Description
Technical field
The utility model relates to field of remote-control unit, in particular to a kind of electrostatic prevention key.
Background technique
Key is the components of most electronic product indispensabilities, there is very high frequency of use, and existing key is dust-proof antistatic
Ability is poor, and for a long time using thickness, dust can enter inside circuit board from key, so that key is easy failure, not only make key
It is shorter with the service life, and properties of product are unstable.
Utility model content
The purpose of this utility model is to provide a kind of electrostatic prevention keys, have the effect of dustproof static-proof electricity.
To achieve the above object, the utility model uses following technical scheme:
A kind of electrostatic prevention key, for triggering the contact on the wiring board in remote controler, comprising: shell, keycap, flexibility are pressed
Key；The shell offers through-hole, and the hole size and keycap are adapted；Locating slot, institute are equipped at the top of the housing cavity
It states keycap lower edge to extend horizontally outward, is equipped with positioning region at the outer rim of extension upwards, the positioning region is opposite with locating slot
It answers；The flexible keystroke includes press section, support portion and trigger point, and the press section bottom is equipped with trigger point and support portion, institute
Trigger point is stated equipped with conductive coating, the support portion is arranged around trigger point, and the trigger point is made not to be pressed Shi Buyu
Contact contact；The keycap is sheathed on the press section of the flexible keystroke.
Preferably, the keycap outer wall is equipped with the dust ring of protrusion, and the dust ring offsets with housing through-hole inner wall；It is described
The vertical interface of dust ring is right-angled trapezium, and bottom offsets with housing through-hole inner wall thereon, perpendicular to bottom waist positioned at being not orthogonal to bottom
Waist top.
Preferably, the wall at the top of the housing cavity is equipped with antistatic conductive electrocoat.
The preferably described keycap is that duroplasts is made, the dust ring is seal rubber that post forming is bonded with it.
After adopting the above technical scheme, the utility model compared with the background art, has the advantages that
1, the utility model can play placement dust and enter key inside to rise by extending on the outside of keycap lower edge horizontal direction
To dust-proof effect, the effect of dustproof static-proof electricity is strengthened.
2, the utility model is equipped with the dustproof part of protrusion by keycap outer wall, can further function as the work of dustproof static-proof electricity
With.
3, the utility model guarantees key when great dynamics press or press from side by installing keycap additional, and key will not
Inclined side.
Detailed description of the invention
Fig. 1 is the utility model antiwearing keys schematic diagram.
Description of symbols:
1. shell, 11. locating slots, 12. antistatic conductive electrocoat；
2. keycap, 21. dust rings, 22. positioning regions；
3. flexible keystroke, 31. press sections, 32. support portions, 33, trigger point.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.

It is to be based on the orientation or positional relationship shown in the drawings, it is only for convenient for description the utility model and simplify description, without
It is that the device of indication or suggestion the utility model or element must have a particular orientation, therefore should not be understood as practical new to this
The limitation of type.
Embodiment
Cooperate shown in Fig. 1, the use of the new type discloses a kind of electrostatic prevention key, comprising: shell 1, keycap 2 and flexible keystroke
3.Shell 1 offers through-hole, and hole size and keycap 2 are adapted；1 internal chamber wall of shell is equipped with antistatic conductive electrocoat 12,
In the case where not increasing any space, creepage distance can be increased.1 inner cavity top of shell is equipped with locating slot 11, the lower edge of keycap 2
Extend horizontally outward, be equipped with positioning region 22 at the outer rim of extension upwards, positioning region 22 is corresponding with locating slot 11, passes through this
Kind setting can enhance the dustproof static-proof electricity effect of key, and when pressing or pressing energetically from side, will not shift.
Dust ring 21 is additionally provided on the outer wall of keycap 2, dust ring 21 offsets with 1 through-hole wall of shell；Dust ring 21 is indulged
Interface is right-angled trapezium, and bottom offsets with housing through-hole inner wall thereon, perpendicular to bottom waist be located at be not orthogonal to bottom waist top.
By the way that dust ring 21, when can reinforce dust-proof effect, and bounce after its pushing, the dust band that is attached on through-hole wall is arranged
Out.Keycap 2 is made of duroplasts material, and dust ring 21 is the seal rubber that post forming is bonded with it.
Flexible keystroke 3 includes press section 31, support portion 32 and trigger point 33, and 31 bottom of press section is equipped with trigger point 33 and branch
Support part 32, trigger point 33 are equipped with conductive coating, and support portion 32 is arranged around trigger point 33, in the bowl-shape of back-off, make described
Trigger point be not pressed the contact of the contact Shi Buyu；Keycap 2 is sheathed on the press section 31 of the flexible keystroke 3.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
It is subject to the protection scope in claims.
