Description

Technical Field

[0001] This application relates to the technical field of low-voltage electrical appliances, and particularly to an elastic module of a clapper-type tripping mechanism and a circuit breaker. Background Art

[0002] Switching devices can protect the safety of circuits and prevent overload and short circuits. Taking a circuit breaker as an example, the circuit breaker has a certain current-breaking capacity and an automatic protection mechanism. A clapper-type tripping mechanism can be arranged inside the circuit breaker as required. The working principle of the clapper-type tripping mechanism is similar to the clapping action in machinery, that is, it can quickly and accurately trigger the opening operation of the circuit breaker under specific conditions.

[0003] The clapper-type tripping mechanism has a fast response speed. When a sudden fault occurs in the power system, such as a short circuit or overload, a response time in milliseconds is crucial for preventing equipment damage and ensuring personal safety. The clapper-type tripping mechanism has high reliability. Moreover, the clapper-type tripping mechanism also has a self-resetting function. After the fault is eliminated and the power supply is restored, the mechanism can automatically reset, enabling the circuit breaker to enter the standby state again without manual intervention.

[0004] However, the assembly process of the clapper-type circuit breaker is relatively complex, and it is difficult to adjust the elastic components. Summary of the Utility Model

[0005] This application provides an elastic module of a clapper-type tripping mechanism and a circuit breaker, which can realize the modular assembly of the tripping mechanism, improve the assembly efficiency, reduce the production cost, and can adapt to different circuit breaking requirements by replacing the elastic components.

[0006] In a first aspect, this application provides an elastic module of a clapper-type tripping mechanism, which is installed on the yoke or bracket of the tripping mechanism and is used to reset the armature of the tripping mechanism. The elastic module of the clapper-type tripping mechanism includes a mounting seat and an elastic component.

[0007] The mounting seat is detachably connected to the yoke or bracket. The elastic component is installed on the mounting seat. The first end of the elastic component abuts against the mounting seat, and the second end of the elastic component is directly or indirectly connected to the armature. The elastic component can reset the armature through a pulling force or a supporting force.

[0008] Among them, by replacing elastic components of different models, the reset performance of the elastic component on the armature can be changed.

[0009] The elastic module of this application is a detachable modular setting, which can realize the modular assembly of the tripping mechanism, improve the assembly efficiency, and reduce the production cost. The above elastic module can be installed on the yoke or bracket of the tripping mechanism. Through the elastic module, the armature can be reset and the stable operation of the tripping mechanism can be ensured.

[0010] Specifically, the elastic module includes a mounting seat and an elastic member. The mounting seat is detachably connected to the yoke or bracket. This arrangement is not only convenient for maintenance and replacement, but also invisibly improves the flexibility and reliability of the entire tripping mechanism. The elastic member is mounted on the mounting seat, and the two ends of the elastic member are respectively connected or abutted to different positions. The first end of the elastic member abuts the mounting seat, and the other end of the elastic member is directly or indirectly connected to the armature. Through the elastic force characteristics of the elastic member, the armature can be accurately reset.

[0011] It is worth noting that the selection and configuration of the elastic member can be set as needed. Different types of elastic members have different elastic characteristics. These differences enable them to provide just the right elastic preload for switch devices such as circuit breakers with different requirements.

[0012] In some examples, at least one mounting slot is provided on the yoke or the bracket, and the mounting seat is detachably connected to the mounting slot.

[0013] The mounting groove can be provided on the yoke as required, or the mounting groove can be provided on the bracket. By providing the mounting groove, an efficient and detachable connection between the mounting seat and the elastic module is achieved. The mounting groove is provided according to the specific time requirements, as long as the mounting seat can be assembled, thereby achieving modular installation of the entire elastic module. The mounting groove can also be provided on both the bracket and the yoke as required to improve the installation stability of the spring module.

[0014] In some examples, at least two mounting slots are provided, and the distances between different mounting slots and the armature are different. After the mounting seat is installed in different mounting slots, the resetting performance of the elastic module on the armature is different.

[0015] When setting a tripping mechanism including an armature and an elastic module, by providing a plurality of mounting slots and making the spacing between each mounting slot and the armature different, the performance of the elastic module during the resetting process can be regulated.

[0016] As a component of an electromagnetic device such as a tripping mechanism, the armature position change is often directly affected by the electromagnetic force. The elastic module is used to reset the armature and is directly related to the stability and response speed of the entire tripping system.

[0017] Different from the traditional single mounting groove setting, after adopting the multi-groove setting, the distances between different mounting grooves and the armature can be different. Specifically, mounting grooves with different distances can cooperate with the elastic module to have different effects on the movement trajectory of the armature. When the armature is in a certain specific position, the corresponding mounting groove will provide a specific support point, thereby affecting the force received by the elastic module during the reset process. By adjusting the elastic module to different mounting grooves, key parameters such as the pre-tightening force and spring constant received by the elastic module can be changed, and thus the fine control of the reset performance can be achieved.

