Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to a locking mechanism, a plug-in box, and a power distribution system. Background Technology

[0002] A plug-in box is a device that connects electrical equipment to a busbar trunking system. It connects to the busbar trunking system via a plug, making close contact with the conductive plate inside the busbar trunking system to supply power to the electrical equipment.

[0003] To ensure a secure connection, existing technologies typically incorporate a locking mechanism on the connector box. During installation, the locking mechanism reliably locks the connector box onto the busbar; during disassembly, the locking mechanism must be unlocked before the connector box can be removed.

[0004] However, during routine maintenance and installation of the connector box, there is a risk that the unlocking mechanism on the connector box may be accidentally triggered. Such misoperation may cause the connector box to fall off unexpectedly, posing a safety hazard. Utility Model Content

[0005] The main purpose of this application is to propose a locking mechanism, a plug-in box, and a power distribution system, which aims to solve the problem that the locking mechanism of the existing plug-in box is easily unlocked by accident, posing a safety hazard.

[0006] To achieve the above objectives, the locking mechanism proposed in this application includes an operating mechanism and a locking component. The operating mechanism includes a support component, a button, and a linkage mechanism. The button is configured to trigger the linkage mechanism to unlock and lock. The button has at least one groove.

[0007] The locking member is movably mounted on the support member, and the locking member has a locking foot on the side facing the button. The locking member is configured such that when the locking foot abuts against the groove, the button and the linkage mechanism are in a restricted movement state; when the locking member moves away from the button, the locking member drives the locking foot to disengage from the groove, so that the button is in a movable state.

[0008] In some embodiments, the locking member is rotatably mounted on the support member, and the locking member rotates relative to the button in a direction away from the button to disengage the locking foot from the groove.

[0009] In some embodiments, the button has at least two grooves on the side facing the locking member, including a first groove and a second groove. When the locking foot abuts against the first groove, both the button and the linkage mechanism are in a restricted movement state. When the locking foot abuts against and engages with the second groove, the linkage mechanism is in a locked state.

[0010] In some embodiments, when the locking member is rotated under force, the locking foot disengages from the first groove or the second groove; after the external force is released, the locking member rotates in the opposite direction, causing the locking foot to move to abut against the first groove or the second groove.

[0011] In some embodiments, the outer edge of the locking foot is provided with a stop structure, and the inner wall of the groove is provided with an abutment structure that complements the stop structure; when the locking foot is engaged in the groove, the stop structure abuts against the abutment structure to form an anti-disengagement structure, thereby positioning the locking foot in the groove.

[0012] In some embodiments, the locking member includes an elastic reset member configured such that, after the external force is released, the elastic reset member drives the locking member to reset, causing the locking foot to abut against the groove.

[0013] In some embodiments, the elastic reset member is a latch structure, and the support member has a support block protruding from the latch structure. One end of the latch structure is fixed to the locking member, and the other end extends to form an elastic arm that abuts against the support block.

[0014] The latch structure is configured such that when an external force drives the locking member to rotate, the elastic arm of the latch structure is blocked by the support block and deforms; after the external force is released, the elastic arm of the latch structure drives the locking member to rotate and reset through elastic restoring force, so that the locking foot abuts against the groove.

[0015] In some embodiments, the support member includes a support member body and a handle, the handle being connected to one side of the support member body. The locking member has a limiting structure on the side facing the support member body, with a gap between the limiting structure and the support member body; when the locking member rotates to disengage the locking foot from the groove, the limiting structure rotates with the locking member and abuts against the corresponding side of the support member body to form a stop surface that restricts the rotation of the locking member.

[0016] In some embodiments, the button has at least two grooves on the side opposite to the locking member.

[0017] This application also proposes a plug-in box, which includes a locking mechanism.

[0018] This application also proposes a power distribution system comprising a busbar trunking and a plug-in box, wherein the plug-in box is locked to the trunking of the busbar trunking or is detached from the trunking of the busbar trunking.

[0019] The technical solution of this application employs a method of providing at least one groove on the button and a locking member on a support member. The locking member is movably mounted on the support member, and a locking foot is provided on the side of the locking member facing the button. The locking member is configured such that: when the locking foot engages with the groove, the button and the linkage mechanism are in a restricted movement state; when the locking member moves away from the button, it causes the locking foot to disengage from the groove, making the button movable. Because the button cannot be pushed when the locking foot of the locking member abuts against the groove of the button, the linkage mechanism is prevented from being unlocked, thus preventing accidental button activation that could trigger the unlocking of the linkage mechanism, thereby improving safety.

