Description
Technical field
The present invention relates to a kind of transformer, particularly relate to during fabrication a kind ofly, allow the process leakage-adjustable inductance transformer that the iron core of a group unshakable in one's determination can relatively move.
Background technology
As shown in Figure 1, be general transformer 100 structures of using at a backlight module, this transformer 100 comprises a core unit 11, one is incorporated into the drum stand unit 12 of this core unit 11, one is arranged at the primary coil 13 of this drum stand unit 12, an and secondary coil 14 that is arranged at this drum stand unit 12, each backlight module all comprises a plurality of transformers 100 and lights many tubes, in order to make the brightness unanimity of every tubes, each transformer 100 should have identical inductance value as far as possible with the secondary coil 14 that fluorescent tube connects, and it is average just to reach electric current whereby, the application target of lighting tube brightness unanimity.
Yet, this core unit 11 tends to produce maximum error during actual the manufacturing, reason is that this core unit 11 is to belong to no air-gap magnetic core, sintering has many variable influences again when making, so after 100 manufacturings of a transformer are finished, can find that through test the inductance value error range is up to 40%, leakage inductance value error range is up to 10%, the error range 1% that this and shipment require is far apart, if see through follow-up grinding again, modes such as processing are improved defective products, also can consume a large amount of following process time, need not to such an extent as to there are many products all directly to be abandoned in screening process, produce extremely low yield, and make whole cost significantly increase.
In addition, because general core unit 11 all is to be combined by plural assembly 111 unshakable in one's determination, assembly unshakable in one's determination 111 as shown in Figure 1 is respectively I shape and O shape, when adopting the EE shape structure of mutual butt, adjust if position unshakable in one's determination moved, the position of primary coil produced air gap in the middle of this can make, cause a large amount of leakage magnetic flux, so can significantly influence electric power output, so be not suitable for carrying out adjustment work with the air gap mode, and take a broad view of 11 designs of at present general core unit, and all can't keep this primary flux to stablize under the constant state, can also reach the effect of secondary flux being adjusted change.
Summary of the invention
When the objective of the invention is to be to provide a kind of manufacturing, can be by adjusting the structural design of leakage inductance value, make the leakage inductance error range of each transformer to reach the shipment standard, and then can significantly improve the process leakage-adjustable inductance transformer of process rate by adjustment.
This process leakage-adjustable inductance transformer comprises a drum stand unit, a primary coil, a level coil, and a core unit.This primary and secondary coil all is to be arranged at this drum stand unit.This core unit is the flux path that is mounted on this drum stand unit and forms this primary coil of connection and this secondary coil.
The invention is characterized in: this core unit comprises one first iron core, one is connected in second iron core of this first iron core, one is formed between this first iron core and this second iron core and the primary flux district of close this primary coil, reaching one is formed between this first iron core and this second iron core and the secondary magnetic flux district of close this secondary coil, this drum stand unit this core unit around be reserved with allow this first, the space that two iron cores relatively move, the useful flux area in the useful flux area in this primary flux district and this secondary magnetic flux district is unequal, and allow this first, two iron cores relatively move down and change this secondary magnetic flux district and keep this primary flux district.
Beneficial effect of the present invention is: if find that this secondary inductance value and shipment standard have error during manufacturing, then can change the magnetic leakage flux of this secondary coil by the design that this first and second iron core relatively moves, and then just can make this secondary inductance value can reach the shipment standard, and reach the application target that significantly improves process rate.
