Embodiment
Please refer to Fig. 2 to Fig. 4, Fig. 2 is the part explosive view of the electronic installation 3 of first embodiment of the invention, Fig. 3 is the vertical view of the flexible circuit board 36 in Fig. 2, wherein key zone 362 not yet bends towards Zou Xian district 360, Fig. 4 is the vertical view of the flexible circuit board 36 in Fig. 2, and wherein Yi Chaozouxian district, key zone 362 360 bends.
As shown in Figure 2, electronic installation 3 comprises cover plate 30, contact panel 32, display panel 34, the flexible circuit board 36 for the button 300 on cover plate 30 and contact panel 32 and the flexible circuit board 38 for display panel 34, wherein flexible circuit board 36 is connected to contact panel 32, and flexible circuit board 38 is connected to display panel 34. In the present embodiment, cover plate 30 can be provided with multiple button 300, such as return key, Home key, multi-functional key etc., depending on practical application. Contact panel 32 is arranged on display panel 34, and cover plate 30 hides on contact panel 32. Generally speaking, electronic installation 3 also comprises housing (not shown), cover plate 30 be combined with housing and in wherein forming accommodating space, in order to necessary assembly when accommodating contact panel 32, display panel 34, flexible circuit board 36,38 and other running, such as power supply unit, communication module, camera model etc.
In actual applications, electronic installation 3 can be smart mobile phone, tablet PC or other electronic installation; Contact panel 32 can be the contact panel of condenser type, resistance-type or other form; Display panel 34 can be the display panel of liquid crystal or other form.
As shown in Figure 3 and Figure 4, flexible circuit board 36 comprises Zou Xian district 360, multiple key zone 362, at least one outlet district 364 and shielding layer 366. The Zou Xian district 360 of flexible circuit board 36 is connected to contact panel 32 so that the treater (not shown) of electronic installation 3 can pass through flexible circuit board 36 and contact panel 32 is carried out relevant control. Key zone 362 is connected to Zou Xian district 360 bently. In the present embodiment, each key zone 362 by a junction 368 bent be connected to Zou Xian district 360, wherein the width W of connection section 368 is between 0.5 millimeter and 10 millimeters, to provide good strength of joint. Outlet district 364 is connected to Zou Xian district 360. In the present embodiment, the clearance G of outlet district 364 between any two key zones 362 is extended. Shielding layer 366 is arranged at Zou Xian district 360 with in outlet district 364. In the present embodiment, shielding layer 366 can be by metallic substance (such as, copper) metallic film made, there is electromagnetism interference (ElectromagneticInterference, and the function of static discharge (ElectrostaticDischarge, ESD) EMI).
During assembling, as long as key zone 362 is bent by operation person towards Zou Xian district 360, key zone 362 is made to be attached in Zou Xian district 360, as shown in Figure 4. After key zone 362 bends towards Zou Xian district 360, shielding layer 366 is between Zou Xian district 360 and key zone 362. Therefore, shielding layer 366 is possible to prevent key zone 362 and interferes with each other with Zou Xian district 360. After electronic installation 3 is assembled, the button 300 on cover plate 30 is corresponding with the key zone 362 of flexible circuit board 36. When user's pressing keys 300, corresponding key zone 362 will be triggered, to perform correlation function.
In the present embodiment, Zou Xian district 360 has multiple first perforate 3600, and each key zone 362 has the 2nd perforate 3620. After key zone 362 bends towards Zou Xian district 360, the first perforate 3600 is corresponding with the 2nd perforate 3620, as shown in Figure 4. In the present embodiment, the 2nd perforate 3620 is more than or equal to the first perforate 3600. Therefore, after key zone 362 bends towards Zou Xian district 360, the 2nd perforate 3620 can not cover the first perforate 3600. Such as, in actual applications, it is possible to the light source (photodiode) of the button 300 on corresponding cover plate 30 is set in electronic installation 3. The light that light source sends is penetrated to button 300 by the first perforate 3600 and the 2nd perforate 3620, so that button 300 sends light, recognizes for user.
Please refer to Fig. 5, Fig. 5 is the vertical view of the flexible circuit board 36' of second embodiment of the invention, and wherein key zone 362 not yet bends towards Zou Xian district 360. The main difference part of flexible circuit board 36' and aforesaid flexible circuit board 36 is, flexible circuit board 36' comprises two outlet districts 364, as shown in Figure 5. Each outlet district 364 respectively clearance G between any two key zones 362 extend. In other words, the clearance G between two key zones 362 is too little, all circuits cannot concentrate on an outlet district 364 when carrying out outlet, so that it may to carry out outlet by the outlet district of two or more.
Therefore, according to technique scheme, the flexible circuit board of the present invention and the electronic installation being equiped with this flexible circuit board at least have following advantage and useful effect: the flexible circuit board of the present invention has the key zone being connected to Zou Xian district bently, during assembling, as long as being bent towards Zou Xian district key zone, key zone is made to be attached in Zou Xian district, therefore, the present invention is not only easy to assembly, does not also need to increase Zou Xian district height, the material of flexible circuit board can also be saved, thus reduce manufacturing cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations. Within the spirit and principles in the present invention all, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
