Abstract
The utility model discloses a copper sheet for a transformer winding. The copper sheet is provided with two pins in contact with the exterior, an inner ring of the copper sheet is annular, and the annular bottom of an outer ring is in a rectangular shape provided with an outward protrusion. By means of the copper sheet, as the rectangular bottom edge is adopted in the outer ring, the operation of wrapping the copper sheet with insulated rubber tape is conveniently carried out, and the production speed is increased.
Description
Technical field
The utility model relates to a kind of Transformer Winding copper sheet with straight flange, belongs to electric component technical field.
Background technology
In DC-DC low-voltage, high-current product, for meeting properties of product, former secondary all uses copper sheet as winding.In order to coordinate the shape of magnetic core, copper sheet is to be all generally annular (circle) inside and outside being designed to.
But this annular design faces a kind of problem in actual production: because copper sheet top is for circular, in the time of encapsulate band, only there is a point to contact with adhesive tape, and extremely difficult coated, seriously reduce production efficiency; In the time putting into mould punching, due to the contact of point, location is inaccurate, causes requirement size to be difficult to ensure card equally simultaneously, and product reliability is low.
Summary of the invention
For the defect of prior art, the utility model discloses a kind of copper sheet with new geometry design, this copper sheet is used as the magnetic core winding of transformer not affecting under the through-flow prerequisite of copper sheet, reduces to have processed difficulty, has improved again the reliability of product.
For achieving the above object, the utility model is achieved through the following technical solutions:
The winding copper sheet of transformer, copper sheet has two pins with external contact, and the inner ring of copper sheet is annular, and the bottom of outer ring annular is the rectangle with evagination.
Further, copper sheet is coated with insulating tape.
By the change on said structure, in the time of coated insulation adhesive tape, only adhesive tape need to be wound around along the rectangular edges doubling of bottom, greatly improve production efficiency, simultaneously due to the existence on rectangle base, in the time of punching, be easy to location.
Brief description of the drawings
Figure 1A, 1B be respectively winding of the present utility model copper sheet adopt the coated procedure chart of insulating tape and be covered to complete after design sketch.
Embodiment
With reference to Figure 1A, winding copper sheet of the present utility model, opening part has two pins 11 and is used for being connected with outside, and the inner ring 10 of copper sheet is annular, and the outer ring 12 of copper sheet is annular substantially, has outwardly rectangle 13 in annular bottom.
In the time being wound around insulating tape 2, only insulating tape can need be completed rolling winding well along the base of rectangle.
Claims (2)
1. the winding copper sheet of transformer, is characterized in that copper sheet has and two pins of external contact, and the inner ring of copper sheet is annular, and the bottom of outer ring annular is the rectangle with evagination.
2. copper sheet according to claim 1, is characterized in that copper sheet is coated with insulating tape.
