The drive assembly drives the circuit breaker to move along the preset direction, so that the circuit breaker contact inside the circuit breaker can mate with the positioning contact along the preset direction. If multiple circuit breaker contacts inside the circuit breaker mate with a positioning contact at the same time, it proves that the assembly of the circuit breaker contact and the circuit breaker is qualified. If multiple circuit breaker contacts inside the circuit breaker cannot mate with a positioning contact at the same time, it proves that the assembly of the circuit breaker contact and the circuit breaker body is unqualified. This enables rapid verification of whether the assembly between the circuit breaker contact and the circuit breaker is qualified, with high verification accuracy and high verification efficiency.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] In the circuit breaker manufacturing process, the circuit breaker contacts and the circuit breaker body need to be manufactured separately, and then multiple circuit breaker contacts are assembled together with the circuit breaker body. To ensure the normal operation of the circuit breaker, the assembled circuit breaker contacts and circuit breaker body need to be inspected to ensure that each circuit breaker contact is assembled with the circuit breaker body in a preset position. This assembly inspection requires manual measurement by workers using a measuring tape, comparing the measured dimensions with specified values ​​to determine if the assembly is qualified. This method of assembly inspection is not only time-consuming and labor-intensive, but also inefficient, inaccurate, and prone to errors.

[0049] To solve the above problems, such as Figures 1-5As shown, this embodiment provides a circuit breaker assembly verification device. The circuit breaker assembly verification device includes a base frame 200, a positioning contact 100, and a drive assembly 300. The base frame 200 includes a first mounting base 210 and a second mounting base 220 connected sequentially in a predetermined direction in a horizontal plane. The first mounting base 210 has a protruding portion 211 extending vertically upwards from the upper end face of the second mounting base 220. A circuit breaker 2000 is movably mounted on the upper end of the second mounting base 220. The circuit breaker 2000 located within the circuit breaker 2000 on the second mounting base 220... The contact 2100 approaches the protrusion 211 along a preset direction. Multiple positioning contacts 100 are respectively installed in the first mounting base 210 at preset positions on the end face of the protrusion 211 approaching the second mounting base 220 along a preset direction. Each positioning contact 100 corresponds to a circuit breaker contact 2100. The drive assembly 300 is mounted on the base frame 200. The output terminal of the drive assembly 300 is connected to the circuit breaker 2000. The drive assembly 300 can drive the circuit breaker 2000 to move along a preset direction.

[0050] The circuit breaker assembly and verification device comprises a first mounting base 210 and a second mounting base 220 sequentially connected in a predetermined direction in a horizontal plane within a base frame 200. The first mounting base 210 has a protruding portion 211 extending vertically upwards from the upper end face of the second mounting base 220. A circuit breaker 2000 is mounted on the upper end of the second mounting base 220, with the circuit breaker contact 2100 within the circuit breaker 2000 mounted on the second mounting base 220 positioned near the protruding portion 211 in a predetermined direction. Multiple positioning contacts 100 are respectively installed at predetermined positions on the end face of the protruding portion 211 near the second mounting base 220 in a predetermined direction. That is, if the protruding portion 211 is considered the circuit breaker body of the circuit breaker 2000, and the positioning contacts 100 are considered the circuit breaker contacts 2100, each positioning contact 100 is positioned according to the circuit breaker body and the circuit breaker contact 2100. The specified qualified position is installed on the end face of the protruding part 211 near the second mounting base 220 along a preset direction, so that the output end of the drive assembly 300 is connected to the circuit breaker 2000. The drive assembly 300 drives the circuit breaker 2000 to move along the preset direction, so that the circuit breaker contacts 2100 in the circuit breaker 2000 can mate with the positioning contacts 100 along the preset direction. If multiple circuit breaker contacts 2100 in the circuit breaker 2000 mate with one positioning contact 100 at the same time, it proves that the assembly of the circuit breaker contacts 2100 and the circuit breaker body is qualified. If multiple circuit breaker contacts 2100 in the circuit breaker 2000 cannot mate with one positioning contact 100 at the same time, it proves that the assembly of the circuit breaker contacts 2100 and the circuit breaker body is unqualified. This achieves rapid verification of whether the assembly between the circuit breaker contacts 2100 and the circuit breaker body is qualified, with high verification accuracy and efficiency. It should be noted that in this embodiment, the preset direction is the left-right direction. In other embodiments, the direction of the preset direction can be adjusted according to actual needs, as long as the preset direction is parallel to the horizontal plane. This embodiment does not impose any specific limitations.

