[0047] The working principle of the present invention is as follows:

[0048] When in use, the first upper protective frame 2 and the second upper protective frame 4 are pulled apart, and the display connection COF1 is placed between the first upper protective frame 2 and the second upper protective frame 4 and the first upper protective frame 2 and the second upper protective frame 4. The card frame can limit the rotation of the first upper protective frame 2 and the second upper protective frame 4. At the same time, the first upper protective frame 2 and the second upper protective frame 4 are snapped together with the first upper protective frame 2 and the second upper protective frame 4 through the card frame, which is convenient for fixing the COF. The COF is well fixed with the first protective frame assembly and the second protective frame assembly through the fitting strip. By setting a first group of connecting strips 6 and a second group of connecting strips 14, one group of connecting strips 6 can move between the first upper protective frame 2 and the second upper protective frame 4, so that when the COF is bent, the protective device can bend together and will not squeeze the COF.

The first group of connecting strips 6 can be wrapped by the first rubber sleeve 7, so that the first group of connecting strips 6 will not be deformed when bending, and the first group of connecting strips 6 can be prevented from directly squeezing the COF. The second group of connecting strips 14 can be wrapped by the second rubber sleeve 15, so that the second group of connecting strips 14 will not be deformed when bending, and the second group of connecting strips 14 can be prevented from directly squeezing the COF. The protective device can be fixed at the installation connection by the fixing plate to improve the fixation of the protective device. The connection protection plate 10 will be pressed on the COF connection under the action of the rubber pressing plate 11. The protruding part of the rubber pressing plate 11 is elastic and can press the connection protection plate 10.

[0049] Compared with the prior art, the present invention has the following beneficial effects:

[0050] (1) In the present invention, the COF is protected to prevent the COF from being scratched by other mounting components of the display during the installation process of connecting the display screen and the circuit board, thereby preventing the COF surface from being damaged. At the same time, the COF can be protected according to the different bending of the COF.

[0051] (2) In the present invention, when the COF connects the display and the circuit board, pulling the display will cause the COF to stretch, which may easily lead to the stretching of the COF and make the COF easily damaged. Therefore, the pulling of the display can be limited without affecting the installation and connection of the display.

[0052] (3) In the present invention, the connection part of COF is generally connected by pressing and gluing, which is easy to fall off. The protective device not only protects COF from damage, but also presses and reinforces the connection.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
