Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and more specifically, to a connection assembly for a circuit breaker switch. Background Technology

[0002] Currently, in circuit breaker switches, the conductive connecting piece is fitted onto the threaded socket head by its annular tail end, and the other end of the conductive connecting piece is welded to the connection end of the shunt device. This achieves the conductive connection and shunt function between the shunt device and the various components in the circuit breaker. However, the method of fitting the annular tail end of the conductive connecting piece onto the socket head thread can easily lead to misalignment of the shunt device, resulting in inaccurate positioning and affecting the automated assembly efficiency of the circuit breaker. On the other hand, the welded connection between the conductive connecting piece and the shunt device can experience incomplete soldering or detachment, which can lead to circuit breaker failure.

[0003] Therefore, there is an urgent need to develop a circuit breaker switch connection assembly to solve at least one of the following problems of existing connection assemblies: inaccurate positioning, poor soldering, desoldering, low efficiency of automated assembly of circuit breakers, and insufficient service life. Summary of the Invention

[0004] In view of one of the deficiencies in the prior art, the purpose of this application is to provide a connection component for a circuit breaker switch.

One end of the first connecting plate is provided with a fixing part extending to both sides and connected to the connecting part. One end of the second connecting plate is provided with a second through hole and connected to the positioning boss. During connection, the fixing part of the first connecting plate can be bent in opposite directions to wrap the connecting part of the shunt device. After the fixing part is bent, it is embedded in the first through hole and pressure is applied to the embedded part to complete the connection, forming a connection similar to a snap ring type riveting connection.

[0006] Optionally, the first connecting plate has a "T" shaped structure.

[0007] Optionally, the cross-sectional shape of the second through hole is a polygonal structure.

[0008] Optionally, the cross-sectional shape of the positioning boss is the same as the cross-sectional shape of the second through hole.

[0010] Optionally, the first connecting plate and the second connecting plate are integrally formed.

[0011] Optionally, the socket head assembly includes a bent connecting plate, and the positioning boss is disposed on the bent connecting plate and can extend into the second through hole of the second connecting plate for riveting connection, thereby limiting the position of the conductive connector.

[0012] Optionally, the socket assembly further includes a socket head and a locking member; One end of the socket head is provided with an external thread, and the bent connecting plate is provided with a threaded hole, and one end of the socket head can extend into the threaded hole; The socket head is connected to the bent connecting plate via the locking member.

[0014] This application provides a connecting assembly for a circuit breaker switch, employing a novel technique combining a shunt device and a conductive connector.

This achieves a reliable circuit connection between the socket head and the shunt device, enhancing the consistency of the circuit breaker's quality. Furthermore, by providing a positioning boss on the socket head assembly, which is riveted to the second through hole of the conductive connector, replacing the existing method of attaching the annular end of the conductive connector to the socket head assembly connecting plate, the shunt device is accurately positioned, preventing component misalignment and improving the overall efficiency of the circuit breaker, resulting in significant economic benefits.

[0017] The present application will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present application, and these all fall within the protection scope of the present application. Parts not described in detail in the following embodiments can be implemented using existing technology.

They are only for the convenience of describing this application and simplifying the description, 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 application.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0020] In the description of the embodiments in this application, "multiple" means two or more, unless otherwise explicitly specified. In this application, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," etc., should be interpreted broadly.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or devices.

[0022] In existing technology, circuit breaker switches include shunt devices and socket heads. The conductive connecting piece is connected to the threaded end of the socket head by fitting its annular tail end onto the threaded end of the socket head, and the other end of the conductive connecting piece is welded to the connection end of the shunt device, thus achieving conductive connection and shunt function between the shunt device and the various components in the circuit breaker. However, the method of fitting the annular tail end of the conductive connecting piece onto the threaded end of the socket head can easily lead to misalignment of the shunt device, resulting in inaccurate positioning and affecting the automated assembly efficiency of the circuit breaker. Furthermore, the welded connection between the conductive connecting piece and the shunt device can experience incomplete soldering or detachment, leading to circuit breaker failure. Based on these problems, this application provides a connecting assembly for circuit breaker switches to solve these issues.

[0023] Reference Figure 1 As shown in one embodiment of this application, a connection assembly for a circuit breaker switch includes: a shunt device 1, a conductive connector 2, and a socket assembly 3.

[0024] The current shunt device 1 and the socket assembly 3 are connected by a conductive connector 2; the current shunt device 1 is provided with a connecting part 12, the connecting part 12 is provided with a first through hole 4, and the socket assembly 3 is provided with a positioning boss 10.

