The present invention will be described in detail below with reference to embodiments shown in the drawings. The embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to the embodiments are included in the scope of the present invention.

The utility model discloses a female arranging of stromatolite for power battery, including a plurality of layers of range upon range of unit, every layer of range upon range of unit is at least including forming in outmost two-layer insulating layer, forming in the conductive layer between two-layer insulating layer and being connected to the FFC circuit arrangement on the conductive layer. Two insulating layers in the unit provide insulation protection for a conductor layer on the inner side of the unit, an FFC circuit device and the like, and the laminated busbar of the product has good use safety and stability.

In the above scheme, in order to meet the positioning requirement, at least one of the two insulating layers is provided with a positioning hole, and at this time, the corresponding unit structure can be positioned at least from the insulating layer on one side. More preferably, the two insulating layers are each formed with a positioning hole, so that positioning operation can be performed from the insulating layers on both sides. At this time, the central axes of the positioning holes on the two insulating layers may be coincident or non-coincident. That is, the central axes of at least part of the positioning holes formed on the two insulating layers of the same unit are overlapped.

In the above solution, the positioning hole with the overlapped central axis in each unit penetrates through at least the laminated unit where the positioning hole is located to form a through hole, that is, when the insulating layers on both sides have the positioning with the overlapped central axes, the conductor layer therebetween also has a through hole corresponding to the positioning hole, so that the laminated unit structure of the layer can be penetrated through the positioning hole in the unit. Further, the through-hole position penetrates more of the multilayer laminated unit in the central axis direction thereof, that is, the multilayer laminated structure has a penetrating structure at the same position to form a through-hole penetrating the multilayer laminated unit. Furthermore, the through holes penetrate through the whole laminated busbar for the power battery along the central axis direction, namely the through holes formed by the positioning holes penetrate from one side of the busbar to the other side of the busbar, and a hole structure penetrating through the busbar in the thickness direction is formed.
