Device fuse is placed in the middle in capacitor case, and capacitor body is not crooked, it is ensured that epoxy resin can be comprehensive by capacitor body
Wrap up, to meet the insulation distance requirement between capacitor body and shell, it is ensured that the low loss-value of capacitor.In reality
In production, capacitor cable is welded on the both ends metal spraying face of capacitor body, when loading capacitor plastic housing shell, due to
Cable line length and have dead weight capacitor body it is easily crooked.In batch production, large number of capacitor waste product is easily caused.And
And due to the correction that can not do over again after epoxy resin cure, it is very big to being lost caused by manufacturing enterprise.
Utility model content
The utility model is in view of the deficiencies of the prior art, there is provided and one kind is simple in structure, reliability is high,
Suitable for producing in enormous quantities and using, quick wiring capacitance device fuse placed in the middle time saving and energy saving, that qualification rate is high is operated
Capacitor case.
In order to solve the above technical problems, a kind of capacitor case of quick wiring capacitance device fuse placed in the middle of the utility model,
The cover board being adapted including shell and therewith, wherein, the inner side of shell is equal
Several plano-convex platforms are arranged at bottom in some positioning bars of cloth, shell；Cover plate central position is equipped with through-core hole and three
Positioning column.
As the preferred of the utility model, shell is cylindrical plastic shell.
As further improvement of the utility model, positioning bar includes vertical section and pushes away to pull out section, and vertical section pulls out section with pushing away
Angle ɑ is 3~5 °, and the height ratio that vertical section pulls out section with pushing away is 7:1；The height of positioning bar：Height=0.7~0.75 of shell：1,
The width of positioning bar is 1~1.3mm, the outside diameter of shell：Outside diameter=17.5~18 of plano-convex platform:1st, the height of shell：Plano-convex platform
Height=10:1.
Using above-mentioned technical proposal, the structure size design of positioning bar is pacified easy to capacitor body toward sinking inside plastic housing
Dress, the special construction size design of the plano-convex platform of plastic housing bottom so that the space that plano-convex platform branch overhangs can avoid capacitor body
On solder joint is raised and lead height so that capacitor body can be upright；Again liquid-state epoxy resin can be allowed easily to fill wherein.
As the preferred of the utility model, the number of positioning bar is the six roots of sensation；The number of plano-convex platform is four.
The beneficial effects of the utility model in summary：There is the through-core hole supporting with cable line footpath on the cover board, ensure
The capacitor body of cable or other exits can quickly install center ofthe, while three positioning above cover board with plastic housing
By capacitor body, positioning up and down, three pillars have the stability of triangle to pillar inside plastic housing, stop capacitor core group
Up floated from buoyancy effect during encirclement comprehensive by liquid-state epoxy resin, after epoxy resin cure, in capacitor body
The epoxy resin isolation strip of the insulation of a safety is formed between shell, capacitor core group is completely by epoxy resin sealing column.
As long as cover board and shell are coordinated installation by operator, liquid-state epoxy resin will not be touched, plays and positions convenient, easy to operate, province
It is Shi Shengli, reliable
Property it is high, suitable for produce in enormous quantities and use, qualification rate it is high, without process contamination.
Brief description of the drawings
Fig. 1 is the structure diagram of the quick capacitor case of wiring capacitance device fuse placed in the middle of the utility model；
Fig. 2 is the top view of the quick capacitor case of wiring capacitance device fuse placed in the middle of the utility model；
Fig. 3 is the structure diagram of the utility model positioning bar.
Wherein, 1 capacitor case, 2 cover boards, 3 through-core holes, 4 positioning columns, 5 positioning bars, 6 plano-convex platforms.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
Embodiment one：
The capacitor case of a kind of quick wiring capacitance device fuse placed in the middle described in the utility model, such as Figure of description 1
Shown in 2, by taking diameter 35, a height of 55mm plastic housings as an example：A length of 40mm of positioning bar, width 1mm, the height of vertical section are
35mm, it is 5mm to push away and pull out the height of section, and the angle ɑ that vertical section and pushing away pulls out section is 3 °, easy to capacitor body toward sinking inside plastic housing
Installation.The a diameter of 2mm of plano-convex platform of plastic housing bottom and bottom circle center distance are 5.5mm, the space energy which overhangs
