(end of sparking electrode 300)

As mentioned above, in the end of sparking electrode 300, be installed with for tangling ring-type terminal 301(Fig. 6, Figure 21 of spring 400), by spring 400 stretch-draw and not sagging.As shown in figure 21, by utilizing the method or utilize by the electric current applying the means of spot welds of terminal 301 meltings etc. of riveting tightly of clamping by terminal 301 that the after-applied pressure of electric wire 303 of sparking electrode 300 carries out, as illustrated in fig. 6 terminal 301 is engaged or kept with electric wire 303.In addition, sparking electrode 300, via left middle boxes 600 or right middle boxes 500, as shown in Fig. 6, Figure 14, often turns back once, increases by a line, turns back altogether repeatedly, while turning back, by return portion 680 supportings of left middle boxes 600 and right middle boxes 500.

The material of the electric wire 303 of sparking electrode 300, in order to there is strong hot strength, with the filament of bulb similarly, adopt tungsten (element mark: W) more.In addition, the material of terminal 301, considers from versatility, adopts stainless steel more.Wherein, most using the most general SUS304 as materials'use.Rivet tightly method or the spot welding etc. of electric wire 303 and terminal 301 use are fixing, to use the stretch-draw such as spring also not disconnect.But, because the potential difference of tungsten and SUS304 is more than+0.36 volt, so, when high humidity environment, special accelerator, do the used time, may produce Metal Contact corrosion not of the same race.In the combination of this material, because tungsten side is electronegative potential (negative potential), so while having produced Metal Contact corrosion not of the same race, tungsten side forms WO ₄( ^2-) etc. oxide and dissolving, finally break and lose function.In addition, due to WO ₄( ^2-) solubility very large, so, be dissolved in the moisture that is attached to electric wire 303 surfaces, the gas current on electric wire 303 surfaces increases (conductance is increased), has accelerated the corrosion of tungsten.

For this reason, in the sparking electrode 300 of present embodiment, the material of terminal 301 adopts tin (element mark: Sn), nickel (element mark: Ni) or electroplating surfaces with tin, the nickel plating of the terminal 301 of making at stainless steel etc.Like this, during with the terminal 301 of tin or zinc-plated making, the intermetallic potential difference not of the same race of tungsten and terminal 301, narrows down to-0.11 volt from+0.36 volt.In addition, while making terminal 301 with nickel or nickel plating, potential difference narrows down to-0.01 volt.Which kind of situation no matter, potential difference all reduces a lot, becomes the current potential that is not easy very much to produce corrosion.In addition, because terminal 301 sides are electronegative potential (negative potentials), so terminal 301 becomes sacrificial electrode, tungsten side can not corroded.Because the water solubility of the oxide of tin, nickel is little, so, even if also can not promote corrosion under the condition coexisting at environmental factor, moisture.With tungsten, make electric wire 303, with tin, nickel, tin metal, nickel-plated metal, make terminal 301, can reduce the probability of broken string, can use relievedly for a long time sparking electrode 300.

In addition, in the sparking electrode 300 of present embodiment, as shown in figure 21, adopt inner face adhesion type flexible pipe, with flexible pipe 302, connect airtight with the whole junction surface of tungsten and terminal 301 and by its covering.Inner face adhesion type flexible pipe is the inside and outside two-layer structure with outer and internal layer, and for example, skin is made by flexible polyolefins resin etc., and internal layer has fusing property of heat bond layer.From the viewpoint of gas current inhibition, preferably do not adopt vinyl chloride etc. to sneak into the material of ion component.In addition, by adopting, shrink more than 60% heat-shrinkage material 100 ℃ time, can make flexible pipe 302 connect airtight fixing.In the position that covers the junction surface of tungsten and terminal 301, heat, flexible pipe 302 is fixing.By making the joint minister of Length Ratio tungsten and the terminal 301 of flexible pipe 302, can with flexible pipe 302, cover junction surface effectively.

