Description

A kind of novel transformer

Technical field

The utility model belongs to field transformer, relates more specifically to a kind of radiator structure of transformer.

Background technology

Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is primary coil, secondary Level coil and iron core（Magnetic core）, belong to intensive equipment.Transformer can operationally produce heat, and the heat is mainly derived from two Individual aspect：First, iron loss, is exactly heat caused by the vortex missing in transformer core；Second, load current flow through transformer around Heat caused by group, this caloric value and electric current it is square directly proportional.These heats have to dissipate in time, otherwise can damage change Depressor.Generally add aluminium alloy heat radiator in inside transformer in the prior art or increase aluminium alloy radiating on magnetic core of transformer Device increases fan for cooling in the supply.This structure setting can cause volume of transformer increase or transformer in production process Middle increase material cost and cost of labor make power supply increase volume and cost.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a kind of novel transformer, without increase Heat can be discharged in time on the premise of volume of transformer and manual assembly expense.

The utility model technique effect to be reached is realized by following scheme：A kind of novel transformer, including magnetic core, Armature winding and secondary windings, armature winding and secondary windings are sheathed on magnetic core, the transformer also include with secondary around The secondary pins of group connection, the secondary pins are made of copper foil.

Further, the copper foil is the red copper that Nickel Plating Treatment is crossed.

Further, the quantity of the secondary pins is 3.

Further, the height of the height of the secondary pins and Transformer Winding is mutually fair or can not be higher by transformer magnetic At the top of core.

Further, the armature winding is the winding with twisted wire coiling.

Further, the armature winding is twisted coiling with a diameter of 0.3-0.6mm insulated copper wire and formed.

Further, the secondary windings is the winding with copper foil coiling.

Further, insulating part is provided between the armature winding and secondary windings, the thickness of the insulating part is 0.05- 1.0mm。

Further, the transformer is inductor.

The utility model has advantages below：

Primary winding in the utility model uses twisted wire coiling, skeleton can be saved, without the product of skeleton Size than there is the small of skeleton.The secondary windings can be combined directly one to be formed with more copper sheet coilings with armature winding Rise, reduce the time of secondary rolling thread, ease of assembly, there was only armature winding and copper foil in the confined space of magnetic core, can fully make With limited space, armature winding and secondary windings contact with the external world, are more beneficial for radiating.By using secondary made of copper foil Pin declines transformer temperature as the radiator of transformer, ensures normal work, and the structure transformer is not required to increase volume With manual assembly expense.

Embodiment

Clear, complete explanation is carried out to the utility model with reference to the accompanying drawings and examples.

Transformer of the prior art is as shown in figure 1, the transformer includes winding 100, magnetic core 200, pin 300 and dissipated Hot device 400, the radiator 400 are aluminium alloy heat radiator, and bonding is arranged on the top of magnetic core 200.Because the top of magnetic core 200 is bonded Certain thickness radiator 400, causes volume of transformer to increase, adds material cost and cost of labor.

The utility model proposes a kind of novel transformer, refer to shown in Fig. 2-Fig. 4, in the utility model preferred embodiment In, the transformer includes magnetic core 1, armature winding 2, secondary windings 3 and secondary pins 4, and the magnetic core 1 includes two of splicing E type flat board magnetic cores, the armature winding 2 and secondary windings 3 are sheathed on magnetic core 1, and the magnetic core is assembled into " day " type.It is described Magnetic core 2 is used for magnetic conduction so that the energy of the armature winding 2 can be delivered on secondary windings 3.The armature winding 2 is change Depressor connects the side of power supply, and secondary windings 3 is then the side of transformer connection load.

The transformer also includes the secondary pins 4 being connected with secondary windings 3, and the secondary pins 4 are made of copper foil, institute The number for stating secondary pins 4 is 3, depending on the size of the size foundation transformer of the secondary pins 4, the secondary pins The height of height and Transformer Winding mutually maintains an equal level or can not be higher by the top of magnetic core of transformer, the height and transformation of preferred secondary pin The height ratio of device is 1:0.8.Effectively the heat of transformer can be passed to outside by inside using the secondary pins 4 made of copper foil Portion, makes the Wen Duxiajiang of transformer in itself, ensure transformer can in suitable environment normal work.Wherein described copper foil is plating The treated red copper of nickel, is integrally formed, convenient welding and heat conduction.

Armature winding 2 described in this structure is the winding with twisted wire coiling, skeleton can be saved, without the transformer of skeleton Size than there is the small of skeleton.Further, the armature winding 2 with a diameter of 0.3-0.6mm insulated copper wire it is twisted around System forms, and anti-short circuit capability is strong, and current-carrying capacity is big.

The method that secondary windings 3 described in this structure is molded with copper foil, it can directly combine, subtract with armature winding 2 Few coiling time of secondary windings 3, ease of assembly, there was only armature winding 2 and copper foil in the confined space of magnetic core 1, can fully make With limited space.Armature winding 2 and secondary windings 3 contact with the external world, are more beneficial for radiating.

Insulating part is additionally provided between the armature winding 2 and magnetic core 1（Not shown in figure）, the number of plies of the insulating part is 2 Layer or 3 layers, it be 0.05-1.0mm to reach thickness, can effectively reduce loss and raising insulating reliability.

The structure of inductor is similar to transformer, but an only winding, and pin uses skill made of copper foil in transformer Art scheme is equally applicable in inductor.

It is last it should be noted that above example is only illustrating the technical scheme of the embodiment of the present invention rather than it is entered Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, one of ordinary skill in the art It should be understood that can still be modified to the technical scheme of the embodiment of the present invention or equivalent substitution, and these modifications or wait The scope of amended technical scheme disengaging technical scheme of the embodiment of the present invention can not also be made with replacement.
