[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0050] The terms "comprising" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover but not exclude other contents. The word "a" or "an" does not exclude the presence of a plurality.

[0051] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0052] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0053] The directional words appearing in the following description are all directions shown in the drawings, and do not limit the specific structure of the present application. For example, in the description of the present application, the directions or positional relationships indicated by 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", etc. are 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, rather than indicating or implying 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 limiting the present application.

[0054] In addition, 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 present embodiment are not absolute but relative, and although these indications are appropriate when the components of the battery pack are in the positions shown in the figures, when these positions change, these directions should be interpreted differently to correspond to the changes.

[0055] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0056] In the description of the present application, unless otherwise specified, "plurality" means more than two (including two), and similarly, "multiple groups" means more than two groups (including two).

[0057] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a fixing member, such as a fixed connection through a screw, bolt or other fixing member; the physical connection may also be a detachable connection, such as a mutual snap connection or snap connection; the physical connection may also be an integral connection, such as welding, bonding or integral molding to form a connection for connection. The "connection" or "connection" of a circuit structure may refer to an electrical connection or a signal connection in addition to a physical connection. For example, it may be a direct connection, that is, a physical connection, or it may be an indirect connection through at least one intermediate element, as long as the circuit is connected, or it may be the internal connection of two elements; the signal connection may refer to a signal connection through a media medium, such as a radio wave, in addition to a signal connection through a circuit. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0058] like Figure 1 As shown, the present application provides a circuit breaker 100, which may include a circuit breaker body 1 and an additional device 3 arranged along a first direction X, wherein the first direction X is the direction from the circuit breaker body 1 to the additional device 3. The circuit breaker body 1 is used to perform circuit breaking protection, overload protection, and leakage protection on the power circuit. The additional device 3 is used to remotely control or remotely indicate the state of the power circuit. For example, the circuit breaker body 1 is remotely controlled by the additional device 3 to switch from a closed state to an open state.

[0059] Specifically, Figure 2 and Figure 3 As shown, the circuit breaker body 1 may include a circuit breaker system and a leakage protection system, and the circuit breaker system may include a first contact assembly 112. The circuit breaker system controls the opening and closing of the first contact assembly 112 to play a role in overload protection; the leakage protection system is linked with the circuit breaker system to control the opening and closing of the first contact assembly 112 to play a role in leakage protection. For ease of understanding, the L-pole system 11 is used to refer to the circuit breaker system, and the N-pole system 12 is used to refer to the leakage protection system.

[0060] Furthermore, if Figure 4 and 5 As shown, the circuit breaker body 1 may include a base 1c, a first cover 1a and a second cover 1b. The base 1c is used to separate the N-pole system 12 and the L-pole system 11, so that the L-pole system 11 is arranged in a receiving cavity formed by one side of the base 1c and the first cover 1a, and the N-pole system 12 is arranged in a receiving cavity formed by the other side of the base 1c and the second cover 1b.

[0061] The additional device 3 may include a connection structure 31 and a control system (not shown in the figure). The connection structure 31 is connected to the circuit breaker body 1 and linked with the L-pole system 11 in the circuit breaker body 1 to transmit the state of the first contact assembly 112 to the control system. The control system converts the state of the first contact assembly 112 into an electrical signal and transmits the electrical signal to the remote operation terminal, so that the remote operation terminal operates the connection structure 31 according to the electrical signal, so that the connection structure 31 can drive the first contact assembly 112 in the L-pole system 11 to act.

[0062] Furthermore, combined with Figure 4 and Figure 5 It can be seen that the L-pole system 11, the N-pole system 12 and the additional device 3 are arranged in sequence along the first direction X, that is, the N-pole system 12 is located between the L-pole system 11 and the additional device 3. Therefore, the connection structure 31 needs to pass through the N-pole system 12 to connect with the L-pole system 11.

[0063] Combination Figure 2 and Figure 3 It can be seen that the N-pole system 12 and the L-pole system 11 are both arranged on the left side of the circuit breaker body 1; Figure 4 It can be seen that the connection structure 31 is connected to the circuit breaker body 1 from the left side thereof. That is, the N-pole system 12 disposed on the left side of the circuit breaker body 1 will hinder the linkage between the additional device 3 and the L-pole system 11, so that the circuit breaker 100 cannot have the additional function of the additional device 3.

[0064] Based on this, when the N-pole system 12 is set on the left side of the circuit breaker body 1, the present application proposes a linkage part 2 for connecting the L-pole system 11 and the additional device 3, so as to realize the linkage between the L-pole system 11 and the additional device 3, so that the circuit breaker 100 can have the additional functions in the additional device 3.