The internal layer of flexible pipe 302 adopts the bonding agent that has mixed the waterproof ingredients such as silicone, epoxy, can prevent from entering as the moisture of the accelerator of corrosion etc., so corrosion resistance is very strong.Because internal layer adopts bonding agent, so, even if electric wire 303 starts corrosion and will depart from from terminal 301, by the effect of bonding agent, also can not misplace, can not break and depart from, can chronically electric wire 303 be remained on to the assigned position of terminal 301.

In addition, by covering terminal 301 with flexible pipe 302, when assembling, hold flexible pipe 302, can easily electric wire 303 be assembled on device.In addition, near the terminal 301 connecting with rivet tightly or spot welding etc., the bending strength of electric wire 303 is low, towards any direction bending or torsion etc., easily breaks.But, by covering terminal 301 with flexible pipe 302, can improve bending strength, even electric wire 303 can not broken towards the random bending of any direction yet.

When flexible pipe 302 is not inner face adhesion type, although there is no waterproof action, bending strength is improved.At this moment, similarly, adopt heat-shrinkage material, utilize thermal contraction, width is more fixing than much larger terminal 301 sides of electric wire 303 and flexible pipe 302.Although also can be by both thermal contractions,, by not making electric wire 303 side thermal contractions, a side does not form stiff end, can easily obtain the effect of improving of bending strength.

As mentioned above, electric wire 303 adopts tungsten, and terminal 301 employing tin or nickel or tin metal, nickel-plated metal, cover terminals 301 with flexible pipe 302.Such structure, can reduce the probability of sparking electrode 300 interrupt lines, can use relievedly for a long time sparking electrode 300.

(to material of electrode 700 etc.)

The metals such as electrode 700 use stainless steels are formed.In addition, also can adopt and contain carbon etc. and resistance value is low to moderate 10 ⁴the electroconductive resin of Ω/cm left and right.To the connection such as weld, rivet tightly of electrode 700 use, or via the low-pressure side connecting portion 710(Fig. 4 being integrally formed) connect ground wire (GND).To electrode 700, be that a plurality of flat boards of making are respectively configured abreast, it is connected with metallic plate etc. respectively, still, need a plurality of fixed parts, and assemble time-consuming.Therefore,, to electrode 700, especially want to be made into when little and thin or wish that production is good, while can qurer making, preferably use a part (parts) to form.Electroconductive resin exists imperfect earth, problem that price is high, so, preferably use metal (metallic plate) to make.

(structure to electrode 700)

To electrode 700, as shown in Figure 8, by flat part 731, band portion 732 and connecting portion 733, formed.As shown in Figure 8, flat part 731 is the parts of surrounding with dotted line 999, is the parts of surrounding with dotted line 998 with portion 732, and connecting portion 733 is the parts of surrounding with double dot dash line 997.Band portion 732, be for clear and definite and Figure 10 (aftermentioned) to the different and record of electrode, be actually a part for flat part 731.To electrode 700, as shown in Figure 8, be that the connecting portion 733 a plurality of flat parts 731 being connected at longitudinal direction by the left and right directions both sides at flat part 731 forms.That is, flat part 731 is strips of arranging substantially in parallel, and is writing board shape.Connecting portion 733 consists of the 1st connecting portion 733R and the 2nd connecting portion 733L.The 1st connecting portion 733R interconnects the square end portion in the elongate in shape of a plurality of flat parts.The 2nd connecting portion 733L interconnects the opposing party end in the elongate in shape of a plurality of flat parts.The 1st connecting portion 733R and the 2nd connecting portion 733L are referred to as to connecting portion 733.

The 1st connecting portion 733R has the 1st protuberance 735 of each flat part 731 and the 1st brace 707 between each adjacent flat board 731.The 1st protuberance 735, the square end subordinate side from the elongate in shape of each flat part 731, outstanding towards length direction.The 1st brace 707, orientation 742(Fig. 8 among each other, that a plurality of flat parts are arranged in order from adjacent flat board 731) upper end of the 1st protuberance 735 of side in front of, is connected with the lower end of the 1st protuberance 735 in adjacent flat board 731.The 2nd connecting portion 733L also with the 1st connecting portion 733R similarly, there is the 2nd protuberance 736 and the 2nd brace 708.

