In the face of the powerful current of hundreds or thousands of amperes required by this huge load, safe and reliable conduction equipment must be selected. The busbar system is a good choice. The busbar duct system is a distribution device that efficiently transmits current. It is especially adapted to the needs of economical and reasonable wiring of increasingly tall buildings and large-scale factories. Due to the need for electricity in various buildings such as buildings and factories, and this need has a trend of increasing year by year, the use of the original circuit wiring method, that is, the pipe wiring method, brings many difficulties during construction. Moreover, when the distribution system needs to be changed, it is almost impossible to make it simpler. However, if the busbar duct is used, the purpose can be achieved very easily, and the building can also be made more beautiful.

[0003] When assembling the existing bus duct, it generally has two end faces. During installation, the two bus ducts are directly connected and fixed. When multiple passages need to be installed, it is necessary to lead out another installation passage of the bus duct, which not only increases the cost but also increases the occupancy rate of the installation space, thereby increasing the subsequent maintenance cost. In addition, when connecting the bus duct, bolts are used for connection and fixing, so that the staff needs to carry different operating tools during installation, thereby increasing the labor intensity of the staff and reducing the installation efficiency. Therefore, the present invention proposes a multi-head quick-connect air-type bus duct and an assembly method thereof. Summary of the invention

10. An assembly method of a multi-head quick-connect air-type bus duct according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, a plug-in male connector (5) is bolted to one end of a conductive copper busbar (1) inside a busbar duct, and a plurality of plug-in female connectors (6) are installed on the other plurality of ends of the conductive copper busbar (1); S2, then the two bus ducts to be connected are connected to the inside of the plug-in female connector (6) of the other bus duct through the plug-in male connector (5) provided on one end; S3, then the plug-in boards (54) on both sides of the male connector (5) are inserted along the inner wall of the protective frame (63), so that the limiting grooves (57) provided on the outer wall are pressed against the limiting spring pieces (638) inside the protective frame (63), so that the protrusions (6381) provided on the inner wall of the limiting spring pieces (638) are embedded in the limiting grooves (57), thereby enabling the plug-in boards (54) to be pre-positioned and fixed; S4, then continue to push the plug board (54) so ​​that it is stuck on the positioning block (641) through the plug slots (55) on both sides, and the inner wall of the plug slot (55) squeezes the clamping columns (645) on both sides so that they slide on the positioning block (641) and squeeze the internal spring (647). When the clamping slot (56) corresponds to the clamping column (645), the end face of the clamping column (645) can be clamped and connected to the inside of the clamping slot (56) by utilizing the restoring elasticity of the internally compressed spring (647), so that the plug male connector (5) can be fixed, and at the same time, the conductive copper bars (1) inside the two connected bus ducts can be energized through the internally squeezed contact piece (62); S5, finally, the protective frame (63) is slid inside the slide groove (611) through the internal slide bar (631), and the protective frame (63) is slid to the position of the boss (52), and the limiting spring piece (638) is slid and adjusted on the limiting groove (57) to be positioned at the position where the protective frame (63) moves, thereby protecting the contact position of the plug-in male connector (5) and the plug-in female connector (6), and realizing the quick connection operation of the multi-head bus duct; S6. When multiple bus ducts need to be disassembled and repaired at a later stage, the adjusting bolt (636) is firstly used to thread the protective frame (63) to press the pressing block (634), so that the sleeve (633) can rotate on the positioning shaft (632), so that the tilting rod (637) drives the limiting spring sheet (638) on the end surface to bend, so that the protrusion (6381) can be away from the limiting groove (57) on the plug-in board (54), and the adjusting nut (639) can be used to bend the limiting spring sheet (638) on the tilting rod (637) to a certain extent to keep it away from the limiting groove (57), and the protective frame (63) is slid onto the plug-in frame (61); S7, the knob (643) is then rotated to drive the rotating rod (644) to rotate, thereby driving the push column (6441) on its end surface to move inside the adaption groove (6451) provided on the top of the clamping column (645), thereby driving the clamping column (645) to slide, so that the end surface of the clamping column (645) is away from the clamping groove (56); S8. Finally, the bus duct that needs maintenance can be disassembled by simply pulling out the plugged-in bus duct from the plugged-in female connector (6) by plugging in the male connector (5).
