Abstract
The utility model discloses a metal push-button mobile phone, which comprises a metal push-button, a mobile phone main board and a mobile phone push-button Dome patch positioned between the metal push-button and the mobile phone main board, as well as a metal push-button foot on the metal push-button edge, an orifice at the position on the mobile phone push-button Domes patch corresponding to the metal push-button, wherein dimension of the orifice is smaller than that of the metal push-button foot; and the other side of the orifice is the ground line of the mobile phone main board. The model not only guarantees that the metal push-button foot is not communicated with the main board ground line foot and avoids impact of the leaked voltage upon the user, but also guarantees that the static load on the metal push-button can be released to the air by the orifice, thereby effectively solving the metal push-button static and leakage problem and ensuring the mobile phone use performance and safety.
Description
Technical field
The utility model belongs to the mobile communication terminal technical field, more particularly relates to use the design technology project of metal material as mobile phone key.
Background technology
Mobile phone also becomes the carrier that the user pursues taste and fashion except using as a kind of mobile communication terminal device now.Therefore, in present mobile phones design, increasing mobile phone has adopted metal key-press, compares with traditional organic material button, and metal key-press not only has the metal-like of fashion, and very thin, helps thinner with the mobile phone configuration design.
But mobile phone adopts metal key-press also to have weak point.At first, button is to be touched the most frequent position by human body in the mobile phone, and human body tends to because friction etc. are former thereby have very high-tension electrostatic charge, and metal key-press is the metal plate of a conduction, and therefore, the electrostatic charge on the human body can be transferred on the metal key-press.Electrostatic charge on the metal key-press usually can discharge by the mode to the discharge of the device on the cell phone mainboard, and this charge discharge phenomenon very easily causes the damage of components and parts on the cell phone mainboard.
In order to prevent this discharge impact, in the design of metal key-press, the technical scheme that adopts is to draw a plurality of metal pins from metal keyboard at present, and metal pins linked to each other with the ground wire of cell phone mainboard, like this, electrostatic charge on the metal key-press can directly import the ground wire of mainboard and discharge, and has avoided the electric discharge phenomena to the mainboard device.
Currently usedly there is potential safety hazard equally in the method that metal key-press links to each other with the ground wire of mainboard by metal pins.Because the charger of mobile phone belongs to the AC-DC Switching Power Supply, in the AC-DC Switching Power Supply, must use the Y class electric capacity of cross-over connection to reduce electromagnetic interference (EMI), but this can cause the output of charger to produce tens volts electrical leakage voltage.When the user gave cell-phone charging, the ground wire of cell phone mainboard will have tens volts electrical leakage voltage.If the button in the mobile phone is an organic material, because the casing of mobile phone and button insulate, this electrical leakage voltage can not have influence on the user.But if what use in the mobile phone is metal key-press, and button links to each other with the ground wire of mainboard by metal pins, and then button can have tens volts electrical leakage voltage equally, when the user touches button with hand or face, has tangible electrical sensation.This leakage current can badly influence cellphone subscriber's use, nor can reach the electric leakage standard criterion of mobile phone products, does not meet safety requirements.
Summary of the invention
The purpose of this utility model, just be to solve metal key-press static and the electric leakage problem that exists in the metal current key mobile phone, a kind of handset with metal push button keys that utilizes atmospherical discharges is provided, thereby efficiently solve the static and the electric leakage problem of metal key-press, ensured the serviceability and the safe mass of handset with metal push button keys.
In order to achieve the above object, the utility model comprises metal key-press, cell phone mainboard, and be positioned over mobile phone key dome paster between metal key-press and the cell phone mainboard, further comprise the metal key-press pin on the metal key-press edge, with the aperture of metal key-press pin opposite position, the size of aperture is less than the size of metal key-press pin on the mobile phone key dome paster, and the opposite side of aperture is the ground wire of cell phone mainboard.
Described metal key-press number of pins is 3, and the spacing between metal key-press pin and the cell phone mainboard ground wire is the 0.05-0.1 millimeter.Metal key-press pin material can adopt stainless steel and copper.
Because the size of aperture is less than the metal key-press pin size on the mobile phone key dome paster, thereby guaranteed that the metal key-press pin is not conducted with the ground wire of mainboard, the electrical leakage voltage of charger input just can not be transmitted on the metal key-press, has avoided the influence of electrical leakage voltage to the user; Simultaneously, spacing between metal key-press pin and the cell phone mainboard ground wire is very little, the very thin thickness of button dome paster, if electrostatic charge is arranged on the metal key-press, then the ground wire of metal key-press pin and mainboard will inevitably produce very strong electric field, thereby can carry out atmospherical discharges by aperture,, avoid the damage of static discharge mobile phone with dischargeing of the electrostatic charge safety on the metal key-press.
The utility model solves the static and the electric leakage problem of mobile phone metal key-press, be exactly that requirement should discharge the electrostatic charge on the button with rational approach, the electrical leakage voltage non-conducting that guarantees the charger input has again guaranteed the safe mass of handset with metal push button keys effectively with simple mode to metal key-press.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of button dome paster in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, button dome paster 2 sticks on the cell phone mainboard 3, and metal key-press 1 is fixed on the button dome paster 2.The ingenious just design button of the utility model dome paster 2 solves the static and the electric leakage problem of metal key-press 1.The concrete grammar that adopts is to open aperture 5 with each metal key-press pin 4 corresponding position on button dome paster 2, the size of aperture 5 is less than metal key-press pin 4 sizes, one side of aperture 5 is metal key-press pins 4, and the opposite side of aperture 5 is ground wires of cell phone mainboard 3.
Because the size of aperture 5 is less than metal key-press pin size 4, thereby guaranteed that metal key-press pin 4 is not conducted with the ground wire of mainboard 3, the electrical leakage voltage of charger input just can not be transmitted on the metal key-press 1, has avoided the influence of electrical leakage voltage to the user; Simultaneously, because button dome paster 2 is very thin, if on the metal key-press 1 electrostatic charge is arranged, then will inevitably produce very strong electric field between the ground wire of metal key-press pin 4 and mainboard 3, thereby can carry out atmospherical discharges by aperture 5, with dischargeing of the electrostatic charge safety on the metal key-press 1, avoided the damage of static discharge to components and parts on the cell phone mainboard.
As shown in Figure 2, further described the designed button dome paster 2 of the utility model, button dome paster 2 is made up of paster film 7, button dome6, on paster film 1, have three apertures 5, the position of the position of aperture 5 and metal key-press pin 4 is one to one, and the spacing between metal key-press pin 4 and the mainboard 3 is the 0.05-0.1 millimeter.
Use the utility model, just can efficiently solve the static and the electric leakage problem of metal key-press very simply and easily, ensure the serviceability and the safe mass of mobile phone.
