Abstract
The utility model discloses an electronic transformer which comprises a framework and a winding which is formed by copper wires winded on a framework trunking. The framework is narrow in the left side and wide in the right side. The trunking is placed in the middle portion. The left side below the framework and the right side below the framework are respectively provided with metal stitches. The left side of the framework and the right side of the framework are respectively provided with pins. A magnetic core is placed outside the winding on the framework. The outsides of both the winding and the magnetic core are covered with insulating rubber tape. The winding and the magnetic core are fixed through glue. The electronic transformer is simple in structure, rational in design, low in manufacturing difficulty, good in heat dissipation effect and capable of reducing alternating current losses of the winding.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of electronic transformer.
Background technology
Electronic transformer, having alternating voltage with civil power and change into behind the direct current at the electronic installation that consists of a kind of high-frequency ac voltage output by semiconductor switch device and electronic component and high frequency transformer winding, also is a kind of friendship orthogonal inverter circuit of telling about in theory of electronics.In simple terms, it mainly is comprised of high frequency transformer magnetic core (iron core) and two or more coils, and they do not change the position mutually, from one or more electric loop, by the electromagnetic induction effect, be transformed into alternating voltage and electric current by alternating electromotive force.And at the output of high frequency transformer, to one or more electricity consumption loop, supply with high-frequency ac or the direct current of different electric pressures.List transformer of the prior art causes manufacturing process high because structural design is unreasonable, and radiating effect is poor, and the winding A.C.power loss is high.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of electronic transformer of good heat dissipation effect to be provided.
The utility model is achieved through the following technical solutions:
A kind of electronic transformer, include skeleton and be wound on the winding that consists of on the skeleton wire casing by copper cash, described skeleton is that narrow the right, the left side is wide, wire casing is located at the centre position, the left and right sides, described skeleton below is respectively equipped with the metal stitch, and the skeleton left and right sides is respectively equipped with pin, and the winding outside is equipped with magnetic core on the described skeleton, winding and the magnetic core outside all are surrounded by insulating tape, fix by glue between winding and the magnetic core.
Described magnetic core is rectangle.
The utility model has the advantages that: the utility model is simple in structure, and is reasonable in design, and manufacture difficulty is low, good heat dissipation effect, and reduce the winding A.C.power loss.
Description of drawings
Fig. 1 is the utility model vertical view.
Fig. 2 is the utility model front view.
Embodiment
As shown in Figure 1, 2, a kind of electronic transformer, include skeleton 1 and be wound on the winding 3 that consists of on skeleton 1 wire casing by copper cash 2, described skeleton 1 is that narrow the right, the left side is wide, and wire casing is located at the centre position, and the left and right sides, described skeleton 1 below is respectively equipped with metal stitch 4, the skeleton left and right sides is respectively equipped with pin 8, winding 3 outsides are equipped with magnetic core 5 on the described skeleton 1, and winding 3 all is surrounded by insulating tape 6 with magnetic core 5 outsides, and are fixing by glue 7 between winding 3 and the magnetic core 5.
Described magnetic core 5 is rectangle.
