Abstract

The utility model relates to an improved transformer structure which is mainly composed of an iron core unit and a coil unit, wherein the iron core unit is composed of two opposite iron cores which are mutually overlapped, and one surface of each iron core is concaved into a groove which can be clamped for positioning with the coil unit, and the bottom surface of one side edge of the iron core is provided with a coil leading out groove, and the coil leading out surface of the position for positioning the coil leading out groove is in a flat or convex mold; the coil leading out surface is clamped with the clamping block at the top edge of a coil former of the coil unit, and finally, the coil unit can be coated and clamped in the two iron cores to form into a transformer via the two iron cores. The coil can be completely coated by the flat or convex design of the coil leading out surface, and thus, the effects of high efficient shielding property and magnetic leakage prevention can be obtained. A coil conducting wire of the coil unit can be flat extended outside a transformer via the coil leading out groove.

Description

Transformer device structure

Technical field

The utility model relates to a kind of transformer device structure, it mainly is the design that goes out wire casing by iron core, can make the lead of coil can be smooth-going extend transformer outside and unlikely recessed lose to hinder influence whole efficiency, and also can prevent that by outlet face evagination and straight design coil from producing leakage field picture now, makes this transformer have advantages such as high efficiency, low-loss thus.

Background technology

Transformer 1 is made up of 11 and one coil groups 12 unshakable in one's determination mostly at present, sees also shown in Figure 1.Yet the iron core 11 of general transformer 1 is designed to ask the lead 122 in the coil groups 12 directly to pull out in transformer 1 outside by extending in coil 121 inside, be that unshakable in one's determination 11 upper limb outlet face is offered a breach 111 mostly, lead 122 directly can be extended by the setting of this breach 111 and pull out in transformer 1 outside.Also can cause transformer 1 to produce leakage field picture now though this mode is easy, if can not solve leakage field picture now, then this transformer 1 can't meet all users' demand.

Thereby all transformer manufacturers avoid the transformer produced to produce leakage field picture now, how improve leakage field from the aspects such as shielding of the manufacture process of lead winding or lead and now look like; But these methods still have shortcomings such as the too high and quality of whole manufacturing cost is wayward.Even, many manufacturers are more arranged for reducing the leakage field generation of picture now, change and adopt the higher toroidal transformer of cost, but the transformer of this pattern still exists that cost is too high, frequency can not be too high etc. problem.Therefore based on above-mentioned every shortcoming, under many-sided consideration such as cost, efficient and leakage field degree, the mode that traditional transformer solves leakage field has the necessity that is improved in fact.

Summary of the invention

General transformer is made for the low manufacturing cost of begging to surrender reaches to convenient; usually can on iron core, offer a breach for the winding wire outlet; though outlet breach unshakable in one's determination can reduce the difficulty of transformer assembling; but cause the generation of picture now of transformer leakage field also simultaneously, so the leakage field of transformer will be one of emphasis reference of decision transformer overall efficiency and quality as how to solve now.

Technological means provided by the utility model, be on the iron core of transformer, to offer one to specialize in winding wire and extend the wire casing that goes out pull out in the transformer outside, and the outlet face design that will go out the wire casing position forms an evagination or straight moulding, by this outlet face and the design that goes out wire casing the transformer coil lead can directly be extended swimmingly pulls out in the transformer outside, more can make the leakage field situation of this transformer reduce to minimum.

Via enforcement of the present utility model, can reach following advantage than prior art:

One,, can make the leakage field situation of transformer integral body reduce to minimum by enforcement of the present utility model.

Two, by enforcement of the present utility model, can make the lead of coil inside directly extend to the coil outside swimmingly, do not have the recessed situation of losing wound of lead and take place.

Three,, except that can reducing the generation of picture now of the whole leakage field of transformer, also can simplify the assembling of transformer integral body and reduce whole cost by enforcement of the present utility model.

Embodiment

Following spy enumerates an embodiment, to describe structure of the present utility model, effect and feature in detail:

Seeing also Fig. 2 and shown in Figure 3, is stereogram of the present utility model and three-dimensional exploded view, the structure of the transformer 2 of a kind of improvement of the present utility model shown in its figure.It mainly is made up of iron core group 21, coil groups 22, group 21 wherein unshakable in one's determination is made up of opposed unshakable in one's determination 211 mutual overlap joints about in the of two, and one side that should iron core 211 to be recessed to form be one can engage the groove 2111 of location with coil groups 22, and at least one lateral margin bottom surface that should iron core 211 offers out wire casing 2112 (going out the opposed place of two-phase that wire casing also can be arranged at lateral margin unshakable in one's determination bottom surface simultaneously) in addition, and the lead 2221 of coil 222 inside can go out wire casing 2112 smooth-going coil 222 and transformer 2 outsides of extending by this.So, 2221 in this lead does not have the recessed situation generation of losing wound.This outlet face 2113 that goes out wire casing 2112 positions is the moulding of a straight or evagination, and this outlet face 2113 is that apical margin fixture block 2211 with the bobbin 221 of coil groups 22 fastens, and coil groups 22 can be coated by aforementioned two unshakable in one's determination 211 at last and be equipped in wherein and form a transformer 2.Can coat coil 222 fully by 2113 designs straight or evagination of outlet face, use and reach efficiently shielding properties and can prevent that leakage field is now as generation.

Seeing also Fig. 4 A, Fig. 4 B and shown in Figure 5, is the stereogram of cutaway view, broken section enlarged drawing and another embodiment of the utility model one embodiment, the structure of the transformer 2 of the improvement of the utility model shown in the figure.Group 21 wherein unshakable in one's determination is by two being inverted 211 unshakable in one's determination and forming up and down, and should iron core group 21 be that coil groups 22 clampings are coated on wherein.In addition, can smooth-going extension pull out in transformer 2 outsides under the not recessed situation of losing wound for the lead 2221 that makes coil 222 inside, offer one and go out wire casing 2112 on unshakable in one's determination 211, this goes out, and wire casing 2112 is main keeps away the position by establishing for leads 2221.Therefore go out the setting of wire casing 2112 by this, then can make things convenient for and smooth-going lead 2221 is extended, and make the lead 2221 unlikely recessed wounds of losing.In addition, the outlet face 2113 of 211 lateral margins unshakable in one's determination is except that can be straight shape-designing, also can be the moulding of evagination, can offer the better shield effectiveness of coil 222, use and reduce the generation of picture now of transformer 2 whole leakage fields by 2113 shape-designings straight or evagination of outlet face.