[0018] In some examples, a first elastic buckle is provided on the mounting base, and a clamping groove adapted to the first elastic buckle is provided in the mounting groove.

[0019] The above-mentioned first elastic buckle is a structure with certain elasticity, which can automatically adapt to the shape and size of the mounting groove during the installation process to achieve the effect of relative clamping. When the mounting base is placed into the mounting groove, the first elastic buckle will partially abut against the inner wall of the mounting groove due to its own elasticity until it matches and clamps with the clamping groove. This setting not only simplifies the installation process but also greatly improves the stability and firmness of the connection. The setting of the clamping groove not only provides stable support for the first elastic buckle but also makes the connection tighter and more reliable.

[0020] In some examples, the first elastic buckle includes a first elastic arm and a first claw, and an avoidance groove adapted to the first elastic arm is provided on the mounting base, and there is enough avoidance space for the first elastic arm to move in the avoidance groove.

[0021] The first elastic buckle can slide into the mounting groove and make the first claw snap into the clamping groove.

[0022] The first elastic buckle consists of two key parts: the first elastic arm and the first claw. The first elastic arm and the first claw jointly complete the main function of the buckle. The first elastic arm can be used as the power source of the entire first elastic buckle, and its material needs to have good elasticity and toughness to ensure that it can respond quickly and accurately when subjected to external forces. The shape and size of the first claw can accurately snap into the preset clamping groove to achieve a stable connection.

[0023] In some examples, a first guiding inclined surface and a second guiding inclined surface are respectively provided on two opposite sides of the first claw. When the first elastic buckle snaps into the mounting groove, the first guiding inclined surface can abut against the notch of the mounting groove and drive the first elastic buckle to slide into the mounting groove. When the mounting base continues to slide relative to the mounting groove, the first claw can snap into the clamping groove.

[0024] When the first elastic buckle disengages from the clamping groove, the second guiding inclined surface can abut against the inner wall of the clamping groove and drive the first claw to disengage from the clamping groove. When the mounting base continues to slide relative to the mounting groove, the entire mounting base disengages from the mounting groove.

[0025] The first claw is the clamping part of the first elastic buckle. The first guiding inclined surface and the second guiding inclined surface are respectively arranged on both sides of the first claw. The setting of these two inclined surfaces is based on mechanical principles and actual application requirements. When the first elastic buckle first contacts and snaps into the installation groove, the first guiding inclined surface can gently abut against the edge of the notch of the installation groove, and guide the first elastic buckle to slowly slide into the deep part of the installation groove in an almost seamless manner. This process is not only smooth and unobstructed, but also greatly reduces the damage or jamming phenomenon that may be caused by direct impact, ensuring the smooth progress of the installation.

[0026] When the mounting seat needs to be disassembled, the same guiding inclined surface mechanism comes into play again. At this time, the second guiding inclined surface abuts against the inner wall of the clamping groove to drive the first claw to gradually disengage from the clamping groove. This process is also smooth and efficient, avoiding damage or component wear caused by violent disassembly.

[0027] In some examples, the mounting seat includes a main body part and a mounting part. The main body part is used to mount the elastic part, the mounting part is detachably connected to the installation groove, and the first elastic buckle is arranged on the mounting part.

[0028] The above-mentioned main body part is the main part of the entire mounting seat, and the main body part can be used to mount the elastic part. The elastic part is an element that transmits force, buffers vibration or realizes specific functions. The stability and accuracy of the installation of the elastic part directly affect the performance of the entire elastic module. Therefore, the setting of the main body part often undergoes calculation and simulation tests to ensure its effective support and protection for the elastic part, and at the same time meet the usage requirements under various complex working conditions.

[0029] As the connecting part between the mounting seat and the installation groove, the mounting part is set with full consideration of detachability and convenience. This setting not only facilitates the quick disassembly and assembly during installation and maintenance, but also effectively reduces the downtime caused by replacement or repair, thereby improving the overall production efficiency.

[0030] In some examples, an assembly groove is formed on the main body part, the elastic part is installed in the assembly groove, and the elastic part extends out of the assembly groove.

[0031] The part of the elastic part extending out of the assembly groove can directly or indirectly abut against the bottom of the armature to provide a certain elastic support for the armature. The assembly groove can make the connection of the elastic part more stable and reliable. The above-mentioned main body part can be an insulating part. Such a setting can reduce the possibility of the elastic part directly contacting the conductive part, especially when the extending part of the elastic part indirectly abuts against the armature, which can reduce the heat received by the elastic part and extend the service life of the elastic part.

