Abstract
The utility model discloses a double-trunking electronic transformer. The double-trunking electronic transformer comprises a framework, wherein the left end and the right end of the framework are L-shaped plates, two trunkings are arranged in the middle, a wire is wound on the trunkings to form a winding, pins are respectively arranged at the left side, the right side and under the framework, an insulated rubber tape wraps the winding, an E-shaped magnetic core is fixed at one side of the winding, connection plates extending towards the right are respectively arranged at the upper end and the lower end of the E-shaped magnetic core, and the connection plates are fixed on the framework. The double-trunking electronic transformer is simple in structure, reasonable in design, convenient to manufacture, low in manufacturing cost, good in heat dissipation effect, capable of reducing exchange loss of the winding, simple to operate, good in stability, and long in service life.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of 2 wire casing electronic transformers.
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.Different electronic transformer skeletons is different, and design is different, and the use occasion of electronic transformer is also different.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of 2 wire casing electronic transformers to be provided.
The utility model is achieved through the following technical solutions:
A kind of 2 wire casing electronic transformers, include skeleton, two ends, the described skeleton left and right sides are the L-type plate, the centre is provided with two wire casings, is wound on the wire casing to consist of winding, and the skeleton left and right sides and below are equipped with pin, the described winding outside is surrounded by insulating tape, the E type that once the is fixed with magnetic core of described winding, described E type magnetic core up and down two ends have respectively the connecting plate that extends to the right, and described connecting plate is fixed on the skeleton.
Be connected by glue between described connecting plate and the skeleton.
The utility model has the advantages that: the utility model is simple in structure, and is reasonable in design, easily manufactured, low cost of manufacture, and good heat dissipation effect, and reduce the winding A.C.power loss, and simple to operate, good stability, the life-span is long.
