Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an operating mechanism and a circuit breaker. Background Art

[0002] Circuit breakers are important switching devices in power organizations, which can close, carry and disconnect current in the circuit. When overload, short circuit and other faults occur in the system, the circuit breaker can disconnect the circuit by opening the switch to prevent the fault from expanding. When the above fault is eliminated, the circuit breaker can connect the circuit by closing the switch. In addition, according to the identification structure in the circuit breaker, the operator can judge the current on-off status of the circuit.

[0003] In the related art, there are many parts in the circuit breaker, the processing and assembly processes are relatively complicated, the assembly efficiency is low, and the relatively scattered arrangement of the parts will occupy more assembly space. Utility Model Content

[0004] The present application provides an operating mechanism and a circuit breaker, which saves assembly space in the circuit breaker.

[0005] In a first aspect, the present application provides an operating mechanism, including: a handle, an energy storage component and an indication window. The handle is connected to the contact assembly, and the handle rotates to drive the contact assembly to perform an opening action or a closing action. The energy storage component is connected to the handle, and when the contact assembly performs an opening action or a closing action, the energy storage component rotates together with the handle. The energy storage component abuts against the contact assembly, and the energy storage component is used to control the automatic closing of the contact assembly. The indication window is arranged on the housing. A first indication portion is provided on the energy storage component. When the contact assembly performs an opening action, the first indication portion can be seen in the indication window.

[0006] According to the first aspect, the present application connects the handle to the contact assembly, and allows part of the handle to pass through the indication window, so that the handle can be used to operate the opening and closing of the circuit breaker, and an energy storage component is provided on the handle to improve the speed and sensitivity of closing the circuit breaker. A first indication portion is provided on the energy storage component. When the contact assembly performs an opening action, the first indication portion can be seen in the indication window, and there is no need to provide an additional indication structure in the circuit breaker, thus saving assembly space in the circuit breaker.

[0007] Furthermore, there is no need to set an additional indication structure in the circuit breaker, and the steps of setting an indication structure separately in the circuit breaker can be reduced, thereby reducing the manufacturing cost of the circuit breaker. Furthermore, the first indication part is set on the energy storage component, and the energy storage component can store energy, and the effect of opening indication is increased, so that the energy storage component can achieve a multiplexing effect.

[0008] In a possible design, the handle includes a first rotating portion and an operating portion. The operating portion is connected to the first rotating portion, and the first rotating portion is divided into a first side and a second side opposite to each other. A second indicating portion is provided on the first side. The first indicating portion is connected to the second side, and the first indicating portion covers the second side. The operating portion is sleeved in the indicating window. When the contact assembly performs a closing action, the second indicating portion can be seen in the indicating window.

[0009] Based on the description of the above embodiment, a second indicator is provided on the first side of the first rotating part. When the contact assembly performs a closing action, the handle rotates toward the second side, and the second indicator can be seen in the indicator window. On the basis of being able to control closing and opening, the handle has an additional closing indicator effect, so that the handle can achieve a multiplexing effect.

[0010] In a possible design, the first indicating portion and the second indicating portion have different colors.

[0011] Based on the description of the above embodiment, setting the first indicator and the second indicator to different colors is helpful to distinguish whether the circuit breaker is in the closed state or the open state.

[0012] In a possible design, a first mark is provided on the first indicating portion, and a second mark is provided on the second indicating portion.

[0013] Based on the description of the above embodiment, a first mark is set on the first indicator part, and a second mark is set on the second indicator part, which is helpful to distinguish whether the circuit breaker is in the closed state or the open state.

[0014] In a possible design, a third mark is provided on the first indicator portion, and the third mark is farther away from the operating portion than the first mark. When the contact assembly completes the opening action, the third mark can be seen in the indicator window.

[0015] Based on the description of the above embodiment, since the contact assembly may not be completely opened during the opening process, an arc still exists between the moving contact and the static contact. Based on this, the present application sets a third mark on the first indicator portion. When the contact assembly completes the opening action, the third mark can be seen in the indicator window. It is convenient for the operator to judge whether the contact assembly is completely opened, and avoid damage to the contact assembly due to the arc.

[0016] In a possible design, the energy storage component and the first indicator part are an integrally formed structure. Alternatively, the energy storage component and the first indicator part are separate structures.