[0027] A plug-in box is a device that connects electrical equipment to a busbar trunking system. It connects to the busbar trunking system via a plug, making close contact with the conductive plate inside the busbar trunking system to supply power to the electrical equipment.

[0028] To ensure a secure connection, existing technologies typically incorporate a locking mechanism on the connector box. During installation, the locking mechanism reliably locks the connector box onto the busbar; during disassembly, the locking mechanism must be unlocked before the connector box can be removed.

[0029] However, during routine maintenance and installation of the connector box, there is a risk that the unlocking mechanism on the connector box may be accidentally triggered. Such misoperation may cause the connector box to fall off unexpectedly, posing a safety hazard.

[0030] This application discloses a locking mechanism 100. Please refer to... Figure 1 and Figure 2The locking mechanism 100 proposed in this application includes an operating mechanism 10 and a locking member 20. The operating mechanism 10 includes a support member 11, a button 12 and a linkage mechanism. The button 12 is configured to trigger the linkage mechanism to unlock and lock. The button 12 is provided with at least one groove 120.

[0031] The locking member 20 is movably mounted on the support member 11. The locking member 20 has a locking foot 21 on the side facing the button 12. The locking member 20 is configured such that when the locking foot 21 abuts against the groove 120, the button 12 and the linkage mechanism are in a state of restricted movement. When the locking member 20 moves away from the button 12, the locking member 20 drives the locking foot 21 to disengage from the groove 120, so that the button 12 is in a movable state.

[0032] The support member 11 is provided with a mounting groove, the linkage mechanism is located inside the mounting groove, and the button 12 is connected to the linkage mechanism in the mounting groove.

[0033] The side of the button 12 is provided with at least one groove 120, and the button 12 can be triggered by the user's pressing action to activate the linkage mechanism. Since the locking foot 21 of the locking member 20 abuts against the groove 120 of the button 12, the button 12 is locked when the locking member 20 is not operated by the user, and the button 12 is in a restricted movement state to reduce the possibility of accidental activation of the button 12.

[0034] Specifically, the locking member 20 is movably mounted on the support member 11, and the locking member 20 has a protruding locking foot 21 on the side facing the button 12. When the locking foot 21 is precisely inserted into the groove 120 of the button 12, the position of the button 12 is locked and fixed, so that the linkage mechanism is also in a state of restricted movement. When unlocking is required, the user operates the locking member 20 to move it away from the button 12, so as to drive the locking foot 21 out of the groove 120, thereby releasing the constraint on the button 12, so that the button 12 can be pressed and pushed, thus making it convenient for the user to push the button 12 to trigger the linkage mechanism to unlock.

[0035] Optionally, the locking member 20 can be translated on the support member 11 along a direction perpendicular to the pressing direction of the button 12, and the locking member 20 is equipped with a reset member. Normally, the locking foot 21 is locked in the groove 120, restricting the movement of the button 12. When unlocking is required, pulling or flicking the locking member 20 overcomes the spring force, causing the locking member 20 to translate, which in turn moves the locking foot 21 along a straight path perpendicular to the pressing direction of the button 12. The locking foot 21 disengages from the groove 120, and the button 12 becomes movable.

[0036] Optionally, the locking member 20 is hinged to the support member 11 to form a lever structure that can rotate around a fulcrum. One end of the locking member 20 is provided with a locking foot 21, and the other end serves as the operating end. When the user presses down on the operating end, the locking foot 21 is lifted, causing it to disengage from the groove 120. The locking member 20 is equipped with a reset member so that after the external force is released, the locking member 20, relying on the reset member or gravity, resets the locking foot 21 and locks it back into the groove 120, thereby constraining the button 12 and reducing the possibility of accidental activation of the button 12.

[0037] Optionally, the locking member 20 is provided with multiple locking feet 21, and correspondingly, the button 12 is provided with multiple grooves 120 or notches. The multiple locking feet 21 are respectively abutted against the multiple grooves 120 or notches to form multi-point locking, thereby improving the stability of locking.

