Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in the figure, the monolithic devices magnetic bobbin core of the utility model, including the plate stem 4 as support frame, with
And the silicon steel sheet 1 of stem front and rear sides is overlayed, air gap 2 is formed between the silicon steel sheet, tree is cast in the air gap
Fat, resin are epoxy resin, are integrated with stem and silicon steel sheet cast.That is, except being silicon steel sheet elsewhere at air gap,
Silicon steel sheet includes the short silicon steel sheet between the lengthy motion picture and air gap of the left and right sides, and the silicon steel sheet and stem of heap poststack form cross circular section
Shape, this similarly to the prior art, not reinflated description herein.
Air gap plate is filled in air gap in the prior art because filling the end face out-of-flatness of air gap plate caused by it is above-mentioned it is many not
It is good, it is poured in the utility model using fillings such as epoxy resin, pours and be integrated with silicon steel sheet, air gap and silicon after pouring into an integrated entity
Steel disc is in close contact, and no longer there are gap, the part of air gap is filled using resin-cast, and without carrying out the sanction of air gap plate in advance
Polishing is cut, reduces substantial amounts of man-hour, reduces the uneven situation for generating noise of the possibility for generating Errors Catastrophic and end face, this
Kind structure is not only easy to operate but also saves man-hour, and the low noise of iron core, good heat dissipation, substantially increases the performance of product.
Specifically, the stem in the middle part of the iron core and silicon steel sheet are poured and are integrated, i.e., are formed in silicon steel loop week outer
Side is cylindrical resin bed 3, and the thickness of the resin bed is in 1-3mm, such as 2mm.The upper and lower ends of the iron core point
Binding strap 5 is not provided with.
Binding strap is bound in the place of no cast, and cast is to pour to be at iron yoke above and below the center of stem, stem
It does not pour into a mould, it is exactly in order to tighten silicon steel sheet, due to air gap plate and point of silicon steel sheet when former deflation gap plate to bind it
It is the place do not poured into a mould up and down at binding three so binding strap is whole take-up straps from top to bottom from not being integral, distance
Is exactly the effect fastened at uniform scattered binding three, after the stem resin of iron core pours into an integrated entity air gap portion filling,
Binding strap is twined so that the heat dissipation capacity of iron core substantially reduces without whole again, improves the performance of product.
Meanwhile the invention also discloses a kind of frock for being used to prepare the monolithic devices magnetic bobbin core, including two
A baffle matched in the insertion air gap, the supporting mechanism such as epoxy plate and to the baffle as described in positioning are described
Supporting mechanism include outer square tube 6 and be matchingly inserted into the interior square tube 7 of the outer square tube, the interior square tube and foreign side
Retaining mechanism is provided between pipe.Specifically, the retaining mechanism be correspondingly arranged it is multiple fixed in interior square tube and outer square tube
Position hole 8 and positioning pin in the insertion location hole can be matched.
The internal diameter of interior square tube and outer square tube is different, can be plugged together between them, in interior square tube and outer square tube
Location hole is opened up respectively and two groups of location holes and spacing are different, by being inserted into a positioning pin, can be combined into different length.
In use, frock is put at air gap block, sample block baffle, adjustment distance to design size, the epoxy plate top of both sides are placed in both sides
Firmly silicon steel sheet, blow-down position lock extremely can, be mainly ensuring that air gap distance, further, to prevent to move,
Locating effect is improved, magnetic stripe or magnetic patch are embedded in the outer square tube to be adsorbed with the stem.After the completion of stem closed assembly,
First surface brushes solidified paint and is relatively fixed silicon steel sheet, and curable lacquer layer is coated in the resin bed.The i.e. described resin
Layer is located on the outside of the curable lacquer layer；The positioning pin of the frock of adjustable distance is pulled out afterwards, shortens distance, frock and gear
Plate can take out, and when taking-up will not disturb, and cause silicon steel sheet change in location, assembly precision is effectively ensured.
Specifically, construction procedure is
1) baffle corresponding with air gap and frock are chosen；
2) iron core column closed assembly is carried out, sample block baffle and frock are put at air gap when being stacked at air gap, to occupy
The position of air gap；
3) after the complete closed assembly of stem, the fixed paint of first coating is silicon steel sheet to be fixed, taking-up sample block baffle and frock,
Need the upper polyfluortetraethylene plate of winding outside the stem poured into a mould (can Reusability)；
4) deployed room temperature resin carries out normal temperature and pressure cast with room temperature resin, air gap gap and stem is carried out whole
Body is poured into a mould, and all gaps are all poured into a mould together, form an entirety；
5) after resin solidification, polyfluortetraethylene plate of dismantling, with dilute 3 places for tying up iron core top and bottom of binding strap, often
Two layers of place's binding, it is fixed.
Meanwhile the monolithic devices magnetic bobbin core of the utility model is preferably applied to magnetic-bias arc-suppression coil, other structures with it is existing
Technology is similar, herein not reinflated description.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these change
