Embodiment
The present invention be directed to electronic installation and carry out the design of electrostatic discharge protective with conductive shell.On circuit design, utilize the power ground point of electronic installation, the electrical characteristic of collocation electronic component is to finish the approach of leading off of static discharge.Thus, do not produce as yet at conductive shell under the normal condition of static discharge, form open circuit between conductive shell and the power ground point; And when conductive shell produced static discharge, the electrostatic charge of being accumulated on the conductive shell can be led off by the power ground point again immediately.
In addition, on circuit design, the earth point of different functions be can plan usually, power ground point and data-signal earth point etc. are broadly divided into.And because the present invention is in order electrostatic discharge protective to be provided, therefore in design, preferably to select to be used as by the power ground point approach of leading off of static discharge, avoid the electronic component on the static discharge damage electronic installation, being chatted bright earlier at this.
Please refer to Fig. 1, be the block schematic diagram of the embodiment of the electronic installation of tool electro-static discharge protection function of the present invention.As shown in the figure, the electronic installation shown in the present embodiment is to illustrate to be designed to a battery pack, is used for being applied in an application system, and with the power supply source as this application system, it comprises: a conductive shell 1, a circuit board 2 and at least one battery 3.Wherein, conductive shell 1 can directly adopt conductive material (for example metal) to design on actual design, can certainly be to adopt non-conductive material (for example plastics), but form conductive shell 1 by plating or other known technology.
Circuit board 2 is arranged in the conductive shell 1, is used as the circuit substrate of electronic installation.In addition, be formed with a power ground point 200 and a guiding path (ConditionalConducting Path) 21 of having ready conditions on the circuit board 2.Wherein, power ground point 200 belongs to electronic installation set earthed circuit aspect the power supply source of supply.And can understand the battery pack form shown in the present embodiment is to be used as the power supply source of supply with battery 3 (as: lithium battery), so power ground point 200 is negative poles that are electrically connected at battery 3.
Certainly, electronic installation is except the design form of battery pack, affiliated those skilled in the art can understand, the electronic installation that generally is used to provide specific function is in the design of power supply source of supply, also can be divided into the power supply of direct reception battery 3, or adopt different power source conversion elements such as voltage regulator, DC-DC converter, AC/DC converter to receive the power supply of external power source (as: universal serial bus (USB), civil power), operate required electric energy to be converted to electronic installation.And no matter under the design form of which kind of power supply source of supply, power ground point 200 all is directly to be used as the required earthed circuit of power supply source of supply by wiring.
The guiding path 21 of having ready conditions further comprises: an electrostatic discharging element 211 and a conducting element 212.Wherein, an end of electrostatic discharging element 211 is to electrically connect power ground point 200, so forms the circuit form that connects ground in the lump with the power supply source of supply (negative pole of the battery 3 of present embodiment) with electronic installation.On characteristic, when the voltage difference variation at electrostatic discharging element 211 two ends was satisfied with for one pre-conditioned (for example being higher than a voltage quasi position), electrostatic discharging element 211 conductings; And be not content with this when pre-conditioned when the voltage difference at electrostatic discharging element 211 two ends changes, electrostatic discharging element 211 is to be equivalent to a high-impedance component for power ground point 200.In other words, the conducting short circuit phenomenon of electrostatic discharging element 211 is to follow overdrive voltage to take place.Subsidiary one what carry is that above-mentioned electrostatic discharging element 211 pre-conditioned is that the element characteristic by electrostatic discharging element 211 decides.The pre-conditioned specification that is adopted during as for design then is to select different electrostatic discharging element 211 for use according to actual required electrostatic discharge protective, there is no in the present embodiment and is limited.
One fixed connecting end of conducting element 212 is the other ends that electrically connect electrostatic discharging element 211, and a contact jaw of conducting element 212 is that entity electrically contacts conductive shell 1.Thus, allow and have ready conditions guiding path 21 as the conducting path between conductive shell 1 and the power ground point 200.
