Description

Transformer

[technical field]

The present invention relates to a kind of transformer, particularly relate to a kind of transformer that can be used for the backlight liquid crystal display module.

[background technology]

As shown in Figure 1, the transformer that generally can be used for the backlight liquid crystal display module during fabrication, normally adopt a mould 101, an and foot rest 102 that sets in advance in this mould 101, this mould 101 cooperates this foot rest 102 just can produce several drum stands 10 by the mode of ejection formation, the described drum stand 10 of design is to extend along a first direction Y at present, and after the moulding outside this first direction Y is pushed out this mould 101, the zone, stage casing of described drum stand 10 provides a primary coil (figure does not show) and reels, before this primary coil, the back segment zone is to provide two secondary wire (figure does not show) circle to reel respectively, 11 of several pins that this foot rest 102 is constituted are to extend along a second direction X perpendicular to this first direction Y, described pin 11 be evenly distributed in described drum stand 10 before, in, the back segment zone, because this primary coil can be connected by direct and nearest described pin 11 with described secondary coil, therefore follow-up coiling coil, the processing procedure of fixed coil will be easier.

Yet design aspect at this mould 101, because described drum stand 10 lays respectively at left and right two districts of this mould 101, and the described pin 11 in left and right two districts must have a spacing d, therefore when the producer wants along most drum stands of measuring 10 of this second direction X making, the configuration of described drum stand 10 can be subjected to the influence of this spacing d and can't closely arrange, cause the volume of this mould 101 bigger, and the shortcoming of production restriction.

[summary of the invention]

The objective of the invention is to be to provide a kind of when mold design, the configuration of all drum stands can both tightr arrangement, and then effectively promotes the transformer of output.

The invention provides a kind of transformer, comprise a drum stand unit, one core unit, an and coil unit, this drum stand unit comprises a support body along length direction extension, one passes the hole unshakable in one's determination of this support body along this length direction, and several are from the outward extending pin of this support body, this core unit comprises an inner iron core and an outer iron core, this inner iron core is to be arranged in this iron core hole, and have two and be provided with on the contrary and extend connection end outside this iron core hole, should outer iron core have two segmentum laterales that are connected to described connection end respectively, and one extend and connect the linkage section of described segmentum laterale along this length direction, this coil unit comprises one first coil, one second coil, and a tertiary coil, this transformer is characterised in that:

The support body of this drum stand unit has one first winding region, a spacer region of arranging in regular turn along this length direction, and one second winding region, described pin is to extend along this length direction from the opposite end of this support body respectively, and this iron core hole is to pass this first and second winding region and this spacer region;

The outer iron core of this core unit also has one between described segmentum laterale and pass this spacer region and the interlude of this inner iron core of butt, and this interlude is to be connected with this linkage section; And

First and second coil of this coil unit is to be wound in this first and second winding region and to be connected with adjacent described pin, and this tertiary coil is to be wound in this outer interlude periphery unshakable in one's determination.

Beneficial effect of the present invention is: because the support body of this drum stand unit and described pin all are to extend along this length direction, therefore in the time will making several support bodys, the die cavity that constitutes described support body just can be arranged perpendicular to the transverse direction of this length direction along one, and when arranging, this transverse direction do not need to reserve the space of settling described pin, so the configuration closeness of described support body is higher, do not need significantly to increase the volume of this mould yet, just can reach the use effect of abundant lifting output.