Figure 12 (a) and (b) are all the sections that are equivalent to C-C section in Fig. 8.

As shown in Figure 12 (b), at least one the 1st brace 707 has kink 741.This kink 741, from the upper end of the 1st protuberance 735, in the way being connected, protrudes towards lower side in the lower end with adjacent the 1st protuberance 735.Similarly, at least one the 2nd brace 708, also has towards the protruding kink 741 of lower side.Figure 12 (a) represents not have the situation of kink 741.Compare with Figure 12 (a), as shown in Figure 12 (b), sparking electrode 300 and the distance of connecting portion 733 are zoomed out, can avoid paradoxical discharge between sparking electrode 300 and connecting portion 733 and unnecessary electric discharge, can form stable electric discharge, electric field.Although the structure of Figure 12 (b) is preferred, also can adopt the structure of Figure 12 (a).

As shown in Figure 12 (b), the connecting portion 733 to electrode 700, in section, has towards the protruding top kink 751 of upper box 200 sides (upper side) with towards the protruding kink 741 of lower side.

Shown in Figure 10, before flat part 931(is corresponding with flat part 731) in the structure that cuts from larger plate, exist the 932(Figure 11 of band portion).This is to cut the rear residual part of flat part 931 from metallic plate with portion 932, at longitudinal direction, is connected with flat part 931, corresponding with connecting portion 733 with connecting portion 933(in the horizontal direction) be connected.

Figure 11 (a) is the D-D section (central portion) in Figure 10.Figure 11 (b) is the side view (representing connecting portion 933) of seeing from the C direction of Figure 10.The direction 901 that has represented wind in Figure 11 (a).

Band portion 932 before, as shown in figure 11, forms wall with respect to the inflow angle of wind, so, produce the large pressure loss, the power consumption of air conditioner is increased.From the viewpoint of reducing the pressure loss, band portion 932 not preferably.But, while making electrode 700 with a part (metallic plate), deposit in the mill and can produce the problem with portion 932.For this reason, in the present invention, adopted the shape of Fig. 8, Fig. 9.

Fig. 9 (a) is the B-B section (central portion) of Fig. 8, and Fig. 9 (b) is the C-C section (connecting portion) of Fig. 8.The direction 701 that has represented wind in Fig. 9 (a).

(to electrode 700)

In addition, in electric discharge device 1000, in order to reduce the pressure loss of flat part 731, consider the inflow direction of wind, make the face with respect to lower box 800 to the flat part 731 of electrode 700, tilt angle theta (Fig. 7).Make flat part 731 with respect to the opening surface inclination certain angle θ of upper box 200 and lower box 800, like this, the inclination to the flat part 731 of electrode 700 being arranged in lower box 800 does not hinder flowing of wind.Angle θ to the flat part 731 of electrode 700, is most preferably parallel to the inflow angle θ (w) (θ (w)=θ) of wind.If the angle θ to the flat part 731 of electrode 700, is that 0 ° (parallel) is above below 30 ° with respect to the inflow angle θ (w) of wind, can ignore the impact of the pressure loss.Otherwise, if the angle θ of flat part 731 is also larger than 30 ° with respect to the inflow angle θ (w) of wind, make significantly the power consumption of air conditioner 3000 increase.Specifically, if the power consumption that can cause the obstruction of wind when carrying product increases, when maximum quantity of wind, be suppressed at below 1W, can think that impact is little.

(shape of sparking electrode 300)

Sparking electrode 300, when electric wire cross section is circle, diameter of section is left and right.When sparking electrode 300 has been applied in high voltage, if local electric field strength has surpassed 10kV/cm, generate radial electric discharge and the electric field of 360 degree directions.The diameter of electric wire 303 is less, and electric-field intensity is higher, more easily discharges, generates electric field.But, sectional area hour, hot strength dies down, easily broken string.

