Coiling.
A kind of high-frequency transformer skeleton from band edge blanking bar described in the present embodiment, the second primary winding slot include
A grooves 52, B grooves 53, C grooves 54 and D grooves 55；The A grooves 52 are located at the side of the first primary winding slot 51 with B grooves 53；The C grooves
54 are located at the opposite side of the first primary winding slot 51 with D grooves 55；The B grooves 53 located at 52 and first primary winding slot 51 of A grooves it
Between；The C grooves 54 are located between 55 and first primary winding slot 51 of D grooves.A kind of height from band edge blanking bar described in the present embodiment
Frequency power transformer skeleton, the spacing between the 53 and first primary winding slot 51 of B grooves are more than 54 and first primary winding slot 51 of C grooves
Between spacing.A kind of high-frequency transformer skeleton from band edge blanking bar described in the present embodiment, the second subprime winding slot bag
E grooves 62, F grooves 63, G grooves 64 and H grooves 65 are included；The E grooves 62 are located at the side of first secondary winding groove 61 with F grooves 63；Institute
State the opposite side that G grooves 64 are located at first secondary winding groove 61 with H grooves 65；The F grooves 63 are located at E grooves 62 and first secondary winding groove
Between 61；The G grooves 64 are located between H grooves 65 and first secondary winding groove 61.It is a kind of from band edge blanking bar described in the present embodiment
High-frequency transformer skeleton, the spacing of the two neighboring secondary rolling thread groove 21 is equal.
Traditional high frequency transformer, in order to meet the requirement of safety, it is necessary to want jacketed pipe in the end of a thread or line tail, caused by disadvantage
End is can not to use automatic coil winding machine coiling, can only use single shaft coiling machine hand winding operation so that production efficiency is low, quality
It is unstable.In order to solve this problem, primary winding slot 11 is arranged to by applicant：53 and first primary winding slot 51 of B grooves it
Between spacing be more than spacing between C grooves 54 and D grooves 55, the spacing between C grooves 54 and D grooves 55 is more than the primary of C grooves 54 and first

Away from；The voltage that applicant passes through according to each primary winding slot 11 is obtained after multiple calculate, according to the difference by voltage swing,
Different spacing is designed, resistance to pressure request is high to be made apart from increase, otherwise is reduced, if spacing is identical, according to safety, for pressure-resistant
It is required that high the end of a thread is because resistance to pressure is not met, it is necessary to increase sleeve pipe；Therefore the structure of the present embodiment causes the resistance to pressure of transformer
Meeting safety, it is not necessary to increase sleeve pipe so that it can use automatic coil winding machine coiling, by taking the transformer of 7 winding as an example,
Having must use traditional handicraft to make during sleeve pipe, need for 200 people's seconds around complete 7 windings, and after cancelling sleeve pipe, using automatic winding
Rubber coating machine and end blanking bar rubber coating machine cooperate, it is only necessary to 20 people's seconds, 10 times of work efficiency is improved, and in the feelings of cost of manufacture inconvenience
Quality is more secure under condition.
A kind of high-frequency transformer skeleton from band edge blanking bar described in the present embodiment, the secondary rolling thread groove 21 also include
I grooves 7；The I grooves 7 are located at the side of H grooves 65.When there is 3 secondary windings, it is desirable to 6 the end of a thread, that is, need 6 wire casings.
And tradition often arranges 6 pin skeletons and there was only 5 wire casings, there have been two-wire altogether in the phenomenon of a wire casing, needs increase by one by safety
Individual sleeve pipe.Therefore, in one I groove 7 of the secondary outside of stitch 414 increase, two-wire groove altogether is avoided, so one can be cancelled after ledger line groove
Individual sleeve pipe.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this
The spirit and scope of utility model technical scheme.
