Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bus ducts, and particularly relates to a rivetless assembly bus duct. Background Technique
[0002] The compact bus duct is a component used in the power distribution system. It is usually made of insulating materials and is used to install, support and protect electrical equipment. This type of bus duct is designed compactly and can accommodate multiple electrical busbars in a limited space, providing good insulation and safety protection.
[0003] In the process of using the existing compact bus duct, the common method is to pre-assemble the busbars and then press the busbars on the fixing tooling, and operate one by one according to the predetermined riveting point process with a riveting gun. This riveting process takes a long time, has low efficiency, has many riveting points, and at the same time, there is no good quality control means for the riveting strength, which is easy to cause problems such as empty riveting, missing riveting, and multiple riveting, resulting in low product quality. Content of the Utility Model
[0004] The purpose of the utility model is to provide a rivetless assembly bus duct to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A rivetless assembly bus duct, comprising:
[0007] A right side plate and a left side plate;
[0008] On the upper and lower parts of the opposite surfaces of the right side plate and the left side plate, deformable hooks are fixedly connected, and on one side of the inner walls of the four deformable hooks, limiting grooves are provided;
[0009] An upper cover is arranged between the upper parts of the right side plate and the left side plate, and a lower cover is arranged between the lower parts of the right side plate and the left side plate. On both sides of one end of the upper cover and the lower cover, limiting blocks are fixedly connected, and limiting protrusions are fixedly connected to one ends of the limiting blocks;
[0010] Four conductors are inserted and connected together among the right side plate, the left side plate, the upper cover and the lower cover.
[0011] Preferably, the size of the limiting groove is the same as the size of the limiting protrusion.
[0012] Preferably, the other ends of the upper cover and the lower cover are closely attached to the right side plate and the left side plate.
[0013] Preferably, the periphery of the conductor is in close contact with the right side plate, the left side plate, the upper cover and the lower cover.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] (1) By providing a right side plate, a left side plate, an upper cover, a lower cover and a deformable hook, when assembling, applying a certain external force to press the deformable hook. As the deformable hook deforms, the limiting groove engages with the limiting protrusion, so that the upper cover or the lower cover is fixed, achieving the purpose of fixing the overall structure of the busbar. The device is set as a non-rivet assembly structure, and the assembly of the device is realized through deformation. The structure is compact and beautiful, has a good streamline, and high mechanical strength. The riveting efficiency can be several times that of the automatic assembly line, making the production efficiency of the device high. At the same time, it saves the cost of rivets and the investment in riveting guns.
[0016] (2) By closely fitting the conductor with the right side plate, the left side plate, the upper cover and the lower cover, the heat generated when the busbar is energized and operated is exchanged with the right side plate and the left side plate, achieving a better heat dissipation purpose. At the same time, the busbar waterproofing can achieve external protection, which is more stable and durable than internal protection, and does not affect the waterproof surface due to riveting deformation, and can achieve a higher IP protection level.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1:
[0024] Please refer to Figure 1 - Figure 4 as shown, a non-rivet assembly busbar chute, comprising:
[0025] Right side plate 1 and left side plate 2;
[0026] On the upper and lower parts of the opposite faces of the right side plate 1 and the left side plate 2, deformable hooks 6 are fixedly connected, and a limiting groove 7 is formed on one side of the inner walls of the four deformable hooks 6;
[0027] An upper cover 4 is arranged between the upper parts of the right side plate 1 and the left side plate 2, and a lower cover 5 is arranged between the lower parts of the right side plate 1 and the left side plate 2. On both sides of one end of the upper cover 4 and the lower cover 5, limiting blocks 8 are fixedly connected, and limiting convex blocks 9 are fixedly connected to one ends of the limiting blocks 8;
[0028] Four conductors 3 are inserted and connected among the right side plate 1, the left side plate 2, the upper cover 4 and the lower cover 5 together.
[0029] From Figure 2 it can be seen that the size of the limiting groove 7 is the same as that of the limiting convex block 9.
[0030] As can be seen from the above, a deformable hook 6 is arranged at each of the upper and lower parts of the right side plate 1 and the left side plate 2. Applying a certain external force to press the deformable hook 6 makes the deformable hook 6 perform an arc movement. As the deformable hook 6 deforms, the limiting groove 7 inside it will accurately engage with the limiting convex block 9 protruding on the limiting block 8, thereby realizing the effective limiting of the limiting block 8, fixing the upper cover 4 or the lower cover 5, and achieving the purpose of fixing the overall structure of the busbar.
[0031] Embodiment 2:
[0032] Referring to Figure 1 and Figure 4 as shown, the other ends of the upper cover 4 and the lower cover 5 are closely attached to the right side plate 1 and the left side plate 2; the peripheries of the conductors 3 are in close contact with the right side plate 1, the left side plate 2, the upper cover 4 and the lower cover 5.
[0033] As can be seen from the above, the peripheries of the conductors 3 located in the middle of the right side plate 1, the left side plate 2, the upper cover 4 and the lower cover 5 are all in close contact with them. When the busbar is energized and operates, the heat generated is exchanged with the right side plate 1 and the left side plate 2, achieving a better heat dissipation purpose.
[0034] Working principle: By utilizing the good mechanical strength and ductility of aluminum alloy profiles, the device housing is designed as a right side plate 1, a left side plate 2, an upper cover 4, a lower cover 5, and deformable profiles for snap connection. During assembly, a certain external force is applied to press the deformable hook 6, causing the deformable hook 6 to move in an arc. As the deformable hook 6 deforms, the limit groove 7 engages with the limit protrusion 9, fixing the upper cover 4 or the lower cover 5, thereby achieving the purpose of fixing the overall structure of the busbar. At the same time, the conductor 3 located in the middle of the busbar groove is in close contact with the housing all around. When the busbar is energized and operating, the heat generated is exchanged with the right side plate 1 and the left side plate 2. There is no rivet assembly structure, and the assembly of the device is achieved through deformation. The structure is compact and beautiful, with a good streamline and high mechanical strength.
