The utility model is to solve technical problem mentioned above in the background art, provides a kind of transformer.Use metal Piece is around in the both ends lateral column of magnetic core as secondary coil, forms knockdown transformer, and structure is simple, improves transformer performance, drop Low-power consumption, good heat dissipation effect.

The utility model provides a kind of transformer, and the transformer includes magnetic core, and the magnetic core includes the first magnetic core, the Two magnetic cores and the connection core being connected between the first magnetic core and the second magnetic core；It surrounds and is equipped on the outside of first magnetic core and the second magnetic core Coil, coil outer, which surrounds, is equipped with sheet metal.

Further, the transformer further includes set on the sheath body between the first magnetic core and the second magnetic core and coil, coil It is surrounded on sheath body.

Further, the transformer further includes set on the insulating film between coil and sheet metal, and insulating film wraps up coil In on sheath body.

Further, the sheet metal has multilayer, is equipped with diaphragm between sheet metal.

Further, the sheet metal both ends are equipped with pole piece.

Further, the transformer further includes the pedestal for putting connection core.

Further, described pedestal one end is equipped with fixed plate, and the fixed plate is equipped with multiple for placing consolidating for pole piece Determine slot.

Further, the sheet metal is copper sheet.

Further, the connection core has multiple, multiple connection cores respectively with first magnetic core and the second magnetic core two End connection.

The beneficial effects of the utility model are: the utility model make that secondary coil is around in magnetic core respectively using sheet metal the Outside one magnetic core and the second magnetic core, sheet metal superposition is simple, can preferably control the circle number of secondary coil；First magnetic core and the second magnetic Core is equivalent to two small transformers, and the first magnetic core and the second magnetic core are combined and form knockdown transformer, structure is simple, function Rate is high, low in energy consumption, good heat dissipation.

Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model Limitation.

The utility model is described in further detail below by specific embodiment combination attached drawing.

As shown in Fig. 1 ~ 5, the utility model provides a kind of transformer, and the transformer includes magnetic core 1, the magnetic core 1 Including the first magnetic core 12, the second magnetic core 13 and the connection core 11 being connected between the first magnetic core 12 and the second magnetic core 13；First magnetic Around coil (figure does not mark) is equipped with, coil outer, which surrounds, is equipped with sheet metal 2 for core 12 and 13 outside of the second magnetic core.This is practical new Type sheet metal 2 makees secondary coil around outside the first magnetic core 12 and the second magnetic core 13, and structure is simple, and power is fast；First magnetic Core 12 and the second magnetic core 13 are equivalent to two small transformers, form combined transformer, and performance is stronger, and power is high.

In a specific embodiment, the transformer further include set on the first magnetic core 12 and the second magnetic core 13 and coil it Between sheath body 3, coil encircling is on sheath body 3；The transformer further includes set on the insulating film between coil and sheet metal 2, absolutely Velum wraps up coil on sheath body 3.In the utility model, magnetic core 1 is entangled with sheath body 3, coil encircling is on sheath body 3.

In one alternate embodiment, the sheet metal 2 has multilayer, is equipped with diaphragm between sheet metal 2.In the utility model, Use two sheet metals 2 as two layers of secondary coil.Sheet metal 2 is superimposed simply, and the number of plies of sheet metal can select as needed.

In a specific embodiment, 2 both ends of sheet metal are equipped with pole piece 21；The transformer further includes for putting Connect the pedestal 4 of core 11；Described 4 one end of pedestal is equipped with fixed plate 5, and the fixed plate 5 is equipped with multiple for placing pole piece 21 Fixing groove 51.In the utility model, the putting groove of magnetic core 1 is put in setting on pedestal 4, and one end of pedestal 4 sets fixed plate 5, Gu Determine the pole piece 21 of the fixed sheet metal 2 of slot 51.

In one alternate embodiment, the sheet metal 2 is copper sheet.

In one alternate embodiment, the connection core 11 has multiple, multiple connection cores 11 respectively with first magnetic core 12 and second magnetic core 13 both ends connection.In the present embodiment, connects there are two cores 11, be respectively arranged on the first magnetic core 12 and the second magnetic After the both ends of core 13, first magnetic core 12 and the second magnetic core 13 pass through sheath body 3, then will connection core 11 and the first magnetic core 12 and the Two magnetic cores 13 connection closure, forms knockdown transformer.
