Description

Technical Field

[0001] The present application relates to the technical field of circuit breaker production, and in particular to a circuit breaker detection component. Background Art

[0002] During the production process, circuit breakers are subject to multiple tests to check their safety, such as short-circuit tests, peak withstand current tests, or voltage withstand tests, to ensure that their performance and quality meet standards.

[0003] During the withstand voltage test, the circuit breaker housing needs to be grounded and high voltage is applied to the two poles of the circuit breaker to detect the insulation strength of each part of the circuit breaker housing in order to detect potential insulation problems in advance and avoid leakage accidents.

[0004] However, existing withstand voltage testing equipment may fail to detect some structures of the circuit breaker housing during withstand voltage testing. The undetected parts may have leakage hazards. Therefore, it is urgent to propose a detection component to reduce the risk of leakage accidents. Utility Model Content

[0005] The purpose of this application is to provide a circuit breaker detection component that can improve the detection accuracy of the circuit breaker and improve the safety of the circuit breaker.

[0006] An embodiment of the present application provides a circuit breaker detection assembly, wherein the circuit breaker includes a housing, the housing includes a mounting hole, the circuit breaker detection assembly includes a support and a detection probe, the detection probe is arranged on the support, and the detection probe can extend into the mounting hole and detect the mounting hole.

[0007] Based on the above-described embodiments of the present application, by providing a detection probe corresponding to the mounting hole on the circuit breaker housing, the detection probe can be used to perform insulation testing on the housing mounting hole portion, thereby avoiding missed detections, making the withstand voltage testing of the circuit breaker housing more comprehensive, and preventing leakage or electric shock accidents caused by poor insulation performance at the mounting hole, which is beneficial to improving the safety of circuit breaker use.

[0008] In some examples, the detection probe is inserted into the mounting hole and can abut against a wall of the mounting hole.

[0009] Based on the above-mentioned embodiments of the present application, the detection probe abuts against the wall of the mounting hole to detect whether there is leakage at the mounting hole by contact, thereby avoiding accidents such as leakage or electric shock after inserting the screws when installing the circuit breaker, which is beneficial to reducing the safety risks of the circuit breaker itself.

[0010] In some examples, the length of the detection probe is greater than or equal to the depth of the mounting hole.

[0011] Based on the above-mentioned embodiments of the present application, this setting form can make the detection probe fit closely with the mounting hole. The detection probe can be used to detect leakage or blockage in the entire mounting hole, which is conducive to accurately judging whether the circuit breaker can be used normally, avoiding the situation where part of the mounting hole is detected to be normal while the rest has safety hazards, and ensuring comprehensive detection of the circuit breaker.

[0012] In some examples, the mounting hole is configured as a circular hole, the detection probe is configured as a cylindrical shape, and the cylindrical detection probe is adapted to fit the mounting hole.

[0013] Based on the above-mentioned embodiments of the present application, the cylindrical detection probe fits into the circular hole, which facilitates a close fit between the detection probe and the mounting hole. The mounting hole is configured as a circular hole primarily to accommodate the mounting screw. Therefore, the cylindrical detection probe can simulate the fit of the mounting screw with the housing, thereby detecting whether there is leakage in the mounting hole after the mounting screw is inserted, which helps to improve the accuracy of the detection results.

[0014] In some examples, the support member is configured as a support plate, and the detection probe is disposed on the support plate. Alternatively, the support member is configured as a manipulator, and the detection probe is clamped by the manipulator. Alternatively, the support member is configured as a support column, and the detection probe is disposed on the support column.

[0015] Based on the above-mentioned embodiments of the present application, the support member can provide stable support for the detection probe, and at the same time can drive the detection probe to extend into the mounting hole to achieve the cooperation between the detection probe and the mounting hole. Therefore, the setting of the support member is conducive to maintaining the stability of the detection component, thereby improving the detection accuracy of the detection component and ensuring that each mounting hole is fully inspected to obtain accurate detection results.

