Abstract
The invention discloses a transformer framework with flexible winding columns. The flexible transformer framework comprises a framework body, a primary coil groove and a secondary coil groove are opened on the framework body, at least two groups of pins are symmetrically arranged on the outer surface of the framework body, and winding columns connected with the pins are arranged inside the primary coil groove and the secondary coil groove; holes are opened in the winding columns; and the winding columns are sheet-shaped and flexible. According to the transformer framework with flexible winding columns, starting ends of windings inside coil grooves penetrate through holes of the winding columns to be fixed, windings are wound inside the coil grooves to form coils, tail ends of windings penetrate through holes of the other winding columns to be fixed, the winding columns are pressed down to enable insulating tapes to wind, and starting ends and tail ends of the windings are easy to wind, accordingly, starting ends and tail ends of windings are prevented from being exposed outside, windings are prevented from being broken, and the service life of the transformer is increased.
Description
Technical field
The present invention relates to a kind of transformer framework, relate in particular to the bent transformer framework of a kind of wrapping post, belong to transformer parts technical field.
Background technology
Transformer framework is a requisite part in the transformer.Existing transformer framework generally is divided into two kinds of structures, i.e. I-shaped structure and king's font structure.For the transformer framework of I-shaped structure, primary coil and secondary coil successively are wound in the groove of transformer framework, complex manufacturing process, and only depend on insulating paper to separate between primary coil and the secondary coil, insulation effect is poor; Transformer framework for I-shaped structure; Primary coil and secondary coil are wound in respectively in the primary coil groove and secondary wire ring recess that has up and down; Shim by transformer framework is separated; Have better insulation effect, and be convenient to the maintenance of primary coil and secondary coil, therefore used widely.For king's font transformer framework, the transformer framework outer surface generally is arranged with two groups of stitch, and the initiating terminal of the coiling in primary coil and the secondary coil links to each other with two stitch respectively with end.In order to make coil be difficult for loosening scattering; Be typically provided with the wrapping post that links to each other with stitch that has the hole on the transformer framework; During coiling, the hole of at first initiating terminal of coiling being passed wrapping post is fixed, and is wrapped in coiling in the coil groove then and forms coil; The end that then will wind the line passes the hole of another wrapping post and fixes, and at last the coil that winds is twined with insulating tape.Though such structure can increase the stability of transformer work; But owing to existing wrapping post stretches out outside the coil groove usually, and can not bend, insulating tape twines the initiating terminal and the end that are difficult for coiling and enwinds; Make the initiating terminal of coiling expose outside with terminal; Because the fracture of the factor in the various external worlds makes transformer damage, influenced the useful life of transformer easily.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: the initiating terminal and the terminal not bent transformer framework of wrapping post of easy fracture that have proposed a kind of coiling.
Technical solution of the present invention is achieved in that the transformer framework that a kind of wrapping post is bent; Comprise the skeleton body; Have primary coil groove and secondary wire ring recess on the said skeleton body; The outer surface of said skeleton body is arranged with at least two group stitch, is provided with the wrapping post that links to each other with stitch in said primary coil groove and the secondary wire ring recess; Have the hole on the said wrapping post; Said wrapping post is laminar and it is bent.
Preferably, said wrapping post is provided with semi-circular groove.
Preferably, the outer surface of said skeleton body is arranged with four groups of stitch.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The transformer framework that wrapping post of the present invention is bent; Owing to be provided with the wrapping post that links to each other with stitch in primary coil groove and the secondary wire ring recess, have the hole on the wrapping post, wrapping post is laminar and it is bent; After the hole that the initiating terminal of the coiling in the coil groove passes wrapping post is fixed; Be wrapped in coiling in the coil groove and form coil, after the hole that the end of coiling passes another wrapping post is fixed, in the coil groove, press wrapping post; Making insulating tape twine easily enwinds the initiating terminal and the end that wind the line; The initiating terminal that has prevented coiling has exposedly avoided coiling easily because the fracture of the factor in the various external worlds with terminal outside, has increased transformer useful life; Because wrapping post is provided with semi-circular groove, makes coiling can place semi-circular groove, make coil be difficult for loosening scattering, increased the stability of transformer work.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of the bent transformer framework of wrapping post of the present invention;
Stereogram when accompanying drawing 2 presses down for the wrapping post of the bent transformer framework of wrapping post of the present invention;
Wherein: 1, skeleton body; 2, primary coil groove; 3, secondary wire ring recess; 4, stitch; 5, wrapping post; 6, hole; 7, semi-circular groove.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Like accompanying drawing 1, the bent transformer framework of of the present invention a kind of wrapping post shown in 2; Comprise skeleton body 1; Have primary coil groove 2 and secondary wire ring recess 3 on the said skeleton body 1; The outer surface of said skeleton body 1 is arranged with at least two group stitch 4, is provided with the wrapping post 5 that links to each other with stitch 4 in said primary coil groove 2 and the secondary wire ring recess 3; Have hole 6 on the said wrapping post 5; Said wrapping post 5 is provided with semi-circular groove 7; Said wrapping post 5 is laminar and it is bent.
After the hole 6 that the initiating terminal of the coiling in elementary coil groove 2 and the secondary wire ring recess 3 passes wrapping post 5 is fixed; Be wrapped in primary coil groove 2 and the secondary wire ring recess 3 interior coils that form to coiling; After the hole 6 that the end of coiling passes another wrapping post 5 is fixed; In the coil groove, press wrapping post 5, make insulating tape twine easily the initiating terminal and the end that wind the line are enwinded, prevented that the initiating terminal of coiling and end are exposed outside; Avoid coiling easily because the fracture of the factor in the various external worlds, increased transformer useful life; During coiling, coiling can place in the semi-circular groove 7 that wrapping post 5 is provided with, and makes coil be difficult for loosening scattering, and has increased the stability of transformer work.
When the transformer framework that above-mentioned wrapping post is bent, the outer surface of skeleton body were arranged with four groups of stitch, result of use was best.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
