[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.
[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0048] The terms "including" and "having" and any variations thereof in the specification, claims, and drawings of this application are intended to cover but not exclude other elements. The word "a" or "an" does not exclude the presence of a plurality.
[0049] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase "embodiments" appearing in various positions in the specification does not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive of other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0050] The term "and / or" herein is merely a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.
[0051] The orientation terms appearing in the following description are all the directions shown in the figures and do not limit the specific structure of this application. For example, in the description of this application, terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this application.
[0052] In addition, expressions indicating directions such as the X direction, Y direction, and Z direction for explaining the operations and structures of the components in this embodiment are not absolute but relative. 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 have different interpretations to correspond to the changes.
[0053] In addition, terms such as "first" and "second" in the description and claims of this application or in 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 such features.
[0054] In the description of this application, unless otherwise specified, the meaning of "a plurality" refers to two or more (including two). Similarly, "a plurality of groups" refers to two or more groups (including two groups).
[0055] 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.

"Connected" or "coupled" in a circuit structure may refer to not only a physical connection but also an electrical connection or a signal connection. For example, it may be a direct connection, that is, a physical connection, or it may be indirectly connected through at least one intermediate element as long as the circuit is connected, and it may also be the communication inside two elements; a signal connection may refer to not only a signal connection through a circuit but also a signal connection through a media medium, such as radio waves. 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.
[0056] The circuit breaker can be connected to an external circuit for controlling the on / off of the above-mentioned external circuit. Specifically, when the external circuit is overloaded, short-circuited, or leaking, the circuit breaker can disconnect the above-mentioned external circuit to protect the safety of the circuit and personnel.
[0057] The circuit breaker provided by the embodiment of this application may include: a cover plate, a base, an operating mechanism, and a control board.
[0058] Among them, as Figure 1 and Figure 2 shown, the cover plate 1 is snapped onto the base 2, forming a receiving space between the cover plate 1 and the base 2.
[0059] Among them, as Figure 2As shown in the figure, both the control board 4 and the actuating mechanism (not shown in the figure) are arranged in the above-mentioned accommodation space. The control board 4 is used to receive and send out signals, and the actuating mechanism is used to act according to the above-mentioned signals. For example, when the control board 4 receives a first signal, the actuating mechanism performs a first action according to the first signal. Among them, the first signal can be an overload signal of an external circuit, and the first action can be a tripping action.
[0060] Furthermore, the circuit breaker 100 may further include an additional device 3. The additional device 3 is electrically connected to the control board 4 and can implement other additional functions such as a metering function or a communication function according to the signals in the control board 4.
[0061] In the related art, an installation space for the additional device 3 needs to be reserved in the accommodation cavity formed by the cover plate 1 and the base 2, that is, the volume of the original circuit breaker 100 needs to be increased, thereby increasing the production cost of the circuit breaker 100.
[0062] Based on this, the present application provides an additional device 3 and a circuit breaker 100. By arranging the additional device 3 on the cover plate 1 of the circuit breaker 100, there is no need to reserve an installation space for the additional device 3 inside the circuit breaker 100, that is, there is no need to increase the volume of the original circuit breaker 100, and the production cost of the circuit breaker 100 is reduced. The following will be specifically described in conjunction with Figures 1 - 13 for specific description.
[0063] As Figures 3 - 8 shown, the additional device 3 provided in the first aspect of the present application is applied to the circuit breaker 100. The additional device 3 includes: an installation slot 31, a function module 32, and a wire harness (not shown in the figure). The installation slot 31 is respectively provided with a first opening 311 and a second opening 312 in the first direction X. The first opening 311 faces the outside of the circuit breaker 100, and the second opening 312 faces the inside of the circuit breaker 100. Among them, the first direction X is the thickness direction of the circuit breaker 100. The function module 32 enters the installation slot 31 through the first opening 311 and is arranged in the installation slot 31. The wire harness is arranged inside the circuit breaker 100. One end of the wire harness is electrically connected to the function module 32 through the second opening 312, and the other end of the wire harness is electrically connected to the control board 4 of the circuit breaker 100. The installation slot 31 is arranged on the cover plate 1. An installation hole (not shown in the figure) is provided on the cover plate 1. The installation hole is used to communicate the inside and the outside of the circuit breaker 100. The first opening 311 corresponds to the installation hole.
