Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery stop frames, in particular to an insulating stop frame for a lithium battery module. Background Art

[0002] In the production process of square lithium-ion power batteries, since the positive and negative electrodes need to be led out from the inside of the battery, a certain distance must be reserved between the cover plate and the winding core inside the battery to allow the connection piece to connect with the positive and negative ears. During the use of the battery, it will bump along with the vehicle body. If there is no object between the winding core and the top cover to prevent the winding core from moving up and down with the movement of the battery, it will cause safety hazards over time; in addition, the connecting piece and the cover plate pole are laser welded, which is easy to produce fine welding slag, which falls into the battery cell and causes short circuit thermal runaway, and some existing lithium battery insulation stoppers cannot fix multiple groups of lithium batteries together, resulting in the stopper being unable to combine multiple groups of lithium batteries into a battery module.

[0003] A Chinese patent with a publication (announcement) number of CN203481293U discloses an insulating stop frame for a lithium battery, comprising a metal shell of a lithium battery, a top cover being provided on the metal shell, a battery cell being placed in the metal shell, the positive and negative electrode lines of the battery cell being connected to the positive and negative electrode lead-out lines of the top cover, and also comprising a semi-cylindrical stop block, a cylindrical through hole being provided in the middle of the semi-cylindrical stop block, a left arc-shaped insulating sheet and a right arc-shaped insulating sheet being provided at the left and right ends of the front and rear sides of the semi-cylindrical stop block respectively, two left arc-shaped insulating sheets, two right arc-shaped insulating sheets and the middle semi-cylindrical stop block being injection-molded into an integral structure, the injection-molded integral structure being placed in the metal shell and pressed on the battery cell, the left arc-shaped insulating sheet and the right arc-shaped insulating sheet wrap the positive and negative electrode lines of the battery cell and the positive and negative electrode lead-out lines of the top cover connected thereto without touching the metal shell.
