Description

Technical Field

[0001] This application relates to the technical field of circuit breakers, and in particular to a protective structure and its circuit breaker faceplate. Background Technology

[0002] A circuit breaker is a power system protection device. Its function is to ensure that the power supply can be quickly cut off when abnormal conditions such as overload, short circuit or undervoltage occur, thereby protecting the safe and stable operation of electrical equipment and systems.

[0003] The related technical circuit breaker includes a circuit breaker base and a circuit breaker faceplate. A button for triggering the main circuit breaker switch is provided on the circuit breaker faceplate.

[0004] If a worker accidentally touches a button on the circuit breaker cover, the circuit breaker may be energized or de-energized, causing unexpected power outages or restorations to the equipment connected to the circuit breaker, affecting production or even causing safety accidents. Summary of the Invention

[0005] To address the issue of accidental button activation on circuit breaker covers, this application provides a protective structure and a circuit breaker cover thereof.

[0006] The protective structure provided in this application adopts the following technical solution:

[0007] A protective structure includes a mounting strip for mounting on a housing, a protective cover for covering a button on the housing being rotatably connected to the mounting strip, the protective cover having a receiving groove into which the mounting strip can rotate, and a locking component connecting the mounting strip and the protective cover.

[0008] By adopting the above technical solution, the mounting strip is installed on the circuit breaker cover, so that the protective cover will block the button on the circuit breaker cover. This prevents the operator from pressing the button on the circuit breaker cover, avoids accidental button activation, and reduces the probability of safety accidents. The connection between the mounting strip and the protective cover is released by the locking component, and then the protective cover is driven to rotate, so that the protective cover no longer blocks the button, and the operator can press the mounting strip.

[0009] Optionally, the upper inner wall of the receiving groove is provided with a first fixing hole for inserting the mounting strip. The bottom wall of the receiving groove is integrally formed with two fixing blocks. The mounting strip is located between the two fixing blocks. A fixing rod is integrally formed between the two fixing blocks. The end face of the mounting strip away from the bottom wall of the receiving groove is provided with a fixing groove for inserting the fixing rod. The locking assembly includes a locking rod disposed on the bottom wall of the receiving groove and a first locking block disposed on the side away from the fixing rod. The locking rod is deformable. A second locking block is disposed on the end face of the locking rod facing the first locking block. The first locking block and the second locking block can be engaged.

[0010] By adopting the above technical solution, when it is necessary to lock the protective cover and the mounting strip, the protective cover is first driven to rotate, so that the first locking block and the second locking block abut against each other, and the locking rod is driven to deform in a direction away from the mounting strip, so that the first locking block can move between the second locking block and the bottom wall of the receiving groove, so that the first locking block and the second locking block are engaged; conversely, the locking rod is driven to deform in a direction away from the mounting strip, and the protective cover is driven to rotate in the opposite direction to open the protective cover; the fixing rod is integrally formed on the protective cover, and the fixing rod can be inserted into the fixing groove, so that the protective structure does not need to set additional pins to connect the protective cover and the mounting strip, reducing the number of parts of the protective structure and reducing the number of assembly steps of the protective structure, which has the advantages of reducing the cost of the protective structure and improving the assembly efficiency of the protective structure.

[0011] Optionally, an arc-shaped strip is provided on the end face of the locking rod away from the second locking block. The connection point between the arc-shaped strip and the second locking block is located on the side of the locking rod away from the receiving groove. The arc-shaped strip extends towards the bottom wall of the receiving groove. An operating block is provided on the side of the arc-shaped strip away from the locking rod.

[0012] By adopting the above technical solution, a force is applied to the operating block, causing the locking rod to deform away from the mounting strip, so that the first locking block and the second locking block are no longer locked together, and the operator can rotate and open the protective cover.

[0013] Optionally, at least two snap-fit ​​components are provided on the side of the mounting strip away from the bottom wall of the receiving groove. The snap-fit ​​components include two locking rods provided on the side of the mounting strip away from the bottom wall of the receiving groove. The locking rods are deformable, and a first locking block is provided on the side of the two locking rods away from the bottom wall.

