Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of electrical equipment, and in particular to a trip module and a circuit breaker. Background Art
[0002] The trip device, as a very important part of the leakage circuit breaker, is used to perform leakage protection and leakage indication functions.
[0003] Traditional leakage circuit breakers match different releases based on the different sizes of the shells of leakage releases of different specifications. This leads to a wide variety of materials on the production line of the release. The differences between the various materials are often small, easy to confuse, and inconvenient to manage. Utility Model Content
[0004] In view of the above problems, an embodiment of the present application provides a trip module and a circuit breaker, which solves the problem of material confusion and inconvenient management caused by a wide variety of materials in the production process of the trip module by adding a mounting base.
[0005] According to one aspect of an embodiment of the present application, a trip module is provided, including a trip assembly and a mounting seat, wherein the mounting seat is plug-connected to the trip assembly, and the mounting seat is used to be connected to a frame of a circuit breaker.
[0006] By adopting the above scheme, the release assembly is first assembled with the mounting seat to form a release module, and then the release module is assembled as a whole into the circuit breaker, and during assembly, the mounting seat is connected to the frame of the circuit breaker, that is, the release assembly and the frame of the circuit breaker do not need to be directly matched to achieve assembly. The assembly of the release assembly and the mounting seat adopts the form of plug-in, and the assembly of the two is more convenient and quick. It can be seen that for circuit breakers of different specifications, the structure of the release assembly does not need to be changed, and only the structural features such as the size of the mounting seat need to be changed to make it compatible with the frame of the circuit breaker. Therefore, when producing release modules corresponding to circuit breakers of various specifications, only mounting seats of different specifications need to be provided, and the structure of the release assembly does not need to be changed, thereby reducing the types of materials on the production line, reducing the probability of confusion between different materials, and facilitating production management.
[0007] In some embodiments, the release assembly and the mounting seat are arranged relative to each other along a first direction; the release assembly includes a plug-in portion, the mounting seat is provided with a slot, the plug-in portion is located in the slot, and the plug-in portion is limited by the side wall of the slot in the first direction.
[0008] By adopting the above solution, the plug-in portion can be limited by the side wall of the slot in the first direction, so that the release assembly and the mounting seat are not easily separated, which is beneficial for the release module to maintain structural stability.
[0009] In some embodiments, the slot opening faces a second direction so that the plug-in portion can be inserted into the slot along the second direction, and the second direction is perpendicular to the first direction; a notch is provided on a slot wall of the slot parallel to the second direction.
[0010] By adopting the above scheme, the insertion direction of the plug-in part in the slot is the direction in which the release assembly can move relative to the mounting seat, and this direction is perpendicular to the first direction. Therefore, even if the release assembly is displaced relative to the mounting seat, the release assembly will not be separated from the mounting seat along the first direction, which is beneficial to the structural stability of the release module while ensuring the plug-in connection between the release assembly and the mounting seat. A notch is provided on the slot wall parallel to the second direction of the slot, so that when the plug-in part is inserted into the slot along the second direction, the contact area between the plug-in part and the slot wall is small, the friction between the two is small, and the insertion of the plug-in part is more labor-saving.
[0011] In some embodiments, the slot includes a first slot segment, a second slot segment, and a third slot segment connected in sequence along the second direction, the first slot segment is close to the slot opening; in the third direction, the width of the first slot segment is greater than the width of the third slot segment, and both ends of the second slot segment are respectively connected to the first slot segment and the third slot segment; the third direction is perpendicular to the second direction.
[0012] By adopting the above scheme, during the process of inserting the plug-in part into the slot, it first enters the first slot section from the slot opening. Since the first slot section has a larger size in the third direction, it is easier for the plug-in part to move in the first slot section. The plug-in part is then inserted from the first slot section to the second slot section. During this process, the size of the slot in the third direction gradually decreases, guiding the plug-in part to a position where it can be inserted into the third slot section. Finally, the plug-in part is inserted into the third slot section to complete the plug-in connection between the circuit breaker assembly and the mounting seat. By providing the first slot section, the second slot section and the third slot section, it is possible to meet the requirements of saving effort during the process of inserting the plug-in part into the slot and not being easy to move after being inserted into place.
