Technical Field

[0001] The invention relates to the technical field of distribution boxes, in particular to a distribution box with a built-in bus duct. Background Art

[0002] The distribution box is an important component in the power system. It is a closed metal cabinet or box used to receive and distribute electrical energy. It contains various electrical components such as circuit breakers, fuses, switches, measuring instruments, etc. These components are used to control, protect and distribute electricity to different circuit branches.

[0003] In standard distribution boxes, modules such as miniature circuit breakers (MCBs) and residual current circuit breakers (RCCBs) are usually installed on rails. However, this installation method is complicated to operate in the narrow space of the distribution box, limiting the range of operators' activities, making it difficult to significantly simplify the installation and removal process while ensuring reliable electrical connections. Summary of the invention

[0006] By adopting the above technical solution, the bus trough is installed on the mounting plate, the mounting plate is fixed on the fixed side plate, and finally the fixed side plate is installed on the inner wall of the distribution box; this nested method ensures the stability and safety of the bus trough in the distribution box; multiple copper bars are placed inside the bus trough, and each copper bar is responsible for transmitting different power loads, thereby realizing independent control and protection of different circuits; specifically, based on the quick plug-in assembly, the bus trough and the distribution module are quickly assembled and unassembled; the design utilizes a precise mechanical snap-fit ​​structure to significantly simplify the installation and disassembly process while ensuring reliable electrical connection.

[0007] Preferably, a cover plate is provided on the top of the distribution box body, and one end of the cover plate is rotatably connected to the distribution box body via a hinge.

[0008] By adopting the above technical solution and a simple hinge mechanism, the cover can be easily opened, thereby facilitating the status inspection, replacement and maintenance of internal components, eliminating tedious disassembly steps.

[0009] Preferably, the quick plug-in assembly comprises a locking block fixed inside the bus trough body and a plug-in rod arranged on the power distribution module, and a slot matching the plug-in rod is arranged inside the locking block.

[0010] By adopting the above technical solution, a locking block is provided in the bus duct body, which has a slot with a geometric shape matching that of the plug-in rod; this plug-in structure ensures convenient connection and disconnection operations, which can be completed with simple plug-in and pull-out actions.

[0011] Preferably, a branch groove is provided inside the locking block, and the branch groove is an arc-shaped structure, and the branch groove is arranged tangent to the long side direction of the slot. An insert claw block is slidably provided inside the branch groove of the locking block, and a first bite groove is provided on the insert claw block, and a second bite groove matching the first bite groove is provided on the insert rod. When the insert rod is inserted into the slot of the locking block and connected with the insert claw block, the first bite groove on the insert claw block is engaged and connected with the second bite groove on the insert rod by sliding the insert claw block.

[0012] By adopting the above technical solution, after the plug rod is inserted to the set depth, it contacts the plug claw block. Subsequently, through the sliding of the plug claw block, the second bite groove of the plug rod and the first bite groove of the plug claw block are mechanically engaged to form a secondary locking mechanism, which enhances the reliability of anti-vibration and external force impact; the design of the arc-shaped branch groove optimizes the sliding path of the plug claw block to ensure a smooth and reliable engagement process.

[0013] Preferably, a first spring is provided in the branch groove of the locking block.

[0014] By adopting the above technical solution, the preload spring continuously acts on the plug-in claw block to provide a preload force for the engagement mechanism; this preload force ensures that the plug-in rod and the plug-in claw block remain stable in the engaged state, and effectively resists loosening caused by external factors such as vibration and impact.

[0015] Preferably, a second spring is provided in the slot of the locking block, one end of the second spring is fixedly connected to the locking block, and the other end of the second spring is connected to a stop block; a plane is provided on the upper surface of the stop block, and when the plug-in rod is disconnected from the slot, the second spring pushes the stop block so that the plane on the stop block is at a tangent position between the branch slot and the slot, so that the plug-in claw block is blocked inside the branch slot.

