Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic testing technology for FPC fuse blowout, specifically an automatic tester for FPC fuse blowout. Background Technology
[0002] In the emerging field of power battery applications, FPC (Flexible Printed Circuit) is mainly used to replace traditional wiring harnesses in the battery pack stage, assisting in the collection of information such as voltage and current of the battery pack. The quality of the copper-etched fuse in the FPC is a key factor in protecting the quality and safety of the power battery. When grounding, short circuits, or overloads occur in the battery, the fuse in the FPC will blow, thereby automatically cutting off the power supply to ensure the safety of the entire current system.
[0003] Therefore, testing the quality of FPC fuses is particularly important. Traditional fuse testing devices apply a rated current to both ends of the fuse during the experiment, and then count and collect the fuse's fusing time. Each test can only be performed on a single point. When mass production is carried out in the factory, the test period is long and the labor and equipment investment costs increase. In order to reduce the investment costs of enterprises and improve the testing efficiency, we propose an automatic FPC fuse fusing tester. Utility Model Content