[0016] In some examples, the detection probe includes a detection portion and a telescopic portion, and the telescopic portion is disposed on a side of the detection portion close to the support member.

[0017] Based on the above-mentioned embodiments of the present application, the detection probe composed of a detection part and a telescopic part can use the telescopic part to adjust the position of the detection part, so that the detection part can be accurately and timely extended into the mounting hole. At the same time, it can also avoid the detection probe from being broken by collision or extrusion, which is beneficial to improving the structural stability of the detection probe.

[0018] In some examples, the telescopic portion is configured as a spring, a first end of the spring is connected to the support member, and a second end of the spring is connected to the detection portion.

[0019] Based on the above-mentioned embodiments of the present application, the use of a spring as the telescopic portion can meet the requirements for telescopic properties while having a simple structure and low production costs. The spring is arranged between the support member and the detection portion. When the detection portion is subjected to pressure, the spring is compressed to prevent damage to the detection probe. When the detection probe is aligned with the mounting hole, the spring is released to drive the detection portion into the mounting hole. This combination is also simple and efficient.

[0020] In some examples, a limiting structure is provided on the support member, and the limiting structure can cooperate with the housing so that the detection probe corresponds to the mounting hole.

[0021] Based on the above-mentioned embodiments of the present application, the limiting structure, in cooperation with the shell, can make the detection probe accurately correspond to the mounting hole, so that the detection probe can smoothly enter the mounting hole.

[0022] In some examples, at least one detection probe is provided, at least one mounting hole is provided on the housing, and the at least one detection probe corresponds to the at least one mounting hole.

[0023] Based on the above-mentioned embodiments of the present application, a single detection probe can be set to detect a single mounting hole or multiple mounting holes. Of course, multiple detection probes can also be set to detect multiple mounting holes at the same time. This can greatly improve the detection efficiency of the detection component and help expand the scope of application of the detection component.

[0024] In some examples, the detection assembly further includes a driving member, the detection probe is directly or indirectly connected to the driving member, and the driving member is capable of driving the detection probe to extend into the mounting hole.

[0025] Based on the above-described embodiments of the present application, the driver is used to drive the detection probe into the mounting hole. The driver can act on the support member to drive the detection probe through the support member, or it can act directly on the detection probe. The driver is configured to provide driving force to the detection probe, which facilitates the detection probe's smooth insertion into the mounting hole and its exit from the mounting hole after the detection of the mounting hole is completed.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0037] In the description of this application, it should be noted that the terms "inner" and "outer" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the components or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0038] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0039] After manufacturing, circuit breakers need to undergo a power frequency withstand voltage test. The power frequency withstand voltage test applies power frequency voltage to the insulation system of the equipment to test the insulation strength of the insulation system under the rated voltage. When applied to circuit breakers, this test can detect the insulation effect and withstand voltage capacity of the circuit breaker housing. This allows the circuit breaker to be checked for insulation defects before it is put into use, thus avoiding leakage or electric shock accidents during use.

[0040] When testing the insulation performance of the circuit breaker housing, the existing technology mostly ignores the detection of the mounting holes on the housing. If insulation defects occur at the mounting holes, there will be a risk of leakage during the use of the circuit breaker, affecting the safety of the circuit breaker.

[0041] Based on this, an embodiment of the present application provides a circuit breaker detection component, which can improve the detection accuracy of the circuit breaker and improve the safety of the circuit breaker.

[0042] 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 with reference to the accompanying drawings.

[0043] Please refer to Figure 1 and Figure 2 This embodiment provides a circuit breaker detection assembly 2, the circuit breaker includes a housing 1, the housing 1 includes a mounting hole 11, the circuit breaker detection assembly 2 includes a support 22 and a detection probe 21, the detection probe 21 is arranged on the support 22, and the detection probe 21 can be extended into the mounting hole 11 and detect the mounting hole 11.

