Description
Technical field
The utility model relates to a kind of reactor, particularly a kind of open-core type reactor.
Background technology
The air core reactor of prior art is the hollow core structure that enamelled wire is circumferentially coiled into, enamelled wire between each winding of this core structure fits together closely, there is no ventilation air duct, be unfavorable for the heat radiation of reactor self, cause the useful life of reactor short.In addition, between the termination of enamelled wire and splicing ear, the general mode of welding that adopts connects, and completes after welding, gap is there is 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 open-core type reactor of long service life.
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, often enclose the cross bolster arranged between layers along direction, the center of circle of winding, 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:
Open-core type reactor of the present utility model is owing to being provided with cross bolster, and make air core reactor itself produce horizontal air channel, its perfect heat-dissipating, extends the useful life of reactor.In addition, 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.
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 and Fig. 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.Often enclose the cross bolster 8 arranged between layers along direction, the center of circle of winding 2.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 9 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:
Open-core type reactor of the present utility model is owing to being provided with cross bolster 8, and make air core reactor itself produce horizontal air channel, its perfect heat-dissipating, extends the useful life of reactor.In addition, 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 6 of splicing ear 6 and be connected to soldering 9 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.
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.