(when electric wire 303 is square-section)

In contrast, during the sparking electrode 300 of the rectangular shape that employing You Chang limit, electric wire cross section and minor face form, long limit is 0.1～1.0mm, and minor face is 0.01～0.2mm.When cross section is the electric wire 303 of rectangle, because minor face is shorter than long limit, so electric field concentrates on minor face, electric discharge is many to produce near minor face.Because minor face is 2 positions, so, from 2 position electric discharges.

(ratio of the long limit/minor face of electric wire 303)

Long limit is 1～10 left and right with the ratio (long limit/minor face) of minor face.By this, than increasing, minor face keeps small size (keeping easily electric discharge), can amass by enlarging section, so, there is the effect that improves hot strength and be not easy broken string when keeping electric discharge.In addition, by this, than increasing, minor face keeps small size (keeping easily electric discharge), can amass by increasing section, so, can obtain the effect that part increases, electric field more strengthens that produces electric field, and the effect increasing to the average field intensity to electrode 700 from sparking electrode 300.Viroplankton during therefore, by electric field space, the inactivating efficacy of the bacterium that swims increase.

The electric wire 303 of sparking electrode 300 is with respect to as follows to the configuration of electrode 700.As shown in Figure 12 (b), configuration of wires 303, makes the long limit of rectangle vertical with lower box 800 (Figure 12 (b) Z direction), 800 one-tenth levels of minor face and lower box (directions X of Figure 12 (b)).That is, flat part 731 is with respect to lower box 800 tilt angle theta, and sparking electrode 300 is not arranged to substantially vertical (parallel) obliquely with respect to lower box 800.

Flat part is with respect to imaginary datum level 752(Fig. 7) the predetermined angle θ that tilts, this imagination datum level 752 and the imaginary plane quadrature using orientation 742 as normal direction.As shown in Figure 12 (b), the electric wire 303 of sparking electrode is configured to minor face and imaginary datum level 752 almost parallels of its rectangle.Utilize the configuration of such electric wire 303, electric wire 303 is not allowed easily broken, and electric-field intensity is high.

(size of electric wire 303)

When the sectional area of electric wire 303 is large, hand easily pinches the electric wire of sparking electrode 300, easy when stretch-draw, bending assembling.Specifically, grow that limit/minor face is more than 3, long limit is that 0.2mm is above, minor face is that 0.03mm is above, sectional area is 0.01mm ²when above, can obtain and be not easy broken string, easy, the easy effect that produces electric discharge at minor face 2b of assembling.Long limit/minor face is more than 6, long limit is that 0.3mm is above, minor face is that 0.04mm is above, sectional area is 0.015mm ²when above, compare with the sparking electrode of circular cross-section before, can obtain be not easy significantly broken string, assembling easily, at minor face 2b, easily produce the effect of electric discharge.Now, if minor face not below 0.1mm, electric field does not concentrate on minor face, so minor face is preferably below the above 0.1mm of 0.04mm.If long limit is not below 0.6mm, electric field does not concentrate on minor face, in order to obtain identical discharge current, needs large voltage more than 7kV, so long limit is preferably below the above 0.6mm of 0.3mm.Under such condition, available 6kV discharges below, can form high voltage source in low price ground.The radius of the sparking electrode of general circular cross-section is 0.1mm before, and sectional area is 0.0076mm ²so,, above-mentioned tabular sparking electrode has the sectional area of approximately 2 times.Therefore, hot strength increases, and is not easy broken string.

In addition, compare with circular cross-section, when the sectional area of square-section is large, in same electrical, depress, the quantity of electric charge increases, and the average field intensity in space increases 2～4 one-tenths, and inactivating efficacy viral, bacterium is increased.

In addition, the electrode of circular cross-section electric wire before, because of electric discharge, dust, moisture, environmental factor aging, thereby from whole, start corrosion around.But doing growth limit/minor face is more than 3 shapes, the effect of stress, from starting corrosion near the concentrated minor face that discharges.Even from short brink corrosion, owing to not corroding from long side, so, compare with circular cross-section, be not easy broken string.Therefore, resistance to environment capacity is high, can use steadily in the long term.

