Abstract
The utility model relates to an inductive device which comprises an iron core, a coil and a terminal. The section of the iron core is of an E type, two openings of the E type are opposite, the inside and the outside of the iron core are provided with cooling fins, the coil winds a center column of the iron core, and the terminal is connected with the coil. Due to the fact that the inside and the outside of the iron core are provided with the cooling fins made of copper sheets, heat in the inductive device can be dissipated rapidly, safety and reliability of product use are enhanced, the service life of a product is prolonged, and loss of users is reduced.
Description
Technical field
The utility model relates to a kind of inductance component.
Background technology
Existing inductance component, be, in the outside of inductance component, metal fin is installed, by fin, externally dispel the heat, this radiator structure, can only fall apart fast except the heat of inductance component outside, the heat of inductance component inside is difficult to shed, thus existing inductance component under the state of long-term work, internal temperature is too high, cause the insulation system of inductance component inside impaired, shorten greatly the useful life of inductance component, and had great potential safety hazard, will bring loss to user.
Utility model content
The purpose of this utility model is to overcome the defect that prior art exists, and a kind of safe and reliable inductance component is provided.
The technical scheme that realizes the utility model object is: a kind of inductance component, comprise iron core, coil and terminals, the cross section of described iron core is two E types that opening is relative, core interior, outside are all provided with fin, described coil winding is on the newel of iron core, and described terminals are connected with coil.
Further, described fin is connected to form by fin skeleton and the cooling fin fin base of E type, and E type fin skeleton gos deep into core interior, fixing with the laminating of E shaped iron core cross section, and cooling fin fin base and core exterior surface laminating are fixing.
Further, described fin is copper sheet, and described coil is formed by copper strips or copper wire winding.
Further, on described newel, cover has coil rack, and described coil winding is on coil rack.
The utlity model has positive effect: the utility model is at the inside and outside fin that is all provided with of iron core, and select copper sheet as fin, make the heat of inductance component inside can very fast shedding, fail safe, the reliability of product have been strengthened, in the useful life of having improved product, to user, reduced loss.