[0032] In some examples, the elastic module further includes a cover body, which covers the notch of the assembly groove. The first end of the elastic member abuts against the bottom wall of the assembly groove, and the second end of the elastic member abuts against the cover body and indirectly abuts against the armature through the cover body.

[0033] The side surface of the cover body is provided with a second elastic buckle, and the inner wall of the assembly groove is provided with a limiting groove adapted to the second elastic buckle, and the second elastic buckle can be snapped into the limiting groove.

[0034] The limiting groove has a sliding space, and the snapping part of the second elastic buckle can slide within the sliding space.

[0035] The cover body is an integral part of the elastic module. The cover body covers the notch of the assembly groove, which can provide a certain protection for the elastic member in the assembly groove. This setting not only effectively prevents the intrusion of external impurities, but also ensures the stability and safety of the elastic member. At the same time, the cover body also provides a basis for the installation and fixation of the elastic member.

[0036] Both ends of the elastic member are respectively connected to the mounting seat and the cover body. Specifically, the first end of the elastic member tightly abuts against the bottom wall of the assembly groove, providing support for the entire module. The second end of the elastic member is connected to the cover body and indirectly abuts against the armature through the cover body. This setting not only realizes the effective transmission of force, but also ensures that the module can respond quickly and accurately when subjected to external forces.

[0037] The side surface of the cover body is provided with a second elastic buckle. This setting provides more convenience and flexibility for the assembly and fixation of the elastic module. When the cover body is installed into the assembly groove, the second elastic buckle can be accurately snapped into the limiting groove on the inner wall of the assembly groove. This snapping method is not only firm and reliable, but also can absorb and relieve the impact and vibration generated by external forces to a certain extent.

[0038] In a second aspect, the present application provides a circuit breaker, including the elastic module of the above-mentioned clapper-type tripping mechanism and a housing, and the elastic module is arranged in the housing.

[0039] The circuit breaker with the above-mentioned elastic module can realize the modular assembly of the tripping mechanism, improve the assembly efficiency, reduce the production cost, and can adapt to different tripping requirements by replacing the elastic member. And through the cooperation of the elastic module and multiple installation grooves, it can be realized that after the elastic module is installed in different installation grooves, the key parameters such as the pre-tightening force and spring constant received by the elastic module can be changed, so as to realize the fine regulation of the reset performance.

Detailed implementation manners

[0051] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application.

[0052] To solve the above technical problems, please refer to Figures 1-8 As shown, a first aspect of the present application provides an elastic module 100 of a clapper-type tripping mechanism, which can realize modular assembly of the tripping mechanism, improve the assembly efficiency, reduce the production cost, and can adapt to different tripping requirements by replacing the elastic member 120.

[0053] Refer to Figures 1 to 3 , in some examples, the elastic module 100 of the clapper-type tripping mechanism is installed on the yoke 300 or the bracket 400 of the tripping mechanism for resetting the armature 200 of the tripping mechanism. The elastic module 100 of the clapper-type tripping mechanism includes a mounting seat 110 and an elastic member 120.

[0054] The mounting seat 110 is detachably connected to the yoke 300 or the bracket 400. The elastic member 120 is installed on the mounting seat 110. The first end of the elastic member 120 abuts against the mounting seat 110, and the second end of the elastic member 120 is directly or indirectly connected to the armature 200. The elastic member 120 can reset the armature 200 through a pulling force or a supporting force.

[0055] Among them, by replacing elastic members 120 of different models, the reset performance of the elastic member 120 on the armature 200 can be changed. Elastic members 120 of different models have different elastic forces, and corresponding elastic pre-tightening forces can be provided for different tripping requirements, which are specifically set according to actual needs.

[0056] The elastic module 100 of the present application is a detachable modular setting, which can realize modular assembly of the tripping mechanism, improve the assembly efficiency and reduce the production cost.

[0057] The above-mentioned elastic module 100 can be installed on the yoke 300 or the bracket 400 of the tripping mechanism. Through the elastic module 100, the armature 200 can be reset to ensure the stable operation of the tripping mechanism.

[0058] Specifically, the elastic module 100 includes a mounting seat 110 and an elastic member 120. The mounting seat 110 is detachably connected to the yoke 300 or the bracket 400. This arrangement is not only convenient for maintenance and replacement, but also invisibly improves the flexibility and reliability of the entire tripping mechanism. The elastic member 120 is mounted on the mounting seat 110, and the two ends of the elastic member 120 are respectively connected or abutted to different positions. The first end of the elastic member 120 abuts the mounting seat 110, and the other end of the elastic member 120 is directly or indirectly connected to the armature 200. Through the elastic force characteristics of the elastic member 120, the armature 200 can be accurately reset. The connection of the elastic member 120 can be connected by welding, clamping, bundling, bonding, etc. It is also possible to simply abut the force application position of the elastic member 120 to the mounting seat 110 or the armature 200.