[0064] Among them, the installation slot 31 has an accommodation cavity, and the function module 32 is arranged in the accommodation cavity of the installation slot 31. As Figure 3As shown, the installation position 31 is provided on the cover plate 1 of the circuit breaker 100, so that the function module 32 is installed on the cover plate 1, thereby eliminating the need to reserve additional installation space for the additional device 3 inside the circuit breaker 100, that is, without increasing the volume of the original circuit breaker 100, and reducing the production cost of the circuit breaker 100.
[0065] Among them, the function module 32 is used to control the circuit breaker 100 to implement additional functions. A circuit breaker 100 can be compatible with multiple function modules 32, and each function module 32 can implement different additional functions. In addition, a function module 32 can implement one or more additional functions, and the present application does not make specific limitations on this.
[0066] Among them, the cover plate 1 can include two opposite surfaces, which are the first surface and the second surface respectively. The first surface faces the inside of the circuit breaker 100, and the second surface faces the outside of the circuit breaker 100. As Figure 4 shown, the installation position 31 can be connected to the first surface, with one end of the installation position 31 abutting against the first surface and the other end of the installation position 31 located inside the circuit breaker 100.
[0067] Among them, as Figure 5 shown, the first opening 311 is used to communicate the inside of the installation position 31 with the inside of the circuit breaker 100. The installation hole is used to communicate the inside of the circuit breaker 100 with the outside of the circuit breaker 100. And when the installation position 31 abuts against the first surface, the first opening 311 corresponds to the installation hole opened on the cover plate 1. Based on this, when the cover plate 1 is buckled with the base 2, the function module 32 can directly enter the accommodation cavity of the installation position 31 from the outside of the circuit breaker 100. Similarly, when the cover plate 1 is buckled with the base 2, the function module 32 can also directly exit from the accommodation cavity of the installation position 31 to the outside of the circuit breaker 100. That is to say, when the cover plate 1 is buckled with the base 2, the function module 32 can be freely installed and disassembled in the installation position 31. Based on this, the operator can replace the function modules 32 with different functions at any time according to different needs. That is, function modules 32 with different functions can be installed on the same circuit breaker 100, improving the compatibility of the circuit breaker 100 and thus reducing the production cost of the circuit breaker 100.
[0068] Among them, as Figure 6 shown, the second opening 312 is used to communicate the inside of the installation position 31 with the inside of the circuit breaker 100. The function module 32 is located inside the installation position 31, and the wire harness and the control board 4 are both arranged inside the circuit breaker 100. Based on this, one end of the wire harness can be electrically connected to the function module 32 through the second opening 312, and the other end of the wire harness can be directly electrically connected to the control board 4, enabling communication between the function module 32 and the control board 4, so that the function module 32 can implement the above-mentioned additional functions according to the electrical signals transmitted by the control board 4.
[0069] In summary, for the additional device 3 provided in the present application, the functional module 32 is arranged in the installation slot 31, and the installation slot 31 is arranged on the cover plate 1 of the circuit breaker 100, so that the functional module 32 is installed on the cover plate 1. As a result, there is no need to reserve an installation space for the additional device 3 inside the circuit breaker 100, that is, there is no need to increase the volume of the original circuit breaker 100, reducing the production cost of the circuit breaker 100. Further, the installation holes opened on the cover plate 1 correspond to the first openings 311 opened on the installation slot 31, enabling the functional module 32 to be freely installed and removed within the installation slot 31. Based on this, the operator can replace the functional modules 32 with different functions at any time according to different needs. That is, functional modules 32 with different functions can be installed on the same circuit breaker 100, improving the compatibility of the circuit breaker 100 and further reducing the production cost of the circuit breaker 100.
[0070] In some embodiments, as Figure 7 and Figure 8 shown, the wire harness includes a first connection terminal 33a and a second connection terminal 33b. The first connection terminal 33a is detachably connected to the functional module 32, and the second connection terminal 33b is detachably connected to the control board 4.
[0071] Among them, a flexible connecting wire can be arranged between the first connection terminal 33a and the second connection terminal 33b for connecting the first connection terminal 33a and the second connection terminal 33b. The flexible connecting wire can be bent arbitrarily. While not occupying too much installation space inside the circuit breaker 100, the length of the flexible connecting wire can be increased to extend the maximum distance between the first connection terminal 33a and the second connection terminal 33b, facilitating the operator to pull the first connection terminal 33a to the outside of the circuit breaker 100 for connection with the functional module 32.
