[0003] In prior art, since capacitive touch screen is in the process of pursuing ultra-thin light, its structure becomes more exquisite and slender, and the connection between each component is more close and sensitive, which leads to a more prominent problem, that is, even the seemingly simple adhesion condition has serious influence on the overall stability of equipment, and further leads to the offset phenomenon of equipment during installation process, and in actual installation operation, this offset problem is particularly tricky, because the installation of capacitive touch screen needs very high precision and stability, and any slight deviation affects the final use effect, when adhesion leads to equipment offset, screen is often difficult to maintain ideal flat state after installation, but will produce different degrees of inclination, this inclination not only affects the appearance beauty of equipment, more importantly, it will directly interfere with the display effect and touch function of screen, for example, image display of screen will appear distortion, color unevenness and other problems, and touch operation will become insensitive or inaccurate due to the inclination of screen, the existence of this condition undoubtedly brings great trouble to the production and installation process of capacitive touch screen, because the unpredictability of inclination problem of screen after installation is increased, so that the yield is greatly reduced, production enterprise has to invest more manpower, material resources and time to carry out quality detection and rework processing, which not only increases production cost, but also prolongs the production cycle of product, and has adverse effect on economic benefit and market competitiveness of enterprise. CONTENT OF UTILITY MODEL

[0004] The utility model aims at solving the shortcomings in prior art, and provides a kind of ultra-thin light capacitive touch screen.

[0005] In order to achieve the above object, the utility model discloses the following technical scheme: a kind of ultra-thin light capacitive touch screen, including outer screen shell, inner screen main body and flat cable strip, the outer screen shell inner wall is equipped with limiting sliding slot, the limiting sliding slot inner wall is slidably connected with convex piece, the convex piece one end is fixed with inner screen main body, the inner screen main body side four corners are all equipped with angle lightening groove.

[0006] Preferably, the angle lightening groove inner wall is fixed with angle reinforcing piece, the outer screen shell inner wall four corners are all fixed with fixed bead, the fixed bead surface is nested with angle reinforcing piece inner wall, in prior art, during the installation process of inner screen main body and outer screen shell, because the fixing difficulty between the two is larger, when installing other line components, inner screen main body is prone to move in vertical direction, this up-down direction movement not only affects the overall stability of equipment, but also leads to the offset between inner screen main body and outer screen shell, more seriously, this offset also causes the damage of angle lightening groove, further reduces yield, increases production cost and production cycle, in view of such problems, the utility model uses the mode of installing angle reinforcing piece to solve, realizes when staff installs inner screen main body and outer screen shell, press inner screen main body into outer screen shell inner wall, when pressing, angle reinforcing piece improves support and pressure sharing to the angle lightening groove of inner screen main body, prevent angle lightening groove damage, simultaneously when angle reinforcing piece reaches fixed bead position, angle reinforcing piece is extruded and releases elastic potential energy and embeds angle reinforcing piece inner wall after being extruded, so that temporarily fixed between components, prevent offset, and give staff or equipment feedback, reach the effect of improving yield.

[0007] Preferably, the limiting sliding groove inner wall is glued and fixed with an auxiliary positioning part, and the top of the auxiliary positioning part is fixed with a composite screen. In the prior art, when the workers install the composite screen, they face a series of severe challenges. Since the covering area of the composite screen is relatively large, it is difficult to accurately control during installation. This uncontrollable feature not only makes the workers feel difficult when installing, but also the composite screen is easy to be unnecessarily blocked due to its large area. This situation makes the workers unable to accurately determine the position and direction of the composite screen, and thus it is difficult to properly install it to the specified position. At the same time, the composite screen is also easy to shake or deviate during installation, which makes the positioning and fixing work of the equipment more complex and difficult. Since the composite screen cannot be stably fixed in the proper position, the glue may accidentally stick to other components during the application or curing process. This accidental glue contamination not only affects the appearance quality of the equipment, but also damages the functionality of the equipment, such as short circuit, poor contact, etc. Ultimately, these problems will greatly reduce the yield of the equipment, increase the production cost and production cycle, and reduce the production efficiency and product quality. In view of such problems, the auxiliary positioning part is adopted to solve the problem, so that when the workers or automatic equipment install the composite screen, the auxiliary positioning part can conveniently position the installation position of the composite screen, and temporarily limit its movement. At the same time, the workers can drop the adhesive in the limiting sliding groove, so as to prevent the adhesive from contaminating other components, and achieve the effect of improving user experience.

[0008] Preferably, the outer shell side is provided with an edge expansion groove, which reduces the influence of temperature on the components and improves the application range of the equipment.

[0009] Preferably, the edge expansion groove inner wall is fixed with an L-shaped reinforcing rib, which improves the service life of the equipment.

[0010] Preferably, one end of the wire arrangement strip is provided with a wide bottom edge, and one end of the wide bottom edge is fixed with the outer shell side. The wide bottom edge improves the fixing area of the components and improves the service life of the equipment.

[0011] Preferably, the limiting sliding groove inner wall is provided with a gluing groove on one side, which increases the contact area of the glue and the components, prevents the glue from overflowing when there is too much glue, and improves the stability of the equipment.