(fillet of electric wire 303)

The bight of sparking electrode 300 is the crossing fillet of minor face and long limit, bight R1 namely, and its radius is 0.001mm～0.1mm.

That is, 0.001mm≤R1≤0.1mm.In addition, R1 hour, electric field concentrates on minor face, so R1 is preferably in 0.01mm.

That is, 0.001mm≤R1≤0.01mm preferably.

(the top rib 201 of upper box 200, the bottom rib 844 of lower box 800)

The details drawing to electrode 700 when Fig. 7 represents the flat part 731 of electrode 700 with respect to the face tilt angle θ of lower box 800.Below, method and the fixing means of the reduction pressure loss are at this moment described.Figure 23 means the figure with the relation of top rib 201 and bottom rib 844 to the flat part 731 of electrode 700.In upper box 200, there is top rib 201(Figure 25), this top rib 201 is arranged on integratedly in upper box 200 and props up and honour electrode 700.Top rib 201, the below from upper box 200 towards short transverse, vertically stretches out from upper box 200.Lower box 800 is formed with bottom rib 844(Figure 16, Figure 17).This bottom rib 844 is arranged on integratedly in lower box 800 and props up and honour electrode 700.Bottom rib 844, the top from lower box 800 towards short transverse, vertically stretches out from lower box 800.

In addition, be positioned at the lower box 800 to connecting portion 733 bottoms of electrode 700, form roughly the same, corresponding with the bending shape shape of bending shape (downside maintaining part 801, Fig. 4) with connecting portion 733.Specifically, lower box 800 has formed and connecting portion 733(the 1st connecting portion 733R, the 2nd connecting portion 733L) downside maintaining part 801(Fig. 4 of shape corresponding to shape), by downside maintaining part 801 from lower side bearing connecting portion 733(the 1st connecting portion 733R, the 2nd connecting portion 733L to electrode 700).

(pressing method of flat part 731)

As previously mentioned, the flat part 731 to electrode 700, with respect to the face of lower box 800, is configured to predetermined angle theta (Fig. 7).As shown in figure 23, flat part 731 is sandwiched fixing by bottom rib 844 these two ribs of the top rib 201 of upper box 200 and lower box 800.In addition, Figure 23 means figure on the arrow Y of Figure 17, flat part 731 and the relation of top rib 201 and bottom rib 844.Top rib 201(Figure 25) are analogous shapes with bottom rib 844.Therefore, even when flat part 731 is because the contact in shaping error, when assembling etc. is former thereby while making flat part 731 have deviation with respect to the angle θ of lower box 800, also flat part 731 can be corrected and be become " predetermined angle θ ".In addition, though have all the year round use, effect that angle can be not sagging yet.The flat part 731 of electrode 700, band portion 732 and connecting portion 733 are arranged in lower box 800.At this moment, make the connecting portion 733(Fig. 8 at two ends, left and right) fully contact with lower box 800, by right middle boxes 500, left middle boxes 600, from top, press.In addition, due to bottom rib 844(Figure 16, Figure 17) be arranged on the grid of lower box 800 (Figure 17), so, build-up of pressure loss.

(shape to electrode 700)

As shown in Figure 8, to electrode 700, be, with flat part 731 with high or be positioned at the connecting portion 733 places bending of flat part 731 bottoms in short transverse, cut flat part 731; The direction bending of the flat part 731 of longitudinal direction topmost to the top from longitudinal direction towards bottom; The direction bending of the flat part 731 of longitudinal direction foot to the bottom from longitudinal direction towards top.Like this, in the both end sides of longitudinal direction, do not form band portion 732, reduce the pressure loss.Therefore, good aerodynamic quality, the power consumption of indoor Air Blast fan reduces.

(to electrode 700: even number)

When the sheet number of flat part 731 is even number, the flat board of the dull and stereotyped and bending of the direction to the bottom from longitudinal direction towards top of direction to the top from longitudinal direction towards bottom bending, forms a pair ofly, and multipair be connected on connecting portion 733 formed.While forming in this wise, in the both end sides of longitudinal direction, band portion 732 not, the pressure loss reduces.Therefore, good aerodynamic quality, the power consumption of indoor Air Blast fan reduces.