[0044] Based on the above-described embodiments of the present application, by providing a detection probe 21 corresponding to the mounting hole 11 on the circuit breaker housing 1, the detection probe 21 can be used to perform insulation testing on the mounting hole 11 portion of the housing 1, thereby avoiding missed detections and making the withstand voltage testing of the circuit breaker housing 1 more comprehensive. This prevents leakage or electric shock accidents caused by poor insulation performance at the mounting hole 11, thereby improving the safety of the circuit breaker.

[0045] Specifically, the circuit breaker housing 1 serves as the main support for the various electrical components 13 within the circuit breaker, protecting them from damage and preventing accidental electric shock. Mounting holes 11 provided on the housing 1 are used to install the circuit breaker. These are typically secured by screws passing through mounting holes 11 and into pre-set locations.

[0046] The housing 1 is made of insulating material and includes a base and a cover. The base is usually embedded with an insert 12 for connecting the base and the cover during manufacturing. The insert 12 is usually a metal part. The cover and the base can be connected as a whole by screws passing through the cover and connecting to the insert 12. Figure 2 During the manufacturing process of the housing 1, there may be a situation where the insert 12 or other metal impurities block the mounting hole 11 due to manufacturing errors, and even the insert 12 or other metal impurities may short-circuit other electrical components 13 of the circuit breaker.

[0047] By inserting the detection probe 21 in this embodiment into the mounting hole 11, whether the mounting hole 11 is blocked and whether there is leakage in the mounting hole 11 can be detected based on whether the detection probe 21 can be smoothly inserted into the mounting hole 11 and whether the detection probe 21 detects voltage, thereby effectively solving the problem of the circuit breaker not being able to be used normally due to hidden dangers such as blockage or leakage in the mounting hole 11.

[0048] Furthermore, the support member 22 in the circuit breaker detection assembly 2 is used to support the detection probe 21. The support member 22 can provide stable support for the detection probe 21, so that the detection probe 21 can accurately and stably extend into the mounting hole 11, and the support member 22 can also drive the detection probe 21 to move so that the detection probe 21 extends into the mounting hole 11.

[0049] The detection probe 21 can be provided as one or more. When the housing 1 is provided with multiple mounting holes 11, one detection probe 21 can be sequentially inserted into each mounting hole 11 for detection. The arrangement of multiple detection probes 21 can simultaneously detect multiple mounting holes 11, which is conducive to improving detection efficiency.

[0050] Reference Figure 1 In some examples, the detection probe 21 extends into the mounting hole 11 and can abut against the wall of the mounting hole 11 .

[0051] Based on the above-mentioned embodiments of the present application, the detection probe 21 abuts against the hole wall of the mounting hole 11 to detect whether there is leakage at the mounting hole 11 by contact, thereby avoiding accidents such as leakage or electric shock after inserting the screws when installing the circuit breaker, which is beneficial to reducing the safety risks of the circuit breaker itself.

[0052] The detection probe 21 can partially abut against the hole wall of the mounting hole 11, or it can completely abut against the hole wall of the mounting hole 11. Compared with the partial abutment form, the detection accuracy of completely abutting against the hole wall of the mounting hole 11 is higher, which is more conducive to obtaining accurate detection results and avoiding safety hazards of the circuit breaker due to inadequate detection.

[0053] Reference Figure 1 In some examples, the length of the detection probe 21 is greater than or equal to the depth of the mounting hole 11 .

[0054] Based on the above-mentioned embodiments of the present application, this setting form can make the detection probe 21 fit closely with the mounting hole 11. The detection probe 21 can be used to detect leakage or blockage in the entire mounting hole 11, which is conducive to accurately judging whether the circuit breaker can be used normally, avoiding the situation where a part of the mounting hole 11 is detected to be normal while the rest has safety hazards, and ensuring comprehensive detection of the circuit breaker.

