A support plate 3 is detachably installed inside the disassembly groove 12. The support plate 3 and the metal shell 1 form a complete shell, which can form an effect similar to a Faraday cage to prevent the surrounding materials from generating inductive charging. It should be noted that during installation, multiple devices are connected through a bus duct connection device, and each bus duct needs to be reliably electrically connected to the ground.

[0027] The bearing kit 4 includes an installation kit 40, a top plate 41 is provided above the installation kit 40, the end of the top plate 41 is rotatably mounted on one end of the upper surface of the installation kit 40, a second slot 49 is provided at the other end of the upper surface of the installation kit 40, a first disassembly plate 44 is provided at one end of the top plate 41, a connecting rod 441 is fixedly mounted in the middle of the lower surface of the first disassembly plate 44, a third clamping block 443 is fixedly mounted at the bottom end of the connecting rod 441, a slot is provided inside the first disassembly plate 44, the connecting rod 441 and the third clamping block 443 are both slidably mounted inside the slot, a second spring 442 is sleeved on the outside of the connecting rod 441, both ends of the second spring 442 are fixedly mounted on the third clamping block 443 and inside the slot, a plurality of placement slots 46 corresponding to the conductor busbars 2 are provided in the middle of the installation kit 40, a plurality of conductor busbars 2 are placed inside the corresponding placement slots 46, and rubber blocks 47 are fixedly mounted on both side surfaces of the inside of the placement slots 46.

[0028] In actual use, first pinch the first disassembly plate 44 to drive the third clamping block 443 to move upward, so that the third clamping block 443 slides out from the inside of the second clamping slot 49, rotate the top plate 41, at this time the placement slot 46 is in an open state, put the conductor bus 2 into the corresponding placement slot 46, wait for the placement to be completed, rotate the top plate 41 so that the third clamping block 443 is clamped into the inside of the second clamping slot 49, install all the multiple bearing kits 4, and then the conductor bus 2 can be limited and supported.

[0031] After the conductor bus 2 has been used for a period of time, its connection is prone to wear, which in turn causes the connection resistance of multiple conductor busbars 2 to increase and the conductive effect to decrease. At this time, it needs to be repaired or replaced. You only need to take out the support plate 3 first, and then pinch the lever 421. At this time, the first clamping block 42 is driven to slide out from the inside of the first clamping slot 14, and the conductor bus 2 and the bearing kit 4 can be removed as a whole.

Multiple groups of second card blocks 48 are also installed at corresponding positions on the top plate 41. Because the device is used in different scenarios, the current and voltage inside it are different. When the internal voltage is higher, an insulating plate can be inserted into the second card block 48 to increase the insulation performance between the multiple conductor busbars 2.
