Among them, the first limiting part is provided with a first fixing part, and the second limiting part is provided with a second fixing part. When the first limiting part cooperates with the second limiting part, the first fixing part and the second fixing part are fixed, so that the handle body and the handle sleeve are fixedly connected.
[0006] Based on the above, the first limiting part is provided on the side wall of the installation part, the second limiting part is provided on the wall of the installation cavity, and the installation part is a part of the handle body, and the installation cavity is provided in the handle sleeve. Therefore, the connection between the handle body and the handle sleeve can be realized through the cooperation of the first limiting part and the second limiting part. On this basis, the first limiting part is provided with a first fixing part, and the second limiting part is provided with a second fixing part. The connection reliability between the handle body and the handle sleeve can be further ensured through the cooperation of the first fixing part and the second fixing part. During the use of the circuit breaker, the possibility of the handle sleeve being separated from the handle body is reduced.
[0007] When the connection between the handle sleeve and the handle body is realized through the cooperation of the first limiting part and the second limiting part, the connection between the handle sleeve and the handle body can be further limited by setting the connection between the first fixing part and the second fixing part, and the connection reliability between the handle sleeve and the handle body is further ensured.
[0008] In some possible implementation manners, the first limiting portion is a limiting protrusion, the second limiting portion is a limiting groove, and at least part of the limiting protrusion extends into the limiting groove. Or, the first limiting portion is a limiting groove, the second limiting portion is a limiting protrusion, and at least part of the limiting protrusion extends into the limiting groove.
[0009] Since one of the limiting protrusion and the limiting groove is arranged on the installation portion, and the other is arranged on the cavity wall of the installation cavity, and the installation portion is a part of the handle body, and the installation cavity is arranged in the handle sleeve. Therefore, the connection between the handle sleeve and the handle body can be realized through the cooperation of the limiting protrusion and the limiting groove, ensuring the connection reliability between the handle sleeve and the handle body. During the use of the circuit breaker, the possibility of the handle sleeve being separated from the handle body is reduced.
[0010] In some possible implementation manners, the first fixing portion is a fixing protrusion, the second fixing portion is a fixing groove, and at least part of the fixing protrusion extends into the fixing groove. Or, the first fixing portion is a fixing groove, the second fixing portion is a fixing protrusion, and at least part of the fixing protrusion extends into the fixing groove.
[0011] Since one of the fixing protrusion and the fixing groove is arranged on the first limiting portion, and the other is arranged on the second limiting portion, and the first limiting portion is arranged on a part of the handle body, and the second limiting portion is arranged on the handle sleeve. Based on this, the first limiting portion and the second limiting portion can be limited through the cooperation of the fixing protrusion and the fixing groove, further ensuring the connection reliability between the handle sleeve and the handle body.
[0012] In some possible implementation manners, the fixing protrusion is configured as a triangular prism, a quadrangular prism or a cylinder.
[0013] In some possible implementation manners, the fixing protrusion is provided with a clamping groove, the fixing groove is provided with a clamping protrusion, and when the fixing protrusion and the fixing groove are matched, the clamping protrusion and the clamping groove are clamped. Or, the fixing protrusion is provided with a clamping protrusion, the fixing groove is provided with a clamping groove, and when the fixing protrusion and the fixing groove are matched, the clamping protrusion and the clamping groove are clamped. The axis of the clamping protrusion is arranged at an angle with the axis direction of the fixing protrusion, so that the clamping protrusion limits the handle sleeve and the handle body in a direction different from that of the fixing protrusion.
[0014] During the process that an operator applies a force to the handle body through the handle sleeve, the cooperation of the clamping protrusion and the clamping groove and the cooperation of the fixing protrusion and the fixing groove can limit the handle sleeve and the handle body in different directions, ensuring the connection reliability between the handle sleeve and the handle body. During the closing process of the circuit breaker, the possibility of the handle sleeve being separated from the handle body is reduced.
[0015] In some possible implementation manners, the first fixing portion is provided with a first guiding surface, and the inclination direction of the first guiding surface is adapted to the assembling direction of the handle body. And / or, the second fixing portion is provided with a second guiding surface, and the inclination direction of the second guiding surface is adapted to the assembling direction of the handle sleeve.
[0016] By providing the first guiding surface and the second guiding surface, the assembling efficiency of the fixing protrusion and the fixing groove can be improved, and further the assembling efficiency of the handle sleeve and the handle body can be improved.

