[0002] Bus duct is a device responsible for transmitting and distributing electric energy in low-voltage power supply system. It has many advantages, such as large current carrying capacity, high protection level, convenient distribution of electric energy, compact structure, easy installation and maintenance, long service life, etc. With the development of the times, the improvement of living standards and the progress of industrial automation, the load of electricity is getting bigger and bigger. It has become a development trend to use bus duct to replace cables, especially in hotels, factories, mines, high-rise buildings and public facilities.

[0003] Announcement No.: CN206490394U mentions a shockproof bus duct. The safety protection baffle on the plug interface of the device effectively prevents the entry of dust and foreign matter at the plug interface, thereby improving the protection of the bus duct and preventing misoperation. The safety of the bus is greatly improved. However, in actual use, the safety protection baffle structure in the device is too simple and prone to loosening, which forces the plug interface to leak, affecting its dustproof and protective effects. Now there is an urgent need for a bus duct with a large-section neutral conductor to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a bus duct using a large-section neutral conductor, comprising a bus duct body 1, a fixing box 11, a positioning plate 12 and a shielding sheet 5, a plurality of neutral conductors 3 are installed through the bus duct body 1 through a PVC heat shrink tube 2 and an insulating material layer, a socket seat 8 is installed at the upper end of the bus duct body 1, a plurality of bus duct sockets 9 are opened through the connection between the socket seat 8 and the upper end of the bus duct body 1, and a plurality of bus duct sockets 9 are opened on the left side thereof. A plurality of fixing boxes 11 are provided, and the plurality of fixing boxes 11 are respectively installed at the plurality of bus duct sockets. On the right side of the upper end of 9, corrugated telescopic rubber sheets 13 are stacked at the lower ends of the multiple fixing boxes 11, and elastic cloth sheets 14 are horizontally arranged at the right ends of the multiple fixing boxes 11. The elastic cloth sheets 14 are connected to the return spring 16 through the spring connecting sheet 15. There are multiple positioning plates 12, and strip grooves 6 are opened on the upper sides of the right ends of the multiple positioning plates 12. Card connecting sheets 7 are installed in the multiple strip grooves 6. There are multiple shielding sheets 5. This design solves the problem that the safety protection baffle structure in the original device is too simple and easy to loosen, thereby forcing the socket to leak out, affecting its dustproof and protective effects.

[0020] As the first embodiment of the utility model: connecting plates 4 are installed at the front and rear ends of the left and right sides of the bus duct body 1, and push-pull frames are installed on the upper ends of multiple positioning plates 12. The added push-pull frames make it convenient for staff to pull the multiple positioning plates 12 to move left.

[0021] The right end faces of the multiple positioning plates 12 are fixed to the multiple reset springs 16 and the multiple corrugated telescopic rubber sheets 13 respectively. When the multiple positioning plates 12 are added to move to the left, the multiple reset springs 16 and the multiple corrugated telescopic rubber sheets 13 can be driven to move to the left and stretch. The multiple shielding sheets 5 are slidably located at the upper ends of the multiple fixed boxes 11 respectively. The bus duct sockets 9 can be preliminarily shielded by the added multiple shielding sheets 5. The left ends of the multiple shielding sheets 5 are respectively located in the multiple strip grooves 6, and are movably sleeved on the outside of the multiple card-jointing sheets 7. The added multiple card-jointing sheets 7 can make the multiple shielding sheets 5 movably connected to the multiple positioning plates 12. The lower ends of the multiple positioning plates 12 are all sleeved with anti-skid rubber frames. The added anti-skid rubber frames can be firm when the lower ends of the multiple positioning plates 12 are inserted into the plug-in positioning grooves 10, and are not easy to loosen or fall off by themselves.

[0022] As the second embodiment of the present utility model: when the bus duct socket 9 is not plugged in with a line for dustproof and protective treatment (Note: the bus duct is an existing mature technology, and its principle is not repeated here. The bus duct N phase in this embodiment is twice the phase line), pull the push-pull frame and the positioning plate 12 to the left, and the corrugated telescopic rubber sheet 13 will be driven to stretch to the left, and the return spring 16 and the elastic cloth sheet 14 will be driven to stretch to the left, and the shielding sheet 5 will slowly move to the left in the fixing box 11 until the positioning plate 12 moves to the leftmost end of the bus duct socket 9 and is located directly above the plug-in positioning groove 10, and then press the push-pull frame down so that the lower end of the positioning plate 12 and the anti-slip rubber frame are completely inserted into the plug-in positioning groove 10, the shielding sheet 5 can initially shield the bus duct socket 9, and the corrugated telescopic rubber sheet 13 will also unfold, and cooperate with the shielding sheet 5 to play a dustproof and protective role on the bus duct socket 9.
