Description
Technical field
The utility model relates to transformer technology field, especially a kind of transformer of charger for mobile phone.
Background technology
At present, the electronic product used in life get more and more, accordingly, these electronic products all need to be equipped with corresponding charger, with guarantee electronic product have electricity for, so the use of charger is very frequently.Transformer is as the core component in charger, and the performance of its quality on charger has vital impact; Because in prior art, the volume of transformer of charger is large, insulation distance is little, cause the volume of charger to reduce further, transformer insulated performance and interference free performance poor; Meanwhile, existing transformer easily produces phenomenon of arc discharge, reduces the security performance of transformer.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide the transformer of the charger for mobile phone that a kind of structure is simple, volume is little, insulation effect is good, fail safe is high, antijamming capability is strong.
To achieve these goals, the utility model adopts following technical scheme:
A kind of transformer of charger for mobile phone, it comprises skeleton, the magnetic core be arranged on skeleton, be wound in armature winding on skeleton and magnetic core and secondary winding, the adjustable winding that described armature winding comprises fixing winding and is made up of the first coil and the second coil, one end of described second coil is connected with one end of the first coil, the unsettled setting of the other end.
Preferably, the bottom of described skeleton is provided with primary side pin seat and primary side pin seat, and the width of described primary side pin seat is greater than the width of primary side pin seat.
Preferably, described primary side pin seat is provided with barricade.
Preferably, described primary side pin seat offers two secondary pins holes, and the spacing between described secondary pins hole is 9.0 ± 0.3mm; Described primary side pin seat offers five primary pins holes, and the spacing between described primary pins hole is 2.75 ± 0.2mm.
Preferably, described skeleton length, width and be highly all less than or equal to 15mm.
Owing to have employed such scheme, the utility model meets the demand of the change in voltage of charger for mobile phone by the fixing winding that arranges and adjustable winding; Meanwhile, the width due to the primary side pin seat on skeleton is less than the width of primary side pin seat, adds the insulation distance between transformer secondary and magnetic core, and then improves the insulation property of transformer; And utilize the barricade be arranged on primary side pin seat to suppress the generation of phenomenon of arc discharge, thus improve the security performance of transformer; Its structure is simple, volume is little, has very strong practicality.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the transformer of the charger for mobile phone of the present embodiment, it comprises length, width and is highly all less than or equal to the skeleton 1 of 15mm, the magnetic core be arranged on skeleton 1, is wound in armature winding on skeleton 1 and magnetic core and secondary winding N4 (label of drawing the end of a thread is 6 and 7); Wherein, the adjustable winding that armature winding comprises the fixing winding N1 label of (draw the end of a thread be 1 and 2) and is made up of the second coil N2 (label of drawing the end of a thread is 4 and 5) and the first coil N3, one end of the second coil N2 is connected with one end of the first coil N3 (be namely connected with No. 4 the end of a thread, the other end (being labeled as NC) unsettled setting; With this, met the demand of the change in voltage of charger for mobile phone by the fixing and adjustable winding arranged.
Simultaneously, primary side pin seat 2 and primary side pin seat 3 is provided with in the bottom of skeleton 1, the width of primary side pin seat 3 is greater than the width of primary side pin seat 3, increases the insulation distance between transformer secondary and magnetic core with this, and then improves the insulation property of transformer.And on primary side pin seat 3, be provided with barricade 4, with the generation utilizing barricade to suppress phenomenon of arc discharge.
Spacing primary side pin seat 3 offered between secondary pins hole 5, two 5, two, secondary pins holes side by side controls in 9.0 ± 0.3mm; Primary side pin seat 2 offers five primary pins holes 6 side by side, and the spacing between each primary pins hole 6 controls in 2.75 ± 0.2mm; Utilize pin bores to be drawn by the end of a thread of each winding or coil with this, simultaneously by the fixing fabric structure of whole transformer in rational scope.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
