Embodiment Construction

[0030] figure 2 is an embodiment of the present invention. The structural feature of this embodiment is that two layers of circuit films (4, 6) are made in the usual way, and the corresponding electronic circuits and upper and lower contacts (10, 12) are coated or printed on the films respectively. An insulating layer is provided between the two circuit films.

[0031] The panel (8) of this embodiment adopts the insulating material with good formability such as rubber, polyethylene and other injection molding. The support base (7) is made of hard plastic, which can be a square plate as shown in the figure, and the cut surface is "U"-shaped, or it can be flat; the support base (7) can be a plate type, or can be designed as a folding . The edge of the panel (8) is bonded to the edge of the support base (7) to be airtight. The bumps on the panel (8) are buttons (9). The upper layer circuit film (4) is attached to the inner wall of the panel (8), and the lower layer circuit ...

Abstract

Disk like or tabulate leak free gas cell is composed of panel of key button made from flexible insulation material and support back plane. Upper layer circuit is coated on inner side of faceplate, and lower circuit is coated on inner side of support back plane. Insulated gas is filled into gas cells. Advantages of the invention are small size, lightweight, windable and portable as well as properties of waterproof, dustproof and low noise.

Description

technical field [0001] The invention relates to an electronic information input device of electronic information equipment. Background technique [0002] Modern electronic information equipment systems all have an indispensable part—input device, such as the keyboard of an electronic computer. The basic structure of the electronic information input device includes an upper and lower circuit film, and the electronic circuits of the circuit and the contacts corresponding to the keys are coated on the film. The signal input is completed through the clutching of the corresponding contacts of the two-layer circuit film. An insulating layer and an elastic self-restoring device are separated between two layers of circuit films. Above the upper circuit film is a panel and various buttons. The bottom of the lower circuit film is a support base plate. [0003] The miniaturization and portability of information technology equipment is the current development direction. For the com...