[0038] Optionally, a magnet is provided between the support member 11 and the locking member 20. The locking member 20 can be a metal part. Through the magnetic attraction of the magnet to the locking member 20, under normal conditions, the magnet can attract the locking member 20 to the button 12, and the locking tab 21 on the locking member 20 is locked into the groove 120. When unlocking is required, an external force is applied to the locking member 20 to pull away from the button 12 to overcome the magnetic force, so that the locking tab 21 on the locking member 20 disengages from the groove 120, and the button 12 is in an unlocked movable state that can be pressed and pushed.

[0039] Optionally, the groove 120 on the button 12 can be configured as a semi-closed through-hole structure, so that the locking pin 21 can rotate and engage with the through-hole structure in normal operation. Under the action of external force, the locking pin 21 can rotate out of the through-hole structure, so that the button 12 is in an unlocked movable state that can be pressed and pushed.

[0040] The technical solution of this application employs at least one groove 120 on the button 12 and a locking member 20 on the support member 11. The locking member 20 is movably mounted on the support member 11, and a locking foot 21 is provided on the side of the locking member 20 facing the button 12. The locking member 20 is configured such that: when the locking foot 21 is engaged with the groove 120, the button 12 and the linkage mechanism are in a restricted movement state; when the locking member 20 moves away from the button 12, the locking member 20 causes the locking foot 21 to disengage from the groove 120, making the button 12 movable. Since the button 12 cannot be pushed when the locking foot 21 of the locking member 20 is engaged with the groove 120 of the button 12, the linkage mechanism is not unlocked, preventing accidental touch of the button 12 and triggering the unlocking of the linkage mechanism, thus improving safety.

[0041] To save effort when operating the locking member 20, the locking member 20 is rotatably mounted on the support member 11. The locking member 20 rotates relative to the button 12 in a direction away from the button 12 so that the locking foot 21 disengages from the groove 120.

[0042] When the locking foot 21 abuts against the groove 120, the displacement of the button 12 is constrained. When it is necessary to release the locked state of the button 12, an external force is applied to drive the locking member 20 to rotate around its mounting axis, causing the locking foot 21, which was originally abutting against the groove 120, to rotate and rise relative to the button 12 in a direction away from the button 12. Finally, the locking foot 21 completely disengages from the groove 120, the locked state of the button 12 is released, and the button 12 can be pushed, so that the button 12 can be pressed normally to trigger the linkage mechanism to unlock.

[0043] Once the user releases the external force applied to button 12, the locking member 20 can rotate in the opposite direction under the action of the reset member, thereby driving the locking foot 21 to reset and allowing the locking foot 21 to re-lock into the groove 120, thus constraining the displacement of button 12.

[0044] Since the locking component 20 is rotatably mounted on the support component 11, the locking component 20 has a lever effect on the support component 11. The user can drive the locking component 20 to rotate by applying a small force. Compared with the method of using a linear pull-out locking component 20, rotating and lifting the locking component 20 is more labor-saving.

[0045] Please see Figure 1 , Figure 3 and Figure 4 The button 12 has two sliding directions corresponding to the unlocking and locking linkage mechanisms, respectively. To keep the linkage mechanism in a switched state rather than an unlocked state, or to keep the linkage mechanism in a locked state, the side of the button 12 facing the locking member 20 has at least two grooves 120, including a first groove 121 and a second groove 122. When the locking foot 21 abuts against the first groove 121, the button 12 and the linkage mechanism are in a restricted movement state.

[0046] In one embodiment, when the locking foot 21 abuts against the first groove 121, the button 12 and the linkage mechanism are in a switching state, not an unlocked state. When the locking foot 21 abuts against the second groove 122, the button 12 is in a movable state. The user can rotate the locking member 20 to disengage the locking foot 21 from the first groove 121 or the second groove 122. Afterward, when the user slides the button 12 along its length, the button 12 drives the linkage mechanism to unlock or lock. After the external force on the locking member 20 is released, the locking member 20 rotates in the opposite direction, causing the locking foot 21 to move to abut against the first groove 121 or the second groove 122.

[0047] Specifically, one side of the first groove 121 of button 12 is the unlock position, and the other side is the lock position. The first groove 121 can be a mounting position located between the unlock position and the lock position. When the locking foot 21 abuts against the first groove 121, the displacement of button 12 is constrained, causing button 12 and the linkage mechanism to switch between an unlocked state and a locked state. When the locking member 20 is not activated by the user, button 12 cannot be triggered, thereby preventing accidental activation of button 12 and triggering the linkage mechanism to unlock, thus improving safety.

