Abstract
The utility model provides the young sheet of a kind of pot with exhaust, and it comprises substrate, is arranged on the young sheet main body of on-chip pot, and the joint portion of the paste position of substrate and the young sheet main body of pot is provided with steam vent." steam vent " of the present utility model allows " tired gas " Natural excrement, again by resilience natural aspiration, reaches pressure balanced object, thoroughly solve the quality abnormal problem that button is bad.
Description
Technical field
The utility model relates to the young sheet of a kind of pot, particularly relates to the young sheet of pot of band exhaust.
Background technology
The young sheet (metal dome) of current extensive adopted pot is made up of following three parts: 1, dome sheet; 2, PET substrate; 3, exhaust level;
1, dome sheet, dome sheet: popular call in industry, refer to the young sheet main body of the pot of dome, thickness is 0.10 ~ 0.12mm about;
2, PET substrate: containing gum layer, thickness is 0.05 ~ 0.06mm; PET is the abbreviation of English Polyethylene terephthalate, is called for short PET or PETP.Chinese is meant to: poly terephthalic acid class plastics;
3, exhaust level: PET material, containing gum layer, thickness is 0.05 ~ 0.06mm, and exhaust level is bonding with substrate by the film of two-sided gum, and the young sheet main body of pot is also be embedded between adjacent exhaust level by glue to be connected with substrate.As shown in Figure 1:
The young sheet of pot after assembly is connected with PCB in the mode of pasting again, golden finger center superposition on the center of each dome sheet and PCB, form relation one to one, in using, when pressing keys, there is deformation in dome sheet, directly touch on PCB and cause its conducting through finger, and transmit under the effect being subject to external force;
Air discharge duct on the young sheet of pot is the passage of deaeration after the young sheet of pot is squeezed, through by dome sheet local, air directly can not be discharged to the outside space by the tired air stayed in air discharge duct, tired gas (tired gas will be formed in passage, namely the gas in the young sheet of pot is trapped in), cause when reality uses, pressing keys, pot young sheet deformation, sound is clear and legible, but golden finger can not be touched on earth and cannot conducting, the quality abnormal phenomenon of " flicking nonfunctional " namely occurs, and the finished product fraction defective of this type of phenomenon is generally between 2 ~ 3%.
Utility model content
For the young sheet of " air discharge duct " formula pot be widely adopted at present in actual use, the undesirable condition of " the flicking nonfunctional " that produce because tired gas cannot be discharged, do not do the prerequisite of too large adjustment in structure under, consider as the tired gas in young for pot sheet is discharged by how most economical mode.
In order to solve problem in above-mentioned technology, the utility model provides the young sheet of a kind of pot with exhaust, and it comprises substrate, is arranged on the young sheet main body of on-chip pot, and the joint portion of the paste position of substrate and the young sheet main body of pot is provided with steam vent.
As further improvement of the utility model, described steam vent is the one in circle, triangle, square, circular arc.
As further improvement of the utility model, when described steam vent is circular, circular diameter is 1.3 ~ 1.5mm.
As further improvement of the utility model, circular diameter is 1.3mm or 1.4mm or 1.5mm.
As further improvement of the utility model, substrate is arranged the young sheet main body of at least two pots.
The beneficial effects of the utility model are:
" air discharge duct " can only be can be regarded as with regard to its essence is the sidewalk for visually impaired people that the young sheet inside of a transfer pot is stranded gas, " tired gas " really can not be rejected to space outerpace, dome sheet external and internal pressure cannot natural equilibrium, in order to button conducting transmits, often only have and realize by pressing energetically, but this does not meet client about keystroke dynamics: the requirement of 160 ± 30g, so be defined as " flicking nonfunctional " to be considered as defective products; And the principle of " steam vent " allows " tired gas " Natural excrement by pressing exactly, again by resilience natural aspiration, reach pressure balanced object, thoroughly solve the quality abnormal problem that button is bad.
Accompanying drawing explanation
Fig. 1 is the young chip architecture schematic diagram of prior art pot;
Fig. 2 is the young chip architecture schematic diagram of the utility model pot;
Fig. 3 is the utility model pot young sheet side structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The utility model is applicable to all button electronic product being switch triggering conduction mode with the young sheet (metal dome) of pot.
As shown in Figure 2, the young sheet of a kind of pot with exhaust, it comprises substrate to structure structure, is arranged on on-chip several pot of young sheet main body 100, and the number of the young sheet main body of pot is determined according to the actual requirements.
The joint portion of the paste position of substrate and the young sheet main body of pot is provided with steam vent 200.Described steam vent is the one in circle, triangle, square, circular arc, also can be other shapes.When described steam vent is circular, circular diameter is 1.3 ~ 1.5mm.Such as: circular diameter is 1.3mm or 1.4mm or 1.5mm.
The most direct method for exhausting of one is achieved in the young sheet of pot, " air discharge duct " be about to originally for being vented is closed, significantly reduce the processing cost of PET substrate fluting, directly go out in the joint portion of the paste position of PET substrate and dome " steam vent " of ∮ 1.3 ~ 1.5mm, after dome sheet is stressed, in original die cavity, " tired gas " will be got rid of from steam vent, after unclamping button, dome sheet recoils to home position naturally, extraneous air and enter in the die cavity of dome by " steam vent ", realize the natural equilibrium of dome sheet die cavity external and internal pressure, eliminate " flicking nonfunctional " phenomenon.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
Claims (5)