[0059] It is worth noting that the selection and configuration of the elastic member 120 can be set as needed. Different types of elastic members 120 have different elastic characteristics. These differences enable them to provide just the right elastic preload for switch devices such as circuit breakers with different requirements. This personalized configuration method not only ensures the stable operation of the trip mechanism under different working conditions, but also invisibly improves the adaptability and reliability of the entire circuit breaker.

[0060] The elastic module 100 of the present application adopts an innovative modular setting. This setting makes the elastic module 100 an independent, detachable unit. This modular assembly method not only greatly simplifies the assembly process, improves assembly efficiency, but also reduces production costs. At the same time, the elastic module 100 also allows users to flexibly replace and adjust the configuration of the elastic module 100 according to different needs and scenarios, thereby achieving precise control and optimization of the performance of the tripping mechanism.

[0061] In addition, as an indispensable part of the power system, the stability and reliability of the performance of the snap-on tripping mechanism is of vital importance to the safe operation of the entire system. As one of the key components in the tripping mechanism, the setting and configuration of the elastic module 100 directly affects the performance of the entire mechanism. Therefore, when setting and selecting the elastic module 100, the comprehensive influence of various factors must be fully considered to ensure that it can perform at its best in practical applications.

[0062] In summary, the elastic module 100 of the snap-on tripping mechanism plays a sufficient role in resetting the armature 200 and ensuring the stable operation of the tripping mechanism. At the same time, its detachable modular setting also provides more convenience and choice space.

[0063] In the snap-on release mechanism of the present application, the armature 200 is rotatably connected to the bracket 400 or the yoke 300 via the rotating shaft 500.Figures 1 to 3 One end of the middle armature 200 is rotatably connected to the bracket 400 through a rotating shaft 500. A latching structure is provided at the second end of the armature 200, which can latch the lock and drive the jump latch to unlock to achieve tripping. A limiting protrusion 410 adapted to the second end of the armature 200 is provided on the bracket 400. The limiting protrusion 410 can be a folding structure. Through the cooperation of the limiting protrusion 410 and the elastic module 100, the movement range of the armature 200 can be limited.

[0064] Refer to Figure 3 and Figure 4 As shown, in some examples, at least one mounting groove 310 is provided on the yoke 300 or the bracket 400, and the mounting seat 110 is detachably connected to the mounting groove 310.

[0065] The mounting groove 310 can be opened on the yoke 300 as needed, or the mounting groove 310 can be opened on the bracket 400. By providing the mounting groove 310, an efficient and detachable connection between the mounting seat 110 and the elastic module 100 is achieved. The mounting groove 310 is specifically set according to time needs, as long as the assembly of the mounting seat 110 can be realized, and then the modular installation of the entire elastic module 100 can be realized. The mounting groove 310 can also be opened on both the bracket 400 and the yoke 300 as needed to improve the installation stability of the spring module.

[0066] The setting of the mounting groove 310 can better realize the detachable connection of the mounting seat 110, and it is easier to realize the modular assembly method. It not only greatly simplifies the assembly process, improves the assembly efficiency, but also can reduce the production cost.

[0067] As the key to the modular setting, the setting position and quantity of the mounting groove 310 can be selected according to actual needs. At least one mounting groove 310 is opened on the yoke 300 or the bracket 400, providing a stable and flexible connection point for the mounting seat 110. This setting enables the mounting seat 110 to be easily embedded in the mounting groove 310, realizing the rapid docking between modules.

[0068] The opening position of the mounting groove 310 is not fixed, but can be flexibly adjusted according to actual needs. Whether the mounting groove 310 is set on the yoke 300, or the bracket 400 is selected as the carrier of the mounting groove 310, or both, the aim is to achieve the best assembly effect and stability.

[0069] Refer to Figure 3 and Figure 4 As shown, in some examples, at least two mounting grooves 310 are provided, and the distances between different mounting grooves 310 and the armature 200 are different. After the mounting seat 110 is installed in different mounting grooves 310, the reset performance of the elastic module 100 on the armature is different.

[0070] When setting up the tripping mechanism including the armature 200 and the elastic module 100, by setting a plurality of mounting grooves 310 and making the distances between each mounting groove 310 and the armature 200 different, the performance of the elastic module 100 during the reset process can be regulated.

[0071] The armature 200, as a component in an electromagnetic device such as a tripping mechanism, the change in the position of the armature 200 is often directly affected by the electromagnetic force. The elastic module 100 is used to reset the armature 200 and is directly related to the stability and response speed of the entire tripping system.

