Description

Technical Field

[0001] The utility model belongs to the technical field of touch modules, and in particular relates to a touch module for preventing circuit oxidation. Background Art

[0002] The touch screen includes internal transparent conductive wires, peripheral metal leads, and a flexible circuit board connected to the metal circuits. In order to ensure a better effect of the touch screen, the peripheral metal circuits are usually printed with silver paste ink with good conductivity. When designing, grooves need to be opened on the touch screen sensor to leave a space to allow the flexible circuit board to align and fit the silver paste circuits.

[0003] Since silver is a highly active metal material, it is very easy to oxidize to form non-conductive silver sulfide when exposed to air, which will affect the service life of electronic products and cause functional hazards. At present, in order to prevent the oxidation of silver paste circuits, dispensing or printing ink is usually used to protect the silver paste circuits to avoid circuit oxidation.

[0004] For example, in the prior art, a Chinese utility model patent with authorization announcement number CN216352257U discloses "a touch module and touch screen for preventing circuit oxidation", including an ITO film, a silver paste circuit is provided on the periphery of the ITO film, and a transparent insulating ink layer is printed on the ITO film. The coverage range of the transparent insulating ink layer can cover the silver paste circuit area. Compared with the prior art, the oxidation of the exposed silver paste circuit is avoided and the processing is convenient.

[0005] Although the anti-circuit oxidation touch modules in the prior art, including those mentioned above, can effectively prevent oxidation of exposed silver paste circuits, the installation stability of the flexible circuit board is insufficient. Currently, the connection between the flexible circuit board and the chip mostly adopts a fixed connection method such as welding, connector insertion or direct bonding. Because the flexible circuit board is relatively soft, the flexible circuit board is prone to loose connection due to shaking during the processing and assembly of the touch module, affecting its use.

[0006] In order to solve the above problems, the present application proposes a touch control module for preventing circuit oxidation. Utility Model Content

[0010] A plurality of limit blocks are fixed to the bottom surface of the flexible edge guard and are used to support the flexible circuit board.

[0011] As a preferred technical solution of the present invention, the outer wall of the flexible circuit board is tightly fitted to the inner wall of the positioning groove.

[0012] As a preferred technical solution of the utility model, the flexible edge protector is a silicone component.

[0013] As a preferred technical solution of the present utility model, the flexible edge guard and the limit stopper are an integrated structure formed by hot pressing.

[0014] As a preferred technical solution of the utility model, it also includes:

[0015] Fixed feet are fixed at both ends of the flexible edge guard, and the fixed feet are provided with fixing holes.

[0018] Insulating rubber pads are bonded and fixed to the bottom surfaces of the first touch module and the second touch module, and anti-wear bumps are evenly distributed on the insulating rubber pads.

[0019] As a preferred technical solution of the utility model, heat dissipation holes are evenly opened on the insulating rubber pad.

[0020] Compared with the prior art, the beneficial effects of the utility model are:
