Description

Novel transformer

Technical field

The utility model relates to a kind of transformer, and specifically, it is high to relate to a kind of fenestra utilance, novel planar transformer easy to assembly.

Background technology

Develop rapidly along with the electronic product technology; The volume of portable electronic address such as laptop computer, mobile phone and mobile phone and messaging device is more and more littler; It is more and more too fat to move that traditional transformer just becomes, and it is also just more and more also important that the flat surface transformer technology becomes.Present flat surface transformer comprises skeleton coiling ultra-thin transformer and multi-layer PCB coil ultra-thin transformer, and the former is direct coiling on skeleton, but owing to the existence of skeleton; Can take the certain space of transformer; The fenestra utilance is low, because the space of skeleton is smaller, winding ratio is difficulty in addition; And can cause transformer leakage inductance big, the power delivery loss is big; Though the latter has solved the problem of certain fenestra utilance, because the cost of pcb board is higher, cause the cost of transformer too high, in addition, because the PCB Copper Foil is too thin, loaded current is low, and power is done not quite, and the High-Voltage Insulation intractable.

The utility model content

To above deficiency; The utility model provides a kind of fenestra utilance high; Novel planar transformer easy to assembly, it comprises the core print seat that is provided with magnetic core, and is set in first winding and second winding on the said magnetic core; Said first winding and second winding are respectively the pie of at least one moulding, are provided with insulating barrier between first winding and second winding.

Said pie can be the single planar coil of double plate, also can be the single planar coil of single-deck, also can be many rhizoplanes of double plate coil, also can be many rhizoplanes of single-deck coil, can also be any two kinds or the multiple combination in the above-mentioned coil-type.

Said first winding and second winding can be for arranged in a crossed manner.

Can be between the pie of said first winding for being connected in series, also can be for being connected in parallel.

Can be between the pie of said second winding for being connected in series, also can be for being connected in parallel.

At least one side of said core print seat is provided with the wire casing that of the first winding pin and the second winding pin.

Said pie is annular pie, is positioned at the internal diameter of the internal diameter of top pie less than following pie.

Between the pin of the pin of said first winding and second winding, between the pin of first winding and second winding, between the pin of first winding and second winding, be equipped with the separator of insulation.

Said pie is the enamelled wire coiling.

The beneficial effect of the utility model: the independent moulding of the pie of the utility model, not only coiling is convenient, and the fenestra utilance is high, and leakage inductance is little, and the power delivery loss is little; First winding of the utility model and second winding can be connected respectively in addition or parallel connection, can arbitrarily adjust power output as required; Have, the utility model adopts enamelled wire coiling coiling, can solve the High-Voltage Insulation problem again.

Embodiment

Below in conjunction with accompanying drawing the utility model is further set forth, wherein the direction of the utility model is standard with Fig. 1.

Shown in Fig. 1 or 2, the novel transformer of the utility model comprises core print seat 1, and the centre of core print seat upwards forms cylinder shape magnetic core 11; Core print seat can at least one side have been opened out wire casing 12; Also can not go out wire casing, core print seat can adopt existing techniques in realizing, can be for the wire casing of going out magnetic core (PQ type) being arranged, the wire casing of going out magnetic core (EQ type) is arranged or not having the wire casing of going out magnetic core (EQ type); Be arranged with first winding 3 and second winding 4 on the said magnetic core 11; Said first winding 3 and second winding 4 are respectively the pie of at least one moulding, are provided with insulating barrier 5 between first winding 3 and second winding 4, and the pie of the utility model is paid the utmost attention to and adopted the enamelled wire coiling.In the process of actual assembled, only need to calculate as required the wire circle of first winding 3 and second winding 4 like this, select suitable pie just to combine and to realize.

Pie like Fig. 3,4,5 and 6 first windings 3 and second winding 4 is annular pie, is positioned at the internal diameter of the internal diameter of top pie less than following pie.Pie can be the single planar coil of double plate, also can be the single planar coil of single-deck, also can be many rhizoplanes of double plate coil, also can be many rhizoplanes of single-deck coil, can also be any two kinds or the multiple combination in the above-mentioned coil-type.When being the single-deck planar coil, because the another one joint of coil is positioned at inner ring, in order not influence the fenestra utilance, core print seat 1 preferably adopts to be had the wire casing of going out magnetic core (PQ type) or the wire casing of going out magnetic core (EQ type) is arranged.

In addition, first winding 3 of the utility model and the pie of second winding 4 can still must be provided with dielectric isolation layer between first winding 3 and second winding 4 for arranged in a crossed manner.Can be between the pie of first winding 3 for being connected in series, also can be for being connected in parallel; Can be between the pie of said second winding 4 for being connected in series, also can be for being connected in parallel.Between the pin of the pin of said first winding 3 and second winding 4, between the pin of first winding 3 and second winding 4, between the pin of first winding 3 and second winding 4, be equipped with the separator of insulation.