[0014] By adopting the above technical solution, during the process of installing the protective structure into the shell, the two locking rods are first deformed relative to each other, and then the first locking block and the locking rod are inserted into the first locking hole on the shell. When the first locking block passes through the first locking hole of the shell, the locking rod resets and drives the first locking block to move, thereby realizing the connection between the protective structure and the shell and achieving the effect of rapid installation of the protective structure.

[0015] Optionally, the mounting strip is provided with an arched block on the side facing the bottom wall of the receiving groove. The arched block can pass through the protective cover and extend outside the protective cover. The arched block is provided with a locking hole.

[0016] By adopting the above technical solution, after the protective cover covers the installation strip, the arched block extends out of the protective cover. The user can pass the hook of the padlock through the lock hole and install the padlock on the arched block, so that the protective cover is not easy to rotate relative to the installation strip, preventing unauthorized personnel from accidentally or misoperating the main switch.

[0017] A circuit breaker cover includes an outer shell, the outer shell including a housing and a cover, the cover being detachably connected to the outer surface of the housing, an installation structure connecting the housing and the cover being provided between the two, a button being provided on the side of the cover away from the housing, a protective structure being provided on the side of the cover away from the housing, and a first locking hole being provided on the cover for a locking rod and a first locking block to pass through.

[0018] By adopting the above technical solution, the protective cover in the drive protection structure rotates, and the protective cover no longer obstructs the button, allowing the operator to operate the button; conversely, the protective cover covers the button, preventing the operator from directly contacting the button and improving the safety of the circuit breaker; when the button is damaged, the cover and the housing can be separated, and the button on the cover can be removed and replaced, or the combination of the cover and the button can be replaced, without having to replace the entire circuit breaker faceplate, which can reduce maintenance costs.

[0019] Optionally, the end face of the cover facing the housing has a storage groove, the bottom wall of the storage groove has a mounting cylinder, the end face of the mounting cylinder facing the bottom wall of the storage groove has a mounting groove, the end face of the cover away from the housing has a mounting hole communicating with the mounting groove, the button is disposed in the mounting groove, the end face of the button facing the bottom wall of the mounting groove has a push rod, the bottom wall of the mounting groove has a punch hole for inserting the push rod; the end face of the button facing the bottom wall of the mounting groove has two insert rods, the end faces of the two insert rods away from each other have insert blocks, the inner wall of the mounting groove has a first insertion hole, and the insert block is slidably disposed in the first insertion hole.

[0020] By adopting the above technical solution, when the plug rod is deformed, the plug block and the plug rod are inserted into the mounting groove together. When the plug block is aligned with the first socket, the plug rod is reset so that the plug block is inserted into the first socket, and the button is connected to the cover. The button is driven to move along the axis of the mounting groove so that the push rod on the button can trigger the switch inside the circuit breaker.

[0021] Optionally, the mounting structure includes two mounting rods disposed on the side of the cover facing the housing. The mounting rods are deformable, and each of the two mounting rods has a mounting block on its opposite end face. The housing has a locking hole on its end face facing the cover, through which the mounting rods and mounting blocks can pass. The mounting block abuts against the inner wall of the housing near the cover.

[0022] By adopting the above technical solution, the mounting rod is driven to deform, so that the mounting rod and the mounting block pass through the locking hole. After the mounting block passes through the locking hole, the mounting rod resets and drives the mounting block to move. The mounting block abuts against the inner wall of the housing near the cover, so that the cover and the housing are locked together, thus realizing the rapid installation of the cover and the housing.

