Description

Improved structure of keys for traditional phones, mobile phones or computers

technical field

The present invention provides a non-press-type keypad for a telephone or a computer with an inductive effect, and enables the keypad to be operated in a touch-type or proximity-type manner, making the operation more simple and easy.

Background technique

At present, we know that the traditional type of telephone, mobile phone or computer (as shown in Figure 1, Figure 2 or Figure 3), its keys can be roughly divided into soft keys and hard keys, but whether it is soft or hard keys There are many types of button, the situation of its button installation structure and the mode of signal triggering. For example, the method shown in FIG. Material and a cushion body 3 with elastic arcs 31, and each elastic arc 31 is corresponding to each button 2, and a conductive part 32 is provided on the inner side of each elastic arc 31, and then the bottom of the cushion 3 A circuit board 4 is provided, and on the circuit board 4 is etched a contact claw 41 which can be triggered as shown in FIG. And make the conductive portion 32 on its inner surface and the contact claw 41 etched on the circuit board 4 to produce conduction effect, so that can generate predetermined signal, to control the dialing of numbers or the control of other functions.

And the operation of such button structure and its control method and steps are as follows:

1. The user stretches out a finger to aim at the button 2 .

2. Move your finger to touch button 2.

3. Press the button 2 down to a certain depth by applying force with your fingers.

4. Retract the fingers to release the pressure of the fingers.

5. Exit key 2.

Therefore, the above-mentioned button 2 operation method not only needs fingers to apply pressure to the button 2, but also needs a certain amount of force, although the force of applying pressure is not large, and if the force of applying pressure and the depth of pressing are not enough, then it cannot be pressed. The conductive part 32 inside the darling pad body 3 touches the contact claw 41 on the circuit board 4, causing the dialing or control signal to fail to be generated; The life of the button 2 is greatly shortened due to the generation of sparks at the moment of conduction; at the same time, the greater the force of pressing the button 2, the greater the friction between the finger and the button 2, so that the surface of the button 2 is printed Numbers, characters, patterns or marks are easily obliterated.

As shown in Figure 6, when the button 2 is embedded in the keyhole 10 of the panel 1, and for the flexible movement of the button 2, the keyhole 10 is usually slightly larger than the button 2, but it also causes the button 2 to be blocked. When the point of force applied by the finger is not located at the center, the button 2 will be tilted, and the conductive part 32 will not be able to contact the contact claws 41 evenly in parallel, resulting in poor contact. Dial or control signals cannot be generated.

Contents of the invention

In order to improve the structure of the keys of the aforementioned telephone or computer and the short lifespan of the operation, the need to use force and the possibility of being unable to effectively touch the defects, the present invention makes the key can be made of a conductive or non-conductive material, and the key is directly connected to the On the circuit board, the user's fingers only need to touch the button lightly or close to the button, so that the button can be sensed and trigger the generation of necessary dialing or control signals, so the operation is not only light and effortless, Moreover, it can greatly reduce the occurrence of obliteration of printed words, patterns or marks on the surface of the key, and the situation that the key cannot be triggered by tilting will not occur at all.

Secondly, a concave part can be set in the middle of the above-mentioned button, or a convex part can be set in the middle of the button, and a concave part can be set in the middle of the convex part, and then a contact can be set in the middle of the concave part, and then the contact can be directly connected to the circuit board. On the circuit, the finger will not accidentally touch the adjacent button and generate an error signal.

In addition, an elastic element can be added under the key to increase the softness and comfort of the key and retain the tactile feeling of traditional operation.
