Description
Technical field
The utility model relates to electronic component technology field, relates in particular to transformer.
Background technology
As everyone knows, as shown in Figure 1, existing transformer comprises skeleton 10 ' and coil, and its coil adopts the stranded cylinder core 20 of multiply enamelled wire ' be wound on skeleton 10 ' upper to form conventionally.But due to the general stranded core 20 of cylinder ' easily cause winding displacement sparse, thereby make the tankful rate of coil winding lower, cause the power output of transformer lower, therefore need improvement badly.
Foregoing is only understood the technical solution of the utility model for auxiliary, does not represent and admits that foregoing is prior art.
Utility model content
Main purpose of the present utility model is to provide a kind of transformer, is intended to improve the tankful rate of coil winding, promotes the power output of transformer.
To achieve these goals, the transformer that the utility model provides, comprises skeleton and is wound in the coil on skeleton; Described coil comprises by the core of pressing square one-tenth after some wire strandings, the setting that is square of the cross section of described core.
Preferably, described wire is enamelled wire.
Preferably, described skeleton comprises two limiting sections that are oppositely arranged and for connecting the winding section of two limiting sections; One limiting section is provided with the through hole for passing for magnetic core, and described through hole extends to another limiting section through described winding section, and runs through another limiting section.
Preferably, described winding section is provided with louvre, and described louvre and described through hole are interconnected.
Preferably, described winding section is cylinder setting.
Preferably, described coil also comprise be heated after tool sticking from haircuts, be describedly wrapped in described core outside from haircuts.
The utility model is pressed after some wire strandings the core of square one-tenth to be wound on and on skeleton, is formed coil by adopting, thereby has improved the tankful rate of coil winding, has promoted the power output of transformer.In addition, because square core is tightr than circular core twisted wire, make winding space obtain optimum utilization, winding operation is more smooth and easy, effectively improving production efficiency.
Brief description of the drawings
Fig. 1 is the cross-sectional view of traditional transformer;
Fig. 2 is the cross-sectional view of the utility model transformer one embodiment.
Realization, functional characteristics and the advantage of the utility model object, in connection with embodiment, are described further with reference to accompanying drawing.
Embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of transformer, and with reference to Fig. 2, in one embodiment, this transformer comprises skeleton 10 and is wound in the coil on skeleton 10; Described coil comprises by the core 20 of pressing square one-tenth after some wire strandings, the setting that is square of the cross section of described core 20.
In the present embodiment, above-mentioned coil comprises primary coil and secondary coil, is wound on and is formed on skeleton 10 by core 20.Particularly, above-mentioned core 20 by some wire strandings after, by specific tool, pressure side forms, this core 20 is after overvoltage side processes, the setting that is square of the cross section of core 20 vertical its length directions, it should be noted that four drift angles of this cross section can be fillet setting.Press after some wire strandings the core 20 of square one-tenth to be wound on skeleton 10 by adopting and form coil, thereby can make the tankful rate of coil winding reach percent 96.
In the present embodiment, press after some wire strandings the core 20 of square one-tenth to be wound on skeleton 10 by adopting and form coil, thereby improved the tankful rate of coil winding, promoted the power output of transformer.In addition, because square core 20 is tightr than circular core 20 twisted wires, make winding space obtain optimum utilization, winding operation is more smooth and easy, effectively improving production efficiency.
The material that it should be noted that above-mentioned wire can be carried out according to actual needs, and in the present embodiment, above-mentioned wire is preferably enamelled wire.
Particularly, above-mentioned skeleton 10 comprises two limiting sections that are oppositely arranged and for connecting the winding section of two limiting sections; One limiting section is provided with the through hole 111 for passing for magnetic core (not shown), and described through hole 111 extends to another limiting section through described winding section, and runs through another limiting section.
In the present embodiment, between above-mentioned two limiting sections and winding section, form a winding slot, above-mentioned core 20 is wound on described winding section, and is positioned at winding slot.Above-mentioned winding section quite with a connecting axle, above-mentioned through hole 111 connects two limiting sections and winding section 112 vertically successively.
Further, above-mentioned winding section is provided with louvre 121, and described louvre 121 is interconnected with described through hole 111.
In the present embodiment, above-mentioned louvre 121 radially connects above-mentioned winding section, and be communicated with above-mentioned through hole 111, due to louvre 121 being set on winding section, thereby be conducive to the heat radiation of the coil (being positioned at the coil of inner side) near winding section, ensure the stability of transformer, extended the useful life of transformer simultaneously.
Be understandable that, the shape of above-mentioned winding section can arrange according to actual needs, and in the present embodiment, above-mentioned winding section is preferably and is cylinder setting.
Further, described coil also comprise be heated after tool sticking from haircuts, be describedly wrapped in described core 20 outsides from haircuts.
In the present embodiment, above-mentionedly made by fiber material from haircuts 20, particularly, should from haircuts 20 comprise be heated after the sticking fiber material of tool.After above-mentioned core 20 is wound on skeleton 10, can, by heating, make between the core 20 of adjacent turn by the moulding that is adhesively fixed from haircuts.Therefore the ability of shaping while effectively having prevented because of coiling, makes product on assembling operation, increase certain difficulty, causes in the time of winding efficiency not high, waste of human resource and cost increases.
These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