[0065] The linkage member 2 provided in the embodiment of the present application may include a first connection portion 21 and a second connection portion 22, wherein the first connection portion 21 is one end of the linkage member 2 in the first direction X, and the first direction X is the direction in which the circuit breaker body 1 faces the additional device 3. The second connection portion 22 is the other end of the linkage member 2 in the first direction X. The circuit breaker body 1 includes an L-pole system 11, in which a first unlocking assembly 111 is provided. The additional device 3 is provided at one side of the circuit breaker body 1 along the first direction X, and a connecting structure 31 is provided in the additional device 3. The first connection portion 21 is connected to the first unlocking assembly 111; and the second connection portion 22 is connected to the connecting structure 31.

[0066] Combination Figure 2 , Figure 6 and Figure 7 As shown, the first connection portion 21 may be a structural member for connecting the L-pole system 11. Figure 4 and Figure 6 It can be known that the second connection part 22 can be a structural member for connecting the connection structure 31. The first connection part 21 and the second connection part 22 are the two ends of the linkage part 2 respectively. The first connection part 21 can be connected to the second connection part 22, and the connection method can include welding, screw connection or clamping. The first connection part 21 and the second connection part 22 can also be integrally formed. There is no restriction on the connection relationship between the first connection part 21 and the second connection part 22.

[0067] Specifically, Figure 2 As shown, the first unlocking assembly 111 may include a first lock buckle 111a and a first jump buckle 111b. The locking or unlocking between the first lock buckle 111a and the first jump buckle 111b can be used to control the state of the first contact assembly 112 in the L-pole system 11. It should be noted here that when the first lock buckle 111a rotates to the first position, the first lock buckle 111a and the first jump buckle 111b are locked; when the first lock buckle 111a rotates to the second position, the first lock buckle 111a and the first jump buckle 111b are unlocked.

[0068] Exemplarily, when the first lock buckle 111a and the first jump buckle 111b are locked, the first contact assembly 112 can be kept in a closed state. When the first lock buckle 111a and the first jump buckle 111b are unlocked, the first contact assembly 112 can be switched from a closed state to an open state.

[0069] Furthermore, if Figure 3 As shown, when the N-pole system 12 is arranged on the left side of the circuit breaker body 1, there is a gap between the N-pole system 12 and the left side frame of the circuit breaker body 1. Figure 7 It can be seen that the first connection part 21 passes through the above gap along the first direction X, so that the first connection part 21 is connected to the first lock buckle 111a, so that the first connection part 21 and the first lock buckle 111a rotate synchronously, thereby realizing the linkage of the linkage part 2 and the L-pole system 11.

[0070] Furthermore, combined with Figure 3 and Figure 6 It can be seen that the second connecting portion 22 is the other end of the linkage member 2 in the first direction X, and as shown in FIG. Figure 4 As shown, the additional device 3 is arranged on one side of the circuit breaker body 1 along the first direction X, so that the second connection part 22 is connected to the connection structure 31 of the additional device 3, so that the second connection part 22 and the connection structure 31 rotate synchronously, thereby realizing the linkage of the linkage member 2 and the additional device 3.

[0071] In summary, the linkage member 2, the L-pole system 11 and the additional device 3 are linked. That is, when the N-pole system 12 is arranged on the left side of the circuit breaker body 1, the additional device 3 can control the locking or unlocking of the first unlocking component 111 in the L-pole system 11 through the linkage member 2, thereby realizing the remote control of the closing or opening of the first contact through the additional device 3.

[0072] The linkage member 2 provided in the embodiment of the present application includes a first connection portion 21 and a second connection portion 22. The first connection portion 21 is connected to the first unlocking component 111 of the L-pole system 11, so that the linkage member 2 is linked to the L-pole system 11. The second connection portion 22 of the linkage member 2 is connected to the connection structure 31 of the additional device 3, so that the linkage member 2 is linked to the additional device 3. In addition, the first connection portion 21 is one end of the linkage member 2, and the second connection portion 22 is the other end of the linkage member 2, so the first connection portion 21 and the second connection portion 22 are linked, so that the linkage member 2, the L-pole system 11 and the additional device 3 are linked, so that the circuit breaker 100 can have the additional functions in the additional device 3.

[0073] In some embodiments, a first mounting groove (not shown) is provided on the first unlocking assembly 111. The first connecting portion 21 is a first connecting rod extending along the first direction X. One end of the first connecting rod is sleeved in the first mounting groove.

