Abstract
An inductance coil comprises an annular magnetic core (1) and a coil body (2) wound on the magnetic core (1), and the magnetic core (1) and the coil body (2) are fixed on a plastic base (3) through epoxy resin black rubber (4). Compared with the prior art, the inductance coil can be fixed on a circuit board well, and is firm and reliable in structure, low in failure rate and long in service life.
Description
Technical field
The utility model relates to a kind of inductance coil, relates in particular to the inductance coil for the UPS uninterrupted power supply.
Background technology
In the UPS uninterrupted power supply, inductance coil is to exchanging the current limiting effect, and it can form high pass or low pass filter, phase-shift circuit and resonant circuit etc. with resistor or capacitor; Transformer can carry out AC coupled, transformation, unsteady flow and impedance transformation etc.At present, the many employings of this type of inductance coil directly are welded on circuit board, and this structure is insecure, and on inductance coil, the heat radiation of magnetic core is bad, easily breaks down, and useful life is short.
The utility model content
The purpose of this utility model is to propose a kind of novel inductance coil, can well fix in the circuit board, and sound construction is reliable, failure rate is low, long service life.
For reaching this purpose, the utility model by the following technical solutions.
A kind of inductance coil, comprise annular magnetic core and be wrapped in the coil on magnetic core, and wherein said magnetic core and coil are fixed on plastic base by the black glue of epoxy resin.
In above-mentioned inductance coil, described plastic base below is provided with a plurality of auxiliary stitch, and described coil is electrically connected on described auxiliary stitch.
Usually, in above-mentioned inductance coil, described plastic base below is provided with 4～6 auxiliary stitch.
Preferably, in above-mentioned inductance coil, can by the anchor ring of the magnetic core of described annular, be further perpendicular to described plastic base plane layout.So the magnetic core heat dispersion is better, not fragile, can increase the service life.
In above-mentioned inductance coil, described epoxy resin friction tape is the upper surface of described plastic base completely, but is no more than the surrounding of described plastic base.
In above-mentioned inductance coil, described coil line is enamelled wire.
In above-mentioned inductance coil, the outside of described coil and magnetic core is coated with insulating tape.
Compared with the existing technology, the inductance coil that the utility model provides, can well be fixed on circuit board, and sound construction is reliable, failure rate is low, long service life.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment inductance coil structural representation.
Fig. 2 is the schematic top plan view of plastic base described in the utility model.
Label declaration: 1-toroidal core; 2-coil; 3-plastic base; 4-epoxy resin is deceived glue; 5-auxiliary stitch.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.Should be appreciated that accompanying drawing is not in strict accordance with scale, and wherein may have default that some one of ordinary skill in the art will appreciate that.At embodiment, describe in process, for saving space, known technology will be done some omissions.
With reference to accompanying drawing 1, a kind of inductance coil, comprise annular magnetic core 1 and be wrapped in the coil 2 on magnetic core 1, and wherein said magnetic core 1 and coil 2 are fixed on plastic base 3 by the black glue 4 of epoxy resin.Can prepare with the following method by above-mentioned inductance coil, enamelled wire is wrapped on toroidal core 1 and forms coil 2, toroidal core 1 test of enamelled wire will have been twined, the sample of test passes shears lead-foot-line and sloughs insulating varnish, scolding tin, then it is contained on stand-by plastic base 3, then the toroidal core 1 that has twined enamelled wire and plastic base 3 junctions are filled to the black glue 4 of epoxy resin; The vacancy of the black concordant plastic base 3 of glue 4 of epoxy resin; The black glue 4 of epoxy resin can not exceed the inboard of plastic base 3, finally toasts 105 ℃ and makes adhesive curing in 1.5 hours.A plurality of auxiliary stitch 5 and coil 2 electrical connections can be housed on plastic base 3.Can only need to assist stitch 5 to be welded on circuit board like this, make the welding circuit board operation convenient.Auxiliary stitch 5 is preferably 4～6.
In a preferred embodiment of the present utility model, the anchor ring of the toroidal core 1 in inductance coil is perpendicular to fixing its plastic base 3 plane layouts.So magnetic core 1 heat dispersion is better, not fragile, can also increase the service life.
In another preferred embodiment of the present utility model, the black glue 4 of epoxy resin that inductor wire encloses fixation is covered with the upper surface of plastic base 3, but is no more than the surrounding of plastic base 3.
In another preferred embodiment of the present utility model, the coil 2 on inductance coil and the outside of magnetic core 1 are coated with insulating tape.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection range.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, within these modes all will fall into protection range of the present utility model.