[0051] Furthermore, in this embodiment, the circuit breaker 2000 contains a total of six circuit breaker contacts 2100. Therefore, the circuit breaker assembly and verification device contains a total of six positioning contacts 100. These six positioning contacts 100 are respectively installed on the end face of the extended portion 211, close to the second mounting base 220, in a predetermined direction according to the specified qualified positions of the circuit breaker body and the circuit breaker contacts 2100. In other embodiments, the specific number of positioning contacts 100 can be adaptively adjusted according to the specific number of circuit breaker contacts 2100 within the circuit breaker 2000; this embodiment does not impose a specific limitation.

[0052] As an optional solution, such as Figure 5As shown, the drive assembly 300 includes a lead screw 310, a fixed base 320, and a nut (not shown). The lead screw 310 extends along a preset direction, the fixed base 320 is fixed to the base frame 200, and the lead screw 310 and the fixed base 320 are rotatably connected about the axial direction of the lead screw 310. The nut is fixed at the circuit breaker 2000, and the nut is threadedly engaged with the lead screw 310. By fixing the fixed base 320 to the base frame 200 and rotatably connecting the lead screw 310 extending along the preset direction to the fixed base 320 about the axial direction of the lead screw 310, combined with the threaded engagement of the nut fixed at the circuit breaker 2000 with the lead screw 310, the circuit breaker 2000 can be driven to move along the preset direction during the axial rotation of the lead screw 310 relative to the fixed base 320. When it is necessary to drive the circuit breaker 2000 to move towards the end closer to the positioning contact 100 along the preset direction, the lead screw 310 rotates forward relative to the fixed base 320. When it is necessary to drive the circuit breaker 2000 to move in a preset direction toward the end away from the positioning contact 100, the drive screw 310 rotates in the opposite direction relative to the fixed base 320.

[0053] Specifically, such as Figure 3 , Figure 4 , Figure 6 as well as Figure 7 As shown, the base frame 200 also includes a third mounting base 230, which is fixed to the upper end of the first mounting base 210. The third mounting base 230 supports the circuit breaker 2000, and a snap-fit ​​groove 2311 is formed on the upper end surface of the third mounting base 230. The snap-fit ​​groove 2311 is snapped and fixed to the fixed base 320. By forming the third mounting base 230 at the upper end of the first mounting base 210 and forming the snap-fit ​​groove 2311 on the upper end surface of the third mounting base 230, the fixed base 320 can be snapped and fixed to the snap-fit ​​groove 2311, thereby achieving the clamping and fixing of the fixed base 320 relative to the base frame 200 and ensuring the normal rotation of the lead screw 310.

[0054] To improve the engagement efficiency between the fixing seat 320 and the snap-fit ​​slot 2311, such as Figure 8 As shown, the snap-fit ​​groove 2311 includes a guide portion 23111 and a snap-fit ​​portion 23112 connected sequentially from top to bottom. The width of the guide portion 23111 gradually decreases from top to bottom along a preset direction, and the minimum width of the guide portion 23111 along the preset direction is equal to the width of the snap-fit ​​portion 23112 along the preset direction. The snap-fit ​​portion 23112 is configured to snap-fit ​​and fix with the fixing seat 320. When it is necessary to snap-fit ​​and fix the fixing seat 320 to the snap-fit ​​groove 2311, the fixing seat 320 is slid into the snap-fit ​​portion 23112 along the guide portion 23111, reducing the difficulty of docking the fixing seat 320 and the snap-fit ​​portion 23112, thereby improving the snap-fit ​​efficiency between the fixing seat 320 and the snap-fit ​​groove 2311.

[0055] In this embodiment, the third mounting base 230 includes two support beams 231 extending along a preset direction. The two support beams 231 are respectively fixed to both ends of the second mounting base 220 along a first direction. Each support beam 231 has a snap-fit ​​groove 2311, and the two snap-fit ​​grooves 2311 are snapped together with the fixing base 320. The first direction is parallel to the horizontal plane and perpendicular to the preset direction. By including two support beams 231 extending along the preset direction in the third mounting base 230, and placing the two support beams 231 at both ends of the second mounting base 220 along the first direction, ensuring that the first direction is parallel to the horizontal plane and perpendicular to the preset direction, and by providing snap-fit ​​grooves 2311 on each support beam 231, the two support beams 231 can be snapped together with the fixing base 320 from both ends of the first direction, improving the snap-fit ​​stability of the fixing base 320.

