Abstract
The utility model relates to a novel film switch structure used for handset press keys, which comprises a key cap, a glue plastic film arranged below the key cap and an elastic sheet arranged below a dome of the glue plastic film, wherein the top of the dome of the glue plastic film is provided with printing points, and the printing points can be arranged at either side of the glue plastic film; when specifically applied, the printing points can be arranged at the side where the glue plastic film and the key cap are matched with each other and can also be arranged at the side where the glue plastic film and the elastic sheet are matched with each other to adapt to the needs of various press key designs; in addition, a release film can also be arranged below the glue plastic film. The utility model has the advantages of simple structure, convenient installation, low cost and convenient production, and can adapt to the needs of the press key designs particularly the handset press keys. By using the utility model the press keys touch comfortable, the accuracy of the press keys is enhanced, and the service life is also prolonged.
Description
Technical field
The utility model relates to a kind of thin film switch structure, particularly a kind of new mobile phone key thin film switch structure.
Background technology
At present, usually adopt following these two kinds of structures at mobile phone key in thin film switch: metal clips is attached to by orientation tool on the plastic film that has layer or passes through the mould heat pressure moulding by the plastic film of full wafer.More than the product produced of two kinds of methods in final assembly because of the tolerance of various parts, make the central point of keycap can depart from the dome of button, this can cause actuation of keys blunt and feel is not good, and useful life is not long.
Summary of the invention
The purpose of this utility model is a kind of new mobile phone key thin film switch structure that provides simple in structure for the deficiency that solves above-mentioned technology, can adapt to various button design needs, raising button accuracy.
In order to achieve the above object, a kind of new mobile phone key thin film switch structure that the utility model is designed, the shell fragment that it comprises the band glue plastic film that keycap, keycap have and is with glue plastic film dome bottom to be provided with, be provided with printing points at band glue plastic film dome top, printing points can be arranged on arbitrary of band glue plastic film, when concrete the application, printing points can be arranged on the one side that band glue plastic film matches with keycap, also can be arranged on the one side that band glue plastic film matches with shell fragment, to adapt to the needs of various button designs.In addition, under band glue plastic film, also can be provided with release film.
A kind of new mobile phone key thin film switch structure that the utility model is designed, simple in structure, easy for installation, cost is low, and is convenient for production, can adapt to the needs, particularly mobile phone key of various button designs.Use the utility model button comfortable feel, and improved the accuracy of button greatly, and prolonged useful life.
Description of drawings
Fig. 1 is embodiment 1 structural representation of the present utility model;
Fig. 2 is embodiment 2 structural representations of the present utility model;
Among the figure 1: printing points, 2: band glue plastic film, 3: release film, 4: shell fragment, 5: keycap.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, a kind of new mobile phone key thin film switch structure that present embodiment is described, it comprises keycap 5, keycap 5 has band glue plastic film 2, band glue plastic film 2 has release film 3, band glue plastic film 2 dome bottoms are provided with the shell fragment 4 that radian with it matches, and the one side that matches with keycap 5 in band glue plastic film dome top is provided with printing points 1.
During use, finger is exerted pressure to keycap 5, and prominent point 1 contact of keycap 5 on shell fragment 4 is directly passed to shell fragment 4 with active force, makes active force directly act on key dome, finishes the one-touch action.
As shown in Figure 2, a kind of new mobile phone key thin film switch structure that present embodiment is described, described printing points is arranged on the one side that band glue plastic film 2 matches with shell fragment 4.
