Abstract
The utility model relates to an iron core insulation structure. A circular upper penetrating and hollow plate (4) and a circular lower penetrating and hollow plate (3) are respectively arranged at the upper side and the lower side of an iron core (1), at least one layer insulating tape (2) is coated and wound around the periphery of the circular upper penetrating and hollow plate (4), the circular lower penetrating and hollow plate (3), and the iron core (1), and iron core insulation can be realized by the coated insulating tape (2). Because circular penetrating and hollow plates can coat the lead angle of the iron core, poor insulation caused by the breakage of the insulating tape can be avoided.
Description
The utility model relates to a kind of core insulation structure, particularly a kind of core insulation structure that makes the damaged situation of insulating tape when being used to improve magnetive cord and combining with coil because of coil pressure.
Disclose a kind of core structure in the Chinese patent application 97228424.9, magnetive cord places on the insulating tape in this structure, and with the adhesive tape invagination, to coat iron core fully.But the magnetive cord that holds insulating tape is when winding around, and the iron core with lead angle can be big because of the annular core pressure that winds the line, and coefficient of friction is big, slides during coiling, and insulating tape is broken, and then make insulation effect bad.
Main purpose of the present utility model provides a kind ofly at above-mentioned defective improved core insulation structure in addition, and it can make the lead angle of magnetive cord be coated fully, to avoid the insulating tape breakage.
For achieving the above object, the utility model provides a kind of core insulation structure, it has magnetive cord and holds the insulating tape of this iron core, be respectively equipped with on the circle saturating hollow plate under the saturating hollow plate and circle in the upper and lower side of iron core, and saturating hollow plate periphery holds insulating tape under saturating hollow plate, iron core and circle on the circle that group is established, and the insulating tape that is coated is with core insulation.In addition, be at least one deck at the insulating tape described in the utility model.
Now the embodiment shown in conjunction with the accompanying drawings describes structure of the present utility model and function in detail.Wherein:
Fig. 1 is a three-dimensional exploded view of the present utility model;
Fig. 2 is a three-dimensional combination figure of the present utility model;
Fig. 3 is a side of the present utility model cross-sectional schematic
Wherein label 1 is an iron core, and 2 is adhesive tape, and 3 is circular saturating hollow plate down, and 4 is the circular saturating hollow plate of.
As shown in Figure 1, in core insulation structure of the present utility model,,, make saturating hollow plate 4 and circular saturating hollow plate 3 down on the circle that insulation effect is arranged again as thin as a wafer respectively mainly by vacuum punch forming mode according to the shape size of iron core 1.
The surface of magnetive cord 1 does not need to apply with epoxy resin, can reach the effect of primary winding and secondary coil layer insulation.Iron core 1 top is provided with the circular saturating hollow plate 4 of, and the below then is provided with circular saturating hollow plate 3 down.Subsequently, more saturating hollow plate 3, iron core 1 and circular saturating hollow plate 4 under the circle are placed on the insulating tape 2.
Shown in Fig. 2 and 3, the insulating tape 2 of invagination coats circular saturating hollow plate 4, iron core 1 and the circular saturating hollow plate 3 down fully, makes it become an insulator.Circular saturating hollow plate 3 down and circular saturating hollow plate 4 can coat the lead angle of iron core 1 fully.When twining the transformer coil (not shown),,, thereby avoided harmful effect to insulation effect so insulating tape 2 can be because of coiling pressure break because of iron core 1 upper and lower circular saturating hollow plate curved edge coats the lead angle of iron core.
The shape size of circular saturating hollow plate 3 down and circular saturating plate 4 is identical with iron core 1, and they make in vacuum punch forming mode, and are with low cost.Circular saturating hollow plate edge coats iron core 1, and does not need at iron core surface-coated epoxy resin, and gives baking vanish.Owing to deducted the very expensive epoxy resin of cost, make the whole required expense of the utility model reduce greatly, make burden and alleviate, and can Yin Gaowen and change the magnetic of iron core 1.
Core insulation structure of the present utility model mainly is to coat iron cores 1 with saturating hollow plate 3 under the circle and circular saturating hollow plate 4, holds insulating tape 2 again, to reach the effect of insulation.The design of circular saturating hollow plate, not only can coat the lead angle of iron core 1 because of curved edge, can not break because of pressure makes insulating tape 2, guarantee insulation effect, but also because the combination of circular saturating hollow plate, insulating tape 2 can be surrounded with one deck at least, reach double-deck above insulation effect, and assembling is also very convenient.
Claims (2)
1, a kind of core insulation structure, it has magnetive cord (1) and holds the insulating tape (2) of this iron core, of the present utility model being characterised in that: the upper and lower side at iron core (1) is respectively equipped with the circular saturating hollow plate (3) under saturating hollow plate (4) and the circle of, and saturating hollow plate (3) periphery holds insulating tape (2) under saturating hollow plate (4), iron core (1) and circle on the circle that group is established, and the insulating tape that is coated (2) insulate iron core (1).