[0072] Different from the traditional single mounting groove 310 setting, after adopting the multi-groove setting, the distances between different mounting grooves 310 and the armature 200 can be different. Specifically, the mounting grooves 310 with different distances can cooperate with the elastic module 100 to have different effects on the movement trajectory of the armature 200. When the armature 200 is in a certain specific position, the corresponding mounting groove 310 will provide a specific support point, thereby affecting the force-bearing situation of the elastic module 100 during the reset process. By adjusting the elastic module 100 to be installed in different mounting grooves 310, key parameters such as the pre-tightening force and spring constant received by the elastic module 100 can be changed, and thus the fine regulation of the reset performance can be achieved.

[0073] Taking the three-groove setting scheme as an example. When the distances between the three corresponding mounting grooves 310 and the armature 200 are A, B, and C respectively (A < B < C), the reset times of the elastic module 100 are significantly different. Specifically, the reset time under the distance A is the shortest, while the reset time under the distance C is the longest. This discovery not only verifies the effectiveness of the multi-groove setting but also provides valuable reference for subsequent optimization work.

[0074] According to Hooke's Law, the elastic force of an elastic member 120 such as a spring is proportional to its deformation. Therefore, during the reset process of the elastic module 100, its elastic force will gradually increase as the deformation decreases. And the distance of the mounting groove 310 directly determines the range of deformation change of the elastic module 100 during the reset process. By adjusting the distance, the regulation of the elastic force change rate can be achieved, thereby optimizing the reset performance.

[0075] In summary, the multi-groove setting of the mounting groove 310 and the distance adjustment (the distance adjustment between the mounting seat 110 in the elastic module 100 and the armature bracket 400) in the setting of electromagnetic-related devices (such as the clapper-type tripping mechanism in this application) not only concerns the stability and response speed of the system but also directly affects the performance of the entire system.

[0076] For another example, there can be two installation grooves 310 arranged from bottom to top. The lower installation groove 310 is groove 1. At this time, the corresponding circuit breaker can be a type C circuit breaker, and the rated current can be 63A. At this time, the tripping mechanism needs to close and break the circuit after a large current appears and the value of the large current reaches eight times the rated current, that is, the tripping trigger current for breaking the circuit is 8 * 63A.

[0077] The upper installation groove 310 is groove 2. At this time, the corresponding circuit breaker can be a type D circuit breaker, and the rated current can also be 63A. At this time, the tripping mechanism needs to close and break the circuit after a large current appears and the value of the large current reaches twelve times the rated current, that is, the tripping trigger current for breaking the circuit is 12 * 63A.

[0078] When the assembly space is sufficient, groove 3 can also be set below groove 1 as needed. The installation grooves 310 are groove 3, groove 1, and groove 2 from bottom to top respectively. When the elastic module 100 is installed into groove 3, the corresponding circuit breaker can be a type B circuit breaker, and the rated current can also be 63A. At this time, the tripping mechanism needs to close and break the circuit after a large current appears and the value of the large current reaches three to five times the rated current. Taking three times as an example, that is, the tripping trigger current for breaking the circuit is 3 * 63A.

[0079] The above is an exemplary specification with 63A as an example. The rated current of the specific circuit breaker is set according to actual needs, and the installation position of the corresponding elastic module 100 and the elastic force of the elastic member 120 can be adjusted adaptively.

[0080] Refer to Figures 5 to 7 As shown, in some examples, a first elastic buckle 113 is provided on the mounting seat 110, and a card slot 320 adapted to the first elastic buckle 113 is provided in the installation groove 310. The setting of the first elastic buckle 113 can improve the connection stability between the mounting seat 110 and the installation groove 310. In the attached drawings of the present application, the installation groove 310 is opened in the yoke 300 as an example for exemplary illustration. By providing the card slot 320 in the installation groove 310, the connection stability between the mounting seat 110 and the yoke 300 can be further improved.

[0081] In traditional connection methods, fasteners such as bolts and nuts are often used to fix components, but these methods have disadvantages such as cumbersome installation and easy loosening. The setting of the elastic buckle provides a more convenient and reliable connection method.

[0082] The above-mentioned first elastic buckle 113 is a structure with certain elasticity, which can automatically adapt to the shape and size of the installation groove 310 during the installation process to achieve the effect of relative clamping. When the mounting base 110 is placed into the installation groove 310, the first elastic buckle 113 will partially abut against the inner wall of the installation groove 310 due to its own elasticity until it matches and clamps with the card slot 320. This setting not only simplifies the installation process but also greatly improves the stability and firmness of the connection. The setting of the card slot 320 not only provides stable support for the first elastic buckle 113 but also makes the connection tighter and more reliable.

