Description
Technical field
The utility model is related to art of keypads, more particularly to it is a kind of it is simple in construction, cost is low, safe and reliable antistatic
Keyboard module structure.
Background technology
Electrostatic is a kind of natural phenomena of objective reality, and caused mode is a variety of, such as contacts, rubs, appliance chamber sensing.
Wherein, triboelectrification and static electricity on human body are two big harm in electronics industry, often result in electric equipment products fluctuation of service,
Even damage.In computor-keyboard field, electrostatic is also so that one of " arch-criminal " that its button is ineffective, function is lost, typically
People can strengthen product antistatic effect using ESD components, but such that cost is too high, product competitiveness in the market
It is not strong enough.
Utility model content
The shortcomings that to overcome prior art, the utility model purpose be to provide it is a kind of it is simple in construction, cost is low, safety can
The keyboard module structure of the antistatic leaned on.
The utility model realized by following technical measures, a kind of keyboard module structure of antistatic, including from up to
Under the button assembly, conductive film and the metal base plate that set gradually, the cabling of the conductive film leading-out terminal is nearby provided with least
One conductive fabric, one end of the conductive fabric are connected with blank space beside the cabling of conductive film leading-out terminal, the conductive fabric it is another
One end is connected with metal base plate, and the metal base plate is connected with the ground wire of keyboard pcb board.
As a kind of preferred embodiment, the conductive film includes upper conductive membrane layer, the interval set gradually from top to bottom
Layer and lower conductive membrane layer, each button that the middle interlayer corresponds to button assembly are equipped with a through hole.
As a kind of preferred embodiment, all cablings side blank space of the conductive film leading-out terminal is equipped with and metal bottom
The conductive fabric of plate connection.
As a kind of preferred embodiment, the metal base plate is provided with conducting foam, the conducting foam and keyboard pcb board
Ground wire connects.
As a kind of preferred embodiment, the metal base plate is iron plate or aluminium sheet.
Electrostatic on conductive film is passed to metal base plate by the utility model by conductive fabric, then is passed to through metal base plate
Pcb board, the earth is finally passed to again, a loop is thusly-formed and exports electrostatic.So as to also can effectively prevent without using ESD components
Only electrostatic, simple in construction, cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
With reference to embodiment and compare accompanying drawing the utility model is described in further detail.
A kind of keyboard module structure of antistatic, with reference to figure 1, including the button assembly 3, conductive set gradually from top to bottom

To be, blank space is equipped with the conductive fabric 4 being connected with metal base plate 1 beside all cablings of the leading-out terminal 21 of conductive film 2.So as to
The release of electrostatic can be accelerated, avoid electrostatic breakdown conductive film 2.
The keyboard module structure of the antistatic of one embodiment, with reference to figure 1, specifically may be used also on the basis of previous technique scheme
To be, metal base plate 1 is provided with conducting foam 5, and conducting foam 5 is connected with the ground wire of keyboard pcb board 6.Certainly, implement at other
In example, it is also possible to which conducting strip, conductive fabric etc. replace conducting foam.
The keyboard module structure of the antistatic of one embodiment, with reference to figure 1, specifically may be used also on the basis of previous technique scheme
To be, metal base plate 1 is iron plate, and cost is low, stable performance.Certainly, metal base plate 1 can also be aluminium in other embodiments
Plate, stainless steel plate etc..
Above is the elaboration carried out to the keyboard module structure of the utility model antistatic, is used to help understand that this practicality is new
Type, but embodiment of the present utility model and be not restricted to the described embodiments, it is any without departing from institute under the utility model principle
Change, modification, replacement, combination, the simplification of work, should be equivalent substitute mode, be included in protection model of the present utility model
Within enclosing.
