Description

The transformer of tool fin

The utility model relates to a kind of transformer, and it is preferable to relate in particular to a kind of radiating effect, is difficult for breaking down, and also has the transformer of the tool fin that is easy to assemble.

The main effect of transformer is through implementing the lifting of alternating voltage or a kind of electronic component of impedance conversion after the effect of coil, so that transformer is subjected to being engaged in the manufacturing personage of electronics industry is widely-used with alternating current.

Employed and discuss (as shown in Figure 4) with present tradition, comprising having:

One slightly is the support 60 of I shape, be wound with the coil 61 of some circles in support 60 lateral attitudes, be coated and fixed with adhesive tape 62 in coil 61 outsides, be respectively arranged with in the upper and lower position of support 60 and be the relative magnetic core of E shape 70, outside at magnetic core 70 is twined coating adhesive tape again, one fin 80 that is ∏ shape is set on coil 61, still, said structure combination back and have following shortcoming when using and remain to be improved:

1. radiating effect is relatively poor, transformer is broken down: when transformer at adstante febre, thermal source is mainly at coil 61 and magnetic core 70 places, and the radiating effect of fin 80 only be by coil 61 heat conduction to fin 80, but when the area of dissipation of fin 80 is big inadequately, the not good shortcoming of radiating effect is then arranged, and Yin Wendu is too high and transformer is burnt quite easily.

2. be not easy to assembling: when carrying out assembling operation, two magnetic cores that combine relatively 70 need be binded in seam crossing mutually by viscose, then need be twine a few backs and coat and bind with adhesive tape in magnetic core 70 outsides, assemble comparatively time-consuming, take a lot of work.

Main purpose of the present utility model is to provide a kind of transformer of improved tool fin, and its radiating effect is preferable, is difficult for producing fault, and has the advantage that is easy to assemble.

The purpose of this utility model is achieved in that

A kind of transformer of tool fin, comprise: a support, be coated with a few coils outside winding of support, coat with adhesive tape in outermost layer coil outside, horizontal place at support establishes magnetic core, be characterized in: on described magnetic core, with the relative position place one fin is set respectively respectively, each fin forms the two side that intersects vertically in its underpart, each sidewall with respect to magnetic core on, the upper/lower positions place has been bent to form buckling piece respectively inwardly, each buckling piece can be held in respectively magnetic core on, upper/lower positions, the place forms a flange respectively in the sidewall corner of each fin, is provided with one in the adjacent flange outer sides of each fin and two fin are fastened is the clasp of one.

In the transformer of above-mentioned tool fin, wherein, each is bent to form the arc portion on the outside that clasp can be held on each flange inwardly with respect to the outside of flange on described each clasp, and this arc portion can be held on clasp on the outside of each flange really.

The utility model makes it compared with prior art owing to adopted above-mentioned technical scheme, has following advantage and good effect at least:

1. has preferable radiating effect, be difficult for breaking down: the utility model is owing to be provided with the bigger fin of area respectively at the relative position place of magnetic core, and can each fin fastening be one by one group of clasp, when transformer in adstante febre, heat can conduct on each sheet fin via the effect of coil, magnetic core, because of the area of each sheet fin is bigger, thus preferable radiating effect can be had, available to prevent that transformer from producing fault because of overheated burning.

2. have the advantage that is easy to assemble: the utility model since between each fin and magnetic core when assembling mutually, the buckling piece button that forms respectively in inboard upper and lower position by each fin is held in the place, upper and lower position of magnetic core 20, be fastened on the adjacent ribs 35 outside places of each fin 30 between each fin 30 mutually with clasp 40, so can finish the assembly program of transformer by mode quite easily, so have the advantage that is easy to assemble.

Embodiment by following transformer to the utility model tool fin can further understand and illustrate the purpose of this utility model, specific structural features and advantage in conjunction with the description of its accompanying drawing.Wherein, accompanying drawing is:

Fig. 1 is the three-dimensional appearance structural representation according to the transformer of the tool fin that the utility model proposes;

Fig. 2 is the three-dimensional decomposition texture schematic diagram according to the transformer of the tool fin that the utility model proposes;

Fig. 3 be according to the transformer of the tool fin that the utility model proposes in conjunction with the sectional structure schematic diagram;

Fig. 4 is the three-dimensional decomposition texture schematic diagram of prior art transformer.

As shown in Fig. 1 to Fig. 3, the utility model is a kind of transformer with fin, comprising having:

One is the support 10 of I shape, is coated with a few coils 11 support 10 outside vertically windings, is coated and fixed with adhesive tape 12 in outermost coil 11 outsides.

Be provided with magnetic core 20 in support 10 lateral attitudes, on magnetic core 20, respectively establish a fin 30 with the relative position place respectively, each fin 30 is to form the two

side

31,32 that intersects vertically in its underpart, locate inwards to be bent to form respectively buckling piece 33,34 at each

sidewall

31,32 with respect to the upper and lower position of magnetic core 20, each buckling piece 33,34 can be respectively by being held in the place, upper and lower position of magnetic core 20, each fin 30 is for to have bigger area of dissipation, and can have preferable radiating effect.

Sidewall

31,32 edges at each fin 30 form a flange 35 respectively, between each fin 30 adjacent flange 35 outside is from top to bottom to buckle on one group of flange 35 by a clasp 40, be formed with arc portion 50 at clasp 40 with respect to the outside of flange 35 towards inner bending, can be with arc portion 50 for the outside that is clamped in each flange 35.

In sum, the topmost characteristics of the transformer of the utility model tool fin are to be: because the area of dissipation of each fin 30 is for bigger, thus can have preferable radiating effect, and be difficult for making transformer to break down because of overheated; Simultaneously, when in assembling, only need easily the buckling piece 33,34 of each fin 30 to be snapped in respectively the place, upper and lower position of each magnetic core 20, the clasp 40 that has an arc portion 50 with one group of inboard again 35 of the flanges of one group of fin 30 is fastened and is formed then, and has the advantage that is easy to assemble assembling.
