Description

Capacitive touch screen for panel

Technical Field

The utility model relates to the technical field of touch screens, in particular to a capacitive touch screen for a panel.

Background

Capacitive touch screen technology works by using the current induction of the human body. The capacitive touch screen is a four-layer composite glass screen, the inner surface of the glass screen and the interlayer are respectively coated with a layer of ITO, the outermost layer is a thin-layer silica glass protective layer, the interlayer ITO coating is used as a working surface, four electrodes are led out from four corners, and the inner layer ITO is used as a shielding layer to ensure a good working environment. When a finger touches the metal layer, a coupling capacitance is formed between the user and the touch screen surface due to the human body electric field, and the capacitance is a direct conductor for high-frequency current, so that the finger draws a small current from the contact point. This electric current flows from the electrode on the four corners of touch-sensitive screen respectively to the electric current that flows through these four electrodes is in direct proportion with the distance of finger to the four corners, and the controller is through the accurate calculation to these four electric current proportions, obtains the position of touch point, and capacitive touch-sensitive screen uses more on some control panels, and the capacitive touch-sensitive screen that current panel was used mainly adopts the buckle when carrying out the dismouting, and the buckle is once the too big easy break that causes of power to lead to the touch-sensitive screen unable equipment.

Disclosure of Invention

The utility model aims to provide a capacitive touch screen for a panel, which solves the problem that the capacitive touch screen for the panel is assembled and disassembled mainly by adopting a buckle type, and once the buckle type is too strong, the buckle is easy to break, so that the touch screen cannot be assembled.

Technical proposal

In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a capacitive touch screen that panel was used, includes the screen body, the left side overlap joint of the screen body has the back lid, the positive fixedly connected with vertical bar of back lid, the right side fixedly connected with horizontal pole of vertical bar, the constant head tank has been seted up to the lower surface of horizontal pole, the spout has been seted up in the front of the screen body, the interior bottom wall fixedly connected with spring of spout, the top fixedly connected with slider of spring, the positive fixedly connected with bolt of slider, the top and the inside grafting of constant head tank of bolt.

Further, the front fixedly connected with solid fixed ring of the screen body, gu the inside grafting of solid fixed ring has the auxiliary rod, the left end of auxiliary rod and the right side fixed connection of vertical bar.

Further, the right side of the screen body is lapped with a protective plate.

Further, the top fixedly connected with connecting plate of protection shield, the lower surface fixedly connected with fixture block of connecting plate, the draw-in groove has been seted up at the top of screen body, the surface of fixture block and the inside joint of draw-in groove.

The utility model provides a capacitive touch screen for a panel. The beneficial effects are as follows:

1. this capacitive touch screen that panel was used, through mutually supporting between vertical bar, horizontal pole, spout, spring, slider, bolt and the constant head tank, reach and change traditional buckle formula connected mode for dismouting efficiency, it is not fragile simultaneously, mainly adopt buckle formula when having solved the capacitive touch screen that current panel was used and having carried out the dismouting, buckle formula is in case forced too big causes the buckle fracture easily to lead to the touch screen unable problem of assembling.

2. The capacitive touch screen for the panel achieves the purpose of protecting the surface of the screen through mutual matching among the clamping grooves, the clamping blocks, the connecting plates and the protection plates, and avoids damage to the surface of the screen caused by collision of articles.