[0013] In some embodiments, the mounting seat further includes a limiting member, which is disposed on a side of the plug-in portion close to the notch.
[0014] By adopting the above solution, the limiting member can limit the movement of the plug-in portion in the direction of the notch, thereby preventing the plug-in portion from sliding out of the slot, which is beneficial to maintaining the connection stability between the release assembly and the mounting seat.
[0015] In some embodiments, the limiting member includes a limiting protrusion provided on the slot wall of the slot, and the limiting protrusion abuts against the plug-in portion.
[0016] By adopting the above solution, the limiting protrusion abuts against the plug-in part, which can prevent the plug-in part from moving relative to the slot, and such a limiting member has a simple structure and is easy to process.
[0017] In some embodiments, a height T of the limiting protrusion protruding from the slot wall of the slot satisfies: 1.5 mm ≤ T ≤ 0.5 mm.
[0018] By adopting the above solution, if the height of the limiting protrusion protruding from the slot is too high, it will hinder the plug-in part from being inserted into the slot, and if the height of the limiting protrusion protruding from the slot is too low, the limiting of the plug-in part is not reliable enough. Therefore, the above height range enables the plug-in part to be inserted into the slot under the action of external force applied by personnel, and prevents the plug-in part from accidentally falling out of the slot when no external force is applied by personnel, which is conducive to the assembly and fixation of the release assembly and the mounting seat.
[0019] In some embodiments, the limiting member includes a connecting member, which is connected to the mounting seat and abuts against the plug-in portion.
[0020] By adopting the above solution, before the plug-in part is inserted into the slot, the connecting part may not be connected to the mounting seat first, and after the plug-in part is inserted into the slot, the connecting piece is connected to the mounting seat and abuts against the plug-in part, which can play a role in limiting the movement of the plug-in part relative to the slot. It can be seen that during the assembly process of the release assembly and the mounting seat, the connecting piece can be flexibly removed or installed as needed, which facilitates the assembly and limiting of the release assembly and the mounting seat.
[0021] In some embodiments, the trip module further includes a support member, which is disposed between the mounting seat and the trip assembly and is used to limit the positions of the mounting seat and the trip assembly in relative directions.
[0022] By adopting the above solution, the support member can limit the relative positions of the mounting seat and the release assembly, thereby preventing the mounting seat and the release assembly from being loosened or moved due to a loose connection.
[0023] According to another aspect of an embodiment of the present application, a circuit breaker is provided, comprising the trip module in any one of the above embodiments.
[0024] The embodiment of the present application sets a tripper assembly and a mounting seat in the tripping module, so that for circuit breakers of different specifications, the structure of the tripper assembly does not need to be changed, and only the size and other structural features of the mounting seat need to be changed to make it compatible with the housing of the circuit breaker. Therefore, when producing tripping modules corresponding to circuit breakers of various specifications, only mounting seats of different specifications need to be provided, and the structure of the tripper assembly does not need to be changed, thereby reducing the types of materials on the production line, reducing the probability of confusion between different materials, and facilitating production management.

[0037] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the trip module or circuit breaker of the present application. For example, in the description of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.
[0038] Furthermore, the expressions of the indicated directions, such as the X direction, the Y direction, and the Z direction, used to illustrate the operation and construction of the components of the trip module or the circuit breaker of the present embodiment are not absolute but relative, and although these indications are appropriate when the components of the trip module or the circuit breaker are in the positions shown in the figures, when these positions are changed, these directions should be interpreted differently to correspond to the changes.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0042] Traditional leakage circuit breakers match different releases based on the different sizes of the shells of leakage releases of different specifications. This leads to a wide variety of materials on the production line of the release. The differences between the various materials are often small, easy to confuse, and inconvenient to manage.
[0043] In view of the above problems, an embodiment of the present application provides a trip module and a circuit breaker.
[0044] like Figure 1 As shown, the trip module of the embodiment of the present application includes a trip assembly 100 and a mounting base 200. The mounting base 200 is plug-connected to the trip assembly 100, and the mounting base 200 is used to be connected to the frame of the circuit breaker.
[0045] The trip unit assembly 100 performs the leakage protection and leakage indication functions. As long as the main structure for performing the functions remains unchanged, other structures can be adaptively changed according to actual needs.