[0048] The two directions in which the button 12 slides on the support 11 correspond to the unlocking direction and the locking direction of the linkage mechanism, respectively.

[0049] When it is necessary to release the locked state of button 12, an external force is applied to drive the locking member 20 to rotate around its mounting axis. This causes the locking foot 21, which was originally abutting in the first groove 121, to rotate and rise relative to button 12 in a direction away from button 12. Eventually, the locking foot 21 completely disengages from the first groove 121, releasing the restricted movement of button 12. Button 12 can then be pushed, allowing it to be pressed normally, so that the user can trigger the linkage mechanism to unlock by pushing button 12. Afterward, the user can push button 12 in the direction that drives the linkage mechanism to unlock, thereby unlocking the linkage mechanism. Alternatively, the user can push button 12 in the direction that drives the linkage mechanism to lock, thereby locking the linkage mechanism.

[0050] If the linkage mechanism is pushed and locked, in order to ensure that the linkage mechanism can remain in the locked state, the user can release the external force applied to the locking member 20. The locking member 20 can rotate in the opposite direction under the action of the reset member, so as to drive the locking foot 21 to reset and make the locking foot 21 re-lock into the second groove 122, thereby making the button 12 locked by the locking member 20 again. The linkage mechanism can remain in the locked state for a long time, effectively preventing the button 12 from moving in the direction that drives the linkage mechanism to unlock.

[0051] In one embodiment, please refer to Figure 3 and Figure 4 The first groove 121 on button 12 can be used as the mounting position, and the second groove 122 on button 12 is used as the locking position. The locking foot 21 on the locking member 20 is locked in the first groove 121, and button 12 is locked. At this time, the linkage mechanism is in a switching state between the unlocked state and the locked state, and the hook on the linkage mechanism is in a switching state. In this state, the user can install multiple parts of the linkage mechanism to complete the installation of the locking mechanism 100.

[0052] The locking foot 21 on the locking component 20 is locked in the second groove 122, and the button 12 and the linkage mechanism are in a locked state. At this time, if the locking component 20 is not subjected to external force by the user, the button 12 is not easily accidentally operated.

[0053] When the user moves the locking piece 20 away from the button 12, and the locking foot 21 is completely disengaged from the first groove 121, the button 12 is in a movable state. The user can slide the button 12 towards the linkage mechanism to lock the linkage mechanism; the user can also slide the button 12 away from the linkage mechanism to unlock the linkage mechanism.

[0054] This application uses the cooperation between the locking foot 21 and the groove 120 to keep the button 12 in a restricted movement state, so that the linkage mechanism is not easily unlocked by accidental touch.

[0055] Please see Figure 2 , Figure 5 and Figure 6 To reduce the possibility of the locking foot 21 detaching from the groove 120 due to vibration or accidental touch, thus preventing the button 12 from being unrestricted, a stop structure 210 is provided on the outer edge of the locking foot 21, and an abutment structure 1220 complementary to the stop structure 210 is provided on the inner wall of the groove 120. When the locking foot 21 is engaged in the groove 120, the stop structure 210 abuts against the abutment structure 1220 to form an anti-detachment structure, thus positioning the locking foot 21 in the groove 120. The abutment structure 1220 can be provided on the inner wall of both the first groove 121 and the second groove 122. Optionally, the stop structure 210 can be configured as a wedge-shaped protrusion, a spherical protrusion, or a hook-shaped protrusion, etc.

[0056] Specifically, the inner wall of the groove 120 is provided with complementary abutment structures 1220. The abutment structure 1220 can be configured as a slope that matches the wedge-shaped protrusion, an arc-shaped recess that matches the spherical protrusion, a slot that matches the hook-shaped protrusion, etc.