[0074] Specifically, Figure 6 As shown, the first direction X is the length direction of the first connecting rod, and the first connecting rod is sleeved in the first mounting groove, so that the first connecting rod is clamped in the first mounting groove, so that the first connecting rod can rotate synchronously with the first unlocking component 111, thereby realizing the linkage of the linkage member 2 and the L-pole system 11. Specifically, the connection mode of the first connecting rod and the first mounting groove belongs to the hole-shaft connection, and the advantages of the hole-shaft connection include: simple and easy to use, stable and reliable, and high transmission efficiency.

[0075] Furthermore, if Figure 3 As shown, the gap direction between the N-pole system 12 and the left side frame of the circuit breaker body 1 is the second direction Y. Figure 3 and Figure 6 It can be seen that the width of the first connecting rod in the second direction Y is small, so that the first connecting rod can easily pass through the above gap, which facilitates the connection between the first connecting portion 21 and the first unlocking component 111.

[0076] Based on the description of the above embodiment, the first unlocking assembly 111 is provided with a first mounting groove, and the first connecting portion 21 is a first connecting rod extending along the first direction X, so as to facilitate the connection between the first connecting portion 21 and the first unlocking assembly 111. When one end of the first connecting rod is sleeved in the first mounting groove, the first connecting rod and the first mounting groove are mutually engaged, so that the first connecting rod and the first unlocking assembly 111 rotate synchronously, thereby realizing the linkage of the linkage member 2 and the L-pole system 11.

[0077] In some embodiments, Figure 7 and Figure 8 As shown, a reset member 14 is provided between the first connection portion 21 and the first unlocking assembly 111. A first mounting groove (not shown in the figure) is provided on the first unlocking assembly 111. The first connection portion 21 is a first connecting rod extending along the first direction X. A second mounting groove 141 is provided on the side of the reset member 14 close to the first connection portion 21, and a protrusion structure (not shown in the figure) is provided on the side of the reset member 14 close to the first unlocking assembly 111. One end of the first connecting rod is sleeved in the second mounting groove 141. The protrusion structure is sleeved in the first mounting groove.

[0078] Specifically, a reset member 14 is added between the first connection portion 21 and the first unlocking assembly 111, and a protrusion structure adapted to the first mounting groove is provided on one side of the reset member 14 close to the first unlocking assembly 111, so that the protrusion structure is clamped in the first mounting groove, so that the reset member 14 can rotate synchronously with the first unlocking assembly 111, thereby realizing the linkage of the reset member 14 and the L-pole system 11. Specifically, the connection mode of the reset member 14 and the L-pole system 11 belongs to a hole-shaft connection, and the benefits of the hole-shaft connection are mentioned in the above content and will not be repeated here.

[0079] Furthermore, a second mounting groove 141 adapted to the first connecting portion 21 is provided on one side of the reset member 14 close to the first connecting portion 21, so that the first connecting portion 21 is snapped into the second mounting groove 141, so that the first connecting portion 21 can rotate synchronously with the reset member 14, thereby realizing the linkage of the linkage member 2 and the reset member 14. Specifically, the connection mode between the linkage member 2 and the reset member 14 also belongs to the hole-shaft connection, and the benefits of the hole-shaft connection are mentioned in the above content, which will not be repeated here.

[0080] In summary, the linkage member 2 , the reset member 14 and the L-pole system 11 are linked.

[0081] Furthermore, the reset member 14 is used to control the reset of the first contact assembly 112 in the L-pole system 11. Reset can be understood as the first contact assembly 112 being restored from an open state to a closed state. When the circuit breaker body 1 is in an open state due to an overload short circuit, the reset member 14 can convert the first contact assembly 112 to a closed state to connect the current in the circuit breaker body 1 so that the circuit breaker body 1 can be put into use again. Therefore, a reset member 14 is added between the L-pole system 11 and the linkage member 2 so that the circuit breaker 100 has a reset function.

[0082] Based on the description of the above embodiment, a second mounting groove 141 is provided on a side of the reset member 14 close to the first connection portion 21, and the first connection portion 21 is sleeved in the second mounting groove 141, so that the first connection portion 21 is clamped in the second mounting groove 141, so that the linkage member 2 is linked with the reset member 14. A protrusion structure is provided on a side of the reset member 14 close to the first unlocking component 111, and the protrusion structure is sleeved in the first mounting groove, so that the protrusion structure is clamped in the first mounting groove, so that the reset member 14 is linked with the L-pole system 11. The linkage member 2, the reset member 14 and the L-pole system 11 are linked, so that the circuit breaker 100 has a reset function without affecting the linkage between the linkage member 2 and the L-pole system 11.

