Abstract
The utility model discloses an annular transformer convenient to wind, comprising an annular iron core, and a primary winding and a secondary winding, which are sequentially wound on the annular iron core, wherein a polyester thin film is wound outside the primary winding, an annular insulating clapboard is arranged between the primary winding and the secondary winding, a plurality of radial blocking ribs protruding from the surface of the insulating clapboard are arranged on the surface opposite to the secondary winding of the insulating clapboard in the radial direction, the dimensions of fan-shaped regions enclosed by each two blocking ribs on the annular insulating clapboard are the same. The annular transformer convenient to wind disclosed by the utility model is simple in structure, the annular insulating clapboard is added between the primary winding and the secondary winding and a plurality of blocking ribs are arranged on the annular insulating clapboard to not only play an insulating function, but also guarantee simpler and more convenient winding of the secondary winding, and the annular transformer is used for effectively guaranteeing the winding density of the secondary winding during the winding process so as to guarantee uniform voltage gradient between the coils, and improving the application effect of the annular transformer.
Description
Technical field
The utility model relates to a kind of transformer, is specially a kind of toroidal transformer of being convenient to coiling.
Background technology
Toroidal transformer is a large type of electronic transformer, has been widely used in the higher electronic equipment of home appliance and other specification requirement, and its main application is as power transformer and isolating transformer.Toroidal transformer is widely used in the aspects such as computer, Medical Devices, telecommunication, instrument and lighting, has the good ratio of performance to price, and good output characteristic and antijamming capability are arranged.Toroidal transformer of the prior art includes annular core and is wound on successively armature winding and secondary winding on the annular core, armature winding is wound with polyester film outward, the coiling of secondary winding directly has influence on the result of use of toroidal transformer, if secondary winding is inhomogeneous along the density of annular coiling, then can affect the uniformity of the voltage gradient between coil turn, and then make the result of use of toroidal transformer relatively poor.
The utility model content
The purpose of this utility model provides a kind of toroidal transformer of being convenient to coiling, the coiling density to occur easily when the coiling inhomogeneous to solve toroidal transformer traditional in the prior art, affect the uniformity of the voltage gradient between coil turn, and then affect the problem of toroidal transformer result of use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of toroidal transformer of being convenient to coiling, include annular core and be wound on successively armature winding and secondary winding on the annular core, described armature winding is wound with polyester film outward, it is characterized in that: the insulating barrier that is provided with annular between described armature winding and secondary winding, radially be provided with radial several block reinforcements that protrude from the insulating barrier surface on the described insulating barrier one side relative with secondary winding, the sector region size that per two block reinforcements surround on the insulating barrier of annular is identical.
Described a kind of toroidal transformer of being convenient to coiling is characterized in that: chamfering all is arranged at the inside and outside edge of described insulating barrier.
Described a kind of toroidal transformer of being convenient to coiling is characterized in that: described annular core adopts the annular ferrite core of PC40 material.
The beneficial effects of the utility model are:
The utility model is simple in structure, production cost is low, annular insulating barrier is set up in employing between armature winding and secondary winding, and the design of several block reinforcements is set at insulating barrier, not only play the effect of insulation and reinforcement winding stability, also so that the coiling of secondary winding is more simple and convenient, guaranteed that effectively the density of secondary winding when coiling is even, and then make the voltage gradient between coil turn more even, guarantee the electric property of toroidal transformer, promoted the result of use of toroidal transformer.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of insulating barrier in the utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of toroidal transformer of being convenient to coiling, include annular core 1 and be wound on successively armature winding 2 and secondary winding 3 on the annular core 1, the armature winding 2 outer polyester films that are wound with, 3 of armature winding 2 and secondary winding are provided with the insulating barrier 4 of annular, radially be provided with radial several block reinforcements 5 that protrude from insulating barrier 4 surfaces on the relative one side of insulating barrier 4 and secondary winding 3, the sector region size that per two block reinforcements 5 surround on the insulating barrier 4 of annular is identical.
Chamfering all is arranged at the inside and outside edge of insulating barrier 4.Annular core 1 adopts the annular ferrite core of PC40 material.
The utility model adopts in armature winding 2 and 3 designs of setting up annular insulating barrier 4 of secondary winding, several block reinforcements 5 on the insulating barrier 4 are divided into several sector regions with insulating barrier 4, so that secondary winding 3 can be according to the fixing number of turn of sector region coiling when coiling; Sector region is less with respect to annular insulating barrier 4 areas of integral body, so density is easier to control during coiling, guaranteed that effectively the density of secondary winding 3 is even, and then so that the voltage gradient between coil turn is more even.And the stability of winding has also been strengthened in the design of adopting insulating barrier 4.