[0055] Reference Figures 1 to 3 In some examples, the mounting hole 11 is configured as a circular hole, and the detection probe 21 is configured as a cylindrical shape, and the cylindrical detection probe 21 is adapted to fit the mounting hole 11 .

[0056] Based on the above-mentioned embodiment of the present application, the cylindrical detection probe 21 is adapted to the circular hole, which facilitates a close fit between the detection probe 21 and the mounting hole 11. The mounting hole 11 is configured as a circular hole mainly for adapting to the mounting screw. Therefore, the cylindrical detection probe 21 can simulate the fit of the mounting screw with the housing 1, thereby detecting whether there is leakage in the mounting hole 11 after the mounting screw is inserted, which is conducive to improving the accuracy of the detection result.

[0057] Of course, the mounting hole 11 can also be set to other shapes, such as a square hole or a triangular hole, and the detection probe 21 can be set to a columnar structure corresponding to the shape of the mounting hole 11, and can also be tightly matched with the mounting hole 11, having the same technical effect as the aforementioned embodiment.

[0058] Reference Figure 2 and Figure 3 In some examples, the support member 22 is configured as a support plate, and at least one detection probe 21 is disposed on the support plate.

[0059] Using a support plate as a support member 22 can support a single detection probe 21, or multiple detection probes 21 can be arranged on the support plate at intervals to correspond to the multiple mounting holes 11 set at intervals on the shell 1. The use of a support plate facilitates the simultaneous control of multiple detection probes 21 to detect multiple mounting holes 11, thereby improving detection accuracy and detection efficiency.

[0060] In some examples, the support member 22 is configured as a robot arm, and the at least one detection probe 21 is clamped by the robot arm.

[0061] A manipulator can usually control a single detection probe 21 to detect the mounting hole 11. The manipulator has a high degree of freedom and can control a single detection probe 21 to detect multiple mounting holes 11 in sequence. It can also improve detection efficiency while meeting detection accuracy.

[0062] In some examples, the support member 22 is configured as a support column, and the at least one detection probe 21 is disposed on the support column.

[0063] A support column is used as the support member 22, and the detection probe 21 can be set at the top of the support column. The detection probe 21 can be driven into the mounting hole 11 by the axial movement of the support column. The detection probe 21 can also be set on the side surface of the support column. The detection probe 21 can be driven into the mounting hole 11 by the rotation of the support column. In this way, multiple detection probes 21 can be set at intervals on the support column, which can also improve the detection efficiency.

[0064] Based on the above-mentioned embodiments of the present application, the support member 22 can provide stable support for the detection probe 21, and at the same time can drive the detection probe 21 to extend into the mounting hole 11 to achieve the cooperation between the detection probe 21 and the mounting hole 11. Therefore, the setting of the support member 22 is conducive to maintaining the stability of the detection component 2, thereby improving the detection accuracy of the detection component 2 and ensuring that each mounting hole 11 is fully inspected to obtain accurate detection results.

[0065] Reference Figure 4 In some examples, the detection probe 21 includes a detection portion 211 and a telescopic portion 212 , and the telescopic portion 212 is disposed on a side of the detection portion 211 close to the support member 22 .

[0066] Based on the above-mentioned embodiments of the present application, the detection probe 21 composed of the detection part 211 and the telescopic part 212 can use the telescopic part 212 to adjust the position of the detection part 211, so that the detection part 211 can be accurately and timely extended into the mounting hole 11. At the same time, it can also avoid the detection probe 21 from being broken by collision or extrusion, which is beneficial to improving the structural stability of the detection probe 21.

[0067] Among them, the detection part 211 is arranged at the end of the detection probe 21 away from the support part 22, and the telescopic part 212 is connected between the support part 22 and the detection part 211. The telescopic part 212 can drive the detection part 211 to move along the telescopic direction when it telescopes relative to the support part 22. The telescopic direction is the axial direction of the mounting hole 11. When the detection probe 21 is aligned with the mounting hole 11, the detection part 211 can be controlled to extend into the mounting hole 11 through the telescopic part 212.