The number of the installation cavities is equal to the number of the handle bodies, and the installation cavities correspond to the handle bodies one by one, and each installation cavity is provided with a handle body. Based on this, since a plurality of installation cavities are all arranged in the handle sleeve, the handle bodies installed in different installation cavities can move along with the movement of the handle sleeve.

[0020] In the example of the present application, the first fixing portion is arranged on one side of the handle body facing the closing pressing surface, and the second fixing portion is arranged on the cavity wall of the installation cavity close to the closing pressing surface. During the closing process of the circuit breaker, through the cooperation of the first fixing portion and the second fixing portion, part of the acting force applied by the operator to the handle body through the handle sleeve can be offset, reducing the possibility of the handle sleeve and the handle body being separated.
[0021] In some possible implementation manners, the closing pressing surface is provided with an anti-slip structure. Or, both the closing pressing surface and the tripping pressing surface are provided with anti-slip structures.
[0022] By providing the anti-slip structure, the friction force of the closing pressing surface can be increased.

Obviously, the described examples are some, but not all, of the examples of the present application. All other examples obtained by those of ordinary skill in the art based on the examples in the present application without making creative efforts shall fall within the protection scope of the present application.
[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the description of the application herein are for the purpose of describing specific examples only and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the description and claims of this application and the accompanying drawings are intended to cover non-exclusive inclusion.
[0037] As used herein, the mention of "example" means that a particular feature, structure, or characteristic described in connection with the example can be included in at least one example of this application. The phrase "example" appearing in various places in the specification does not necessarily refer to the same example, nor is it an independent or alternative example mutually exclusive with other examples. Those skilled in the art will explicitly and implicitly understand that the examples described herein can be combined with other examples.
[0038] The term "and / or" herein is merely a description of the relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can mean: there is A, there is both A and B, and there is B. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.
[0039] The orientation terms appearing in the following description are all the directions shown in the figures and do not limit the specific structure of the operating handle of this application.
[0040] In addition, the terms "first", "second", etc. in the description and claims of this application or the above-mentioned drawings are used to distinguish different objects and are not used to describe a specific order, and may explicitly or implicitly include one or more of such features.
[0041] In the description of this application, unless otherwise specified, "a plurality of" means two or more (including two). Similarly, "a plurality of groups" means two or more groups (including two groups).
[0042] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0043] A switchgear is an electrical component for protecting a circuit. The switchgear can be a circuit breaker or other device that adjusts its working state through an operating handle.
[0044] Taking the switchgear as a circuit breaker as an example, the circuit breaker can switch from the closed state to the tripped state when there is an overload or short circuit in the circuit, making the circuit in an open state to protect the circuit. The circuit breaker generally includes an operating handle, an operating mechanism and a contact mechanism. The operating handle can directly or indirectly drive the operating mechanism to move, the operating mechanism can drive the contact mechanism to act, and the contact mechanism includes a moving contact and a static contact. The moving contact can contact or separate from the static contact under the drive of the operating mechanism. When the moving contact contacts the static contact, the circuit breaker is closed. When the moving contact separates from the static contact, the circuit breaker is tripped.
[0045] When the circuit breaker is used as a single-pole circuit breaker, the operator directly adjusts the use state of the circuit breaker through the operating handle. Since in the relevant circuit breakers, the size of the operating handle is small, it is inconvenient for the operator to adjust the use state of the circuit breaker through the operating handle.
[0046] In the related art, a handle sleeve is provided for the operating handle. However, based on the structure of the existing handle sleeve, during the use of the circuit breaker, especially during the closing process of the circuit breaker, the handle sleeve is prone to detach from the handle body.
[0047] Based on the above, the present application example provides an operating handle and a switchgear.
[0048] In order to enable those skilled in the art to better understand the solution of the present application, the operating handle and the switchgear provided by the present application example will be clearly and completely described below with reference to the drawings.
[0049] Exemplarily, the present application example provides a switchgear. The switchgear can be a circuit breaker or other device that adjusts its working state through an operating handle. The switchgear can be single-pole, and the switchgear can also be multi-pole. The present application example is only described by taking the switchgear as a three-pole circuit breaker as an example.