[0025] The conductive connector 2 includes a first connecting plate 5 and a second connecting plate 6. One end of the first connecting plate 5 is provided with a fixing part 15 extending to both sides and connected to the connecting part 12. One end of the second connecting plate 6 is provided with a second through hole 16 and connected to the positioning boss 10.

[0026] During connection, the fixing part 15 of the first connecting plate 5 can be bent in opposite directions to wrap the connecting part 12 of the shunt device 1. After the fixing part 15 is bent, it is embedded in the first through hole 4, and pressure is applied to the embedded part to complete the connection, forming a connection similar to a snap ring type riveting connection.

[0027] Specifically, when the current shunt device 1 and the socket assembly 3 are connected by the conductive connector 2, one end of the first connecting plate 5 of the conductive connector 2 is provided with a fixing part 15 extending to both sides, and the fixing parts 15 on both sides are bent in opposite directions to wrap around the connecting part 12 on the current shunt device 1. After the fixing part 15 is bent, it extends into the first through hole 4 on the connecting part 12. Pressure is applied to the embedded part by riveting equipment or tools to make it plastically deformed, forming a riveting connection similar to a snap ring. At the same time, the second connecting plate 6 of the conductive connector 2 is provided with a second through hole 16, which is riveted to the positioning boss 10 on the socket assembly 3 to restrict the position of the conductive connector 2 and prevent the conductive connector 2 from deflecting, so as to realize the automatic assembly and installation of the connecting components.

[0028] It should be noted that the fixing part 5 can be bent in opposite directions within the same bending direction.

[0029] In the above embodiments of this application, the original welding method is replaced by a snap-fit ​​connection between the conductive connector 2 and the shunt device 1, which improves the problems of insufficient service life caused by the original circuit breaker due to desoldering and poor welding. This achieves a good circuit connection between the socket assembly 3 and the shunt device 1, and improves the quality consistency of the circuit breaker. By setting a positioning boss 10 on the socket assembly 3 and riveting it to the second through hole 16 of the conductive connector 2, the existing method of sleeved the circular tail end of the conductive connector piece onto the connecting plate of the socket assembly 3 is replaced. This ensures accurate positioning of the shunt device 1, prevents component deflection, improves the combination efficiency of the circuit breaker, and has significant economic benefits.

[0030] In this process, a snap ring is typically an elastic ring-shaped part that can be engaged in a specific groove or hole to provide fixation and positioning. Riveting is a process that uses external force to cause plastic deformation of the material, thereby connecting parts. In this application, after the bent fixing part 5 is embedded in the first through hole 4, it generates a certain frictional force and mechanical engagement force with the hole wall of the first through hole 4, preventing the fixing part 5 from coming out of the first through hole 4, just like a snap ring is engaged in a groove, ensuring the reliability of the connection. In the riveting connection, pressure is applied to the fixing part 5 embedded in the first through hole 4, causing it to undergo plastic deformation, filling the space inside the first through hole 4, forming a tight mechanical connection, so that the fixing part 5 is tightly combined with the connecting part 12 of the shunt device, forming a form similar to a snap ring-type riveting connection. Only two main steps, bending and riveting, are required, which improves production efficiency and enhances the strength and stability of the connection.

[0031] Secondly, a positioning boss 10 is provided on the socket head assembly 3, which is riveted to the second through hole 16 of the conductive connector 2. That is, after the positioning boss 10 is inserted into the second through hole 16, pressure is applied to the positioning boss 5 by the riveting equipment to make it plastically deform and fill the space in the second through hole 16, so as to achieve connection by riveting.

[0032] In some specific embodiments of this application, the first connecting plate 5 is a "T" shaped structure.

[0033] In the above embodiments of this application, by setting the first connecting plate 5 as a "T" shaped structure, the first connecting plate 5 of the conductive connector 2 can wrap the first through hole 4 of the connecting part 12 of the shunt device 1, and the riveting position is fixed in advance before riveting connection is performed. This effectively improves the problem of easy desoldering between the original welded conductive connector 2 and the shunt device 1, and improves the quality consistency of the connection components.

[0034] In some specific embodiments of this application, the cross-sectional shape of the second through hole 16 is a polygonal structure.

[0035] It should be noted that the cross-sectional shape of the second through hole 16 can be any one of rectangle, ellipse, T-shape or polygon.