[0068] The telescopic portion 212 may be configured as an elastic structure, or as a telescopic structure with a driving device, such as a hydraulic mechanism.

[0069] Reference Figure 4 In some examples, the telescopic portion 212 is configured as a spring, a first end of the spring is connected to the support member 22 , and a second end of the spring is connected to the detection portion 211 .

[0070] Based on the above-mentioned embodiment of the present application, the use of a spring as the telescopic portion 212 can meet the requirements for telescopic properties while having a simple structure and low production costs. The spring is arranged between the support member 22 and the detection portion 211. When the detection portion 211 is subjected to pressure, the spring is compressed to prevent damage to the detection probe 21. When the detection probe 21 is aligned with the mounting hole 11, the spring is released to drive the detection portion 211 into the mounting hole 11. This form of coordination is also simple and efficient.

[0071] Reference Figure 5 In some examples, a limiting structure 221 is provided on the support member 22 , and the limiting structure 221 can cooperate with the housing 1 so that the detection probe 21 corresponds to the mounting hole 11 .

[0072] Based on the above-mentioned embodiments of the present application, the limiting structure 221 , in cooperation with the housing 1 , can make the detection probe 21 accurately correspond to the mounting hole 11 , so that the detection probe 21 can smoothly enter the mounting hole 11 .

[0073] The limiting structure 221 may be a limiting boss provided on the support member 22. When the detection assembly 2 detects the housing 1, the limiting boss abuts against a side wall of the housing 1, thereby limiting the relative position between the support member 22 and the housing 1, so that the detection probe 21 corresponds to the position of the mounting hole 11. At this time, the detection probe 21 can accurately extend into the mounting hole 11 and detect the mounting hole 11. Of course, the limiting structure 221 can also be configured in other forms, such as a limiting groove or a limiting column.

[0074] Reference Figure 4 and Figure 5 In some examples, a plurality of detection probes 21 are provided, a plurality of mounting holes 11 are provided on the housing 1 , the plurality of detection probes 21 are arranged at intervals, and the plurality of detection probes 21 correspond to the plurality of mounting holes 11 one by one.

[0075] Based on the above-mentioned embodiments of the present application, multiple detection probes 21 correspond to multiple mounting holes 11 at the same time, and multiple mounting holes 11 are detected simultaneously, which can greatly improve the detection efficiency of the detection component 2 and is conducive to expanding the scope of application of the detection component 2.

[0076] In this embodiment, the support member 22 is configured as a support plate, four detection probes 21 are provided, and four mounting holes 11 are provided on the circuit breaker housing 1. When the housing 1 is inspected by the detection assembly 2, the four detection probes 21 correspond to the four mounting holes 11, facilitating batch inspection of such circuit breaker housings 1 using the detection assembly 2. Furthermore, the four detection probes 21 can also be applied to circuit breaker housings 1 having only two mounting holes 11, or circuit breaker housings 1 having six or more mounting holes 11, thus providing a wide range of applicability.

[0077] In some examples, the detection assembly 2 further includes a driving member, and the detection probe 21 is directly or indirectly connected to the driving member, and the driving member can drive the detection probe 21 to extend into the mounting hole 11 .

[0078] Based on the above-mentioned embodiment of the present application, the driving member is used to drive the detection probe 21 to extend into the mounting hole 11. The driving member can act on the support member 22 to drive the detection probe 21 to move through the support member 22, or it can directly act on the detection probe 21. The configuration of the driving member provides driving force to the detection probe 21, which facilitates the detection probe 21 to smoothly extend into the mounting hole 11 and to exit the mounting hole 11 after the detection of the mounting hole 11 is completed.

[0079] The driving element can be configured as a driving device such as a servo motor or a stepper motor.

[0080] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
