[0025] like Figures 1 to 5 As shown, a novel laminated copper busbar includes: a connection structure, a mounting structure and several copper busbar bodies 300; the connection structure includes a first connecting frame 110, a second connecting frame 120 and a fixing plate 130, one end of the fixing plate 130 is connected to the first connecting frame 110, and the other end is connected to the second connecting frame 120, part of the mounting structure is arranged on the first connecting frame 110, and the other part is arranged on the second connecting frame 120; one end of each copper busbar body 300 is located on the first connecting frame 110, and the other end is located on the second connecting frame 120.

[0026] Specifically, the fixing plate 130 is a telescopic plate. The mounting structure includes a plurality of first mounting components and a plurality of second mounting components. The plurality of first mounting components are detachably mounted on the first connecting frame 110, and the plurality of second mounting components are detachably mounted on the second connecting frame 120. The first connecting frame 110 is provided with a plurality of first placement slots 111, and each first placement slot 111 is provided with two first wiring terminals 112, with the two first wiring terminals 112 being provided in correspondence. The second connecting frame 120 is provided with a plurality of second placement slots 121, and each second placement slot 121 is provided with two second wiring terminals 122, with the two second wiring terminals 122 being provided in correspondence. Each first mounting component includes a first heat conducting plate 211 and two first fixing blocks 212, one first fixing block 212 being provided on one side of the first heat conducting plate 211, and the other first fixing block 212 being provided on the other side of the first heat conducting plate 211. Each first fixing block 212 is provided with a first through-hole, and each first wiring terminal 112 partially moves through the first through-hole. Each first heat conducting plate 211 is U-shaped, and the inner sidewall of each first heat conducting plate 211 has a corrugated layer 400. Each first heat conducting plate 211 is provided with a plurality of first heat dissipation holes 500, and the plurality of first heat dissipation holes 500 are equidistantly spaced. Each second mounting assembly includes a second heat conducting plate 221 and two second fixing blocks 222, one second fixing block 222 being disposed on one side of the second heat conducting plate 221, and the other second fixing block 222 being disposed on the other side of the second heat conducting plate 221. Each second fixing block 222 is provided with a second through-hole, and each second terminal 122 partially moves through a second through-hole. Each second heat conducting plate 221 is U-shaped, and the inner sidewall of each second heat conducting plate 221 has a corrugated layer 400. Each second heat conducting plate 221 is provided with a plurality of second heat dissipation holes 600, and the plurality of second heat dissipation holes 600 are equidistantly spaced. One end of each copper busbar body 300 is connected to the first heat conducting plate 211 , and the other end is connected to the second heat conducting plate 221 .

[0027] To use this new laminated copper busbar, one end of each busbar body 300 is first inserted into the first heat conducting plate 211 and the other end into the second heat conducting plate 221. This means both ends of the busbar body 300 are in contact with the wave layer 400, and several first heat dissipation holes 500 and several second heat dissipation holes 600 extend through the wave layer 400. It's worth noting that the first heat conducting plate 211, the second heat conducting plate 221, and the wave layer 400 are all made of copper. Furthermore, by providing several first heat dissipation holes 500 and several second heat dissipation holes 600, the busbar body 300 is connected to the first heat conducting plate 211 and the second heat conducting plate 221, effectively dissipating heat.

[0028] In the above embodiment, after the copper busbar body 300 is connected to the first heat conducting plate 211 and the second heat conducting plate 221, it can be installed on the first connecting frame 110 and the second connecting frame 120, that is, the two first wiring terminals 112 are passed through the two first through-holes, and the two second wiring terminals 122 are passed through the two second through-holes, and then the circuit is connected to the outside through wires, that is, the wiring is performed by connecting the two first wiring terminals 112 and the two second wiring terminals 122, and then the two first wiring terminals 112 and the two second wiring terminals 122 are tightened, which not only tightens the wires but also fixes the two first fixing blocks 212 and the two second fixing blocks 222 respectively, that is, indirectly fixes the first heat conducting plate 211 and the second heat conducting plate 221, and therefore, can effectively fix the copper busbar body 300.

[0029] That is, the corresponding copper busbar bodies 300 can be installed on the first connecting frame 110 and the second connecting frame 120 according to specific needs. That is, the number of the copper busbar bodies 300 is specifically set according to specific needs, which is not described in detail in this embodiment.

[0030] It is worth mentioning that since the fixing plate 130 is a telescopic plate, that is, during use, the length of the telescopic plate can be adjusted accordingly according to the length of the copper busbar body 300, so that the telescopic plate can well connect the first connecting frame 110 and the second connecting frame 120.

[0031] In summary, the above embodiments are not limitative embodiments of the present invention, and any modifications or equivalent variations made by those skilled in the art based on the essential content of the present invention are within the technical scope of the present invention.
