Description
Technical field
The utility model relates to a kind of electronic product, relates in particular to a kind of Dustproof waterproff keyboard.
Background technology
Along with the development of electronic technology, as a large amount of in electronic equipments such as computers daily lives that apply to, in work, and control to computer, signal input is main or realize by keyboard, so the importance of keyboard is not accommodating, doubts, but conventional keyboard does not have waterproof now, dustproof characteristic.In the more environment of dust, use, dust very easily enters keyboard, cause switch loose contact, thereby affect the serviceable life of keyboard, and in use, liquid pouring is when keyboard table, liquid can pass through via hole and the gap of surface of keyboard, flow into keyboard, cause short circuit to damage keyboard.Because current keyboard sealing is poor, can have influence on dirigibility and the accuracy of keyboard operation.Upper based on this basis, we have designed a kind of dustproof waterproof keyboard, thereby have made up the defect of conventional keyboard, have promoted practicality and the life-span of keyboard.
Utility model content
The purpose of this utility model is to provide a kind of to be had dustproof and waterproof function and has good protection
The Dustproof waterproff keyboard of characteristic.
For achieving the above object, the utility model provides following technical scheme:
A kind of Dustproof waterproff keyboard, comprise fixedly keycap, panel, mechanical switch, iron plate, printed-wiring board (PWB), base plate, on iron plate, have via hole, between described panel and base plate, be placed with iron plate, mechanical switch, printed-wiring board (PWB), on panel top, place keycap, mechanical switch vertically embeds in iron plate fixing, and the switch pin of described mechanical switch is connected with the pad of printed-wiring board (PWB), forms a functional module group.Panel carries out projection and increases processing in region corresponding to switch shaft, at top, have through hole, facilitate keycap central shaft to match with mechanical switch axle center by panel, panel cut out aperture size is slightly larger than keycap central shaft size, be conducive to keycap press down with springback process in have enough activity spaces, encapsulation process is carried out in other regions of panel, can not have via hole or gap, prevents entering of dust and liquid.
As further program of the utility model: described panel corresponding region projection is increased, top drilling, hole shape can be circle, also can be square other shapes such as grade.
As further program of the utility model: described panel top drilling coordinates with keycap central shaft, retain slight gap.
As further program of the utility model: described iron plate material is that elastic silica gel, printed-wiring board (PWB) material are conducting film.
As further program of the utility model: place elastic silica gel above described conducting film, elastic silica gel presses down the contact short making it on conducting film.
As further program of the utility model: described conducting film is three layers of switch flexible sheet, normality is for disconnecting, and this switch flexible sheet makes upper strata contact and produce elastomer signal with the diaphragm of lower floor by pressing.
As further program of the utility model: described conducting film port is connected with the port of printed circuit board (PCB), realizes the object of electric function.
Compared with prior art, the beneficial effects of the utility model are: product of the present utility model is in the more environment of dust, because Seal Design is processed, dust can not enter interiors of products by via hole and gap, good working environment is provided to inner functional module, thereby has improved the serviceable life of product.When liquid pouring is during in product surface, liquid can flow to panel through keycap, because there is projection in faceplate part region and increases processing, liquid can flow out product surface by the low-lying part of panel, can not enter interiors of products, effectively prevent that liquid from flowing into the inner element short circuit causing, and damages product.And product is after long-term use, dust can be piled up in surface, and user is when clean; detersive spraying is scattered at random; due to the protection of the utility model technology, spraying can only act on product surface, can not enter interiors of products; thereby reached the object of protection product; this uses new structure simple, and good reliability is practical; be convenient to popularize, and there is good dustproof and waterproof effect.
