Abstract
The utility model relates to an anti-static device for cellphones, which can effectively prevent static on the surface of the cellphone from generating. The utility model has the structure that the position in which static charges easily gathers on a decorative article on the outer surface plate of a cellphone is additionally provided with a static-discharging through hole, wherein the static-discharging through hole is filled with a conductive sponge, and the conductive sponge enables the outer surface plate of the cellphone to be communicated with the ground point of the PCB plate of the cellphone so as to form a static-discharging component; otherwise, the static-discharging component is provided with a narrow long tortuous slender assembly gap in order to prevent the transfer of the static charges. The utility model has the advantages of simple structure, good anti-static effect, etc.
Description
Affiliated technical field
The utility model is the improvement to existing handset structure, particularly the improvement that existing clamshell handset antistatic is designed.
Background technology
Static has constituted the biggest threat to microelectronic component safety.Being extensive use of of particularly miscellaneous wool textile, chemical ﹠ blended fabric, the complexity of mankind's activity expanded range and action, make human body often with on very high electrostatic pressure.When people contact or near sparking of causing of mobile phone metal parts body electrostatic induction is very common.But the induction potential difference Da Wanfu of moment, can directly cause microelectronic component puncture, burn section.Mobile-phone manufacturers to preventing that static from taking into full account, have also made special antistatic ESD electrostatic leakage component design from the selection of sheathing material in complete machine structure at present.So-called ESD electrostatic leakage component design promptly is that important electronic component or position are done the electrostatic isolation protection; spacer assembly is connected with the earth point of self-contained circuit; when discharge generation that electrostatic induction causes; can be easy to that electrostatic charge is introduced earth point and release, thereby the protection electronic component is without prejudice.But at present along with updating to the mobile phone appearance design, the improvement design of many ornamental member has appearred on the outer panels of clamshell handset, metal finishing circle for example, electroplating part or pattern, display window eyeglass on the Dual-band Handy Phone upturning lid outer panels is taked ion plating, the common especially design of metal film in plating, these ornamental design have greatly increased the probability of electrostatic induction and have directly caused the difficulty of antistatic, each decorative element all may become the position of electrostatic leakage, and cause a hidden trouble, how to prevent static damage, become the problem that such mobile phone need be studied.
Summary of the invention
Goal of the invention of the present utility model is the anti-static device that the improvement design to the mobile phone electrostatic-proof function, the particularly decorative element of setting up at existing clamshell handset are taked.
On the outer panels of cellular phone flip for attractive in appearance and ornamental member that set up is more, the back lens surface that the clamshell handset that double screen shows is inlayed on the upturning lid outer panels usually plates layer of metal film by ion plating, and its existence just makes electrostatic transfer become and is more prone to take place.Also just like the ornamental lampshade of setting up on the plate outside, ornamental metal edge frame or plated pattern, the capital increases the probability of static discharge greatly, and cause the damage of LED or other electronic device, for solving above hidden danger, the utility model is especially in clamshell handset upturning lid outer panels, trim component electrostatic charge and the position gathered, set up one and let out the static through hole, conduction sponge bar in the filling in this through hole then, with conduction sponge bar extend make its with outer panels in pcb board on earth point is connected, make conduction sponge bar and decorative element pressure touch new-type ESD electrostatic leakage assembly of formation simultaneously.
Description of drawings
How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes.
Fig. 1 is the upturning lid outer panels schematic diagram of clamshell handset.
Fig. 2 is Figure 1A-A cutaway view.
Fig. 3 is Fig. 2 B partial enlarged drawing
1. upturning lids among the figure, 2. outer panels, 3. glass lens, 4. through hole, 5. conduction sponge bar, the 6.PCB plate, 6A.PCB plate earthing point, 6B.PCB plate earthing point, 7A. shows lampshade, 7B. shows lamp socket, 8. conducts electricity sliver.
Embodiment
In conjunction with the accompanying drawings 1; Fig. 2 as can be seen; the crucial design of the utility model is exactly on the outer panels 2 of upturning lid 1; the leakage path of an electrostatic charge is set corresponding to decorative element; this passage specifically comes filling by conduction sponge bar 5; decorative element can be the display screen glass eyeglass 3 that is embedded on the outer panels; or be contained in decorative lamp assembly on the outer panels; or be arranged on the metal edge frame at any position and electroplate the pattern that is shaped; as long as let out electric through-hole 4 these through holes and be filled with conduction sponge bar 5 or conduction sponge bar 8 to should decorative element having; and it is communicated with the earth point 6A or the earth point 6B of decorative element and pcb board 6; then can very smooth transfer electrostatic charge, play the effect of electronic component in protection LED or the mobile phone.
For display lamp or other like, be provided with outside the above ESD electrostatic leakage assembly apparatus, to prevent that also electrostatic high-pressure from puncturing the fit clearance of logical parts, and electrostatic high-pressure is carried on the electronic devices and components.Matable assembly is designed to many steps, closely spaced assembly relation for this reason, long narrow and the very thin gap that forms, the difficulty of puncture and the resistance value after the puncture have been strengthened, thereby can weaken the generation that electrostatic charge is released effectively, take as shown in Figure 3 to show that lampshade 7A and staged lamp socket 7B match forms the decorative lamp assembly.Its fit clearance can prevent the transfer of static energy storage effectively with regard to long narrow, tortuous and very thin, also is provided with the conduction sponge bar 8 of letting out electricity under lamp socket 7B, then is easy to the earth point 6B that electrostatic charge is transferred on the pcb board 6 is released.
In order further to improve anti-static ability, parts at similar demonstration lamp ﹠ lantern, can be in fit clearance the filling conducting resinl, make conducting resinl in its gap become a part in the ESD electrostatic leakage assembly, then the effect of antistatic can be desirable more, for adapting to the needs of various ornamental member antistatics, can on pcb board 6, a plurality of earth points be set correspondence.
Adopting above architecture advances, can stop issuable static damage when improving the clamshell phone decorative effect, in the improvement design of mobile phone, is unusual important measures.