[0050] Figure 1 For a structural schematic diagram of a circuit breaker provided by the present application example, please refer to Figure 1 , the circuit breaker 100 can include a housing, an operating mechanism and an operating handle. The housing can provide space for the operating mechanism and the operating handle. The operating handle is connected to the operating mechanism, and the operating mechanism is rotatably installed in the housing. By operating the handle, the operating mechanism can be controlled to make the switchgear switch between the closed state and the tripped state. The operating handle can include a handle body 110 and a handle sleeve 120 connected to each other.
[0051] The housing of the circuit breaker 100 can be made of an insulating material, such as polyamide (also known as PA plastic), etc.
[0052] The housing made of insulating material can reduce the possibility of current leakage inside the housing, ensuring the safety of use of the circuit breaker 100.
[0053] The operating handle is connected to the operating mechanism of the circuit breaker 100. By applying a force to the operating handle, the operator can drive the operating mechanism to act, causing the circuit breaker 100 to switch between opening and closing.
[0054] Next, the operating handle will be described in detail.
[0055] Exemplarily, the present application provides an operating handle. Figure 2 FIG. [X] is a schematic structural view of an operating handle provided by an example of the present application from a first perspective. Figure 3 FIG. [X] is an exploded schematic structural view of an operating handle provided by an example of the present application. Figure 4 FIG. [X] is a schematic structural view of an operating handle provided by an example of the present application from a second perspective. Figure 5 is Figure 4 a cross-sectional view taken along line A-A in
[0056] Please refer to Figures 2 to 5 , the operating handle may include a handle body 110 and a handle sleeve 120. The handle body 110 may include a mounting portion 111, and a first limiting portion 1111 is provided on the side wall of the mounting portion 111. The handle sleeve 120 includes a mounting cavity 121 for accommodating the mounting portion 111, and a second limiting portion 1211 is provided in the mounting cavity 121. The first limiting portion 1111 cooperates with the second limiting portion 1211. Among them, the first limiting portion 1111 is provided with a first fixing portion 1112, and the second limiting portion 1211 is provided with a second fixing portion 1212. When the first limiting portion 1111 cooperates with the second limiting portion 1211, the first fixing portion 1112 and the second fixing portion 1212 are fixedly matched to fixedly connect the handle body 110 and the handle sleeve 120.
[0057] The handle body 110 may be made of insulating material, such as nylon, polybutylene terephthalate, etc.
[0058] The manufacturing material of the handle sleeve 120 may be the same as that of the handle body 110, as long as it is ensured that the handle sleeve 120 is made of insulating material and the handle sleeve 120 has a certain elastic deformation ability.
[0059] The mounting portion 111 may refer to the part of the handle body 110 that can extend into the mounting cavity 121. The mounting portion 111 may be rectangular, semi-circular, a combination of rectangular and semi-circular, or other shapes.
[0060] Note: The figures in the English translation are marked as [X] as the specific figure numbers are not provided in the original text. You may need to replace them with the actual figure numbers according to the context.The shape of the installation cavity 121 may be the same as that of the installation part 111, or may be different from that of the installation part 111. As long as the installation cavity 121 can provide an installation space for the installation part 111.
[0061] The orifice of the installation cavity 121 may be arranged facing the operating mechanism.
[0062] When the circuit breaker 100 is a multi-pole circuit breaker 100, the multi-pole circuit breaker 100 includes a plurality of handle bodies 110. The installation part 111 can be inserted into the installation cavity 121 along the arrangement direction of the plurality of handle bodies 110 and cooperate with the installation cavity 121. At this time, along the assembly direction of the handle sleeve 120, the size of the installation cavity 121 should be larger than that of the installation part 111 to ensure that the installation part 111 can be inserted into the installation cavity 121.
[0063] The installation part 111 can also be inserted into the installation cavity 121 from the orifice of the installation cavity 121 along the arrangement direction of the operating mechanism and the handle sleeve 120. At this time, along the arrangement direction of the plurality of handle bodies 110, the size of the installation cavity 121 can be less than or equal to that of the installation part 111 to ensure the assembly reliability of the handle sleeve 120 and the handle body 110.
[0064] Based on the different number of poles of the circuit breaker 100, the number of handle bodies 110 of the circuit breaker 100 is also different. The number of handle bodies 110 of each circuit breaker 100 is equal to and corresponds one-to-one with the number of poles of the circuit breaker 100.
[0065] The number of installation cavities 121 is equal to the number of handle bodies 110 and the installation cavities 121 correspond to the handle bodies 110 one-to-one.
[0066] There may be two first limiting parts 1111, and the two first limiting parts 1111 can be respectively arranged on two opposite side walls of the installation part 111. There may also be only one first limiting part 1111, and the first limiting part 1111 can be arranged on any one side wall of the installation part 111.
