Description

Technical Field

[0001] This utility model relates to the field of copper-aluminum busbar technology, and in particular to a compression-fit copper-aluminum busbar. Background Technology

[0002] When installing copper-aluminum busbars at different heights in the same location, L-shaped copper-aluminum busbars are usually required for connection. Existing copper-aluminum busbars have a flat structure, and the clamping force during fastening cannot form an inward concentrated force, resulting in relatively poor clamping strength. When existing copper-aluminum busbars are fastened with bolts, the sealing of the fastening position is not guaranteed, and the stability of the contact and fit of different components at the fastening position is relatively poor, resulting in relatively low load-bearing capacity during later use. Utility Model Content

[0003] The purpose of this utility model is to provide a compression-fitting copper-aluminum busbar that can meet the needs of installing copper-aluminum busbar products of different heights and achieve a stable and secure connection. The fastening position is reinforced with a compression structure to ensure higher fastening strength at different positions. The compression structure is locked in place with a nut during fastening, resulting in stronger load-bearing capacity, higher tensile strength, and greater durability. This design can meet the needs of installation positions with high load-bearing capacity requirements.

The lower center of the column has a main body fastening connection hole that passes through the upper part of the whole. The lower left side of the main body and the clamping plate has a cylindrical positioning fastening connection column. The outer cylindrical surface of the positioning fastening connection column has a fastening connection locking thread groove. The front and rear right sides of the main body and the clamping plate have clamping and stabilizing plates that are processed by pressing. The clamping and stabilizing plates are inclined structures with a downward tilt. The outer end face of the clamping and stabilizing plate in the front and rear direction coincides with the outer end face of the corresponding position in the front and rear direction of the main body and the clamping plate.

[0020] like Figures 1 to 7As shown, a compression-fitting copper-aluminum busbar includes a horizontally oriented main body compression plate 1. An integrally formed transition support plate 2 is provided on the upper left side of the main body compression plate 1, allowing for different height differences between the left and right sides of the mating structure, thus meeting the connection requirements of mating structures with different heights. An integrally formed horizontally oriented left-side fastening connection plate 3 is provided on the upper end of the transition support plate 2. The width of the left side of the integral fastening connection plate 3 is greater than the width on the right side, allowing for embedded assembly according to the required installation position, resulting in better stability during mating and a reliable anti-loosening effect, effectively reinforcing the connection. The width of the integral fastening connection plate 3 in the front-back direction is the same as the width of the main body compression plate 1 in the front-back direction, ensuring better flatness of the outer side of the overall structure, reducing space occupation during use, and facilitating installation and mating operations. A reinforcing and sealing mating post 4 is provided at the lower end of the integral fastening connection plate 3, effectively reinforcing the mating structure when fastening at this position. The reinforced sealing mating column 4 has a main body fastening connection hole 5 at its lower center, which extends through the upper part of the entire structure, allowing it to be fastened together with existing fastening bolt-type accessories. A cylindrical positioning fastening connection column 6 is located on the lower left side of the main body mating pressure plate 1. The outer cylindrical surface of the positioning fastening connection column 6 has a fastening connection locking thread groove, allowing it to be fastened together with a fastening nut. The front and rear right sides of the main body mating pressure plate 1 are respectively provided with pressing-fit stabilizing plates 7, which are inclined downwards, allowing their lower ends to be pressed together with the mating structure. The outer end face of the clamping and stabilizing plate 7 in the front-rear direction coincides with the outer end face of the corresponding position of the main clamping plate 1 in the front-rear direction, ensuring better flatness of the mating position, higher structural strength, and stronger load-bearing capacity during later use. This structure is set as a core innovation during production, rather than a conventional direct bending process. Conventional bending methods cannot guarantee the flatness of the outer end face after processing, which will affect the assembly accuracy and mating load-bearing strength during installation. This structure is processed with a pressing mold during production and also requires heat treatment. The structural stability is better guaranteed, ensuring the clamping load-bearing capacity during mating installation. It adopts a brand-new structural design, which can meet the installation and fastening of copper and aluminum busbar products of different heights during use. The fastening position is equipped with a reinforcement structure and a clamping structure, which can ensure higher fastening strength at different positions. The clamping structure position is locked with a nut during fastening, which has stronger load-bearing capacity during fastening, higher tensile strength during later use, and greater durability during use, meeting the needs of installation positions with high load-bearing strength requirements.

[0021] Preferably, the left side of the integral fastening connecting plate 3 is a cylindrical structure, and the right side of the integral fastening connecting plate 3 is an inclined slope structure in the front-back direction. When assembled, it can be embedded and matched with the combination hole at the matching position, ensuring better tightness and stability during the matching.

[0022] Preferably, the lower outer edge of the reinforced sealing mating column 4 is provided with a mating guide cone surface for easy installation, making the assembly operation more convenient and the mating efficiency higher.

[0023] Preferably, the thickness of the integral fastening connecting plate 3 is the same as the thickness of the main body mating clamping plate 1, which makes the overall structure have lower processing costs and higher production efficiency during production, and can be processed quickly using the same flat material.

[0024] Preferably, the positioning and fastening connecting column 6 is manufactured by riveting, which makes the structure more convenient to produce and easier to process.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
