Abstract
The utility model relates to a leading out end head of a foil winding of a transformer. The utility model is characterized in that a winding lead is integrated with a leading out end head, the leading out end head is a wire end head which is bent into 90 DEG, the end head can be oppositely folded or be folded several times, and in addition, a leading out wire can be cut into two sections or a plurality of sections of wires and can be bent into 90 DEG. The electrical resistance and thermal resistance can be reduced at the position of the leading wire of the winding by the utility model, the copper loss of the winding can be reduced, radiating area of the winding can be increased, and the reliability of the winding can be enhanced. The leading out end head is easy to produce, and special equipment is not available for the utility model.
Description
The utility model belongs to field transformer, particularly relates to a kind of transformer foil formula winding lead.
Existing transformer foil formula winding lead is that the lead line is welded on the lead (paper tinsel) of winding.The lead line is connected with winding conducting wire and needs welding equipment, and plumber's solder is used in some welding method such as soldering, because the scolder conductance is lower than winding conducting wire (paper tinsel) several times, and welding position heating under the high-power condition of transformer.Particularly high frequency transformer is little because of volume, and area of dissipation is little, during design often the pressing board limit value choose current density value, need to force cooling, heating in winding is difficult for solving, the welding ends head position that works long hours is easily broken.The exit of welding is prone to problems of welded quality owing to welding equipment or solder technology reason, makes the reliability decrease of paper tinsel formula winding.
The purpose of this utility model is at above-mentioned the deficiencies in the prior art part, proposes a kind of paper tinsel formula Transformer Winding lead structure new, that can overcome the prior art defective.
The technical solution of the utility model is such.The lead of transformer foil formula winding and lead are one, and with 90 ° of lead termination bendings, the lead termination of these bending 90 degree is lead.Except that this principal mode, the form of lead can have several forms as required under this principle.A kind of is can be with the lead of 90 ° of bendings doubling or number folding again; Another kind is that the lead termination is cut into two parts or several parts, again with 90 ° of their bendings.
The utlity model has following advantage:
1, the winding copper loss is descended, radiating condition is good, has reduced resistance and thermal resistance between lead-in wire and the lead (paper tinsel), does not have the lead weld heating phenomenon of prior art.
2, because lead and lead are one, improve the termination quality, guaranteed the reliability of winding.
3, the utility model be easy to implement, convenient and swift, do not need Special Equipment.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
Fig. 1 is 90 ° of schematic diagrames of the utility model bending.
Fig. 2 is 90 ° of termination doublings of the utility model bending structure chart.
Fig. 3 draws the lead termination for the utility model and cuts into 90 ° of schematic diagrames of the equal bending in lead termination of four parts.
As shown in Figure 1, (1) is wire terminals, and (2) are the lead of 90 ° of bendings.
As shown in Figure 2, (1) is wire terminals, and (2) are the lead of 90 ° of bendings, and (3) are the lead conduplication side.
As shown in Figure 3, (1) is wire terminals, (2) shear 90 ° of leads of back first part of bending for wire terminals, (3) for shearing 90 ° of leads of back second part of bending, (4) for shearing 90 ° of leads of the 3rd part of bending in back, (5) are for shearing 90 ° of leads of the 4th part of bending in back.
The form of above-mentioned lead is all implemented according to the design needs.
Claims (3)
1, a kind of lead of paper tinsel formula winding comprises the lead (paper tinsel) of paper tinsel formula winding it is characterized in that winding conducting wire and lead are one that lead is the lead termination of 90 ° of bendings.
2, the lead of paper tinsel formula winding according to claim 1 is characterized in that the lead of 90 ° of bendings can be doubling or number folding shape.
3, the lead of paper tinsel formula winding according to claim 1, the lead termination that it is characterized in that cutting into two parts or several parts all is 90 ° of shapes of bending.
