O pads 302 are flowed by input pad 301, the electrostatic in o pads 302 is discharged by release circuit 4.Traditional
It is the terminal tandem resistance or magnetic bead in circuit in antistatic technique, it is therefore desirable to increase component, higher cost, and this Shen
It please be that circuit 2 and release circuit 4 will be protected to connect with pad 3, protection circuit 2 is the conducting wire connected in circuit board body,
And the conducting wire is easy to produce static electricity, pad 3 is the carrier of release electrostatic, and the electrostatic that protection circuit 2 generates can be introduced directly into pad 3,
Then pad 3 exports electrostatic, and release circuit 4 is cathode, or is the conducting wire of ground connection, and pad 3 directly leads derived electrostatic
To release circuit 4, and then it may make the discharge of electrostatic safety.In the present embodiment, the selection of pad 3 is physics pad, cost
It is lower, and pad 3 is without welding on circuit boards, for the lesser situation of circuit board surface components' placement area, Ke Yiyou
The area occupied of the reduction circuit board of effect.
The region that pad 3 is set to circuit board body includes prohibiting cloth region and non-taboo cloth region.In the present embodiment, pad 3
It can be set in the taboo cloth region of circuit board body, such as the one side of the unwelded component of circuit board body, without occupying circuit board
It is welded with the space of component one side, for can effectively reduce first device in increasingly compact handset printed circuit board layout
The occupancy in part region.
Input pad 301 includes the first conductive terminal 3011, and o pads 302 include the second conductive terminal 3012；First
Conductive terminal 3011 is identical with 3012 shape of the second conductive terminal, is cone cell convex block, the first conductive terminal and the second conductive terminal

In the present embodiment, for example, cone cell combined with needle-shaped combined metal block, cone cell with sheet triangle metal block, needle-shaped and sheet
The metal block etc. of triangle combination, this will not be repeated here, and all metal couplings for having tip are covered by the present invention and are limited
Range.
Metal block material combines one in group selected from copper, silver and tin.The material of metal block can carry out conduction, herein
With no restrictions, electric conductivity is better, and the effect of point discharge is better between the first conductive terminal and the second conductive terminal.
Referring to Fig. 2 and Fig. 3, protection circuit 2 includes multiple signal wires.In the present embodiment, such as positive signal line, clock
Signal wire, address signal line, data signal line etc., signal wire is longer or the signal wire of phenomenon easy to produce static electricity can be with
Pad electrical connection.
Each signal wire connects one or more first conducting ends 3011.First conductive terminal of each signal wire connection
3011 quantity is more, and the effect of electric discharge is better, specifically can according to actual needs or experimental result determines that setting first is led
The quantity of electric terminal 3011, correspondingly, the quantity of the second conductive terminal 3012 matches with the first conductive terminal 3011, with
The quantity of the increase of one conductive terminal, 3011 quantity, the second conductive terminal 3012 is consequently increased.
Insulation shell is enclosed with outside pad 3.The material of insulation shell includes plastics, silica gel etc., and this will not be repeated here, weldering
The insulation shell wrapped up outside disk 3 can prevent the electrostatic inside pad 3 from flowing on battery protecting plate, on battery protecting plate its
His circuit generates interference, and damages to circuit, and therefore, insulation shell can be effectively prevented electrostatic and leak, reinforcement pair
The protection of battery protecting plate.
Referring to Fig. 4, the present invention also proposes a kind of antistatic device 102, equipped with battery protecting plate 101 described above.Example
Such as 3C number and notebook protection board, it is not particularly limited herein.
Beneficial effects of the present invention: it is quiet to discharge to do a pad for 101 save the cost of battery protecting plate provided by the invention
