Description
Technical field
The present invention relates to a kind of key, in particular to a kind of key activities contact improves structure.
Background technique
Keyboard is widely used in daily life.
Key, one of the important component as keyboard, height directly influence the height of keyboard, such as
A kind of key switch disclosed in CN204270944U, referring to Fig.1 shown in -1a, key switch is that a kind of pushed using key is driven
Mechanism opens movable contact and stationary contact by on-off and realizes the switch of circuit changing-over, mainly includes upper pedestal 1 ', lower base
2 ', movable contact flat 3 ', fixed touch plate 4 ', briquetting 5 ', spring 6 ' and sound piece 7 ' send out framework 313 ' by pressing briquetting 5 '
Raw elastic deformation, control contact 315 ' is contacted with the contact 41 ' of fixed touch plate 4 ', to realize the Push And Release of key;Nowadays, with
People it is growing to fine needs, frivolous, portable keyboard is increasingly becoming a kind of future trend, but because of active contacting plate
31 ' is higher with the height of movable terminal 32 ', so the whole height of key increases therewith, virtually improves production cost, and
If having shortened the length of stretch section using the improved procedure for directly reducing by 3 ' height of movable contact flat, bending is usually made to live
Larger resistance is generated when movable contact spring 3 ', i.e. framework 313 ' is not susceptible to elastic deformation, cause switching effect it is undesirable, using sense of touch
Uncomfortable situation.
Summary of the invention
The purpose of the present invention is to provide a kind of key activities contacts to improve structure, and improved key height significantly drops
It is low, have the characteristics that it is frivolous, and save production cost, it is comfortable using sense of touch.
To achieve the goals above, technical scheme is as follows:
A kind of key activities contact improvement structure, including upper pedestal, lower base, movable contact flat, fixed touch plate, briquetting and bullet
Spring;Upper pedestal and lower base snap together, and briquetting is slidably mounted in upper pedestal, spring be placed in briquetting and lower base it
Between, movable contact flat and fixed touch plate are separately mounted in upper pedestal, and positioned at the side of briquetting, the movable contact flat connects including activity
Contact and movable terminal, active contacting plate are contacted with movable terminal, it is characterised in that:Active contacting plate includes frame body, first curved
Trisection and the second bending segment;One end of first bending segment connects frame body, and the other end of the first bending segment forms contact and briquetting bullet
Property is touched;Second bending segment one end is connect with contact, and the second bending segment other end forms contact and touches with fixed touch plate elasticity.
Further, first bending segment and the second bending segment are in U-typed.
Further, the height of the movable terminal and the height of active contacting plate are consistent.
Further, the two sides of the briquetting form sliding block, and the inner wall of upper pedestal forms guide-track groove corresponding with sliding block, briquetting
It is slidably mounted in upper pedestal by the cooperation realization of sliding block and guide-track groove.
Further, the middle part of the briquetting forms the guide post of protrusion, and lower base forms guide groove corresponding with guide post,
Guide post is plugged in guide groove.
Further, further include sound piece, the first slot is opened up in the upper pedestal, is equipped with partition, partition in the first slot
Inside planted for movable contact flat, the outside of partition is planted for fixed touch plate;The other side in upper pedestal relative to the first slot
The second slot is opened up, sound piece is plugged in the second slot.
After adopting the above scheme, using the gain effects of two bending structures, show can be by work to movable contact flat by the present invention
The height of movable contact spring is shortened, length of second bending segment equivalent to increase stretch section, can make contact that elastic shape occur
When variable speed moving contact, it will not increase because highly reducing the resistance for causing elastic deformation to be overcome, i.e., active contacting plate is still easy
Bending, does not only reach same switching effect, and does not influence uncomfortable using sense of touch, drops key height significantly
Low, key is whole more frivolous, while reducing production cost.
Below in conjunction with drawings and the specific embodiments, the present invention will be further described.

Specific embodiment
A kind of key activities contact 3 that the present invention discloses improves structure, as shown in figs. 1-7, including upper pedestal 1, lower base
2, movable contact flat 3, fixed touch plate 4, briquetting 5, spring 6 and sound piece 7.
1 two sides of upper pedestal form the fixture block 11 outwardly protruded, and lower base 2 forms the card slot 21 of corresponding fixture block 11, upper pedestal 1
The fastening with lower base 2 is realized by the cooperation of fixture block 11 and card slot 21.
The middle part of upper pedestal 1 opens up a through-hole 12 being embedded in for briquetting 5, and the two sides of briquetting 5 form sliding block 51, upper pedestal 1
Inner wall form corresponding with sliding block 51 guide-track groove 13, briquetting 5 is realized by the cooperation of sliding block 51 and guide-track groove 13 and is slidably installed
In in upper pedestal 1, also, the middle part of briquetting 5 forms the guide post 52 toward 2 direction of lower base protrusion, and upper pedestal 1 is formed and is oriented to
The corresponding guide groove 22 of column 52, guide post 52 are plugged in guide groove 22, meanwhile, spring 6 be placed in briquetting 5 and lower base 2 it
Between, it is socketed in guide post 52;When pressing briquetting 5, briquetting 5 can carry out linear slide and reset in upper pedestal 1, enhancing
Integrally-built stability.
Movable contact flat 3, fixed touch plate 4 and sound piece 7 are mounted in the following manner in upper pedestal 1:Is opened up in upper pedestal 1
One slot 14 is equipped with partition 15 positioned at the side of briquetting 5 in first slot 14, the inside of partition 15 is planted for movable contact flat 3,
It is planted for fixed touch plate 4 in the outside of partition 15;The other side in upper pedestal 1 relative to the first slot 14 opens up the second slot 16,
Sound piece 7 is plugged in the second slot 16.
Fixed touch plate 4 is equipped with conductive contact 41, and movable contact flat 3 includes active contacting plate 31 and movable terminal 32,
Active contacting plate 31 is contacted with conductive movable terminal 32, and active contacting plate 31 includes frame body 311,312 and of the first bending segment
Second bending segment 314, the first bending segment 312 and the second bending segment 314 are in U-typed;One end of first bending segment 312 connects frame body
311, the other end of the first bending segment 312 forms contact 313 and touches with 5 elasticity of briquetting;Second bending segment, 314 one end and contact
313 connections, 314 other end of the second bending segment form contact 315 and touch with 41 elasticity of contact in fixed touch plate 4, the second bending
Length of the section 314 equivalent to increase stretch section will not be because of height when can make contact 313 that elastic deformation band moving contact 315 occur
Degree reduces the resistance for causing elastic deformation to be overcome and increases, i.e., active contacting plate 31 is still pliable;The height of movable terminal 32
Degree is consistent with the height of active contacting plate 31, therefore the height of movable terminal 32 is dropped as the height of active contacting plate 31 reduces
Low, therefore 100 whole height of key decreases.
After adopting the above scheme, the present invention shows and can incite somebody to action to the gain effect of two bending structures of use of movable contact flat 3
The height of movable contact flat 3 is shortened, and does not only reach same switching effect, and do not influence it is uncomfortable using sense of touch, finally
So that 100 height of key is greatly lowered, key 100 is whole more frivolous, while reducing production cost.
The above is only specific embodiments of the present invention, not to the restriction of protection scope of the present invention.All setting according to this case
The equivalent variations that meter thinking is done, each falls within the protection scope of this case.