[0056] It should be noted that in this embodiment, since the preset direction is left-right, the first direction is front-back. In other embodiments, the specific direction of the first direction can be adaptively adjusted according to the specific direction of the preset direction.

[0057] Combination Figure 5 The specific structure of the fixing base 320 is described below. The fixing base 320 has locking protrusions 321 on both ends along the first direction. Each locking protrusion 321 is locked and fixed with a locking groove 2311 along a preset direction. The two ends of the fixing base 320 along the first direction abut against the support beam 231. By providing locking protrusions 321 on both ends of the fixing base 320 along the first direction, and having each locking protrusion 321 locked and fixed with a locking groove 2311, and having both ends of the fixing base 320 abut against the support beam 231, the locking and fixing effect of the fixing base 320 is further improved, as it can be locked and fixed along the first direction using both the locking groove 2311 and the two support beams 231.

[0058] In addition, such as Figure 1 As shown, each support beam 231 is provided with a rolling groove 2312 extending in a preset direction, and each rolling groove 2312 is in rolling engagement with the roller 2200 inside the circuit breaker 2000. By providing a rolling groove 2312 extending in a preset direction in each support beam 231, the rolling groove 2312 is in rolling engagement with the roller 2200 inside the circuit breaker. When the lead screw 310 drives the circuit breaker 2000 to move in the preset direction, the roller 2200 can roll along the rolling groove 2312, thereby replacing the sliding of the circuit breaker 2000 relative to the support beam 231 with the rolling of the circuit breaker 2000 relative to the support beam 231, reducing the friction between the circuit breaker 2000 and the support beam 231.

[0059] In this embodiment, as Figure 5 As shown, the drive assembly 300 also includes a handle 330, which is coaxially fixed to the lead screw 310. The surface of the handle 330 is provided with grooves and protrusions. By additionally equipping the drive assembly 300 with a handle 330 coaxially fixed to the lead screw 310, it is easier for the operator to drive the lead screw 310 to rotate around its own axis. The grooves and protrusions on the surface of the handle 330 make it easier for the operator to grip the handle 330, improving the stability of the operator's grip on the handle 330.

[0060] Combination Figure 9 The specific structure of the positioning contact 100 is described below. The positioning contact 100 includes a connecting part 110 and an abutting part 120. The connecting part 110 is fixedly connected to the end face of the protruding part 211 that is close to the second mounting base 220 in a preset direction. The abutting part 120 is fixedly connected to one end of the connecting part 110 that is close to the second mounting base 220 in a preset direction. The abutting part 120 can abut against the circuit breaker contact 2100. During the repeated contact between the circuit breaker contact 2100 and the positioning contact 100, the positioning contact 100 is prone to damage. By disassembling the positioning contact 100 into a detachable connecting part 110 and an abutting part 120, the connecting part 110 is fixedly connected to the protruding part 211, and the abutting part 120 abuts against the circuit breaker contact 2100. When the abutting part 120 or the connecting part 110 is damaged, only the damaged abutting part 120 or the connecting part 110 can be replaced, without replacing the entire positioning contact 100, thus saving costs.

[0061] Furthermore, in this embodiment, the end of the abutment portion 120 near the second mounting base 220 along a preset direction is covered with an elastic buffer layer. By covering the end of the abutment portion 120 near the second mounting base 220 along a preset direction with an elastic protective layer, when the abutment portion 120 abuts against the circuit breaker contact 2100, the elastic buffer layer can be sandwiched between the abutment portion 120 and the circuit breaker contact 2100, providing buffering for the impact between the abutment portion 120 and the circuit breaker contact 2100, and improving the protection of the abutment portion 120 and the circuit breaker contact 2100. It should be noted that in this embodiment, the elastic buffer layer is made of rubber material. Rubber material has good elasticity, toughness, and wear resistance, and has a long service life. In other embodiments, the elastic buffer layer can also be supported by sponge, cotton, or other elastic materials; this embodiment does not make specific limitations.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
