Description
Technical field
The utility model is related to transformer, particularly relates to a kind of pair of skeleton enclosed reinforced insulation type Switching Power Supply
Transformer.
Background technology
The utility model is that a kind of outer encompassing reinforced insulation type is used for the high frequency transformer of Switching Power Supply, and Switching Power Supply becomes
Depressor will reach the insulation request of safety standard standard due to safety standard requirements, primary and magnetic core to secondary coil, tradition
Skeleton be divided into common skeleton and extended type skeleton；Common skeleton does not reach the safety standard requirements of primary and secondary, and extended type bone
Frame has reached safety standard distance, but adds the length and volume of transformer, is unfavorable for the increasingly compact miniaturization of Switching Power Supply
And modularized design.
The content of the invention
For deficiency of the prior art, the technical problems to be solved in the utility model is the provision of a kind of pair of skeleton bag
Enclose formula reinforced insulation type switching mode power supply transformer.
In order to solve the above technical problems, the utility model is realized by following scheme：A kind of pair of skeleton enclosed is strengthened
Insulated switching power supply transformer, the transformer includes magnetic core, bobbin skeleton, winding and support arm；
The magnetic core includes upper magnetic core and lower magnetic core, and the upper magnetic core is consistent with lower core structure, U-shaped at its all to be U-shaped
Inner bottom surface, is provided with stem；
It is cylinder in the middle part of the bobbin skeleton, the cylinder is provided with lower through-hole, and upper magnetic core and lower magnetic core are respectively sleeved in this
The top and bottom of through hole, the side of bobbin skeleton bottom surface one is provided with primary stitch；
Support arm is a square box body, and its upper opening is provided with secondary stitch, the secondary stitch in its side
The segment distance of support arm bottom surface one is exposed to, and the offside of secondary stitch is provided with row's formula pin jack；
The assembly of the bobbin skeleton and magnetic core integrally inserts support arm, primary stitch is inserted in row's formula pin of support arm
In jack, and primary stitch is set to be exposed to the segment distance of support arm bottom surface one.
Further, the magnetic core, bobbin skeleton, winding and support arm assembling after in addition to top surrounding by support arm
Colloid is surrounded.
Relative to prior art, the beneficial effects of the utility model are：The utility model is reduced and become using double skeleton modes
Strengthen and be dielectrically separated from while depressor volume, it mainly includes：Magnetic core, bobbin skeleton, winding and support arm, this is new with passing
The system transformer main distinction is that this is new by the way of bobbin skeleton and outer encompassing holder combination, and inner frame is basic
Coiling and primary stitch skeleton, support arm are bottom surrounding enclosed and secondary windings stitch, and primary stitch and secondary stitch are not
On a skeleton, respectively on bobbin and support arm, bobbin unites two into one with support arm after assembling, support arm from
Bottom and surrounding surround magnetic core, winding and bobbin skeleton, and surrounding is surrounded by support arm colloid in addition to top after assembling, real
Show the physical isolation of surrounding, strengthen insulating properties.
