A reinforcing assembly 6 is fixedly installed on one side of the junction box body 1. The disassembly / removal assembly 3 includes a slot 31 and a sliding groove 32. The slot 31 is located on the top of the top cover 2, and the sliding groove 32 is located on one side of the junction box body 1. A spring 33 is provided on the inner wall of the sliding groove 32, and one end of the spring 33 is fixedly connected to a movable... The movable plate 34 is engaged with the slot 31. A slot 35 is fixedly installed on one side of the movable plate 34. The slot 35 is located above the top cover 2. A positioning rod 4 is fixedly installed on the top of the junction box body 1. A positioning groove 5 is opened on the top of the top cover 2. The positioning groove 5 is engaged with the positioning rod 4. The disassembly and assembly assembly 3 also includes a pull plate 36, which is fixedly installed on one side of the movable plate 34. The disassembly and assembly assembly 3 also includes an anti-slip pad 37, which is disposed on one side of the pull plate 36.

[0033] In this embodiment, when the assembly / disassembly component 3 is working, the top cover 2 first engages the positioning groove 5 with the positioning rod 4 on the top of the junction box body 1 to achieve initial positioning. The moving plate 34 is pushed to slide along the slide groove 32 and compress the spring 33. After the top cover 2 is attached to the body, it is released. The spring 33 returns to its original position, causing the moving plate 34 to engage with the slot 31. The locking plate 35 covers the top cover 2 to form a double fixation. When disassembling, the pull plate 36 is pulled to move the moving plate 34 away from the slot 31. The anti-slip pad 37 prevents the hand from slipping. Then the positioning groove 5 and the positioning rod 4 are separated. The top cover 2 can be quickly disassembled and assembled without tools, reducing the difficulty of maintenance.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the reinforcement component 6 includes a conduit 61 fixedly connected to one side of the junction box body 1. The reinforcement component 6 also includes a fixing plate 62 and a threaded rod 63. The fixing plate 62 is fixedly installed on one side of the junction box body 1. The threaded rod 63 is connected to the top of the fixing plate 62 via a bearing. A lifting plate 64 is threadedly connected to the side wall of the threaded rod 63. An arc-shaped plate 65 is fixedly installed on the top of the lifting plate 64, and the arc-shaped plate 65 is located below the conduit 61. A locking rod 66 is fixedly installed on the top of the arc plate 65, and a reinforcing plate 67 is fixedly connected to the side wall of the conduit 61. The locking rod 66 and the reinforcing plate 67 are interlocked. The reinforcing component 6 also includes a knob 68 and a stabilizing rod 69. The knob 68 is fixedly connected to the top of the threaded rod 63, and the stabilizing rod 69 is fixedly connected to the top of the fixed plate 62. The lifting plate 64 is slidably connected to the stabilizing rod 69. Two mounting plates 7 are fixedly installed on both sides of the junction box body 1, and the two mounting plates 7 are arranged opposite each other.

[0035] In this embodiment, in the reinforcement component 6, after the cable passes through the conduit 61, rotating the knob 68 drives the threaded rod 63 to rotate on the bearing of the fixed plate 62. The lifting plate 64, because it is threadedly connected to the threaded rod 63 and slides along the stabilizing rod 69, will rise vertically and drive the arc plate 65, so that the clamping rod 66 is engaged with the reinforcement plate 67 on the side wall of the conduit 61, fixing the conduit 61 to prevent bending. During the overall installation, it is fixed with bolts by the mounting plates 7 on both sides of the junction box body 1 to distribute the weight and prevent loosening.

[0036] Working principle: When disassembling and assembling component 3, the top cover 2 is first installed by engaging the positioning groove 5 with the positioning rod 4 on the top of the junction box body 1 to achieve initial positioning. The moving plate 34 is pushed to slide along the slide groove 32 and compress the spring 33. After the top cover 2 is attached to the body, it is released. The spring 33 returns to its original position, causing the moving plate 34 to be engaged in the slot 31. The retaining plate 35 covers the top cover 2 to form a double fixation. When disassembling, the pull plate 36 is pulled to move the moving plate 34 away from the slot 31. The anti-slip pad 37 prevents the hand from slipping. Then the positioning groove 5 and the positioning rod 4 are separated. The top cover 2 can be quickly disassembled and assembled without tools, reducing the difficulty of maintenance.

[0037] In the reinforcement component 6, after the cable passes through the conduit 61, rotating the knob 68 causes the threaded rod 63 to rotate on the bearing of the fixed plate 62. The lifting plate 64, due to its threaded connection with the threaded rod 63 and its sliding along the stabilizing rod 69, will rise vertically and drive the arc plate 65, so that the clamping rod 66 is engaged with the reinforcement plate 67 on the side wall of the conduit 61, fixing the conduit 61 to prevent bending. During the overall installation, it is fixed with bolts through the mounting plates 7 on both sides of the junction box body 1 to distribute the weight and prevent loosening. All components work together to ensure the neatness and safety of the circuit, provide convenience for maintenance, and realize a stable connection between the inverter and the motor circuit.