[0072] Among them, the first connection terminal 33a and the second connection terminal 33b can be respectively connected to two electronic devices for connecting the above two electronic devices, enabling the above two electronic devices to transmit electrical signals to each other. For example, the first connection terminal 33a is connected to the functional module 32, and the second connection terminal 33b is connected to the control board 4. The functional module 32 can implement one or some additional functions of the circuit breaker 100 according to the electrical signals in the control board 4.
[0073] Among them, the detachable connection method between the first connection terminal 33a and the functional module 32 can be a plug-in connection, enabling the functional module 32 to be freely installed or removed, reducing the cost of replacing or overhauling the functional module 32, and thus reducing the production cost of the circuit breaker 100.
[0074] Among them, the detachable connection between the second terminal 33b and the control board 4 can be a plug-in connection, enabling the wire harness to be freely installed or removed, reducing the cost of replacing or overhauling the wire harness, and thus reducing the production cost of the circuit breaker 100.
[0075] Specifically, the plug-in connection can include a male plug and a female plug. A male plug or a female plug can be provided on the first terminal 33a or the second terminal 33b. A female plug or a male plug corresponding to the first terminal 33a can be provided on the functional module 32. A female plug or a male plug corresponding to the second terminal 33b can be provided on the control board 4.
[0076] According to the description of the above embodiments, the detachable connection between the first terminal 33a of the wire harness and the functional module 32 reduces the cost of replacing or overhauling the functional module 32. The detachable connection between the second terminal 33b of the wire harness and the control board 4 reduces the cost of replacing or overhauling the wire harness. Based on the above two points, the production cost of the circuit breaker 100 can be further reduced.
[0077] In some embodiments, the mounting position 31 and the cover plate 1 are detachably connected. Alternatively, the mounting position 31 and the cover plate 1 are an integrally formed structure.
[0078] Among them, the detachable connection can include various connection methods such as screwing, riveting, or clamping. The advantages of the detachable connection can include: easy maintenance and upgrade, high flexibility, and high scalability.
[0079] Among them, the integral molding can include methods such as casting. The advantages of the integral molding can include: high stability, space saving, preventing accidental separation, and reducing production cost.
[0080] Based on the above two structures, the operator can choose according to needs.
[0081] For example, the detachable connection can be screwing. Specifically, as Figure 6 shown, two connecting pieces 313 are provided on the mounting position 31, and first threaded holes are respectively formed in the two connecting pieces 313. Two second threaded holes corresponding to the above first threaded holes are provided on the cover plate 1, so that one second threaded hole corresponds to one first threaded hole. The first threaded hole and the second threaded hole are tightened by bolts to connect the mounting position 31 to the cover plate 1.
[0082] In some embodiments, the first terminal 33a is sleeved in the mounting position 31 through the second opening 312, and the first terminal 33a is connected to the mounting position 31.
[0083] Among them, there can be various connection methods between the first terminal 33a and the mounting position 31, including but not limited to the following two.
[0084] In the first type, the first terminal 33a is bonded within the installation slot 31 to relatively fix the position between the first terminal 33a and the installation slot 31, facilitating the connection between the functional module 32 and the first terminal 33a.
[0085] In the second type, the first terminal 33a is press-fitted with the installation slot 31 through the second opening 312 to relatively fix the position between the first terminal 33a and the installation slot 31, facilitating the connection between the functional module 32 and the first terminal 33a.
[0086] Based on the above two connection methods, the first terminal 33a is connected to the installation slot 31 to relatively fix the position between the first terminal 33a and the installation slot 31, facilitating the connection between the functional module 32 and the first terminal 33a.
[0087] In some embodiments, an operating structure 321 is provided on the first end of the functional module 32. The first end is the end facing the outside of the circuit breaker 100. The operating structure 321 is used to control the functional module 32 to disengage from the installation slot.
[0088] Among them, the operating structure 321 may include the following two structures.
[0089] Structure one: The operating structure 321 may be a handle provided on the first end. An operator can apply a pulling force by holding the handle, and the pulling force drives the functional module 32 to disengage from the installation slot, facilitating the replacement or repair of the functional module 32.
