Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-5 A waterproof bus duct connector that is easy to install and maintain, comprising two bus duct bodies 1, the outer sides of the two bus duct bodies 1 are respectively installed with a first plug connector 7 and a second plug connector 8, each bus duct body 1 is installed with a wire row 6, and the first plug connector 7 and the second plug connector 8 are electrically connected to the wire row 6 corresponding to the position, and the first plug connector 7 and the second plug connector 8 are staggered. A square sleeve 2 is fixedly installed on the outer side of one bus duct body 1, and a square sleeve 2 is fixed on the outer side of the other bus duct body 1. A fixing sleeve 3 is installed, and multiple fixing plates 5 are symmetrically installed on the outside of the fixing sleeve 3. Each fixing plate 5 is elastically connected with a pin 14, and each pin 14 is clamped in the square sleeve 2. Multiple clamping columns 10 are installed in the fixing sleeve 3, and each clamping column 10 is clamped in the square sleeve 2. An inflatable sealing strip 9 is installed on the inside of the fixing sleeve 3, and a sleeve 4 is fixedly installed on the top surface of the fixing sleeve 3. An airbag 16 is installed in the sleeve 4, and the airbag 16 is communicated with the inflatable sealing strip 9. An extrusion mechanism is provided in the sleeve 4.

[0027] like Figure 1-5 As shown, the specific implementation method is: by setting a square sleeve 2, a fixed sleeve 3, a fixed plate 5, and a pin 14, the pin 14 can fix the fixed sleeve 3 and the square sleeve 2, and at the same time, by setting the clamping column 10, the fixed sleeve 3 limits the square sleeve 2, and through the extrusion mechanism and the inflatable sealing strip 9, the connection between the fixed sleeve 3 and the square sleeve 2 can be sealed to improve the waterproof performance.

[0028] The extrusion mechanism includes a threaded rod 11 , and the threaded rod 11 is threadedly connected to the top surface of the sleeve 4 , the bottom surface of the threaded rod 11 is rotatably connected to the pressure plate 15 , and the top surface of the threaded rod 11 is fixedly mounted with a knob 22 .

[0029] It is worth noting that the thread is self-locking, so when the threaded rod 11 stops rotating, the position of the pressing plate 15 is fixed.

[0030] Second springs 20 are fixedly mounted on both inner sides of the square sleeve 2 , and an insulating plate 21 is fixedly mounted on the other end of each second spring 20 , and each insulating plate 21 abuts against the outer side of the first plug connector 7 .

[0031] The action of the second spring 20 allows the first plug connector 7 to be in close contact with the second plug connector 8, thereby facilitating reduced resistance and maintaining good electrical conductivity.

[0032] A baffle 12 is fixedly mounted on the top surface of each pin 14 , and a first spring 13 is commonly mounted between the bottom surface of each baffle 12 and the outer side of the corresponding fixed plate 5 .

[0033] The pin 14 is firmly fixed in the square sleeve 2 by the action of the first spring 13 , and is easy to assemble and disassemble.

[0034] A strip groove 19 is provided on the outside of the square sleeve 2 , and the strip groove 19 is arranged around the outside of the square sleeve 2 , and the inflation sealing strip 9 is clamped in the strip groove 19 .

[0035] First slots 17 are provided on both the upper and lower outer sides of the square sleeve 2 , and each pin 14 is locked in the first slot 17 at the corresponding position.

[0036] The diameter of each baffle 12 is greater than the diameter of the first spring 13 at the corresponding position.

[0037] A plurality of second slots 18 are formed on the side surface of the square sleeve 2 , and each of the latching posts 10 is latched in a second slot 18 corresponding to the position thereof.

[0038] When the utility model is used, the first plug connectors 7 and the second plug connectors 8 of the two bus duct bodies 1 are first interlaced and plugged in. At this time, the square sleeve 2 slides into the fixed sleeve 3, and then the pin 14 is pulled outward. Then, under the action of the first spring 13, the pin 14 is clamped into the first clamping groove 17 provided on the square sleeve 2, thereby achieving the initial fixation of the square sleeve 2 and the fixed sleeve 3. While sliding, multiple clamping columns 10 are inserted into the second clamping groove 18, and then the square sleeve 2 is limited and fixed by the clamping columns 10, thereby achieving the second step of fixing the square sleeve 2 and the fixed sleeve 3;

[0039] Then the threaded rod 11 can be screwed to drive the pressure plate 15 to move downward and squeeze the airbag 16, so that the gas in the airbag 16 is released into the inflatable sealing strip 9, causing the inflatable sealing strip 9 to expand and fill the strip groove 19, thereby sealing the connection between the square sleeve 2 and the fixed sleeve 3, preventing external water from entering the bus duct body 1 through the gap, and protecting the bus duct body 1.