[0016] By adopting the above technical solution, after the connecting rod is disengaged from the slot, the preload force of the preloaded second spring is insufficient to overcome the return force of the connecting claw block; at this time, the released elastic potential energy of the second spring pushes the abutment block so that its flat surface abuts against the connecting claw block, ensuring that the connecting claw block is reliably retained in the branch groove.

[0017] Preferably, the upper surface of the stop block is provided with a first inclined surface, and the first inclined surface is located on one side of the plane.

[0018] By adopting the above technical solution, when the plug-in rod is inserted, the stop block is pushed away; when the plug-in rod is pulled out, the second spring drives the stop block, and its flat surface first contacts the plug-in claw block to provide initial resistance; then, the first inclined surface guides the stop block to apply an inclined force to the plug-in claw block, pushing the plug-in claw block smoothly into the branch groove.

[0019] Preferably, a guide block is provided in the busbar trough body of the mounting plate, an indicator light is provided on the top of the guide block, a push-type switch is provided at the bottom of the indicator light, the guide block is an arc-shaped structure, and an arc-shaped hole is provided inside the guide block, the push-type switch is located inside the arc-shaped hole, and a touch rod is provided on the top of the plug-in claw block, the touch rod is an arc-shaped structure, and the touch rod slides inside the arc-shaped hole and contacts with the push-type switch.

[0020] By adopting the above technical solution, after the plug-in claw block is connected to the bus duct, the touch rod moves down, the switch is disconnected, and the indicator light goes out; conversely, when the plug-in claw block is pulled out, the touch rod slides along the arc hole in the guide block, pushing the switch to close, and the indicator light lights up, intuitively indicating the connection status.

[0021] Preferably, a conductive wire is provided at the bottom of the power distribution module, and a wire harness assembly for fixing the conductive wire is provided on the mounting plate.

[0022] By adopting the above technical solution, the conductive wire is fixed through the wire harness assembly.

[0023] Preferably, the wiring harness assembly includes a cross bar and a driving motor fixed on a mounting plate, the output end of the driving motor is connected to a first gear, one side of the first gear is meshingly connected to a second gear, a columnar block is arranged at the bottom center position of the second gear, the cross-section of the columnar block is an elliptical structure, the two ends of the cross bar are respectively rotatably connected to a first clamping rod and a second clamping rod, the middle part of the first clamping rod and the middle part of the second clamping rod are hingedly arranged between the cross bar, one end of the first clamping rod and the second clamping rod are respectively located on both sides of the columnar block, and the other end of the first clamping rod and the other end of the second clamping rod are respectively provided with a first clamping block and a second clamping block.

[0024] By adopting the above technical solution, the motor drives the gear transmission mechanism, wherein the eccentrically rotating elliptical cylindrical block drives the articulated clamping rod system; the elliptical motion trajectory generated by the eccentric rotation is converted into the relative motion of the first clamping block and the second clamping block, thereby realizing the precise clamping and loosening of the conductive wire; the design of the elliptical cylindrical block ensures the smooth change of the clamping force and the stability of the clamping action.

[0025] In summary, this application has the following beneficial effects: 1. The bus trough is installed on the mounting plate, the mounting plate is fixed on the fixed side plate, and finally the fixed side plate is installed on the inner wall of the distribution box; this nested method ensures the stability and safety of the bus trough in the distribution box; multiple copper bars are placed inside the bus trough, and each copper bar is responsible for transmitting different power loads, thereby realizing independent control and protection of different circuits; specifically, based on the quick plug-in assembly, the bus trough and the distribution module can be quickly assembled and unassembled; the design uses a precise mechanical snap-fit ​​structure to significantly simplify the installation and disassembly process while ensuring reliable electrical connection.

[0026] 2. The driving motor drives the first gear to rotate, and drives the second gear to rotate through the first gear transmission; since the cylindrical block on the second gear is elliptical, when the cylindrical block rotates, its center point moves along an elliptical trajectory; this elliptical motion is transmitted through the hinge structure of the first clamping rod and the second clamping rod, and finally the first clamping block and the second clamping block produce relative motion, thereby clamping or releasing the conductive wire through the first clamping block and the second clamping block; the elliptical cylindrical block ensures the change of the clamping force and the smoothness of the clamping action.

DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0029] The present invention discloses a distribution box with a built-in bus duct, such as Figure 1 and Figure 2 As shown, it includes a distribution box body 1, a cover plate 2 is arranged on the top of the distribution box body 1, one end of the cover plate 2 is rotatably connected to the distribution box body 1 through a hinge 3, and the distribution box body 1 is a closed metal or plastic shell for protecting the internal electrical components; the cover plate 2 is connected to the distribution box body 1 through the hinge 3, and can be easily opened and closed to facilitate access to the internal circuit breakers, switches, sockets and other electrical components; this design avoids the need to disassemble the entire distribution box for inspection or maintenance, greatly improving the operating efficiency and convenience.

[0030] like Figure 1 and Figure 2 As shown, through the simple hinge 3 design, the cover 2 can be easily opened to check the status of the internal components and to replace or repair them without complicated disassembly process.

[0031] like Figure 1 and Figure 2 As shown, a door panel 4 is provided on the front side of the distribution box body 1, and the door panel 4 is rotatably arranged between the distribution box body 1. By flipping the door panel 4, the front opening of the distribution box is opened or closed; opening the door panel 4 can conveniently access the electrical components inside the distribution box, while closing the door panel 4 can protect the internal components and prevent accidental contact.

[0032] like Figure 2 and Figure 3 As shown, a fixed side plate 5 is fixedly installed on the inner wall of the distribution box 1, a mounting plate 6 is arranged on the fixed side plate 5, a mounting hole 7 is arranged on the mounting plate 6, a bus trough is installed inside the mounting hole 7 of the mounting plate 6, and a plurality of copper bars are arranged inside the bus trough, which are used to transmit different electrical energy loads.

[0033] like Figure 2 and Figure 3 As shown, the bus trough is installed on the mounting plate 6, the mounting plate 6 is fixed on the fixed side plate 5, and finally the fixed side plate 5 is installed on the inner wall of the distribution box; this nested method ensures the stability and safety of the bus trough in the distribution box; multiple copper bars are placed inside the bus trough, and each copper bar is responsible for transmitting different power loads, thereby realizing independent control and protection of different circuits.

[0034] like Figure 2 and Figure 3 As shown, the bus duct concentrates a large number of wires in one structure, avoiding the disorderly distribution of the wires in the distribution box, improving the cleanliness and aesthetics of the interior of the distribution box, and facilitating future maintenance and inspection.

[0035] like Figure 2 and Figure 3 As shown, the fixed side plate 5 and the mounting plate 6 are fixedly connected by bolts, so as to firmly fix the fixed side plate 5 and the mounting plate 6 on the inner wall of the distribution box 1 .

[0036] like Figure 2 and Figure 3 As shown, a power distribution module 8 is inserted into the bus trough body of the mounting plate 6, and a quick plug-in assembly 9 is provided between the power distribution module 8 and the bus trough body. The quick plug-in assembly 9 is used to establish a quick assembly and disassembly between the bus trough body and the power distribution module 8. The core of the quick plug-in assembly is to utilize the mechanical principles of the mechanical structure through a certain snap-in method; while ensuring the reliability of the electrical connection, the installation and disassembly process is simplified.

[0037] like Figure 4 and Figure 5 As shown, specifically, the quick plug-in assembly 9 includes a locking block 901 fixed inside the bus trough body and a plug-in rod 902 arranged on the distribution module 8, the locking block 901 is provided with a slot 903 matching the plug-in rod 902 inside, the locking block 901 is fixed in the bus trough body, and is provided with a slot 903 matching the shape of the plug-in rod 902 inside; the matching design of the plug-in rod 902 and the slot 903 makes connection and disconnection very simple, and it can be completed with a simple insertion and removal action.

