Abstract
A portable electronic device key comprises a hard plastic rubber top, a soft rubber substrate and a gasket with certain hardness; wherein the gasket is arranged between the top and the substrate while the upper and the lower surfaces of the gasket are separately bonded with the top and the substrate, the hardness of the top changes the hand feeling of keys, and the gasket increases the hardness of the substrate so as that the comfortable feeling can be got when keys are pressed.
Description
[technical field]
The utility model relates to a kind of portable electron device button, is meant especially a kind ofly to be applied on mobile phone, the notebook computer and the button with preferable feel and operation sense.
[background technology]
Follow the progress of science and technology, many electronic products, universal day by day as mobile phone, computing machine, PDA (personal digital assistant) etc.Early stage electronic product volume is bigger, be provided with that superincumbent button has enough spaces so that the user carries out pressing operation, button generally adopts top and substrate one-body molded, and below button, be provided with the conductive rubber salient point, when being subjected to pushing, conductive salient point contacts and outgoing signal with contact on the circuit board.
Now, compactization become the trend of design of electronic products, for the volume-diminished of electronic product, is easy to carry, and mini product is just being puted forth effort to develop by manufacturer.The electronic product overall volume diminishes and certainly will require to be arranged on also corresponding the dwindling of button above it, how to guarantee when button dwindles, a difficult problem that have conveniently, comfortable pressing operation has become the puzzlement dealer.
At the problems referred to above, China utility model patent CN has provided a kind of Improved key structure (Fig. 1 shows) for No. 2139301, this button comprises plastic cement key body, rubber binding layer and conductive rubber, offers groove in the bottom of plastic cement key body so that the rubber of rubber binding layer infiltrates.Though She Ji button has the hard top like this, feel is preferable, but the undercapacity of soft rubber can produce a kind of unsettled sense when pushing.
[summary of the invention]
The purpose of this utility model is to provide a kind of have preferable feel and operation sense and lower-cost portable electron device button.
The object of the present invention is achieved like this: the utility model portable electron device button comprises hard plastic top, soft rubber substrate and the pad with certain intensity.Wherein, pad is arranged between top and the substrate, and upper and lower two surfaces of pad bond with top and substrate respectively.
Compared with prior art, the invention has the advantages that: the rigid nature at top has been improved the feel of button, and simultaneously pad is strengthened the intensity of substrate, pushes to have comfortable operation sense when strong.
[description of drawings]
Fig. 1 is the cut-open view of existing button
Fig. 2 is a three-dimensional exploded view of the present utility model.
[embodiment]
Please refer to shown in Figure 2ly, the utility model comprises top 10, pad 20 and substrate 30.Wherein top 10 is made by hard plastic, and can be at its surface printing or etching numeric character, so that user's identification and operating.Described hard plastic can be that epoxy resin (Epoxy resin) or acrylate copolymer resins thermoset resins such as (Acrylic copolymer) are formed by injection molding, and this thermoset resin viscosity is between 15000～26000CPS.Pad 20 is a kind of polycarbonate (PC) or sheet metal, and the polycarbonate viscosity is good more than 3CPS, to strengthen the intensity of substrate 30.Substrate 30 is soft silication elastomeric materials, has certain elasticity.The upper and lower surface of pad 20 is bonding by viscose glue and top 10 and substrate 30 respectively.
When top 10 was pressed, pad 20 can conduct to substrate 30 to pressure, made substrate 30 that elastic deformations take place, thus with wiring board (not shown) on contact or termination contact, send control signal.The magnitude range of required pressing force can realize by the thickness of adjusting pad 20 and substrate 30.
Not only has the feel of hard plastic according to the designed button of the utility model, the elasticity that has silication rubber simultaneously, 20 on pad can be avoided the unsettled sense of pushing that existing button causes because of rigidity and elasticity are not enough, can reduce simultaneously top 10 impact to rubber substrate 30 when being pressed, prolong the serviceable life of button.
Claims (5)
