Abstract
The utility model relates to a transformer skeleton which comprises a skeleton body, wherein the center of the upper surface of the skeleton body is provided with an iron core groove. The skeleton body is provided with coil grooves which are a primary coil groove and a secondary coil groove, insulating tape is adhered at the front end and the rear end of the upper surface of the primary coil groove, insulating tape is adhered at the front end and the rear end of the lower surface of the secondary coil groove, and the width of the insulating tape stretching out of the coil grooves is equal to the height of the coil grooves. According to the transformer skeleton, when a transformer is produced, the insulating tape can be folded upwards to enable coils to be wound inside the primary coil groove and the secondary coil groove conveniently. After the coils are wound inside the primary coil groove and the secondary coil groove, the insulating tape is adhered outside the coils, finally a plurality of silicon steel sheets are inserted into the iron core groove of the transformer skeleton, and production is completed. The step that the tape is wound outside the coils is omitted, and production efficiency of the transformer is improved.
Description
Technical field
The utility model relates to a kind of transformer framework, relates in particular to a kind of transformer framework of being convenient to transformer production, belongs to transformer parts technical field.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and 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.Transformer when producing, at first with coil in primary coil groove and secondary wire ring recess, outside coil, twine insulating tape then, then the multi-disc silicon steel sheet is inserted the formation iron core of transformer framework inner iron core groove, such mode of production is loaded down with trivial details, production efficiency is low.
Summary of the invention
The utility model purpose is for the deficiency that overcomes prior art the transformer framework of being convenient to transformer production to be provided.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of transformer framework; Comprise the skeleton body, the upper face center of said skeleton body has core slots, has the coil groove on the said skeleton body; Said coil groove is primary coil groove and secondary wire ring recess, and insulating tape is posted in the front and back end of said primary coil groove upper surface; Insulating tape is posted in the front and back end of the lower surface of said secondary wire ring recess; The width that said insulating tape stretches out the coil groove equals the height of coil groove.
Preferably, the length of said insulating tape is greater than the length of core slots and less than the length of skeleton body.
Preferably, said insulating tape is two-layer.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The transformer framework of the utility model, because insulating tape is posted in the front and back end of primary coil groove upper surface, insulating tape is posted in the front and back end of the lower surface of secondary wire ring recess; The width that insulating tape stretches out the coil groove equals the height of coil groove, when transformer when producing, can insulating tape upwards be turned up; Make things convenient for coil in primary coil groove and secondary wire ring recess, to twine; Coil twines in primary coil groove and secondary wire ring recess when accomplishing, and insulating tape is attached to outside the coil, at last the multi-disc silicon steel sheet is inserted to accomplish in the transformer framework inner iron core groove and produces; Save the step of outside coil, twining adhesive tape, improved the production efficiency of transformer.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the stereogram of the transformer framework of the utility model;
Accompanying drawing 2 is the user mode figure of the transformer framework of the utility model;
Wherein: 1, skeleton body; 2, core slots; 3, primary coil groove; 4, secondary wire ring recess; 5, insulating tape; 6, coil; 7, silicon steel sheet.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of transformer framework of the utility model shown in accompanying drawing 1; Comprise skeleton body 1; The upper face center of said skeleton body 1 has core slots 2; Have the coil groove on the said skeleton body 1, said coil groove is primary coil groove 3 and secondary wire ring recess 4, and insulating tape 5 is posted in the front and back end of said primary coil groove 3 upper surfaces; Insulating tape 5 is posted in the front and back end of the lower surface of said secondary wire ring recess 4; The width that said insulating tape 5 stretches out the coil groove equals the height of coil groove; The length of said insulating tape 4 is greater than the length of core slots 2 and less than the length of skeleton body 1.
The described a kind of transformer framework of the utility model shown in accompanying drawing 2; When transformer is being produced; Can insulating tape 5 upwards be turned up, make things convenient for coil 6 in primary coil groove 3 and secondary wire ring recess 4, to twine, coil 6 twines when accomplishing in primary coil groove 3 and secondary wire ring recess 4; Insulating tape 5 is attached to outside the coil 6; At last multi-disc silicon steel sheet 7 is inserted to accomplish in the core slots 2 in the skeleton body 1 and produce, saved the step of outside coil 6, twining adhesive tape, improved the production efficiency of transformer.
Above-mentioned transformer framework, insulating tape are two-layer, and insulation effect is best.
Below only be the concrete exemplary applications of the utility model, the protection range of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