[0038] like Figure 4 and Figure 5 As shown, a branch groove 904 is provided inside the locking block 901, and the branch groove 904 is an arc-shaped structure, and the branch groove 904 is tangent to the long side direction of the slot 903. A plug-in claw block 905 is slidably provided inside the branch groove 904 of the locking block 901, and a first bite groove 906 is provided on the plug-in claw block 905. A second bite groove 907 matching the first bite groove 906 is provided on the plug-in rod 902. When the plug-in rod 902 is inserted into the slot 903 of the locking block 901 and connected with the plug-in claw block 905, the first bite groove 906 on the plug-in claw block 905 is engaged and connected with the second bite groove 907 on the plug-in rod 902 by sliding the plug-in claw block 905.

[0039] like Figure 4 and Figure 5 As shown, the plug-in rod 902 is first inserted into the slot 903 of the locking block 901, and the arc-shaped branch groove 904 guides the plug-in rod 902 into the correct direction and position; the design of the branch groove 904 being tangent to the long side of the slot 903 can ensure that the plug-in rod 902 enters the slot 903 smoothly and prevents misalignment.

[0040] like Figure 4 and Figure 5 As shown, when the plug rod 902 is inserted to a certain depth, it will contact the plug claw block 905; by sliding the plug claw block 905, the second bite groove 907 on the plug rod 902 and the first bite groove 906 on the plug claw block 905 bite together to form an additional mechanical locking mechanism; this bite action provides additional fixing force to prevent the plug rod 902 from loosening or falling off due to vibration or other external forces; the design of the arc-shaped branch groove 904 helps to guide the sliding of the plug claw block 905 and ensure the smooth progress of the bite process.

[0041] like Figure 4 and Figure 5 As shown, compared with the locking relying solely on the shape of the slot 903, the addition of the bite structure significantly improves the locking force of the connection, allowing it to withstand greater vibration and impact; the dual locking mechanism of the slot 903 and the bite significantly improves the reliability of the connection and reduces the risk of accidental detachment.

[0042] like Figure 4 and Figure 5 As shown, a first spring 908 is provided in the branch groove 904 of the locking block 901, and the first spring 908 continuously applies a pre-pressure to the plug-in claw block 905; when the plug-in rod 902 is inserted and engaged with the plug-in claw block 905, the pre-pressure of the first spring 908 helps to maintain the engaged state and prevent the engaging mechanism from loosening due to vibration, impact or other external forces; even if subjected to external force, the elastic force of the first spring 908 will try to keep the plug-in claw block 905 in the engaged state with the plug-in rod 902.

[0043] like Figure 4 and Figure 5 As shown, a second spring 909 is provided in the slot 903 of the locking block 901, one end of the second spring 909 is fixedly connected to the locking block 901, and the other end of the second spring 909 is connected to a stop block 9010; a plane 9011 is provided on the upper surface of the stop block 9010, and when the plug-in rod 902 is disconnected from the slot 903, the second spring 909 pushes the stop block 9010 so that the plane 9011 on the stop block 9010 is at a tangent position between the branch slot 904 and the slot 903, so that the plug-in claw block 905 is blocked inside the branch slot 904.

[0044] like Figure 4 and Figure 5 As shown, when the plug rod 902 is disengaged from the slot 903, the preload force provided by the first spring 908 still exists, but it is not enough to completely overcome the disengagement tendency of the plug claw block 905; at this time, the second spring 909 plays a role; due to the disengagement of the plug rod 902, the second spring 909 is no longer constrained by the plug rod 902, and its elastic potential energy is released; the second spring 909 pushes the block 9010, so that the plane 9011 of the block 9010 abuts against the plug claw block 905, and the plug claw block 905 is firmly engaged. The ground is "pressed" in the branch groove 904; the contact between the flat surface 9011 of the block 9010 and the branch groove 904 and the slot 903 forms an effective mechanical barrier to prevent the plug-in claw block 905 from being accidentally pushed out; this design is "active" rather than relying solely on the passive retention of the first spring 908; the first spring 908 ensures stability during insertion, while the second spring 909 ensures safety after disengagement to avoid accidental popping out of the plug-in claw block 905; this is crucial for applications with high safety requirements.

