Abstract
The utility model discloses a toroidal transformer with a shell. The toroidal transformer with the shell comprises a magnetic ring, a base and the shell, wherein a primary coil is wound on the magnetic ring, and the magnetic ring on which the primary coil is wound is arranged in the base; and the shell is sheathed on and matched with the base, and the product formed by combining the shell with the base is provided with a secondary coil. The toroidal transformer with the shell has the advantages that by arranging the magnetic ring in the shell, the stress of wire stocks can not act on the magnetic ring during the penetration of the wire stocks, therefore, the influence of the stress on the inductance value of the magnetic ring is avoided and the stability of volume production of the products is increased; and the toroidal transformer with the shell is considerably convenient and practical, is better in economic prospect and can generate better social benefits.
Description
Technical field
The utility model relates to a kind of ultra-thin transformer, specifically is to adopt a kind of toroidal transformer with shell on the electricity-saving lamp.
Background technology
At present, the toroidal transformer that electricity-saving lamp is used, because be the isolated form transformer, most of mode that adopts is the magnetic core spraying, and secondary use three layer insulation wire, to reach the purpose of " isolation ", this kind mode has two shortcomings: the one, and the magnet ring sprayed coating is destroyed easily in the process of threading, thereby causes playing the effect of " isolation "; The 2nd, the three layer insulation wire cost is very high.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provides a kind of toroidal transformer with shell, by magnet ring being placed on shell inside, the stress of wire rod can not act on the magnet ring when making the threading material, thereby avoided the influence of stress, made that batch process goods stability is higher the magnet ring inductance value.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:
A kind of toroidal transformer with shell, comprise magnet ring and base, also comprise shell, on described magnet ring, wear around primary coil, the magnet ring of wearing around primary coil is arranged in the base, described outer cover suit is provided with secondary coil on the goods after shell and the base combination on the base that is used.
On described shell and base, be provided with the notch that cooperatively interacts and use.
Described base is provided with the salient point that is used for fixing shell.
Beneficial effect: the toroidal transformer of band shell of the present utility model, by magnet ring is placed on enclosure, the stress of wire rod can not act on the magnet ring when making the threading material, thereby avoided the influence of stress to the magnet ring inductance value, make that batch process goods stability is higher, very convenient practicality has good economic outlook, can produce good social benefit.

Embodiment
Below in conjunction with accompanying drawing the utility model is further explained
As shown in Figure 1, toroidal transformer for band shell of the present utility model, comprise magnet ring 3, base 1 and shell 2, on described magnet ring 3, wear around primary coil, the magnet ring of wearing around primary coil 3 is arranged in the base 1, described shell 2 is sleeved on the base 1 that is used, and on the goods after shell 2 and base 1 make up secondary coil is set.
As shown in Figure 2, be the base 1 of the toroidal transformer of band shell of the present utility model.Base 1 is provided with salient point 11, notch 13 that passes lead-in wire that is used for fixing shell 2 and the fairlead 12 that is used to draw lead-in wire.Salient point 11 is arranged on the opening part of notch 13.
As shown in Figure 3, the magnet ring 3 of the toroidal transformer of band shell of the present utility model.
As shown in Figure 4, be the shell 2 of the toroidal transformer of band shell of the present utility model.The use that cooperatively interacts of shell 2 and base 1, shell 2 is provided with first notch 21 that is used with notch 13.
The toroidal transformer of band shell of the present utility model, on magnet ring 3, wear earlier around primary coil, after finishing, the magnet ring 2 of putting on coil is positioned on the base 3, and the lead-out wire of primary coil drawn by the notch on the base 1 13, form semi-finished product, shell 2 is combined on the semi-finished product, during assembling, first notch 21 on the shell 2 is corresponding with notch 13 and salient point 11 on the base 1, as shown in Figure 1, wear on goods around secondary coil after combination is finished, lead-out wire is drawn by the fairlead on the base 1 12 after finishing again.
The utility model provides a kind of method of the toroidal transformer with shell; its concrete application approach is a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
