The conductive copper sheet is in contact with the conductive metal strip, but because the conductive copper sheet may have poor contact, the conductive copper sheet is generally designed as an elastic part. Since the conductive copper sheet may have metal fatigue, poor design and other factors, there is still a problem of poor contact due to insufficient elasticity.