[0083] The setting of the first elastic buckle 113 makes full use of the elastic deformation ability of the material, and realizes the tight fit with the card slot 320 through the elastic deformation of the buckle. This setting not only reduces the stress concentration phenomenon at the connection part but also improves the fatigue resistance of the connection part. In addition, due to the elastic deformation of the buckle having a certain buffering effect, it can also reduce the damage caused to the connection part by factors such as vibration to a certain extent.

[0084] Refer to Figures 5 to 7 As shown, in some examples, the first elastic buckle 113 includes a first elastic arm 1131 and a first claw 1132. An avoidance groove 1121 adapted to the first elastic arm 1131 is provided on the mounting base 110, and there is an avoidance space 1122 in the avoidance groove 1121 sufficient for the first elastic arm 1131 to move.

[0085] The first elastic buckle 113 can slide into the installation groove 310 and make the first claw 1132 snap into the card slot 320.

[0086] The first elastic buckle 113 consists of two key parts: the first elastic arm 1131 and the first claw 1132. The first elastic arm 1131 and the first claw 1132 together complete the main function of the buckle. The first elastic arm 1131 can serve as the power source of the entire first elastic buckle 113, and its material needs to have good elasticity and toughness to ensure that it can respond quickly and accurately when subjected to external forces. The shape and size of the first claw 1132 can accurately snap into the preset card slot 320 to achieve a stable connection.

[0087] The mounting base 110 not only plays a role in supporting and fixing, but also can be provided with an avoidance groove 1121 on the mounting base 110. Through the avoidance groove 1121, necessary space can be provided for the movement of the first elastic arm 1131. The size and position of the avoidance groove 1121 are calculated to ensure that the first elastic arm 1131 can freely expand and contract when subjected to external forces without being hindered.

[0088] When the first elastic buckle 113 starts to engage, under the push of an external force, the first elastic arm 1131 slowly slides into the installation groove 310 on the mounting base 110. During this process, the first elastic arm 1131 utilizes its elasticity and toughness to avoid possible obstacles and smoothly reaches the predetermined position. Subsequently, when the first claw 1132 reaches the position of the card slot 320, it precisely snaps into the preset card slot 320. Subsequently, the components of the mounting base 110 and the installation groove 310 are tightly connected together.

[0089] It should be noted that when selecting the material of the first elastic arm 1131, multiple factors such as its elastic modulus, yield strength, and fatigue resistance can be comprehensively considered according to needs; when setting the avoidance groove 1121, its shape, size, and position parameters need to be accurately calculated to ensure the smooth movement of the first elastic arm 1131.

[0090] The first elastic buckle 113 also has the characteristics of simple and quick installation, stable and reliable connection, and low maintenance cost. It not only improves the overall performance and reliability of the elastic module 100 but also makes disassembly and assembly more convenient and comfortable.

[0091] In some examples, the first guiding inclined surface 1133 and the second guiding inclined surface 1134 are respectively arranged on the two opposite sides of the first claw 1132. When the first elastic buckle 113 snaps into the installation groove 310, the first guiding inclined surface 1133 can abut against the notch of the installation groove 310 and drive the first elastic buckle 113 to slide into the installation groove 310. When the mounting base 110 continues to slide relative to the installation groove 310, the first claw 1132 can be snapped into the card slot 320.

[0092] When the first elastic buckle 113 disengages from the card slot 320, the second guiding inclined surface 1134 can abut against the inner wall of the card slot 320 and drive the first claw 1132 to disengage from the card slot 320. When the mounting base 110 continues to slide relative to the installation groove 310, the entire mounting base 110 disengages from the installation groove 310.

[0093] The first claw 1132 is the engaging part of the first elastic buckle 113. The first guiding inclined surface 1133 and the second guiding inclined surface 1134 are respectively arranged on the two sides of the first claw 1132. The setting of these two inclined surfaces is based on mechanical principles and actual application requirements. When the first elastic buckle 113 first contacts and snaps into the installation groove 310, the first guiding inclined surface 1133 can gently abut against the edge of the notch of the installation groove 310 and guide the first elastic buckle 113 to slowly slide into the deep part of the installation groove 310 in an almost seamless manner. This process is not only smooth and unobstructed but also greatly reduces the damage or jamming phenomenon that may be caused by direct impact, ensuring the smooth progress of the installation.

[0094] As the mounting base 110 slides further, the first claw 1132 begins to play its key role. The first claw 1132 can be snapped into the card slot 320, forming a firm connection. This connection can withstand a certain amount of external force impact, ensuring the stability and safety of the device during operation.

