the information carrier 2. The second connecting part 4 is disposed in the mounting groove 91. When the second connecting part 4 and the first connecting part 3 are connected, the information marking surface 21 covers the opening of the mounting groove 91 and is flush with the side of the first protrusion 8 facing away from the cover body 1.

[0104] The cover body 1 has a first protrusion 8 with a handle groove 81 for mounting a circuit breaker handle. The cover body 1 also has a second protrusion 9, located to one side of the first protrusion 8. A mounting groove 91 is provided on the second protrusion 9, and a second connecting part 4 is disposed within the mounting groove 91. The first connecting part 3 and the second connecting part 4 cooperate to connect. When the information carrier 2 is installed on the mounting groove 91, the information label surface 21 covers the opening of the mounting groove 91. This arrangement allows the mounting groove 91 to support the information carrier 2, resulting in higher stability and reliability of the connection between the information carrier 2 and the cover body 1.

[0105] In addition, since the information label surface 21 is flush with the side of the first protrusion 8 that is away from the cover body 1, after the information carrier 2 is connected to the cover body 1, the flatness between the information label surface 21 and the cover body 1 is good, which has a better integrated visual effect and improves the aesthetics.

[0106] A first protrusion 8 and a second protrusion 9 are provided on the cover body 1. The handle groove 81 is opened on the first protrusion 8, and the mounting groove 91 for installing the information carrier 2 is set on the second protrusion 9. In this way, when the circuit breaker with the circuit breaker cover of this embodiment is installed on the equipment, such as the power distribution cabinet, it is convenient to expose the handle and the information label surface 21 at the window of the power distribution cabinet, which is convenient to operate the handle and also convenient to observe the preset information, and the visualization effect is better.

[0107] In practice, the first protrusion 8 and the second protrusion 9 can be integrally formed with the cover body 1, resulting in good integrity and high load-bearing strength.

[0108] refer to Figure 2 , Figures 6 to 9 As shown, in some embodiments, at least a first chamfer 82 is provided on the side of the first protrusion 8 away from the cover body 1, and at least a second chamfer 22 is provided on the side of the information marking surface 21. The second chamfer 22 and the first chamfer 82 have the same structure, and the information marking surface 21 has the same color as the first protrusion 8.

[0109] The first chamfer 82 on the first protrusion 8 has the same structure as the second chamfer 22 on the information label surface 21, and the information label surface 21 and the first protrusion 8 have the same color. This makes the consistency and integrity of the information label surface 21 and the first protrusion 8 better, thereby further improving the integrated visual effect and aesthetics.

[0110] refer to Figure 2 As shown, in some embodiments, the second protrusion 9 is disposed close to the first protrusion 8 so that the information marking surface 21 is close to the first protrusion 8, and the first chamfer 82 and the second chamfer 22 are aligned at the junction of the information carrying surface and the first protrusion 8.

[0111] The second protrusion 9 is positioned close to the first protrusion 8, meaning the second protrusion 9 is adjacent to the first protrusion 8. This arrangement ensures that after the information carrier 2 is connected to the cover body 1, the information label surface 21 and the side of the first protrusion 8 facing away from the cover body 1 are not only flush but also adjacent to each other. Furthermore, the first chamfer 82 and the second chamfer 22 are aligned at their junction, thereby improving the consistency and integrity of the information label surface 21 and the first protrusion 8, further enhancing the integrated visual effect and aesthetics.

[0112] For specific implementation, refer to Figure 2 As shown, the first boss 8, except for the side closest to the second boss 9, has a first chamfer 82 on all its sidewalls. The first chamfer 82 is arranged in a U-shape on the first boss 8. (Reference) Figures 6 to 9 As shown, the information label surface 21 has a second chamfer 22 on all side walls except the side closest to the first boss 8. The second chamfer 22 is arranged in a U-shape on the second boss 9. The U-shaped opening of the first chamfer 82 and the U-shaped opening of the second chamfer 22 are aligned at the junction of the first boss 8 and the information label surface 21, which improves the aesthetics.
