Description
Technical field
The utility model relates to the transformer technology field, specifically is meant a kind of SMD strong current transformer.
Background technology
Transformer is widely used at electric field, and a kind of transformer is wherein arranged, and is a lot of because the number of turns of secondary winding is lacked than the number of turns of elementary winding, and the electric current of the secondary end output of transformer is very big, is called as strong current transformer.This transformer uses face very wide.Strong current transformer of the prior art also comprises a kind of SMD strong current transformer that is used to be mounted on the circuit board.The secondary tap of this SMD strong current transformer is drawn by flat weld tabs, and weld tabs is provided with and is used for the flat surface that fits and weld with printed circuit board (PCB).Specifically combine shown in the accompanying drawing 1; SMD strong current transformer of the prior art comprises winding 01, secondary winding tap, skeleton 03 and primary tap 04; Winding is wrapped on the iron core; Winding comprises elementary winding and secondary winding, and the secondary winding tap is drawn by flat weld tabs 02, and weld tabs 02 is provided with and is used for the flat surface that fits and weld with printed circuit board (PCB).When but the weld tabs of this structure 02 uses in reality; If transformer is operated in the big environment of oscillation intensity; The flat surface place of weld tabs and printed circuit board (PCB) welding is easy to generate loosening, causes transformer and circuit board loose contact, thereby has reduced the stability of whole transformer.
The utility model content
The technical problem that the utility model will solve is to provide a kind of stability better SMD strong current transformer.
For solving the problems of the technologies described above; The technical scheme that the utility model provides is: a kind of SMD strong current transformer, and it comprises skeleton, iron core and winding, winding comprises elementary winding, secondary winding, primary tap and secondary winding tap; Elementary winding and secondary winding all are wrapped on the iron core; Iron core is through on the skeleton, and the number of turns of elementary winding is greater than the number of turns of secondary winding, and primary tap links to each other with the end of a thread on the elementary winding; Said secondary winding tap is the weld tabs that is welded to connect with winding the end of a thread, and described weld tabs is provided with installing hole.
After adopting above structure; The utlity model has following advantage: weld tabs is provided with installing hole, when SMD strong current transformer and the welding of printed circuit board (PCB) paster, can also with bolt SMD strong current transformer and printed circuit board (PCB) be reinforced through installing hole; Double fixed; Obviously stability is better, even SMD strong current transformer is worked in the big environment of oscillation intensity, the flat surface place of weld tabs and printed circuit board (PCB) welding also is not easy to become flexible.
As preferably, described installing hole is provided with internal thread, and the internal thread setting can directly be screwed into screw in the installing hole, reinforces convenient.
Further preferred, described weld tabs is two, and the installing hole on each weld tabs is two.The setting of two installing holes, bonding strength is bigger, and simultaneously the user can also optionally use in two installing holes one or two according to the position, hole of printed circuit board (PCB), and transformer is to the better adaptability of printed circuit board (PCB) like this.
