Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a circuit breaker and a power system. Background Art

[0002] Circuit breakers are typically installed using a guide rail mounting method. The circuit breaker can be mounted using clips in the circuit breaker and guide rails or other mounting components to secure the circuit breaker in place.

[0003] To ensure proper operation of the circuit breaker, protect the circuit, and ensure personal safety, clips are typically made of insulating materials such as nylon. However, these clips are not strong enough and can easily break when the circuit breaker needs to be removed for maintenance, making it difficult to remove the circuit breaker from the mounting bracket. Utility Model Content

[0004] The present application provides a circuit breaker and a power system, which can reduce the possibility of snap breakage when removing the circuit breaker, thereby facilitating the removal of the circuit breaker.

[0005] In a first aspect, the present application provides a circuit breaker. The circuit breaker includes a circuit breaker body and a clip. The circuit breaker body is provided with a clip hole. The clip includes a main body and a frame. The main body is an insulating member, and the frame is a metal member. The frame is embedded in the main body, and the main body is clipped into the clip hole.

[0006] In the embodiment of the present application, the provision of the frame can increase the strength of the main body, making the buckle stronger. Thus, when removing the circuit breaker from the guide rail, the possibility of the buckle breaking due to external force, which would make the circuit breaker difficult to remove, can be reduced.

[0007] Optionally, the material of the skeleton is any one of stainless steel, aluminum alloy or copper alloy.

[0008] In this way, the mechanical strength of the frame can be made greater. Placing the frame made of the above materials inside the main body can effectively improve the strength of the buckle, making the buckle more durable.

[0009] Optionally, the material of the main body is plastic.

[0010] In this way, the main body can be made of plastic to wrap the metal skeleton to ensure the overall insulation of the buckle.

[0011] Optionally, the main body includes a frame and a clip. The clip is disposed within the frame, with one end of the clip connected to the frame and a gap between the other end of the clip and the frame, and the skeleton is embedded in the frame. The clip and a portion of the frame are located within a clip hole, and the clip is clipped into the clip hole.

[0012] With the above arrangement, when the buckle is clamped on the circuit breaker body, the frame can be operated to extend into the clamping hole, so that the clamping piece inside the frame can be clamped with the clamping hole, making the clamping more convenient.

[0013] Optionally, the skeleton is arranged on a side of the frame close to the gap.

[0014] In this way, the skeleton can strengthen the side of the frame near the gap. Therefore, during the process of dismantling the circuit breaker, the tool can apply force to the part of the frame where the skeleton is provided, which can effectively reduce the possibility of the frame breaking on the side near the gap.

[0015] Optionally, the skeleton extends along the circumferential direction of the frame.

[0016] In this way, the skeleton can enhance the strength of the periphery of the frame, and can also effectively reduce the possibility of the frame breaking on the side close to the gap during the process of dismantling the circuit breaker.

[0017] Optionally, the clamping hole has a first hole wall and a second hole wall relative to each other, the clamping member extends along the axial direction of the clamping hole, and a recessed portion is provided on the clamping member, which is recessed along the direction from the first hole wall to the second hole wall.

[0018] Through the above arrangement, the clamping piece can be curved, which can make the clamping piece have a certain elasticity.

[0019] Optionally, the circuit breaker body includes a housing, the engaging hole is provided on the housing, a engaging groove is provided on the hole wall of the engaging hole, the other end of the engaging member is embedded in the engaging groove, and the engaging member is elastic.

[0020] In this way, the buckle can be engaged with the housing of the circuit breaker body, which can reduce the possibility that the setting of the engaging hole will affect the part of the circuit breaker body that controls the on and off of the circuit.

[0021] Optionally, a plurality of snap-fit ​​holes are provided on the circuit breaker body, and a snap is provided in each snap-fit ​​hole.

[0022] In this way, when the circuit breaker body is mounted on the guide rail, it can be mounted through multiple clips, thereby improving the reliability of the installation of the circuit breaker body on the guide rail.

[0023] In a second aspect, an embodiment of the present application provides a power system, comprising a guide rail and a circuit breaker according to any one of claims 1 to 9, wherein the circuit breaker body is mounted on the guide rail by a snap-fit.

[0024] The beneficial effects of the power system provided in the above-mentioned second aspect and each possible design of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and each possible implementation method of the first aspect, and will not be repeated here.

[0039] In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, "connected" or "connected" in a mechanical structure can refer to a physical connection. For example, a physical connection can be a fixed connection, such as a fixed connection via a barrier, such as a screw, bolt, or other barrier. A physical connection can also be a removable connection, such as a snap-fit ​​connection.

A signal connection can refer not only to signal connection through an electrical circuit, but also to signal connection through a media medium, such as radio waves. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0040] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0041] For example, Figure 1 As shown, an embodiment of the present application provides a power system 200 , which includes a guide rail 201 and a circuit breaker 100 . The circuit breaker body 10 is mounted on the guide rail 201 via a buckle 20 .

[0042] The circuit breaker body 10 can be connected to the main circuit to cut off or connect the circuit and ensure the normal operation of the circuit.

[0043] The buckle 20 can then mount the circuit breaker body 10 on the guide rail 201. When the circuit breaker 100 needs to be installed later, it can be installed through the guide rail 201, making the installation of the circuit breaker 100 relatively simple.

[0044] The circuit breaker 100 provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0045] Reference Figure 1 and Figure 2As shown, an embodiment of the present application provides a circuit breaker 100, which includes a circuit breaker body 10 and a clip 20. The circuit breaker body 10 is provided with a clip hole 11. The clip 20 includes a main body 21 and a frame 22. The main body 21 is an insulating member, and the frame 22 is a metal member. The frame 22 is embedded in the main body 21, and the main body 21 is clipped into the clip hole 11.

[0046] The buckle 20 can be disposed in the engaging hole 11 of the circuit breaker body 10 and engaged with the engaging hole 11 . Thus, the buckle 20 can be disposed on the circuit breaker body 10 so that the circuit breaker body 10 can be mounted on the guide rail 201 through the buckle 20 .

[0047] The buckle 20 includes a main body 21 and a frame 22 . The frame 22 is embedded in the main body 21 . It can also be considered that the main body 21 wraps the frame 22 .

[0048] Since the frame 22 is a metal part, the strength of the frame 22 is relatively high. In this way, the provision of the frame 22 can increase the strength of the main body 21 and reduce the problem that the main body 21 is easily damaged.

[0049] The main body 21 is an insulating member, which can keep the buckle 20 insulated and meet the design standards of the buckle 20 in the circuit breaker 100, so that the circuit breaker body 10 can work normally and ensure personal safety.

[0050] That is, in the embodiment of the present application, the provision of the frame 22 can increase the strength of the main body 21, thereby increasing the strength of the clip 20. This can reduce the possibility of the clip 20 breaking due to external forces when removing the circuit breaker 100 from the guide rail 201, thereby reducing the possibility of the circuit breaker 100 being difficult to remove due to the problem.

[0051] In some embodiments, the material of the skeleton 22 can be any one of stainless steel, aluminum alloy or copper alloy.

[0052] Through the above configuration, the frame 22 can be made of stainless steel, aluminum alloy or copper alloy.

[0053] Among them, stainless steel, aluminum alloy and copper alloy all have relatively high mechanical strength. Placing the skeleton 22 made of the above materials inside the main body 21 can effectively improve the strength of the buckle 20, making the buckle 20 more durable.

[0054] Furthermore, when removing the circuit breaker 100, both the frame 22 and the main body 21 can withstand external forces. Thus, the frame 22 can share some of the applied force, reducing the possibility of the main body 21 breaking. This reduces the possibility of the clip 20 breaking during removal, making it difficult to remove the circuit breaker 100.