[0046] In the embodiment of the present application, the structure of the release assembly 100 may be the same as or similar to that of the release assembly 100 in the related art, and the embodiment of the present application is not limited to this.
[0047] The mounting base 200 serves as a connecting medium between the release assembly 100 and the frame of the circuit breaker. It is not only required to be connected to the release assembly, but also to be connected to the frame. The arrangement of the mounting base 200 makes it unnecessary for the release assembly 100 to be in direct contact or connection with the frame. Therefore, the release assembly 100 does not need to strictly adapt to the structure and space size of the frame.
[0048] The mounting seat 200 may be in the shape of a flat plate, a hollow shell, etc., and its material may be insulating materials such as plastics, rubber, etc. The present embodiment of the application does not limit the structure and material of the mounting seat 200.
[0049] Plug-in connection refers to a connection method in which a structure on one part is inserted into a structure on another part to achieve a connection between the two parts. When this connection method is adopted, the connection between the two parts is more convenient and quick. For example, a plug-in portion 110 can be provided on the release assembly 100, and a slot 210 can be provided on the mounting seat 200.
[0050] For details, please refer to Figure 1 , Figure 2 and Figure 3 The release assembly 100 and the mounting seat 200 are arranged relatively to each other along the first direction X; the release assembly 100 includes a plug-in portion 110, and the mounting seat 200 is provided with a slot 210, the plug-in portion 110 is located in the slot 210, and the plug-in portion 110 is limited by the side wall of the slot 210 in the first direction X.
[0051] Since the release assembly 100 and the mounting seat 200 are arranged relatively to each other along the first direction X, if the positions of the release assembly 100 and the mounting seat 200 in the first direction X are not restricted, it is possible that the release assembly 100 and the mounting seat 200 are separated. Through the above solution, the plug-in portion 110 can be restricted by the side wall of the slot 210 in the first direction X, so that the release assembly 100 and the mounting seat 200 are not easily separated, which is conducive to maintaining the structural stability of the release module.
[0052] When assembling the circuit breaker, the trip assembly 100 is first assembled with the mounting base 200 to form a trip module, and then the trip module is assembled as a whole into the circuit breaker. During assembly, the mounting base 200 is connected to the frame of the circuit breaker, that is, the trip assembly 100 and the frame of the circuit breaker do not need to be directly matched to achieve assembly.
[0053] The connection between the mounting base 200 and the frame of the circuit breaker can be: a plurality of legs 400 are arranged around the mounting base, and the legs 400 are stuck in the slots on the frame to achieve the connection between the mounting base 200 and the frame.
[0054] In the case where the release assembly 100 does not need to be directly matched with the frame of the circuit breaker, the structure of the release assembly 100 does not need to be changed for circuit breakers of different specifications, and only the size and other structural features of the mounting seat 200 need to be changed to make it compatible with the frame of the circuit breaker. Therefore, when producing release modules corresponding to circuit breakers of various specifications, only mounting seats 200 of different specifications need to be provided, and the structure of the release assembly 100 does not need to be changed, thereby reducing the types of materials on the production line, reducing the probability of confusion between different materials, and facilitating production management.
[0055] In some embodiments, the slot opening of the slot 210 faces the second direction Y so that the plug-in portion 110 can be inserted into the slot 210 along the second direction Y, which is perpendicular to the first direction X. A notch 220 is disposed on the slot wall of the slot 210 parallel to the second direction Y.
[0056] The insertion direction of the plug-in portion 110 in the slot 210 is the direction in which the release assembly 100 can move relative to the mounting seat 200, and this direction is perpendicular to the first direction X. Therefore, even if the release assembly 100 is displaced relative to the mounting seat 200, the release assembly 100 will not be separated from the mounting seat 200 along the first direction X. While ensuring the plug-in connection between the release assembly 100 and the mounting seat 200, it is beneficial for the release module to maintain structural stability.
[0057] Please refer to Figure 3 A notch 220 is provided on the groove wall of the slot 210 which is parallel to the second direction Y. Thus, when the plug-in part 110 is inserted into the slot 210 along the second direction Y, the contact area between the plug-in part 110 and the groove wall of the slot 210 is small, and the friction between the two is small, so that the insertion of the plug-in part 110 is more labor-saving.