[0095] When it is necessary to disassemble the mounting base 110, the same guiding inclined plane mechanism comes into play again. At this time, the second guiding inclined plane 1134 abuts against the inner wall of the card slot 320 to drive the first claw 1132 to gradually disengage from the card slot 320. This process is also smooth and efficient, avoiding damage or component wear that may be caused by violent disassembly.

[0096] More notably, this setting demonstrates extremely high flexibility and adaptability in practical applications. Whether facing a complex and changeable installation environment or occasions that require frequent installation and disassembly, it can easily handle them, demonstrating excellent performance and reliability. In addition, this setting also fully considers the actual needs and operating habits of the staff. By optimizing the structural setting and operation process, it greatly reduces the difficulty and time cost of installation and disassembly, improving the overall work efficiency.

[0097] Refer to Figure 5 and Figure 7 As shown, in some examples, the mounting base 110 includes a main body portion 111 and a mounting portion 112. The main body portion 111 is used to mount the elastic member 120. The mounting portion 112 is detachably connected to the mounting groove 310. The first elastic buckle 113 is provided on the mounting portion 112.

[0098] The above-mentioned main body portion 111 is the main body portion 111 of the entire mounting base 110. The main body portion 111 can be used to mount the elastic member 120. The elastic member 120 is an element that transmits force, buffers vibration, or realizes specific functions. The stability and accuracy of the installation of the elastic member 120 directly affect the performance of the entire elastic module 100. Therefore, the setting of the main body portion 111 often undergoes calculations and simulation tests to ensure its effective support and protection for the elastic member 120, while meeting the usage requirements under various complex working conditions.

[0099] As the connecting part that connects the mounting base 110 and the mounting groove 310, the mounting portion 112 is set with full consideration of detachability and convenience. This setting not only facilitates the quick disassembly and assembly during installation and maintenance, but also effectively reduces the downtime caused by replacement or repair, thereby improving the overall production efficiency.

[0100] It should be noted that the installation part 112 incorporates the setting of the first elastic buckle 113. This innovative setting not only enhances the connection strength between the installation part 112 and the installation groove 310, but also endows the installation seat 110 with a certain self - adapting ability. When facing minor displacements or deformations, the first elastic buckle 113 can automatically adjust and compensate, thereby maintaining the tightness and reliability of the connection.

[0101] In some examples, an assembly groove 114 is formed on the main body part 111, and the elastic member 120 is installed in the assembly groove 114 and extends out of the assembly groove 114.

[0102] The part of the elastic member 120 extending out of the assembly groove 114 can directly or indirectly abut against the bottom of the armature 200 to provide a certain elastic support for the armature 200. The assembly groove 114 can make the connection of the elastic member 120 more stable and reliable. The above - mentioned main body part 111 can be an insulating part. Such a setting can reduce the possibility of the elastic member 120 directly contacting the conductive part, especially when the extending part of the elastic member 120 indirectly abuts against the armature 200. This can reduce the heat received by the elastic member 120 and extend the service life of the elastic member 120.

[0103] The elastic member 120 of the present application can be an elastic structure such as a spring, a coil spring, a torsion spring, a spring sheet, etc. Different elastic structures can adaptively adjust the connection method according to the position of the force arm and can be used in cooperation with a certain transmission mechanism when necessary.

[0104] In the present application, the elastic member 120 is exemplarily described by taking a spring as an example. The spring in the attached drawings is a square columnar spring adapted to the shape of the assembly groove 114. When the assembly groove 114 is a cylindrical groove or other shapes, the shape of the spring can also be adaptively changed accordingly.

[0105] Refer to Figure 7 and Figure 8 As shown, in some examples, the elastic module 100 further includes a cover body 130. The cover body 130 covers the notch of the assembly groove 114. The first end of the elastic member 120 abuts against the bottom wall of the assembly groove 114, and the second end of the elastic member 120 abuts against the cover body 130 and indirectly abuts against the armature 200 through the cover body 130.

[0106] The side surface of the cover body 130 is provided with a second elastic buckle 131, and the inner wall of the assembly groove 114 is provided with a limiting groove 115 adapted to the second elastic buckle 131. The second elastic buckle 131 can be snapped into the limiting groove 115.

[0107] The limiting groove 115 has a sliding space 1151, and the snapping part of the second elastic buckle 131 can slide in the sliding space 1151.

[0108] The cover body 130 is a component of the elastic module 100. The cover body 130 covers the notch of the assembly groove 114, which can provide a certain protection for the elastic member 120 in the assembly groove 114. This setting not only effectively prevents the intrusion of external impurities, but also ensures the stability and safety of the elastic member 120. At the same time, the cover body 130 also provides a basis for the installation and fixation of the elastic member 120.