[0067] There may be only one second limiting part 1211 in the installation cavity 121, or there may be a plurality of second limiting parts 1211 arranged at intervals in the installation cavity 121. The number of second limiting parts may be equal to and correspond one-to-one with the number of first limiting parts 1111. The number of second limiting parts 1211 may also be different from the number of first limiting parts 1111. A plurality of first limiting parts 1111 may cooperate with the same second limiting part 1211, or one first limiting part 1111 may cooperate with a plurality of second limiting parts 1211. The examples of this application do not make specific limitations on this.
[0068] One of the first limiting part 1111 and the second limiting part 1211 can be a protrusion, and the other can be set as a groove. At least part of the protrusion can extend into the groove and cooperate with the groove to realize the cooperation between the handle body 110 and the handle sleeve 120.
[0069] The first fixing part 1112 can be a groove or a protrusion provided on the first limiting part 1111. When the first fixing part 1112 is set as a groove, the second fixing part 1212 can be set as a protrusion. When the first limiting part 1111 is set as a protrusion, the second limiting part 1211 can be set as a groove.
[0070] Based on the above, the first limiting part 1111 is provided on the side wall of the installation part 111, and the second limiting part 1211 is provided on the wall of the installation cavity 121. Moreover, the installation part 111 is a part of the handle body 110, and the installation cavity 121 is provided in the handle sleeve 120. Therefore, the connection between the handle body 110 and the handle sleeve 120 can be realized through the cooperation between the first limiting part 1111 and the second limiting part 1211. On this basis, the first limiting part 1111 is provided with the first fixing part 1112, and the second limiting part 1211 is provided with the second fixing part 1212. The connection reliability between the handle body 110 and the handle sleeve 120 can be further ensured through the cooperation between the first fixing part 1112 and the second fixing part 1212. During the use of the circuit breaker 100, the possibility of the handle sleeve 120 separating from the handle body 110 is reduced.
[0071] When the connection between the handle sleeve 120 and the handle body 110 is realized through the cooperation between the first limiting part 1111 and the second limiting part 1211, the connection between the handle sleeve 120 and the handle body 110 can be further limited by setting the connection between the first fixing part 1112 and the second fixing part 1212, and the connection reliability between the handle sleeve 120 and the handle body 110 is further ensured.
[0072] In addition, according to the operating handle provided by the example of the present application, the handle sleeve 120 is sleeved on the handle body 110, which can increase the contact area between the operating handle and the operator. Furthermore, it is convenient for the operator to drive the operating mechanism to act through the operating handle, and then adjust the working state of the circuit breaker.
[0073] Next, an exemplary description will be made on the specific implementation manners of the first limiting part 1111 and the second limiting part 1211.
[0074] Based on the operating handle provided by the above example, Figure 6 is a schematic structural diagram of a handle body provided by an example of the present application, Figure 7 is a schematic structural diagram of a handle sleeve provided by an example of the present application. Please refer to Figure 6 and Figure 7, the first limiting part can be a limiting protrusion, the second limiting part can be a limiting groove, and at least part of the limiting protrusion can extend into the limiting groove. Alternatively, the first limiting part 1111 can also be a limiting groove, the second limiting part 1211 can also be a limiting protrusion, and at least part of the limiting protrusion extends into the limiting groove.
[0075] The first limiting part 1111 can be a limiting protrusion or a limiting groove. When the first limiting part 1111 is a limiting groove, the second limiting part 1211 can be a limiting protrusion. When the first limiting part 1111 is a limiting protrusion, the second limiting part 1211 is a limiting groove. In two different implementation manners, the structures of the limiting protrusion and the limiting groove are similar and the functions they perform are similar. Hereinafter, only taking the case where the first limiting part 1111 is a limiting groove and the second limiting part 1211 can be a limiting protrusion as an example, the first limiting part 1111 and the second limiting part 1211 will be described.
[0076] When the first limiting part 1111 is a limiting groove, the second limiting part 1211 can be a limiting protrusion. The limiting protrusion can be a columnar structure, such as a cylinder, a triangular prism, a quadrangular prism or other columnar structures. The specific implementation manner of the limiting protrusion is not limited in this application example. When the limiting protrusion is a columnar structure, the axis of the columnar structure can be parallel to the assembly direction of the handle sleeve 120.
