The upper and lower covers and the left and right side panels are fastened with bolts or riveted together with piercing rivets to surround the conductors.

[0004] The conventional method for using existing bus ducts is to pre-assemble the busbars, then press the busbars with cylinders from two or four directions on a fixed fixture, and then rivet them point by point according to the process positioning requirements of the riveting points using a rivet gun with or without rivets. This riveting process is time-consuming, inefficient, and involves many riveting points. There is no good quality control method for the riveting strength of each point, which can easily result in empty rivets, missed rivets, and excessive rivets, making it difficult to ensure the structural strength of the busbar and the consistency of the product.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0034] As attached Figure 1To the attached Figure 3 As shown:

[0035] Embodiment 1: This embodiment provides a two-piece rivetless assembly high-efficiency heat dissipation bus duct, comprising:

[0036] Two housings 1, and a connecting mechanism 2 and a limiting mechanism 3 provided at the junction of the two housings 1;

[0037] The housing 1 includes a vertical plate 101 and a horizontal plate 102, and the vertical plate 101 is vertically connected to the horizontal plate 102;

[0038] The connecting mechanism 2 includes a deformable hook 201 provided on one of the housings 1 and a fixed hook 202 provided on the other housing 1. The deformable hook and the fixed hook 202 are interlocked.

[0039] The limiting mechanism 3 includes a second deformable hook 302 , which is located on the housing 1 on one side of the fixed hook 202 . The second deformable hook 302 is mirror-imaged to the first deformable hook 201 , and a fixed plate 301 is provided between the second deformable hook 302 and the housing 1 .

[0040] The shell 1 is made of an integrated vertical plate 101 and a horizontal plate 102. Only two pieces of shell 1 are needed for assembly, so that the bus duct has a better degree of integration after final assembly than the four-piece type, has a better thermal conductivity than the four-piece type, and has a more balanced heat dissipation, thereby improving the overall heat dissipation efficiency.

[0041] The main structure of the device is made of aluminum alloy profiles.

[0042] Specifically, a notch 4 is provided between the vertical plate 101 and the horizontal plate 102 .

[0043] The provision of the notch 4 facilitates the installation of the heat conducting plate 6 during assembly. After the heat conducting plate 6 contacts the conductor 5, a portion of the heat conducting plate 6 is inserted into the notch 4 to increase the overlapping area between the heat conducting plate 6 and the housing 1, thereby increasing the heat exchange effect. The applicable situations are as follows:

[0044] Double T-shaped heat conducting plate 6 (as attached Figure 6 As shown), double C-type heat conduction plates 6 (left and right centered setting, left and right symmetrical phase-separated setting, left and right asymmetric phase-separated setting), L-type heat conduction plates 6 (inner-wrapped setting, outer-wrapped setting), Z-type heat conduction plates 6 (outer-wrapped setting), etc.

[0045] Specifically, a slot 203 is provided at the bending portion of the deformable hook 1 201 , a clamping block 204 is provided on the inner side of the deformable hook 1 201 , and a stopper 205 is provided on the inner side of the fixed hook 202 .

[0046] By providing a clamping groove 203 at the bend of the deformable hook 1 201, the thickness of the bend is smaller than that at other positions, thereby reducing the material strength at the bend. When a person applies external force to the deformable hook 1 201, the deformable hook 1 201 is bent and deformed at the clamping groove 203 until it is buckled onto the fixed hook 202, completing the connection and assembly of the two housings 1. No riveting is required, the structure is compact and beautiful, the strength is high, and the investment in equipment such as rivet guns is reduced while improving processing efficiency, and a protection level of IP66 or above can be achieved.

[0047] During the bending process of the deformable hook 201, the block 204 will contact the stopper 205, and the stopper 205 will block the block 204. At this time, continue to apply pressure to the deformable hook 201, and the block 204 can pass over the stopper 205 under the elastic action of the material until the deformable hook 201 rotates 90° and engages with the fixed hook 202. At this time, the block 204 is located at the lower part of the stopper 205, and is tightly fitted with the stopper 205 under its own elastic action, thereby improving stability.

[0048] Specifically, the deformable hook 1 201 , the deformable hook 2 302 and the fixed hook 202 are all arranged in an L shape.

[0049] The deformable hook 201 and the fixed hook 202 of this embodiment are respectively located at the upper left corner and the lower right corner of the shell 1. The two shells 1 have the same structure and are rotationally symmetrical when in use, so that the deformable hook 201 of one shell 1 contacts the fixed hook 202 of the other shell 1.

[0050] As can be seen from the above, after the two shells 1 are buckled onto the outer periphery of the conductor 5, the deformable hook 201 is brought into contact with the fixed hook 202, and an external force is used to push the deformable hook 201 to rotate and deform it until it is stuck in the fixed hook 202. The connection of the two shells 1 is completed by the mortise and tenon relationship, without the need for rivets or other structural fixation. Then, the deformable hook 202 is pushed by an external force to rotate and deform it in the direction of the fixed hook 202 until its outer side surface contacts the outer side surface of the deformable hook 1 201. The deformable hook 201 can be blocked by the deformable hook 202 to prevent it from easily rotating and deforming in the initial direction due to external force and becoming loose, thereby improving stability. Due to the L-shaped setting of the deformable hook 202, a square space is formed in the middle of the deformable hook 202 after it is rotated. At this time, a reinforcement rod or the like can be passed through the space to reinforce the deformable hook 202, further improving the stability of the deformable hook 1 201, or structures such as sensor wires and water cooling pipes can be passed through to increase the expandable space of the device and facilitate personnel use.

[0051] As attached Figure 4 As shown:

[0052] Embodiment two: this embodiment is basically the same as the previous embodiment, the difference is that the deformed hooks 201 are all arranged on one shell 1, and the fixed hooks 202 are all arranged on another shell 1, and the two shells 1 are arranged in a C-shaped non-rotational symmetry.

[0053] As shown in the accompanying drawings Figure 5 and the accompanying drawings Figure 6 :

[0054] Embodiment two: this embodiment provides an assembly method of a two-piece rivet-free assembly high-efficiency heat dissipation bus duct, comprising:

[0055] S1, the two shells 1 are assembled to the conductor 5 on both sides after being rotationally symmetrical, so that the two vertical plates 101 and the two horizontal plates 102 are in contact with the four sides of the conductor 5 respectively;

[0056] S2, at the same time, pressure is applied to the four sides of the shell 1 until the conductor 5 is tightly attached to the inner wall of the shell 1;

[0057] S3, a pushing force is applied to the deformed hook 201, which is rotated and deformed around the clamping groove 203 as the axis until it is buckled with the corresponding fixed hook 202, completing the connection of the two shells 1;

[0058] S4, a pushing force is applied to the deformed hook 302, which is rotated and deformed around the intersection of the fixed plate 301 and the deformed hook 302 as the axis until its outer surface is in contact with the outer surface of the deformed hook 201, completing the position limitation of the deformed hook 201.