[0045] like Figure 4 and Figure 5 As shown, the upper surface of the stop block 9010 is provided with a first inclined surface 9012 , which is located on one side of the plane 9011 . The first inclined surface 9012 is used to slowly guide and push the plug-in claw block 905 so that the plug-in claw block 905 faces the inside of the branch groove 904 .

[0046] like Figure 4 and Figure 5As shown, when the plug rod 902 is inserted, the stopper 9010 will be pushed away; when the plug rod 902 is pulled out, the second spring 909 pushes the stopper 9010, and the plane 9011 on the stopper 9010 first contacts the plug claw block 905 to provide an initial blocking force; then, the first inclined surface 9012 starts to act; due to the inclination angle of the first inclined surface 9012, the force exerted by the stopper 9010 on the plug claw block 905 is no longer vertical, but an inclined component force; this inclined component force slowly guides the plug claw block 905 And push it into the interior of the branch groove 904; the angle of the inclined surface determines the speed and force of the push, which can be adjusted as needed to achieve fine control of the plug-in claw block 905; the whole process is gradual, avoiding sudden impact or jamming; the slow-release action guided by the first inclined surface 9012 avoids severe impact between the plug-in claw block 905 and the branch groove 904, reducing wear and damage; and a smoother plug-in process reduces the possibility of connection failure due to impact and improves the reliability of the connection.

[0047] like Figure 4 and Figure 5 As shown, a guide block 9013 is provided in the busbar trough body of the mounting plate 6, an indicator light 9014 is provided on the top of the guide block 9013, a push switch is provided on the bottom of the indicator light 9014, the guide block 9013 is an arc-shaped structure, and an arc-shaped hole is provided inside the guide block 9013, the push switch is located inside the arc-shaped hole, a touch rod 9015 is provided on the top of the plug-in claw block 905, the touch rod 9015 is an arc-shaped structure, and the touch rod slides inside the arc-shaped hole and contacts with the push switch.

[0048] like Figure 4 and Figure 5 As shown, when the plug-in claw block 905 is inserted and connected to the bus duct, the touch rod 9015 moves downward and leaves the switch, and the indicator light 9014 goes out; conversely, when the plug-in claw block 905 is pulled out, the arc-shaped touch rod 9015 on its top will slide along the arc-shaped hole inside the guide block 9013; this sliding action will push the push switch, thereby lighting up the indicator light 9014 to indicate the connection status; the indicator light 9014 directly shows whether the plug-in claw block 905 has been correctly connected to the bus duct, which is very intuitive and convenient for users to judge.

[0049] like Figure 4 and Figure 5 As shown, no additional operation steps are required to confirm the connection status, and the insertion or removal action of the plug-in claw block 905 itself completes the status indication.

[0050] like Figure 4 and Figure 5As shown, in summary, this design realizes automatic indication and feedback of the connection status through clever mechanical linkage, improving the reliability and usability of the system; the choice of the arc structure further optimizes the coordination between the touch rod 9015 and the switch, ensuring the reliability and stability of the action.

[0051] like Figure 6 and Figure 7 As shown, a conductive wire 10 is provided at the bottom of the power distribution module 8, and a wire harness assembly 11 for fixing the conductive wire 10 is provided on the mounting plate 6. Specifically, the wire harness assembly 11 includes a crossbar 1101 and a drive motor 1102 fixed on the mounting plate 6. The output end of the drive motor 1102 is connected to a first gear 1103, and one side of the first gear 1103 is meshedly connected to a second gear 1104. A columnar block 1105 is provided at the bottom center of the second gear 1104, and the cross section of the columnar block 1105 is an ellipse. The circular structure has a first clamping rod 1106 and a second clamping rod 1107 which are rotatably connected at both ends of the cross bar 1101. The middle part of the first clamping rod 1106 and the middle part of the second clamping rod 1107 are hingedly arranged with the cross bar 1101. One end of the first clamping rod 1106 and the second clamping rod 1107 are respectively located on both sides of the columnar block 1105. The other end of the first clamping rod 1106 and the other end of the second clamping rod 1107 are respectively provided with a first clamping block 1108 and a second clamping block 1109.

