Abstract
The utility model discloses a non-full-circle winding high-frequency transformer, which comprises a primary high-frequency transformer pillar and a secondary high-frequency transformer pillar, wherein the primary high-frequency transformer pillar is welded to the secondary high-frequency transformer pillar through a metal sheet. The non-full-circle winding high-frequency transformer cancels bridging jumper wires which are difficult in fabrication, accordingly improves the reliability of a transformer system, further greatly reduces the usage amount of copper wires, lowers the cost of the transformer system, is extremely simple in structure, and satisfies the utilization requirements of users.
Description
Technical field
The utility model relates to the transformer technology field, relates in particular to a kind of non-whole circle coiling high frequency transformer.
Background technology
Use (0.1～0.9 circle) when having non-whole circle winding when high frequency transformer design,, need to increase in addition the big cross section fly line of cross-over connection primary and secondary level transformer pillar as copper conductor in order to make the transformer flux balance.But, use this fly line to have following defective as copper conductor:
One. make difficulty.Because there is big voltage transformer system electric current to flow through this fly line, so the cross-sectional area of fly line must be very big, there are problems such as shaping difficulty in the fly line of cross-sectional area.
Two. the leakage inductance that causes transformer increases.Because this fly line is to be connected across the same side end of primary and secondary level transformer pillar, itself can not do any fixedly processing, so there is the problem that causes the transformer leakage inductance increase because fly line moves.
Three. the transformer copper consumption increases.Because having big is that transformer system electric current flows through this fly line, so the cross-sectional area of fly line must be very big, the big copper consumption of the cross-sectional area of fly line has also increased.
Make the cross-over connection fly line of difficulty so be badly in need of a kind of the cancellation, thereby improved the reliability of voltage transformer system, and significantly reduced the use amount of copper cash, reduced the high frequency transformer of the cost of voltage transformer system.
The utility model content
In order to obtain this cross-over connection fly line of making difficulty of having cancelled, thereby improved the reliability of voltage transformer system, and significantly reduced the use amount of copper cash, reduced the high frequency transformer of the cost of voltage transformer system, the utility model proposes new technical solution, particular content is as follows:
A kind of non-whole circle coiling high frequency transformer comprises main high frequency transformer post and secondary high frequency transformer post; Described main high frequency transformer post welds secondary high frequency transformer post by a sheet metal.
Described sheet metal is copper foil or other any sheet metal that can implement the utility model identical function on the pcb board.
Described main high frequency transformer post and secondary high frequency transformer post wherein together respectively are provided with a unsettled pin on the side end.
Utilize the copper foil on the pcb board to weld primary and secondary level transformer pillar respectively, by the electromagnetic induction effect in the copper foil, reached the identical function that fly line cross-over connection primary and secondary level transformer pillar plays with side end, simultaneously because the copper foil on the pcb board is extremely thin, and the slabbing structure, in case be not easy to be shifted after the welding well, so avoided fly line to make the making difficulty that copper conductor exists, copper consumption is big, and the defective of leakage inductance takes place easily.
The utility model produces following beneficial effect:
The utility model has been cancelled the cross-over connection fly line of making difficulty, thereby has improved the reliability of voltage transformer system, and has significantly reduced the use amount of copper cash, has reduced the cost of voltage transformer system, and structure is very simple, has satisfied user's user demand.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model mainly comprises main high frequency transformer post 1 and secondary high frequency transformer post 2; And main high frequency transformer post 1 welds secondary high frequency transformer post 2 by a sheet metal.
More preferably, described sheet metal is copper foil 3 or other any sheet metal that can implement the utility model identical function on the pcb board.
More preferably, described main high frequency transformer post 1 and secondary high frequency transformer post 2 wherein together respectively are provided with a unsettled pin 11 and 21 on the side end, that is to say that these two pins 11 and 21 all do not electrically connect.
Utilize the copper foil 3 on the pcb board to weld primary and secondary level transformer pillar 1 and 2 respectively, by the electromagnetic induction effect in the copper foil 3, reach fly line and be connected across the identical function that primary and secondary level transformer pillar 1 and 2 plays with side end, simultaneously because the copper foil 3 on the pcb board is extremely thin, and the slabbing structure, in case be not easy to be shifted after the welding well, so avoided fly line to make the making difficulty that copper conductor exists, copper consumption is big, and the defective of leakage inductance takes place easily.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to technical scheme described above and design.
Claims (3)
