Technical Field

[0001] The present invention relates to an assemblable touch button. Background Art

[0002] Basically, the touch buttons installed on the existing control board are concentrated in one area, with dense distribution resulting in inconvenient operation. In addition, remote control cannot be achieved. Summary of the Invention

[0004] The assemblable touch button of the present invention includes a strip-shaped circuit area connected to a pressing area for finger pressing, and comprises seven layers connected in sequence to form a whole: an appearance layer, a first double-sided adhesive layer, a shielding layer, a substrate layer, a wiring layer, a second double-sided adhesive layer, and a first release film layer. Both the shielding layer and the wiring layer are metal layers, fixed on both sides of the substrate layer, wherein the shielding layer is located in the circuit area. At each end of the second double-sided adhesive layer and the first release film layer away from the pressing area, there is a corresponding through hole, and a conductive double-sided adhesive is provided in the two through holes. One side of the conductive double-sided adhesive located on the side of the wiring layer is adhered to the wiring layer, and a second release film layer is provided on the other side. After such a setting, the second release film layer on the conductive double-sided adhesive in the circuit area is peeled off and adhered to the induction point on the control board, and the touch button is assembled onto the control board, and the touch button is led to a position far from the control board, so as to achieve remote control, which is convenient to use and also reduces the problem of inconvenient operation due to the dense distribution of touch buttons on the control board.

[0005] In order to improve the reliability of the touch button and facilitate finger pressing, the width of the circuit area is greater than 5 cm and less than 8 cm, the pressing area is circular, and the area is larger than the area of the finger pressing surface.

[0006] In order to improve the reliability of the touch button, both the appearance layer and the substrate layer are PET films with a thickness of less than 0.05 mm, and both the shielding layer and the wiring layer are copper layers, fixed on both sides of the substrate layer by plating.

[0007] In order to further improve the reliability of the touch button, the thickness of the appearance layer is 0.023 mm, the thickness of the substrate layer is 0.05 mm. One side edge of the shielding layer away from the pressing area and the two long sides connected to the one side edge are all inside the corresponding sides of the substrate layer, and are 0.5 mm away from the corresponding sides of the substrate layer. The width of the part of the wiring layer located in the circuit area is 0.8 - 1 mm, and the contour line of the part located in the pressing area is inside the contour line of the part of the substrate layer located in the pressing area, and the two contour lines are 0.5 mm apart. The diameter of the through holes in the second double-sided adhesive layer and the first release film layer is 3 mm.

[0008] Beneficial effects: The touch button of the present invention has a pressing area and a strip-shaped circuit area. After the touch button is installed on the control board, the strip-shaped circuit area enables the pressing area to be distributed in different places outside the control board, solving the problem of dense buttons in the past and realizing remote control at the same time; by setting the width of the circuit area to be greater than 5 cm and less than 8 cm, setting the pressing area to be circular and having an area larger than the area of the finger pressing surface, the reliability of the touch button is improved and it is convenient for finger pressing; by setting both the appearance layer and the base material layer to be PET films with a thickness of less than 0.05 mm, and setting both the shielding layer and the wiring layer to be copper layers and fixing them on both sides of the base material layer by plating, the reliability of the touch button is improved; by setting the thickness of the appearance layer to be 0.023 mm, the thickness of the base material layer to be 0.05 mm, the shielding layer to be located within the contour line of the base material layer in the circuit area and 0.5 mm away from the contour line, the width of the part of the wiring layer located in the circuit area to be 0.8 - 1 mm, located within the contour line of the base material layer in the pressing area and 0.5 mm away from the contour line, and setting the diameter of the through holes on the second double-sided adhesive layer and the first release film layer to be 3 mm, the reliability of the touch button is further improved.

Detailed Embodiments

[0013] The technical solution of the present invention will be described in detail below through embodiments, but the protection scope of the present invention is not limited to the described embodiments.

[0014] As Figures 1 - 3 shown, an assemblable touch button includes a strip-shaped circuit area 9 connected to each other and a pressing area 8 for finger pressing, and includes seven layers connected in sequence to form an integral body: an appearance layer 1, a first double-sided adhesive layer 2, a shielding layer 3, a base material layer 4, a wiring layer 5, a second double-sided adhesive layer 6, and a first release film layer 7.

[0015] The length of the circuit area 9 is not particularly limited and can be set as needed. The width of the circuit area 9 is greater than 5 cm and less than 8 cm. The area of the pressing area 8 is larger than the area of the finger pressing surface, and the shape is not particularly limited, such as triangular, square, or polygonal, preferably circular.

[0016] Both the appearance layer 1 and the base material layer 4 are PET films, and their thicknesses are both below 0.05 mm. Preferably, the thickness of the appearance layer 1 is 0.023 mm and the thickness of the base material layer 4 is 0.05 mm.

[0017] Both the shielding layer 3 and the wiring layer 5 are metal layers, which are fixed on both sides of the base material layer 4 by plating. One of the metal layers is processed into the shielding layer 3, and the shielding layer 3 is located in the circuit area 9. The other metal layer is processed into the wiring layer 5. The above metal layer is preferably a copper layer. One side edge of the shielding layer 3 away from the pressing area 8 and the two long sides connected to this side edge are all inside the corresponding sides of the base material layer 4, and are all 0.5 mm away from the corresponding sides of the base material layer 4. The width of the part of the wiring layer 5 located in the circuit area 9 is 0.8 - 1 mm, and the contour line of the part located in the pressing area 8 is inside the contour line of the part of the base material layer 4 located in the pressing area 8, and the two contour lines are 0.5 mm apart.

[0018] The appearance layer 1 is adhesively fixed on the shielding layer 3 and the base material layer 4 through the above first double-sided adhesive layer 2. On the surface of the pressing area 8 of the appearance layer 1 that contacts the finger, indicative patterns such as arrows can be provided; the first release film layer 7 is adhesively fixed on the wiring layer 5 and the base material layer 4 through the above second double-sided adhesive layer 6, and the first release film layer 7 also serves as a protective layer at the same time.

[0019] A corresponding through hole is provided at each end of the second double-sided adhesive layer 6 and the first release film layer 7 away from the pressing area 8. The through hole is preferably a round hole with a diameter of 3 mm. A conductive double-sided adhesive 61 is provided in the two through holes. One side of the conductive double-sided adhesive 61 located on the wiring layer 5 side is adhered to the wiring layer 5, and the other side is provided with a second release film layer (not shown) as a protective layer.

[0020] In actual manufacturing, after the layers are adhered and fixed in sequence, the outer shape of the touch button can be punched out by laser or die cutting (as Figure 1 shown). In actual use, first peel off the second release film layer to expose the conductive double-sided adhesive 61 and adhere it to the induction point on the control board, then peel off the first release film layer 7 and adhere and fix it on the passing path to fix the touch button, and then it can be used. After pressing the pressing area 8, the signal is transmitted to the induction point on the control board through the wiring layer 5 and the double-sided conductive adhesive 61 in the circuit area 9, realizing the long-distance control function.