[0055] It should be noted that, in addition to the above-mentioned stainless steel, aluminum alloy and copper alloy, there are many other metals with high strength that can also be used to make the skeleton 22 to enhance the strength of the main body 21 .

[0056] For example, steel, titanium metal or chromium-nickel-inconel alloy, etc. The specific material of the skeleton 22 is not specifically limited in the embodiment of the present application.

[0057] In some embodiments, the material of the main body 21 may be plastic.

[0058] Through the above arrangement, the main body 21 can be made of plastic to wrap the metal skeleton 22 to ensure the overall insulation of the buckle 20.

[0059] The material of the main body 21 may specifically be nylon (Polyamide, PA), polyethylene (Polyethylene, PE), polycarbonate (Polycarbonate, PC), etc.

[0060] Thus, during the production of the buckle 20, injection molding can be used. The skeleton 22 can be placed in a mold, and then injection molding can be performed. After molding, the buckle 20 with the skeleton 22 embedded therein can be obtained, and production is also relatively simple.

[0061] It should be noted that the strength of the plastic body 21 will further decrease after long-term use and age. In the circuit breaker 100 proposed in this application, since the frame 22 is embedded in the body 21, the frame 22 is relatively strong. Even if the body 21 ages and breaks, the circuit breaker 100 can be disassembled through the frame 22.

[0062] In some embodiments, as Figure 2 and Figure 3 As shown, the main body 21 may include a frame 211 and a clamping member 212. The clamping member 212 is disposed within the frame 211, with one end of the clamping member 212 connected to the frame 211 and a gap 213 between the other end of the clamping member 212 and the frame 211. The skeleton 22 is embedded in the frame 211. The clamping member 212 and a portion of the frame 211 are located within the clamping hole 11, and the clamping member 212 is clamped to the clamping hole 11.

[0063] The main body 21 specifically includes a frame 211 and a clamping member 212, which is connected to the frame 211. When the buckle 20 is set on the circuit breaker body 10, the frame 211 can be operated to extend into the clamping hole 11, so that the clamping member 212 inside the frame 211 can be clamped with the clamping hole 11.

[0064] Since only a portion of the frame 211 is located in the engaging hole 11 , the frame 211 partially extends from the engaging hole 11 to engage with the guide rail 201 or facilitate applying force to remove the circuit breaker 100 from the guide rail 201 .

[0065] For ease of description, the two ends of the frame 211 in the axial direction of the engaging hole 11 are referred to as the first end of the frame 211 and the second end of the frame 211. The first end of the frame 211 is close to the gap 213, and the second end of the frame 211 is far away from the gap 213.

[0066] In the embodiment of the present application, a slot is provided on the circuit breaker body 10 , and the engaging hole 11 can be communicated with the slot.

[0067] After the clip 20 is set on the circuit breaker body 10, the second end of the frame 211 can be located in the slot. When the circuit breaker 100 is installed on the guide rail 201, the guide rail 201 can be located in the slot and engaged with the second end of the frame 211.

[0068] Furthermore, the first end of the frame 211 can extend from the engaging hole 11, so that at least a portion of the gap 213 is exposed outside the circuit breaker body 10. This allows for easy access for tools. To remove the circuit breaker 100, a tool can be inserted into the frame 211 through the gap 213 and apply force to the frame 211, causing the entire latch 20 to move away from the slot.

[0069] Furthermore, the portion of the buckle 20 located in the slot can be reduced, so that the buckle 20 is separated from the guide rail 201 , and the guide rail 201 can be separated from the slot.

[0070] In some embodiments, the skeleton 22 may be disposed on a side of the frame 211 close to the gap 213 .

[0071] According to the above description of the installation and removal of the circuit breaker 100 on the guide rail 201, when removing the circuit breaker 100, the tool will extend into the frame 211 through the gap 213 and apply a force to the frame 211 away from the gap 213, so that the frame 211 drives the latch 20 as a whole to move away from the slot.

