DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

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

[0019] See also Figures 1 to 4 The present invention provides a bus duct with stable connection, including a bus duct body 1 and a connection cover 1 2 and a connection cover 2 3 connected to both ends of the bus duct body 1. The connection cover 1 2 is connected to a driving mechanism for driving the connection cover 1 2 to move. The connection cover 1 2 can move, while the connection cover 2 3 is fixedly connected to the bus duct body 1 and the position remains unchanged. A clamping mechanism for clamping the busbar is connected inside the connection cover 1 2. The clamping mechanism includes a moving plate 11, a pressing plate 16, and a spring 18. The spring 18 is used to drive the moving plate 11 to move away from the busbar. The pressing plate 16 is connected to the end of the moving plate 11. The connection cover 1 2 is connected to a guide plate 7 for guiding the connection cover 1 2. The guide plate 7 is used to drive the moving plate 11 to move toward the busbar. The moving plate 11 is connected to a connecting mechanism for improving the stability of the connection between the connection cover 1 2 and the connection cover 2 3.

[0020] When two bus ducts are docked, the corresponding busbars are docked first. Then the driving mechanism is used to drive the connection cover 1 2 forward, and the two guide plates 7 are driven forward synchronously. The inclined surface 23 slides relative to the movable plate 11, and the movable plate 11 and the pressing plate 16 can be driven to move synchronously in the direction close to the busbar. At this time, the spring 18 is gradually compressed. At the same time, the connecting column 9 and the positioning head 10 move synchronously. When the pressing plate 16 is pressed against the busbar, the positioning head 10 is pressed against the positioning groove 21 of the positioning plate 20, which improves the stability of the connected busbars and has a high degree of fit. It replaces the traditional bolt connection method with high efficiency, and also realizes the docking of the connection cover 1 2 and the connection cover 2 3, that is, the two bus ducts are conveniently connected, and the connecting protrusion 13 is pressed against the sealing groove 22, which effectively prevents external dust and water stains from invading the connected busbars, achieving a good protection purpose and avoiding the hidden danger of short circuit.

[0021] When the two bus ducts need to be separated, the driving mechanism is used to drive the connection cover 1 2 to move back, and the guide plate 7 is driven to move back synchronously. The guide plate 7 is separated from the movable plate 11, and the compressed spring 18 drives the movable plate 11 to move back, so that the pressing plate 16 is separated from the busbar, thereby loosening the connected busbars, and the positioning head 10 is separated from the positioning groove 21, so that the connection cover 1 2 and the connection cover 2 3 are separated, so as to achieve the purpose of rapid separation with high efficiency.

[0022] The driving mechanism includes a stud 4, a guide seat 5, and a rotating head 6. The guide seat 5 is fixed to the top of the bus duct body 1, and the guide seat 5 is used to guide the stud 4.

The rotating head 6 drives the stud 4 to rotate, and the stud 4 cooperates with the thread groove to drive the connection cover 2 to move back and forth.

[0023] The stud 4 passes through the guide seat 5 , and the stud 4 is rotatably connected to the guide seat 5 , thereby improving the rotation stability of the stud 4 .

[0024] The clamping mechanism also includes a connecting plate 15, a guide post 17, and a guide groove 19. The guide groove 19 is used to guide the connecting plate 15. The guide post 17 runs through the connecting plate 15. The end of the connecting plate 15 is connected to the moving plate 11. When the moving plate 11 moves, the connecting plate 15 is synchronously driven to slide on the guide groove 19. With the use of the guide post 17, the moving plate 11 and the pressing plate 16 move stably to avoid skewing and deviation.

[0025] The guide groove 19 is arranged at the end of the bus duct body 1, the guide column 17 is connected to the guide groove 19, the spring 18 is sleeved on the guide column 17, and the two ends of the spring 18 are connected to the connecting plate 15 and the bus duct body 1, and the connecting plate 15 is slidably connected to the guide groove 19.

[0026] The connection mechanism includes a connection column 9, a positioning head 10, and an inclined surface 14. The two ends of the connection column 9 are connected to the moving plate 11 and the positioning head 10. The inclined surface 14 is arranged on the positioning head 10. A positioning plate 20 is connected inside the connection cover 23. The positioning plate 20 is provided with a positioning groove 21, and the positioning groove 21 matches the positioning head 10. When the moving plate 11 moves forward, the connection column 9 and the positioning head 10 are synchronously driven to move. The inclined surface 14 and the ends of the positioning groove 21 first slide toward each other, and a certain pulling force is applied to the positioning plate 20, so that the connection cover 12 and the connection cover 23 are firmly and tightly connected, thereby improving the stability of the connection between the two bus ducts.

[0027] The end of the connection cover 1 2 is connected with a connection protrusion 13, and the connection protrusion 13 is provided with a sealing surface 12, and the connection protrusion 13 matches the sealing groove 22 provided at the end of the connection cover 2 3. The connection protrusion 13 is connected to the sealing groove 22, which improves the sealing performance of the connection between the connection cover 1 2 and the connection cover 2 3, and prevents the invasion of dust and water stains from the outside. The connection protrusion 13 is made of high-strength steel material to avoid the hidden danger of bending deformation at the connection, so that the connection strength of the two bus ducts is high and the use is safe and reliable.

[0028] The bus duct body 1 is provided with transverse grooves 8 on both sides, the guide plate 7 is slidably connected to the transverse grooves 8, and the guide plate 7 is fixedly connected to the connection cover 1 2. When the connection cover 1 2 moves, the guide plate 7 slides in the transverse grooves 8, improving the stability of the movement of the connection cover 1 2 and playing a good guiding role. The end of the guide plate 7 is provided with an inclined surface 23, which is a smooth surface and can reduce the contact friction with the moving plate 11.

[0029] A method for connecting a bus duct with a stable connection comprises the following steps: Step 1: The busbars of the two bus ducts are connected to each other, and the rotating head 6 drives the stud 4 to rotate, which can drive the connection cover 2 to move forward, and synchronously drive the guide plate 7 to move forward. The guide plate 7 applies a thrust to the moving plate 11, so that the moving plate 11 and the pressing plate 16 move synchronously toward the busbar; Step 2: The movement of the moving plate 11 can synchronously drive the connecting column 9 and the positioning head 10 to move, and the second inclined surface 23 and the moving plate 11 slide relative to each other; Step three: When the pressing plate 16 is pressed against the busbar, the positioning head 10 is pressed against the positioning groove 21 of the positioning plate 20, which can not only improve the stability of the connected busbars and achieve a high degree of fit to achieve the locking purpose, but also replace the traditional bolt connection, and at the same time realize the docking of the connecting cover 1 2 and the connecting cover 2 3, that is, the two bus ducts are conveniently connected, and the connecting protrusion 13 is pressed against the sealing groove 22, which effectively prevents external dust and water stains from invading the connected busbars, thereby achieving a good protection purpose.
