Description
Technical field
The utility model relates to a kind of composite type drum stand, and a kind of composite type drum stand that provides transformer first order lead and second level lead to twine and assemble particularly is provided.
Background technology
At present common on the market transformer is shown in TaiWan, China M346097 number, M339762 number, I291183 patent case, the common part of above-mentioned patent case is that its drum stand of transformer of each patent case possesses first winding region and second winding region that one-body molded configuration is arranged, because first winding region and second winding region are shaped on the drum stand, therefore produce following point:
1, first winding region and second winding region can't twine lead simultaneously, must twine at first winding region to finish, and just can twine second winding region again, have therefore slowed down speed of production.
2, when bobbin and iron core before group is found into transformer, just often whether first winding region on the filler test bobbin and the lead of second winding region, because first winding region and second winding region are shaped on the same drum stand, when the lead that tests out the one winding region is defective products, then need whole drum stand is squeezed into defective products, do not meet economic benefit in fact.
3, because the operating voltage of second winding region of transformer is a high pressure, so if do not isolated, the situation that then has creeping discharge produces, in order to prevent that this creeping discharge from influencing other electronic components, often must add an outer cover in addition, isolating second winding region and other electronic components, so for transformer just many one programs in the upright process of group, and also increased production cost.
For improving the disappearance of its bobbin of traditional transformer, the utility model applicant proposes a kind of bobbin structure, as the utility model applicant application and obtain shown in the TaiWan, China M304106 patent case of checking and approving, it includes a second level around pipe, and this second level is provided with two second level that supply second level lead winding around the district around pipe; And one the second level intercept cover around pipe; this second level around pipe intercept be arranged with two can be installed with the second level around pipe around the pipe disposal area; in order to isolate and protection second level lead; and be provided with the first order that to twine for first order lead between the disposal area around the district around pipe two; not only has the effect of isolating and protecting second level lead, so can upright time and the cost of saving group.
Though can utilizing this second level to intercept cover around pipe, M304106 patent case isolates second level lead, but this second level forms the opening that supplies the second level to insert around pipe around pipe obstruct cover around below, pipe disposal area, cause the second level of the second level on pipe around distinguishing and twine the second level lead of the second level around the district, its below is exposed fully outside, cause the first order around distinguishing and the creepage distance deficiency of the second level between the district, and perfoliate punch-through between the generation electrode, cause transformer or arround the damage of electronic component.
