[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0028] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0030] Reference example Figures 1 to 4 A stable air-type bus duct includes a base plate 1, a cover plate 2, and a conductor 3. The base plate 1 and the cover plate 2 are provided with at least two insulating bases 4. The insulating bases 4 are provided with a plurality of first grooves 41 for accommodating the conductors 3. Spring pieces 5 are provided on both sides of the first grooves 41 and act on the conductors 3. A partition 6 is provided between the insulating bases 4 and is arranged between the conductors 3. Side plates 7 are provided on both sides of the base and the cover plate 2. The side plates 7 are provided with a plurality of evenly spaced heat dissipation fins 71 from top to bottom. A fastening assembly 8 is provided between the base and the cover plate 2 to form a clamping force between the upper and lower insulating bases 4 to clamp the conductors 3.

[0031] It is worth mentioning that the first groove 41 is provided with a second groove 42 on both sides thereof for accommodating the spring piece 5 , and the first groove 41 is provided with a fixing groove 43 on both sides thereof, and the fixing groove 43 cooperates with the fixing portion 52 ;

[0032] It is worth mentioning that an inclined guide surface 51 is provided at the entrance of the spring sheet 5, and fixing parts 52 are provided on both sides of the spring sheet 5. The fixing parts 52 are provided with inclined blocks 53 and abut against the side walls of the fixing groove 43. When the conductor 3 abuts the guide surface 51 and applies downward pressure to the conductor 3, the spring sheet 5 expands to both sides to accommodate the conductor 3 to enter between the spring sheet 5 and the first groove 41. The fixing part 52 is connected and fixed to the fixing groove 43 in an interference fit manner through the inclined blocks 53. The spring sheet 5 applies a force to the conductor 3 to enhance the connection stability between the conductor 3 and the first groove 41. When the air-type bus duct is affected by vibration, the spring sheet 5 absorbs the energy conducted from the conductor 3 and buffers it, thereby preventing the conductor 3 from being displaced due to vibration. At the same time, the spring sheet 5 also compensates for the tolerance caused by the manufacturing and processing of the conductor 3 and the first groove 41, ensuring that the conductor 3 is in the middle position of the first groove 41.

[0033] It is worth mentioning that the side panels 7 are provided with extensions 72 on both sides. The extensions 72 are higher than the height of the heat dissipation fins 71. The back panel of the side panels 7 is provided with a first connecting portion 73, which abuts the bottom panel 1 and the cover panel 2. The extensions 72 protect the heat dissipation fins 71 and prevent dust from falling onto the surface of the heat dissipation fins 71. When a large current passes through the conductor 3, the temperature inside the air bus duct rises, and the temperature rises together with the side panels 7. After heat exchange between the heat dissipation fins 71 and the external air, the temperature inside the air bus duct is reduced.

[0034] It is worth mentioning that the insulating base 4 has second connecting portions 44 on both sides thereof, which abut against the first connecting portion 73. The sidewall of the insulating base 4 has a plurality of threaded holes 45. The second connecting portions 44 are used in conjunction with the bolts 81, and the threaded holes 45 are used in conjunction with the fastening screws 62.

[0035] It is worth mentioning that the fastening assembly 8 includes a bolt 81 and a nut 82 . The bolt 81 passes through the cover plate 2 , the first connecting portion 73 , the second connecting portion 44 , and the base plate 1 in sequence. The nut 82 is threadedly connected to the bolt 81 and abuts against the base plate 1 .

[0036] It is worth mentioning that the bottom of the partition 6 is provided with a third connecting portion 61, which abuts the side wall of the insulating base 4. The third connecting portion 61 is provided with a fastening screw 62 and is threadedly connected to the threaded hole 45. The partition 6 is fixed to the two insulating bases 4 through the third connecting portion 61. The partition 6 also serves to increase the creepage distance. The spring clip 5 cooperates with the partition 6 to limit the conductor 3 to prevent the conductor 3 from generating a large displacement due to external force, thereby ensuring that the electrical performance between the conductors 3 is not affected.

[0037] It is worth mentioning that flame retardant plates 9 are provided at the entrances at both ends of the base plate 1 and the cover plate 2 and are sleeved on the conductor 3. The flame retardant plates 9 isolate electrical fires generated externally or internally, preventing the fire from entering the cover plate 2 and the base plate 1, causing the insulating base 4 to melt.

[0038] The above design solution can enable the product to achieve the advantages of improved safety and stable clamping.

[0039] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
