Problems solved by technology

[0004] In the prior art, it is generally blocked by wrapping adhesive tape and sealant with people, which is time-consuming and laborious, which increases the labor intensity of workers, increases labor costs, and lowers the test efficiency.
At the same time, if this method is used for sealing, the sealing effect is poor, and it cannot withstand the relatively high pressure during the test, which seriously affects the test effect

Abstract

The invention discloses a lithium battery pack air tightness test explosion-proof valve plugging clamp. By cooperation of a cover board, a sealing base and design of drag hooks at two sides, an effectof sealing and compacting is realized, fast sealing for an explosion-proof valve is realized, sealing effect is good, pressure bearing capability and test efficiency in test are improved, and test accuracy is guaranteed. By an elastic component arranged, detaching is facilitated, work intensity of workers is reduced, the clamp can be operated quickly and efficiently, and is time-saving and labor-saving; and the clamp is simple in structure, low in manufacture cost, can be reused for many times, thus, usage cost is reduced further, and generalization in a wide range is facilitated.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a plugging fixture for an explosion-proof valve for air tightness testing of lithium battery packs. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium battery module refers to the combination of lithium batteries connected in series and parallel, and after protecting the circuit board and casing, it can directly supply power. [0003] During the production process of the lithium battery pack, it is necessary to test the air tightness of the battery pack to judge the waterproof and dustproof ability of the battery pack. During the detection, it is necessary to inflate the inside of the battery pack and test the internal pressure of the battery pack to achieve the purpose of testing the battery pack air. However, there is an exp...
