Description

Technical Field

[0001] This application relates to the field of switching electrical technology, and more specifically, to a pluggable controller assembly and a circuit breaker. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions and closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. With the continuous development of the power industry, circuit breakers are widely used, which in turn places more stringent requirements on their design and production, such as intelligence, miniaturization, long mechanical life, and ease of disassembly and maintenance.

[0003] Currently, when replacing the controller on a circuit breaker, the circuit breaker's cover needs to be removed, and the screws securing the cover need to be removed as well. Similarly, installing the controller onto the circuit breaker also requires securing it with screws. This installation method involves loosening or tightening a large number of screws during the process, wasting a significant amount of time and labor during large-scale replacements. Summary of the Invention

[0004] The purpose of this application is to provide a pluggable controller assembly and circuit breaker that simplifies the setup and improves operational efficiency when replacing or maintaining the controller.

[0005] The embodiments of this application are implemented as follows:

[0006] One aspect of this application provides a pluggable controller assembly, including a base plate, a housing, and a first sleeve and a second sleeve disposed within the housing. A first operating member is axially slidably connected to the first sleeve, and a second operating member is axially slidably connected to the second sleeve. The housing also provides a locking assembly that respectively cooperates with the first and second operating members. When the first operating member rotates, it can drive the first sleeve to rotate synchronously, so that the first sleeve can engage or disengage with the housing and the base plate respectively. When the second operating member rotates, it can drive the second sleeve to rotate synchronously, so that the second sleeve can engage or disengage with the housing and the base plate respectively. Furthermore, the first and second operating members can be locked or unlocked with the locking assembly respectively, thereby restricting the axial sliding and radial rotation of the first and second operating members.

[0011] Optionally, the locking assembly includes a locking body connected to the housing and a guide post elastically and slidably connected to the locking body. The guide post is provided with a first latch and a second latch. The first latch and the second latch respectively cooperate with the guide post so that the first latch and the second latch move closer to or further away from each other.

[0012] Optionally, the pluggable controller assembly further includes a micro switch disposed on the base plate, and the second sleeve is also provided with a pressure rod that cooperates with the micro switch. When the second sleeve is disengaged from the base plate, the pressure rod causes the micro switch to close. The micro switch is used to connect with a trip unit to control the trip unit's operation.

[0013] Optionally, the housing is provided with a first slot and a second slot, the first slot corresponding to the first handle so that the first handle is embedded in the first slot; the second slot corresponding to the second handle so that the second handle is embedded in the second slot.

[0015] In another aspect of this application, a circuit breaker is provided, including a pluggable controller assembly as described in any one of the above claims. The circuit breaker includes a faceplate with a slot so that the pluggable controller assembly can be embedded in the slot.

[0016] The beneficial effects of the embodiments of this application include:

[0017] The pluggable controller assembly and circuit breaker provided in this application embodiment, through a housing and a first sleeve and a second sleeve disposed within the housing, allow for a desired snap-fit ​​relationship between the housing and the base plate. When snap-fit ​​engagement is required, a first operating member connected to the first sleeve rotates the first sleeve, and a second operating member connected to the second sleeve rotates the second sleeve, thus achieving the desired snap-fit ​​relationship. To disengage the engagement, simply rotate back to the initial position. Furthermore, to ensure stability after engagement, the first operating member slides along the first sleeve, and the second operating member slides along the second sleeve, locking the first and second operating members to a locking assembly, thereby restricting their rotation and preventing them from slipping off the locking assembly. To disengage the housing from the base plate, the locking assembly first unlocks the first and second operating members, allowing them to return to their rotating and sliding states, which in turn moves the first and second sleeves to disengage the engagement. Using the above method, when connection or replacement is required, there is no need to loosen or tighten a large number of screws. The required plugging and unplugging operations can be directly achieved through the first and second operating components, which simplifies the setup and improves the operational efficiency when replacing and maintaining the controller.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0033] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] Currently, replacing the controller on a circuit breaker requires removing the circuit breaker's cover, which in turn requires removing the screws securing the cover. Similarly, installing the controller on the circuit breaker also requires screws. This installation method necessitates loosening or tightening a large number of screws during operation, resulting in significant time waste and high labor intensity during large-scale replacements. To address these issues, this application's embodiment employs the following method, which simplifies the setup and improves the operational efficiency of replacing and maintaining the controller.

