Description
Technical field
The present invention relates to a kind of solenoid, coil insulation framework and prepare the modified nylon materials of the skeleton.
Background technology
Existing solenoid, which is mainly made up of coil case and coil, and coil case one end is provided with concentric setting
Put and for placing the placing trough of coil, and in order to make to be insulated between coil and spacing shell, existing way is past
Toward the outside winding non-woven fabrics that can be selected in coil, its structure is as shown in Figure 9.Its assembling process is：First in the outer bread of coil 8
Non-woven fabrics 10 are wrapped, then the coil 8 for having coated is placed in placing trough 91, subsequently asphalt mixtures modified by epoxy resin is poured into toward in placing trough
Fat, you can realize the fixation between coil 8 and coil case 9.
Above-mentioned electromagnetic coil structure is simple, but its drawback for existing is, during assembling solenoid, needs
The winding non-woven fabrics 10 toward on coil 8 of one circle circle, so as to cause packaging efficiency low.
The content of the invention
The first object of the present invention be to provide it is a kind of quickly can realize assemble coil insulation framework, its can quickly with
Coil realizes assembling, improves packaging efficiency.
The present invention above-mentioned technical purpose technical scheme is that：A kind of coil insulation framework, bag
The base plate of support of annular is included, the base plate of support inner ring surface and outer ring surface extend axially upward to form inner ring surface stop respectively along which
Piece and outer ring surface barrier sheet, the outer ring surface barrier sheet, form for placing coil between base plate of support and inner ring surface barrier sheet
Storage tank.
By above-mentioned setting, this coil insulation framework is first put into coil in storage tank, now during use
Inner ring surface barrier sheet can play good position-limiting action with outer ring surface barrier sheet to coil, while also can play very to coil
Good clamping action.Additionally, after in the placing trough that coil insulation framework is placed on coil case, inner ring surface barrier sheet and
Outer ring surface barrier sheet can be good at coil with coil case to keeping apart, and be prevented effectively from coil case appearance powered existing
As.
Preferably, the inner ring surface barrier sheet and outer ring surface barrier sheet are the arc-like sheet being arranged concentrically with base plate of support.
By above-mentioned setting, after coil is placed in storage tank, the outer ring surface of inner ring surface barrier sheet can be with coil
Inner ring surface fit together well, the inner ring surface of outer ring surface barrier sheet can be good at the outer ring surface of coil and be fitted in one
Rise, effectively increase the contact area between inside and outside anchor ring barrier sheet and coil, and after increasing contact area, inner and outer rings
There is between face and coil larger frictional force, avoid coil to depart from storage tank to a certain extent.
Preferably, the inner ring surface barrier sheet has multiple and is distributed along base plate of support inner ring surface uniform circular.
By above-mentioned setting, multiple inner ring surface barrier sheets can be good at playing position-limiting action to coil, prevent coil edge
Its radial direction is moved；The presence of inner ring surface barrier sheet simultaneously also can play iris action between coil and coil case,
Prevent coil case powered；Additionally, inner ring surface barrier sheet is divided into multi-disc, which is relative to an annular barrier sheet, Neng Gouyou
The material-saving of effect, reduces production cost.
Preferably, the outer ring surface barrier sheet has multiple, and the radian of the outer ring surface barrier sheet is more than inner ring surface barrier sheet
Radian.
By above-mentioned setting, multiple outer ring surface barrier sheets can be good at playing position-limiting action to coil, prevent coil edge
Its radial direction is moved；The presence of inner ring surface barrier sheet simultaneously also can play iris action between coil and coil case,
Prevent coil case powered；Additionally, outer ring surface barrier sheet is divided into multi-disc, which is relative to an annular barrier sheet, Neng Gouyou
The material-saving of effect, reduces production cost；And the diameter of outer ring surface is the diameter for being greater than inner ring surface, therefore also just it is not required to
The radian of outer ring surface barrier sheet is arranged to into identical with the radian of inner ring surface barrier sheet, can further material-saving, reduce
Production cost.
Preferably, the inner ring surface barrier sheet and the interlaced setting of outer ring surface barrier sheet.
By above-mentioned setting, the projection of inner ring surface barrier sheet and outer ring surface barrier sheet on coil, almost can cover
Whole circular arc, therefore no matter coil is moved along which direction of horizontal direction, inside and outside barrier sheet can produce one to coil
Fixed barrier effect, realizes to the good position-limiting action of coil.
Preferably, the base plate of support is provided with through wires hole, through wires hole side wall be provided with by through wires hole be separated into into
The dividing plate of line through wires hole and outlet through wires hole, the base plate of support outer ring surface just to form banking stop to upwardly extending at dividing plate, institute
The width for stating banking stop is more than the width of dividing plate but is less than the width of through wires hole, and the outer ring surface barrier sheet, banking stop are uniform
Circle distribution is on the lateral wall of base plate of support.
By above-mentioned setting, inlet wire through wires hole and there is through wires hole and separated by dividing plate, can effectively by inlet wire
Through wires hole and the wire occurred between through wires hole separate, and prevent the phenomenon of short circuit；And when by banking stop along itself and fixation
The connecting line of base plate connection is turned over when turning 90 degrees, and a banking stop part is covered on inlet wire through wires hole, some covering
On outlet through wires hole, and two wires on coil from outer ring surface out, having respectively entered carries out through wires hole and outlet is worn
String holes, due to spreading out of for this both threads, therefore can form a sulculus on the outer ring surface of coil, and this just can be for limit
Bit slice puts in, and then enables banking stop to go to good position-limiting action to spacing, prevents which from occurring rotating in storage tank
Phenomenon.And the mode of circle distribution, ensure that no matter coil is towards which direction motion, outer ring surface barrier sheet and banking stop
What the resistance of given coil was just as, prevent each uneven and caused part outer ring surface barrier sheet of place force and limit
There is breakage phenomenon in bit slice.
Preferably, first through hole, the base plate of support lower end is distributed with around its center of circle uniform circular on the base plate of support
Face is provided with the salient point that several are offseted with accommodating trench bottom on coil case.
By above-mentioned setting, after fixed base plate is put in the placing trough of coil case, the salient point on skeleton floor
Can offset with the bottom surface of placing trough, so that there is certain gap between base plate of support and placement groove bottom, and work as epoxy
After resin is poured in placing trough, epoxy resin can pass through through hole stream to base plate of support and place between groove bottom, can be very
The fixation of the fixed base plate of good realization,
Preferably, the salient point is corresponded with first through hole and salient point is distributed near the first through hole corresponding to which.
By above-mentioned resin, during processing, in order to material-saving as far as possible, often by coil insulation
Skeleton is made thin thin, and at this time, and after which carry coil and put in placing trough, coil can form crowded to base plate of support
Pressure, the phenomenon for making base plate of support deformation occur；And pass through through hole is arranged on beside first through hole such that it is able to effectively put
Put fixed base plate and deformation occur near first through hole, can effectively ensure that through hole one end and place and have one between trench bottom
Fixed gap, it is ensured that the fine fixation of coil insulation framework.
