Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery pole ears, and more specifically to a lithium battery pole ear that is resistant to deformation. Background Art

[0002] The tab is a raw material for lithium-ion polymer battery products. The battery is divided into positive and negative poles. The tab is a metal conductor that leads the positive and negative poles out of the battery cell. With the development of technology, lithium batteries have become mainstream and are also used in new energy vehicles to provide power output.

[0003] When used, the existing lithium battery tabs are usually a single metal structure and are directly welded and connected through conductors to allow the batteries to be connected in series. The overall connection strength lies in the connection strength of the welding points. When subjected to external forces, the battery is offset and easily pulls on the tabs, causing the tabs to deform or the conductors to break, resulting in the lithium battery being unable to perform normal charge and discharge operations. For this reason, we propose a deformation-resistant lithium battery tab. Utility Model Content

When subjected to external force, the connecting rod 11 will be pulled, so that the connecting rod 11 drives the force-bearing mounting disk 12 to move, compressing the force-bearing spring 13, and the spiral connecting wire 14 can also be retracted and expanded, which can offset the external force, thereby providing protection for the connection between the connecting bottom block 1 and the connecting plug 6, thereby improving the overall strength of use.

[0023] The other end of the connecting rod 11 is provided with a threaded connector 15 so that the threaded connector 15 can connect the connecting rod 11 to an external connecting conductor.

[0024] Among them, the connection positioning mechanism 10 includes a connection limit plug 16, a limit groove 17 is provided at the bottom end of the connection limit plug 16, and a second bolt 18 is provided at the top end of the connection limit plug 16, so that the connection limit plug 16 can be inserted into the inner side of the fixed installation groove 8, so that the connection limit plug 16 is stuck on the outer surface of the connecting rod 11 under the action of the limit groove 17, and is connected and fixed between the second bolt 18 and the top of the fixed connecting block 7, so that the connecting rod 11 can be limited to prevent it from detaching from the inner side of the fixed connecting block 7.

[0025] The inner side of the limiting groove 17 fits with the outer side of the surface of the connecting rod 11 , so that the connecting limiting plug 16 can stably limit the connecting rod 11 when it is located inside the fixed installation groove 8 .

[0026] Among them, the outer surface of the connection limit plug 16 is in contact with the inner side of the fixed installation groove 8, so that the connection limit plug 16 can be stably located inside the fixed installation groove 8 to avoid shaking and improve the overall stability of use.

The overall structure is simple and quick and convenient to use.
