Embodiment Construction

[0019] Such as Figure 1-Figure 2 As shown, a soft-packed lithium battery assembled tab PCB includes a PCB board 1 and a cell with a punched tab. The PCB board 1 is also provided with a number of positive and negative wire grooves, and the cell corresponds to the positive and negative poles. The number of negative wire slots, and the battery cores are inserted into the positive and negative wire slots in turn to fix them. The PCB board 1 has an electrical connection part. The connecting part is electrically connected, and also includes a screw 2, a gasket 3, a nut 4 and a connecting piece 5. The PCB board 1 is provided with a screw hole, and the screw 2 is threadedly connected to the screw hole. The head of the screw 2 Fixedly assembled with the PCB board 1, the connecting piece 5, the gasket 3 and the nut 4 are sequentially arranged at the tail of the screw 2, the tab is directly clamped and fixed by the PCB board 1 and the connecting piece 5, and the nut 4 and the threaded ...

Abstract

The invention relates to a PCB, in particular to a soft package lithium battery assembly tab PCB and a process thereof. The problem of assembling a soft package lithium battery is solved. The PCB comprises a PCB body and battery cells with stamped tabs, and the PCB is also provided with a plurality of positive and negative wire ducts. The battery cells correspond to the positive and negative wireslots in number; the battery cells are sequentially inserted into the positive and negative wire slots to be fixed; the PCB is provided with electric connection parts; the tabs on the battery cells are oppositely folded in pairs to be in contact with each other; the tabs are electrically connected with the electric connection parts in a contact manner; the PCB further comprises screws, gaskets, nuts and connecting pieces; the PCB is provided with screw holes; the screws are in threaded connection with the screw holes; the tabs are directly clamped and fixed through the PCB and the connecting pieces; and the nuts are in threaded connection with the screws. Thus, small-batch large-scale standardized assembly production of the soft package lithium batteries can be realized, the minimization of the volume of a battery pack is improved, the assembly process is convenient, the production cost is low, after-sales maintenance is convenient, and the existing use requirements can be met.

Description

technical field [0001] The invention relates to a PCB board, in particular to a soft-packed lithium battery assembly lug PCB and a process thereof. Background technique [0002] At present, the assembly of some soft-packed lithium batteries by echelon is faced with the actual situation that there are many specifications and models, and the number of single models is small, and it is impossible to carry out large-scale and standardized PACK production. At the same time, a large part of the step-by-step utilization of lithium batteries will be used in civilian electric vehicles in the future. However, civil vehicles such as two-wheeled electric bicycles have strict limitations on the volume of the battery pack, and the existing product structure cannot meet the design requirements at all. Contents of the invention [0003] Aiming at the deficiencies of the existing technologies, the present invention provides a soft-packed lithium battery assembly lug PCB and a process ther...