(to electrode 700: odd number).

On the other hand, when the sheet number of flat part 731 is odd number, the flat board of the dull and stereotyped and bending of the direction to the bottom from longitudinal direction towards top of the direction bending to the top from longitudinal direction towards bottom, form a pair of, by multipair, be connected on connecting portion 733 and form, the not direction bending of a slice flat part 731 a pair of with 731 one-tenth of the flat boards of longitudinal direction topmost to the top from longitudinal direction towards bottom, or, the not direction bending of a slice flat part 731 a pair of with 731 one-tenth of the flat boards of longitudinal direction foot to the bottom from longitudinal direction towards top.Like this, the both end sides at longitudinal direction does not form band portion 732, pressure loss minimizing.Therefore, good aerodynamic quality, the power consumption of indoor Air Blast fan reduces.

(to electrode 700)

If not with flat part 731 with high or cut bendingly flat part 731 at connecting portion 733 places that short transverse is positioned at flat part 731 bottoms, but while bending, will produce band portion 732 in the way of flat part 731.In addition, the flat part 731 of longitudinal direction topmost is the direction to the top from longitudinal direction towards bottom when bending, the flat part 731 of longitudinal direction foot is the direction to the bottom from longitudinal direction towards top when bending, can produce band portion 732 similarly, so, the pressure loss increases, and the length dimension of longitudinal direction also increased the size being equivalent to portion 732, and spatiality is poor.In addition, while being divided into a plurality of part if do not connect flat part 731, production cost increases.

(to electrode 700)

In addition, to electrode 700, be to arrange and remain in lower box 800, by use, be positioned at below the frame on electrode 700 tops (middle boxes or upper box 200) and pressed electrode 700 from the top of short transverse, can make can not be fixing actively at above-below direction to electrode 700.At this moment, middle boxes or upper box 200 are pressed near the left and right directions two ends of electrode 700, thereby middle boxes or upper box 200 itself do not hinder passing through of wind.

As shown in Figure 4, by right middle boxes 500, the left middle boxes 600 shown in Figure 13, by the 1st connecting portion 733R of the connecting portion 733(to electrode 700, the 2nd connecting portion 733L) cover so that it does not expose and insulate.Connecting portion 733 is arranged in lower box 800.

On being positioned at the right middle boxes 500 on connecting portion 733 tops of electrode 700, left middle boxes 600, also with lower box 800 similarly, formed and had and connecting portion 733(the 1st connecting portion 733R, the 2nd connecting portion 733L) upside maintaining part 501,601(Fig. 4 of shape corresponding to shape), as shown in Figure 4, by upside maintaining part 501,601, from upside, keep connecting portion 733(the 1st connecting portion 733R, the 2nd connecting portion 733L to electrode 700).Like this, with right middle boxes 500, left middle boxes 600 and bottom 800 from sandwiching up and down and be fixedly connected with the bending shape of portion 733.

(1) by like this that connecting portion 733 is fixing, can prevent the angular deviation of flat part 731, use all the year round sagging, can forcibly the angle of flat part 731 be fixed.Therefore, by sparking electrode 300 with to the distance of the flat part 731 of electrode 700, keep certain, can stably discharge, form electric field.

(2) in addition, by middle boxes, cover the connecting portion 733 of electrode 700 and will between sparking electrode 300 and connecting portion 733, insulate, so, even if the distance between the connecting portion 733 under sparking electrode 300 and the state that covered by middle boxes shortens, can not produce unnecessary electric discharge yet.Like this, by covering connecting portion 733 by middle boxes, can shorten sparking electrode 300 and to the distance between electrode 700, so, integral thickness that can attenuate electric discharge device 1000.

In addition, because the unnecessary electric discharge of sparking electrode 300 and connecting portion 733 is suppressed, so, can form stable electric discharge field, electric field.In addition, owing to being arranged on overlappingly the end of device using connecting portion 733 with as the middle boxes of the maintaining part of sparking electrode 300, so, can strengthen the aperture area of width.

