Embodiment

Please consult Fig. 1 earlier to shown in Figure 3, the utility model provides a kind of key device 1 of electronic product, wherein this electronic product can be a digital camera, as shown in the figure, only show a housing 4 and a circuit board 5 of this electronic product, all the other members etc. are not scope and the emphasis that the utility model is asked, so will not limit and be given unnecessary details.This key device 1 is installed on the housing 4, includes a support 10 and most elasticity and is linked to key body 20 on the support 10.

The circuit board 5 of electronic product is provided with most conductive patterns 51, and housing 4 offers most the key holes 41 to being positioned at each conductive pattern 51; Wherein, the inner surface of housing 4 can be equipped with most reference columns 42.

The support 10 of key device 1 can be provided with the location hole 11 corresponding to above-mentioned reference column 42; Key body 20 is to have inside and outside relative press section 21 and touch part 22; As shown in Figure 3, wherein be electroplate with the electrodeposited coating (shown in imaginary line) 30 of tool conductivity on the surface of the touch part 22 of each key body 20.

Above-mentioned support 10 is fixed in the inner surface of housing 4, can penetrate in the corresponding location hole 11 and fixing key device 1 via reference column 42.Each key body 20 of while is located at correspondence and is mounted in those key holes 41, then supply user's pressing keys body 20, and press section 21 is to expose to its pairing key hole 41 to push for the user, and each key body 20 touch part 22 is positioned at this key hole 41, and the electrodeposited coating on the touch part 22 30 is corresponding to the conductive pattern 51 of circuit board 5.Therefore, behind user's pressing keys body 20, can make the electrodeposited coating 30 of touch part 22 contact and reach the purpose that conducts, producing signal, that is when 21 pressurizeds of each press section, can make electrodeposited coating 30 be contacted with conductive pattern 51 on the circuit board 5 with conductive pattern 51 on the circuit board 5.Yet, when key body 20 is pressed, can produce the generation effect of audio prompting user's button by the software of electronic product.

In the utility model, each key body 20 has a base portion 23, and press section 21 is that the outside projection of an end face from base portion 23 forms, and touch part 22 is that inside projection forms from the other end of base portion 23, becomes a column; Yet electrodeposited coating 30 more can be formed on the surface of base portion 23 and press section 21.Further explanation, key device 1 can be by the mode of electroplating, can directly electroplate formation electrodeposited coating 30 on the outer surface within it, that is the surface of support 10 also can whole be electroplate with electrodeposited coating 30, and the press section 21 of key body 20 also more be electroplate with electrodeposited coating 30 (shown in the imaginary line among Fig. 4) with base portion 23, that is the surface of support 10 and key body 20 can integral body be electroplate with electrodeposited coating 30.Certainly cover to prevent to form electrodeposited coating the relevant surfaces position that also can select not need electrodeposited coating before electroplating, therefore after plating, can make electrodeposited coating be formed at the place, desired position, but the most important thing is, need to electroplate and be formed with electrodeposited coating 30 in the touch part 22 of each key body 20, use with circuit board 5 on conductive pattern 51 reach the purpose that conducts.On the other hand, support 10 comprises a rack body 12, is connected with in the elastic arm 13 of rack body 12 and key body 20, can be pushed by elasticity for key body 20 by elastic arm 13.

Via above-mentioned explanation, the utility model is electroplate with the electrodeposited coating 30 of tool conductivity on key body 20, utilize the conductive pattern 51 on the electrodeposited coating 30 turning circuit plates 5, when key body 20 is pressed, can make the conductive pattern 51 of the electrodeposited coating 30 contact turning circuit plates 5 on the touch part 22, thereby the generation signal, so can save the switch (switch) of electronic component, to reach the purpose that reduces cost.So, can add that more the software of electronic product cooperates the generation effect of generation audio prompting user's button, and reach the purpose of prompting.

But, the above only is a preferable possible embodiments of the present utility model, and is non-so promptly limit to claim of the present utility model, so the equivalent structure that uses the utility model specification and graphic content to do such as changes, all in like manner all be contained in the scope of the present utility model, close and give Chen Ming.