It should be noted that, if directly conductive shell 1 is connected to the negative pole of battery 3, this design can cause shell conductive shell 1 electronegative, possibly can't meet the safety of product, and causes the problem of fail safe because of producing mobile heating of electric current between different current potential easily.Because heavily fail safe of battery product head so the present invention is being under the prerequisite with the security consideration, proposes aforesaid circuit framework.Circuit characteristic with regard to this circuit framework, electrostatic discharging element 211 is under preset state, just the voltage difference at electrostatic discharging element 211 two ends changes and not to be satisfied with as yet when pre-conditioned, and electrostatic discharging element 211 is open-circuit conditions of formation one high impedance for power ground point 200.Therefore, by the have ready conditions characteristic of conducting of electrostatic discharging element 211, do not produce as yet at conductive shell 1 under the state of static discharge, the guiding path 21 of having ready conditions can effectively intercept conductive shell 1 and directly be connected with power ground point 200, avoids conductive shell 1 to have with power ground and puts the electrode potential that 200 essence equate; And produce the static discharge phenomenon and when satisfying electrostatic discharging element 211 pre-conditioned when conductive shell 1 with the voltage difference of power ground point 200, the guiding path 21 of having ready conditions can be transmitted to power ground point 200 with the electrostatic charge of being accumulated on the conductive shell 1 again effectively, leading off, and reach electrostatic discharge protective by the negative pole of battery 3.
What further specify is that electrostatic discharging element 211 can adopt capacitor, rheostat (Varistor) and transient voltage suppresser, and (Transient Voltage Suppressor TVS) waits an element wherein to design.Right above-mentioned example is not a limitation of the present invention, as long as can carry out the well known elements of conducting as described in the present invention conditionally, all can be the present invention and adopts.
Capacitor is by the two ends metal material, and the centre is again every being formed with megohmite insulant (medium), and therefore can allow between conductive shell 1 and the power ground point 200 is to form open circuit.And medium is that its dielectric strength (Dielectric Strength) is arranged, refer to the maximum voltage value that the unit thickness of this medium can bear, just so-called breakdown voltage (Breakdown Voltage), being scaled unit of account, promptly is the change in voltage (that is aforesaid electrostatic discharging element 211 is pre-conditioned) in the unit interval.So when moment produced static discharge after the conductive shell 1 accumulation electrostatic charge, the voltage that raises can make the electrostatic charge of being accumulated on the conductive shell 1 pass medium suddenly, allows capacitor form the phenomenon of conducting.Electrostatic charge with accumulation on the conductive shell 1 conducts to power ground point 200 thus.
Rheostat (claiming piezo-resistance again), when the voltage of being accepted just often (surpass voltage quasi position), rheostat is to have high impedance and be the good insulation performance body, makes that formation is opened a way between conductive shell 1 and the power ground point 200.But when moment produced static discharge after the conductive shell 1 accumulation electrostatic charge, the voltage that raises can allow rheostat collapse (tool Low ESR) and form conducting suddenly, and a voltage quasi position of its collapse promptly is the pre-conditioned of aforesaid electrostatic discharging element 211.Therefore, the rheostat of conducting this moment can conduct to power ground point 200 with the electrostatic charge of accumulation on the conductive shell 1.
Transient voltage suppresser is a kind of rheostat of tool voltage interdependence, and its principle and rheostat are roughly the same.After voltage is increased to a voltage quasi position (aforesaid electrostatic discharging element 211 pre-conditioned), can cause the impedance of transient voltage suppresser to descend fast, allow the electrostatic charge of accumulation on the conductive shell 1 can be from transient voltage suppresser by being transmitted to power ground end 200.In addition, transient voltage suppresser is to have lower clamping voltage (Clamping Voltage) compared to rheostat, more can promptly electrostatic charge be transmitted to power ground end 200.
On the other hand, 212 of conducting elements are the designs that can for example adopt the organ of one of them or combination in any such as shell fragment, thimble, screw and spring.One end of conducting element 212 is that firm connection (for example welding) circuit board 2 electrically connects with electrostatic discharging element 211, and the contact jaw of conducting element 212 then can electrically contact conductive shell 1.
Certainly, the kind of above-mentioned electrostatic discharging element of giving an example 211 and conducting element 212 is not a limitation of the present invention, and any element with identical characteristics and effect all is to belong to the scope that the present invention protects.
Thus, by the detailed description of the foregoing description, how those skilled in the art implements the present invention if being understood.
Next, in order further to clearly demonstrate the design form of electronic installation of the present invention on the actual hardware framework,, be the framework embodiment decomposing schematic representation of the electronic installation of tool electro-static discharge protection function of the present invention please further with reference to figure 2.
As shown in Figure 2, conductive shell 1 can further comprise a loam cake 11 and a lower cover 12, and circuit board 2 is to be arranged between loam cake 11 and the lower cover 12.And because the circuit board 2 of present embodiment is to be illustrated with upper surface, therefore in the design of conductive shell 1, the part of loam cake 11 is the lids that are designed to conductive material or are electroplate with electric conducting material, and the part of lower cover 12 need not restriction.Right those skilled in the art can be according to of the present invention open, the material of above-mentioned lower cover 12 is designed to conductive material or is electroplate with the lid of electric conducting material, and loam cake 11 then need not restriction, and other equalization changes the scope of implementing also to belong to institute of the present invention desire protection.
