Abstract

The utility model discloses a large-power rectifier transformer of a charger. The large-power rectifier transformer comprises an iron core post, and a primary coil and a secondary coil wound on the iron core post. The large-power rectifier transformer is characterized in that the secondary coil is formed by vertically winding a flat aluminum row and is divided into a plurality of wire cake layers isolated by an insulation bakelite block between the wire cake layers; the secondary coil includes two coil output ends arranged on both ends of the secondary coil, and a plurality of middle taps in the middle of the secondary coil; and output terminals are welded on the coil output ends and the middle taps. The large-power rectifier transformer provided by the utility model is convenient in winding, easy in welding the output terminals and compact in structure, and has the advantages of small added loss of the secondary coil and high short-circuit resistance and mechanical strength. The wire cakes of the secondary coil are isolated by the insulation bakelite block between, thereby realizing insulation between the wire cakes and improving the heat dissipation effect of the secondary coil.

Description

A kind of charger power rectifier transformer
Technical field
The utility model relates to the transformer technology field, particularly a kind of charger power rectifier transformer.
Background technology
In charger, often need use rectifier transformer.The wire terminal etc. of going out that continous way that winding transposition wire that the limit winding is made up of many insulated lead or multiple conducting wires forms or helical winding, transversal ventilation dispel the heat road and leading-out terminal thereof of paying of the power rectifier transformer that uses in the charger industry at present constitutes; The technical problem of its existence is: 1, because its leading-out terminal is multiple conducting wires and the welding of outlet termination; Therefore welding is relatively more difficult, and technology is also complicated; 2, because adopt the continuous winding of many insulated lead coiling to replace and online cake between be provided with the transversal ventilation heat radiation road that cushion block constitutes, therefore, not only complex process, and loop construction is not compact yet; 3, owing to adopt multiple conducting wires, the length of each root lead can not be absolute consistent, and the width of lead also can not obtain too smallly, therefore can cause the supplementary load loss of winding bigger, and it is relatively poor to bear the short circuit mechanical strength simultaneously.
The utility model content
The utility model technical problem to be solved is to the existing existing problem of charger power rectifier transformer a kind of charger power rectifier transformer to be provided; The secondary coil of this charger power rectifier transformer adopts aluminium row coiling, has solved the existing problem of existing charger power rectifier transformer.
The utility model technical problem to be solved can realize through following technical scheme:
A kind of charger power rectifier transformer; Comprise iron core column and primary coil and secondary side coil on the iron core column, it is characterized in that said secondary side coil adopts the aluminium row of flat perpendicular around forming; This secondary side coil is divided into some layer line cakes, adopts the insulating cement wooden unit to separate between the line cake; This secondary side coil is provided with two coil outputs and several centre taps, and said coil output is arranged on the two ends of secondary side coil, and some centre taps are arranged on the secondary side coil centre position; On said coil output and centre tap, be welded with lead-out terminal.
In a preferred embodiment of the utility model, close on coil output and centre tap the top that layer line cake in have only a circle coil, all the other line cakes have two circle coils.
The utility model has been owing to adopted technical scheme as above, has that coiling is convenient, the welding lead-out terminal is easier to, the secondary side coil supplementary load loss are little, the Short Circuit withstand mechanical strength better, the advantage of compact conformation.Owing between the line cake of secondary side coil, utilize the insulating cement wooden unit to separate, promptly realize the insulation between the line cake in addition, improved the ventilation and heat of secondary side coil again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with accompanying drawing, further set forth the utility model.
Referring to Fig. 1; A kind of charger power rectifier transformer; Comprise iron core column (not shown) and primary coil (not shown) and secondary side coil 100 on the iron core column; Its secondary side coil 100 adopts the aluminium row 110 of flat perpendicular around forming, and this secondary side coil 100 is divided into some layer line cakes, adopts 2~3mm insulating cement wooden unit 120 to separate between the line cake; This secondary side coil 100 is provided with 130,140 and two centre taps 150,160 of two coil outputs, and coil output 130,140 is arranged on the two ends of secondary side coil 100, and two centre taps 150,160 are arranged on secondary side coil 100 centre positions; On coil output 130,140 and centre tap 150,160, be welded with lead-out terminal 131,141,151,161.Close in that layer line cakes of coil output 140 and centre tap 150,160 tops and have only a circle coil, have two circle coils in all the other line cakes.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
