Description
Technical field
The utility model relates to electronic component technology field, refers to especially a kind of inductor.
Background technology
Inductor is to be the element that magnetic energy stores electric energy conversion.The structure of inductor is similar to transformer, but only has a winding.When having electric current to pass through in wire coil, the surrounding of wire coil will produce magnetic field.When in coil, electric current changes, its magnetic field around also produces corresponding variation.But wire coil can produce a large amount of heat when work, the continuous rising meeting of temperature is altered for making the electrical conductivity of metal material of wire coil, and the change of electrical conductivity will change simultaneously, the resistance of wire coil, the electric current flowing through, thus wire coil magnetic field around changed.In addition, wire coil under the operating state in high temperature, easily damages for a long time.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of inductor, by changing its structure, on wire coil, increase radiating fin, make wire coil perfect heat-dissipating, reduce the electrical conductivity of wire coil as far as possible, keep wire coil magnetic field around as far as possible, and increased the useful life of wire coil.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of inductor, comprise base, housing, wire coil and magnetic core, described wire coil, magnetic core and housing are all fixed on base, described magnetic core is arranged in wire coil, described magnetic core and wire coil are all positioned at housing, described wire coil consists of upper coil and lower coil, between described upper coil and lower coil, be provided with radiating fin, described upper overhang and lower coil end all through housing to hull outside, the direction of current flow of described upper coil and lower coil is identical.
As preferably, the end of described upper overhang and lower coil is connected by conductive plate, and the end of described upper overhang and lower coil is connected by conductive plate, is all connected with terminals on described conductive plate.
As preferably, described radiating fin is the heat dissipation equipment that insulating material is made.
As preferably, the side of described housing is equipped with ventilation hole.
The utility model is simple in structure, and technology is reasonable, produce simple, with low cost, the favorable working performance that is magnetic energy by electric energy conversion, and increased useful life of inductor.
