Abstract
The utility model provides a reinforcement notebook computer water-proof keyboard, belonging to the computer technical field, comprising a keyboard panel, a PCB board, a keyboard film and a keyboard pressure plate, a positioning column arranged on the keyboard film, a positioning hole corresponding with the positioning column on the PCB board, wherein the PCB board is tightly connected with the keyboard panel by a bolt and the keyboard pressure plate stably presses the convex edge of the keyboard film on the keyboard panel and the clearance between the keyboard pressure plate, the keyboard film and the keyboard panel is filled and sealed by the seal material. Compared with the prior technology, the reinforcement notebook computer water-proof keyboard has features of reasonable design, simple structure and convenient use, low cost, wide application use, anti-shaking, high water-proof performance and no water inlet after long time soakage.
Description
Technical field
The utility model relates to field of computer technology, a kind of specifically night-viewable reinforced notebook computer waterproff keyboard.
Background technology
The high performance reinforced notebook computer of the market demand, to put drench with rain and the electromagnetic compatibility requirement relatively harsh, and one of the emphasis of rainproof and EMC Design, processing part---keyboard because position and technical reason, the emphasis that becomes design is considered object.If keyboard structure does not adopt suitable manner, rainproof and EMC performance will be had a greatly reduced quality.And owing to use under the particular surroundings, it is visual that keyboard must satisfy night.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, but the night-viewable reinforced notebook computer waterproff keyboard that provides a kind of with low cost, applied widely, anti-vibration, water resistance high long period of soaking not to intake.
The technical solution of the utility model realizes in the following manner, this a kind of reinforced notebook computer waterproff keyboard, its structure comprises key panel, pcb board, keyboard membrane, described keyboard membrane is provided with reference column, pcb board is provided with the pilot hole corresponding with reference column, pcb board also is fastenedly connected on key panel by screw, its structure also comprises the keyboard pressing plate, firmly by being pressed on the key panel, sealing is then filled by encapsulant in the space between keyboard pressing plate, keyboard membrane, the key panel to described keyboard pressing plate with the cocked bead of keyboard membrane.
Each rectangle button of keyboard membrane is provided with light-transmissive film, and described pcb board is provided with and the corresponding light emitting diode of light-transmissive film.
Key panel is provided with the filtering ballast resistor that is connected with pcb board.
Described keyboard membrane adopts rubber to make.
The beneficial effect that the utility model is compared with prior art produced is:
A kind of reinforced notebook computer waterproff keyboard of the present utility model is realized waterproof by structural design, the edge of keyboard membrane protrudes and presses press fit by the keyboard pressing plate, between keyboard pressing plate, keyboard membrane, key panel, interspace and then fill sealing by encapsulant, the keyboard pressing plate embeds simultaneously the rubber keyboard membrane with keyboard and puts in order together with pcb board is sticking, both played waterproof action, prevented effectively again that Yin Wendu from raising and the bulging of generation.Pcb board is transferred to the filtering ballast resistor, and the PCB signal arrives single-chip microcomputer wherein, can be general on any chipless mainboard, can reach general and standardized effect for the similar type of product line; Characteristics such as cost is low, applied widely, but the anti-vibration long period of soaking is not intake that the utility model also has.
