AI Technical Summary
FPC cables are prone to wear, cracking, or breaking during repeated folding and unfolding of the leather keyboard, resulting in a short lifespan.
Two protective layers are installed in the folding area of the FPC line. High-temperature adhesive paper, Mylar or PET soft and bend-resistant material are used as protective layers to cover the upper and lower surfaces of the FPC line and slide freely in the folding area to avoid direct contact. The additional protective layer prevents wear.
It significantly increases the maximum number of folds for FPC lines, extending their service life, with the number of folds increasing from 5,000 to over 10,000.

Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic device technology, and in particular to a leather keyboard and its FPC cable protection structure. Background Technology
[0002] Currently, small, portable electronic devices such as mobile phones, MID (Mobile Internet Device), and tablets have become necessities for people and are widely used in both daily life and work.
[0003] Leather keyboard cases that combine protection and keyboard input are now available on the market, allowing connection to smartphones, MIDs, tablets, and other electronic devices. These cases connect magnetically, requiring no charging and are ready to use immediately upon connection – very convenient. Typing with a leather keyboard is more convenient and faster than using the virtual keyboard on a smartphone, MID, or tablet, and users are more accustomed to its use. The leather keyboard case protects smartphones, MIDs, and tablets from drops, scratches, dust, and water. It can also function as a stand for smartphones, MIDs, and tablets, providing better viewing of the display screen.
[0004] The leather keyboard case comprises two main parts: a leather case and a keyboard. The leather case includes a keyboard area for mounting and securing the keyboard, a first folding area connecting to the keyboard area, a first flip-up area connecting to the first folding area, a second folding area connecting to the first flip-up area, and a second flip-up area connecting to the second folding area. The leather case can be folded and rotated via the first and second folding areas.
[0005] The leather keyboard is electrically connected to external electronic devices via an FPC cable. One end of the FPC cable electrically connects to a POGO PIN connector, which then connects to the electronic device. The other end connects to the keyboard's built-in motherboard. The FPC cable is sandwiched within a first folding area, a first flip-over area, a second folding area, and a second flip-over area. Because the first and second folding areas are frequently folded and rotated, the FPC cable sandwiched within is prone to breakage after repeated stretching and bending, resulting in a failure to maintain the electrical connection and a short lifespan.

[0058] When the keyboard case of this invention is folded and rotated, the FPC cable 29 sandwiched in the first folding area 13 does not directly contact the upper first folding area cover plate 392 or the lower first folding area bottom plate 212. A first protective layer 31 is added between the FPC cable 29 and the first folding area cover plate 392 and between the FPC cable 29 and the first folding area bottom plate 212, which can protect the FPC cable 29 and prevent it from being worn, cracked or broken. At the same time, the FPC cable 29 can slide freely within the two first protective layers 31, which can greatly increase the maximum number of folds of the FPC cable 29 and significantly extend the service life of the FPC cable 29.
[0059] Similarly, two second protective layers 33 are added between the FPC line 29 sandwiched in the second folding zone 17 and the upper second folding zone cover plate 394 and the lower second folding zone bottom plate 214. These layers can protect the FPC line 29 and prevent it from being worn, cracked, or broken. At the same time, the FPC line 29 can slide freely within the two second protective layers 33, which can greatly increase the maximum number of folds of the FPC line 29 and significantly extend its service life.
[0060] In existing leather keyboard cases, the FPC cable 29 breaks after being folded nearly 5,000 times. However, tests have shown that the FPC cable 29 of this invention will not break after being folded more than 10,000 times, significantly extending the service life of the FPC cable 29.
[0061] The present invention proposes an FPC line protection structure, which includes a sheath 1, two first protective layers 31 and two protective layers 33.
[0062] The leather case 1 includes a keyboard area 11, a first folding area 13 connected to the keyboard area 11, a first folding area 15 connected to the first folding area 13, a second folding area 17 connected to the first folding area 15, a second folding area 19 connected to the second folding area 17, and an FPC cable 29.

[0064] The second turning zone 17 includes a second turning zone base plate 214 and a second turning zone cover plate 394 fixed on the second turning zone base plate 214.
[0065] FPC line 29 is sandwiched between the first folding zone 13, the first flip zone 15, the second folding zone 17, and the second flip zone 19.
[0066] The two first protective layers 31 and the two second protective layers 33 are made of soft, bend-resistant materials such as high-temperature adhesive paper, Mylar, and PET (polyethylene glycol terephthalate).
[0067] Two first protective layers 31 are fixed to the first folding area 13 and respectively cover the upper and lower surfaces of the FPC line 29 located in the first folding area 13.
[0068] The first protective layer 31 covering the upper surface of the FPC line 29 is fixed to the lower surface of the first folding area cover plate 392, and the first protective layer 31 covering the lower surface of the FPC line 29 is fixed to the upper surface of the first folding area bottom plate 212. The FPC line 29 can slide freely between the two first protective layers 31.
[0069] Two second protective layers 33 are fixed to the second folding area 17 and respectively cover the upper and lower surfaces of the FPC line 29 located in the second folding area 17.
[0070] The second protective layer 33 covering the upper surface of the FPC line 29 is fixed to the lower surface of the second turning area cover plate 394, and the second protective layer 33 covering the lower surface of the FPC line 29 is fixed to the upper surface of the second turning area bottom plate 214.

[0071] The FPC line 29 sandwiched in the first folding zone 13 does not directly contact the upper first folding zone cover plate 392 or the lower first folding zone bottom plate 212. A first protective layer 31 is added between the FPC line 29 and the first folding zone cover plate 392 and between the FPC line 29 and the first folding zone bottom plate 212, which can protect the FPC line 29 and prevent it from being worn, cracked or broken. At the same time, the FPC line 29 can slide freely within the two first protective layers 31, which can greatly increase the maximum number of folds of the FPC line 29 and significantly extend the service life of the FPC line 29.
[0072] Similarly, two second protective layers 33 are added between the FPC line 29 sandwiched in the second folding zone 17 and the upper second folding zone cover plate 394 and the lower second folding zone bottom plate 214. These layers can protect the FPC line 29 and prevent it from being worn, cracked, or broken. At the same time, the FPC line 29 can slide freely within the two second protective layers 33, which can greatly increase the maximum number of folds of the FPC line 29 and significantly extend its service life.
[0073] In existing leather keyboard cases, the FPC cable 29 breaks after being folded nearly 5,000 times. However, tests have shown that the FPC cable 29 of this invention will not break after being folded more than 10,000 times, significantly extending the service life of the FPC cable 29.