[0058] The notch 220 may be one or more and may be in the shape of a square, a circle or a hollow pattern of any shape. In addition, the notch 220 may be arranged on any one or more groove walls of the slot 210 as long as the contact area between the groove wall of the slot 210 and the plug-in portion 110 can be reduced.
[0059] like Figure 4 As shown, in some embodiments, the slot 210 includes a first slot segment 211, a second slot segment 212, and a third slot segment 213 connected in sequence along the second direction Y, and the first slot segment 211 is close to the slot opening; in the third direction, the width of the first slot segment 211 is greater than the width of the third slot segment 213, and the two ends of the second slot segment 212 are respectively connected to the first slot segment 211 and the third slot segment 213; the third direction is perpendicular to the second direction Y.
[0060] The third direction is any direction perpendicular to the second direction Y. The third direction may or may not coincide with the first direction X, and this embodiment of the present application does not specifically limit this.
[0061] When the plug-in part 110 is inserted into the slot 210 , it first enters the first slot section 211 from the slot opening. Since the first slot section 211 is larger in the third direction, it is easier for the plug-in part 110 to move in the first slot section 211 .
[0062] The plug-in portion 110 is then inserted from the first slot section 211 to the second slot section 212 . During this process, the size of the slot 210 in the third direction is gradually reduced, and the plug-in portion 110 is guided to a position where it can be inserted into the third slot section 213 .
[0063] Finally, the plug-in portion 110 is inserted into the third slot section 213 to complete the plug-in connection between the circuit breaker assembly and the mounting base 200. The third slot section 213 has the smallest size in the third direction, which can limit the plug-in portion 110 within the range of the third slot section 213, reduce or even eliminate the movement or shaking of the plug-in portion 110 in the third slot section 213, and improve the structural stability of the release assembly 100 and the mounting base 200 after assembly.
[0064] Exemplarily, the slot 210 includes a first slot section 211, a second slot section 212, and a third slot section 213 connected in sequence along the second direction Y, and the first slot section 211 is close to the slot opening. In the third direction, the width of the first slot section 211 is 20 mm (millimeter), the width of the third slot section 213 is 10 mm, the width of the end of the second slot section 212 connected to the first slot section 211 is 20 mm, the width of the end of the second slot section 212 connected to the third slot section 213 is 10 mm, and the side wall between the two ends of the second slot section 212 gradually tilts inward to form an inclined surface. The inclined surface can be used for guidance, so that when the plug-in portion 110 is inserted into the third slot section 213, it can slide along the inclined surface and enter the third slot section 213.
[0065] Therefore, the embodiment of the present application can meet the requirements of saving effort when inserting the plug-in portion 110 into the slot 210 and not being easy to move after being inserted into place by providing the first slot section 211, the second slot section 212 and the third slot section 213.
[0066] like Figure 1 and Figure 3 As shown, in some embodiments, the mounting base 200 further includes a limiting member 230 , and the limiting member 230 is disposed on a side of the plug-in portion 110 close to the notch.
[0067] By adopting the above solution, the limiting member 230 can limit the movement of the plug-in portion 110 toward the notch direction, thereby preventing the plug-in portion 110 from sliding out of the slot 210 , which is beneficial to maintaining the connection stability between the release assembly 100 and the mounting seat 200 .
[0068] The structure of the limiter 230 can be varied. It is understandable that the structure of the limiter 230 needs to meet the following conditions: it should not affect the insertion of the plug-in portion 110 into the slot 210 , and it should be able to limit the movement of the plug-in portion 110 sliding out of the slot 210 .
[0069] Optionally, in some embodiments, the limiting member 230 includes a limiting protrusion provided on the slot wall of the slot 210, and the limiting protrusion abuts against the plug-in portion 110. For details, see Figure 1 The upper limiting member 230 .
[0070] The limiting protrusion refers to a structure protruding from the slot wall of the slot 210. For example, the limiting protrusion can be injection molded together with the slot wall of the slot 210, or fixed to the inner wall of the slot 210 by gluing, embedding, etc.