[0057] When the locking member 20 rotates under external force, the locking foot 21 disengages from the first groove 121. The user pushes the button 12 to slide in the direction of locking the linkage mechanism, thus locking the linkage mechanism. Afterward, the external force on the locking member 20 is released, causing the locking foot 21 to engage with the second groove 122. At this time, the stop structure 210 and the abutment structure 1220 come into contact with each other to form an interlocking anti-disengagement structure. This not only restricts the displacement of the locking foot 21 along the sliding direction of the button 12, but also constrains the locking foot 21 to disengage in a direction perpendicular to the contact surface. This ensures that the locking foot 21 is firmly constrained in the second groove 122 and cannot disengage due to vibration or accidental touch, thus ensuring that the button 12 is constrained by the locking member 20 in the locked position of the linkage mechanism for a long time, and the linkage mechanism can remain locked for a long time.

[0058] Please see Figure 4, Figure 5 and Figure 6 The inner wall of the first groove 121 facing away from the stop structure 210 is set as a baffle wall to abut against the side of the locking foot 21, so as to ensure that the locking foot 21 is not easily detached from the first groove 121.

[0059] To ensure that the locking pin 21 on the locking member 20 remains in contact with the groove 120 for an extended period when not in use by the user, please refer to [link to relevant documentation]. Figure 2 and Figure 4 The locking member 20 includes an elastic reset member 23, which is configured such that after the external force is released, the elastic reset member 23 drives the locking member 20 to reset, so that the locking foot 21 abuts against the groove 120.

[0060] When the user moves the locking member 20 and causes the locking foot 21 to disengage from the groove 120, the elastic reset member 23 deforms synchronously to store mechanical energy. Once the user releases the locking member 20, the mechanical energy stored in the elastic reset member 23 is immediately converted into elastic restoring force and drives the locking member 20 to move in the opposite direction until the locking foot 21 on the locking member 20 re-abuts against the first groove 121 or the second groove 122. This ensures that the locking foot 21 always abuts against the first groove 121 or the second groove 122 when not in operation, eliminating the risk of the locking foot 21 disengaging from the groove 120 due to vibration or accidental contact, and preventing the linkage mechanism from unlocking on its own.

[0061] Optionally, the elastic reset member 23 can be a spring, with one end of the spring fixed to the support member 11 or the housing, and the other end connected to the locking member 20.

[0062] Optionally, the elastic reset member 23 can be a torsion spring, which is sleeved on the rotating shaft of the locking member 20. One end of the torsion spring is fixed to the support member 11, and the other end is locked to the arm of the locking member 20. When the locking member 20 rotates, the torsion spring undergoes torsional deformation. When resetting, it releases torque to drive the locking member 20 to rotate.

[0063] Optionally, the elastic reset member 23 can be a spring sheet structure. The locking member 20 is provided with a spring sheet structure. When the locking member 20 is driven by an external force, the spring sheet structure on the locking member 20 bends and deforms. After the locking member 20 is released, the spring sheet structure rebounds and drives the locking foot 21 on the locking member 20 to re-engage in the groove 120.

[0064] To drive the locking member 20 to reset and rotate, and to provide the locking member 20 with a point of force for self-reset, please refer to... Figure 2 , Figure 4 and Figure 6The elastic reset member 23 is a latch structure. The support member 11 has a support block 110 protruding from the latch structure. One end of the latch structure is fixed to the locking member 20, and the other end extends to form a spring arm 230 that abuts against the support block 110. The latch structure is configured such that when an external force drives the locking member 20 to rotate, the spring arm 230 of the latch structure is blocked by the support block 110 and deforms; after the external force is released, the spring arm 230 of the latch structure drives the locking member 20 to rotate and reset through the elastic restoring force, so that the locking foot 21 abuts against the groove 120.

[0065] The latch structure is directly integrated into the locking component 20. One end of the latch structure can be fixed to the body of the locking component 20 by welding, riveting, etc., while the other end of the latch structure extends into a cantilevered spring arm 230.

[0066] Correspondingly, the support member 11 is provided with a support block 110 protruding from the position of the movement trajectory of the spring arm 230.

[0067] When the user applies external force to drive the locking component 20 to rotate, the spring arm 230 moves with the locking component 20 until it contacts and is blocked by the support block 110. At this time, the spring arm 230 is forced to undergo elastic bending deformation, converting the user's kinetic energy into the elastic potential energy of the material and storing it. Once the user releases the external force, the spring arm 230 immediately releases the stored elastic potential energy, and the latch structure pushes the locking component 20 to rotate in the opposite direction through its own restoring force until the locking foot 21 abuts against the first groove 121 or the second groove 122 again.

