Embodiment
First embodiment: a kind of embodiment that at first combines Fig. 1, the capacitor that provides for the utility model shown in Figure 2; It has shell 1 and the electric capacity body of being located in the shell 1 15; An end of said electric capacity body 15 is provided with two electrodes 2; The improvement of this capacitor is one-body molded on the said shell 1 flange seat 3 arranged, and said flange seat 3 is provided with three fixing holes 4.And flange seat described in the present embodiment 3 is provided with near shell 1 end at electrode 2 places.Said flange seat 3 of the while one side of electrode 2 dorsad is provided with a circle flange 5, and also is provided with a fool proof protruding 6 on flange seat 3 peripheries.And be equipped with screwed hole 2a on two electrodes 2 in the present embodiment.
Combine Fig. 3 and shown in Figure 4 again; The utility model provides a kind of AC converter that adopts above-mentioned capacitor simultaneously, this AC converter have reactor shell 7, fixed interval in reactor shell 7 circuit board 8 and keyset 9 and simultaneously with the fixing capacitor of circuit board 8 and keyset 9.The structure of said capacitor is seen Fig. 1, Fig. 2 and narration before; And its concrete assembly structure in AC converter is following: two electrodes 2 of said electric capacity body 15 ends all are fixed on the circuit board 8 through the electrode screw 11 that cooperates with their screwed hole 2a, with the electric connection of realization with circuit board 8.Said keyset 9 is provided with the installing hole that passes of shell 1 of power supply container; Also be provided with on the keyset 9 simultaneously with flange seat 3 on 3 fixing holes, 4 corresponding 3 screw holes (not marking), these 3 screw holes are through cooperating with mounting flange seat 3 and keyset 9 with three screws 10 that pass respective fixation hole 4.And said flange seat 3 is between circuit board 8 and keyset 9.
The circle flange 5 that is provided with of the one side of electrode 2 is inconsistent with keyset 9 dorsad for said flange seat 3, thereby effectively the shell 1 of capacitor for voltage protection is not come moisture freely, dust, the destruction of environmental stresses such as gas with electric capacity body 15.
Said flange seat 3 peripheries are provided with fool proof protruding 6; And also be provided with it corresponding fool proof protruding (invisible among the figure) on the keyset 9; When the fool proof on the flange seat 3 protruding 6 is relative with the fool proof convexity on the keyset 9; Fixing hole 4 on the said flange seat 3 is aimed at the screw hole on the keyset 9 one by one, thereby is convenient to assembling.
In conjunction with second embodiment of Fig. 5, the capacitor that provides for the utility model shown in Figure 6, its structure is compared with the capacitor that first embodiment provides, difference as follows:
1) one-body molded on the shell 1 have a flange seat 3, and said flange seat 3 is provided with four fixing holes 4;
When 2) placing a plurality of capacitor to the AC converter of this capacitor of utilization, the setting and the assembling of positive and negative electrode have requirement, and present embodiment possesses two kinds of fool proofs designs for this reason:
The first becomes long round body with the shaped design of two electrodes 2 (being respectively positive and negative electrode) of its electric capacity body 15 ends; But arranged direction is different; That kind as shown in Figure 6, an electrode 2 (positive electrode) transverse arrangement of turbo of below wherein, an electrode 2 (negative electrode) of top is vertically arranged; Distinguish positive and negative electrode with this, be convenient to its assembling in AC converter.
Its two be in the present embodiment electric capacity body 15 ends for circular; The angle angle of the hole heart line of four fixing holes 4 is distinguished through design to some extent on its center of circle to the flange seat 3; That kind as shown in Figure 6, four angles are designed to 90 °, 90 °, 95 °, 85 ° successively by clockwise trend, and the fixing hole on the keyset 9 of corresponding AC converter on setting and this flange seat 3 is screw hole one to one; During practical set; If angle is inconsistent, then fixing hole 4 can't be aimed at the screw hole on the keyset 9, also just can't correctly assemble positive and negative electrode.Certainly, only for giving an example, the utility model is not limited thereto above-mentioned angle.
Certainly the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the people who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection range of the utility model with this.All modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection range of the utility model.
