Abstract
A kind of open-core type reactor, comprise more than one deck by enamelled wire by spirally-wound multi-turn winding, upper clamping device, lower fixture, fixture and splicing ear, upper clamping device and lower fixture are respectively against upper surface and the lower surface of multi-turn winding, fastening by fixture between upper clamping device and lower fixture, splicing ear comprises the holding part that main part and main body one end are extended, in the holding part that the termination of enamelled wire is contained in splicing ear and with holding part close contact, the outer surface of the holding part of splicing ear and be connected to soldering by supersonic welding between the termination of enamelled wire and the holding part of splicing ear.The termination of the coil of reactor of the present utility model fully contacts with between splicing ear point and does not have space, can ensure coil and splicing ear contact resistance minimum, caloric value is low, make the long service life of whole product, in addition, above-mentioned open-core type reactor is not because arranging iron core, and level of noise reduces greatly, and radiating rate is fast.
Description
Technical field
The utility model relates to a kind of reactor, particularly a kind of open-core type reactor.
Background technology
The reactor of prior art generally comprises iron core, enamelled wire, skeleton, and enamelled wire is wrapped on skeleton, the coil formed on skeleton through enamelled wire winding unshakable in one's determination, and bonding with binding agent between lamination unshakable in one's determination, homogeneity of product is low, noise is high.Between the termination of enamelled wire and splicing ear, the general mode of welding that adopts connects, and complete after welding, there is gap between the termination of enamelled wire and splicing ear, cause contact resistance between enamelled wire and splicing ear large, caloric value is large, affects the useful life of whole product.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of long service life, open-core type reactor that noise is low.
The utility model provides a kind of open-core type reactor, comprise more than one deck by enamelled wire by spirally-wound multi-turn winding, upper clamping device, lower fixture, fixture and splicing ear, described upper clamping device and described lower fixture are respectively against upper surface and the lower surface of described multi-turn winding, fastening by described fixture between described upper clamping device and described lower fixture, the holding part that described splicing ear comprises main part and extends from described main part one end, in the holding part that the termination of described enamelled wire is contained in described splicing ear and with described holding part close contact, the outer surface of the holding part of described splicing ear and be connected to soldering by supersonic welding between the termination of described enamelled wire and the holding part of described splicing ear.
Further, described enamelled wire is aluminium matter enamelled wire or copper paint envelope curve.
Further, described splicing ear is copper splicing ear.
Further, described upper clamping device and lower fixture are the rectangular slab insulated.
Further, described fixture is insulated bolt.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
In the holding part that the termination of the enamelled wire of open-core type reactor of the present utility model is contained in splicing ear and with holding part close contact, the outer surface of the holding part of splicing ear and be connected to soldering by supersonic welding between the termination of enamelled wire and the holding part of splicing ear, so make to divide between enamelled wire and the holding part of splicing ear fully contact and there is no space, can ensure enamelled wire and splicing ear contact resistance minimum, caloric value is low, makes the long service life of whole product.In addition, open-core type reactor of the present utility model, because not arranging iron core, the level of noise of open-core type reactor of the present utility model is reduced greatly, and radiating rate is fast.
Accompanying drawing explanation
Fig. 1 is the perspective view of open-core type reactor of the present utility model.
Fig. 2 is the syndeton schematic diagram of enamelled wire in Fig. 1 and splicing ear.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Refer to Fig. 1-2, the open-core type reactor that the utility model embodiment provides, comprise more than one deck by enamelled wire 1 by spirally-wound multi-turn winding 2, upper clamping device 3, lower fixture 4, fixture 5 and splicing ear 6, upper clamping device 3 and lower fixture 4 are respectively against upper surface and the lower surface of multi-turn winding 2, fastening by fixture 5 between upper clamping device 3 and lower fixture 4, thus multi-turn winding 2 is clamped by clamping device 3 and lower fixture 4.Splicing ear 6 comprises the holding part 64 that main part 62 and main body 62 one end are extended, in the holding part 64 that the termination of enamelled wire 1 is contained in splicing ear 6 and with holding part 64 close contact, the outer surface of the holding part 64 of splicing ear 6 and be connected to soldering 7 by supersonic welding between the termination of enamelled wire 1 and the holding part 64 of splicing ear 6.
In the present embodiment, enamelled wire 1 is aluminium matter enamelled wire or copper paint envelope curve.
In the present embodiment, splicing ear 6 is copper splicing ear.
In the present embodiment, upper clamping device 3 is the rectangular slab insulated with lower fixture 4.
In the present embodiment, fixture 5 is insulated bolt.
The beneficial effects of the utility model are:
In the holding part 64 that the termination of the enamelled wire 1 of open-core type reactor of the present utility model is contained in splicing ear 6 and with holding part 64 close contact, the outer surface of the holding part 64 of splicing ear 6 and be connected to soldering 7 by supersonic welding between the termination of enamelled wire 1 and the holding part 64 of splicing ear 6, so make to divide between enamelled wire 1 and the holding part 64 of splicing ear 6 fully contact and there is no space, can ensure that enamelled wire 1 and splicing ear 6 contact resistance are minimum, caloric value is low, makes the long service life of whole product.In addition, open-core type reactor of the present utility model, because not arranging iron core, the level of noise of open-core type reactor of the present utility model is reduced greatly, and radiating rate is fast.
The foregoing is only embodiment of the present utility model, not thereby the scope of the claims of the present utility model is limited, all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within scope of the present utility model.
