Description

A kind of transformer and Switching Power Supply for facilitating Automated winding

Technical field

The utility model is related to the present invention relates to switch power technology field, more particularly to a kind of switching mode power supply transformer and Switching Power Supply with transformer.

Background technology

Switching mode power supply transformer is generally by skeleton, magnetic core, armature winding, secondary windings, chip power supply winding, shield winding Composition.

In the prior art, armature winding typically have along around with sandwich winding, traditional sandwich winding be it is primary around Group is divided into two parts, and most the inside and the outermost of skeleton are wound on respectively, and secondary windings is wound on intermediate layer, as shown in Figure 1.Tradition Sandwich winding on the one hand it is complicated；On the other hand due to the line bag out-of-flatness after complete secondary windings, increase around primary around The difficulty of group, so as to cause Machine automated coiling also than relatively difficult to achieve, typically using semi-automatic winding method, in turn result in life Produce cost higher, lose competitive advantage.

Utility model content

In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide that a kind of winding structure is simple, it is automatic to be adapted to Change the transformer of coiling and the Switching Power Supply with the transformer.

The technical scheme that the utility model is used is：

Be wound with successively on a kind of transformer for facilitating Automated winding, including skeleton, the skeleton the first armature winding, Second armature winding, chip power supply winding, shield winding and secondary windings.

It is preferred that, the secondary windings is triple insulated wire winding.

It is preferred that, first armature winding and the second armature winding are enamel-cover line winding.

It is preferred that, the shield winding is enamel-covered wire shield winding.

It is preferred that, between second armature winding and chip power supply winding, between chip power supply winding and shield winding, Insulating tape is provided between shield winding and secondary windings.

It is preferred that, the insulating tape is that wheat draws adhesive tape or copper foil tape.

A kind of Switching Power Supply, it includes above-mentioned transformer.

The beneficial effects of the utility model are：

The present invention by by two parts armature winding of switching mode power supply transformer first around the side of, other windings successively coiling Formula so that transformer device structure is simple, each winding wire bag is smooth, so that facilitate coil to automate coiling, and then reduction production cost, The conversion efficiency of transformer is improved simultaneously.

The utility model can be widely applied to various switching mode power supply transformers and the Switching Power Supply with transformer.

Brief description of the drawings

Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：

Fig. 1 is the winding schematic diagram of switching mode power supply transformer in the prior art；

Fig. 2 is the equivalent circuit diagram of switching mode power supply transformer in the prior art；

Fig. 3 is the Transformer Winding schematic diagram of an embodiment of the present invention；

Fig. 4 is the equivalent circuit diagram of the transformer of an embodiment of the present invention.

Embodiment

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase Mutually combination.

As shown in Figure 3 and Figure 4, is wound with successively on a kind of transformer for facilitating Automated winding, including skeleton, skeleton One armature winding N1, the second armature winding N2, chip power supply winding N3, shield winding N4 and secondary windings N5.By that will switch Two parts armature winding of power transformer is first around the mode of, other windings successively coiling so that transformer device structure is simple, it is each around Group line bag is smooth, so as to facilitate coil to automate coiling, and then production cost is reduced, while improving the conversion efficiency of transformer.

In Fig. 3 and Fig. 4, the first armature winding N1 and the second armature winding N2 are wound on skeleton, two leading-out terminals 1 and 3 that This connection, forms the input of armature winding；Chip power supply winding N3 is wound on the second armature winding N2, and leading-out terminal is 4 and 5； Shield winding N4 is wound on chip power supply winding N3, and leading-out terminal is 5 and 6；Secondary windings N5 is wound on shield winding N4, leading-out terminal For 7 and 8.

In the present embodiment, secondary windings N5 is triple insulated wire winding.Secondary windings N5 uses three-layer insulated line winding.The One armature winding N1 and the second armature winding N2 is enamel-cover line winding.Shield winding N4 is enamel-covered wire shield winding N4.Using Enamel-cover line winding can meet the insulating properties requirement of transformer.

In the present embodiment, between the second armature winding N2 and chip power supply winding N3, chip power supply winding N3 with shielding around Insulating tape is provided between group N4, between shield winding N4 and secondary windings N5.Wherein, insulating tape be wheat draw adhesive tape or Copper foil tape.Insulating tape can play a part of insulation or signal shielding isolation.

Present invention also offers a kind of Switching Power Supply, it includes above-mentioned transformer.

Above is preferable implementation of the present utility model is illustrated, but the invention is not limited to implement Example, those skilled in the art can also be made on the premise of without prejudice to the utility model spirit a variety of equivalent variations or Replace, these equivalent deformations or replacement are all contained in the application claim limited range.
