Abstract

The utility model relates to an efficient transformer which comprises two casings identical in structure, a fastening piece locking the two casings, and a coil arranged between the casings. Each casing comprises a substrate, a lateral plate upwardly arranged at the edge of the substrate, and an iron core upwardly arranged in the center of the substrate; and an accommodation space is formed between the iron core and the lateral plate for accommodating the coil. By adopting the separate casings, arranging the iron cores on the casings, and accommodating the coil between the iron cores and the lateral plates, the size of the entire transformer is greatly reduced, and the conversion efficiency of the entire transformer is improved.

Description

Highly effective transformer

Technical field

The utility model relates to transformer, more particularly, relates to a kind of highly effective transformer that can be used in the power circuit.

Background technology

In existing power circuit, the transformer components and parts that are absolutely necessary are realized the conversion of voltage by transformer, thereby are obtained desirable voltage, electric current etc.Existing transformer generally include skeleton, winding at the coil of skeleton periphery, be fixed on the iron core of skeleton periphery and the clip of fixing whole transformer.The volume of the transformer of this structure is bigger usually, is not suitable for the use of miniature circuit; And the conversion efficiency of voltage is lower, and power consumption is big.

The utility model content

The technical problems to be solved in the utility model is, a kind of rational in infrastructure, highly effective transformer that conversion efficiency is high is provided.

The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of highly effective transformer, comprise two shells with same structure, with the securing member of described two shells locking and be arranged on coil between the described shell;

Each described shell comprises substrate, the side plate that upwards is provided with at the edge of described substrate and the iron core that upwards is provided with in described substrate centre position; Form the accommodation space that holds coil between described iron core and the described side plate.

In highly effective transformer of the present utility model, the distance between the outer rim of described iron core and the inwall of described side plate is equidistant.

In highly effective transformer of the present utility model, the cross sectional shape of described iron core is for chamfering quadrangle; Corresponding, the cross sectional shape of described substrate is the chamfer quadrangle similar to described iron core.

In highly effective transformer of the present utility model, four limits of described substrate stretch out and form the extension that is provided with for described side plate.

In highly effective transformer of the present utility model, described side plate comprises four side plates that are separately positioned on the described extension.

In highly effective transformer of the present utility model, the outer surface of the substrate of described shell is provided with groove; Described securing member is the clasp that buckle is located at the respective grooves of described two shells.

In highly effective transformer of the present utility model, the surface of described groove is provided with the hole line that increases frictional force.

In highly effective transformer of the present utility model, described coil winding is on coil brace.

Enforcement the utlity model has following beneficial effect: by using shell separately, and iron core is set on shell, and coil is contained between iron core and the side plate, greatly reduce the size of whole transformer, and can improve the conversion efficiency of whole transformer.

Embodiment

To shown in Figure 5, is an embodiment of highly effective transformer of the present utility model as Fig. 1, comprises two shells 10 with same structure, with the securing member 20 of two shells, 10 lockings and be arranged on coil (figure does not show) between the shell 10 etc.This transformer can be applied to carry out the conversion of voltage on the power supply circuit board, and stablized, suitable out-put supply.

Because two shells 10 have identical structure, therefore describe with one of them below.This shell 10 comprises substrate 11, the side plate 12 that upwards is provided with at the edge of substrate 11 and the iron core 13 that upwards is provided with in substrate 11 centre positions.Form accommodation space 14 between this iron core 13 and the side plate 12, be used to hold coil.

As shown in the figure, the cross sectional shape of the iron core 13 of present embodiment is for chamfering quadrangle, and is corresponding, and the cross sectional shape of substrate 11 is the chamfer quadrangle similar to iron core 13; And the distance between the inwall of the outer rim of iron core 13 and side plate 12 is equidistant the setting, makes coil to be contained in uniformly in the accommodation space 14, thereby improves the efficient of whole transformer.

In the present embodiment, four limits of this substrate 11 formation extension that stretches out, and side plate 12 is arranged on the edge of extension, and side plate 12 is four separated side plates 12, thus can increase the volume of spatial accommodation, raise the efficiency.

The outer surface of the substrate 11 of this shell 10 is provided with groove 15, corresponding, this securing member 20 is a clasp.This clasp is snapped in the respective grooves 15 of two shells 10, thereby with two shell 10 fastenings.Understandable, this securing member 20 can also adopt other form, corresponding button hole and clasp for example is set on shell 10 or uses trip bolt, bolt etc.

In the present embodiment,, also be provided with the hole line, thereby increase frictional force, make better two shells 10 of fastening of clasp on the surface of groove 15 in order to make the clasp hook establish more reliably.

In when assembling, earlier with the coil winding on coil brace; Then, coil brace is set in the periphery of the iron core 13 of one of them shell 10, covers another shell 10 then, re-use in the groove 15 that the clasp hook is located at two shell 10 correspondences, thereby, be assembled into a complete transformer two shell 10 fastenings.

Above embodiment has only expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model; Therefore, all equivalents and modifications of being done with the utility model claim scope all should belong to the covering scope of the utility model claim.