[0017] Based on the description of the above embodiments, when the manufacturing method of integrally forming the energy storage component and the first indicator portion is selected, the stability of the structure is increased. When the manufacturing method of separately forming the energy storage component and the first indicator portion and then assembling them is selected, the energy storage component and the first indicator portion can be repaired or replaced separately, saving repair costs.

[0018] In a possible design, the second side is provided with a mounting groove, and the first indicating portion is provided with a protruding structure, which is embedded in the mounting groove, so that the first indicating portion rotates together with the second side.

[0019] Based on the description of the above embodiments, since the circuit breaker is generally small in size and has limited internal space, the present application provides a mounting groove on the second side. The first indicator portion is provided with a protruding structure. When the protruding structure is embedded in the mounting groove, the volume occupied by the first indicator portion inside the circuit breaker is reduced.

[0020] In a possible design, a first torsion spring is sleeved on the handle. One end of the first torsion spring is fixed in the housing, and the other end of the first torsion spring abuts against the energy storage component. When the contact assembly completes the closing action, the first torsion spring is used to reset the energy storage component.

[0021] Based on the description of the above embodiment, in the prior art, there is no abutment relationship between the first torsion spring and the energy storage component. The energy storage component needs to be reset by a reset structure. Based on this, the present application fixes one end of the first torsion spring in the housing, and abuts the other end of the first torsion spring against the energy storage component. By releasing energy after the first torsion spring stores energy, the energy storage component can be reset when the contact assembly completes the closing action. In this way, there is no need to reset the energy storage component by setting a reset structure, which saves production costs and saves assembly space in the circuit breaker.

[0022] In a possible design, the housing includes a base. A limit block is provided on the base. The limit block abuts against the first torsion spring to prevent the first torsion spring from moving toward the base. A guide slope is provided on the energy storage component. The first torsion spring abuts against the energy storage component along the guide slope.

[0023] Based on the description of the above embodiment, the energy storage component is provided with a guide slope, and the first torsion spring abuts against the energy storage component along the guide slope, so that the energy storage component is fixed on the base, and the connection between the energy storage component and the first torsion spring is realized, so that the energy storage component is reset through the first torsion spring.

[0024] In a second aspect, the present application provides a circuit breaker, comprising: a housing, a contact assembly, and the operating mechanism mentioned in the first aspect.

[0025] The beneficial effects of the circuit breaker provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, which will not be described in detail here.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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).

[0055] 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 ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0057] like Figure 1 and Figure 2 As shown, the present application provides a circuit breaker 100, which includes: a housing 5, a contact assembly 6 and an operating mechanism.

[0058] like Figure 3 As shown, the housing 5 includes a base 51 and a cover body. The base 51 and the cover body are covered to form an installation space. The contact assembly 6 and the operating mechanism are both arranged in the installation space.

[0059] The contact assembly 6 is one of the important components in the circuit breaker 100. The opening and closing of the contact assembly 6 can control whether the current in the circuit breaker 100 is conducting.

[0060] The operating mechanism is linked with the contact assembly 6. The operating mechanism includes a handle 1. When the current in the circuit breaker 100 needs to be turned on or off, the handle 1 is turned to drive the contact assembly 6 to close or open, thereby controlling the current in the circuit breaker 100 to be turned on or off.

[0061] The operating mechanism provided by the present application is explained in detail below with reference to the accompanying drawings.

[0062] The present application provides an operating mechanism, such as Figure 1 and Figure 2 As shown, the operating mechanism includes: a handle 1, an energy storage component 2 and an indication window 3. The handle 1 is connected to the contact assembly 6. The handle 1 rotates to drive the contact assembly 6 to perform an opening action or a closing action. The energy storage component 2 is connected to the handle 1. When the contact assembly 6 performs an opening action or a closing action, the energy storage component 2 rotates together with the handle 1. The energy storage component 2 abuts against the contact assembly 6, and the energy storage component 2 is used to control the contact assembly 6 to automatically close. The indication window 3 is arranged on the housing 5. A first indication portion 21 is provided on the energy storage component 2. When the contact assembly 6 performs an opening action, the first indication portion 21 can be seen in the indication window 3.

[0063] The indication window 3 is a slot structure provided on the base 51, and the indication window 3 may be circular or square, etc. The indication window 3 may be integrally formed with the base 51 when the base 51 is formed, or the indication window 3 may be provided by cutting or carving after the base 51 is formed.

