Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1-first layer of protective plate 2-second layer of protective plate 3-structural member 4-through hole.
Detailed Description
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to FIG. 1
The utility model provides a can lead to double-deck board stack structure of heavy current, is located the structure 3 that has laid a plurality of electrically conductive materials between first layer protection shield and the second layer protection shield including setting up in the battery package and first layer protection shield 1 and the second layer protection shield 2 of laying from top to bottom, the both ends of structure respectively with need walk the position fixed connection of electric current on the protection shield to realize the connection and the electrically conductive intercommunication of two-layer protection shield.
In this embodiment, in order to better realize that the first layer of protection shield and the second layer of protection shield are electrically connected to guarantee the joint strength of first layer of protection shield and second layer protection, a plurality of through-holes 4 have all been seted up to the position that needs to walk electric current on first layer of protection shield and the second layer of protection shield, and the protection shield surface in the region of through-hole place is provided with the pad to the structure is welded and is linked to each other. And two ends of the structural member respectively penetrate through the through holes of the corresponding protection plates and are welded with the welding pads through tin soldering.
In this embodiment, in order to better maintain the distance between the first layer of protection plate and the second layer of protection plate, the structural member is a screw column structure, and the outer diameter of the middle section of the structural member is larger than the outer diameters of the two end portions of the structural member.
In this embodiment, the cross-section of the middle section of the structural member is polygonal, such as hexagonal or other post with larger outer diameter. The two ends of the structural member are cylindrical so as to be better welded with the welding pad through the through hole.
In this embodiment, in order to ensure conductivity, the structural member is made of a material plated with nickel copper.
During installation:
the two ends of the screw column respectively penetrate through the corresponding protection plates, and the two ends of the screw column and the welding pads of the protection plates are connected in a soldering and fastening mode, so that connection is formed.
The above mentioned is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be included in the scope of the present invention.
