[0036] Example

[0037] Figure 1-6 The embodiment of the present application shown provides a high-precision intensive bus duct without riveting. In practical applications, the intensive bus duct is usually installed in multiple combinations in a low-voltage power transmission trunk line project for efficient transmission of electric energy. It includes: a housing 1 and a conductor 2 penetrating the housing 1;

[0038] See also Figure 2-Figure 4 Among them, the shell 1 includes: two cover plates 11 and two side plates 12; the two cover plates 11 in the above technical solution are parallel to each other, the two side plates 12 are parallel to each other, and the two cover plates 11 are respectively connected to the two ends of the side plates 12, so as to form a shell 1 with a rectangular structure, and the interior of the shell 1 is a space capable of accommodating the conductor 2; the cover plate 11 and the side plate 12 are preferably made of 6063 drawn high-precision aluminum alloy profiles, which have the advantages of high strength, light weight, and good conductivity, and can ensure the use strength of the shell 1.

[0039] Two ribs 13 are respectively provided on the surfaces of the two cover plates 11 close to the side plates 12 along the length direction of the conductor 2. The ribs 13 are L-shaped metal plates made of 6063 drawn high-precision aluminum alloy profiles. A card slot 131 for fixing the side plates 12 is respectively formed between the two ribs 13 on the surface of the cover plate 11 and the cover plate 11; and the opening directions of the two card slots 131 on the same cover plate 11 are opposite.

[0040] Furthermore, the side plate 12 is a U-shaped structure, which includes: a bottom plate 121 and wall plates 122 vertically connected to both sides of the bottom plate 121, the thickness of the wall plate 122 matches the opening width of the slot 131, and the wall plate 122 is snapped into the slot 131, so that the concave surface of the side plate 12 after installation is outward and the two side wall plates 122 are respectively fitted with the cover plates 11 on both sides; it can be understood that the distance between the slots 131 on the same cover plate 11 is greater than the width of the conductor 2, so that the space between the two side plates 12 after installation is sufficient to accommodate the conductor 2; in the above technical solution In the embodiment, both ends of each wall plate 122 are provided with a first mounting hole, and the cover plate 11 is provided with four second mounting holes, the sizes of the second mounting holes match the first mounting holes and correspond one to one; when the housing 1 of the riveting-free high-precision intensive bus duct is assembled by adopting the above technical scheme, after the wall plate 122 is clamped in the clamping groove 131, the position of the wall plate 122 is adjusted to align the first mounting hole with the second mounting hole, so as to realize the positioning between the side plate 12 and the cover plate 11, thereby ensuring that the end face of the housing 1 is flush, and providing a high-precision mounting surface for installing adjacent bus ducts; then, at the first mounting hole, the second mounting hole is aligned with the second mounting hole, and the second mounting hole is aligned with the second mounting hole, so as to realize the positioning between the side plate 12 and the cover plate 11, and then ensure that the end face of the housing 1 is flush, and provide a high-precision mounting surface for installing adjacent bus ducts; then, at the first mounting hole, the second mounting hole is aligned with the second mounting hole, and ... The bolts 14 are passed through the first and second mounting holes to firmly connect the side plate 12 and the cover plate 11. As a preferred embodiment of the present application, the bolts 14 passed through the first and second mounting holes can be hexagonal flange bolts. The hexagonal flange bolts have a large support area to stress area ratio, can withstand high preload, have good relaxation performance, and have high tensile and shear strength. They are suitable for connection environments with high tensile and shear forces between the cover plate 11 and the side plate 12, and their convenient installation further reduces the assembly cost of the intensive bus duct. The slots 131 and the bolts 132 are used. 4. The surface of each wall panel 122 is only provided with two bolts 14, and the rest are fixed by being clamped in the clamping groove 131. Compared with the connection method using multiple rivets or multiple arranged bolts in the prior art, it not only avoids the problems of oblique nails, biting nails, depressions, misalignment, etc. that may be caused by manual riveting, but also can greatly optimize the number of bolts while ensuring the reliability of the connection and improving the assembly efficiency; and a locking structure is formed between the cover plate 11 and the side plate 12, so that the surface of the cover plate 11 and the side plate 12 is smooth and simple, which improves the overall aesthetics of the bus duct.