In addition, in lower box 800, at HV Terminal maintaining part 841(Figure 17) upper, configuration is to the high-pressure side power supply terminal 709(high voltage supply portion of sparking electrode 300 power supplies).As shown in Figure 4, right middle boxes 500 covers at least a portion of high-pressure side power supply terminal 709.In addition, also HV Terminal maintaining part 841 can be arranged on to the side that left middle boxes 600 covers, by left middle boxes 600, cover high-pressure side power supply terminal 709.

As shown in Figure 13, Figure 18, the side by device center side (left middle boxes 600 sides) in right middle boxes 500, has formed the insulation wall 505 vertically erecting from the bottom surface of right middle boxes 500.

(breach 506,606)

Be that right middle boxes 500 has the insulation wall 505 consisting of insulating materials.The end of a plurality of flat parts 731 that this insulation wall 505 is arranged along almost parallel erects upward, and has formed the breach 506 passing for sparking electrode 300.Left middle boxes 600 has insulation wall 605, breach 606(Figure 14 similarly).Like this, by middle boxes, insulation wall being set, can expand space length and the creep age distance of sparking electrode 300 and connecting portion 733.Therefore, can prevent unnecessary electric discharge, slimming that can implement device.Right middle boxes 500, left middle boxes 600 breach 506, breach 606 that have respectively, that for sparking electrode 300, pass, for the ease of sparking electrode 300, pass, form U font or V font, as shown in figure 13, its upper opening (opening 506-1, opening 606-1), bottom closure.Figure 13 represents the situation of V font breach.During U font, the horizontal stroke of breach 506, breach 606 is wide is roughly the same width from top to bottom.During V font, the horizontal stroke of breach is wide be from top (upper box direction) towards bottom (lower box direction) constriction gradually.Like this, when assembling, sparking electrode 300 can not be stuck on insulation wall in the position higher than predetermined altitude.In addition, opening also serves as a mark, and easily, available insulation wall 505,605 prevents and paradoxical discharge to electrode 700 conscientiously in assembling.

In addition, as shown in figure 13, side frame on right middle boxes 500(the 1st) side frame and on left middle boxes 600(the 2nd), away from the direction of insulation wall 505,605 and the length direction end of flat part 731, be respectively smooth par 508,608.That is, the left end of the right-hand end of right middle boxes 500, left middle boxes 600 is smooth par 508,608(Figure 13).Like this, by the left end of the right-hand end of right middle boxes 500, left middle boxes 600 is made for to flat condition, to carry out sparking electrode 300(be mainly electric wire 303) during through the assembling operation of middle boxes, can not be subject to the obstruction of wall, rib, the assembling operation that terminal is embedded to power supply etc. is easy.As shown in figure 13, the height of the par 508,608 of the left end of the right-hand end of right middle boxes 500, left middle boxes 600, the height low (Figure 14, Figure 18) of the electric wire 303 of the sparking electrode than stretch-draw under the state of device.Like this, pinching and during the operation of stretch-draw sparking electrode 300, middle boxes might as well be in the way with finger, assembling operation is easy.In addition, the right-hand end of lower box 800 and the height of left end are also low at the height of the electric wire 303 of the state of device than stretch-draw.Like this, pinching and during the operation of stretch-draw sparking electrode 300, lower box 800 might as well be in the way with finger, assembling operation is easy.Right-hand end and left end in lower box 800 are provided with pawl 851～854(Figure 16, Figure 17), middle boxes embeds and is fixed on these pawls 851～854, so the end height of middle boxes is lower than the end height of lower box 800.Due in lower box 800, can not form the horizontal side of device, so, side surface part 207,208 by the upper box 200 shown in upper box 200(Figure 25 (aftermentioned)) form the horizontal side of device, by after sparking electrode 300 stretch-draw, finally, upper box 200 is embedded to lower box 800 from top, be fixed.

(extension 507)
