Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in Fig. 1 ~ 4, the magnet charger capacitor, including barrel-shaped shell 1, the capacitor core inside shell 1
Group, cover plate 3, the lower end closed of the shell 1 and the open upper end of shell 1, the cover plate 3 are fixedly connected with the upper end of shell 1；
The capacitor core group includes six cylindric capacitor cores 21, and seven apertures in the human head positioning sleeve 5 is provided with the middle part of the capacitor core group；
The seven apertures in the human head positioning sleeve 5 includes six roots of sensation pipe body 51, and six roots of sensation pipe body 51 forms a circle and the lateral wall phase of adjacent pipe body 51
Mutually circumscribed, six roots of sensation pipe body 51 is surrounded by centrally located medium pore 52, and the pipe body 51 is set in the outer of capacitor core 21
Portion；The shell 1 is internally provided with barrel-shaped inner casing 6, the upper end closed of the inner casing 6 and the open at its lower end of inner casing 6, described
The height of inner casing 6 is less than the height of shell 1, and the lower end of the inner casing 6 in the middle part of the shell bottom of shell 1 with being fixedly connected, the shell 1
Shell bottom center be provided with first through hole 11, first through hole 11 connects with the inner chamber of inner casing 6；The inner casing 6 passes through medium pore 52
And the lateral wall of inner casing 6 is cut in outside the hole wall of medium pore 52, the madial wall of the lateral wall and shell 1 of the pipe body 51 is tangent；
Interval is provided between the lower end of the capacitor core 21 and the shell bottom of shell 1, the inside of the shell 1 is also filled with insulation and led
Thermal medium 4.
Shell 1 and inner casing 6 use aluminum hull, and the insulated heat-conducting medium 4 is that the epoxy resin containing heat filling is gluing
Transformer oil can be selected in agent or the conduction oil with insulation effect, the conduction oil with insulation effect.Can be by shell by inner casing 6
The heat in 1 centre position outwardly distributes in time, avoids heat from being collected among shell 1, is favorably improved the magnet charger electric capacity
The radiating effect of device.
The seven apertures in the human head positioning sleeve 5 is formed a circle by six roots of sensation pipe body 51 and the mutually circumscribed structure of the lateral wall of adjacent pipe body 51
Into the structure of plum blossom-shaped, therefore, it is seven holes that the hole in six centers of pipe body 51, which is added medium pore 52 and had altogether,.Just the six roots of sensation is justified
Body 51, which forms a circle, can surround medium pore 52, and this causes utilization of the seven apertures in the human head positioning sleeve 5 to the inner space of shell 1 to reach
It is optimal, when ensureing that capacitor core group is stably being fixed by seven apertures in the human head positioning sleeve 5, also avoid wasting the space inside shell 1.Seven
The preparation method of hole positioning sleeve 5 is simple, six roots of sensation pipe body 51 can form a circle and lead between the lateral wall of adjacent pipe body 51
Glue is crossed to be fixedly connected；Extruding machine can also be used by 5 extrusion moulding of the seven apertures in the human head positioning sleeve.Each capacitor core 21 is just
Inject in the corresponding inner chamber of pipe body 51, the pipe body 51 entangles the middle part of capacitor core 21, pipe body 51 and electricity
It can be fixedly connected between container core 21 using glue, can also be by the way of interference fit between pipe body 51 and capacitor core 21
It is fixed.In seven apertures in the human head positioning sleeve 5, the lateral wall of six roots of sensation pipe body 51 can be tangent with the lateral wall of inner casing 6, and six pipes
The lateral wall of body 51 can also be tangent with the madial wall of shell 1, therefore, in the presence of seven apertures in the human head positioning sleeve 5, capacitor core group quilt
Seven apertures in the human head positioning sleeve 5 is fixed on the inside of shell 1, also causes between capacitor core 21 and the lateral wall of inner casing 6, adjacent capacitor
Larger gap be present between core 21 and between the madial wall of capacitor core 21 and shell 1, this is advantageous to insulated heat-conducting medium 4
Six capacitor cores 21 are fully wrapped around, not only avoid capacitor core 21 from leaking electricity, and also help capacitor core 21 and exist
Radiated during operation.Wherein, be made because pipe body 51 is generally rubber or plastics, but the lateral wall of pipe body 51 with it is outer
Contact area between the madial wall of shell 1 is small, and the contact area between the lateral wall of pipe body 51 and the lateral wall of inner casing 6 is small,
Therefore radiating interference of the seven apertures in the human head positioning sleeve 5 to capacitor core group is very small.
Wherein, inner casing 6 also has the function that to support seven apertures in the human head positioning sleeve 5, including ensureing that six capacitor cores 21 are symmetrical
The surrounding of shell 6, six capacitor cores 21 are evenly distributed inside shell 1 so that interfered between six capacitor cores 21 less,
This is advantageous to the magnet charger capacitor and stably run；Seven apertures in the human head positioning sleeve 5 is fixed on inner casing 6, and this to be positioned by seven apertures in the human head
Six capacitor cores 21 that set 5 is fixed easily are in vacant state in the inside of shell 1, and this is advantageous to the insulated heat-conducting medium 4 of perfusion
Six capacitor cores 21 are fully wrapped around, avoid six capacitor cores 21 from leaking electricity.
When insulated heat-conducting medium 4 is the conduction oil with insulation effect, can be adopted between capacitor core 21 and pipe body 51
Reinforced with glue, can also use glue to reinforce between seven apertures in the human head positioning sleeve 5 and inner casing 6.When insulated heat-conducting medium 4 is to be filled out containing heat conduction
During the epoxyn of material, because the epoxyn containing heat filling after solidification is solid, as long as therefore
Ensure the lower end of the capacitor core 21 and the shell bottom of shell 1 before the epoxyn that perfusion liquid contains heat filling
Between enough intervals be present；This in the lateral wall of inner casing 6 by being also arranged with circular ring washer 61, the inner ring of ring washer 61
It is fixedly connected with the lateral wall of inner casing 6, the ring washer 61 is arranged on the lower section of pipe body 51.Circular ring washer 61 have it is spacing,
The effect of retaining, seven apertures in the human head positioning sleeve 5 are blocked by circular ring washer 61, can effectively ensure that lower end and the shell 1 of capacitor core 21
Shell bottom between have enough intervals, and circular ring washer 61 can also stop that capacitor core 21 contains heat filling in liquid
Epoxyn in fall naturally.
Further, to increase the area of first through hole 11 to greatest extent, radiating effect is improved, the first through hole 11 is
Circular hole, the diameter of first through hole 11 are equal to the internal diameter of inner casing 6.
Further, as shown in figure 5, the center of the capacitor core 21 is provided with cylindric plug 211, plug 211
Center is provided with the second through hole of regular hexagon 212, and the central shaft of the second through hole 212 is conllinear with the central shaft of plug 211.Capacitor
Core 21 is made of by the way that metallized film is carried out into metal spraying again on plug 211.In wound capacitor core 21, by positive six
The contact pin of prism-shaped is injected in the second through hole 212, and contact pin, which rotates, drives plug 211 to be wound operation, and regular hexagon second is logical
The contact pin of hole 212 and positive six prismsby shape, which coordinates, avoids the plug 211 in rotating from skidding.The central shaft of second through hole 212 with
The central shaft of plug 211 is conllinear, ensures metallized film uniform force in winding process.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
