In order to make the application the technical staff in the technical field more clearly understand the present invention, below in conjunction with accompanying drawing, by specific embodiment, technical solution of the present invention is described in detail.
Embodiment one
Be the structural representation that a button of keyboard of the present invention in the embodiment of the present invention is corresponding with reference to figure 1, Fig. 1.The embodiment of the present invention one provides a kind of keyboard, comprising: insulating base 10, circuit layer 20, a M button 30, a M Flexible Connector 40.
Insulating base 10 can be inorganic insulation plate, the base plate that such as asbestos are made, base plate that glass is made etc., also can be organic insulation plate, such as plastic cement base plate, rubber bottom plate etc., can also the mix insulation base plate 10 that is mixed to form of organic and inorganic material, can also for the insulating base 10 that surface is coated with insulating material and formed, such as in specific implementation process, ensureing the hardness of insulating base 10 for reducing the thickness of insulating base 10 simultaneously, insulating varnish or dielectric ink can be coated with the insulating base 10 formed on the sheet metal that hardness is higher.The thickness of insulating base 10 is relevant to selecting the type of insulating material, does not therefore limit at this.
Circuit layer 20 is formed at insulating base 10 upper surface printing keyboard circuit, concrete, circuit layer 20 is formed with M circuit breakpoint (not shown).Above circuit layer 20, be provided with M button 30, concrete, keypad function is different, and the value of M is also variant, does not therefore limit at this, wherein, and the position one_to_one corresponding of the position of M button 30 and M circuit breakpoint.
In specific implementation process, M button 30 has two set-up modes, the first, each button 30 in M button 30 comprises keycap and scissor, keycap is linked together by scissor and Flexible Connector 40, to connect i-th button 30 and i-th Flexible Connector 40, each button 30 in the second: a M button 30 comprises keycap, M keycap is fixedly installed on a framework, by be fixedly installed the framework of M keycap and keyboard case card and, i is 1 to any positive integer in M, namely i-th can any one in acute pyogenic infection of finger tip M.
M Flexible Connector 40 is fixedly connected on the upper surface of insulating base 10, concrete, the position one_to_one corresponding of M Flexible Connector 40 and M circuit breakpoint.I-th Flexible Connector 40 in M Flexible Connector 40 is arranged between i-th circuit breakpoint in i-th button 30 of M button 30 and M circuit breakpoint, connect i-th button 30 on insulating base 10, M Flexible Connector 40 is preferably flexible silicon Capsule, but does not limit the material of Flexible Connector 40 with this.
As shown in Figure 1, on Flexible Connector 40, correspondence is provided with conductive prominence 401, and conductive prominence 401 can be conductive rubber, one-body molded with other parts of Flexible Connector 40; After conductive prominence 401 can also be the structure based on the one-body molded Flexible Connector 40 as shown in Figure 1 of silica gel, the protruding part coating carbon ink of 401 is to form carbon point in the drawings, thus forms conductive prominence 401.As shown in Figure 1, i-th conductive prominence 401 is when i-th Flexible Connector 40 is in free state, and i-th conductive prominence 401 is in released state with circuit layer 20.
Embodiment two
In order to protect the circuit layer 20 be directly printed on insulating base 10; also comprise heat insulating lamina (not shown), be covered on circuit layer 20, concrete; heat insulating lamina is provided with M breakpoint above the position that M circuit breakpoint is corresponding, is not covered to make M circuit breakpoint by heat insulating lamina.In specific implementation process, heat insulating lamina can be PET film, is set to breakpoint at the position upper thin-film layer at the place of M circuit breakpoint.Also can for printing one deck UV ink at circuit layer 20 upper surface formed, at the position not printing UV ink that M circuit breakpoint is corresponding, above-mentioned two kinds of heat insulating laminas all can ensure that i-th conductive prominence 401 can when being pressed down, contact with the circuit breakpoint of i-th on circuit layer 10, connect i-th circuit breakpoint.
Operation principle below based on the keyboard in above-described embodiment one or embodiment two is described.
Shown in figure 1 and Fig. 2, when pressing i-th button 30, when the elastic force that i-th button 30 overcomes i-th Flexible Connector 40 under external force presses to circuit layer 20, i-th conductive prominence 401 contacts with circuit layer 20, therefore i-th circuit breakpoint in i-th upper M circuit breakpoint of conductive prominence 401 connection makes circuit turn-on, keyboard exports i-th push button signalling of i-th button 30 correspondence, when terminating pressing process, because lose External Force Acting, under the elastic force of i-th Flexible Connector 40, i-th conductive prominence 401 is in released state with i-th circuit breakpoint under the drive of i-th Flexible Connector 40, the end of input of one-touch.
One or more technical schemes in the embodiment of the present application, at least have following technique effect:
1, due to keyboard board is set to insulating base, keyboard circuit is directly printed on circuit layer insulating base being formed keyboard circuit, therefore, reduce the upper circuit thin layer of keyboard in prior art, intermediate isolating thin layer, roll off the production line circuit film layer, thus the thickness of keyboard can be reduced, effectively solve the technical problem that in prior art, keyboard is frivolous not, further reduce keyboard thickness, but make the more frivolous practicality that can not reduce again keyboard of keyboard.
Further, owing to decreasing the upper circuit thin layer of keyboard in prior art, intermediate isolating thin layer, roll off the production line circuit film layer, decreases the assembling parts of keyboard, makes the overall package of keyboard more easily simple.
2, owing to covering heat insulating lamina on circuit layer, such as UV ink, heat insulating lamina is provided with M breakpoint, therefore, it is possible to prevent keyboard circuit oxidized above the position that a described M circuit breakpoint is corresponding simultaneously, also can make circuit layer and external insulation, prevent peripheral operation to the damage of circuit layer.
Although describe the preferred embodiments of the present invention, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the scope of the invention.