[0068] In one embodiment, the locking member 20 is hollowed out, the locking structure is set in the hollowed-out space, and one end of the tongue structure is connected to the locking member 20, while the other end of the tongue structure extends into a cantilevered spring arm 230 in the hollowed-out space.

[0069] To avoid overtravel of the locking element 20, please refer to [link / reference needed]. Figure 2 and Figure 4 The support member 11 includes a support member body 111 and a handle 112, with the handle 112 connected to one side of the support member body 111. The locking member 20 has a limiting structure 24 on the side facing the support member body 111, with a gap between the limiting structure 24 and the support member body 111; when the locking member 20 rotates to disengage the locking foot 21 from the groove 120, the limiting structure 24 rotates with the locking member 20 and abuts against the corresponding side of the support member body 111.

[0070] The support body 111 and handle 112 can be connected by threaded connection, snap-fit ​​connection, or other methods. The handle 112 is equipped with a locking element 20, a button 12, and a linkage mechanism. The locking element 20 has a protruding limiting structure 24 on its side facing the support body 111, with a pre-existing gap between the limiting structure 24 and the support body 111. When the user drives the locking element 20 to rotate, causing the locking foot 21 to disengage from the groove 120, the limiting structure 24 rotates synchronously with the locking element 20 until it abuts against the corresponding side wall of the support body 111, forming a stop surface that restricts the rotation of the locking element 20. At this time, the rotation angle of the locking element 20 is constrained, effectively preventing forced manipulation of the locking element 20.

[0071] Optionally, the limiting structure 24 can be configured as a wedge block, an arc baffle, etc.

[0072] Further, please refer to Figure 2 , Figure 4 and Figure 6 The locking component 20 is also equipped with a toggle block 22 for the user to lift and move. The toggle block 22 protrudes relative to the support component 11 and has a pressure groove 220 that matches the thumb. When the user operates the locking component 20, the user can press the pressure groove 220 of the toggle block 22 with their thumb and push the toggle block 22 upward a certain distance, causing the locking feet 21 on the locking component 20 to disengage from the groove 120 on the button 12. Afterward, the user can slide the button 12 left or right to drive the linkage mechanism to unlock and lock.

[0073] To improve the installation adaptability of the locking mechanism 100 on the support member 11, the button 12 is provided with at least two grooves 120 on the side away from the locking member 20. The two grooves 120 on the side of the button 12 away from the locking member 20 are mirror-symmetrical to the first groove 121 and the second groove 122 on the side of the button 12 facing the locking member 20 on both sides of the button 12.

[0074] When the locking mechanism 100 needs to be installed on the support member 11, the user can rotate the button 12 180° to choose the direction of installation according to the actual situation, so that the button 12 can be installed on the front or rear side of the support member 11 without modifying the structure of the support member 11 or adding adapter parts.

[0075] In one embodiment, the front and rear sides of the locking member 20 are provided with a toggle block 22 so that the user can toggle the locking member 20 on the front or rear side, thereby raising the locking foot 21 on the locking member 20.

[0076] This application also proposes a plug-in box, which includes a locking mechanism 100. The specific structure of the locking mechanism 100 is as described in the above embodiments. Since this plug-in box adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0077] The main body 111 of the support member 11 can be a box. The handle 112 is movably mounted on the box, and the locking structure is mounted on the side of the handle 112.

[0078] The linkage mechanism can use an existing locking mechanism to lock the plug-in box onto the busbar trunking. The linkage mechanism includes structures such as hooks and drive components.

[0079] When the plug box needs to be disassembled, an external force must first be applied to the locking member 20 to disengage the locking foot 21 from the first groove 121 on the button 12. Then, the button 12 is moved in the direction of unlocking the linkage mechanism. After the linkage mechanism is unlocked, the external force applied to the locking member 20 is released, so that the locking foot 21 is engaged in the second groove 122 on the button 12. The linkage mechanism remains in the unlocked state, which makes it easier to remove the plug box from the busbar.

[0080] This application also proposes a power distribution system, which includes a plug-in box and a busbar trunking, wherein the plug-in box is locked to the trunking of the busbar trunking, or the plug-in box is detached from the trunking of the busbar trunking.

[0081] The above description is merely an exemplary embodiment of this application and does not limit the scope of protection of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
