Description
Technical field
The utility model relates to transformer, is specifically related to a kind of winding construction that is used for transformer.
Background technology
In the prior art, transformer can be used for changing voltage, changes impedance and isolating circuit, hereat often is applied in the multiple electronic product, and winding then is in order to finish the necessary assembly of changing voltage in the transformer.According to various user demands, existing winding has many structural improvement.
See also Fig. 1, it is depicted as one of common winding construction 1 in the existing transformer, and it mainly is integrally formed, is broadly divided into one first winding sheet 11 and one second winding sheet 12 on the structure, each tool one terminals 13.At first, winding construction 1 is electroplated winding construction 1 subsequently with a conductive material (for example copper) drawing again, to prevent the oxidation of winding sheet and to be beneficial to tin in the follow-up welding.Afterwards, stick insulating tape, carry out the punching press second time then, use insulating tape is shaped and overlaps with winding construction 1 at the tow sides of winding construction 1.And when practical application, then be the winding construction 1 that above-mentioned steps is finished,, the first winding sheet 11 and the second winding sheet 12 overlapped along the doubling of A-A ' line, form the structure of similar coil, and just form a complete winding behind the winding construction 1 in conjunction with certain number of turn.
Yet, in second time punching course, often cause edge within the first winding sheet 11 and the second winding sheet 12, produce the burr of easy insulation-piercing adhesive plaster, and then make the first winding sheet 11 may produce to contact with 12 of the second winding sheets to cause short circuit, so that can't reach the electrical functionality that former project organization requires; Person more, in the process of doubling overlapping, the junction of the first winding sheet 11 and the second winding sheet 12 easily produces fracture because of the application of force is improper, cause the electric connection of 12 of the first winding sheet 11 and the second winding sheets to be lost efficacy, and then cause winding construction 1 normally to play a role.Again, winding construction 1 after doubling overlaps, its two terminals 13 will directly be linked on the printed circuit board (PCB), and in follow-up processing procedure, the printed circuit board (PCB) of winding construction 1 is still needed through the welding of tin stove, the insulating tape that pasted on the winding construction 1 this moment is easy because of melting loss takes place high temperature, destroys insulating properties.
As previously mentioned, defective appears in the winding construction of existing transformer easily in manufacture process, and then causes problems such as short circuit, electric connection inefficacy and insulation are destroyed.
The utility model content
The purpose of this utility model is, at the problems referred to above of prior art, a kind of winding construction that is used for transformer is provided, it is convenient to the making of winding integral body, and can be after finishing the tool good stable, unlikelyly be short-circuited, electrically connect between the winding sheet and lost efficacy and insulation such as is destroyed at problem.
For achieving the above object, provide a kind of winding construction that is used for a transformer, comprise one first conducting strip, one second conducting strip, an insulation ring plate and an a connection piece.First conducting strip has one first open annular portion and one first connecting hole; Second conducting strip has one second open annular portion and one second connecting hole; The insulation ring plate has one the 3rd connecting hole, is arranged between this first conducting strip and this second conducting strip, in order to isolate partly electrically connecting of this first open annular portion and this second open annular portion; This first connecting hole, this second connecting hole and the 3rd connecting hole pass in connector system, connecting this first conducting strip, this second conducting strip and this insulation ring plate, and electrically connect this first conducting strip and this second conducting strip.
As mentioned above, the utility model makes up with connector the primary clustering separate processes of winding construction again with it, so, conductive component and insulation assembly can separate punching press separately to be handled, and can avoid that punching press simultaneously produces the problem of burr and the fracture of winding construction junction in prior art; More the person in prior art, needs to use insulating tape to stick in the restriction of winding sheet, and the insulation ring plate can adopt more resistant to elevated temperatures material, has bigger elasticity.