[0036] Please refer to Figure 1 and Figure 2 This embodiment provides a pluggable controller assembly 100, including a base plate 110, a housing 120, and a first sleeve 122 and a second sleeve 124 disposed within the housing 120. A first operating member 130 is axially slidably connected to the first sleeve 122, and a second operating member 140 is axially slidably connected to the second sleeve 124. The housing 120 also includes locking components 150 that respectively cooperate with the first operating member 130 and the second operating member 140. Please refer to [further details omitted]. Figure 3 and Figure 4 When the first operating member 130 rotates, it can drive the first sleeve 122 to rotate synchronously, so that the first sleeve 122 can be engaged or disengaged from the housing 120 and the base plate 110 respectively; when the second operating member 140 rotates, it can drive the second sleeve 124 to rotate synchronously, so that the second sleeve 124 can be engaged or disengaged from the housing 120 and the base plate 110 respectively, and the first operating member 130 and the second operating member 140 can be locked or unlocked with the locking assembly 150 respectively, so as to restrict the axial sliding and radial rotation of the first operating member 130 and the second operating member 140.

[0037] Specifically, the controller body is located inside the housing 120, and a circuit board is typically mounted on the base plate 110. Once the housing 120 and the base plate 110 are properly fitted together, the controller body and the circuit board can establish the required electrical connection through connection terminals. Using this connection method, when it is necessary to snap the housing 120 and the base plate 110 together to form a stable connection, or to make contact snap-fit ​​the housing 120 and the base plate 110 together to facilitate insertion and removal of the controller body, the first operating member 130 can rotate the first sleeve 122, and the second operating member 140 can rotate the second sleeve 124. When the first sleeve 122 and the second sleeve 124 rotate, the required snap-fit ​​or release can be achieved at specific angles, thus allowing for the next operation.

[0038] When the first operating member 130 drives the first sleeve 122 to rotate, and the second operating member 140 drives the second sleeve 124 to rotate, so that the housing 120 and the base plate 110 are engaged through the first sleeve 122 and the second sleeve 124, in order to prevent the first operating member 130 or the second operating member 140 from rotating arbitrarily and affecting the stability of the engagement, the first operating member 130 can be pushed to slide along the first sleeve 122 until the first operating member 130 locks with its corresponding locking component 150. At the same time, the second operating member 140 is pushed to slide along the second sleeve 124 until the second operating member 140 locks with its corresponding locking component 150. In this way, axial sliding and radial rotation of the first operating member 130 and the second operating member 140 can be prevented, which helps to ensure the stability of the current state. When it is necessary to release the latch between the housing 120 and the base plate 110, the locking component 150 is controlled to release the lock on the first operating member 130 and the second operating member 140. The first sleeve 122 and the second sleeve 124 can be rotated to the position where the latch is released by rotating the first operating member 130 and the second operating member 140, so that the required insertion and removal operation can be realized.

