Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
Referring to figs. 1 through Fig. 3, a kind of stitch reactor described in the utility model, comprises iron core 1, insulation framework 2, coil windings 3, insulating protective layer 4, insulating base 5.Iron core 1 is fixedly connected with insulation framework 2.Described insulation framework 2 inner hollow, and both ends open, this insulation framework 2 is set in the periphery of iron core 1 regularly.Described coil windings 3 is the periphery that wire 31 that an outer surface has an insulating barrier is wrapped in insulation framework 2 regularly, and the two ends of this wire 31 are stretched out from the lower surface of insulation framework 2.Described insulating protective layer 4 is coated on the periphery of described coil windings 3, and it can be used for protection coil windings 3 and coil windings 3 is fixed in insulation framework 2 further.Described insulating base 5 is fixed on the lower end of described iron core 1, and this insulating base 5 offers the perforation (figure does not mark) for described wire 31 two ends.The two ends of described wire 31 are through perforation, and the wire 31 being positioned at insulating base 5 lower end forms stitch 6, the periphery naked layer of this stitch 6.Described stitch 6 is for being connected with other electronic components.
Because described stitch 6 is the two ends of wire 31 described in coil windings 3, namely this stitch 6 is be the part in coil windings 3 in fact, and therefore described stitch 6 is without the need to coming to re-start with coil windings 3 to be connected by other connecting line.This stitch 6 substitutes copper tip of the prior art, and namely abridged connects copper tip in addition, so the connecting line in the abridged external world and copper tip, thus decreases production cost.
Described iron core 1 comprises the first iron core 11, second iron core 12 and air gap pad 13.The described lower surface of the first iron core 11 and the upper surface of air gap pad 13 offset, and the described upper surface of the second iron core 12 and the lower surface of air gap pad 13 offset.Described air gap pad 13 interts in the inside of insulation framework 2.This air gap pad 13 can be made up of materials such as insulating paper, insulating resin or potteries, plays the effect of spacer member.Lower surface and the described insulating base 5 of described second iron core 12 are fixed.
Gap is formed between described insulation framework 2 and described insulating base 5.The material of this insulation framework 2 can be not identical with the material of insulating base 5.
As shown in Figure 4, described insulating base 5 can be made at least one in epoxy plate, nylon, timber, polyvinyl chloride, crosslinked polyethylene, halogen-free polyolefin or cross-linked polyolefin etc. has the material better insulated.This insulating base 5 is fixedly connected with iron core 1 by the first adhesive 7.In order to improve stability when this insulating base 5 is connected with iron core 1, the upper surface of this insulating base 5 can offer the concave shaped space 51 for installing iron core.By the first adhesive 7, the diapire 510 of concave shaped space 51 and sidewall 511 are all fixed with iron core 1 gluing.This concave shaped space 51 increases the area that this insulating base 5 is fixedly connected with iron core 1, and the heel of both connections is stablized.
In order to improve the stability of stitch 6, perforation place of described insulating base 5 is provided with the second adhesive 8, and this second adhesive 8 is positioned at the upper surface of insulating base 5, and fixes with the insulating barrier gluing of described wire 31 outer surface simultaneously.Described first adhesive 7 is identical with the material of the second adhesive 8 all can be epoxy glue of the prior art.Described insulating base 5 can also offer the coupling hole (not shown) for other objects affixed, so can realize more firm being installed in cabinet of stitch reactor of the present utility model.
In order to prevent stitch 6 oxidized, the outer surface of described stitch 6 is coated with tin layers (figure does not mark) equably.
The utility model also provides a kind of preparation method preparing stitch reactor described in above embodiment:
Step S1, interts regularly by iron core 1 in insulation framework 2;
Step S2, the wire 31 outer surface with insulating barrier is wrapped in the periphery of insulation framework 2 and forms coil windings 3, and is stretched out the below of the two ends of this wire 31 by insulation framework 2;
Step S3, is fixed on the lower surface of iron core 1 by adhesive by insulating base 5;
Step S4, on insulating base, 5 offer perforation;