[0023] Optionally, a second locking block is provided on the end face of the locking rod away from the axis of the first locking hole. The second locking block is located on the side of the first locking hole away from the mounting strip. A locking member is provided on the housing. A receiving groove is provided on the end face of the housing away from the cover. A second locking hole is provided on the housing to allow the second locking block and the locking rod to pass through. The second locking hole fits against the bottom wall of the receiving groove. A locking member is provided on the housing to restrict the locking rod from disengaging from the second locking hole. Locking ring grooves are provided on the end faces of the two second locking blocks away from the locking rod. The locking member includes a first retaining spring. The first retaining spring is engaged in the locking ring groove. A locking block is provided on the inner wall of the first retaining spring and inserted between the two locking rods. The end faces of the two locking rods that are close to each other abut against the locking block.

[0024] By adopting the above technical solution, the connection between the shell, cover and protective structure is made more secure through the second locking block and locking rod; the first locking spring is installed on the locking rod, so that the locking part is inserted between the two locking rods, making it difficult for the two locking rods to deform in the axial direction of the second locking hole, and preventing the locking rods from coming out of the second locking hole.

[0025] Optionally, a second locking block is provided on the end face of the locking rod away from the axis of the first locking hole. The second locking block is located on the side of the first locking hole away from the mounting strip. A locking member is provided on the housing. A receiving groove is provided on the end face of the housing away from the cover. A second locking hole is provided on the housing to allow the second locking block and the locking rod to pass through. A locking member is provided on the housing to prevent the locking rod from disengaging from the second locking hole. The locking member includes a second retaining spring and two elastic strips provided on the bottom wall of the receiving groove. The two locking rods are located between the two elastic strips. The end face of the elastic strip away from the bottom wall of the receiving groove is in contact with the second locking block. The end faces of the two elastic strips away from each other are provided with locking grooves. The second locking spring is locked in the locking groove. The inner wall of the second locking spring is provided with a locking shaft that is inserted between the two locking rods. The locking rod is provided with a guide angle. The guide angle is located at the junction of the end face of the locking block away from the axis of the second locking block and the side of the locking rod away from the mounting strip. When the locking rod abuts against the locking shaft, the elastic strip is on the path of the second locking block moving along the axis of the second locking hole.

[0026] By adopting the above technical solution, the connection between the shell, cover, and protective structure is made more secure through the second locking block and locking rod; during the movement of the locking rod, its reset allows the two elastic strips to deform.

[0027] The contact between the guide shaft and the guide ramp causes the two elastic strips to deform as the locking rods move, until the gap between the two locking rods allows the locking shaft to pass through. When the second locking block moves to the side of the elastic strip away from the receiving groove, the locking rods return to their initial state, causing the second locking block to fit against the side of the elastic strip away from the bottom wall of the receiving groove, thus connecting the second locking block to the housing. Using the above installation method, workers can open the second retaining spring without the aid of tools, reducing the assembly steps of the circuit breaker cover and improving the production efficiency of the circuit breaker cover.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Install the mounting strip onto the circuit breaker faceplate so that the protective cover blocks the buttons on the circuit breaker faceplate, preventing operators from pressing the buttons on the circuit breaker faceplate, thus avoiding accidental button activation and reducing the probability of safety accidents; release the connection between the mounting strip and the protective cover by locking the component, and then drive the protective cover to rotate so that the protective cover no longer blocks the buttons, allowing operators to press the mounting strip.

[0030] 2. Connect the cover and the shell using mounting rods and mounting blocks to achieve quick installation of the cover and the shell. Attached Figure Description

[0052] Reference Figure 3 and Figure 4Each of the two mounting slots 43 is equipped with a button 6, and the side of the button 6 away from the bottom wall of the mounting slot 43 is inserted into the mounting hole 44. A push rod 61 is fixedly connected to the end face of the button 6 facing the bottom wall of the mounting slot 43. A punch hole 45 is provided on the bottom wall of the mounting slot 43, through which the push rod 61 can pass.

[0053] Reference Figure 3 One button 6 is used to trigger the main switch for starting the circuit breaker, and the other button 6 is used to trigger the main switch for closing the circuit breaker. The two buttons 6 can be made of different colored materials. Each of the two buttons 6 has an identification groove on its end face away from the push rod 61, and the two identification grooves have different shapes.

