Abstract
The utility model provides a kind of dust protected keyboard of electronic computer, comprise keyboard body and several keyboard caps, described several keyboard caps are nested in keyboard body upper surface, described keyboard cap comprises newel, cylinder plush copper, space, annular protrusion, cavity, interior ring edge and outer shroud edge, wherein, newel is located at keyboard cap bottom center position, and its top is provided with cylinder plush copper, space and annular protrusion from inside to outside successively, described interior ring edge and outer shroud are along being located at keyboard cap periphery below, and newel is isolated by cavity and interior ring edge; Described keyboard body is provided with elastic film wire assembly.The beneficial effects of the utility model are: this product in use, foam-rubber cushion seals the hollow part of keyboard body, stop that most of dust enters into keyboard, set up annular protrusion simultaneously, avoid sensitive part on plastic sheeting because the electric conductivity that the accumulation of dust produces is bad, to guarantee that keyboard normally uses.
Description
Technical field
The utility model relates to field of computer technology, is specifically related to a kind of dust protected keyboard of electronic computer.
Background technology
Computer keyboard is the passage of the control information of word input computing machine, and it develops from english typewriter keyboard, in the time that it occurs on computers the earliest, is the image appearance that is called the parts of " teletype writer " with one.
Keyboard structure: comprise keyboard, cover plate and be embedded in the keycap of each button wherein, this is the part that user mainly contacts.Below upper cover plate, be a rubber film, on the position of each button, there is an elasticity keycap, these parts are exactly the main flexible member of keyboard, and the feel of a keyboard is mainly determined by shape and the material of these parts.Below rubber film, three plies plastic sheetings together, the upper and lower two-layer film wire that is covered with, on the position of each button, there are two contacts, a middle plastic sheeting is not contain any wire, upper and lower two-layer conductive film is cut apart to insulation and come, on the position of key contacts, have circular hole.Like this, under normal circumstances, upper and lower two-layer conductive film is separated by middle layer, can conducting.But after topmost thin film pressurized, will be communicated with lower film at the position of perforate, thereby produce a push button signalling.As can be seen here, present keyboard is actually a kind of tactile keyboard, although profile is far from each other, in fact its ultimate principle is the same with mechanical contact-type keyboard, relies on mechanical conductive contact together with producing push button signalling.
The elastic key hat brim of the keyboard of existing conventional keyboard and above-mentioned patent is along easily entering dust, and after long-term use, in keycap, dust accretions is too much, and dust can cover plastic sheeting, uses electric conductivity bad, and keyboard cannot normally be used.
Utility model content
The technical problems to be solved in the utility model is, overcomes deficiency of the prior art, and a kind of dust protected keyboard of electronic computer is provided.
For technical solution problem, solution of the present utility model is:
A kind of dust protected keyboard of electronic computer is provided, comprise keyboard body and several keyboard caps, described several keyboard caps are nested in keyboard body upper surface, described keyboard cap comprises newel, cylinder plush copper, space, annular protrusion, cavity, interior ring edge and outer shroud edge, wherein, newel is located at keyboard cap bottom center position, and its top is provided with cylinder plush copper, space and annular protrusion from inside to outside successively, described interior ring edge and outer shroud are along being located at keyboard cap periphery below, and newel is isolated by cavity and interior ring edge; Described keyboard body is provided with elastic film wire assembly; Described keyboard cap contacts with the protruding end of elastic film wire assembly by the newel of being located at this keyboard cap bottom center, described to be positioned at the annular protrusion that newel is around provided with mutually nested up and down with the protruding end of elastic film wire assembly, prevents that dust impurity from entering the joint of newel and elastic film wire assembly; Described interior ring edge and outer shroud be along being contacted and be connected with keyboard body by foam-rubber cushion respectively, and interior ring edge and outer shroud edge are all 70 °～80 ° with the angle of surface level.
Compared with prior art, the beneficial effects of the utility model are:
The utility model product in use, foam-rubber cushion seals the hollow part of keyboard body, stop that most of dust enters into keyboard, set up annular protrusion simultaneously, avoid sensitive part (being the joint of newel and elastic film wire assembly) on plastic sheeting because the electric conductivity that the accumulation of dust produces is bad, to guarantee that keyboard normally uses.
