[embodiment]
Relevant feature of the present utility model and technology contents please refer to following detailed description and accompanying drawing, and accompanying drawing only provides reference and explanation, is not to be used for the utility model is limited.
At first see also Fig. 1, Fig. 1 is the schematic diagram according to the button circuit board of the utility model first embodiment.As shown in Figure 1, button circuit board according to the utility model first embodiment comprises central pad 11, peripheral pads 12 and first lead 15, peripheral pads 12 is arranged on the periphery of central pad 11, and peripheral pads 12 is provided with opening E, and first lead 15 is connected with central pad 11 through opening E.Wherein, the width of opening E is greater than the width of first lead 15, so that first lead 15 and central pad 11 insulation.
Please further referring to Fig. 1, comprise further that according to the button circuit board of the utility model first embodiment second lead, 17, the second leads 17 are connected with peripheral pads.
And, Fig. 1 has illustrated the wire laying mode of the button circuit board with two buttons, as shown in Figure 1, button circuit board more comprises central pad 13, peripheral pads 14, opening F and second lead 16, opening F and opening E are oppositely arranged, and make the lead 15 of winning be connected central pad 11 and central pad 13 with opening F by opening E.Similarly, the width of opening F is greater than the width of first lead 15, so that first lead 15 and central pad 13 insulation.
As shown in Figure 1, in the present embodiment, central pad is that circular pad and peripheral pads are annular pad (promptly as shown in Figure 1),, circular pad is arranged in the annular pad with one heart.But in other embodiment of the present utility model, central pad and peripheral pads also can be other shapes, surround central pad as long as can guarantee peripheral pads to small part, and the two does not contact and gets final product.
Please further referring to Fig. 2, Fig. 2 is the profile according to the button circuit board of the utility model first embodiment.As shown in Figure 2, button circuit board further comprises metal clips 10 and button 19 (not illustrating) in Fig. 1, metal clips 10 is circular-arc, button 19 contacts are arranged at the center of metal clips 10, the edge button of metal clips 10 is located at peripheral pads 12, and the center of metal clips 10 is subjected to external force at button 19 and does the time spent and deformation takes place contact with central pad 11.
Because the edge button of metal clips 10 is located at peripheral pads 12, therefore when user's pressing keys 19, metal clips 10 is subjected to pressed by external force, deformation can take place and recessed, its center is contacted with central pad 11, thereby make central pad 11 be communicated with peripheral pads 12.Therefore, when the user presses this button 19, metal clips 10 can make this central authorities' pad 11 and 12 conductings of annular pad, thereby make the keyboard output signal of keyboard signal output port output can input to the keyboard signal input port, and process chip can detect this button trigger action, and then carries out corresponding button and trigger processing (in hereinafter describing in detail).