[0052] like Figure 6 and Figure 7 As shown, the driving motor 1102 drives the first gear 1103 to rotate, and drives the second gear 1104 to rotate through the first gear 1103; since the cylindrical block 1105 on the second gear 1104 is elliptical, when the cylindrical block 1105 rotates, its center point moves along an elliptical trajectory; this elliptical motion is transmitted through the hinge structure of the first clamping rod 1106 and the second clamping rod 1107, and finally the first clamping block 1108 and the second clamping block 1109 produce relative motion, thereby clamping or releasing the conductive wire 10 through the first clamping block 1108 and the second clamping block 1109; the elliptical cylindrical block 1105 ensures the change of the clamping force and the smoothness of the clamping action.

[0053] like Figure 6 and Figure 7 As shown, a third spring is provided between the first clamping rod 1106 and the second clamping rod 1107 for resetting the first clamping rod 1106 and the second clamping rod 1107 .

[0054] like Figure 6 and Figure 7As shown, the rotational movement of the elliptical cylindrical block 1105 can provide a stable clamping force to ensure that the conductive wire 10 is firmly fixed on the mounting plate 6; compared with some simple linear clamping mechanisms, this design can achieve a smoother clamping and releasing process and reduce damage to the conductive wire 10.

[0055] like Figure 6 and Figure 7 As shown, in summary, this design achieves a reliable, smooth and adjustable wiring function for the conductive wires 10 through an ingenious mechanical structure, thereby improving the reliability and service life of the power distribution module 8.

[0056] like Figure 7 As shown, the inner surfaces of the first clamping block 1108 and the second clamping block 1109 are both provided with a semicircular fitting surface 11010. When the first clamping block 1108 and the second clamping block 1109 are in a closed state, the fitting surfaces 11010 of the first clamping block 1108 and the second clamping block 1109 are consistent with the surface of the conductive wire 10.

[0057] like Figure 7 As shown, the semicircular fitting surface 11010 can better adapt to the circular cross-section of the conductive wire 10, and can ensure a larger contact area even if the position of the conductive wire 10 is slightly offset or there is a slight bend; compared with the flat surface 9011 fitting, this curved surface fitting can effectively reduce local stress, avoid damage to the conductive wire 10, and improve the clamping stability to prevent the conductive wire 10 from slipping; the semicircular fitting surface 11010 increases the contact area and provides stronger friction, effectively preventing the conductive wire 10 from loosening or falling off, especially in a vibration or impact environment.

[0058] Working principle: When in use, the user first places the conductive wire 10 on the distribution module 8 between the first clamping block 1108 and the second clamping block 1109, and starts the drive motor 1102, which drives the first gear 1103 to rotate, and drives the second gear 1104 to rotate through the first gear 1103; since the cylindrical block 1105 on the second gear 1104 is elliptical, when the cylindrical block 1105 rotates, its center point moves along an elliptical trajectory; this elliptical motion is transmitted through the hinge structure of the first clamping rod 1106 and the second clamping rod 1107, and finally causes the first clamping block 1108 and the second clamping block 1109 to produce relative motion, thereby clamping or releasing the conductive wire 10 through the first clamping block 1108 and the second clamping block 1109; the elliptical cylindrical block 1105 ensures the change of the clamping force and the smoothness of the clamping action.

[0059] Then align the plug-in rod 902 on the distribution module 8 with the slot 903 in the locking block 901 and press it toward the inside of the slot 903 to insert it. When the plug-in rod 902 is inserted to an appropriate depth, it will contact the plug-in claw block 905. By sliding the plug-in claw block 905, the second bite groove 907 on the plug-in rod 902 bites with the first bite groove 906 on the plug-in claw block 905 to form an additional mechanical locking mechanism. This bite action provides additional fixing force to prevent the plug-in rod 902 from loosening or falling off due to vibration or other external forces.

[0060] At this time, when the plug-in claw block 905 is inserted and connected to the bus duct, the touch rod 9015 moves downward and leaves the switch, and the indicator light 9014 goes out.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