[0071] The limiting protrusion is arranged on the slot wall of the slot 210 , and the limiting protrusion may be located on the portion of the slot wall located inside the slot 210 , or may be located on the portion of the slot wall located outside the slot 210 .
[0072] It is understandable that, in order to facilitate the insertion of the plug-in portion 110 into the slot 210, the limiting protrusion and the slot 210 are arranged on the same side as the slot opening to form an inclined surface or a curved surface. During the insertion of the plug-in portion 110 into the slot 210, the plug-in portion 110 can gradually climb along the inclined surface or the curved surface and finally pass over the limiting protrusion, so that the limiting protrusion abuts against the side of the slot opening of the plug-in portion 110 facing the slot 210. It can be seen that the setting of the inclined surface or the curved surface on the limiting protrusion is conducive to the assembly between the release assembly 100 and the mounting seat 200.
[0073] The limiting protrusion abuts against the plug-in portion 110 , which can prevent the plug-in portion 110 from moving relative to the slot 210 . Such a limiting member 230 has a simple structure and is easy to process.
[0074] In some embodiments, a height T of the limiting protrusion protruding from the slot wall of the slot 210 satisfies: 1.5 mm≤T≤0.5 mm.
[0075] If the height of the limiting protrusion protruding from the slot 210 is too high, it will hinder the plug-in part 110 from being inserted into the slot 210. If the height of the limiting protrusion protruding from the slot 210 is too low, the limiting of the plug-in part 110 is not reliable enough. When T satisfies 1.5mm≤T≤0.5mm, the plug-in part 110 can not only be inserted into the slot 210 under the action of external force applied by a person, but also prevent the plug-in part 110 from accidentally falling out of the slot 210 when no external force is applied by a person, which is beneficial to the assembly and fixation of the release assembly 100 and the mounting seat 200.
[0076] Specifically, in some embodiments, T=0.7 mm.
[0077] The limiting member 230 can also be a structure that is easy to disassemble and assemble, so that it can be disassembled before the plug-in part 110 is inserted into the slot 210, so that the plug-in part 110 can be smoothly inserted into the slot 210. After the plug-in part 110 is inserted into the slot 210, the connector can be connected to the mounting base 200.
[0078] For example, in some embodiments, the stopper 230 includes a connecting member, which is connected to the mounting seat 200 and abuts against the plug-in portion 110. For details, see Figure 1 The limiting member 230 is located at the bottom.
[0079] The connecting piece can be a common mechanical standard part such as a screw or a pin, so as to further reduce the cost of manufacturing the connecting piece. Accordingly, a hole for connecting the connecting piece can be provided on the slot wall of the slot 210 for assembling the connecting piece.
[0080] It can be seen that during the assembly process of the release assembly 100 and the mounting base 200, the connector can be flexibly removed or installed as needed, which facilitates the assembly and limiting of the release assembly 100 and the mounting base 200, and the height of the connector protruding from the groove wall of the slot 210 can be set arbitrarily, further increasing flexibility.
[0081] like Figure 3 As shown, in some embodiments, the trip module further includes a support member 300 , which is disposed between the mounting seat 200 and the trip assembly 100 and is used to limit the positions of the mounting seat 200 and the trip assembly 100 in relative directions.
[0082] The support member 300 may be integrally provided with the mounting base 200 or with any component of the release assembly 100 , or may be neither integrally provided with the mounting base 200 nor with any component of the release assembly 100 , but may be merely clamped between the mounting base 200 and the release assembly 100 .
[0083] The support member 300 can limit the relative positions of the mounting seat 200 and the release assembly 100 to prevent the mounting seat 200 and the release assembly 100 from being loosened or moved due to the loose connection.
[0084] In summary, the embodiment of the present application sets the trip assembly 100 and the mounting seat 200 in the trip module, so that for circuit breakers of different specifications, the structure of the trip assembly 100 does not need to be changed, and only the size and other structural features of the mounting seat 200 need to be changed to make it compatible with the shell frame of the circuit breaker. Therefore, when producing trip modules corresponding to circuit breakers of various specifications, only mounting seats 200 of different specifications need to be provided, and the structure of the trip assembly 100 does not need to be changed, thereby reducing the types of materials on the production line, reducing the probability of confusion between different materials, and facilitating production management.
