Description
Technical field
The present invention relates to a kind of electromagnetic coil, coil insulation framework and the modified nylon materials for preparing the skeleton.
Background technology
Existing electromagnetic coil, is mainly made of coil case and coil, and coil case one end is equipped with concentric with it set
The placing groove of coil is put and is used to place, and in order to make to insulate between coil and limiting shell, existing way is past
Past to select to wind non-woven fabrics in the outside of coil, structure is as shown in Figure 9.Its assembling process is：First in the outer bread of coil 8
Non-woven fabrics 10 is wrapped, then the coil 8 coated is placed into placing groove 91, asphalt mixtures modified by epoxy resin is then poured into placing groove
Fat, you can realize the fixation between coil 8 and coil case 9.
Above-mentioned electromagnetic coil structure is simple, but its existing drawback is during electromagnetic coil is assembled, to need
One circle circle toward winding non-woven fabrics 10 on coil 8, it is low so as to cause packaging efficiency.
Invention content
The first object of the present invention is to provide a kind of coil insulation framework that can quickly realize assembling, 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, packet
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 blocking respectively along it
Piece and outer ring surface barrier sheet form to place coil between the outer ring surface barrier sheet, base plate of support and inner ring surface barrier sheet
Storage tank.
By above-mentioned setting, coil is first put into storage tank by this coil insulation framework during use, at this time
Inner ring surface barrier sheet can play coil good position-limiting action, while also coil can be played very with outer ring surface barrier sheet
Good clamping action.In addition, after in the placing groove 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 coil case effectively being avoided electrification occur now to keeping apart with coil case
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 into storage tank, the outer ring surface of inner ring surface barrier sheet can be with coil
Inner ring surface fit together well, the outer ring surface that the inner ring surface of outer ring surface barrier sheet can be good at coil is fitted in one
It rises, effectively increases the contact area between inside and outside anchor ring barrier sheet and coil, and after increasing contact area, inner and outer rings
Between face and coil there is larger frictional force, coil is avoided to be detached 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 moves；The presence of inner ring surface barrier sheet can also play iris action between coil and coil case simultaneously,
Prevent coil case from charging；In addition, inner ring surface barrier sheet is divided into multi-disc, relative to an annular barrier sheet, Neng Gouyou
The saving material 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 moves；The presence of inner ring surface barrier sheet can also play iris action between coil and coil case simultaneously,
Prevent coil case from charging；In addition, outer ring surface barrier sheet is divided into multi-disc, relative to an annular barrier sheet, Neng Gouyou
The saving material of effect reduces production cost；And the diameter of outer ring surface is the diameter for being greater than inner ring surface, therefore is also just not required to
The radian of outer ring surface barrier sheet is arranged to identical with the radian of inner ring surface barrier sheet, can further save material, reduced
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 can be covered almost
Entire circular arc, therefore moved regardless of coil along which direction of horizontal direction, inside and outside barrier sheet can generate one to coil
Fixed barrier effect realizes the good position-limiting action to coil.
Preferably, the base plate of support be equipped with threading hole, the threading hole side wall be equipped with by threading hole be separated into
The partition board of line threading hole and outlet threading hole upwardly extends to form banking stop at the base plate of support outer ring surface face partition board, institute
The width for stating banking stop is more than the width of partition board but is less than the width of threading 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 threading hole and there is threading hole and separated by partition board, it can be effectively by inlet wire
The phenomenon that threading hole and the conducting wire occurred between threading hole separate, prevent short circuit；And work as banking stop along itself and fixation
The connecting line of bottom plate connection is turned over when turn 90 degrees, and a banking stop part is covered on inlet wire threading hole, some covering
On outlet threading hole, and two conducting wires on coil from outer ring surface come out, have respectively entered and carry out threading hole and outlet and wear
String holes due to the outflow of this both threads, can form a sulculus on the outer ring surface of coil, and this just can be for limit
Bit slice puts in, and then banking stop is enable to go to good position-limiting action to limiting, prevents it from being rotated in storage tank
The phenomenon that.And the mode of circle distribution, it can ensure no matter coil is moved towards which direction, outer ring surface barrier sheet and banking stop
The resistance of given coil is the same, part outer ring surface barrier sheet and limit caused by preventing each place force uneven
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 equipped with several salient points to offset with housing trench bottom on coil case.
By above-mentioned setting, after will fix bottom plate and be put into the placing groove of coil case, the salient point on skeleton floor
It can offset with the bottom surface of placing groove, so as to make between base plate of support and placement groove bottom there are certain gap, and work as epoxy
It, can be very between epoxy resin can be flowed to base plate of support by through-hole and place groove bottom after resin is poured into placing groove
The fixation of the fixed bottom plate of good realization,
Preferably, the salient point is corresponded with first through hole and salient point is distributed close to the first through hole corresponding to it.
By above-mentioned resin, during processing, in order to save material as far as possible, often coil is insulated
Skeleton is made thin, and at this time, after being put into placing groove which carry coil, coil can form base plate of support crowded
Pressure, it is described that base plate of support is made the phenomenon that deformation occur；And by the way that through-hole is arranged on beside first through hole, so as to effectively put
It puts fixed bottom plate and occurs deformation near first through hole, can effectively ensure that there are one between through-hole one end and placement trench bottom
