Description
Technical field
The utility model relates to a kind of transformer, and espespecially a kind of leakage inductance is adjusted transformer.
Background technology
Transformer is electronic component commonly used in present electronic equipment, mainly by a coil holder, a group unshakable in one's determination, a primary coil and a level coil, formed, wherein said primary coil and described secondary coil are wound on described coil holder, and described group unshakable in one's determination wears described coil holder and described primary coil and the induction of described secondary coil generation electromagnetic coupled, reaches the purpose of voltage transitions.
The leakage inductance of transformer (leakage inductance) does not reach absolutely for the coupling between described primary coil and described secondary coil, the magnetic line of force that described primary coil produces the not inductance that produces leakage field of the part by secondary coil is leakage inductance, namely the part magnetic flux missed in the process that is coupled of the described primary coil of described transformer and described secondary coil.In the design of transformer, all wish to increase the coupling efficiency of primary and secondary coil in the past, reduced leakage inductance to reduce the energy loss of voltage transitions.Yet, in the power system of the electronic equipment of a new generation such as LCD TV,, take the transformer of tool leakage inductance type as main flow, can reduce the noise in electric current.Present transformer such as TaiWan, China I2911831 patent in order to increase leakage inductance, it is a kind of transformer device structure, comprises at least a main coiling, a level coiling, a Winder bracket module and a group unshakable in one's determination.Group unshakable in one's determination is arranged in Winder bracket module, and Winder bracket module comprises one first winding part and one second winding part, and described the first winding part is used for being wound around described main coiling, and described the second winding part is used for being wound around described secondary rolling thread.Wherein, each described first winding part and described the second winding part have one first side plate, and described the first winding part and described the second winding part are each other with described the first side plate separately or be connected, in order to do described main coiling is separated mutually with described secondary rolling thread, to increase leakage inductance and electrical safety distance.Yet the leakage inductance value that the method can be adjusted is certain value, and can't immediately adjust according to different demands.
In view of this, in order to adjust leakage inductance value according to the situation demand more easily, improvement is arranged then as TaiWan, China I280720 patent, it is a kind of frequency-fixed power supplier, be applied to have on a suitching type circuit of primary side and secondary side, described frequency-fixed power supplier includes: one first iron core, one second iron core, one first coil holder and one second coil holder, and described the first iron core and one second iron core are corresponding setting, it has respectively one first convex body and one second convex body; Described First Line chord position is on described the first convex body, and described the first coil holder is wound with one first group of pins of first group of coil and electric connection primary side; Described the second coil holder is positioned on described the second convex body, one second group of pins that described the second coil holder is wound with second group of coil and is electrically connected secondary side; Wherein, but described the first coil holder more includes a running-on of described the second coil holder of fit, make described the first coil holder and described the second coil holder can utilize described cover interruption-forming one sliding extension, in described the first convex body and described the second enterprising line displacement of convex body motion, and adjust inductance between described primary side and secondary side.Yet, also can't fix to each other between described the first coil holder and described the second coil holder, the position of meeting of described the first coil holder and described the second coil holder easily changes, to such an extent as to the gap between described two coil can't be fixed, can't assemble according to default gap exactly when assembling, and inductance value is arranged and preset different problems, produce.moreover, the above-mentioned structure that sees through between support body sliding extension change coil holder length and then change primary side and secondary side, although can adjust inductance value, but in general the iron core group specification of same coil holder is fixed, length of its group unshakable in one's determination is to coordinate coil holder length and determine, if and as its iron core of above-mentioned length-adjustable coil holder, organize length, fix, when adjusting coil holder length, fixedly the distance between two iron cores of the described group unshakable in one's determination of specification namely can change, related change inductance value size, therefore this flexible coil holder must could be adjusted to leakage inductance value the value of anticipation through accurate calculating in the use, very bother.
