The electrostatic prevention structure of the side switch FPC stated.
The utility model embodiment in terms of existing technologies, increases kink on reinforcement steel disc,
And make this kink connect the ground of mainboard, thus avoid in tradition earthing mode, because of manual removal gum
Release liners and problem that conducting resinl planarization cannot be ensured, it is ensured that side switch FPC is adequately grounded；Meanwhile,
Too increase the reliability of side switch FPC ground connection so that side switch FPC will not cause ground connection because of being dismounted for multiple times
Property be deteriorated.
Further, the back side of described main part is coated with the conductive fabric of band gum；Described main part passes through
Described conductive fabric is fixed on housing.On the one hand the antistatic performance of FPC, the opposing party can be further enhanced
Face is good due to gum ground fissility, can support being dismounted for multiple times.
Further, the back side of described main part is coated with gum；Described main part is solid by described gum
It is scheduled on housing.Gum ground fissility is good, can support being dismounted for multiple times.
Further, the back side of described main part is coated with conduction gum；Described main part is led described in passing through
Electricity gum is fixed on housing.The antistatic performance of FPC can be further enhanced.
Further, described kink is screwed on mainboard.Owing to helical locking is relatively reliable,
The most this fixed form advantageously ensures that FPC is adequately grounded.
Further, described kink is fixed on mainboard by housing compacting.When being inconvenient to punch on mainboard
Time, by this fixed form, reinforcement steel disc can be fixed on mainboard, simple to operate facilitate again.
Further, described kink is fixed by welding on mainboard.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing pair
Each embodiment of the present utility model is explained in detail.But, those of ordinary skill in the art can
To understand, in each embodiment of the utility model, in order to make reader be more fully understood that, the application proposes
Many ins and outs.But, even if there is no these ins and outs and kind based on following embodiment
Plant and change and modifications, it is also possible to realize the application each claim technical scheme required for protection.
First embodiment of the present utility model relates to the electrostatic prevention structure of a kind of side switch FPC.Such as Fig. 2 institute
Showing, this electrostatic prevention structure includes flexible PCB 1；One layer of benefit it is coated with on the surface of flexible PCB 1
Strong steel disc 2, reinforcement steel disc 2 includes main part 21 and kink 22 (as shown in Figure 3)；Kink
22 ground connecting mainboard 5.Specifically, the front of main part 21 covers the table at flexible PCB 1
Face, its back side can be fixed on housing 4 by gum, in order to further enhance the anti-of flexible PCB 1
Electrostatic efficiency, in actual applications, can be selected for conduction gum and main part 21 is fixed on (shell on housing 4
The face that body 4 contacts with main part 21 is metal covering).Present embodiment is preferably at the back side of main part 21
Cover the conductive fabric 6 of band gum, make main part 21 be fixed on housing 4 by this conductive fabric 6.This
Way not only improves the anti-static effect further enhancing flexible PCB 1, and owing to the stripping of gum is imitated
Fruit is preferably, it is also possible to support the being dismounted for multiple times of flexible PCB 1 further.
Main part 21 is bent to form kink 22 through extending, and flexible PCB 1 is exactly based on kink 22
Connect the ground of mainboard 5.Specifically, in the present embodiment, kink 22 is provided with screw 221, main
Place corresponding with this screw 221 on plate 5 also is provided with screw 221 (not shown), during production,
Only through two screws 221 and need to lock with screw 7, i.e. can reach and kink 22 is fixed on mainboard 5
On purpose.This fixed form is the safest, advantageously ensures that flexible PCB 1 connects fully
Ground.
Near the screw 221 of mainboard 5, and the part contacted with kink 22 is for leakage copper portion (in figure not
Illustrate), in leakage region, copper portion, the Copper Foil of mainboard 5 exposes so that kink 22 directly contacts with Copper Foil,
Thus reaching the purpose of ground connection antistatic, leakage region, copper portion is the biggest, and the effect preventing Electro-static Driven Comb is the best.
And, this earthing mode not increasing any Anti-static device, also can efficiently reduce the one-tenth of antistatic
This.
Generally speaking, the utility model embodiment is by covering the reinforcement steel on flexible PCB 1
Sheet 2 extension supports the ground to mainboard 5, changes the traditional earthing mode of side switch FPC, both ensure that soft
Property circuit board 1 adequately grounded, enhances the anti-static effect of flexible PCB 1；Too increase flexibility
The reliability of circuit board 1 ground connection so that flexible PCB 1 will cause ground connection property to become because of being dismounted for multiple times
Difference.
Second embodiment of the present utility model relates to the electrostatic prevention structure of a kind of side switch FPC.Second implements
Mode is roughly the same with the first embodiment, is in place of the main distinction: in the first embodiment, curved
Folding part 22 is fixed on mainboard 5 by screw 7；And in novel second embodiment of this enforcement, this is curved
Folding part 22 is fixed on mainboard 5 (as shown in Figure 4) by housing 4 compacting.This fixed form can led
Plate 5 is inconvenient to use of punching, and facilitates the most again.
In actual applications, it is also possible to by arranging pad on kink 22, and mainboard 5 with should
In the part that weld zone is corresponding, weld zone is set, by kink 22 by pad solder in weld zone, from
And make kink 22 be fixed on mainboard 5.
3rd embodiment of the present utility model relates to a kind of electronic equipment, and this electronic equipment can be mobile phone
Deng mobile terminal, this electronic equipment includes the side switch as described in the first embodiment or the second embodiment
The electrostatic prevention structure of FPC.
It will be understood by those skilled in the art that the respective embodiments described above be realize of the present utility model
Specific embodiment, and in actual applications, can to it, various changes can be made in the form and details, and
Without departing from spirit and scope of the present utility model.
