Embodiment
As shown in Figure 1, Figure 3, the utility model provide a kind of can the environment protection type capacitor shell of injecting glue fast, comprise housing 10, described housing 10 has the lower arcuate surface 12 protruded downwards.This technical scheme is by being designed to lower convex arcuate structure by the bottom surface 12 of capacitor case, namely can guarantee that the electrode to being positioned at above bottom surface 12 fully infiltrates, the volume of bottom can be reduced again, thus reduce the injection rate of electrolyte, effectively save production cost.
Further, be symmetrically arranged with multiple stupefied bar 13 of reinforcement being connected to housing 10 below bottom surface 12, the effect strengthening stupefied bar 13 has two aspects: one is improve the bonding strength between bottom surface 12 and housing 10; Two is increase bottom surface 12 and the contact area of capacitor working face, improves stability when capacitor is placed.
Further, as shown in Figure 2, housing 10 inwall is vertically evenly provided with multiple bar blocks 11, and described capacitor case also comprises cover plate 20, and described cover plate 20 covers in bar blocks 11, and wherein the effect of bar blocks 11 supports cover plate 20.
Further, as shown in Figure 4, cover plate 20 Central Symmetry is provided with two wiring holes 21, described cover plate 20 is also provided with multiple through hole 24 running through plate face, why two wiring holes 21 are symmetricly set on cover plate 20 center in this structure, to ensure no matter how cover plate 20 is placed in housing 10, and wiring hole 21 is all in the center of housing 10, improves production efficiency.Wherein the effect of through hole 24 is the injection rates improving electrolyte and epoxy resin.Find in actual use; because the viscosity of electrolyte and epoxy resin is larger; not easily be filled into the edge of housing 10; usually can form bubble at edge; therefore cover plate 20 edge can be arranged to the structure of chamfering 23; facilitate the discharge to bubble in electrolyte and epoxy resin injection process, ensure that the uniformity of each region electrolyte and epoxy resin in housing 10, guarantee that capacitor long-term stability uses.
Further, cover plate 20 is also provided with two block button holes 22, described block button hole 22 is mutually corresponding with wiring hole 21, described capacitor case also comprises binding post 40, described binding post 40 is fastened on corresponding wiring hole 21 with block button hole 22, and this structure coordinates the fixing of the line terminals 40 that achieves a butt joint by wiring hole 21 with block button hole 22.Simultaneously, as shown in Figure 5, a kind of binding post 40 can be designed for said structure, this binding post 40 comprises wire terminals 41, electrode connecting end 42 and afterbody fastening end 43 successively according to structural order, and described wire terminals 41 plugs together with wiring hole 21, and described afterbody fastening end 43 plugs together with block button hole 22, and electrode connecting end 42 is exactly the region with electrode welding, this binding post 40 plugs together in wiring hole 21 and block button hole 22, convenient disassembly, good fixing effect.
In the above-described embodiments, as shown in Figure 2, conveniently capacitor is fixed to preposition, triangular plate 30 can be fixedly installed on capacitor case, this fixed head 30 is arranged on position concordant with bottom surface 12 outside housing 10, described fixed head 30 is provided with the connecting hole 31 running through plate face, during use, easily capacitor can be fixed to corresponding position by screw through connecting hole 31, and the fixed head 30 of triangular structure, also can ensure the fastness of fixed structure to a certain extent.
Further, connecting hole 31 side has opening 32, and this opening 32 structure can meet the screw of more polytypic, avoids damaging because nail bar more slightly causes connecting hole 31 to expand in some screw fixation procedure, affects the normal fixing of capacitor.Meanwhile, in order to improve the fixed effect between fixed head 30 and housing 10, reinforcement 33 can be set between fixed head 30 and housing 10.
