The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] It should be noted that in the prior art, capacitive touch screen technology works by utilizing the current induction of the human body. The capacitive touch screen is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin glass protective layer. The interlayer ITO coating serves as the working surface. Four electrodes are drawn out from the four corners. The inner layer ITO is a shielding layer to ensure a good working environment. When the finger touches the metal layer, due to the existence of the human body electric field, a coupling capacitor is formed between the user and the touch screen surface. For high-frequency current, the capacitor is a direct conductor, so the finger absorbs a very small current from the contact point. This current flows out from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the position of the touch point by accurately calculating the ratio of these four currents. The above is the working principle of the capacitive touch screen.

Compared with the wiring of the prior art, the conductive spring 400 is not easy to be damaged, and the conductive spring 400 can be directly led out and connected to the circuit board 200 according to the conductive point of the ITO touch screen panel 300, which can reduce the routing on the ITO film and reduce the occupied area.