[0077] The shape of the limiting groove can be similar to the shape of the limiting protrusion. Through the cooperation of the limiting protrusion and the limiting groove, the fitting degree of the limiting protrusion and the limiting groove can be ensured, and the amplitude of the handle sleeve 120 shaking relative to the handle body 110 can be reduced.
[0078] Based on the above, since one of the limiting protrusion and the limiting groove is provided on the mounting part 111 and the other is provided on the cavity wall of the mounting cavity 121, and the mounting part 111 is a part of the handle body 110 and the mounting cavity 121 is provided in the handle sleeve 120. Therefore, the connection between the handle sleeve 120 and the handle body 110 can be realized through the cooperation of the limiting protrusion and the limiting groove, and the connection reliability between the handle sleeve 120 and the handle body 110 can be ensured. During the use of the circuit breaker 100, the possibility of the handle sleeve 120 separating from the handle body 110 is reduced.
[0079] Based on the operating handle provided in the above example, please refer to Figure 6 and Figure 7 , the first fixing part 1112 can be a fixing protrusion, the second fixing part 1212 can be a fixing groove, and at least part of the fixing protrusion extends into the fixing groove. Alternatively, the first fixing part can also be a fixing groove, the second fixing part can also be a fixing protrusion, and at least part of the fixing protrusion extends into the fixing groove.
[0080] In the assembly direction of the handle sleeve 120, the size of the first fixing portion 1112 can be smaller than the size of the first limiting portion 1111, or the size of the first fixing portion 1112 can be equal to the size of the first limiting portion 1111.
[0081] In the assembly direction of the handle sleeve 120, the size of the fixing protrusion can be equal to the size of the fixing groove, or the size of the fixing protrusion can be smaller than the size of the fixing groove.
[0082] The number of fixing grooves can be equal to the number of fixing protrusions. In this case, one fixing groove can cooperate with one fixing protrusion.
[0083] The number of fixing grooves can also be smaller than the number of fixing protrusions. In this case, one fixing groove can cooperate with multiple fixing protrusions. Or, one fixing groove can cooperate with one fixing protrusion.
[0084] The shape of the fixing protrusion can be similar to the shape of the fixing groove, so as to ensure the assembly reliability of the fixing protrusion and the fixing groove when they cooperate, and reduce the possibility of the fixing protrusion shaking relative to the fixing groove.
[0085] Exemplarily, the fixing protrusion can be in the shape of a prism, a cylinder, etc.
[0086] When the first limiting portion 1111 is a limiting groove and the second limiting portion 1211 is a limiting protrusion, the first fixing portion 1112 can be a fixing protrusion provided on the groove wall of the limiting groove, and the second fixing portion 1212 can be a fixing groove provided on the limiting protrusion. Or, the first fixing portion can be a fixing groove provided on the groove wall of the limiting groove, and the second fixing portion can be a fixing protrusion provided on the limiting protrusion.
[0087] When the first limiting portion is a limiting protrusion and the second limiting portion is a limiting groove, the first fixing portion can be a fixing protrusion provided on the groove wall of the limiting groove, and the second fixing portion can be a fixing groove provided on the limiting protrusion. Or, the first fixing portion can be a fixing groove provided on the groove wall of the limiting groove, and the second fixing portion can be a fixing protrusion provided on the limiting protrusion. The specific implementation manners of the first fixing portion and the second fixing portion in this application example are not limited.
[0088] Based on the above, since one of the fixing protrusion and the fixing groove is provided on the first limiting portion 1111 and the other is provided on the second limiting portion 1211, and the first limiting portion 1111 is provided on a part of the handle body 110 and the second limiting portion 1211 is provided on the handle sleeve 120, based on this, the first limiting portion and the second limiting portion 1211 can be limited by the cooperation of the fixing protrusion and the fixing groove, further ensuring the connection reliability between the handle sleeve 120 and the handle body 110.
[0089] Based on the operating handle provided in the above example, the fixing protrusion can be set as a triangular prism, a quadrangular prism, a cylinder, an elliptical cylinder or a structure of other shapes. Figure 5 Taking only the cross-section of the fixing protrusion being an equilateral triangle as an example.
[0090] The cross-section of the triangular prism can be an equilateral triangle or any triangle. The cross-section of the quadrangular prism can be a rectangle, a square, a parallelogram or any quadrilateral.