[0090] Structure two is as Figure 9 shown: The operating structure 321 is a groove opened on the first end. An operator can apply a pulling force to the groove with a finger or a tool, and the pulling force drives the functional module 32 to disengage from the installation slot, facilitating the replacement or repair of the functional module 32.
[0091] Among them, the groove is opened on the first end, without adding a new structure, further reducing the production cost of the circuit breaker 100.
[0092] Based on the description of the above embodiments, an operator can apply a pulling force to the functional module 32 through the operating mechanism, and the pulling force drives the functional module 32 to disengage from the installation slot, facilitating the replacement or repair of the functional module 32.
[0093] Furthermore, the width of the groove can be greater than 3 mm to accommodate the operator's finger or the above-mentioned tool.
[0094] In some embodiments, such as Figure 10 and Figure 11As shown, when the operating structure 321 is a groove formed in the first end, a relief groove 314 is provided at the first opening 311 so that there is a gap between the functional module 32 and the inner wall of the mounting position 31.
[0095] According to the above description, the functional module 32 is arranged in the accommodating cavity of the mounting position 31. Therefore, the smaller the gap between the inner wall of the mounting position 31 and the functional module 32, the more stable the position of the functional module 32 in the mounting position 31.
[0096] Moreover, when the functional module 32 is placed in the accommodating cavity of the mounting position 31, the first end of the functional module 32 is flush with the second surface of the cover plate 1 to ensure the flatness of the appearance of the circuit breaker 100. Therefore, a relief groove 314 needs to be provided at the first opening 311 so that there is a gap between the functional module 32 and the inner wall of the mounting position 31, facilitating the operator to apply a pulling force to the groove with fingers or tools, thereby facilitating the operator to replace the functional module 32 with different functions.
[0097] Specifically, the relief groove 314 starts from the first opening 311, and the opening depth of the relief groove 314 in the first direction X is less than the distance between the first opening 311 and the second opening 312. So that between the end point of the relief groove 314 and the second opening 312, the gap between the inner wall of the mounting position 31 and the functional module 32 is still small to ensure the stable installation of the functional module 32 in the mounting position 31.
[0098] According to the description of the above embodiments, the relief groove 314 facilitates the operator to apply a pulling force to the groove with fingers or tools, thereby facilitating the operator to replace the functional module 32 with different functions.
[0099] In some embodiments, a first guiding member 315 is provided on the functional module 32, and a second guiding member 322 is provided on the mounting position 31. The first guiding member 315 cooperates with the second guiding member 322 to enable the functional module 32 to enter the first opening 311 along the first direction X.
[0100] Among them, a guiding member is a mechanical component mainly used to guide, position and restrict moving objects. The guiding member may be a pair of sliding guide rails, or two rotating shafts, etc., and the cooperation mode between them can be linear guiding, rotary guiding or compound guiding.
[0101] According to the description of the above embodiments, the first guiding member 315 and the second guiding member 322 cooperate to jointly achieve the precise guiding or positioning of the functional module 32 so that the functional module 32 can be connected to the first wiring terminal 33a.
[0102] In some embodiments, such as Figure 12 and Figure 13As shown, the second guiding member 322 is a chute opened along the first direction X, and the first guiding member 315 is a slider slidably connected in the chute. Alternatively, the second guiding member 322 is a slider opened along the first direction X, and the second guiding member 322 is a chute slidably connected to the slider.
[0103] When the second guiding member 322 is a chute opened along the first direction X and the first guiding member 315 is a slider, the slider can roll or slide in the chute to move the functional module 32 along the first direction X.
[0104] Similarly, when the second guiding member 322 is a slider opened along the first direction X and the second guiding member 322 is a chute, the chute can roll or slide on the chute block to move the functional module 32 along the first direction X.
[0105] Furthermore, the first guiding member 315 is arranged on one side of the functional module 32 along the second direction Y, and the second guiding member 322 is arranged on one side of the mounting position 31 along the second direction Y. Herein, the second direction Y and the first direction X are different directions.
[0106] When the first guiding member 315 and the second guiding member 322 are both on the same side and only on that side, the functional module 32 can only enter the mounting position 31 in one posture, thus playing an anti-fooling role during the installation process of the functional module 32.
