Description
Technical field
What the invention relates to a kind of transformer goes out line method and structure thereof, refers to that especially a kind of coiling of transformer directly goes out line method and structure thereof.
Background technology
Transformer is the electronic building brick that often uses in the various electric equipment.See also Fig. 1, it is the structural representation of traditional transformer.As shown in Figure 1, conventional transformer structure mainly comprises group (magnetic core assembly) 1, one winding base 2, one elementary coiling (primary winding coil) (not shown) unshakable in one's determination, level coiling (secondary winding coil) (not shown) and housing 3 etc.Wherein, elementary coiling and secondary rolling thread are wrapped in respectively in the winding base 2, and produce electrical interaction to reach the purpose of voltage transitions with iron core group 1.Group 1 unshakable in one's determination is generally EI sections heart group (EI-core) or EE sections heart group (EE-core), 3 of housings comprise housing pedestal 31 and cover plate 32, when housing pedestal 31 during with cover plate 32 combinations, iron core can be organized 1 be fixed in winding base 2 in, by this to constitute transformer body.
Please consult Fig. 1 again; winding base 2 through elementary coiling and secondary rolling thread winding usually can be with leading-out terminal and many copper wire leads 21 that coated by polyvinyl chloride (PVC) of coiling; 22,23 welding mutually, each copper wire lead 21; 22; 23 free end then is provided with a fixed terminal, and each fixed terminal is copper wire lead 21,22 fixedly; 23 in the perforation of printed circuit board (PCB) (not shown), by this so that transformer and printed circuit board (PCB) form conducts.In addition, the visual conditional request of transformer and being fixed on electric equipment housing or the printed circuit board (PCB).
The assembling and the outlet method of traditional transformer are as follows: at first, shown in Fig. 2 (a), elementary coiling (not shown) and secondary rolling thread (not shown) are wound in respectively in the winding base 2, the material of wherein elementary coiling and secondary rolling thread is good with copper cash; Then, after coiling, the winding portion that is wound in winding base 2 is coated with adhesive tape (tape) 24, elementary coiling this moment and secondary rolling thread can be pulled out four winding terminals 25,26,27 and 28; Then, shown in Fig. 2 (b), in regular turn first winding terminal 25 is welded mutually with the first copper wire lead 21 that polyvinyl chloride (PVC) is coated, second winding terminal 26 welds mutually with the second copper wire lead 22 that polyvinyl chloride (PVC) is coated, the 3rd together welds with the 3rd copper wire lead 23 that polyvinyl chloride (PVC) is coated mutually with the 4th winding terminal 27 and 28, and wherein the 3rd and the 4th winding terminal 27 and 28 can be respectively elementary and winding terminal secondary rolling thread.
For preventing three copper wire leads 21,22,23 copper wire exposed section contact with each other and avoid each solder joint puncture polyvinyl chloride (PVC) even dielectric film and cause transformer short-circuit to burn, traditional approach needs copper wire exposed section and each pad part are isolated mutually with adhesive tape and pad.Therefore after above-mentioned steps, shown in Fig. 2 (c), with first winding terminal 25 and the first copper wire lead 21 reflexed upwards, and paste one or a several layers of adhesive tape 291 and a pad 292, with covering copper wire exposed section and its welding portion.Then, with second winding terminal 26 and the second copper wire lead 22 reflexed upwards, and paste one or a several layers of adhesive tape 293 and a pad 294, with covering copper wire exposed section and its welding portion.At last, also with the 3rd winding terminal 27 and the 4th winding terminal 28 with the 3rd copper wire leads 23 reflexed upwards, and paste one or several layers of adhesive tape 295 and a pad 296 outside it.Then, the free end of above-mentioned copper wire lead 21,22,23 is stamped fixed terminal separately so that these copper wire leads 21,22,23 are fixed and electric connection to printed circuit board (PCB).
Then, please consult Fig. 1 again, the winding base 2 after iron core group 1 and the coiling is combined, and insert in the housing pedestal 31, and then cover cover plate 32, and will roll over pin give a discount fixing after, whole transformer is soaked vaseline water, again through finishing the making of transformer behind the baking procedure.
Subsequently, the fixed terminal of the copper wire lead 21,22,23 of above-mentioned transformer is inserted in the perforation of printed circuit board (PCB) (not shown), by this so that transformer conduct with printed circuit board (PCB) formation.
Yet by above-mentioned transformer device structure and assemble method as can be known, traditional transformer outlet method need be used many adhesive tapes and pad, so structure comparatively complexity and cost height.In addition, owing to need repeat the action that adhesive tape and pad coat, so be difficult for carrying out and productivity ratio can't improve.In addition, because winding terminal (copper cash) need be soldered to each self-corresponding copper wire lead again, so the quality of transformer also can make rate of finished products reduce because of the problem of solder joint puncture.And, be the copper wire lead of dielectric film with polyvinyl chloride (PVC), because the fusing point of polyvinyl chloride lower (about 105 degree), the heatproof degree of transformer integral body is limited with causing.Moreover, therefore the free end of copper wire lead need increase material and actions such as fixed terminal again because of being directly fixed on printed circuit board (PCB), so not only causes the waste of material, also can increase the step of manufacturing process, empty hyperplasia is produced cost and the productivity ratio that reduces manufacturing process.
Therefore, how to overcome the defective of said structure and outlet method, and then provide a kind of transformer to go out line method and structure thereof, real in pressing for the problem of solution at present.
Summary of the invention