[0064] A portion of the handle 1 is disposed in the installation space of the housing 5, and another portion of the handle 1 is disposed outside the housing 5 through the indication window 3. The indication window 3 needs to be larger than the portion of the handle 1 disposed outside the housing 5 so that the handle 1 can operate normally.

[0065] The energy storage component 2 is disposed in the installation space of the housing 5, and the energy storage component 2 is detachably connected to the handle 1. The energy storage component 2 is provided with a first indicating portion 21, and the first indicating portion 21 is prism-shaped or plate-shaped. The first indicating portion 21 fits with the portion of the handle 1 disposed in the housing 5, so that the operation of the handle 1 is not affected by the setting of the first indicating portion 21. The first indicating portion 21 can be integrally formed with the energy storage component 2, or the first indicating portion 21 can be separately formed with the energy storage component 2 and then assembled.

[0066] The handle 1 is connected to the contact support through a connector 7. When the circuit breaker 100 needs to be turned on, Figure 4 The handle 1 is rotated in the first direction X shown, and the handle 1 drives the connecting member 7 and the energy storage member 2 to rotate. Figure 5 and Figure 6 As shown, the energy storage member 2 generates friction force after contacting the contact support during the rotation process, so that the energy storage member 2 stores energy. Continue to rotate the handle 1, and when the energy storage member 2 separates from the contact support, the moving contact and the static contact in the contact assembly 6 are closed. The first direction X is the closing direction.

[0067] When the circuit breaker 100 needs to be disconnected, Figure 5 The handle 1 is rotated in the second direction Y shown, and the handle 1 drives the connecting member 7 to rotate, and the connecting member 7 drives the moving contact and the static contact in the contact assembly 6 to separate. Figure 7 As shown, the handle 1 drives the energy storage component 2 to rotate, so that the first indicating portion 21 in the energy storage component 2 can be seen in the indicating window 3 .

[0068] In summary, the present application connects the handle 1 to the contact assembly 6, and allows part of the handle 1 to pass through the indication window 3, so that the handle 1 can be used to operate the opening and closing of the circuit breaker 100. The energy storage component 2 is arranged on the handle 1, which improves the closing speed and sensitivity of the circuit breaker 100. The energy storage component 2 is provided with a first indication portion 21. When the contact assembly 6 performs an opening action, the first indication portion 21 can be seen in the indication window 3, and there is no need to set an additional indication structure in the circuit breaker 100, thus saving the assembly space in the circuit breaker 100.

[0069] Furthermore, there is no need to additionally set an indication structure in the circuit breaker 100, and the steps of separately setting an indication structure in the circuit breaker 100 can be reduced, thereby reducing the manufacturing cost of the circuit breaker 100. Furthermore, the first indication portion 21 is set on the energy storage component 2, and the energy storage component 2 can store energy, and the effect of opening indication is added, so that the energy storage component 2 can achieve a multiplexing effect.

[0070] In some embodiments, Figure 8 and Fig. 9 As shown, the handle 1 includes a first rotating portion 11 and an operating portion 12. The operating portion 12 is connected to the first rotating portion 11, dividing the first rotating portion 11 into a first side and a second side opposite to each other. The first indicating portion 21 is connected to the second side, and the first indicating portion 21 covers the second side. The operating portion 12 is sleeved in the indicating window 3. When the contact assembly 6 performs a closing action, the indicating window 3 can see the first side.

[0071] The first rotating portion 11 may be cylindrical or semi-cylindrical. The first rotating portion 11 is disposed in the installation space of the housing 5.

[0072] The operating portion 12 is disposed outside the housing 5. The operating portion 12 may be prism-shaped or cylindrical-shaped, etc., and may be provided with anti-slip stripes to prevent the handle 1 from slipping during operation. The operating portion 12 and the first rotating portion 11 may be integrally formed, or the operating portion 12 and the first rotating portion 11 may be separately formed and then assembled.

[0073] When the manufacturing method of integrally forming the first rotating part 11 and the operating part 12 is selected, the transmission stability of the handle 1 is increased. When the manufacturing method of separately forming the operating part 12 and the first rotating part 11 and then assembling them is selected, since the operating part 12 is arranged outside the housing 5, the operating part 12 may be damaged by external force. In this way, the operating part 12 can be replaced separately, saving maintenance costs.