[0091] When the cross-section of the fixing protrusion is an equilateral triangle, because the cross-section of the fixing protrusion is an equilateral triangle and a triangle has stability, the fixing protrusion is not easily deformed and can withstand a large acting force. In addition, since the cross-section of the fixing protrusion is an equilateral triangle, during the process of the operator applying an acting force to the handle body 110 through the handle sleeve 120, the force on each surface of the fixing protrusion is relatively uniform. Therefore, the fixing protrusion can withstand a large acting force, and during the closing process of the circuit breaker 100, the handle sleeve 120 is not easily detached from the handle body 110, ensuring the connection reliability between the handle sleeve 120 and the handle body 110 and ensuring the use reliability of the circuit breaker 100.
[0092] Based on the operating handle provided in the above example, the connection reliability between the handle sleeve 120 and the handle body 110 can be further ensured by the interference fit between the fixing protrusion and the fixing groove. The connection reliability between the handle sleeve 120 and the handle body 110 can also be further ensured by the interference fit between the limiting protrusion and the limiting groove. The connection reliability between the handle sleeve 120 and the handle body 110 can also be further ensured by the snap connection between the fixing groove and the fixing protrusion. The connection reliability between the handle sleeve 120 and the handle body 110 can also be further ensured by the snap connection between the limiting protrusion and the limiting groove. The following only describes the example of the snap connection between the fixing protrusion and the fixing groove.
[0093] Exemplarily, the fixing protrusion can be provided with a snap groove, and the fixing groove can be provided with a snap protrusion. When the fixing protrusion and the fixing groove are matched, the snap protrusion and the snap groove are snap-connected. Or, the fixing protrusion is provided with a snap protrusion 1113, and the fixing groove is provided with a snap groove. When the fixing protrusion and the fixing groove are matched, the snap protrusion 1113 and the snap groove are snap-connected. Among them, the axis of the snap protrusion 1113 is arranged at an angle with the axis direction of the fixing protrusion, so that the snap protrusion 1113 limits the handle sleeve 120 and the handle body 110 in a direction different from that of the fixing protrusion.
[0094] One or more snap protrusions 1113 can be provided. The snap protrusion can be at least one of a convex point, a convex column, a convex platform, etc. The shape of the snap groove is adapted to the shape of the snap protrusion 1113.
[0095] When the axis direction of the fixing protrusion extends along the assembly direction of the handle sleeve 120, the axis direction of the clamping protrusion 1113 can be set at an angle to the assembly direction of the handle sleeve 120, and this angle can be greater than 0 degrees and less than 90 degrees.
[0096] Based on this, during the process that an operator applies a force to the handle body 110 through the handle sleeve 120, the cooperation between the clamping protrusion 1113 and the clamping groove, and the cooperation between the fixing protrusion and the fixing groove can limit the handle sleeve 120 and the handle body 110 in different directions, ensuring the connection reliability between the handle sleeve 120 and the handle body 110. During the closing process of the circuit breaker 100, the possibility of the handle sleeve 120 separating from the handle body 110 is reduced.
[0097] Based on the operating handle provided in the above example, the first fixing portion 1112 is provided with a first guiding surface, and the inclination direction of the first guiding surface is adapted to the assembly direction of the handle body 110. And / or, the second fixing portion 1212 is provided with a second guiding surface, and the inclination direction of the second guiding surface is adapted to the assembly direction of the handle sleeve 120.
[0098] The operating handle can be provided with both the first guiding surface and the second guiding surface, or the handle operation can be provided with only any one of the first guiding surface and the second guiding surface. The following description is only given by taking the first guiding surface as an example.
[0099] When the first fixing portion 1112 is a fixing protrusion and the second fixing portion 1212 is a fixing groove, by setting the first guiding surface, along the assembly direction of the handle sleeve 120, the size of the fixing protrusion can be made to increase from small to large. Based on this, during the cooperation process between the first fixing portion 1112 and the second fixing portion 1212, the end with the smallest size of the fixing protrusion first extends into the fixing groove, which is convenient for improving the assembly efficiency of the fixing protrusion and the fixing groove, and further improving the assembly efficiency of the handle sleeve 120 and the handle body 110.
[0100] When the first fixing portion 1112 is a fixing groove and the second fixing portion 1212 is a fixing protrusion, by setting the first guiding surface, along the assembly direction of the handle sleeve 120, the size of the fixing groove can be made to decrease from large to small. Based on this, during the cooperation process between the first fixing portion 1112 and the second fixing portion 1212, the fixing protrusion first cooperates with the end with the largest size of the fixing groove, which is convenient for improving the assembly efficiency of the fixing protrusion and the fixing groove, and further improving the assembly efficiency of the handle sleeve 120 and the handle body 110.
