Description
Technical field
It is a kind of transformer of ER type that the utility model relates to.
Background technology
Usually, in order to drive electronics, need driving power, in order to this driving power is supplied to electronic installation, need power supply.This power supply comprise by commercialization electricity or other input powers be converted to expect power (such as, direct current (DC) power) transformer, existing common product such as the transformer of notebook computer is made up of transformer shell, internal coil, input lead and output lead, its effect is that alternating current is become direct current, and reduce voltage to certain scope, for notebook computer is powered.Its weak point is: when using summer, and because temperature is higher, transformer heat radiation is bad, and transformer can be awfully hot.If the coil of the too high meeting of transformer temperature to transformer is unfavorable, easily make coil aging, shorten coil useful life.And transformer temperature is too high also there is disaster hidden-trouble.
Utility model content
The purpose of this utility model is the transformer in order to solve a kind of ER type that above-mentioned the deficiencies in the prior art provide a kind of life-span long, safe.
To achieve these goals, the transformer of a kind of ER type designed by the utility model, it is characterized in that: comprise support body and iron core, support body comprises winding part and terminal connecting portion, coil is wound with in described winding part, described terminal connecting portion is connected with external connection terminals, above-mentioned iron core is inserted in described winding part, coil winding mode in described winding part is close around one deck for being disposed with from the bottom up, also rich with layer, also rich with layer, close winding layer, close winding layer, close around two layers and dredge around one deck, described terminal connecting portion cover has sleeve pipe.
Preferably, described iron core is formed by some laminations being adjacent to be stacked, and is provided with the electric insulation distance member separated by they laminations between described every two laminations, and every two laminations form space.
Preferably, described support body is provided with several through holes.
The transformer of a kind of ER type that the utility model obtains, it has multiple through hole for ventilating, and it has good heat dissipation, uses for a long time and can reduce temperature, can extension coil useful life, reduces disaster hidden-trouble; Transformer is widely used in multi-media sound system transformer, LED power transformer, top box of digital machine transformer, power supply adaptor, computer switch power transformer, monitor switch power transformer, various household appliances switching mode power supply transformer, this production product super quality and competitive price, meet customer need.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figures 1 to 5, the transformer that the utility model provides is conversion alternating voltage, the device of alternating current and impedance, when being connected with alternating current in primary coil, just exchange flux is produced in iron core (or magnetic core), make the transformer of a kind of ER type inducing voltage (or electric current) in secondary coil, it comprises support body 1 and iron core 3, support body 1 comprises winding part and terminal connecting portion 6, coil 2 is wound with in described winding part, terminal connecting portion 6 avris is provided with winding slot 10, make to allow terminal connecting portion 6 be connected with coil 2 by winding slot 10, described terminal connecting portion 6 is connected with external connection terminals 4, above-mentioned iron core 3 is inserted in described winding part, coil 2 canoe in described winding part is close around one deck 18 for being disposed with from the bottom up, also 17 are had mercy on layer, also 16 are had mercy on layer, close winding layer 15, close winding layer 14, close around two layer 13 and dredge around one deck 12, described terminal connecting portion 6 cover has sleeve pipe 7, between coil 2 and support body 1, dividing plate 5 is installed, can extension coil useful life.
Further, described iron core 3 is formed by some laminations being adjacent to be stacked, the electric insulation distance member separated by they laminations is provided with between described every two laminations, every two laminations form space, electric insulation distance member makes the oil when transformer is filled with oil can at they ambient dynamic, and electric insulation distance member can adopt such as mica, Merlon, ultrapas or PTFE sheet.
Further, described support body 1 is provided with several through holes; It has good heat dissipation, uses for a long time and can reduce temperature, can extension coil useful life, reduces disaster hidden-trouble.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For general technical staff of the technical field of the invention; without departing from the concept of the premise utility; its framework form can be flexible and changeable; just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by submitted to claims.
