Abstract
The utility model relates to the technical field of transformer equipment, in particular to a transformer with a shielding belt. The transformer comprises a transformer body, wherein the transformer body is provided with coil windings and the shielding belt; and the shielding belt coats the coil windings and is arranged on the outer surface of the transformer body in a tensioning mode. Compared with the prior art, the transformer has the advantages that leakage flux frequently generated by the isolation transformer body can be effectively shielded; and during operation, electromagnetic interference of the coil windings and an iron core on other surrounding components can be effectively reduced and even eliminated, so that normal and high-efficiency operation of a circuit can be maintained.
Description
Technical field
The utility model relates to the transformer technology field, particularly relates to a kind of transformer that is provided with the mask tape.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member comprises one-level coil windings, secondary coil winding and iron core.In electric equipment and radio-circuit, be commonly used for lifting voltage, matched impedance, safety isolation etc.
Along with the development of social electronics industry, the application of transformer is more and more extensive, and is also more and more important.Yet leakage flux usually occurs in transformer in application process at present, will produce electromagnetic interference, particularly having the greatest impact to low-power amplifier to other components and parts when leakage field passes peripheral circuit.
The utility model content
The purpose of this utility model is to avoid weak point of the prior art and a kind of transformer that is provided with the mask tape that can reduce peripheral components and parts electromagnetic interference is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of transformer that is provided with the mask tape comprises transformer body, and transformer body is provided with coil windings, is provided with the mask tape, and the mask tape coats coil windings, also tension is arranged at the outer surface of transformer body.
Wherein, the first end of mask tape is fixedly installed on a surface of transformer body, and the second end winding transformer body one week of mask tape also is connected with the first end of mask tape.
Wherein, the first end of mask tape is connected by argon arc welding spot welding with the second end of mask tape.
Wherein, the mask tape is set to the silicon steel mask tape.
Wherein, the mask tape is set to the copper foils for shielding band.
The beneficial effects of the utility model: a kind of transformer that is provided with the mask tape, comprise transformer body, transformer body is provided with coil windings, is provided with the mask tape, and the mask tape coats coil windings, also tension is arranged at the outer surface of transformer body.Compared with prior art, mask tape of the present utility model can effectively shield the leakage flux that the isolating transformer body generates, when work can effectively reduce even eliminate coil windings and iron core to around the electromagnetic interference of other components and parts, thereby the circuit maintenance is worked normally and efficiently.

Embodiment
The utility model is described in further detail with the following Examples.
A kind of transformer that is provided with the mask tape as shown in Figure 1 to Figure 3, comprises transformer body 2, and transformer body 2 is provided with coil windings 21, is provided with mask tape 1, and the mask tape 1 of the present embodiment is set to the silicon steel mask tape.In the present embodiment, mask tape 1 coats coil windings 21, also tension is arranged at the outer surface of transformer body 2.Wherein, the first end of mask tape 1 is fixedly installed on a surface of transformer body 2, and 2 one weeks of the second end winding transformer body of mask tape 1 are connected with the first end of mask tape 1, and the first end of mask tape 1 is connected by argon arc welding spot welding with the second end of mask tape 1.
The a kind of of the present embodiment is provided with the transformer of mask tape 1 because the silicon steel mask tape being installed, and mask tape 1 can effectively shield the long-living leakage flux of isolating transformer body 2, therefore when work, can effectively reduce, even eliminate the electromagnetic interference of other components and parts around 22 pairs of coil windings 21 and the iron cores, make circuit keep working normally and efficiently.
The present embodiment a kind of is provided with the transformer of mask tape and the difference of embodiment 1 is, the mask tape 1 of the present embodiment is set to the copper foils for shielding band.Other structure and the principle of the present embodiment are identical with embodiment 1, do not repeat them here.
Should be noted that at last; above embodiment only is used for the explanation the technical solution of the utility model but not to the restriction of the utility model protection range; although with reference to preferred embodiment the utility model has been done detailed description; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