[0072] During this process, the force on the frame 211 is mainly concentrated on the first end of the frame 211, near the gap 213. Therefore, when the circuit breaker 100 is removed, the side of the frame 211 near the gap 213 is easily broken, which can easily lead to the problem of difficult disassembly of the circuit breaker 100.

[0073] In the present application, the skeleton 22 can reinforce the strength of the side of the frame 211 near the gap 213. Therefore, during the disassembly of the circuit breaker 100, a tool can apply force to the portion of the frame 211 where the skeleton 22 is provided, which can effectively reduce the possibility of the frame 211 breaking on the side near the gap 213.

[0074] Moreover, in the embodiment of the present application, the skeleton 22 is only provided on one side close to the gap 213 , which can also reduce the use of the skeleton 22 , reduce the manufacturing cost of the buckle 20 , and also better reduce the possibility of the buckle 20 breaking.

[0075] It should be noted that the skeleton 22 is arranged on a side of the frame 211 close to the gap 213 , and may be arranged in different ways.

[0076] Reference Figure 2 The frame 211 is a rectangular structure. The frame 211 has a first side wall 216 and a second side wall 217, and a third side wall 218 and a fourth side wall 219. The first side wall 216, the third side wall 218, the second side wall 217, and the fourth side wall 219 are connected in sequence to form the frame 211.

[0077] The clamping member 212 is connected to the second side wall 217 and forms a gap 213 with the first side wall 216 .

[0078] In the present application, the frame 22 can be disposed inside the first side wall 216. Alternatively, the frame 22 can be disposed inside the first side wall 216 and inside the side of the third side wall 218 close to the first side wall 216. Alternatively, the frame 22 can also be disposed inside the first side wall 216 and inside the side of the fourth side wall 219 close to the first side wall 216, and so on.

[0079] The specific configuration of the skeleton 22 is not specifically limited in this embodiment of the present application.

[0080] In some embodiments, as Figure 3 As shown, the skeleton 22 can extend along the circumferential direction of the frame body 211 .

[0081] In this way, the skeleton 22 can strengthen the periphery of the frame 211. Therefore, the first end of the frame 211 is stronger, thereby effectively reducing the possibility of the frame 211 breaking on the side near the gap 213 during the disassembly of the circuit breaker 100.

[0082] In the embodiment of the present application, the skeleton 22 extends along the circumferential direction of the frame 211, that is, the skeleton 22 can be embedded in the first side wall 216, the second side wall 217, the third side wall 218, and the fourth side wall 219. In this way, the overall strength of the frame 211 can be enhanced, and the possibility of fracture at the location where the frame 211 is connected to the guide rail 201 or other locations can be reduced.

[0083] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 As shown, the snap-fit ​​hole 11 has a first hole wall 111 and a second hole wall 112 relative to each other, and the snap-fit ​​member 212 extends along the axial direction of the snap-fit ​​hole 11. The snap-fit ​​member 212 may be provided with a recessed portion 214, which is recessed along the direction from the first hole wall 111 to the second hole wall 112.

[0084] Through the above configuration, the clamping member 212 can be curved, which enables the clamping member 212 to have a certain degree of elasticity.

[0085] For ease of description, Figure 1 As shown, the direction from the slot to the engaging hole 11 is called the first direction X, and the direction from the engaging hole 11 to the slot is called the second direction Y.

[0086] Thus, when the circuit breaker body 10 is mounted on the guide rail 201 using the clip 20, the clip 212 engages with the clip hole 11, and the guide rail 201 applies a force along the first direction X to the frame 211, causing the frame 211 to squeeze the clip 212. Consequently, the clip 212 tends to recover its deformation and can apply a force along the second direction Y to the frame 211, ensuring a secure clip connection between the frame 211 and the guide rail 201.