[0109] Both ends of the elastic member 120 are respectively connected to the mounting seat 110 and the cover body 130. Specifically, the first end of the elastic member 120 is in close contact with the bottom wall of the assembly groove 114, providing support for the entire module. The second end of the elastic member 120 is connected to the cover body 130 and indirectly abuts against the armature 200 through the cover body 130. This setting not only realizes the effective transmission of force, but also ensures that the module can respond quickly and accurately when subjected to external forces.

[0110] A second elastic buckle 131 is provided on the side surface of the cover body 130. This setting provides more convenience and flexibility for the assembly and fixation of the elastic module 100. When the cover body 130 is installed in the assembly groove 114, the second elastic buckle 131 can be accurately snapped into the limiting groove 115 on the inner wall of the assembly groove 114. This snapping method is not only firm and reliable, but also can absorb and relieve the impact and vibration generated by external forces to a certain extent.

[0111] The limiting groove 115 provides guidance and positioning for the second elastic buckle 131. Moreover, a sliding space 1151 is provided in the limiting groove 115. The existence of this sliding space 1151 enables the snapping part of the second elastic buckle 131 to slide freely therein, thereby realizing the mobility of the cover body 130 relative to the mounting seat 110. When there is an external force, such as when the armature 200 presses the cover body 130, the elastic pre-tightening force of the elastic member 120 in the assembly groove 114 will be overcome during the movement of the cover body 130 relative to the mounting seat 110. This setting improves the assembly accuracy and stability of the elastic module 100.

[0112] Both the mounting seat 110 and the cover body 130 of the present application can be set as insulating structures. Such a setting can reduce the possibility of the elastic member 120 directly contacting the conductive member, and thus can reduce the heat received by the elastic member 120 and extend the service life of the elastic member 120.

[0113] The above-mentioned limiting groove 115 can be a blind hole structure provided on the inner wall of the assembly groove 114, or a through hole structure penetrating the wall surface of the assembly groove 114, which is specifically set according to needs.

[0114] The end of the cover body 130 facing away from the elastic member 120 may be provided with an abutment protrusion 132, which may directly abut against the armature 200. When the abutment protrusion 132 is pressed by the armature 200, it may rotate relative to the armature 200. The surface of the abutment protrusion 132 may be set as an arc surface, specifically a circular arc surface. Such a setting may make the relative rotation between the armature 200 and the abutment protrusion 132 smoother.

[0115] The second elastic buckle 131 includes a second elastic arm 1311 and a second claw 1312. The second elastic arm 1311 can extend into the assembly groove 114 on the mounting base 110. The second claw 1312 can be clamped into the limiting groove 115 on the inner wall of the assembly groove 114. The limiting groove 115 has a sliding space 1151 sufficient for the second claw 1312 to slide.

[0116] The second elastic buckle 131 can slide into the assembly slot 114 and enable the second claw 1312 to be engaged with the limiting slot 115 .

[0117] In some examples, a third guide bevel 1313 and a fourth guide bevel 1314 are respectively provided on the opposite sides of the second claw 1312. When the second elastic clip 131 is inserted into the assembly groove 114, the third guide bevel 1313 can abut against the notch of the assembly groove 114 and drive the second elastic clip 131 to slide into the assembly groove 114. The cover body 130 continues to slide relative to the assembly groove 114, and the second claw 1312 can be connected to the limit groove 115.

[0118] When the second elastic buckle 131 is disengaged from the limiting groove 115 , applying external force can enable the fourth guide slope 1314 to abut the inner wall of the limiting groove 115 and drive the second claw 1312 to disengage from the limiting groove 115 , and the cover body 130 continues to slide relative to the assembly groove 114 , and the cover body 130 as a whole is disengaged from the assembly groove 114 .

[0119] The mounting groove 310 , the mounting portion 112 , the first elastic buckle 113 and the second elastic buckle 131 in the present application can all be arranged in pairs, which can provide higher connection stability.

[0120] In a second aspect, the present application provides a circuit breaker, comprising an elastic module 100 of the above-mentioned snap-on tripping mechanism and a housing, wherein the elastic module 100 is disposed in the housing.

[0121] The circuit breaker with the above elastic module 100 enables modular assembly of the tripping mechanism, improves the assembly efficiency, reduces the production cost, and can adapt to different circuit breaking requirements by replacing the elastic member 120. Moreover, through the cooperation of the elastic module 100 and multiple installation slots 310, after adjusting the installation of the elastic module 100 to different installation slots 310, key parameters such as the pre-tightening force and spring constant received by the elastic module 100 can be changed, thereby achieving fine regulation of the reset performance.

[0122] The elastic module 100 of the present application is not limited to switch devices such as circuit breakers, and the elastic module 100 can also be applied to switch devices such as fuses, contactors, and relays.
