Abstract
The utility model discloses a battery switch button for PCBA, including key cap, the concentric utmost point post that sets up on this key cap, the key cap sets up with utmost point post is integrative, utmost point post includes the conductive part, is used for to connect the connecting portion of conductive part and key cap, the conductive part is cylindricly, and the terminal surface of this conductive part is circular, and this terminal surface is laminated with the location of the key of pressing on the PCBA, be equipped with the conducting resin coating on the terminal surface of conductive part. This button simple structure, utmost point post sideslips when having prevented to press the key cap to the emergence of the sagging phenomenon of button when having avoided pressing.
Description
Technical field
The utility model relates to a kind of button, is specifically related to a kind of cell switch button for PCBA.
Background technology
At present, the cell switch button of PCBA comprises keycap 1 for pressing, arranges with this keycap is concentricPole 2, in the time pressing keycap button is pressed, pole end contacts by key mapping with PCBA's, pole endConducting resinl coating battery is communicated with PCBA, battery is powered to PCBA; In the time that button resets, the utmost pointColumn end separates by key mapping with PCBA's, and battery and PCBA disconnect, the power supply stage casing of battery to PCBA.
As shown in Figure 1, the cross section of existing pole is crosswise, and the end of this pole and PCBA are upper by key mappingContact area little, in the time pressing keycap, pole easily breaks away, cause button sink.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of cell switch button for PCBA,Pole breaks away when preventing pressing key cap, avoids button to sink.
For achieving the above object, the utility model provides following technical scheme:
For a cell switch button of PCBA, comprise keycap, be arranged on the pole on this keycap with one heart,Described keycap and pole are wholely set, and described pole comprises conductive part, for connecting the company of conductive part and keycapMeet portion, described conductive part is cylindric, and the end face of this conductive part is circular, pressing on this end face and PCBAKey mapping laminating, the end face of described conductive part is provided with conducting resinl coating.
Further, the end face of described conductive part is provided with groove, and described conductive part is hollow cylindrical.
Further, described groove is cylindrical groove.
Further, the button plane that the face area of described conductive part is greater than on PCBA amasss.
The beneficial effects of the utility model are:
A kind of cell switch button for PCBA of the present utility model, simple in structure, prevent pressing keyWhen cap, pole breaks away, thus the generation of the sagging phenomenon of button while having avoided pressing.
Brief description of the drawings
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model is carriedDescribe for following accompanying drawing:
Fig. 1 is the structural representation of existing button;
Fig. 2 is structural representation of the present utility model.
Wherein: 1-keycap, 2-pole, 3-installation portion, 4-connection strap, 21-conductive part, 22-connectConnect the end face of portion, 211-groove, 212-conductive part.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
For a cell switch button of PCBA, comprise keycap 1, be arranged on the utmost point on this keycap 1 with one heartPost 2, described keycap 1 and pole 2 are wholely set, and described pole 2 comprises conductive part 21, leads for connectingThe connecting portion 22 of electricity portion 21 and keycap 1, described conductive part 21 is cylindric, and the end face of this conductive part 21 isCircle, fitting by key mapping on this end face and PCBA, the end face 212 of described conductive part is provided with conducting resinlCoating.
A kind of cell switch button for PCBA of the present utility model, simple in structure, the end of its conductive partFace 212 is rounded, and while making to press keycap 1, no matter pressure time is in arbitrary orientation of keycap, and pressure is equalCan be delivered to more uniformly the end face 212 of conductive part, the end face of conductive part 212 with by key mapping laminating more evenly,Tightr, reduce the possibility that pole breaks away, avoid the generation of the sagging phenomenon of button.
As the improvement of such scheme, the end face 212 of described conductive part is provided with groove 211, described conductive part21 are hollow cylindrical. The more columned conductive part 21 of conductive part 21 of this hollow cylindrical is followed and is saved material,And due to processing all there is error, in actual use, its end face compared with circular end surface stressed more equalEven, can further reduce the possibility that pole 2 breaks away, avoid the sagging phenomenon of button to occur.
As the improvement of such scheme, described groove 211 is cylindrical groove 211, now, and the end face of conductive part212 in the form of a ring. Compared with the groove 211 of this cylindrical groove 211 and square groove 211 or other shapes, it is rightThe annular end face of answering is stressed more even compared with the end face of other shapes.
As the improvement of such scheme, end face 212 areas of described conductive part be greater than on PCBA by key mappingArea, can ensure the end 212 of conductive part and fully contacting by key mapping on PCBA, ensures conductive effect.
In the present embodiment, this keycap 1 is provided with the installation portion 3 for keycap 1 is installed, this installation portion 3 and keyBetween cap 1, be provided with the connection strap 4 for being connected and installed portion 3 and keycap 1. Concrete, this installation portion 3 is relativePCBA is fixedly installed, and the material of keycap 1, connection strap 4, installation portion 3, pole 2 is plastics, and keyCap 1, connection strap 4, installation portion 3, pole 2 are wholely set, and can ensure that button is communicated with or disconnection battery and PCBAIn time, responds in time; This connection strap 4 adopts elastomeric material, after button is pressed in the elastic force effect of connection strap 4Under, button can automatically reset; In addition, the list structure of this connection strap 4 is more banded or the structure of its shape moreEasily there is elastic deformation, can reduce button and press the required power of process, when practical operation, only need touch keycap 1.
Finally explanation, above preferred embodiment only in order to the technical solution of the utility model to be described but not limitSystem, although the utility model is described in detail by above preferred embodiment, this areaTechnical staff should be appreciated that and can make various changes to it in the form and details, and not inclined to one sideFrom the utility model claims limited range.
