On mainboard, to form the circuit needed for work, under this huge electronic circuit architecture, electromagnetic interference it is anti-be made for it is important
One of subject, and cause there are many electromagnetic interference factors, electrostatic is exactly one of which factor.
Mainboard can utilize the screw bearing between mainboard and casing in order to which the electrostatic of itself is excluded at present,
In a manner that screw is contacted with casing metal, the electrostatic of generation is excluded, is disposed between these screw bearings and mutually interconnects
The circuit connect, and these circuits are connected with the ground of mainboard.Theoretically, the electrostatic of generation can follow the screw in generic line path and consolidate
Fixed place, is rejected on the ground terminal of casing, but is to belong to equal between the screw bearing that actually these connect with casing
Impedance value between current potential or even these screw bearings is it may be said that very low, so electrostatic may be fixed in these screws
Between run helter-skelter, cause the signal interference problem of mainboard instead.Another way is that metal screws are modified as PLASTIC SCREWS, still
Design requirement is not achieved in PLASTIC SCREWS, torsion, and another lock, which is paid, to be easily broken off, undesirable.Therefore how effectively to exclude quiet on mainboard
Electricity and mutual contact between electronic component and module think deeply subject since interference caused by electrostatic becomes researcher.
Invention content
The purpose of this utility model is to provide a kind of ESD（Electrostatic）Safeguard structure.
In order to achieve the above objectives, the technical solution adopted in the utility model is：
A kind of ESD protection structure, including：Power supply module, PCB main board and pedestal, the power supply module, PCB main board
It fits on the pedestal, the pedestal has the fixed column vertically extended, the power supply module, PCB
Mainboard is supported in the fixed column and passes through fastener and fixes, and is set between the power supply module and the fastener
There is insulation assembly into between-line spacing.
Preferably, the power supply module includes power shell, the L bracket being connected on the power shell, institute
The power shell stated is fixed on by the L bracket in the fixed column, and the insulation assembly is arranged on the L
Between shape stent and the fastener.
It is further preferred that the insulation assembly be coated on insulating trip outside L bracket, be set in it is described
Insulation sleeve outside fastener.
It is further preferred that the section of the insulation sleeve is T-shaped.
It is further preferred that the insulating trip is mylar film.
It is further preferred that the insulation sleeve is plastic cement ejector sleeve.
It is further preferred that the PCB main board is supported in the fixed column, the L bracket is supported on institute
On the PCB main board stated.
It is further preferred that offering the first connecting hole on the PCB main board, is offered in the L bracket
Two connecting holes, the fastener are fixed on by first connecting hole, the second connecting hole in the fixed column.
It is further preferred that the pedestal, fastener, power shell and L bracket are metal material.
Preferably, the fastener is screw.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
The utility model is increasing insulation assembly into between-line spacing to exclude the fastener bearing of electrostatic, completely cuts off fastener
Surface between power supply module contacts, and restores the effect of simple fixed PCB main board structure, when avoiding the electrostatic from excluding, causes letter
The problem of number interference, disturbing factor is reduced, achievees the purpose that preferable electrostatic excludes.