[0039] The pluggable controller assembly 100 provided in this application embodiment, through a housing 120 and a first sleeve 122 and a second sleeve 124 disposed within the housing 120, allows the housing 120 and the base plate 110 to achieve the required snap-fit ​​relationship through the first sleeve 122 and the second sleeve 124. When the snap-fit ​​is required, the first operating member 130 connected to the first sleeve 122 drives the first sleeve 122 to rotate, and the second operating member 140 connected to the second sleeve 124 drives the second sleeve 124 to rotate, thus achieving the required snap-fit ​​relationship. When the snap-fit ​​needs to be released, simply rotate it back to the initial position. Furthermore, to ensure stability after the snap-fit ​​engagement, the first operating member 130 is slid along the first sleeve 122, and the second operating member 140 is slid along the second sleeve 124, thereby locking the first and second operating members 130 and 140 respectively with the locking assembly 150. This restricts the rotation of the first and second operating members 130 and 140 and prevents them from slipping off the locking assembly 150. When it is necessary to release the snap-fit ​​relationship between the housing 120 and the base plate 110, the first and second operating members 130 and 140 are first unlocked by the locking assembly 150, allowing them to resume their rotation and sliding states. This, in turn, drives the first and second sleeves 122 and 124 to move, thus releasing the snap-fit ​​relationship. Using the above method, when connection or replacement is required, there is no need to loosen or tighten a large number of screws. The required plugging and unplugging operations can be directly achieved through the first operating element 130 and the second operating element 140, which simplifies the setup and improves the operational efficiency when replacing and maintaining the controller.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown, the first operating member 130 includes a first connecting rod 132 slidably connected to the first sleeve 122, and a first handle 134 provided at the end of the first connecting rod 132 away from the first sleeve 122, and a first latch 136 provided on the first handle 134 to cooperate with the locking component 150; the second operating member 140 includes a second connecting rod 142 slidably connected to the second sleeve 124, and a second handle 144 provided at the end of the second connecting rod 142 away from the second sleeve 124, and a second latch 146 provided on the second handle 144 to cooperate with the locking component 150.

[0041] Specifically, the first connecting rod 132 passes through the first sleeve 122, allowing the first operating member 130 to be slidably connected to the first sleeve 122 via the first connecting rod 132. By providing a first handle 134 on the first connecting rod 132, a force can be applied to the first handle 134 when the first operating member 130 rotates the first sleeve 122, making the operation more convenient. Additionally, first latches 136 can be located on opposite sides of the first handle 134, allowing the first operating member 130 to engage with the locking assembly 150 via the two latches 136 respectively. Similarly, the second connecting rod 142 passes through the second sleeve 124, allowing the second operating member 140 to be slidably connected to the second sleeve 124 via the second connecting rod 142. By providing a second handle 144 on the second connecting rod 142, a force can be applied to the second handle 144 when the second operating member 140 rotates the second sleeve 124, making the operation more convenient. Additionally, the second latches 146 can be positioned on opposite sides of the second handle 144, allowing the second operating member 140 to engage with the locking assembly 150 via the two second latches 146 respectively. This configuration improves the reliability of the connection.

[0042] like Figure 6 and Figure 7 As shown, the outer ring of the first sleeve 122 is provided with a first boss 1222 and a second boss 1224, the outer ring of the second sleeve 124 is provided with a first protrusion 1242 and a second protrusion 1244, the housing 120 is provided with two first grooves that respectively cooperate with the first boss 1222 and the first protrusion 1242, and the bottom plate 110 is provided with two second grooves that respectively cooperate with the second boss 1224 and the second protrusion 1244.

[0043] Specifically, a first protrusion 1222 is provided on the outer ring of the first sleeve 122, and the first protrusion 1222 is engaged with the first groove. When the first sleeve 122 rotates, the first protrusion 1222 rotates synchronously with the first sleeve 122, so that the first protrusion 1222 can disengage from the limiting effect of the first groove at a specific position. Similarly, a first protrusion 1242 is provided on the outer ring of the second sleeve 124, and the first protrusion 1242 is engaged with the first groove. When the second sleeve 124 rotates, the first protrusion 1242 rotates synchronously with the second sleeve 124, so that the first protrusion 1242 can disengage from the limiting effect of the first groove at a specific position. The connection between the first sleeve 122 and the base plate 110 via the second protrusion 1224, and the connection between the second sleeve 124 and the base plate 110 via the second protrusion 1244, are the same as the connection between the first sleeve 122 and the housing 120 in the above embodiment, and will not be described again here.

