Abstract

The utility model discloses a dust-proof electronic computer keyboard device, and relates to the technical field of computers. The dust-proof electronic computer keyboard device comprises a keyboard body, and keyboard caps arranged on the keyboard body, wherein a round through hole is formed in the mounting position of each keyboard cap on the keyboard body, an elastic thin film wire assembly is installed on the inner side of each round through hole, and a center column is arranged in the center below each keyboard cap; the outer side of each round through hole in the keyboard body is respectively provided with an inner side groove and an outer side groove; an inner edge is arranged below each keyboard cap, each inner edge is arranged around the corresponding center column, and an outer edge is arranged below the circumference of each keyboard cap; all the center columns are arranged in the round through holes, the inner edges are arranged in the inner side grooves, the outer edges are arranged in the outer side grooves, and a sponge mat is further arranged at the bottom of each inner side groove. The dust-proof electronic computer keyboard device solves the problems that dust can enter the edges of elastic keyboard caps of an existing keyboard easily, dust accumulated in the keyboard caps is too much after the keyboard caps are used for a long time, elastic thin films can be covered with dust, electrical conductivity is poor, and the keyboard can not be normally used.

Description

A kind of dust protected keyboard of electronic computer

Technical field

The utility model relates to field of computer technology, is specifically related to the improvement structure of computer keyboard.

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.

Chinese patent literature ZL92216253.0 discloses a kind of key board unit that relates to robot calculator, this device " is made up of base key and function key; the base key of lining up 26 English alphabet keys that three row ten are listed as and four punctuation mark key compositions is grooved and arranges; middle a line is positioned at bottom land; forward and backward two row lay respectively on the antetheca and rear wall of groove; between the two ends of groove and each row, be provided with crosspiece ", and the keyboard of this patent is easy to use, and can improve the serviceable life of keyboard.

But the elastic key hat brim of the keyboard of existing conventional keyboard and above-mentioned patent is along easily entering dust, 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 utility model provides a kind of dust protected keyboard of electronic computer, the utility model has solved the elastic key hat brim of existing keyboard along easily entering dust, after long-term use, in keycap, dust accretions is too much, dust can cover plastic sheeting, make electric conductivity bad, the problem that keyboard cannot normally use.

For addressing the above problem, the utility model adopts following technical scheme: a kind of dust protected keyboard of electronic computer, comprise keyboard body 1 and be arranged at keyboard body 1 keyboard cap 2 above, on keyboard body 1, the installation site of each keyboard cap 2 is provided with a manhole 4, manhole 4 inner sides are provided with elastic film wire assembly 3, and keyboard cap 2 below centre bit is equipped with a newel 8; On keyboard body 1, each manhole 4 outsides are respectively arranged with inboard groove 7 and outside groove 6, and inboard groove 7 around arranges around manhole 4, and outside groove 6 around arranges around inboard groove 7; Below keyboard cap 2, be provided with interiorly along 9, interiorly around arrange along 9 around newel 8, below keyboard cap 2 peripheries, have outer 10; Newel 8 is arranged in manhole 4, is interiorly arranged in inboard groove 7 along 9, and outer 10 is arranged in the groove 6 of outside, is also provided with foam-rubber cushion 5 in inboard groove 7 bottoms.

The utility model difference with the prior art is to be provided with inboard groove on keyboard body, is provided with interior edge below keyboard cap, is also provided with foam-rubber cushion in inboard groove.In use, foam-rubber cushion, by the sealing around of the manhole of keyboard body, prevents that dust from entering into keyboard, avoids plastic sheeting because the electric conductivity that the accumulation of dust produces is bad, guarantees that keyboard normally uses.Owing to being provided with foam-rubber cushion, so keyboard feel is softer.The utlity model has keyboard good hand touch, long service life, is convenient to clear up the advantages such as dust.
