Description

Compact electrical transformers

Technical field

The utility model is related to field transformer technologies, refer in particular to a kind of compact electrical transformers.

Background technology

Power transformer is to generate the magnetic magnetic line of force by coil, and then magnetic force line cutting coil generates electricity in coil Stream, by the equipment for changing full line voltage and changing of coil turn, generally boosting becomes and decompression becomes two kinds.Common electric power becomes That there are structures is not compact enough for depressor, and appearance and size is big, and the defect of poor sealing constrains the development of industry.

Utility model content

In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of small electrical Power transformer, not only compact-sized, appearance and size is small, and has moistureproof and waterproof performance, to overcome the prior art not Foot.

To achieve the above object, the utility model is using following technical solution：

A kind of compact electrical transformers, including

There is reel, the left and right ends of the reel to be provided with the left retaining wall of protrusion for one insulation framework, the insulation framework It is winding area between the left retaining wall and right retaining wall with right retaining wall, the reel surface of the winding area, which is equipped with, is used for opposing connection The tongue and groove of line positioning；

Winding and pin, the winding are wound in the reel by a plurality of conducting wire；The pin and insulation bone Frame is integrally formed, and is distributed on the downside of the left and right ends of insulation framework, and the conducting wire of the winding two ends is corresponding with pin respectively to connect, Formation electrically conducts；

One magnetic core, the magnetic core hole that the inside of the reel has left and right through, the magnetic core are arranged in the magnetic core hole It is interior；

Both ends sealing portion carries out sealing after winding is assembled to insulation framework with magnetic core in the left and right ends of insulation framework Processing forms both ends sealing portion after solidification.

As a preferred embodiment, the winding has four groups, and the conducting wire of each winding is insulated from each other, and the pin of correspondence has two Row, often arranging pin has 5PIN.

As a preferred embodiment, the pin is in-line structure.

As a preferred embodiment, the tongue and groove is waveform or zigzag.

As a preferred embodiment, both ends sealing portion extends to lower end from the upper end of insulation framework and seals pin Upper end.

The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology Scheme since the reel surface of insulation framework is equipped with tongue and groove, on the one hand can position coiling, make it is found that first Winding process is more light, on the other hand, when insulation framework uses ceramic heat emission material, moreover it is possible to increase heat dissipation area, favorably In heat dissipation.Second, it is compact-sized after assembling since magnetic core is in the magnetic core hole being built in inside insulation framework, farthest Assembly space is saved, transformer is made more to minimize, meets the size requirement of compact electrical transformers.Third, transformer it is each After the completion of assembling fittings, both ends sealing processing is finally carried out, forms both ends sealing portion after solidification, thus by each component assembly process The gap of middle generation is sealed, and ensures its moistureproof and waterproof performance.

More clearly to illustrate the structure feature and effect of the utility model, come below in conjunction with the accompanying drawings with specific embodiment pair The utility model is described in detail.

Specific implementation mode

It please refers to shown in Fig. 1 and Fig. 2, that show the concrete structures of the preferred embodiment of the utility model, are a kind of Compact electrical transformers, structure include insulation framework 10, winding 20, pin 30, magnetic core 40 and both ends sealing portion 50.

Wherein, the insulation framework 10 is molded using plastic-injection, certainly, ceramic skeleton etc. also can be used.It is described There is insulation framework 10 reel 11, the left and right ends of the reel 11 to be provided with the left retaining wall 12 of protrusion and right retaining wall 13, the left side It is winding area between retaining wall 12 and right retaining wall 13, after conducting wire is wound in the winding area, left retaining wall 12 and right retaining wall 13 can Outside is skidded off to prevent conducting wire from loosening.In addition, 11 surface of reel of the winding area is equipped with recessed for being positioned to coiling Tongue 14.In the present embodiment, the tongue and groove 14 is waveform or zigzag, can also be the slot of other formation certainly, herein not It illustrates one by one.By the design of tongue and groove 14, on the one hand coiling can be positioned, keep winding process more light, it is another Aspect, when insulation framework 10 is using ceramic heat emission material, moreover it is possible to increase heat dissipation area, be conducive to radiate.

The winding 20 is wound in the reel 11 by a plurality of conducting wire.For example, the quantity of winding 20 can be Four groups but it is not limited to four groups.The conducting wire of each winding 20 is insulated from each other.The pin 30 is integrally formed with insulation framework 10, this implementation In example, pin 30 has two rows, is distributed on the downside of the left and right ends of insulation framework 10, and often arranging pin 30 has 5PIN but be not limited to 5PIN.The conducting wire of the two ends of each winding 20 is corresponding with pin 30 respectively to connect, and formation electrically conducts.In this way, by the pin 30 be in-line structure, after forming entirety, pin 30 is plugged on corresponding circuit board, can realize transformer function.

The magnetic core hole 15 that the inside of the reel 11 has left and right through, the magnetic core 40 are arranged in the magnetic core hole 15 It is interior.Since magnetic core 40 generates magnetic field, after energization, transformation function is realized under the action of primary coil and secondary coil.This product Due to assembling magnetic core 40 in the inside of insulation framework 10, space is made full use of, transformer is made more to minimize, meets small electrical The size requirement of power transformer.

The sealing function of transformer may be implemented in both ends sealing portion 50.When four groups of windings 20 and magnetic core 40 are assembled to absolutely After edge skeleton 10, sealing processing is carried out in the left and right ends of insulation framework 10, forms both ends sealing portion 50 after solidification, thus will be each The gap generated during component assembly is sealed, and ensures its moistureproof and waterproof performance.In the present embodiment, both ends sealing portion 50 extend to lower end from the upper end of insulation framework 10 and seal the upper end of pin 30, namely it is meant that conducting wire and pin 30 Connection jaws are also sealed, and can improve electrical security.

The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change Change and modify, is still within the scope of the technical solutions of the present invention.
