Abstract

The invention discloses a transformer, belonging to the technical field of a transformer. The transformer comprises a winding rack, an iron core and a fastening element, wherein a wire is wound on the winding rack and provided with a through hole passing through the winding rack, the iron core passes through the through hole to form a magnetic loop, the fastening element comprises a first member and a second member which are separated, and the first member and the second member are engaged and encircle the winding rack and the iron core so as to fix the winding rack and the iron core. With the transformer disclosed by the invention, the gap between the iron core at the bottom and the fastening element at the bottom can be prevented, and the transformer is easy and simple to assemble.

Description

A kind of transformer

Technical field

The present invention relates to a kind of transformer, belong to transformer technology field.

Background technology

Be illustrated in figure 5 a kind of transformer in prior art, comprise top core 10, bottom iron core 11, drum stand 12 and pin apart from positioned fastener 13.Above-mentioned transformer 1 assembling operation process is: coiling on drum stand 12; By drum stand 12 and top core 10 and bottom iron core 11 is vertical assembles; The top core 10 assembled, drum stand 12 and bottom iron core 11 orthogonal sets are installed to pin on positioned fastener 13; The wire be wrapped on drum stand 12 is connected to pin on positioned fastener 13.

There is following shortcoming in above-mentioned transformer: one, transformer is in assembling process, needs to assemble drum stand 12, top core 10, bottom iron core 11 and pin in the vertical direction apart from positioned fastener 13, operational difficulty; Two, when assembly puts in place, there is gap apart from positioned fastener 13 in the bottom of bottom iron core 11 and pin, causes size bad bad with noise test.

Summary of the invention

For above-mentioned deficiency, the invention provides a kind of transformer, the gap bottom bottom iron core and securing member can be avoided, and assembling is easily simple.

The present invention adopts technical scheme as follows:

A kind of transformer, comprise drum stand, iron core and securing member, described drum stand is wound with wire and there is the through hole that runs through described drum stand, described iron core forms magnetic loop through described through hole, described securing member comprises the first component and the second component of separate type, described first component docks with second component and crowds around described drum stand and iron core, fixing described drum stand and iron core.

The bottom that described securing member contacts with iron core is provided with opening, and described opening is all or part of exposes described iron core, and the area of described opening portion is greater than 1/2nd of securing member bottom area.

The bottom that described securing member contacts with iron core is engraved structure, exposes described iron core with part.

Described securing member has electrical lead, and the wire on described drum stand is connected with described electrical lead.

Compared with prior art, beneficial effect of the present invention is:

1. the securing member of stationary transformer drum stand and iron core adopts the structure of separate type, securing member directly and drum stand assembly, avoid drum stand and iron core group to install into rear vertical situation of assemble with securing member and occurs, thus it is simply easy that transformer is assembled, and transformer size can not be caused bad.

2. opening is set bottom securing member, avoid bottom securing member with the air vibration in the gap of mandrel bottom, produce noise.

Embodiment

Embodiment:

Refer to shown in Fig. 1-4, a kind of transformer transformer comprises drum stand 20, iron core 29 and securing member 30.Described drum stand 20 is wound around wire, to form armature winding and secondary winding (not shown).Described conductive line surfaces has insulating barrier, and described drum stand 20 has the through hole 21 that runs through described drum stand 20, and described through hole 21 allows iron core 29 to pass.Iron core 29 forms a closed magnetic loop through the through hole 21 of drum stand.The shape of described iron core 29 is E type.Iron core 29 comprises iron core 23 bottom E type top core 22 and E type, described top core 22 and the through hole 21 of bottom iron core 23 by drum stand.Inner at through hole 21, top core 22 is connected with bottom iron core 23, to form closed magnetic loop.Described securing member 30 comprises the first component 24 and the second component 25 of separate type, and described first component 24 docks with second component 25 and crowds around described drum stand 20 and iron core 29, fixing described drum stand 20 and iron core 29.

Described first component 24 docks rear employing buckle structure to be fixed both with second component 25.Respectively there is a stuck point 27 at the two ends of the first component 24, respectively have a draw-in groove 26 at the two ends of second component 25.When the first component 24 docks with second component 25, draw-in groove 26 and the stuck point 27 of described correspondence fasten, and form fixing structure for buckle.First component 24 of described securing member 30 docks and direct and drum stand 20 assembly from the both sides of drum stand 20 with second component 25, avoid drum stand 20 and iron core 29 to combine rear vertically to occur with situation that is securing member 30 assembly like this, thus make the assembling of transformer 2 simply easy.

The bottom that described securing member 30 contacts with iron core 29 is provided with opening (not shown), and described opening is all or part of exposes described iron core 29, and the area of described outs open is greater than 1/2nd of securing member 30 bottom area.

The bottom of described first component 24 and second component 25 is engraved structure, and the bottom that described securing member 30 is contacted with iron core 29 is engraved structure, exposes described iron core with part.Described engraved structure can support iron core and the air bottom securing member 30 and between bottom iron core 23 also can be made to circulate with extraneous, can not cause air vibration, thus avoid producing noise when transformer 2 uses.

Described securing member 30 is provided with pin 28, and the wire that described drum stand 20 is wound around is connected on described pin 28, and described pin 28 is connected with extraneous device.First component 24 is provided with multiple pin 28, and described pin 28 distance is each other fixed, thus described securing member 30 can realize pin 28 pin apart from location.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
