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
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.
