Abstract
The utility model is related to a kind of fixed transformers of bar magnet, including skeleton, bar magnet, interior parting bead, outer parting bead, it is pasted with three interior parting beads along the position of the bar magnet outer circumference surface trisection of paint-dipping drying processing, interior parting bead length is identical as the one third of bar magnet length, outer parting bead is pasted with outside interior parting bead, outer parting bead length is identical as the half of bar magnet length, keep interior parting bead identical as the half in bar magnet gap for skeleton as the overall thickness of outer parting bead, the bar magnet for posting parting bead is placed in the centre bore of skeleton.Advantageous effect is, bar magnet ensure that while fixation with skeleton gap, embedding effect is good, reduces noise caused by bar magnet vibration, strengthens the insulating properties between bar magnet and skeleton.
Description
Technical field
The utility model is related to a kind of transformer, more particularly to a kind of fixed transformer of bar magnet.
Background technology
Skeleton and the magnetic core component part important as transformer, the cooperation reasonable for structure between them are even more important, and
In actual design in order to ensure the requirement of performance, needs to do a little concessions in structure design, just will appear and be installed in skeleton
Magnetic core cannot be bonded very much, especially bar magnet installs that the space that the skeleton trepanning of bar magnet reserves is slightly larger, just it cannot be guaranteed that bar magnet
Verticality, such disadvantage directly affect the quality of transformer.
Invention content
In view of the problems existing in the prior art, the utility model provides a kind of fixed transformer of bar magnet, particular technique side
Case is a kind of fixed transformer of bar magnet, including skeleton, bar magnet, interior every, outer parting bead, it is characterised in that：Along paint-dipping drying processing
Bar magnet outer circumference surface trisection position on be pasted with three interior parting beads, the one third phase of interior parting bead length and bar magnet length
Together, outer parting bead is pasted with outside interior parting bead, outer parting bead length is identical as the half of bar magnet length, make interior parting bead with outside every
The overall thickness of item is that skeleton is identical as the half in bar magnet gap, and the bar magnet for posting parting bead is placed in the centre bore of skeleton.
The utility model has the beneficial effects that bar magnet fix while ensure that with skeleton gap, embedding effect is good, reduce
Noise caused by bar magnet vibration, strengthens the insulating properties between bar magnet and skeleton.
Description of the drawings
Fig. 1 is the structure sectional view of the utility model；
Fig. 2 is the bar magnet structure chart of the utility model；
Fig. 3 is the skeleton structure diagram that the utility model is equipped with bar magnet.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
Embodiment 1
As shown in Figure 1, 2, 3, by taking a kind of beauty care device high voltage package as an example, including skeleton 1, ferrite bar 2, interior parting bead 3,
Outer parting bead 4, shell 5, φ 0.05*1P polyurethane enamelled wires I 6, φ 0.47*P polyurethane enamelled wires II 7, casting glue 8, the bone
Frame 1 has seven slot positions, and the circle of the first six slot coiling φ 0.05*1P polyurethane enamelled wires I 63600 is secondary coil 6, the last one slot
Coiling φ 0.47*P polyurethane enamelled wires II are that 17.5 circles are primary coil 7, the screw rod of the bottom insertion M3 of skeleton 1, for connecting
Shell 5 is connect, the complete coil of coiling is packed into shell 5, positive pressure is put to bottom, fastens M3 nuts with dedicated tool, coil is not loose
It is dynamic, it is seamless between nut and shell 5；Since the center bore of skeleton 1 is more than the amount of diameter 2mm of bar magnet 2 or so so that bar magnet
Meeting run-off the straight after loading frame center slot, the inductance to bring is bad, and voltage waveform is unstable, has the fraction defectives such as noise generation
Generation.Therefore, three interior parting beads 3 are pasted with along the position of the 2 outer circumference surface trisection of bar magnet of paint-dipping drying processing, it is interior every
3 length of item is identical as the one third of 2 length of bar magnet, and outer parting bead 4,4 length of outer parting bead and bar magnet are pasted in 3 outside of interior parting bead
The half of 2 length is identical, makes the overall thickness about 1mm of interior parting bead 3 and outer parting bead 4, and the bar magnet 2 for posting parting bead is inserted into skeleton 1
Centre bore in.Enter baking oven later to preheat, be finally potted with casting glue 8.After cured carry out appearance processing, finished product into
Row performance test, the output voltage waveforms of test are without apparent burr, and without apparent shake, noise without exception is certified products.