[0044] like Figure 5 , Figure 6 and Figure 7 As shown, the inner ring of the first sleeve 122 is provided with a first sliding groove 1226, the extension direction of the first sliding groove 1226 is consistent with the extension direction of the first sleeve 122, and the first connecting rod 132 is provided with a first elastic pin 138 that is engaged with the first sliding groove 1226; the inner ring of the second sleeve 124 is provided with a second sliding groove 1246, the extension direction of the second sliding groove 1246 is consistent with the extension direction of the second sleeve 124, and the second connecting rod 142 is provided with a second elastic pin 148 that is engaged with the second sliding groove 1246.

[0045] Specifically, by providing a first sliding groove 1226 on the inner ring of the first sleeve 122 and a first elastic pin 138 on the first connecting rod 132 that engages with the first sliding groove 1226, the first elastic pin 138 enables a locking engagement between the first connecting rod 132 and the first sleeve 122. While allowing relative sliding along the axial direction, the rotation of the first connecting rod 132 drives the first sleeve 122 to rotate, thus achieving a simple pluggable / pluggable mechanism for the controller body. Similarly, by providing a second sliding groove 1246 on the inner ring of the second sleeve 124 and a second elastic pin 148 on the second connecting rod 142 that engages with the second sliding groove 1246, the second elastic pin 148 enables a locking engagement between the second connecting rod 142 and the second sleeve 124. While allowing relative sliding along the axial direction, the rotation of the second connecting rod 142 drives the second sleeve 124 to rotate, achieving a simple pluggable / pluggable mechanism for the controller body.

[0046] In an optional embodiment of this application, the inner ring of the first sleeve 122 is provided with a first sliding groove 1226, the extension direction of the first sliding groove 1226 is consistent with the extension direction of the first sleeve 122, the first connecting rod 132 is provided with a first sliding sleeve, the outer ring of the first sliding sleeve is provided with a first protrusion that engages with the first sliding groove 1226; the inner ring of the second sleeve 124 is provided with a second sliding groove 1246, the extension direction of the second sliding groove 1246 is consistent with the extension direction of the second sleeve 124, the second connecting rod 142 is provided with a second sliding sleeve, the outer ring of the second sliding sleeve is provided with a second protrusion that engages with the second sliding groove 1246.

[0047] Specifically, the first connecting rod 132 and the first sliding sleeve can be fixed together by a threaded connection, and the first protrusion on the outer ring of the first sliding sleeve is engaged in the first sliding groove 1226. This allows for relative sliding along the axial direction, and the rotation of the first connecting rod 132 can drive the rotation of the first sleeve 122, thus achieving the aforementioned purpose. Similarly, the second connecting rod 142 and the second sliding sleeve can also be fixed together by a threaded connection, and the second protrusion on the outer ring of the second sliding sleeve is engaged in the second sliding groove 1246. This allows for relative sliding along the axial direction, and the rotation of the second connecting rod 142 can drive the rotation of the second sleeve 124.

[0048] like Figure 7 , Figure 8 and Figure 9 As shown, the pluggable controller assembly 100 also includes a micro switch 112 disposed on the base plate 110, and a pressure rod 1248 cooperating with the micro switch 112 is disposed on the second sleeve 124. When the second sleeve 124 is disengaged from the base plate 110, the pressure rod 1248 closes the micro switch 112. The micro switch 112 is used to connect with the trip unit to control the trip unit's operation.

[0049] Specifically, a pressure rod 1248 is provided on the second sleeve 124. When the second sleeve 124 rotates, the pressure rod 1248 rotates synchronously with the second sleeve 124, so that the pressure rod 1248 moves closer to or away from the micro switch 112. When the pressure rod 1248 approaches the micro switch 112, it contacts the contact of the micro switch 112 and drives the contact to move, thereby closing the micro switch 112. When it is necessary to release the locking relationship between the housing 120 and the base plate 110 and control the rotation of the second sleeve 124, the second sleeve 124 closes the micro switch 112 through the pressure rod 1248, thereby achieving overall circuit breaking through the trip unit, ensuring that the controller body is not energized during the removal process, which helps to improve the safety of operation.

