Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0018] See attached document Figures 1-3This utility model provides a high-safety laminated busbar, comprising a copper busbar body 100, which includes copper conductive busbars 110 and PI film layers 120. Multiple layers of copper conductive busbars 110 and PI film layers 120 are alternately laid, meaning that a PI film layer 120 with a thickness of 0.1~0.5mm can be laid between two layers of copper conductive busbars 110, and then bonded together by hot pressing to form a "conductive layer-insulating layer". The copper busbar body 100 has a layered structure that isolates the conductor and prevents flame spread at high temperatures. An outer protective layer 200, which is a first insulating layer 210, is provided on the outer wall of the copper busbar body 100 to improve its insulation effect. The first insulating layer 210 can be made of TPE material, which has insulating and flame-retardant properties, while also providing good elasticity and flexibility, allowing for bending. A first reinforcing layer 220, which enhances the overall structural strength of the busbar, is wrapped around the outer wall of the first insulating layer 210. The thickness of the first reinforcing layer 220 is greater than that of the first insulating layer 210. The first reinforcing layer 220 can be made of carbon fiber-ring. The oxygen resin composite layer can improve the overall strength of the busbar. The outer wall of the first reinforcing layer 220 and the side away from the first insulating layer 210 are wrapped with an outer flame-retardant protective layer 230. The thickness of the outer flame-retardant protective layer 230 is greater than that of the first reinforcing layer 220. The outer flame-retardant protective layer 230 can be made of silicone with flame-retardant and corrosion-resistant properties, which can improve the overall protection of the busbar. The outer wall of the outer flame-retardant protective layer 230 and the side away from the first reinforcing layer 220 are coated with a first anti-corrosion coating 240. The coating thickness of the first anti-corrosion coating 240 is 20~30μm. The first anti-corrosion coating 240 can be a nickel-plated coating, which can further improve the anti-corrosion properties of the outer flame-retardant protective layer 230.

[0019] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, that is, fix the PI film layer 120 between the two copper conductive busbars 110 by hot pressing to prepare the composite layer copper busbar body 100. Then, the first insulating layer 210 can be taken out and wrapped around the outer layer of the copper busbar body 100. The first insulating layer 210 can be fixed to the outside of the copper busbar body 100 by adhesive. Then, the first reinforcing layer 220 and the outer flame-retardant protective layer 230 are taken out. Then, the first reinforcing layer 220 and the outer flame-retardant protective layer 230 are wrapped around the outer wall of the first insulating layer 210 in sequence and fixed in sequence by heat-resistant adhesive. Finally, a first anti-corrosion coating 240 is sprayed on the outside of the outer flame-retardant protective layer 230 to improve the anti-corrosion performance of the outer flame-retardant protective layer 230. Example

[0020] See attached document Figures 2-4Compared to Embodiment 1, the difference in this embodiment is that the outer protective layer 200 is a second insulating layer 250. The second insulating layer 250 wraps around the outer wall side of the copper busbar body 100 to improve the insulation effect of the copper busbar body 100. The second insulating layer 250 can be made of polyamide (polymer) plastic, which can provide excellent insulation performance. The outer wall side of the second insulating layer 250 is wrapped with a heat insulation layer 260 to improve the overall heat insulation performance of the busbar. The heat insulation layer 260 can be made of Teflon material, which has excellent insulation and heat insulation properties, and can prevent the metal outer protective layer 27 from being damaged. The heat transferred from the 0 is transferred to the copper busbar body 100. The thickness of the heat insulation layer 260 is greater than that of the second insulation layer 250. The outer wall of the heat insulation layer 260 is wrapped with a metal outer protective layer 270 to improve the flame retardant protection performance of the busbar. The outer layer of the metal outer protective layer 270 is sprayed with a second anti-corrosion coating 280. The material of the metal outer protective layer 270 can be selected as the metal sheath of the busbar, which can enhance the strength of the busbar and provide good protection performance. The second anti-corrosion coating 280 can be selected as fluorocarbon coating (PVDF), which can provide good anti-corrosion performance.

[0021] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
