Abstract

The utility model relates to the technical fields of electronic parts and components, and particularly relates to an ultrathin transformer. The ultrathin transformer comprises a magnetic core and a skeleton, wherein the magnetic core is formed in a manner that an upper cover and a lower cover are matched, a middle post and a semi-sealed container groove around the middle post are arranged inside the magnetic core, and the middle post is oval; the skeleton is of a flat body and embedded in the container groove in the magnetic core, and the middle post of the magnetic core is inserted in a middle hole of the skeleton; leads on the skeleton are wound around the periphery of the middle post of the magnetic core to form a primary coil and a secondary coil of the transformer; and pins respectively connected with the primary coil and the secondary coil are arranged on the skeleton. With the adoption of the technical scheme by the ultrathin transformer, the whole height of the ultrathin transformer is remarkably lowered; and meanwhile, the magnetic conductivity is enhanced, the electromagnetic radiation is weakened, the effect of the transformer is improved, a good radiating effect is achieved, and the insulating property is further enhanced, so that the ultrathin transformer has significant contribution to the miniaturization of a power supply and the intensity of an integrated circuit.

Description

A kind of ultra-thin transformer

Technical field

The utility model relates to technical field of electronic components, especially relates to a kind of ultra-thin transformer.

Background technology

Along with the high speed development of very lagre scale integrated circuit (VLSIC) and printed circuit board surface packing density, the power-supply system miniaturization development that appears as of ultra-thin transformer provides possibility.Yet existing ultra-thin transformer exists that effect is difficult to improve, heat radiation is bad and insulating properties is not good, thereby requires further improvement.

Summary of the invention

It is a kind of simple in structure, scientific and reasonable that the purpose of this utility model is to provide, and the bodily form is little, increases magnetic permeability, and effect is improved, and has the ultra-thin transformer of good heat radiating.

For achieving the above object, the utility model adopts following technical scheme:

A kind of ultra-thin transformer, it includes:

One magnetic core, this magnetic core is combined to form by upper and lower covers, and magnetic core inside is provided with center pillar and centers on the semiclosed tank of center pillar, and center pillar is ellipse shape post;

One skeleton, it is bluff body, and skeleton is embedded at the tank of magnetic core inside, and the center pillar of magnetic core then inserts the mesopore of skeleton; Wire on the skeleton consists of primary coil and the secondary coil of transformer around the center pillar periphery coiling of magnetic core; Skeleton is provided with respectively the pin that is connected with secondary coil with primary coil.

Described magnetic core is flat square, and its upper and lower covers is symmetric body.

Described magnetic core is provided with the breach that leads to semiclosed tank; Increase the heat dissipation characteristics of line bag.

Coiling wire on the described skeleton is enamelled wire, sleeve pipe envelope curve or mix and match.

The utility model adopts technique scheme, so that the whole height of ultra-thin transformer is reduced significantly, meanwhile strengthen magnetic permeability, reduce electromagnetic radiation, promoted the effect of transformer, have great heat radiation effect, insulation property are also further strengthened, and for the closeness of power supply miniaturization and integrated circuit outstanding contribution are arranged.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model one preferred embodiment;

Accompanying drawing 2 is the STRUCTURE DECOMPOSITION schematic diagram of the embodiment of Fig. 1.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further specified:

Consult shown in Fig. 1,2, a kind of ultra-thin transformer described in the utility model, it includes a magnetic core 10, a skeleton 20, and this magnetic core 10 is combined to form by loam cake 11 and lower cover 12, and magnetic core 10 is flat square, and its upper and

lower covers

11,12 is symmetric body.Magnetic core 10 inside are provided with center pillar 13 and around the semiclosed tank 14 of center pillar, center pillar 13 be ellipse shape post, and center pillar 13 maximum outside diameters are towards the open side direction stretching of semiclosed tank 14, and the size of center pillar 13 maximum outside diameters is greater than half of magnetic core 10 length dimension in the same way.Skeleton 20 is bluff body, and skeleton 20 is embedded at the tank 14 of magnetic core 10 inside, 13 mesopores 21 that insert skeleton 20 of the center pillar of magnetic core; Wire 22 on the skeleton 20 consists of primary coil and the secondary coil of transformer around the center pillar 13 peripheries coiling of magnetic core; Skeleton 20 is provided with respectively the pin 23 that is connected with secondary coil with primary coil, and skeleton 20 is insulator, also is provided with to make things convenient for the line mouth 24 that draws outside the wire 22 on skeleton 20, and line mouth 24 also can increase heat radiation function.Coiling wire 22 on the described skeleton is enamelled wire, sleeve pipe envelope curve or mix and match, has good insulation property, promotes useful life.

In the present embodiment, also be provided with the breach 15 that leads to semiclosed tank 14 on the magnetic core 10, increase the heat dissipation characteristics of line bag, be conducive to the coil heat radiation on the skeleton, also make things convenient for simultaneously 22 directed outer drawing of wire, simple in structure, scientific and reasonable, to make easily, cost of investment is low.

Magnetic core 10 of the present utility model and skeleton 20 are flat design, so that the whole height of ultra-thin transformer is reduced significantly, the center pillar 13 of magnetic core 10 is ellipse shape post, increasing magnetic core center pillar area leads to increase magnetic conduction, reduce leakage field, and lengthened the periphery coiling of wire 22 around center pillar 13, strengthen magnetic permeability, reduce electromagnetic radiation, promoted the effect of transformer; Its efficient reaches more than 95%, reaches European Energy Star more than six grades (present six grades is the highest efficiency levels in Europe) by comprehensive collocation line efficiency.

By above-mentioned execution mode, be not difficult to find out that the utility model is preferably a kind of ultra-thin transformer of the less and security performance of whole height, have good functional, radiating effect and insulation property, greatly promoted the ultra-thin transformer scope of application.

Certainly; abovely in conjunction with execution mode the utility model is described in detail; only be explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with technique understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection range of the present utility model.