[0054] Reference Figure 3 and Figure 4 Button 6 is fixedly connected to two insert rods 62 facing the bottom wall of mounting groove 43. The distance between the end face of insert rod 62 away from the bottom wall of storage groove 41 and the bottom wall of storage groove 41 is less than the distance between the end face of mounting cylinder 42 away from the bottom wall of storage groove 41 and the bottom wall of storage groove 41.

[0055] Reference Figure 3 and Figure 4 A plug 63 is fixedly connected to the plug rod 62 away from the axis of the mounting groove 43.

A fixing groove 211 is formed on the end face of the mounting strip 21 facing the cover 4, and the fixing groove 211 is located above the snap-fit ​​assembly 24. The fixing groove 211 extends through the mounting strip 21 along the distribution direction of the buttons 6. The fixing rod 225 can be inserted into the fixing groove 211. The protective cover 22 can rotate about the axis of the fixing rod 225.

[0063] Reference Figure 5 and Figure 6 The locking assembly 23 is used to connect the mounting strip 21 to the protective cover 22. The locking assembly 23 includes a first locking block 231, a locking lever 232, a second locking block 233, an arc-shaped strip 234, and an operating block 235.

[0064] Reference Figure 5 and Figure 6 The first locking block 231 is fixedly connected to the lower end face of the mounting strip 21. The first locking block 231 has a first chamfer, which is located at the junction of the end face of the first locking block 231 away from the cover 4 and the lower end face of the first locking block 231.

The second locking block 233 is fixedly connected to the end face of the locking rod 232 facing the first locking block 231. The second locking block 233 has a second chamfer, which is located at the junction of the end face of the second locking block 233 facing the cover 4 and the upper end face of the second locking block 233. The second locking block 233 can engage with the first locking block 231.

[0066] Reference Figure 5 and Figure 6 The arc-shaped strip 234 is fixedly connected to the end face of the locking rod 232 away from the second locking block 233, and the connection point between the arc-shaped strip 234 and the locking rod 232 is located on the side of the locking rod 232 away from the bottom wall of the receiving groove 221. The arc-shaped strip 234 extends towards the bottom wall of the receiving groove 221. The operating block 235 is fixedly connected to the side of the arc-shaped strip 234 away from the locking rod 232.

[0067] Reference Figure 5 and Figure 6 When the first locking block 231 and the second locking block 233 are engaged, the driving operation block 235 moves away from the cover 4, causing the operation block 235 to drive the locking rod 232 to deform away from the first locking block 231 through the arc strip 234, so that the first locking block 231 is no longer engaged with the second locking block 233, and the user can rotate the protective cover 22 to open. At this time, the user can press the button 6.

[0068] Reference Figure 3 and Figure 5 An arched block 212 is fixedly connected to the end face of the mounting strip 21 away from the locking rod 241. The end face of the arched block 212 away from the mounting strip 21 is set as an arc surface. A locking hole 2121 is opened on the end face of the arched block 212 along the axis of the fixing rod 225. A through hole 226 is opened on the end face of the protective cover 22 away from the cover body 4, and the through hole 226 allows the arched block 212 to pass through.

[0069] Reference Figure 3 and Figure 5 When the first locking block 231 and the second locking block 233 are engaged, the end of the arched block 212 away from the mounting strip 21 passes through the perforation 226 and extends out of the protective cover 22. At this time, part of the perforation 226 is located outside the protective cover 22, and the user can install a padlock on the arched block 212.

[0070] The implementation principle of Example 1 is as follows: When button 6 is needed, a force is first applied to the operating block 235, causing the operating block 235 to deform the locking rod 232 through the arc strip 234, so that the first locking block 231 is no longer engaged with the second locking block 233, and then the protective cover 22 is driven to rotate, so that the protective cover 22 no longer blocks the button 6, and the operator presses the button 6 to open and close the circuit breaker.

