Soft packing cell and air tight type conductive connection structure and assembling process

Abstract

The invention provides a battery with soft package, airtight type conduction connecting structures and an assembling method thereof. The battery with soft package comprises a battery pole coil, a soft package and a pair of airtight type conduction connecting structures. Each airtight type conduction connecting structure comprises a conductive terminal and a pressing built-in fitting. The conductive terminal is used for conducting current of the battery pole coil to the outside and comprises a bottom plate and a projection. The bottom plate is arranged in the soft outer package and connected with the battery coil and the projection is arranged at the bottom plate and penetrates through the upper surface of the soft outer package. The pressing built-in fitting is used for pressing and fixing the soft outer package and the conductive terminal and comprises a holding plate. The holding plate comprises a first holding part, a second holding part and a turning part which connects the first holding part and the second holding part, leads the first holding part to be sheathed on the projection and stick to the upper surface of the soft outer package flat and leads the second holding part to stick to the lower surface of the soft outer package flat.

Description

technical field [0001] The present invention relates to a battery and its assembly method, and in particular to a soft package battery, its conductive connection structure and the assembly method of the soft package battery. Background technique [0002] In the market, batteries are installed on the market, whether it is as small as a popular portable electronic product or as large as a car for transportation. The battery is the power source of most portable electronic products at present, so how to reduce the production cost of the battery and provide consumers with a safe and good battery has always been the goal of the industry. [0003] Please refer to figure 1 and figure 2 , figure 1 A schematic diagram showing a traditional flexible packaging battery, figure 2 draw figure 1 Sectional view of dashed line 2-2'. like figure 2 As shown, the flexible package battery 100 includes a battery pole roll 110, a flexible outer package 120, a pair of inner conductive lead...

Problems solved by technology

However, rivets are prone to stress corrosion and joint gaps and other factors that may cause liquid leakage

Moreover, the many components used in traditional flexible packaging batteries make the assembly process complex, time-consuming and labor-intensive, and it is necessary to prepare soldering or hot-melting tools, which not only makes it difficult to improve product yield, but also increases manufacturing costs.