[0087] When removing the circuit breaker 100 , a tool can be inserted into the gap 213 and apply a force to the frame 211 along the first direction X. In this way, the frame 211 can squeeze the clamping member 212 , causing the clamping member 212 to deform, thereby separating the circuit breaker 100 from the guide rail 201 .

[0088] After the circuit breaker 100 is removed, the tool can be operated to withdraw from the gap 213. At this time, the clamping member 212 can also extend under its own elastic force and apply a force along the second direction Y to the frame 211 to restore the frame 211 to a position where it is not connected to the guide rail 201.

[0089] It should be noted that the recessed portions 214 may be arranged at intervals or continuously.

[0090] In the case where the recessed portions 214 are arranged at intervals, a protruding portion 215 may be provided between two adjacent recessed portions 214, and the protruding portion 215 may protrude from the second hole wall 112 to the first hole wall 111, as shown in FIG. Figure 2 and Figure 3 In this way, the clamping member 212 can be made into a wave-like structure, and the elasticity of the clamping member 212 can be made better.

[0091] It is understood that the provision of the recessed portion 214 can facilitate the deformation of the clamping member 212, but the specific recessed direction of the recessed portion 214 has no effect on the deformation ability of the clamping member 212. Therefore, the recessed portion 214 is not limited to being recessed along the direction from the first hole wall 111 to the second hole wall 112, and can also be recessed along other directions.

[0092] It should also be noted that both the clip 212 and the frame 211 can be made of plastic, which can simplify the production of the buckle 20. On the other hand, the clip 212 made of plastic has a certain elasticity, which, combined with the special shape of the clip 212, can facilitate the deformation of the clip 212.

[0093] In some embodiments, the circuit breaker body 10 may include a housing, and the housing is provided with a clamping hole 11. A clamping groove 113 is provided on the hole wall of the clamping hole 11, and the other end of the clamping member 212 is embedded in the clamping groove 113, and the clamping member 212 is elastic.

[0094] The clamping hole 11 is provided on the housing, which can reduce the possibility that the setting of the clamping hole 11 affects the part of the circuit breaker body 10 that realizes the control circuit on and off.

[0095] The wall of the engaging hole 11 is provided with an engaging groove 113. When engaging the clip 20 in the engaging hole 11, the clip 20 can be placed in the groove with the first end of the frame 211 facing the engaging member 212. Then, the clip 20 can be pushed into the engaging hole 11, so that the engaging member 212 is embedded in the engaging groove 113. This achieves the engaging connection between the clip 20 and the circuit breaker body 10.

[0096] In the embodiment of the present application, the clamping groove 113 can limit the other end of the clamping member 212 so that the position of the other end of the clamping member 212 is fixed.

[0097] When installing the circuit breaker 100 on the guide rail 201 or removing the circuit breaker 100 from the guide rail 201 , force may be applied to the frame 211 so that the frame 211 drives one end of the clamping member 212 to move, thereby deforming the clamping member 212 .

[0098] In some embodiments, as Figure 1 and Figure 4 As shown, a plurality of snap-fit ​​holes 11 may be provided on the circuit breaker body 10 , and a snap 20 is provided in each snap-fit ​​hole 11 .

[0099] In this way, when the circuit breaker body 10 is installed on the guide rail 201 , it can be installed through the multiple clips 20 , thereby improving the reliability of the installation of the circuit breaker body 10 on the guide rail 201 .

[0100] It should be noted that the number of the clamping holes 11 can be 2, 3, 4, etc. The specific number of the clamping holes 11 is not specifically limited in the embodiment of the present application.

[0101] In the embodiment of the present application, the provision of the frame 22 can increase the strength of the main body 21, thereby increasing the strength of the clip 20. This can reduce the possibility of the clip 20 breaking due to external forces when removing the circuit breaker 100 from the guide rail 201, thereby reducing the possibility of the circuit breaker 100 being difficult to remove due to the problem of breaking.

[0102] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