Circuit board 2 is to form power ground point 200, an electrostatic discharging element coupling area 201 and a conducting element coupling area 202 by a printed circuit board technology on an insulating surface 20 of circuit board 2.Wherein, electrostatic discharging element coupling area 201 is further to have one first affixed point 2011 and one second affixed point 2012.And the first affixed point 2011 and the second affixed point 2012 are to be electrically connected at power ground point 200 and the affixed point 202 of conducting element respectively by wiring originally.
And then, circuit board 2 is again through electronic component assembling technology, surface mount technology technology (SMTProcess) for example, firmly connect (for example welding) respectively in the first affixed point 2011 and the second affixed point 2012 with two ends, and the fixed connecting end of conducting element 212 firmly is connected in the affixed point 202 of conducting element electrostatic discharging element 211.Right other known method that electrostatic discharging element 211 and conducting element 212 firmly can be connected in addition all can be the present invention and adopts.
The electronic installation of present embodiment is still and utilizes battery 3 to be used as the power supply source of supply to be illustrated.Affiliated technical field technical staff can understand, and battery 3 is to be connected with circuit board 2 by at present known method (for example welding).In addition, because the present invention leads electrostatic charge off by power ground point 200, so only to indicate power ground point 200 among Fig. 2 are negative poles that correspondence couples battery 3, and as for just no longer other sign of the firm affixed point that connects of anodal institute of battery 3 and description.Certainly, if the power supply source of supply of electronic installation is to adopt the power source conversion element to accept external power source, then the power source conversion element just can be finished firm connection by SMT technology.
From the above, architecture design by present embodiment, when electronic installation integral body is finished assembling, loam cake 11 meeting entities electrically contact the contact jaw of conducting element 212, and by conducting element 212 and electrostatic discharging element 211 formed have ready conditions guiding paths 21 and 200 electric connections of power ground point.Thus, with the design of the electronic installation of finishing tool electro-static discharge protection function of the present invention.
Further the actual form with battery pack illustrates, because in the design of battery pack, insulation is very important, if the conductive shell 1 of battery pack is charged, might causes situation of short circuit and causes danger.Therefore, by design of the present invention, when the potential difference of conductive shell 1 and power ground point 200 was higher than the accurate position of predeterminated voltage, the guiding path 21 of having ready conditions can form conducting states, in order to leading electrostatic charge effectively off with power supply earth point 200; When this potential difference was not higher than the accurate position of predeterminated voltage, 21 of the guiding paths of having ready conditions can form open-circuit condition, allowed conductive shell 1 can therefore not have the current potential of power ground point 200.Thus, to strengthen the fail safe of battery pack.
What remark additionally is, because the electronic installation of present embodiment is to use conductive shell 1, therefore when electronic installation has that needs are embedded to be installed in application system (for example: above-mentioned battery pack is to be installed in application system inside in use), then can be further electrically contact with a conductive part (figure does not show) of application system by conductive shell 1, be that another of static discharge led approach off with ground connection the designing for by application system.To this, relevant additional design all is the scope that the present invention can be applied.
At last, please refer to Fig. 3, be the means of defence of the electronic installation of tool electro-static discharge protection function of the present invention, its step comprises: at first, construction one guiding path of having ready conditions is electrically connected between a power ground point of electronic installation and the conductive shell (S301).Wherein, the guiding path of having ready conditions comprises an electrostatic discharging element, and this electrostatic discharging element is that the voltage difference that belongs to when its two ends changes the element of satisfied one pre-conditioned (as: being higher than a voltage quasi position) just understanding conducting.Therefore, voltage difference at conductive shell and power ground point is not higher than under the situation of this voltage quasi position as yet, and electrostatic discharging element can conducting, so for this power ground point, the guiding path of having ready conditions forms the open-circuit condition (S303) of a high impedance, to intercept conductive shell and power ground point.
Then, the guiding path of having ready conditions maintains open-circuit condition, when the voltage difference of conductive shell and power ground point was higher than this voltage quasi position, the guiding path of having ready conditions formed a conducting state (S305), conducts to power ground point (S307) with the electrostatic charge of will be accumulated on the conductive shell.
In step (S307) afterwards, the high voltage that moment produces is after the leading off of electrostatic charge, allow the voltage difference of conductive shell and power ground point be lower than voltage quasi position, the guiding path of therefore having ready conditions reverts to default open-circuit condition (S309) because of the characteristic of electrostatic discharging element.At last, repeated execution of steps (S305) and steps flow chart thereafter thereof are to finish present embodiment at means of defence that static discharge was provided.
