Description

Touch device with large nameplate

technical field

The utility model relates to a touch device, in particular to a touch device with a large-area nameplate.

Background technique

In recent years, touch devices have been widely used in consumer electronics products, such as mobile phones, digital cameras, personal digital assistants (PDAs), etc. Electronic products with display screens can be directly attached to touch devices On the outer surface of the screen, the user is allowed to operate the electronic product by pressing the touch device.

A general touch device generally includes an upper conductive plate and a lower conductive plate stacked up and down, a flexible nameplate covering the top surface of the upper conductive plate, and a flexible plate electrically connected to the lower conductive plate and electronic products. Conductive cables. Among them, in order to flatten the touch device, it can be flatly embedded and fixed on the screen of the electronic product, and cover the image displayed on the entire screen, thereby forming a so-called electronic product with a full flat touch screen. The length of the touch device The width is usually larger than the screen, that is, the upper conductive plate, the lower conductive plate and the name plate are all larger than the screen.

At present, this type of touch device used to manufacture a full-flat touch screen usually has a nameplate whose length and width are designed to be equal to the upper conductive plate, and in order to cover the part of the upper conductive plate protruding from the screen, the nameplate has In addition to a transparent pressing part that can be used to watch the screen and press the upper conductive plate, a frame-shaped non-transparent printing part that surrounds the screen and is used to print decorative patterns protrudes from the periphery of the pressing part. Because the upper conductive plate covered by this printing part It will not be enabled to have a touch function, so that when the touch device is produced, in addition to increasing the production cost due to the need to increase the size of the upper conductive plate and the lower conductive plate, because the enlarged part does not have a touch function, So it will also cause a waste of resources. However, if the size of the upper conductive plate and the lower conductive plate is directly reduced, and the unactivated parts are omitted, the printing part of the nameplate protruding from the upper conductive plate will be suspended, and the electronic product must be additionally designed for the printing part of the nameplate. Only by embedding and pasting the structure can the nameplate be flat without bending, which makes the use of the touch device more inconvenient.

The conductive cable 8 is clamped and fixed between the first filling block 6 and the nameplate 5. And in order to make the thickness of the conductive cable 8 overlapped between the first filling block 6 and the nameplate 5 so as not to cause the part of the nameplate 5 to bulge upward, the optical adhesive film 101 is provided with a conductive cable. The perforation 102 embedded in the solder joint (not shown) of 8, the double-sided adhesive film 103 used has different thickness designs, that is, the double-sided adhesive film 103 is located in the right area between the first filling block 6 and the conductive cable 8 The thickness of section 104 is relatively thin, while the left section 105 located between the first filling block 6 and nameplate 5 is relatively thick, so that the conductive cable 8 can be embedded in the right section 104 flush with the top surface of the left section 105 In the process, the name plate 5 is evenly pasted on the first filling block 6 . However, during implementation, the lamination and bonding between the upper conductive plate 4 , the name plate 5 , the first filling block 6 and the second filling block 7 are not limited to the above methods.

As shown in Figures 2 to 4, the upper and lower conductive plates 4 and the lower conductive plate 3 have the same length and width, and are transparent for viewing the screen image below it, and the lower conductive plate 3 A first notch 31 is recessed on the right side of the rear end. The conductive cable 8 is electrically connected to the rear end of the lower conductive plate 3, and protrudes backward and to the right from the first gap 31 between the rear end edge of the lower conductive plate 3 and the right side, and can be bent downward. embedded in the first notch 31 and connected to the electronic device. Since the internal structure designs of the upper conductive plate 4 and the lower conductive plate 3 are general techniques and are not the focus of improvement of the present invention, they will not be described in detail.

The nameplate 5 is a flexible thin plate, which has a transparent window portion 51 that is fixed on the top surface of the upper conductive plate 4 and can be pressed to touch the upper conductive plate 4, and a transparent window portion 51 that is attached to the rear end of the upper conductive plate 4 and extends from the window portion. 51 The rear end protrudes backwards over the first printed part 52 on the rear edge of the upper conductive plate 4, and one is attached to the front end of the upper conductive plate 4 and protrudes forward from the front edge of the window portion 51 over the upper conductive plate 4 The second printing portion 53 on the front edge, and two third printing portions 54 protrude from the left and right sides of the window portion 51 and are attached to the top surface of the upper conductive plate 4 respectively. Wherein, the right half of the first printing part 52 is stacked above the conductive cable 8, and the front and rear ends of the third printing part 54 are respectively connected with the second printing part 53 and the first printing part 52, and the third The sides of the printing part 54 are aligned with the sides of the upper conductive plate 4 .

The first filling block 6 extends left and right through the double-sided adhesive film 103 and is pasted and fixed on the first printing part 52 and the bottom surface of the conductive cable 8 , and its bottom surface is aligned with the bottom surface of the lower conductive plate 3 .

In addition, the design of the first notch 31 recessed on the right side of the lower conductive plate 3 allows the conductive cable 8 to be bent downward, and its bent part can be embedded in the first notch 31 correspondingly without protruding the nameplate 5. The side can make the installation of the touch device 2 more convenient.

As shown in Figures 5 and 6, the difference between the second embodiment of the touch device with a large-area nameplate and the first embodiment of the present invention lies in the setting position of the conductive cable 8 and the structure of the first filling block 6 design. For the convenience of description, only the differences between this embodiment and the first embodiment will be described below.

In this embodiment, the lower conductive plate 3 is not provided with a first gap (not shown), and the conductive cable 8 electrically connected to the rear end of the lower conductive plate 3 is designed to protrude backward through the first filling gap. Block 6, and a second notch 61 is recessed on the rear side of the first filling block 6, and the second notch 61 can be used for the conductive cable 8 to be embedded forward when it is bent downward, so as to avoid the bending of the conductive cable 8. The folded part protrudes from the rear edge of the nameplate 5, so that the touch device 2 can be conveniently installed on an electronic device.
