Abstract

Disclosed is a transformer with a magnetic conductor with a horizontal through out groove. The utility model provides a transformer with simple structure, convenient assemble, avoidance of poor conduction and stable connection. The utility model comprises a magnetic conductor and a conducting part. The magnetic conductor is composed of a plurality of iron core parts being stacked together, and is provided with two parallel through grooves; the two ends of the conducting parts pass through the two through out grooves of the magnetic conductor respectively and then are bended outward to form bending parts exposed out of the through out grooves of the magnetic conductor.

Description

Has the parallel transformer that runs through the slot permeance body of formation

Technical field

The utility model belongs to transformer, particularly a kind of have form the parallel transformer that runs through the slot permeance body.

Background technology

As everyone knows, when electric power is carried because the resistance on the landline, electric current by the time can cause the loss of part electric energy, and the electric current that passes through is big more, the energy that is lost on the conveying circuit is just many more.Therefore, in order to reduce energy loss, on electric power is carried, need reduce the impedance of transport path as far as possible.

So, as shown in Figure 1 and Figure 2, mainly be that the conducting piece that utilizes iron core to reach to coil produces the magnetic line of force in general transformer, to increase the efficient of its power conversion.Right traditional iron core lies in its inside and is provided with for what be that wearing around mouth that the coil of enamelled wire passes, coil then pass iron core repeatedly and is wound in the inside and outside portion of iron core around mouth.

The transformer of this kind structure, it not only assembles comparatively difficult complicated, and because of need cause bigger impedance through long path, the bad problem of conduction takes place easily; In addition, it is when assembling, and when being equipped on it on printed circuit board (PCB), it only only depends on by terminal that stretches out in the iron core and printed circuit board (PCB) welding, and its bonding area is little, and the welding impedance is bigger, causes the power of loss bigger.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, simple and convenient assembly, avoids conducting bad phenomenon, connects the firm parallel transformer that runs through the slot permeance body of formation that has.

The utility model comprises magnetic conductor and conducting piece; The magnetic conductance system is piled up mutually by the plural pieces iron core piece and is formed; Have the two mutual parallel grooves that run through on the magnetic conductor; The conducting piece two ends place magnetic conductor two respectively and run through the outwards bending of the outer back of groove, expose to magnetic conductor with formation and run through the outer kink of groove.

Wherein:

Iron core piece system is combined relatively by two E shape sheets, and forms the two mutual parallel perforation that formation magnetic conductor two runs through groove.

Several pieces iron core pieces pile up mutually and form the magnetic conductor periphery coated insulation sheet with suitable height.

Conducting piece passes the two mutually parallel grooves that run through of magnetic conductor respectively with its two ends, and extend run through the outer back of groove outwards bending expose to the kink that magnetic conductor runs through groove with formation, make conducting piece be Ω shape, and extend up in kink and to collude the hook part that is fixed in outside the magnetic conductor and has suitable length.

Conducting piece is the conduction lamellar body of being made by Copper Foil or other equivalent metal materials that is Jiong shape.

The conducting piece two sides are coated with insulating barrier.

Because the utility model comprises magnetic conductor and conducting piece; The magnetic conductance system is piled up mutually by the plural pieces iron core piece and is formed; Have the two mutual parallel grooves that run through on the magnetic conductor; The conducting piece two ends place magnetic conductor two respectively and run through the outwards bending of the outer back of groove, expose to magnetic conductor with formation and run through the outer kink of groove.When being incorporated into printed circuit board (PCB) on surface adhering technology (SMT) or welding manner the utility model, can be by the kink and the direct conducting of the contact on the printed circuit board (PCB) of conducting piece, and make between itself and contact to have certain contact area, can form firm electrically conducting; And be detained tin cream by the hook part that conducting piece has a suitable length, to increase fixing effect.And as exposing the welding position, can be made for the industry personnel with kink when carrying out weld job, simultaneously can visual pad whether firm, be convenient to process the carrying out of operation; Remove can to exempt in the past and pass iron core repeatedly with enamelled wire and wear around mouth being wound in the complicated machining clearance of the inside and outside portion of iron core, and can increase the coupling area of conducting piece and magnetic conductor, thus the raising energy conversion efficiency.Not only simple in structure, simple and convenient assembly, and avoid conducting bad phenomenon, connection firmly, thus reach the purpose of this utility model.

Embodiment

As shown in Figure 3, Figure 4, the utility model comprises plural pieces iron core piece 1, conducting piece 2 and insulating trip 5.

Iron core piece 1 is to be combined relatively by two E shape sheets 10, and forms two mutual parallel perforation 11,12.Plural pieces iron core piece 1 piles up mutually and forms the magnetic conductor 3 with suitable height, and two mutual

parallel perforation

11,12 of each iron core piece 1 form the two mutual

parallel grooves

31,32 that run through on magnetic conductor 3.

Conducting piece 2 is the conduction lamellar body of being made by Copper Foil or other equivalent metal materials that is Jiong shape.As shown in Figure 6, conducting piece 2 two sides are coated with insulating barrier 4.

As Fig. 3, shown in Figure 5, during assembling, conducting piece 2 passes the two mutually

parallel grooves

31,32 that run through of magnetic conductor 3 respectively with its two

ends

21,22, and extend and run through the outwards bending of the outer back of

groove

31,32, expose to magnetic conductor 3 with formation and run through

groove

31,32 kink 23,24 outward, make conducting piece 2 be Ω shape, and extend up in kink 23,24 and to collude the hook part 25,26 that is fixed in outside the magnetic conductor 3 and has suitable length; Insulating trip 5 is coated on magnetic conductor 3 peripheries; Conducting piece 2 is done suitably to isolate with magnetic conductor 3 by the insulating barrier 4 that coats thereon.

As shown in Figure 5, when the utility model being incorporated on the printed circuit board (PCB) 6, can be by the kink 23,24 of conducting piece 2 and the direct conducting of contact on the printed circuit board (PCB) 6, and make between itself and contact and have certain contact area, can form firm electrically conducting.

When the utility model is incorporated on the printed circuit board (PCB) 6, with surface adhering technology (SMT) or welding manner combination in addition.The utility model is detained tin cream by the hook part 25,26 that conducting piece 2 has suitable length, to increase fixing effect.And as exposing the welding position, can be made for the industry personnel with kink 23,24 when carrying out weld job, simultaneously can visual pad whether firm, be convenient to process the carrying out of operation.

Substitute in addition the practice of coil, remove to exempt in the past and pass iron core repeatedly with enamelled wire and wear around mouth being wound in the complicated machining clearance of the inside and outside portion of iron core, and can increase the coupling area of conducting piece 2 and magnetic conductor 3, thereby improve energy conversion efficiency with copper foil.