[0083] In some embodiments, Figure 6 As shown, the end of the second connecting portion 22 facing the additional device 3 is provided with a third mounting groove 221. Figure 4 As shown, the connection structure 31 is a second connection rod extending along the first direction X. One end of the second connection rod facing the circuit breaker body 1 is sleeved in the third installation groove 221 .

[0084] Specifically, combined Figure 4 and Figure 6 It can be seen that the first direction X is the length direction of the second connecting rod, and the second connecting rod is sleeved in the third mounting groove 221, so that the second connecting rod is clamped in the third mounting groove 221, so that the second connecting rod can rotate synchronously with the second connecting portion 22, thereby realizing the linkage of the linkage member 2 and the additional device 3. Specifically, the connection mode of the second connecting rod and the third mounting groove 221 belongs to the hole-shaft connection, and the benefits of the hole-shaft connection are mentioned in the above content, which will not be repeated here.

[0085] Based on the description of the above embodiment, a third mounting groove 221 is provided at one end of the second connecting portion 22 facing the additional device 3. The connecting structure 31 is a second connecting rod extending along the first direction X. The second connecting rod is sleeved in the third mounting groove 221, so that the second connecting rod is clamped in the third mounting groove 221, so that the second connecting rod can rotate synchronously with the second connecting portion 22, thereby realizing the linkage of the linkage member 2 and the additional device 3.

[0086] In some embodiments, Figure 5 As shown, the circuit breaker body 1 includes a base 1c, a first cover 1a and a second cover 1b. The second cover 1b is provided with a through hole 15 adapted to the third mounting groove 221. Figure 5 and Figure 6It can be seen that the position of the through hole 15 on the second cover 1b corresponds to the position of the third mounting groove 221, so that the second connecting rod in the attachment 3 can pass through the through hole 15 and be clamped in the third mounting groove 221. In addition, the cross section of the through hole 15 in the first direction X is similar to the cross section of the third mounting groove 221 in the first direction X. Exemplarily, the cross section of the through hole 15 in the first direction X and the cross section of the third mounting groove 221 in the first direction X are both arc-shaped, so that the second connecting rod can rotate in the through hole 15 and the third mounting groove 221, thereby realizing the linkage of the linkage member 2 and the attachment 3.

[0087] In some embodiments, the circuit breaker body 1 includes an N-pole system 12, in which a second unlocking assembly 121 is disposed. The linkage member 2 is disposed on a rotation track of the second unlocking assembly 121. When the second unlocking assembly 121 is unlocked and rotated, the linkage member 2 is driven to rotate.

[0088] Specifically, Figure 3 As shown, the second unlocking assembly 121 may include a second lock buckle 121b, a second trip buckle 121a and a rotating seat 121c. Exemplarily, the second connecting portion 22 in the linkage member 2 may be arranged on the rotation track of the rotating seat 121c. When the N-pole system 12 senses a leakage current, the rotating seat 121c rotates. Since the second connecting portion 22 is arranged on the rotation track of the rotating seat 121c, the rotating seat 121c pushes the linkage member 2 to rotate together when the rotating seat 121c rotates. The rotation of the linkage member 2 drives the first lock buckle 111a in the L-pole system 11 to rotate, so that the first lock buckle 111a and the first trip buckle 111b are unlocked, so that the first contact assembly 112 can be converted from a closed state to an open state, thereby realizing leakage protection for the circuit breaker body 1.

[0089] In summary, the linkage member 2, the N-pole system 12 and the L-pole system 11 are linked, so that when the N-pole system 12 senses the leakage current, the first contact assembly 112 in the L-pole system 11 can be disconnected in time. Further, the linkage member 2 is linked with the additional device 3. Therefore, the linkage member 2, the additional device 3, the N-pole system 12 and the L-pole system 11 are linked, so that the additional device 3 can remotely control the leakage protection function of the circuit breaker body 1.

[0090] Based on the description of the above embodiment, the N-pole system 12 in the circuit breaker body 1 is provided with a second unlocking component 121, and the linkage member 2 is arranged on the rotation track of the second unlocking component 121. When the second unlocking component 121 is unlocked and rotated, the linkage member 2 is driven to rotate, so that the linkage between the linkage member 2, the additional device 3, the N-pole system 12 and the L-pole system 11 can be realized, so that the additional device 3 can remotely control the leakage protection function of the circuit breaker body 1.

