Embodiment
Please refer to Fig. 1, it illustrates is the part-structure schematic diagram according to the keyboard of a kind of tool conductive elastic component of the utility model one preferred embodiment.Keyboard 10 comprises base material 20 and button 30.For convenience of description, following embodiment is to be example explanation with a button, yet does not limit to the claimed scope of the utility model, and the utility model also can be applicable in the keyboard of more buttons.
Base material 20 comprises electrical contact 210 and electrical contact 220 at least, and button 30 comprises button housing 310 and conductive elastic component 320.Conductive elastic component 320 is arranged between button housing 310 and the base material 20, and conductive elastic component 320 comprises elastomer 322, lug boss 324 and the metallic film 326 with groove 328.
Metallic film 326 for example is to be formed at lug boss 324 surfaces with sputter or evaporation mode.And lug boss 324 for example is formed in one with elastomer 322.Moreover lug boss 324 for example is to be bonding on groove 328, or utilizes down to go into part ejection formation (Insert Molding) technology to be formed on the groove 328.
When button 30 was pressed, button housing 310 promptly promoted metallic film 326 and contacts with electrical contact 210 and electrical contact 220, made electrical contact 210 electrically connect through metallic film 326 and electrical contact 220, to send button 30 pairing signals.
Please be simultaneously with reference to Fig. 2 and Fig. 3, Fig. 2 illustrates is first kind of manufacture method flow chart of conductive elastic component, is the schematic diagram of first kind of manufacture method and Fig. 3 illustrates.When elastomer 322 and lug boss 324 are one-body molded, applicable to first kind of manufacture method.First kind of manufacture method comprises the steps: at first to provide the elastomer 322 with groove 328 shown in step 410.Then shown in step 420, form lug boss 324 in groove 328.Shown in step 430, form metallic film 326 at last in lug boss 324 surfaces.Wherein, step 430 for example is to vacuumize earlier, and pattern shade 40 is provided again, and by metal foil membrane formation device 50 metallic film 326 is formed at lug boss 324 surfaces (as shown in Figure 3) with sputter or evaporation mode.