[0074] The first side of the first rotating portion 11 is a side away from the energy storage component 2 , and the second side of the first rotating portion 11 is a side close to the energy storage component 2 .

[0075] When the contact assembly 6 performs a closing action, the operating part 12 rotates toward the second side, so that the second side rotates into the installation space of the housing 5, and the first side rotates to the position of the indication window 3, so that the operator can see the second indication part 13 set on the first side from the indication window 3.

[0076] In summary, the second indicating portion 13 is provided on the first side of the first rotating portion 11. When the contact assembly 6 performs a closing action, the handle 1 rotates toward the second side, and the second indicating portion 13 can be seen in the indicating window 3. The handle 1 can control the closing and opening of the switch, and the closing indication effect is added, so that the handle 1 can achieve a multiplexing effect.

[0077] There are many ways to configure the first indicating portion 21 and the second indicating portion 13 , and only two of them are described in detail below.

[0078] In a first configuration, the first indicator portion 21 and the second indicator portion 13 have different colors.

[0079] For example, the first indicator portion 21 may be red or yellow, and the second indicator portion 13 may be green or blue.

[0080] When the first indicator portion 21 is red, the second indicator portion 13 is green.

[0081] When the first indicator portion 21 is yellow, the second indicator portion 13 is blue.

[0082] When the first setting mode is selected, the first indicator portion 21 and the second indicator portion 13 are set to different colors, which is helpful for distinguishing whether the circuit breaker 100 is in a closed state or an open state.

[0083] In a second configuration, a first mark is disposed on the first indicating portion 21 , and a second mark is disposed on the second indicating portion 13 .

[0084] When the contact assembly 6 performs an opening action, a first mark can be seen in the indication window 3 .

[0085] When the contact assembly 6 performs a closing action, a second mark can be seen in the indicator window 3 .

[0086] For example, the first mark may be a circular groove or a cross-shaped groove. The second mark may be a circular protrusion or a cross-shaped protrusion.

[0087] When the first indicator is a circular groove, the second indicator portion 13 is a circular protrusion.

[0088] When the first indicating portion 21 is a cross-shaped groove, the second indicating portion 13 is a cross-shaped protrusion.

[0089] When the second setting mode is selected, a first mark is set on the first indicator portion 21, and a second mark is set on the second indicator portion 13. This is helpful to distinguish whether the circuit breaker 100 is in a closed state or an open state.

[0090] Furthermore, a third mark may be provided on the first indicator portion 21, and the third mark is farther away from the operating portion 12 than the first mark. When the contact assembly 6 completes the opening action, the third mark can be seen in the indicator window 3.

[0091] The third mark is arranged between the first mark and the energy storage component 2 .

[0092] For example, the third mark may be a triangular groove or a triangular protrusion.

[0093] Since the contact assembly 6 may not be completely opened during the opening process, an arc still exists between the moving contact and the static contact. Based on this, the present application sets a third mark on the first indicator 21. When the contact assembly 6 completes the opening action, the third mark can be seen in the indicator window 3. It is convenient for the operator to judge whether the contact assembly 6 is completely opened, and avoid damage to the contact assembly 6 due to the arc.

[0094] In some embodiments, the second side may be provided with a mounting groove. The first indicator portion 21 may be provided with a protruding structure. The protruding structure may be embedded in the mounting groove, so that the first indicator portion 21 rotates together with the second side.

[0095] The mounting groove may be a groove structure provided on the second side. The mounting groove may be integrally formed with the first rotating part 11 when the first rotating part 11 is formed. The mounting groove may also be provided by cutting or carving after the first rotating part 11 is formed.

[0096] The protruding structure may be a block structure provided on the first indicating portion 21 . The protruding structure may be integrally formed with the first indicating portion 21 . The protruding structure may also be separately formed with the first indicating portion 21 and then assembled.

[0097] Since the circuit breaker 100 is generally small in size and has limited internal space, the present application provides a mounting groove on the second side. The first indicator 21 is provided with a protruding structure. When the protruding structure is embedded in the mounting groove, the volume occupied by the first indicator 21 inside the circuit breaker 100 is reduced.

[0098] In some embodiments, the protrusion structure may be disposed on the second side. The mounting groove may be disposed on the first indicating portion 21. When the protrusion structure is embedded in the mounting groove, the first indicating portion 21 may rotate together with the second side.