[0091] In some embodiments, Fig. 9 As shown, the circuit breaker body 1 includes a transmission rod 13. The linkage member 2 includes a third connection portion 23. The third connection portion 23 is connected to the transmission rod 13.

[0092] A third connection part 23 is added to the linkage member 2, so that the third connection part 23 is connected to the transmission rod 13. At this time, the linkage member 2 and the circuit breaker body 1 include a first connection and a second connection. Among them, the first connection is the connection between the first connection part 21 and the first unlocking component 111, and the second connection is the connection between the third connection part 23 and the transmission rod 13. The two connections simultaneously limit the position of the linkage member 2, so that when the linkage member 2 and the second unlocking component 121 rotate synchronously, the linkage member 2 will not shake, thereby improving the stability of the linkage member 2.

[0093] Further, the transmission rod 13 is a structural member connecting the N-pole system 12 and the L-pole system 11 , that is, the transmission rod 13 may include a first portion located in the N-pole system 12 and a second portion located in the L-pole system 11 .

[0094] Specifically, the third connection part 23 can be connected to the first part. Since the N-pole system 12 is located between the L-pole system 11 and the additional device 3, and the first connection part 21 is connected to the L-pole system 11, and the second connection part 22 is connected to the additional device 3, the third connection part 23 can be arranged between the first connection part 21 and the second connection part 22 to achieve the connection between the third connection part 23 and the first part.

[0095] Based on the description of the above embodiment, the third connecting portion 23 on the linkage member 2 is connected to the transmission rod 13 of the circuit breaker body 1, so that when the linkage member 2 and the second unlocking assembly 121 rotate synchronously, the linkage member 2 will not shake, thereby improving the stability of the linkage member 2.

[0096] In some embodiments, in combination Fig. 9 and Fig.10 It can be known that the third connecting portion 23 is a connecting piece extending toward the transmission rod 13. A connecting hole 231 is provided on the connecting piece. The connecting hole 231 is sleeved on the transmission rod 13.

[0097] The N-pole system 12 may include a second contact assembly 122 and a second unlocking assembly 121 . The second contact assembly 122 is disposed at one side of the second unlocking assembly 121 along the first direction X, and a limited interval is provided between the second contact assembly 122 and the second unlocking assembly 121 .

[0098] The third connecting portion 23 is a connecting piece extending toward the transmission rod 13 so that the connecting piece is connected to the transmission rod 13. The connecting piece is a thin sheet structure, that is, the thickness is small. Specifically, the thickness of the connecting piece is the dimension in the first direction X, so that the connecting piece can be arranged in the interval between the second contact assembly 122 and the second unlocking assembly 121.

[0099] Furthermore, a connecting hole 231 is provided on the connecting plate, and the connecting hole 231 is sleeved on the transmission rod 13, so that the connecting plate can rotate on the transmission rod 13, thereby avoiding affecting the synchronous rotation of the linkage member 2 and the second unlocking component 121. Specifically, the connection mode of the connecting hole 231 and the transmission rod 13 belongs to a hole-shaft connection, and the benefits of the hole-shaft connection are mentioned in the above content and will not be repeated here.

[0100] Based on the description of the above embodiment, the third connecting portion 23 is a connecting piece extending toward the transmission rod 13 so that the connecting piece is connected to the transmission rod 13. The connecting piece is sleeved on the transmission rod 13 through the connecting hole 231, so that the connecting piece can rotate on the transmission rod 13, thereby avoiding affecting the synchronous rotation of the linkage member 2 and the second unlocking assembly 121.

[0101] In some embodiments, Fig.10 As shown, an opening 222 is provided on the groove wall of the third installation groove 221 .

[0102] The N-pole system 12 may include several components. Since the installation space of the N-pole system 12 in the circuit breaker body 1 is limited, the above components may interfere with the second connecting portion 22 of the linkage member 2 .

[0103] Based on the description of the above embodiment, an opening 222 is provided on the groove wall of the third installation groove 221 for avoiding the N-pole system 12 and preventing interference between the N-pole system 12 and the second connecting portion 22 of the linkage member 2 .

[0104] In some embodiments, Fig.10 As shown, a limiting boss 223 is provided at one end of the opening 222 .

[0105] Based on the description of the above embodiment, a limiting boss 223 is provided at one end of the opening 222 for limiting the connecting structure 31 of the additional device 3 to prevent the connecting structure 31 from escaping from the second mounting groove 141 .