The first locking spring 71 is disposed in the locking ring groove 2431.

[0075] Reference Figure 7 and Figure 8A stop block 72 is fixedly connected to the end face of the first retaining spring 71 away from the second retaining block 243. The end face of the stop block 72 away from the first retaining spring 71 is in contact with the bottom wall of the receiving groove.

[0076] Reference Figure 7 and Figure 8 The locking block 73 is fixedly connected to the inner wall of the first retaining spring 71. The locking block 73 can be inserted between the two retaining rods 241. The upper end face of the locking block 73 abuts against one retaining rod 241, and the lower end face of the locking block 73 abuts against the other retaining rod 241. The locking block 73 restricts the deformation of the two retaining rods 241 in the axial direction of the second retaining hole 37. When the retaining rod 241 abuts against the locking block 73, the inner wall of the receiving groove is still on the path of the second retaining block 243 moving along the axial direction of the second retaining hole 37.

[0077] The implementation principle of Embodiment 2 is as follows: The locking rod 241 deforms, allowing the second locking hole 37 and the locking rod 241 to pass through the second locking hole 37 together. The locking rod 241 resets, driving the second locking block 243 to move, so that the second locking block 243 fits against the bottom wall of the receiving groove. Then, the first retaining spring 71 is driven to open and is inserted into the locking ring groove 2431, realizing the connection between the mounting strip 21 and the housing 3.

[0078] Example 3

[0079] Reference Figure 9 and Figure 10 The difference between this embodiment and embodiment 2 is that the locking component 7 includes an elastic strip 74, a second retaining spring 75, and a locking shaft 76.

[0080] Reference Figure 9 and Figure 10 Two elastic strips 74 are provided, and both elastic strips 74 are fixedly connected to the bottom wall of the receiving groove. The two elastic strips 74 are located between the two locking rods 241. The end faces of the two elastic strips 74 that are far from each other have locking grooves 741. The second locking block 243 is in contact with the end face of the elastic strip 74 that is far from the bottom wall of the receiving groove.

[0081] Reference Figure 9 and Figure 10 The second retaining ring 75 is disposed within the two retaining slots 741. The maximum distance between the two positioning blocks along the radial direction of the second retaining hole 37 is greater than the inner diameter of the second retaining ring 75, making it difficult for the second retaining ring 75 to detach from the two elastic strips 74.

[0082] Reference Figure 9 and Figure 10The locking shaft 76 is fixedly connected to the inner wall of the second retaining spring 75, and the locking shaft 76 can be inserted between the two retaining rods 241. The locking shaft 76 restricts the deformation of the two retaining rods 241 in the axial direction of the second retaining hole 37. When the retaining rods 241 abut against the locking shaft 76, the elastic strip 74 is still on the path of the second retaining block 243 moving along the axial direction of the second retaining hole 37.

[0083] Reference Figure 9 and Figure 10 The end face of the locking rod 241 away from the mounting strip 21 is provided with a guide chamfer. The guide chamfer is located at the junction of the end face of the locking rod 241 facing the locking shaft 76 and the side of the locking rod 241 away from the mounting strip 21.

[0084] The implementation principle of Example 3 is as follows: The clamping rod 241 is deformed, causing the second clamping hole 37 and the clamping rod 241 to pass through the second clamping hole 37 together. The clamping rod 241 then resets, causing the second clamping block 243 to move until it is in contact with the end face of the elastic strip 74 facing the second clamping hole 37. The clamping rod 241 continues to reset, and the second clamping block 243 causes the elastic strip 74 to deform away from the second clamping hole 37. This drives the mounting strip 21 to continue moving towards the cover 4, causing the guide chamfer to abut against the locking shaft 76. As the clamping rod 241 continues to move, the two elastic strips 74 move away from each other, allowing the locking shaft 76 to smoothly move between the two clamping rods 241, causing the second clamping block 243 to fit against the bottom wall of the receiving groove, thus achieving the connection between the mounting strip 21 and the housing 3.
