Abstract

The utility model discloses a structure improvement for a transformer. The coils of the structure improvement for a transformer are wound on a hollow pipe-shaped winding frame, the winding frame is divided into three sections through two separation sheets, and the coils are respectively wound on the three different sections; the coil of each section is coupled in an electromagnetic mode, a couple of iron cores are threaded through both sides of the winding frame and connected to form a return circuit, and two dc voltage convertors can be simultaneously driven; accordingly, the self-volume of the transformer is decreased, and the purposes of saving the space, improving the efficiency, and reducing the cost can be achieved.

Description

The structural improvement of transformer

Technical field

The utility model relates to the structural improvement of transformer, refers to a kind of transformer device structure that can drive two alterating and direct current pressure converters simultaneously especially.

Background technology

Press; the fluorescent tube that all necessary use of LCD at present is high-effect and external form is light and handy is as back light; and cathode fluorescent tube (Cold Cathode Fluorescent Lamp; CCFL) become and be the fluorescent tube of normal use in the LCD now; about 12 cun to 15 cun LCD that do not wait adopt 1 to 2 tubes mostly at present; it is screen each 1 tubes up and down; because self character and technical problem; in the display left and right sides and central authorities; the phenomenon that brightness disproportionation usually can obviously occur; two increase fluorescent tube numbers then are one of solutions; along with the size of LCD is increasing, need many fluorescent tubes just can reach certain display effect especially simultaneously.

Though the more tubes of quantity can have preferable display effect, still have many problems of demanding urgently overcoming.For example, one tubes needs an alterating and direct current pressure converter (Inverter) to drive, and an electric pressure converter also needs a transformer to cooperate, therefore the fluorescent tube number is many more, the number of electric pressure converter and transformer also increases thereupon, relative, the volume of LCD also becomes greatly, and product cost also increases much.

The utility model content

The structural improvement of the utility model transformer, its main purpose are to drive two alterating and direct current pressure converters simultaneously, and the volume of transformer own is reduced, and more can reach to save the space, raise the efficiency and reduce cost.

For reaching above-mentioned purpose, the utility model coil is to be set around on the drum stand of a thread blank pipe shape structure, and utilize the two compartment sheet that drum stand is divided into three sections, three sections are respectively a pair of secondary rolling thread district and the middle elementary winding region of both sides, be respectively secondary coil and primary coil and be set around each section, make secondary coil can with the primary coil electromagnetic coupled, a pair of iron core is arranged in the both sides of drum stand, engage and form a loop.

Embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

The drum stand 20 that the structural improvement of the utility model transformer, its transformer include an a pair of E sections core 10 and a thread blank pipe shape structure constitutes; Wherein, the structure of this drum stand 20 as shown in Figures 1 and 2, perforated hole 21 is laid in its both sides, and utilize two compartment sheet 22 that drum stand 20 is divided into three sections, three sections are respectively a pair of secondary rolling thread district 23 and the middle elementary winding region 24 of both sides, be separated with several winding slots 26 in 25 minutes with separator on each winding region, each winding slot 26 of each a pair of secondary rolling thread district 23 and elementary winding region 24 is wound with secondary coil 30 and primary coil 40 respectively, and this shim 22 is a L type, both sides are equiped with two branch connecting pins 221, in order to connect the end of a thread of primary coil, in drum stand 20 both sides and be formed with the support portion 27 of pair of L type, its 27 both sides, support portion are equiped with pin 271, in order to the end of a thread of connecting secondary coil 30 as electric energy output end, hand over straight electric pressure converter to drive, and then light cathode fluorescent tube.

Moreover, please the while three shine shown in Figure 3, this E sections core 10 has one first contact site 11, one second contact site 12 and the 3rd contact site 13, lay respectively at the set place of iron core 10E type end, this perforated hole 21 that iron core 10 is seen through drum stand 20 is worn to penetrate and is made that in drum stand 20 this can mutual involutory connection to each contact site of iron core 10, and forms an electromagnetic circuit.

In addition, as Fig. 4 and Figure 5 shows that the another kind of package assembly of transformer, after a pair of secondary coil 30 and primary coil 40 being set around on each winding slot 26 of secondary rolling thread district 23 and elementary winding region 24 respectively, be placed in earlier in the insulation cell body 50, its cell body 50 both sides are provided with perforated hole 51 and can be involutory with the perforated hole 21 of drum stand, second contact site 12 with iron core 10 wears in regular turn in each

perforated hole

51,21 again, make that this can mutual involutory connection to each contact site of iron core 10, and form an electromagnetic circuit.

What deserves to be mentioned is, the utility model can drive two alterating and direct current pressure converters simultaneously, its volume is commonly used closing of transformer less than two, bigger and a fairly large number of problem of volume of transformer is commonly used in solution, and use two groups of secondary coils, can share output current, increase the stability of this transformer, have high efficiency, volume is little and low cost and other advantages.

The volume of transformer own is reduced, more can reach and save the space and raise the efficiency and reduce cost.

As mentioned above, the utility model provides a kind of transformer device structure that can drive two alterating and direct current pressure converters simultaneously, so, offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be one of this creation preferred embodiment, be not to limit to this creation with this, be with, approximate, identical with the structure of this creation, device, feature etc. such as, all should belong within the creation purpose and claim of this creation.
