Description
Technical field
It is a kind of 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.
Transformer is application Faraday's electromagnetic induction law and raises or reduce the device of voltage, primarily of closed magnetic core and at least two group coils composition, coil around on magnetic core, for being elevated the voltage of alternating current, change impedance and isolating circuit.EE type transformer is a kind of transformer being made up of closed magnetic core two E type magnetic cores docking, magnetic core is connected to base, base is provided with bolt hole, need during use first base to be bolted to connection in wiring board, be fixed with the stitch of band to coil windings again, and then welded by tin stove, use inconvenience, the efficiency making wiring board is low.
Utility model content
The purpose of this utility model is a kind of 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 transformer designed by the utility model, it is characterized in that: comprise skeleton and iron core, skeleton comprises winding part and terminal connecting portion, coil is wound with in described winding part, above-mentioned iron core is inserted in described winding part, it is characterized in that: described terminal connection part is arranged with multiple pin frame, pin frame is provided with through hole, groove is had between every two pin frames, the stitch of described winding part is through described through hole, described winding portion of its outer is coated with double-deck PET film adhesive tape, described coil winding mode is by multilayer parallel and is arranged in order the coil winding that forms on iron core.
Preferably, described skeleton is provided with several through holes.
A kind of transformer that the utility model obtains, have applied widely, operating frequency is high, operating voltage range is wide, power output is large, thermal stability high, is widely used in programme-controlled exchange electromechanical source, liquid crystal display power supply, high power UPS inverter, computer power supply and various miniaturized electronics instrument.

Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of Fig. 1 side.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the structural representation of coil.
Fig. 5 is the circuit theory diagrams of transformer.
In figure: skeleton 1, coil 2, iron core 3, terminal connecting portion 5, pin frame 6, through hole 7.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figures 1 to 5, a kind of 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 a kind of transformer inducing voltage (or electric current) in secondary coil, comprise skeleton 1 and iron core 3, skeleton 1 comprises winding part and terminal connecting portion 5, coil 2 is wound with in described winding part, above-mentioned iron core 3 is inserted in described winding part, described terminal connecting portion 5 is provided with multiple pin frame 6, pin frame 6 is provided with through hole 7, groove is had between every two pin frames, the stitch of described winding part is one-body molded with terminal connecting portion 5 through described through hole 7, realize not needing welding, the length shortening coil also can produce heat due to line length, therefore also solve heat problem, described winding portion of its outer is coated with double-deck PET film adhesive tape, strengthens safety further, described coil 2 canoe is by multilayer parallel and is arranged in order the coil winding that forms on iron core, and this form can make that operating frequency is high, operating voltage range is wide, power output is large, thermal stability high.
Further, be convenient to coiling, groove can increase the outlet distance of primary pins and secondary pins, increases fail safe.
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.
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.
Claims (2)
1. a transformer, it is characterized in that: comprise skeleton and iron core, skeleton comprises winding part and terminal connecting portion, coil is wound with in described winding part, above-mentioned iron core is inserted in described winding part, it is characterized in that: described terminal connection part is arranged with multiple pin frame, pin frame is provided with through hole, groove is had between every two pin frames, the stitch of described winding part is through described through hole and terminal connecting portion, described winding portion of its outer is coated with double-deck PET film adhesive tape, described coil winding mode is by multilayer parallel and is arranged in order the coil winding that forms on iron core.