[0099] In some embodiments, Figure 3 and Fig.10 As shown, the handle 1 is sleeved with a first torsion spring 4. One end of the first torsion spring 4 is fixed in the housing 5, and the other end of the first torsion spring 4 abuts against the energy storage member 2. When the contact assembly 6 completes the closing action, the first torsion spring 4 is used to reset the energy storage member 2.

[0100] The first torsion spring 4 is detachably connected to the handle 1. One end of the first torsion spring 4 can be fixed in the housing 5 by welding or bonding.

[0101] When the contact assembly 6 performs the closing action, the handle 1 rotates, and the handle 1 drives the energy storage component 2 to rotate. One end of the first torsion spring 4 is fixed in the housing 5, and the other end of the first torsion spring 4 abuts against the energy storage component 2, and rotates with the energy storage component 2. At this time, the first torsion spring 4 is stretched with the closing action, so that the first torsion spring 4 has dynamic potential energy.

[0102] When the contact assembly 6 completes the closing action, the handle 1 and the energy storage member 2 stop rotating. The kinetic potential energy of the first torsion spring 4 causes the first torsion spring 4 to move toward the initial position of the energy storage member 2 until the first torsion spring 4 returns to its initial state. The other end of the first torsion spring 4 abuts against the energy storage member 2, driving the energy storage member 2 to move to the initial position of the energy storage member 2, completing the resetting of the energy storage member 2.

[0103] In the prior art, there is no abutment relationship between the first torsion spring 4 and the energy storage component 2. The energy storage component 2 needs to be reset by a reset structure. Based on this, the present application fixes one end of the first torsion spring 4 in the housing 5, and abuts the other end of the first torsion spring 4 on the energy storage component 2. By releasing energy after the first torsion spring 4 stores energy, the energy storage component 2 can be reset when the contact assembly 6 completes the closing action. In this way, there is no need to reset the energy storage component 2 by setting a reset structure, which saves production costs and saves assembly space in the circuit breaker 100.

[0104] In some embodiments, Figure 4 and Fig.11 As shown, the housing 5 includes a base 51. A stopper 52 is provided on the base 51. The stopper 52 abuts against the first torsion spring 4 to prevent the first torsion spring 4 from moving toward the base 51. A guide slope 22 is provided on the energy storage member 2. The first torsion spring 4 abuts against the energy storage member 2 along the guide slope 22.

[0105] An installation space is provided in the base 51 , and some internal components of the circuit breaker 100 are arranged in the installation space.

[0106] The limiting block 52 may be integrally formed with the base 51 , or the limiting block 52 and the base 51 may be separately formed and then assembled.

[0107] The guiding slope 22 can be integrally formed with the energy storage component 2 when the energy storage component 2 is formed, or the guiding slope 22 can be cut after the energy storage component 2 is formed.

[0108] During the assembly process of the circuit breaker 100, the first torsion spring 4 is generally installed first, and then the energy storage component 2 is installed. One end of the energy storage component 2 is connected to the handle 1, and the other end of the energy storage component 2 is provided with a guide bevel 22, and the guide bevel 22 abuts against one end of the first torsion spring 4. Specifically, the limit block 52 provided on the base 51 is used to fix the first torsion spring 4 on the base 51 and prevent one end of the first torsion spring 4 from moving toward the base 51. The energy storage component 2 is pressed toward the base 51, and under the limiting action of the limit block 52, one end of the first torsion spring 4 moves along the guide bevel 22. After one end of the first torsion spring 4 moves to the edge of the guide bevel 22, one end of the first torsion spring 4 abuts against the other side of the energy storage component 2, so that the first torsion spring 4 is partially deformed, so that the first torsion spring 4 fixes the energy storage component 2 on the base 51.

[0109] As can be seen from the above content, the limit block 52 has at least two limit surfaces. Specifically, the limit block 52 can be L-shaped or T-shaped.

[0110] In summary, the energy storage member 2 is provided with a guide slope 22. The first torsion spring 4 abuts against the energy storage member 2 along the guide slope 22. The energy storage member 2 is fixed on the base 51, and the connection between the energy storage member 2 and the first torsion spring 4 is realized, so that the energy storage member 2 is reset by the first torsion spring 4.
