Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of improved EI shaped iron core transformer.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, is comparatively common electronic component, almost in all electronic products, all can relate to use, gradually becomes one of electronic component indispensable in electronic circuit.
At present, known power transformer comprises core transformers and appendiron core transformer.Appendiron core transformer is EI type blade inserting transformer, the feature of this transformer is that processing is simple, coil winding is convenient, and when its deficiency is to carry out lamination inserted sheet, lamination is all to adopt inserting mode, then fill crane span structure, if inserted sheet is not tight between lamination, easily form gap, transformer just has vibrations, cause transformer noise excessive, the problem such as even occur uttering long and high-pitched sounds; Meanwhile, easily there is no-load current situation rambunctious in such transformer, easily produces eddy current, thereby cause having leakage field phenomenon after energising between lamination; Lamination is manually welded into a whole if adopt after inserting and having folded, not only complex process, and also efficiency is lower, cannot realize large-scale production.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of improved EI shaped iron core transformer is provided, between this improved its lamination of EI shaped iron core transformer, compact conformation is firm, can effectively avoid the problems such as the vibrations, noise, leakage field of transformer, and manufacture process automation more, thereby improve production efficiency.
The purpose of this utility model is achieved through the following technical solutions:
A kind of improved EI shaped iron core transformer is provided, comprise skeleton and the iron core that is sheathed on described skeleton, on described skeleton, be wound with armature winding enamelled wire and secondary winding enamelled wire, the elementary lead-in wire of described armature winding enamelled wire is connected with elementary connector, the secondary lead of described secondary winding enamelled wire is connected with secondary connector, described iron core is to weld to inserting stack argon arc welding the iron core forming by multi-disc E matrix and I matrix, on described skeleton, be provided with resettable fuse, described iron core bottom welding has an installation fixed base plate.
Wherein, described E matrix is E type silicon steel sheet, and described I matrix is I type silicon steel sheet.
Wherein, the thickness of described E type silicon steel sheet and described I type silicon steel sheet is 1mm～3mm.
Wherein, on described installation fixed base plate, be provided with screw mounting hole.
The beneficial effects of the utility model:
Its E matrix of the improved EI shaped iron core of one of the present utility model transformer and I matrix are to inserting after stack, employing argon arc welding is welded, make more compact structure between lamination, described iron core bottom welding has an installation fixed base plate, make transformer more stable firmly, thereby effectively avoid the problem such as vibrations, noise and leakage field of transformer, and adopt argon arc welding welding to substitute artificial welding, greatly improve the manufacturing automation degree of transformer, thereby improve the production efficiency of transformer.
Accompanying drawing explanation

Embodiment
With the following Examples the utility model is further described.
The improved EI shaped iron core of one of the present utility model transformer, as shown in Figure 1 to Figure 3, comprise skeleton 1 and the iron core 2 that is sheathed on skeleton 1, on skeleton 1, be wound with armature winding enamelled wire 3 and secondary winding enamelled wire 4, the elementary lead-in wire 5 of armature winding enamelled wire 3 is connected with elementary connector 7, the secondary lead 6 of secondary winding enamelled wire 4 is connected with secondary connector 8, iron core 2 is made up of inserting stack multi-disc E matrix and I matrix, preferably, described E matrix is E type silicon steel sheet, and described I matrix is I type silicon steel sheet.More preferably, the thickness of described E type silicon steel sheet and described I type silicon steel sheet is 1mm～3mm.The lamination rear employing argon arc welding welding that superposeed finally forms an argon arc welding sealing wire 12 on iron core 2, completes the making of iron core 2, adopts the iron core 2 of above-mentioned structure, more compact structure between its lamination.In addition, on skeleton 1, be also provided with resettable fuse 11 for the protection of this improved EI shaped iron core transformer.Simultaneously, there is an installation fixed base plate 9 at the bottom welding of iron core 2, install on fixed base plate 9 and be provided with screw mounting hole 10, this mounting plate 9 of setting up makes transformer more stable firmly, thereby effectively avoid the problems such as vibrations, noise and the leakage field of transformer, and adopt argon arc welding welding to substitute artificial welding, greatly improve the manufacturing automation degree of transformer, thereby improve the production efficiency of transformer.
