[0019] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] like Figure 1-3 As shown, the utility model is a copper busbar with high conductivity, including a copper busbar body 1, in which a plurality of hollow cavities 2 are arranged, and conductive support plates 3 are arranged between the hollow cavities 2, and the conductive support plates 3 are arranged through both ends of the copper busbar body 1.

[0023] By setting the hollow cavity 2, the amount of copper material used in processing the copper busbar can be effectively reduced, thereby reducing production costs and reducing burdens and gains.

[0024] In addition, the provision of the conductive support plate 3 can effectively support the copper busbar body 1, and can effectively avoid deformation of the copper busbar body 1 due to lack of internal support when the copper busbar body 1 is installed or bent, thereby affecting the normal use of the product.

[0025] At the same time, while playing a supporting role, it can also increase the conductive area of ​​the entire copper busbar body 1. The surface conductivity of the traditional solid copper busbar can only be conducted through the outer surface, and the surface conductivity speed is faster.

[0026] In this solution, the hollow portion is designed to cooperate with the conductive support plate 3, so that the surface of the hollow portion and the surface of the conductive support plate 3 can both be conductive, thereby improving the overall conductive speed and efficiency.

[0027] The copper bar body 1 comprises an upper copper bar body 11 and a lower copper bar body 12 . Both sides of the upper copper bar body 11 and the lower copper bar body 12 are provided with mounting parts 13 , and the upper copper bar body 11 and the lower copper bar body 12 are fixedly connected via the mounting parts 13 .

[0028] The arrangement of the copper busbar upper body 11 and the copper busbar lower body 12 can make processing more convenient and reduce production difficulty.

[0029] An upper supporting ridge 111 is disposed on the lower surface of the copper busbar upper body 11 , a lower supporting ridge 121 is disposed on the upper surface of the copper busbar lower body 12 , and the conductive support plate 3 is composed of the upper supporting ridge 111 and the lower supporting ridge 121 .

[0030] The upper supporting ridges 111 and the lower supporting ridges 121 cooperate with each other to effectively support the upper copper bar body 11 and the lower copper bar body 12 .

[0031] Obviously, the structural design of supporting the conductive support plate 3 composed of the upper supporting ridge 111 and the lower supporting ridge 121 can be replaced by other structural methods. For example, the upper body 11 and the lower body 12 of the copper bar are both provided with mounting positions that cooperate with the conductive support plate 3. The conductive support plate 3 is designed as an independent part. When installing, it is only necessary to set the conductive support plate 3 in the mounting position. The conductive support plate 3 can also be integrally formed with the upper body 11 or the lower body 12 of the copper bar, or part of the conductive support plate 3 is integrally formed with the upper body 11 of the copper bar, and the other part is integrally formed with the lower body 12 of the copper bar. The effect of the above scheme can also be achieved.

[0032] Hollow grooves 21 are provided on the sides of the upper supporting convex strip 111 and the lower supporting convex strip 121 , and the hollow cavity 2 is composed of the hollow grooves 21 of the copper bar upper body 11 and the copper bar lower body 12 .

[0033] The mounting portion 13 of the copper bar upper body 11 is an upper connecting platform 112 disposed on the copper bar upper body 11 , and the mounting portion 13 of the copper bar lower body 12 is a lower connecting platform 122 disposed on the copper bar lower body 12 . The upper connecting platform 112 and the lower connecting platform 122 are soldered with tin wire.

[0034] The cooperation between the upper connecting platform 112 and the lower connecting platform 122 can reduce the processing difficulty, and the tin wire welding can ensure that the copper bar upper body 11 and the copper bar lower body 12 are still a whole in terms of conductivity.

[0035] Obviously, the connection structure mode of the upper connecting platform 112 and the lower connecting platform 122 by tin wire welding can also be replaced by other structural designs. For example, the mounting portion 13 of the copper busbar upper body 11 is a snap-fitting protrusion arranged on the copper busbar upper body 11, and the mounting portion 13 of the copper busbar lower body 12 is a snap-fitting groove arranged on the copper busbar lower body 12. The snap-fitting groove can be snap-fitted with the snap-fitting protrusion, which can also achieve the effect of the above-mentioned scheme.

[0036] The copper bar upper body 11 and the copper bar lower body 12 are symmetrical structures, which can make processing more convenient and share the production mold, further improving the effect of reducing load and gain.

[0037] A graphene coating is provided in the hollow cavity 2 , and the graphene coating can further improve the conductivity of the copper busbar body 1 .

[0038] The number of the hollow parts is five, the number of the conductive support plates 3 is four, the five hollow parts are symmetrically arranged, and the area of ​​the hollow parts gradually increases from the outside to the inside.

[0039] Obviously, the number of hollow parts is five, the number of conductive support plates 3 is four, the five hollow parts are arranged symmetrically, and the structural design of the area of ​​the hollow parts gradually increases from the outside to the inside is not limited to the above scheme. The number and area of ​​the hollow parts are not limited, and can be adjusted according to the size of different copper busbar bodies 1, and the effect of the above scheme can also be achieved.

[0040] From the above, it can be seen that the beneficial effects of the utility model are: the use of its mechanism can effectively solve the problem of high processing cost of the solid structure of the constant copper busbar in the prior art. By using this product structure and the setting of the hollow part, the cost of copper materials can be effectively reduced, and the stability of the internal structure can be ensured by the conductive support plate 3 to avoid serious deformation that affects the normal use of the product, and the side of the conductive support plate 3 can also increase the conductive area of ​​the copper busbar surface, improve the conductive efficiency, and help to improve the competitiveness of the enterprise.

[0041] The specific implementation methods described above are preferred implementation methods of the present utility model, and are not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation methods. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
