Abstract

The utility model relates to an iron core transformer with E model lamination, which relates to a small power transformer, comprising a silicon steel laminated iron core and a coil wound on the iron core. The silicon steel laminated iron core is formed by the butt-joint of two same E type laminated iron cores in opposite directions; seaming adopts glue spreading adhesion or argon arc-welding to make that an external seaming is welded. The utility model has the advantage of simple structure and only a punched iron core lamination mould can be used to simplify the manufacture process of laminated iron cores and the assembly technique of a transformer; therefore, the utility model can be widely used in various small power transformers.

Description

Iron core transformer with E model lamination

The utility model relates to a kind of wattage transformer.

The following wattage transformer of 1000AV generally all is that coil unshakable in one's determination by silicon steel laminations and that be wound on the iron core constitutes in the prior art, and its structural shape has shell-type and two kinds of laminated cores of core type then to mainly contain " EI " type and two kinds of structural shapes of " C " type.The E shape silicon steel laminations that the laminated core of " EI " type is adopted and " I " shape silicon steel laminations form with punch press and mould punching, though the flushing technology of core lamination is very simple, but the assembly technology of transformer is quite complicated, adopts the method for E shape lamination and I shape lamination interdigitation that two kinds of laminations are inserted in the coil piecewise usually.It is smooth to adopt this method that the iron core that is inserted into is difficult for, and presentation quality is also very poor.The laminated core of C type is the laminated core of adopting C shape silicon steel laminations to make two symmetries, makes it being connected into transformer behind the coil of packing into again.The assembly technology of this pattern transformer is fairly simple, but the manufacture craft of laminated core is very complicated, and needs a series of special equipment.

The purpose of this utility model is the novel transformer of the easy advantage of design a kind of having concurrently " EI " type simple advantage of laminated core manufacturing and C type laminated core technology for assembling transformers, to simplify the manufacturing process of transformer, reduces production costs.

To achieve these goals, the utility model adopts two identical E type laminated cores in opposite directions to being connected into the laminated core of transformer, and seam crossing employing gluing is bonding or adopt argon arc welding that external joint is welded.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model butt joint E type laminated core transformer.

Accompanying drawing 1 is the structural representation of butt joint E type laminated core transformer.

With reference to the accompanying drawings 1, the utility model butt joint E type laminated core transformer is to be made of silicon steel laminations unshakable in one's determination 1 and the coil 2 that is wound on unshakable in one's determination 1, laminated core 1 is to be docked in opposite directions by two identical E type laminated cores to form, three core limbs of two E types laminated core dock respectively, and seam crossing employing gluing is bonding or adopt the hydrogen arc weldering that external joint is welded.

The utility model is simple in structure, only needs a kind of mould of punching out core lamination, has simplified the manufacture craft of laminated core and the assembly technology of transformer, has reduced production cost.Therefore, the utility model can be widely used as various wattage transformers.

Claims

1, a kind of wattage transformer, coil unshakable in one's determination by silicon steel laminations and that be wound on the iron core constitutes; Of the present utility modelly be characterised in that described silicon steel laminations iron core is to be docked in opposite directions by two identical E type silicon steel laminations iron cores to form, seam crossing adopts and is coated with glue bond or adopts argon arc welding to make the external joint welding.
