Description
Technical field
It is a kind of novel transformer 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.
PQ type high-frequency transformer skeleton is the winding bracket of high-power high-frequency transformer, along with renewal and the upgrading of the electrical safety laws and regulations of various countries, requires also to strengthen to the electric clearance of transformer and creepage distance thereupon.PQ type high-frequency transformer skeleton general in the market, after completing transformer winding, its electric clearance safe distance is only 3.9mm, and creepage distance is only 4.3mm, and fail safe is poor.
Utility model content
The purpose of this utility model is a kind of novel transformer providing a kind of life-span long, safe to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, a kind of novel transformer designed by the utility model, it is characterized in that: comprise skeleton and magnetic core, skeleton comprises winding part and terminal connecting portion, coil is wound with in described winding part, above-mentioned magnetic core is inserted in described winding part, described terminal connecting portion comprises primary pins and secondary pins, be wound around the wire bonds of part in primary pins and secondary pins, it is characterized in that: the distance of the end distance frame center of described secondary pins equals the distance of primary pins end distance frame center, coil winding mode in described winding part is close around one deck for being disposed with from the bottom up, winding layer placed in the middle, close around two-layer, winding layer placed in the middle, close around one deck and close around one deck.
Preferably, described primary pins and secondary pins are provided with coiling groove.
Preferably, described winding portion of its outer adopts high pressure P ET film adhesive tape double-coated.
Preferably, described skeleton is provided with several through holes.
A kind of novel transformer 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.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is Fig. 1 vertical view.

In figure: skeleton 1, coil 2, magnetic core 3, coiling groove 4, terminal connecting portion 6, primary pins 7, secondary pins 8, close around one deck 10, winding layer 11 placed in the middle, close around two-layer 12, winding layer 13 placed in the middle, close around one deck 14, close around one deck 15.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figures 1 to 4, 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 magnetic core (or magnetic core), make a kind of novel transformer inducing voltage (or electric current) in secondary coil, comprise skeleton 1 and magnetic core 3, skeleton 1 comprises winding part and terminal connecting portion 6, coil 2 is wound with in described winding part, above-mentioned magnetic core 3 is inserted in described winding part, described terminal connecting portion comprises primary pins 7 and secondary pins 8, be wound around the wire bonds of part in primary pins and secondary pins, the distance of the end distance frame center of described secondary pins equals the distance of primary pins end distance frame center, coil winding mode in described winding part is close around one deck 10 for being disposed with from the bottom up, winding layer 11 placed in the middle, close around two-layer 12, winding layer 13 placed in the middle, close around one deck 14 and close around one deck 15.
Further, described primary pins and secondary pins are provided with coiling groove 4, are convenient to coiling, and coiling groove can increase the outlet distance of primary pins and secondary pins, increase fail safe.
Further, described winding portion of its outer adopts high pressure P ET film adhesive tape double-coated, strengthens safety further.
Further, described skeleton is provided with several through holes, and it has good heat dissipation, uses for a long time and can reduce temperature, can extension coil useful life, reduces disaster hidden-trouble.
The transformer that the utility model obtains is described further: 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; The distance of the end distance frame center of described secondary pins equals the distance of primary pins end distance frame center, has zoomed out the distance of secondary pins welding lead to skeleton, thus has met higher safe distance requirement, avoided potential safety hazard.
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.