[0101] Based on the above, by setting the first guiding surface and the second guiding surface, the assembly efficiency of the fixing protrusion and the fixing groove can be improved, and further the assembly efficiency of the handle sleeve 120 and the handle body 110 can be improved.
[0102] At least one of the first limiting portion 1111 and the second limiting portion 1211 may also be provided with a guiding surface to improve the assembly efficiency of the handle sleeve 120 and the handle body 110.
[0103] Based on the operating handle provided in the above example, the handle sleeve 120 may include a plurality of installation cavities 121 arranged at intervals. The number of the handle bodies 110 is equal to the number of the installation cavities 121, and the installation cavities 121 correspond to the handle bodies 110 one by one.
[0104] When the circuit breaker 100 is a multi-pole circuit breaker 100, the handle sleeve 120 may include a plurality of installation cavities 121 arranged at intervals. The number of the installation cavities 121 is equal to the number of the handle bodies 110, and the installation cavities 121 correspond to the handle bodies 110 one by one. Each installation cavity 121 is installed with a handle body 110. Based on this, since a plurality of installation cavities 121 are all arranged in the handle sleeve 120, the handle bodies 110 installed in different installation cavities 121 can move along with the movement of the handle sleeve 120. An operator can simultaneously control different poles of the circuit breaker 100 to move simultaneously through the handle sleeve 120, ensuring the reliability of the use of the circuit breaker 100.
[0105] Based on the operating handle provided in the above example, the operating handle includes a tripping pressing surface and a closing pressing surface which are oppositely arranged. The first fixing portion 1112 is arranged on one side of the handle body 110 facing the closing pressing surface, and the second fixing portion 1212 is arranged on the cavity wall of the installation cavity 121 close to the closing pressing surface.
[0106] During the use of the operating handle, an operator can apply a force to the closing pressing surface, so that the operating handle drives the operating mechanism to move, and further makes the circuit breaker close. During the closing process of the circuit breaker, the operating handle needs to overcome the elastic force of the energy storage spring in the operating mechanism. Therefore, compared with the force applied during the tripping process of the circuit breaker, during the closing process, the force applied by the operator to the operating handle is greater, and the force borne by the closing pressing surface is greater, making it easy for the handle sleeve to separate from the handle body.
[0107] In the example of the present application, the first fixing portion 1112 is arranged on one side of the handle body 110 facing the closing pressing surface, and the second fixing portion 1212 is arranged on the cavity wall of the installation cavity 121 close to the closing pressing surface. During the closing process of the circuit breaker 100, the cooperation between the first fixing portion 1112 and the second fixing portion 1212 can offset at least part of the force applied by the operator to the handle body 110 through the handle sleeve 120, reducing the possibility of the handle sleeve 120 separating from the handle body.
[0108] Based on the operating handle provided in the above example, the closing pressing surface of the operating handle may be provided with an anti-slip structure.
[0109] The anti-slip structure can be a plurality of convex structures provided on the closing pressing surface. The plurality of convex structures can be randomly arranged or orderly arranged. When the manufacturing material of the convex structure is the same as that of the handle sleeve 120, the convex structure can be injection-molded with the handle sleeve 120. The convex structure can also be made of silica gel material or other materials different from the manufacturing material of the handle sleeve 120, and the convex structure and the handle sleeve 120 can also be formed by two-color injection molding. The convex structure can also be fixedly connected to the handle sleeve 120 by other connection methods such as bonding. The examples of this application do not limit this.
[0110] The anti-slip structure can also be a plate-like structure with a large roughness, such as a sponge plate, etc. The plate-like structure can be fixedly connected to the handle sleeve 120 by connection methods such as bonding.
[0111] By providing the anti-slip structure, the friction force of the closing pressing surface can be increased, so that during the closing process of the circuit breaker 100, the operator can more easily close the circuit breaker 100 by operating the handle, improving the use reliability of the circuit breaker 100.
[0112] The closing pressing surface and the opening pressing surface of the operating handle can both be provided with anti-slip structures. The anti-slip structures of the closing pressing surface and the opening pressing surface can be the same or different.
[0113] Finally, it should be noted that the above embodiments are only specific implementation manners of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered by the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
