Embodiment

Referring to figs. 1 through Fig. 3, preferred embodiment of the present utility model provides a kind of transformer, and it includes a bobbin winder base 100, a pair iron core 200 and at least one insulating cover 300.

Bobbin winder base 100 is preferably the insulating base frame that plastics are made, its one first baffle plate 120 and second baffle 130 including a shaft sleeve 110 and be respectively formed at shaft sleeve 110 two ends.First baffle plate 120 and second baffle 130 extend along the radial direction of shaft sleeve 110 respectively, and the first baffle plate 120 and second baffle 130 are parallel to each other, interval configures.Shaft sleeve 110 is wound with at least one pair of coil 400 (coils), the winding scope of coil 400 is defined between the first baffle plate 120 and second baffle 130.First baffle plate 120 is provided with electric connection wherein a coil 400 a pair first pins 121 and be electrically connected a pair second pins 122 of another coil 400, and this structure can copy expansion configuration, the logarithm of the first pin 121 and the second pin 122 also can be different again.In the present embodiment, the first baffle plate 120 is preferably provided with three to the first pin 121 and three to the second pin 122, and preferably corresponding configuration three pairs of coils 400 are wound on shaft sleeve 110.Again, the adjacent wherein side being laid in the first baffle plate 120 of the first pin 121, the second pin 122 is adjacent be laid in the first baffle plate 120 opposite side and also with the first pin 121 configured separate.

Iron core 200 is configured in the both sides of the shaft sleeve 110 of bobbin winder base 100 and makes end-coil 400 between this is to iron core 200.Each iron core 200 includes a cover plate 210 respectively, and this is oppositely disposed the cover plate 210 of iron core 200.In each iron core 200, the edge of cover plate 210 extends pair of sidewalls 230 along its forward, and in the present embodiment, this oppose side wall 230 is relative configuration and corresponding with on another iron core 200 respectively sidewall 230 of each sidewall 230 continues and connects.This is covered in outside the first baffle plate 120 and second baffle 130 to cover plate 210 respectively, and therefore the first baffle plate 120 and second baffle 130 are between this is to cover plate 210.A stem stem 220 is extended along the forward of cover plate 210 respectively in the center of the cover plate 210 of each iron core 200, and stem stem 220 is arranged within shaft sleeve 110 and makes coil 400 between stem stem 220 and sidewall 230.The continuity of this stem stem 220 to iron core 200 connects, and the junction of stem stem 220 is positioned at shaft sleeve 110.

In this example, transformer is preferably configured with a pair insulating cover 300, but the utility model is not as limit.Insulating cover 300 is between the first pin 121 and the second pin 122.Each insulating cover 300 comprises with pair of end portions 310 respectively and is connected to this to the sidepiece 320 between end 310, and the sidepiece 320 of each insulating cover 300 is covered in the sidewall 230 that is wherein connected for a pair respectively and its each end 310 is covered in the part of each cover plate 210 respectively.Bonding fixing with a binding agent 301 respectively between iron core 200 sidewall 230 of insulating cover 300 and its covering.Moreover, the both side edges of the sidepiece 320 of each insulating cover 300 is formed with respectively a location structure 123; First baffle plate 120 is then formed can the location structure 302 of corresponding clamping, can locate whereby when assembling insulating cover 300.In the present embodiment, each pair of location structure 123,302 be respectively the form of flange and corresponding chute but the utility model not as limit.

Matched transformer of the present utility model is placed on the circuit board 10 of a power supply changeover device (not shown), and transformer can be fixedly welded on circuit board 10 by its first pin 121 and the second pin 122 and be electrically connected circuit board 10.It can by circuit board 10 in the first pin 121 input current to each coil 400 of being connected with the first pin 121, in each coil 400 of connection second pin 122, produce induced current by electromagnetic induction and export adjusted induced current by the second pin 122, the input of electric current and outbound course also can exchange, and the utility model is not limited thereto.

Each sidewall 230 of the iron core 200 in transformer cover by insulating cover 300, therefore, it is possible to intercept the first pin 121 and the second pin 122 and the insulation distance increased between the first pin 121 and the second pin 122 by insulating cover 300.Moreover each insulating cover 300 covers the cover plate 210 of each iron core 200 respectively, compared to only covering sidewall 230, it can make iron core 200 and circuit board 10 form longer insulation distance between other electron component 20.Therefore meeting under the insulation distance prerequisite that relevant safety regulations formulates, on transformer and circuit board 10, other electron component 20 can more close-packed arrays, so as to reducing the overall volume of power supply changeover device.

The foregoing is only preferred embodiment of the present utility model, be not used to limit right of the present utility model, other uses the equivalence of patent spirit of the present utility model to change, and all should belong to the scope of the claims of the present utility model.
