Fig. 1 is that the external touching device of the utility model and mobile phone are used cooperatively schematic diagram；

Fig. 2 is the external touch apparatus structure schematic diagram of the utility model；

Fig. 3 is the utility model membrane keyboard structural schematic diagram.

In the figure, it is marked as 1, mobile phone, 2, conductive sheet, 3, call wire, 31, conducting spring section, 32, conduction straight section, 33, winding Device, 34, membrane keyboard.

Specific embodiment

Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed Thin explanation.

The external touching device of this capacitance plate of the utility model, as shown in Figure 1, including the conduction contacted with capacitive screen of mobile phone Piece 2, conductive sheet 2 are connected to external touching device by call wire 3.Wherein call wire 3 includes the conduction bullet set on 2 one end of conductive sheet It spring section 31 and is made of the conduction straight section 32 that conducting spring section 31 extends to external touching device.It can be by capacitor by such structure Screen leads to external control operation, meets the needs of without directly touching screen operator, while the setting of conducting spring section 31 is convenient for The external touching device is fixed using fixing clamp, on the mobile phone or iPad equipment of applicable different-thickness.

In the utility model, as shown in Fig. 2, conduction straight section 32 is equipped with the coiler for controlling to adjust its length, it can pass through 33 crank of coiler is gone to manually, conducting wire is shortened or lengthened, to satisfy the use demand.

In the utility model, as shown in figure 3, external touching device can be set to the membrane keyboard that a kind of contact surface is arc 34, this arc touch key-press imitates ergonomic designs, using comfortable.

In the utility model, 201 stainless steels are can be used with a thickness of the sheet metal of 0.2-0.5mm in preferred conductive sheet Make, conductive sheet 2 can be set as circular configuration, simultaneously because conductive sheet 2 is frivolous, can be equipped with upward turn at the edge of conductive sheet 2 Side, in order to take.

In the utility model, 3 diameter of call wire is 0.4-0.7mm, and optional nickel coated high-carbon steel wire is made.

Conductive sheet 2 is contacted with capacitive screens when use, and call wire 3 is drawn, and membrane keyboard 34 is touched, due to human body electric field, hand Guidance electricity, user's finger form a coupled capacitor, touch screen response by the external touching device of capacitance plate and working face.This electricity The external touching device of Rong Ping can be used in some special scenes, such as mobile phone games external equipment, testing for electrical equipment, self-shooting bar Deng.

The external touching device of the utility model capacitance plate, structure is simple, use easy to carry small in size, meets without direct The demand of screen operator is touched, it is easy to use, there is stronger practicability and preferable application prospect.

The utility model is exemplarily described above in conjunction with attached drawing, but the utility model be not limited to it is above-mentioned Mode, as long as the improvement or directly application of the various unsubstantialities carried out using the method concept and technical solution of the utility model In other occasions, all fall in the protection scope of the utility model.
