Abstract
The utility model discloses a transformer. The utility model adopts a technical scheme that the transformer comprises an iron core, wherein a primary coil and a secondary coil are wound around the iron core; and an insulating partition for insulating and separating the primary coil and the secondary coil insularly is arranged between the primary coil and the secondary coil. In the utility model, the primary coil and the secondary coil are wound around the iron core insular mutually, so the problem of insulation between the primary and secondary coils is solved and the manufacturing cost is reduced; and the coupling strength, which means the size and proportion of the primary and secondary coils, is adjusted by adjusting the distance between the primary and secondary coils during the manufacturing process. The insulating partition is arranged between the primary coil and the secondary coil, so the structure is simple and the manufacturing cost is low; and the prospective coupling effect can be achieved because the distance between the primary coil and the secondary coil can be adjusted and controlled during the manufacturing of the insulating partition.
Description
[technical field]
The utility model relates to a kind of transformer.
[background technology]
Distance between transformer and the secondary coil has determined the effect of coupling, the more little coupling effect of distance between primary coil and the secondary coil is good more, but too small primary coil and the secondary coil weak point of causing easily of distance leads between the coil, and be difficult for controlling accurately the distance between primary coil and the secondary coil when making, cause manufacturing cost to raise.Existing transformer is by the primary and secondary coil of transformer is realized power transfer on a concentric iron core, in order to guarantee safety requirements, insulation system has been proposed very high requirement, these requirements have limited further dwindling of volume of transformer, and the requirement to insulation system has simultaneously also promoted manufacturing cost.
[utility model content]
The utility model purpose is to have overcome deficiency of the prior art, provides a kind of simple in structure, low cost of manufacture, the transformer that is provided with insulating barrier between primary coil and secondary coil that coupling effect is good.
The utility model is achieved through the following technical solutions:
A kind of transformer is characterized in that comprising iron core, is arranged with primary coil and secondary coil on iron core respectively, is provided with primary coil and secondary coil insulation are separated insulating barrier between described primary coil and secondary coil.
Transformer as mentioned above, it is characterized in that described iron core comprises elementary winding iron core and secondary winding iron core, elementary winding iron core and secondary winding iron core are open core, lay respectively at insulating barrier both sides and opening towards insulating barrier, the iron core column number of described elementary winding iron core and secondary winding iron core equates and corresponding alignment.
Compared with prior art, the utility model has following advantage:
The utility model is wound on primary coil and secondary coil respectively on the iron core of mutually insulated, solved the insulating requirements problem between the primary and secondary coil, reduced manufacturing cost, in manufacture process, adjust stiffness of coupling, promptly adjust the size and the ratio of leakage inductance by the distance of adjusting between the primary and secondary coil.Between primary coil and secondary coil, be provided with insulating barrier, simple in structure, low cost of manufacture; Owing to just distance between primary coil and the secondary coil can be able to be adjusted control when having insulating barrier to make, reach predetermined coupling effect.

Fig. 1 is the utility model stereogram;
Fig. 2 is the utility model exploded view.
[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
A kind of transformer is characterized in that comprising iron core 1, is arranged with primary coil 2 and secondary coil 3 on iron core 1 respectively, is provided with insulating barrier 4 is separated in primary coil 2 and secondary coil 3 insulation between described primary coil 2 and secondary coil 3.
Described iron core 1 comprises elementary winding iron core 101 and secondary winding iron core 102, elementary winding iron core 101 and secondary winding iron core 102 are open core, lay respectively at insulating barrier 4 both sides and opening towards insulating barrier 4, the iron core column number of described elementary winding iron core 101 and secondary winding iron core 102 equates and corresponding alignment.
Also can use the iron core of sealing in the utility model, the insulating barrier opening be cooperated be clamped on the iron core, primary coil and secondary coil insulation are separated.
The utility model is wound on primary coil and secondary coil respectively on the iron core of mutually insulated, solved the insulating requirements problem between the primary and secondary coil, reduced manufacturing cost, in manufacture process, adjust stiffness of coupling, promptly adjust the size and the ratio of leakage inductance by the distance of adjusting between the primary and secondary coil.Owing to just distance between primary coil and the secondary coil can be able to be adjusted control when having insulating barrier to make, reach predetermined coupling effect.
