Abstract
The utility model discloses a framework of a novel transformer and the novel transformer. The framework of the novel transformer comprises a winding part, a primary terminal board, a secondary terminal board and a protecting cover. The primary terminal board is arranged at the first end of the winding part, the protecting cover is mounted on the winding part and wraps the winding part, and the secondary terminal board is arranged on the protecting cover. The novel transformer comprises the framework of the novel transformer. Compared with the prior art, due to the fact that the detachable protecting cover wraps the winding part, the secondary terminal board is arranged on the protecting cover, an additional anti-packaging adhesive tape is of no need, the secondary terminal board does not need to be led out through a fly line, and thus the safety requirements of the transformer can be met. The production operation difficulty of the transformer is reduced, and the production cost of the transformer is reduced.
Description
Technical field
The utility model relates to Switching Power Supply, especially relates to a kind of novel transformer skeleton and a kind of novel transformer.
Background technology
As shown in Figure 1, be the structural representation of traditional RM6 type skeleton, there is following problem in it: 1) PIN is very little to the distance of winding slot, causes electric clearance and the creepage distance of primary coil to secondary PIN or secondary coil to elementary PIN can not satisfy the safety requirement; 2) behind the assembling magnetic core, PIN is very little to the distance of magnetic core, causes elementary PIN or secondary PIN can not satisfy the safety requirement to electric clearance and the creepage distance of magnetic core.
Prior art often adopt the anti-package adhesive tape or mode that secondary employing fly line is drawn to solve the problems of the technologies described above.The mode of anti-package adhesive tape is for increasing winding anti-package adhesive tape to overcome the not enough problem of primary coil and secondary pin spare safe distance, increase magnetic core anti-package adhesive tape to solve the not enough problem of safe distance between secondary pin and magnetic core, but the anti-package adhesive tape is difficult to production operation, causes production cost too high; And adopt fly line to draw secondary mode, and there is the difficult and high problem of production cost of production operation too, simultaneously, adopt the transformer of fly line deriving structure, it is difficult that power supply is produced plug-in unit, and hidden danger of quality such as broken string, rosin joint appear in weak strength easily behind the plug-in unit.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of novel transformer skeleton is provided, and satisfying under the prerequisite that safety requires, and reduces the production operation difficulty of transformer, reduces the production cost of transformer.
Another technical problem to be solved in the utility model is that a kind of transformer that adopts above-mentioned transformer framework is provided.
A kind of novel transformer skeleton comprises winding section, primary side daughter board and secondary end daughter board, also comprises protective jacket; Described primary side daughter board is arranged on first end of described winding section; Described protective jacket is installed on the described winding section and envelopes described winding section; Described secondary end daughter board is arranged on the described protective jacket.
Preferably, described winding section is provided with first positioner, and described protective jacket is provided with second positioner that is complementary with described first positioner, and described protective jacket is installed on the described winding section by described first positioner.
Preferably, described first positioner is the back springing type reference column, and described second positioner is the location hole that is arranged on the described protective jacket.
A kind of novel transformer comprises transformer framework, magnetic core and coil, it is characterized in that: described transformer framework is aforementioned any described novel transformer skeleton.
Preferably, described coil comprises from inside to outside the ground floor arranged, the second layer, the 3rd layer and the 4th layer, wherein ground floor comprises that 26 ~ 36 astragals directly are the lead of 0.07 ~ 0.27mm, the second layer comprises that 5 ~ 15 astragals directly are the lead of 0.27 ~ 0.47mm, the 3rd layer comprises that 7 ~ 17 astragals directly are the lead of 0.07 ~ 0.27mm, and the 4th layer comprises that 24 ~ 34 astragals directly are the lead of 0.07 ~ 0.27mm.。
Compared with prior art, because the utility model adopts detachable protective jacket to coat the winding section, and the secondary end daughter board is arranged on the protective jacket, the anti-package adhesive tape also need not the secondary fly line that carries out is drawn the safety requirement that namely can satisfy transformer thereby feasible employing transformer framework of the present utility model need not separately, reduce the difficulty of transformer production operation, also reduced the production cost of transformer.
