Abstract
The utility model provides a kind of soft stitch high frequency transformer, including skeleton, magnetic core and coil, and skeleton is provided with wire casing, and the coil is arranged in wire casing；It further include soft stitch, soft stitch is threaded through the edge of skeleton, and one end is in the wire casing, and the other end is in the outside of skeleton；The one end of the soft stitch in wire casing connects the coil.Technical solution provided by the utility model, stitch is threaded through to the edge of skeleton, the terminals of coil are connected to one end that stitch is located in wire casing, the outside that the terminals of coil are located to skeleton is not needed, to solve the problems, such as to cause high frequency transformer reliability lower since coil is wound around outside skeleton in the prior art；And since stitch is soft stitch, stitch can be made not impact to its coiling first by stitch bending in coiling.
Description
Technical field
The utility model belongs to high frequency transformer technical field, and in particular to a kind of soft stitch high frequency transformer.
Background technique
High frequency transformer is as the most important component part of Switching Power Supply, in general, Switching Power Supply generally uses semibridge system
Circuit for power conversion, two switching transistors are connected in turn to generate high-frequency impulse wave when work, then pass through high frequency transformer
It is depressured, exports the alternating current of low-voltage.
High frequency transformer is provided with primary coil, secondary coil and stitch, the end of incoming cables of primary coil and secondary coil and
Leading-out terminal is connect with stitch, and high frequency transformer is arranged on circuit boards by stitch, is connect with the component on circuit board, is such as schemed
Shown in 1.Stitch is arranged on skeleton, and primary coil and secondary coil are arranged in the wire casing of skeleton, in order to not influence stitch pair
Pin is usually plugged in the outside of skeleton by the influence of coil-winding, but so needs for the line end of coil to be wound around
Outside the wire casing of skeleton, encountering connection when colliding with or being pullled between coil and stitch may be disconnected, and become high frequency
The reliability of depressor reduces.
Utility model content
The utility model provides a kind of soft stitch high frequency transformer, to solve in the prior art since coil is wound around skeleton
The external and problem that causes high frequency transformer reliability lower.
To achieve the above object, a kind of high frequency transformer of the utility model adopts the following technical scheme that
A kind of soft stitch high frequency transformer, including skeleton, magnetic core and coil, skeleton are provided with wire casing, the coil setting
In wire casing；It further include soft stitch, soft stitch is threaded through the edge of skeleton, and in the wire casing, the other end exists one end
The outside of skeleton；The one end of the soft stitch in wire casing connects the coil.
Further, the magnetic core includes the E body of two docking.
Further, the periphery of the coil and magnetic core is respectively arranged with corresponding insulating layer.
Further, the coil includes primary winding coil and secondary winding coil, and the wire casing includes armature winding
Wire casing and secondary windings wire casing, the primary winding coil setting exist in armature winding wire casing, the secondary winding coil setting
Secondary windings wire casing.
Stitch is threaded through the edge of skeleton by technical solution provided by the utility model, and the terminals of coil are connected
It is located at one end in wire casing to stitch, does not need the outside that the terminals of coil are located to skeleton, to solves in the prior art
Due to the problem that coil is wound around outside skeleton and causes high frequency transformer reliability lower；And since stitch is soft needle
Foot can be such that stitch does not impact to its coiling in coiling first by stitch bending.

Specific embodiment
The present embodiment provides a kind of high frequency transformers, and for solving, prior art medium/high frequency transformer reliability is poor to be asked
Topic.
High frequency transformer provided by the present embodiment, structural principle is as shown in Figure 2, Figure 3 and Figure 4, including skeleton 1, magnetic
Core 2 and coil 3, coil 3 include primary coil 31 and secondary coil 32.
Skeleton 1 includes primary coil slot 11, secondary wire ring recess 12 and through-hole 14, and primary coil 31 is arranged in primary coil
In slot 11, the setting of secondary coil 32 is set respectively in secondary wire ring recess 12, and in the outside of primary coil 31 and secondary coil 32
It is equipped with the insulating tape accordingly as its insulating layer.There are four soft pins 13, soft pin 13 to wear for setting on skeleton 1
On skeleton 1, the outside of skeleton 1 is arranged in one end, and the other end is arranged in primary coil slot 11 and secondary wire ring recess 12.
Magnetic core 2 includes the E body 21 and E body 22 of docking, as shown in figure 5, the intermediate raised portion 210 and E of E body 21
The intermediate raised portion 220 of body 22 is threaded through in the through-hole 14 of skeleton 1, and the periphery of magnetic core 2 is provided with insulating tape, should
Insulating tape is the insulating layer of magnetic core 2.
High frequency transformer provided in the present embodiment, in coiling first by soft pin 13 primary coil slot 11 and time
One end bending of grade coil slot 12, as shown in figure 3, being then set in skeleton 1 on coil winding machine by through-hole 13, using coil winding machine
Primary coil 31 is arranged in primary coil slot 11, by secondary coil 32 in secondary wire ring recess 12.
By primary coil 31 be arranged in primary coil slot 11, by secondary coil 32 in secondary wire ring recess 12 after, will be soft
The one end of matter pin 13 in primary coil slot 11 and secondary wire ring recess 12 is straight, then in primary coil 31 and secondary coil 32
It is external insulating tape is set, finally by the intermediate projections portion of the intermediate raised portion 210 of E body 21 in magnetic core 2 and E body 22
Divide 220 to be threaded through in the through-hole 14 of skeleton 1, and insulating tape is set outside iron core, completes the assembling of high frequency transformer.
