Abstract

The utility model relates to an iron core of a transformer, which comprises an upper iron core and a lower iron core matched with the upper iron core, wherein the upper iron core and the lower iron core are respectively arranged to be of an E-shaped structure. A plurality of notches are arranged at the bottom of the upper iron core, a plurality of protrusions are arranged at the top of the lower iron core, and the protrusions are contained in the notches. Through matching of the protrusions and the notches, the iron core of the transformer not only enables the upper iron core and the lower iron core to be tightly assembled together, but also has roles of locating and guiding and is convenient to produce and assemble.

Description

A kind of transformer core

[technical field]

The utility model relates to a kind of building block of transformer, is specifically related to a kind of transformer core, belongs to the transformer technology field.

[background technology]

The transformer core of prior art is shown in Figure of description 1, and it comprises and is superimposed together by two iron cores that are the E font and forms a complete transformer core.The location of above-mentioned iron core when assembling comparatively bothers, and production efficiency is low; And assembling is also fallen apart after accomplishing easily.

For solving the problems of the technologies described above, necessary a kind of structure improved transformer core that has is provided, to overcome said defective of the prior art.

[utility model content]

For addressing the above problem, the purpose of the utility model be to provide a kind of simple in structure, assembling is quick and the transformer core of accurate positioning.

For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of transformer core, and it comprises upper core and the lower core that matches with upper core; Said upper core and lower core all are the setting of E font structure; Be provided with some breach in the bottom of said upper core; Be provided with some convexities in the top of said lower core, said convexity is contained in the breach.

The transformer core of the utility model further is set to: the cross section semicircular in shape structure of said convexity.

Compared with prior art; The utlity model has following beneficial effect: the transformer core of the utility model cooperates through protruding and breach; Not only can upper core and lower core be fitted together securely, and can also play the effect of location, guiding, make things convenient for production and assembly.

[description of drawings]

Fig. 1 is the structural representation of the transformer core of prior art.

Fig. 2 is the structural representation of the transformer core of the utility model.

[embodiment]

See also shown in the Figure of description 2, the utility model is a kind of transformer core, and it is made up of upper core 1 and lower core 2 two parts of matching with upper core 1.

Wherein, said upper core 1 all is the setting of E font structure with lower core 2.Be provided with some breach 11 in the bottom of said upper core 1.Be provided with some protrudingly 21 in the top of said lower core 2, said protruding 21 are contained in the breach 11.Said protruding 21 cross section semicircular in shape structure also can be multiple shapes such as square, rhombus.

The transformer core of the utility model cooperates with breach 11 through protruding 21; Not only can upper core 1 and lower core 2 be fitted together securely; And the effect that can also play the location, lead; Make things convenient for production and assembly, promptly as long as convexity 21 and breach 11 are cooperated, this upper core 1 just can be assembled with lower core 2 and put in place.

Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.

Claims

1. a transformer core is characterized in that: comprise upper core and the lower core that matches with upper core; Said upper core and lower core all are the setting of E font structure; Be provided with some breach in the bottom of said upper core; Be provided with some convexities in the top of said lower core, said convexity is contained in the breach.

2. transformer core as claimed in claim 1 is characterized in that: the cross section semicircular in shape structure of said convexity.
