Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Fig. 2 ~ 4, the capacitor sealed in unit, including shell 2, cover board 3, turntable 4, shaft coupling 5, motor 6,
The cover board 3 and shell 2 are hinged, and the turntable 4 is arranged on the inside of shell 2, and the shaft coupling 5 and motor 6 are arranged on turntable 4
Lower section, the motor 6 by shaft coupling 5 drive turntable 4 rotate；The top of the turntable 4 is provided with multiple blind round hole 42,
Blind hole 42 is symmetrical on the top of turntable 4 centered on the center of circle of turntable 4；It is provided in the blind hole 42 and matches with blind hole 42
The fixing sleeve 7 of conjunction, fixing sleeve 7 include barrel-shaped main body 71, the top end opening of main body 71 and the bottom end closure of main body 71, main body 71
Madial wall be provided with bulge loop 72 and inner cushion layer 73, be provided with gap between bulge loop 72 and the bottom of main body 71, bulge loop 72 and main
Body 71 is fixedly connected, and inner cushion layer 73 is arranged between the openend of bulge loop 72 and main body 71, and inner cushion layer 73 and main body 71 are fixed and connected
It connects.
As shown in Figure 1, capacitor includes capacitor case 11, cover board 12, epoxy resin 13, electrode 14, in capacitor plus
During work, the epoxy resin 13 of liquid is poured into capacitor case 11, cover board 12 and capacitor case 11 are fixed and completed
Afterwards, if capacitor case 11 is aluminum hull, cover board 12 is fixed on to the top of capacitor case 11 using stamping technology；It immediately will be upper
It states capacitor to fill in fixing sleeve 7 so that cover board 12 contacts bulge loop 72, and capacitor is in the state of " handstand ", in bulge loop 72
Under blocking, due to being provided with gap between the bottom of bulge loop 72 and main body 71, electrode 14 is avoided to hit the bottom of main body 71；Due to
The presence of inner cushion layer 73, the inner cushion layer 73 is by the very excellent Heveatex of elastic property, natural rubber or butyl rubber
One kind be made, 73 one side protective condenser shell 11 of inner cushion layer avoids capacitor case 11 from being scratched, worn, the opposing party
Face, inner cushion layer 73 have high resiliency so that main body 71 and capacitor case 11 are tightly combined；After capacitor is filled in fixing sleeve 7,
The tail end of capacitor is exposed at the outside of fixing sleeve 7, convenient for subsequently taking out；Then fixing sleeve 7 is filled in blind hole 42, retainer body
71 openend upward, is then shut off cover board 3, opens motor 6, and motor 6 drives turntable 4 to rotate by shaft coupling 5, turntable 4
Rotating speed be 800 ~ 1000r/min, due to blind hole 42 be located at turntable 4 center, 4 high speed rotation of turntable generate centrifugal force, from
Under the action of mental and physical efforts, gap that the epoxy resin 13 of liquid is extruded and is filled between capacitor case 11 and cover board 12 and
In gap between electrode 14 and cover board 12, although gap is small and 13 viscosity of epoxy resin of liquid is big, in turntable 4
Under the action of upper centrifugal force, the time that the epoxy resin 13 of liquid is filled into gap is drastically shortened, simultaneously because gap volume
Very small, 13 viscosity of epoxy resin of liquid is big, though there are centrifugal force, the epoxy resin 13 of liquid also be difficult to from gap to
The external of capacitor is flowed out, meanwhile, after the epoxy resin 13 of liquid is filled into gap, the liquid-state epoxy resin 13 in gap is difficult
It flows back again；After turntable 4 rotates 5 ~ 10min, fixing sleeve 7 from blind hole 42 is taken out, then again takes capacitor from fixing sleeve 7
Go out, after placing a period of time, the epoxy resin 13 of liquid is formed by curing solid epoxy resin 13, capacitor case 11 and cover board
The gap between gap and electrode 14 and cover board 12 between 12 is filled by solid epoxy resin 13, is not only able to avoid sky
Moisture in gas enters the inside of capacitor, and since solid epoxy resin 13 is in the inside of capacitor, avoids solid-state
Epoxy resin 13 occur weathering, solid 13 rate of ageing of epoxy resin is very slow, and the service life of the capacitor is significantly prolonged
It is long.
For convenience of fixing sleeve 7 is taken out, flanging 74, flanging 74 and main body are provided on the outside of 71 openend of main body
71 are an integral structure.Flanging 74, which not only facilitates, takes out fixing sleeve 7, and flanging 74 has positioning action.
Fixing sleeve 7 is filled in and removes for convenience, matching between the blind hole 42 and main body 71 is combined into clearance fit.To ensure
It is tightly combined between fixing sleeve 7 and turntable 4, the outside of 71 openend of main body is provided with the outer bed course 75 of a circle, outer bed course 75
The lower section of flanging 74 is arranged on, outer bed course 75 is fixedly connected with main body 71.The outer bed course 75 is by the excellent day of elastic property
One kind in right latex, natural rubber or butyl rubber is made.Under the action of outer bed course 75, tied between fixing sleeve 7 and turntable 4
It closes closely, simultaneously because outer bed course 75 has elasticity, is also convenient for taking out fixing sleeve 7.
For ease of taking out fixing sleeve 7, the depth of the blind hole 42 is less than the height of main body 71.
For the bond strength being further ensured that between fixing sleeve 7 and turntable 4, fixing sleeve 7 is avoided to be got rid of under high speed rotation
Go out；The center of the turntable 4 is provided with cylinder-shaped magnet 41, and magnet 41 is fixedly connected with turntable 4；The turntable 4,71 and of main body
Flanging 74 is made by metallic iron.Under the action of magnet 41, turntable 4 has magnetism, and turntable 4 can be by 71 He of main body
Flanging 74 firmly adsorbs, and the bond strength between fixing sleeve 7 and turntable 4 further improves；Meanwhile 41 optional electricity consumption of magnet
Magnet reduces the follow-up resistance for taking out fixing sleeve 7.Under double action using magnetic-adsorption and outer bed course 75, avoid revolving at a high speed
The fixing sleeve 7 turned is thrown away from turntable 4, and device security further improves.Wherein, fixing sleeve 7 not only can protective condenser, keep away
Exempt from capacitor to damage in high speed rotation, and fixing sleeve 7 also ensures bond strength between capacitor and turntable 4, keeps away
Exempt from high-speed rotating fixing sleeve 7 to throw away from turntable 4.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
