Description

Conductive leaflet

[Technical Field]

The application relates to the field of circuit technology, in particular to a conductive leaf.

 【Background technique】

At present, in order to extend the use time of electronic products such as mobile phones, tablet computers, etc., the protective leather case of the electronic product can be set as a power source for the electronic product. Generally, the front and back covers of the protective leather case of the electronic product can be provided with a battery. When the battery is disposed on the front cover, the battery is connected to the main board on the back of the electronic product through the cable between the front and rear covers to supply power to the main board.

However, when the electronic product is used, it is often necessary to flip the front cover of the protective holster, and at this time, the cable disposed between the front and rear covers will also be folded over. Electronic products are often used frequently, resulting in an annual turnover of 20,000 to 80,000 times. Such frequent folding is likely to cause the copper wire inside the cable to break due to metal fatigue. Therefore, the existing cable life cannot meet the frequent flipping requirements of electronic products.