[0041] As a preferred embodiment of the present application, a plurality of heat dissipation strips are provided on the outer side of the base plate 121 along the length direction of the outer shell 1. The design of the heat dissipation strips makes the outer surface of the base plate 121 wavy, thereby increasing the heat dissipation area of ​​the base plate 121 and improving the heat dissipation efficiency of the bus duct.

[0042] See also Figure 4 and Figure 5, further, the conductor 2 is composed of a plurality of conductive bars 21 arranged side by side, the conductive bars 21 are rectangular bars or round-edge bars, and preferably precision-drawn high-purity low-resistance copper bars are used; the surface of any conductive bar 21 is covered with an insulating film 22, and as a preferred embodiment of the present application, the insulating film 22 is a polyurethane insulating film, which can effectively prevent the occurrence of discharge during the use of the bus duct to ensure safety and electrical insulation;

[0043] Furthermore, a silicone rubber pad 23 is provided between the conductor 2 and the side plate 12, and the shape and size of the silicone rubber pad 23 are adapted to the bottom plate 121; when assembling the bus duct, the two side plates 12 are first fixed on a single cover plate 11, and then the conductor 2 is placed between the two side plates 12. At this time, there is a certain gap between the conductor 2 and the side plate 12, which will cause the conductor 2 to move in the housing 1. In particular, when installing the second cover plate 11, the cover plate 11 must be inserted into the card slot 131 from the end face direction of the side plate 12. During the movement of the cover plate 11, friction occurs with the conductor 2, which easily causes the conductor 2 to deviate, resulting in a decrease in assembly accuracy; the design of the silicone rubber pad 23 fills the gap between the conductor 2 and the side plate 12, and can provide a certain clamping force, so that the conductor 2 is firmly clamped between the two side plates 12, effectively avoiding the deviation of the conductor 2 during the assembly process, and ensuring the assembly accuracy of the bus duct; at the same time, the silicone rubber pad 23 has a certain flexibility, which can play a certain protective role on the insulating film 22 on the surface of the conductive bar 21.

[0044] The housing 1 in the above technical solution is suitable for installing conductors 2 of three-phase four-wire wiring mode and conductors 2 of three-phase five-wire wiring mode. As one embodiment of the present application, when three-phase four-wire system is adopted, the conductor 2 includes four conductive bars 21, and silicone rubber pads 23 are placed on both sides of the conductor 2. As another embodiment of the present application, when three-phase five-wire system is adopted, the conductor 2 includes five conductive bars 21, and silicone rubber pads 23 are placed on one side of the conductor 2. With this technical method, the thickness of the silicone rubber pad 23 after assembly and compression matches the thickness of the conductive bar 21. By replacing the single-side silicone rubber pad 23 in the three-phase four-wire system with an extra conductive bar 21 in the three-phase five-wire wiring mode, the thickness of the conductor 2 plus the silicone rubber pad 23 in the two wiring modes can be made close. In this technical solution, the same housing 1 can be suitable for accommodating conductors 2 of various wiring modes without changing the size according to different wiring modes, thereby realizing the standardization of product parts production.

[0045] See also Figure 6Furthermore, a joint assembly 3 is also connected to the cover plate 11, and the joint assembly 3 is used to connect adjacent dense bus ducts, and includes: a terminal seat 31 and a joint side plate 32; wherein the terminal seat 31 is a rectangular precision die-casting, and two third mounting holes are respectively provided on its upper and lower surfaces, and a fourth mounting hole for fixing the joint side plate 32 is provided on its side surface; the hole spacing between the two third mounting holes matches the two second mounting holes in the width direction of the cover plate 11; the terminal seat 31 is close to the edge of the cover plate 11, and the first mounting hole, the second mounting hole, and the third mounting hole are made to correspond, and the terminal seat 31 is fastened to the cover plate 11 by passing the bolts 14 through the first mounting hole, the second mounting hole, and the third mounting hole.

[0046] The joint side plate 32 includes an L-shaped metal plate. Two joint side plates 32 are fixed on the side of the terminal seat 31 and surround the conductor 2 on the inner side thereof. The joint assembly 3 in the above technical solution connects adjacent dense bus ducts and is a connection accessory that enables the dense bus ducts to achieve a dust-tight effect.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