[0050] like Figure 10As shown, the locking assembly 150 includes a locking body 152 connected to the housing 120, and a guide post elastically and slidably connected to the locking body 152. The guide post is provided with a first claw 154 and a second claw 156. The first latch 136 and the second latch 146 respectively cooperate with the guide post so that the first claw 154 and the second claw 156 move closer or further away from each other.

[0051] This embodiment uses the first operating member 130 as an example for explanation. The cooperation between the second operating member 140 and the locking assembly 150 is the same as that of the first operating member 130. When the first operating member 130 is pushed close to the locking assembly 150, the first latch 136 on the first operating member 130 contacts the guide post and pushes the guide post back into the locking body 152. When the guide post is retracted into the locking body 152, the first pawl 154 and the second pawl 156 provided on the guide post move into the locking body 152. The first pawl 154 and the second pawl 156 are respectively hinged or elastically connected to the guide post. When the first pawl 154 and the second pawl 156 move into the locking body 152, they move closer to each other, thereby locking the first latch 136. To unlock, simply press the first handle 134 again. The guide post, under the action of the elastic element within the locking body 152, moves outward from the locking body 152, causing the first latch 154 and the second latch 156 to move away from each other, thus releasing the lock on the first latch 136 (i.e., using the latching ball as the locking component 150 in this embodiment). With this configuration, locking is achieved by pressing the first handle 134, and unlocking is achieved by pressing it again, simplifying the operation and improving convenience.

[0052] like Figure 5 and Figure 11 As shown, the housing 120 is provided with a first slot 126 and a second slot 128 respectively. The first slot 126 corresponds to the first handle 134 so that the first handle 134 is embedded in the first slot 126; the second slot 128 corresponds to the second handle 144 so that the second handle 144 is embedded in the second slot 128.

[0053] Specifically, through the first slot 126 provided on the housing 120, the first handle 134 can only be pushed into the first slot 126 when its orthographic projection coincides with that of the first handle 134, and the first operating member 130 is locked by the locking component 150. To unlock, the first handle 134 is pressed again to release the lock and eject it from the first slot 126, facilitating the rotation of the first operating member 130. Similarly, through the second slot 128 provided on the housing 120, the second handle 144 can only be pushed into the second slot 128 when its orthographic projection coincides with that of the second handle 144, and the second operating member 140 is locked by the locking component 150. To unlock, the second handle 144 is pressed again to release the lock and eject it from the second slot 128, facilitating the rotation of the second operating member 140.

[0054] In an optional embodiment of this application, a first spring 1322 is sleeved on the first connecting rod 132, and the two ends of the first spring 1322 are respectively connected to the housing 120 and the first connecting rod 132, so that the first connecting rod 132 has an elastic force to detach from the housing 120; a second spring is sleeved on the second connecting rod 142, and the two ends of the second spring are respectively connected to the housing 120 and the second connecting rod 142, so that the second connecting rod 142 has an elastic force to detach from the housing 120.

[0055] Specifically, such as Figure 4 As shown, by connecting the two ends of the first spring 1322 to the housing 120 and the first connecting rod 132 respectively, when the first handle 134 is pressed and the locking assembly 150 locks the first operating member 130, the first spring 1322 is compressed and accumulates elastic potential energy. After the locking assembly 150 unlocks the first operating member 130, when the first elastic element recovers its elastic deformation, it causes the first handle 134 to pop out, avoiding the difficulty of the first operating member 130 popping out due to its tightness against the elastic element inside the locking assembly 150, which helps improve the reliability during use. Similarly, by connecting the two ends of the second spring to the housing 120 and the second connecting rod 142 respectively, when the second handle 144 is pressed and the locking assembly 150 locks the second operating member 140, the second spring is compressed and accumulates elastic potential energy. After the locking assembly 150 unlocks the second operating member 140, when the second elastic element recovers its elastic deformation, it causes the second handle 144 to pop out, avoiding the difficulty of the second operating member 140 popping out due to its tightness against the elastic element inside the locking assembly 150, which helps improve the reliability during use.
