The connection method of the laminated busbar 3 and the laminated busbar main body 1 is simple and convenient, so as to facilitate quick plugging and fixing. At the same time, the angle of the laminated busbar 3 can be adjusted to ensure that the user can adjust it according to the installation requirements. The connecting block 201 forms a rotating structure with the laminated busbar main body 1 through the rotating rod 202, and the connecting block 201 forms a detachable structure with the laminated busbar main body 1 through the first latch 207 and the slot 204. The first latch 207 is connected to the fixing seat through the first spring 206 The seat 205 constitutes an elastic structure, and two fixing seats 205 are symmetrically arranged about the vertical center axis of the connecting block 201. The connecting laminated busbar 3 forms a locking structure with the connecting block 201 through the locking block 211, and the locking block 211 forms a locking structure with the connecting block 201 through the second latch 210, and the second latch 210 forms an elastic structure with the connecting seat 208 through the second spring 209; the connecting laminated busbar 3 can be connected to the laminated busbar body 1 through the second spring 209 and the second latch 210. The connection method is simple and convenient, which facilitates quick plugging and fixing. The number of connected laminated busbars 3 can be easily increased or reduced, and different power demand scenarios can be flexibly responded to. At the same time, by providing a rotating rod 202, the angle of the connected laminated busbar 3 can be adjusted to ensure that the user can adjust the installation angle of the connected laminated busbar 3 according to installation requirements, and the angle of the connected laminated busbar 3 can be fixed by the first latch 207.

[0028] like Figure 1 、 Figure 5 and Figure 6As shown, a laminated busbar includes a heat sink 4 arranged on the outer wall of the laminated busbar body 1, the laminated busbar body 1 includes a conductive layer 101, an intermediate insulating layer 102, an outer wall insulating layer 103, and a protective layer 104. The laminated busbar body 1 is separated by an intermediate insulating layer 102 or an outer wall insulating layer 103 between each conductive layer 101 to ensure electrical isolation between each layer. The heat sink 4 is arranged at equal intervals about the outer wall of the laminated busbar body 1, and the cross-sectional shape of the heat sink 4 is set to "L" shape, and the material of the heat sink 4 is set to aluminum-copper alloy, and the material of the intermediate insulating layer 102 and the outer wall insulating layer 103 is set to aluminum-copper alloy. The material of the protective layer 104 is set to epoxy resin, and the material of the protective layer 104 is set to high emissivity material; each conductive layer 101 is separated by an intermediate insulating layer 102 or an outer wall insulating layer 103, and the material of the intermediate insulating layer 102 and the outer wall insulating layer 103 is set to epoxy resin. Epoxy resin has high dielectric properties, which means that it can store energy in an electric field.

In addition, a protective layer 104 is provided to prevent the laminated busbar body 1 from being corroded, oxidized and mechanically damaged by the external environment during use.

[0029] Working principle: First, an intermediate insulating layer 102 or an outer wall insulating layer 103 is provided between each conductive layer 101 in the laminated busbar body 1 to ensure electrical isolation between each layer, wherein the intermediate insulating layer 102 and the outer wall insulating layer 103 are made of epoxy resin. Since epoxy resin has high dielectric properties, it means that it can store energy in the electric field and has a high resistivity, which can effectively prevent the passage of current, thereby providing a good insulation effect. In addition, a protective layer 104 is provided on the surface of the laminated busbar body 1. The protective layer 104 is made of a high emissivity material to prevent the laminated busbar body 1 from being corroded, oxidized and mechanically damaged by the external environment during use. On the other hand, a heat sink 4 is provided on the side of the laminated busbar body 1. The material of the heat sink 4 is set to be an aluminum-copper alloy. Copper is an excellent thermal conductor with a thermal conductivity much higher than that of aluminum. Adding copper to aluminum can significantly improve the thermal conductivity of the alloy, thereby enhancing its heat dissipation capacity. The rapid thermal diffusion ability of the aluminum-copper alloy helps to quickly disperse the concentrated heat to a larger surface area, thereby improving the heat dissipation efficiency.

[0030] Next, when it is necessary to connect the connecting laminated busbar 3 to the laminated busbar body 1, the second latch 210 can be toggled. At this time, the second latch 210 will be retracted into the connecting seat 208 by squeezing the second spring 209. Then the block 211 can be placed into the connecting block 201. At this time, the second latch 210 is released. The second latch 210 will be extended from the connecting seat 208 under the elastic force of the second spring 209, thereby connecting and fixing the connecting laminated busbar 3 to the laminated busbar body 1. When the angle of the connecting laminated busbar 3 needs to be adjusted during the installation process, At this time, the first latch 207 can be pulled. At this time, the first latch 207 will be retracted into the fixing seat 205 by squeezing the first spring 206. At this time, the connecting laminated busbar 3 can be rotated on the side of the connecting block 201 by the rotating rod 202. When the angle adjustment of the connecting laminated busbar 3 is completed, the first latch 207 can be released. At this time, the first latch 207 will pop out under the elastic force of the first spring 206, and the first latch 207 is inserted into the hole corresponding to the slot 204 and the side of the laminated busbar body 1. In this way, the angular position of the connecting laminated busbar 3 can be adjusted according to installation needs.