[0012] Beneficial effects:

[0013] 1. In existing technologies, as capacitive touchscreens strive for ultra-thinness and lightweight design, their structures become more intricate and slender, with tighter and more sensitive connections between components. This leads to a significant problem: even seemingly simple adhesion issues can severely impact the overall stability of the device, causing misalignment during installation. This misalignment is particularly challenging in actual installation because capacitive touchscreens require extremely high precision and stability. Any slight deviation affects the final usability. When adhesion causes misalignment, the screen often fails to maintain an ideal flatness after installation, resulting in varying degrees of tilt. This tilt not only affects the device's aesthetics but, more importantly, directly interferes with the screen's display and touch functionality. For example, image distortion and uneven color display may occur, and touch operation will become unresponsive due to the screen's tilt. Insensitivity or inaccuracy undoubtedly pose significant challenges to the production and installation of capacitive touchscreens. The increased unpredictability of screen tilting after installation drastically reduces yield, forcing manufacturers to invest more manpower, resources, and time in quality inspection and rework. This not only increases production costs but also extends the product cycle, negatively impacting the company's economic benefits and market competitiveness. To address this issue, this invention employs a method of installing raised lettering. When installing the inner screen body onto the outer shell, the raised lettering of the inner screen body is aligned with the limiting groove and slid in. The worker can glue the top of the raised lettering as needed, facilitating positioning and installation by both the worker and automated equipment. Furthermore, the combination of the raised lettering and the limiting groove prevents the inner screen body from shifting during subsequent installation, effectively preventing installation failures. Simultaneously, the corner weight-reducing groove lowers the weight of the inner screen body, thus improving the yield rate.

[0014] 2、In the prior art, during the installation of the inner screen body and the outer screen shell, the fixing difficulty between the two is large, so that the inner screen body is easy to move in the vertical direction when the operator installs other line components, the movement in the up-down direction not only affects the overall stability of the equipment, but also causes the offset between the inner screen body and the outer screen shell, and more seriously, the offset also causes the damage at the corner lightening groove, further reduces the yield, increases the production cost and production cycle, in view of such problems, the utility model adopts the mode of installing the corner reinforcing piece to solve the problem, realizes that when the staff installs the inner screen body and the outer screen shell, the inner screen body is pressed into the inner wall of the outer screen shell, the corner reinforcing piece improves the support and pressure sharing to the corner lightening groove of the inner screen body when pressing, prevents the damage at the corner lightening groove, at the same time, when the corner reinforcing piece reaches the fixed bead position, the elastic potential energy of the corner reinforcing piece is released after being extruded and embedded in the inner wall of the corner reinforcing piece, so that the components are temporarily fixed, the offset is prevented, and feedback is given to the staff or the equipment, the yield is improved.

[0015] 3、In the prior art, when the staff installs the composite screen, a series of severe challenges are faced, because the covering area of the composite screen is relatively large, it becomes difficult to accurately control during the installation process, the uncontrollable characteristics not only make the staff feel difficult when installing, but also the composite screen is easy to produce unnecessary shielding because of its large area, which makes the staff unable to accurately judge the position and direction of the composite screen, and further difficult to properly install it to the specified position, at the same time, the composite screen is also easy to shake or offset during the installation process, which makes the positioning and fixing of the equipment more complex and difficult, because the composite screen cannot be stably fixed in the right position, the glue may be accidentally stained on other components during the application or curing process, the accidental glue staining not only affects the appearance quality of the equipment, but also damages the functionality of the equipment, such as short circuit, poor contact, etc., finally, these problems will greatly reduce the yield of the equipment, increase the production cost and production cycle, reduce the production efficiency and product quality, in view of such problems, the utility model adopts the mode of installing the auxiliary positioning piece to solve the problem, realizes that when the staff or the automatic equipment installs the composite screen, the installation position of the composite screen can be conveniently positioned through the auxiliary positioning piece, and the movement is temporarily limited, at the same time, the staff can drop the adhesive in the limiting sliding groove, so that the adhesive staining other components can be prevented, the user experience is improved.

The top of the outer screen shell 1 is provided with a screen sink groove 402. When the staff installs the composite screen 4, they face a series of severe challenges. Because the coverage area of the composite screen 4 is relatively large, it becomes difficult to accurately control during installation. This uncontrollable feature not only makes the staff feel difficult when installing, but also makes the composite screen 4 prone to unnecessary obstruction due to its large area. This situation makes it difficult for the staff to accurately determine the position and direction of the composite screen 4, and thus it is difficult to properly install it to the designated position. At the same time, the composite screen 4 is also prone to shaking or shifting during installation, which makes the positioning and fixing of the device more complex and difficult. Because the composite screen 4 cannot be stably fixed in the right place, the glue may accidentally stick to other components during application or curing. This accidental glue contamination not only affects the appearance quality of the device, but also damages its functionality, such as short circuit, poor contact, etc. Ultimately, these problems will greatly reduce the yield of the device, increase production cost and production cycle, reduce production efficiency and product quality.

The inner wall of the side expansion groove 5 is fixed with an L-shaped reinforcing rib 501, which improves the service life of the device. One end of the wire arrangement strip 101 is provided with a wide bottom edge 6, and one end of the wide bottom edge 6 is fixed to the side of the outer screen shell 1. The wide bottom edge 6 increases the fixing area of the components, thereby improving the service life of the device. The inner wall of the limiting sliding groove 201 is provided with a gluing groove 7 on one side, which increases the contact area of the glue with the components and prevents the glue from overflowing when there is too much glue, thereby improving the stability of the device.