[0036] In some specific embodiments of this application, the cross-sectional shape of the positioning boss 10 is the same as the cross-sectional shape of the second through hole 16.

[0037] In the above embodiments of this application, by setting the cross-sectional shape of the positioning boss 10 to be the same as the cross-sectional shape of the second through hole 16, a good riveting connection is achieved between the conductive connector 2 and the bent connecting plate 9.

[0038] In some specific embodiments of this application, the other end of the first connecting plate 5 of the conductive connector 2 is connected to the other end of the second connecting plate 6; the first connecting plate 5 and the second connecting plate 6 are arranged at an angle, parallel or perpendicular to each other.

[0039] It should be noted that the positional relationship between the first connecting plate 5 and the second connecting plate 6 after connection needs to be set according to the layout of the various components inside the circuit breaker, and there is no restriction on the positional relationship described above as being at an angle, parallel or perpendicular.

[0040] For example: refer to the appendix Figures 1 to 2 As shown, in a specific embodiment, a bending member 11 may be provided between the first connecting plate 5 and the second connecting plate 6 of the conductive connector 2; the vertical edge of the other end of the first connecting plate 5 is connected to one end of the bending member 11, and one end of the second connecting plate 6 is connected to the other end of the bending member 11.

[0041] By setting a bending member 11 between the first connecting plate 5 and the second connecting plate 6, the distance between the first connecting plate 5 and the second connecting plate 6 is increased, avoiding interference or poor contact caused by close proximity when the current shunt device 1 and the socket assembly 3 are connected, thus improving the stability and reliability of the connection.

[0042] Based on the above example, the first connecting plate 5 and the second connecting plate 6 are parallel to each other on the bending member 11. By making the first connecting plate 5 and the second connecting plate 6 parallel to each other on the bending member 11, the layout of the current shunt device 1 and the socket assembly 3 during connection is more reasonable, avoiding misalignment, jamming, etc. during connection due to component tilting or non-parallelism, improving the reliability and stability of the connection, and reducing the probability of connection failure.

[0043] In some specific embodiments of this application, the first connecting plate 5 and the second connecting plate 6 are integrally formed.

[0044] In some specific embodiments of this application, the socket head assembly 3 includes a bent connecting plate 9, and a positioning boss 10 is disposed on the bent connecting plate 9, which can extend into the second through hole 16 of the second connecting plate 6 for riveting connection, thereby limiting the position of the conductive connector 2.

[0045] In the above embodiments of this application, by setting a positioning boss 10 on the bent connecting plate 9 of the plug socket assembly and connecting the positioning boss 10 to the second through hole 16 on the conductive connector 2, the conductive connector 2 is less likely to deflect at an angle when connected to the plug socket assembly, thereby better positioning the plug socket assembly connected to the conductive connector 2 and making the position between each part more stable.

[0046] In some specific embodiments of this application, the bent connecting plate 9 includes: a bent section 13 and a non-bent section 14; one end of the non-bent section 14 is connected to one end of the bent section 13; a threaded hole is provided in the non-bent section 14, and a positioning boss 10 is provided in the bent section 13.

[0047] In some specific embodiments of this application, the socket head assembly 3 also includes a socket head 7 and a locking member 8.

[0048] One end of the socket head 7 is provided with an external thread, and the bent connecting plate 9 is provided with a threaded hole, into which one end of the socket head 7 can be inserted; the socket head 7 and the bent connecting plate 9 are connected by a locking member 8.

[0049] Specifically, the socket head 7 is fitted with a connecting locking piece 8 and then threadedly connected to the non-bent section 14 of the bent connecting plate 9; the outer surface of the bent section 13 of the bent connecting plate 9 is provided with a positioning boss 10. The function of the positioning boss 10 is to fix the position of the conductive connector 2 and the current shunt device 1 riveted to the conductive connector 2, so as to prevent the current shunt device 1 from deflecting at an angle during automated assembly.

[0050] It should be noted that locking component 8 is a hexagonal locking component.

[0051] The connection components of the above embodiments of this application are simple to install and easy to operate. Compared with the prior art, the assembly efficiency of the shunt device 1 connection component for circuit breaker switches using the above embodiments of this application is improved by 20%.

[0052] The preferred features in the above embodiments can be used individually in any embodiment, or in any combination thereof, provided they do not conflict with each other. Furthermore, parts not described in detail in the embodiments can be implemented using existing technologies.

[0053] The foregoing has described some specific embodiments of this application. It should be understood that this application is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this application. The above-described preferred features can be used in any combination without conflict.
