Description
Technical field
The present invention relates to a kind of magneticss, more particularly to a kind of high frequency transformer.
Background technology
At present in existing high frequency transformer, coil is all wound around on transformer coil holder, and then iron core is inserted into becoming
It is assembled into transformator in the cavity at depressor coil holder center.The deficiency of this mode is, the manufacture of a high frequency transformer
Cheng Zhong, it usually needs through more than ten roads or even thirty or forty procedure, the physics of the complicated manual course of processing and all kinds of raw material
Property makes so, and often resulting in very high refining losses affects product quality, or even causes substantial amounts of scrap products, and common is bad existing
As having: the coil holder of bakelite material is damaged, the pin of carbon steel material oxidation, the pins causing around pin deforms tiltedly askew, plastic material
Coil holder baking deformation, pin loosens, the wrongly installed position of iron core group of pairing causes that sensibility reciprocal is low, coil holder and iron core do not match and cause iron core
There is air gap and in turn result in that sensibility reciprocal is low, core slackness, coil holder and iron core mismatch and cause hi pot defective products etc. in docking.These
The problem in the industry cycle existing always, to the uncontrollable in a large number invisible cost causing on both domestic and external production, this makes transformator
Structure and production operation method have the Improvement requirement of urgency.
Therefore those skilled in the art are devoted to inventing a kind of high frequency transformer that can overcome above-mentioned some shortcomings.
Content of the invention
In view of the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of improved high frequency
Transformator.
For achieving the above object, the invention provides a kind of high frequency transformer, including iron core and coil, described coil is straight
Connect and be wound on iron core, described iron core upper end is provided with projection and iron core and is covered with conducting magnet core shell;Set in described conducting magnet core shell
There is the groove with projection cooperation.
Described iron core is t shape iron core;Described coil is the insulated conductor being wound in iron core, and insulated conductor end is installed with insulation
Sleeve pipe.
Described conducting magnet core shell is in the cup type of back-off, is provided with the groove of at least one depression in it;Described groove with set
The projection being placed in iron core upper end fastens;Between the projection of described fastening and groove, there is air gap.
It is provided with chassis below described iron core, through hole is provided with chassis;Described coil passes through insulated sleeve as extraction
Line is drawn from through hole.
The bottom of iron core is provided with the containing cavities for receiving lead-out wire of interior sky.
In order to ensure the abundant insulation between iron core and enamel-covered wire, coated insulation adhesive tape on described iron core.
There is magnetic saturation phenomenon for transformator in the case of preventing high current, in described groove, be provided with a pad.
Traditional high frequency transformer no matter when what model, its pairing iron core is all plane to interface, this knot
Structure easily causes assembling dislocation, and is all that side column is come on stage with center pillar in structure, therefore directly insulated conductor cannot be wound on ferrum
On core, it is assembled into transformator therefore, it is necessary to making coil with coil holder and being inserted into iron core.Insulated conductor is directly wound in by the present invention
On iron core, thus making the high frequency transformer meeting using needs;This mode is suitable for variously-shaped, model iron core.
The invention has the beneficial effects as follows: insulated conductor is directly wound on iron core the high frequency transformer of the present invention, by
Projection and the docking of groove, it is entirely avoided the risk of two iron core assemblies dislocation not in place, due to not needing to use line
Frame, saves cost.The high frequency transformer magnetic flux of the present invention is high, improves the use quality of high frequency transformer.

Specific embodiment
With reference to Fig. 1 to Fig. 3, the invention will be further described:
A kind of high frequency transformer, under the coil 2 including t-shaped rotational-like iron core 1, being directly wound in iron core, iron core 1
The chassis 10 of side and the conducting magnet core shell 3 covering in the cup type in back-off on iron core.Chassis 10 is provided with through hole, described line
Circle 2 is the insulated conductor being wound in iron core 1, and insulated conductor end is drawn from through hole as lead-out wire after passing through insulated sleeve 14.
The bottom of iron core 1 is provided with the containing cavities for receiving lead-out wire of interior sky.Coated insulation adhesive tape 13 on described iron core 1.
Described iron core 1 upper end is provided with projection 11, is provided with least one groove with projection 11 fastening in conducting magnet core shell 3
12, it is provided with a pad in described groove 12.Between the projection 11 of described fastening and groove 12, there is air gap.
Iron core 1 is t type revolution shape, and during manufacture, the chassis 10 of t shaped iron core 1 is detachably mounted on winding mould,
The longitudinal axis end of t shaped iron core 1 can be with winding mould synchronous axial system, and the longitudinal axis that t shaped iron core 1 is established is cylinder, 10, chassis
It is divided into circle.On the center pillar of iron core 1, first coated insulation adhesive tape 13, carries out the abundant insulation between iron core 1 and enamel-covered wire, made
Coat margin tape at random at longitudinal axis two ends in journey, gradually make coil 2 on demand, coil 2 is internal to be single coil or multi-thread
Circle is formed, and during multi-coil, requires according to the rules to carry out insulating tape between n1, n2 ns respectively to twine together with barricade width
Around the winding method of insulated conductor is identical with traditional method.
High frequency transformer also includes the cup type conducting magnet core shell 3 of a back-off, and conducting magnet core shell 3 is in closed, whole cover
On the longitudinal axis of t shaped iron core 1 being wound with coil, the surface wrap of coil 2 has insulating tape 13.

Place be provided with a groove 12 corresponding with projection 11.When conducting magnet core shell 3 is fastened with iron core 1, by projection 11 He
Groove 12 positions.And, lead-out wire outlet is offered on chassis 10, insulated sleeve 14 worn in advance by lead-out wire, then from through hole
Draw, therefore, do not have coil holder also can be fully achieved and coil holder identical purpose and function.
Fastened using above-mentioned projection 11 and groove 12, can avoid matching iron core 1 assembling dislocation, and by projection 11
Reserved air gap, or place pad when the present invention produces in groove 12, can prevent under high current, causing transformator magnetic to satisfy
With.
Compared with prior art, have made marked progress, the bottom of iron core 1 is provided with the containing cavities of interior sky, can be used for receiving
Lead, this high frequency transformer both can vertical be installed, and can install lying type again, it is possible to achieve arbitrarily installs for 360 degree.Existing same money
High frequency transformer cannot realize vertical, horizontal, three kinds of mounting means of lateral recumbent posture, now only changes the high frequency of other models
Transformator, a certain degree of sacrifice of being compelled to do in price or in electrical characteristic, the high frequency transformer of the present invention possesses three kinds of peaces
Dress mode, can meet the needs of different situations, enhance the suitability of high frequency transformer.
The preferred embodiment of the present invention described in detail above.It should be appreciated that those of ordinary skill in the art is no
Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technology in the art
