Description
Technical field
The present invention relates to technical field of transformer manufacturing, more particularly, to a kind of transformator be easy to and manufacture and assemble.
Background technology
In prior art, common transformator is winding-type transformer, and great majority are to utilize two wires (enamel-covered wire) rotating around being located on same iron core, form the first siding ring connecting power end respectively, and connect the second siding ring of load end.Between this first siding ring and this second siding ring, produced induced voltage depends on the coil ratio of this first siding ring and this second siding ring.When above-mentioned common winding-type transformer needs to change its output voltage, at least must change the number of turn and the number of turns of its second siding ring, it is therefore necessary to the concrete specification correspondence for each transformator is designed manufacturing.Consequently, it is possible to the inconvenience in production certainly will be caused, and the winding process of coil is relatively complicated, and manufacturing cost is higher, and does not meets the demand of economic benefit.
In addition, low-voltage, High-current output characteristic application in, owing to the second siding ring of transformator must use the wire (enamel-covered wire) of bigger external diameter, cause and between each coil turn, form bigger gap, the volume of integrated transformers not only can be made to present non-rational increase, and will also result in eddy current (Eddy) loss and increase, form the disappearance in application.
Improve constantly output electric current to meet second siding ring and save the demand of winding space, Fig. 1, Fig. 2 show a kind of transformer device structure, if its iron core 7 specifically including that 9, two relative joints of coil holder and the thin metal sheet 8 of dry thickness tens to hundreds of micron.Described iron core 7 is provided with main core 71 and multiple sidepiece 72 central with week side respectively, is formed and accommodate space 73 between main core 71 and each sidepiece 72, and receiving space 73 is in communication with the outside by multiple breach 74 being located at sidepiece 72 side.Coil holder 9 is located in the receiving space 73 of iron core 7, and coil holder 9 central authorities are provided with the first through hole 91 can being linked on main core 71.The outer circumferential side of coil holder 9 is provided with and can be used for being wound around once winding 92(coil) wire casing, and the both sides up and down of wire casing form the location division 931 protruded respectively by dividing plate 93.Two dividing plates 93 are provided with, at the most at one end angles, the junction block 94 that can stretch out outside iron core 7 by breach 74, on each junction block 94 respectively at least provided with one with once wind the binding post 941 that 92 both ends are connected.Each sheet metal 8 is provided with the second through hole 81 can being linked on two location divisions 931 in central authorities, makes the main core 71 of the vertical first through hole 91(iron core 7 of each sheet metal 8) superposition.Second through hole 81 can be in communication with the outside by the separate slot 82 being located between angle, sheet metal 8 one end, makes each sheet metal 8 can form two pole feet 83 separated and can stretch out outside iron core 7 by breach 74 at this separate slot 82.
This transformator, when assembling, arranges the obstruct ring plate 84 of insulation between each sheet metal 8, and each sheet metal 8 can be made to form secondary winding.This structure superposes respectively due to each sheet metal 8 in the way of perpendicular with main core 71 bearing of trend of iron core 7, when reality is applied, though eddy current (Eddy) loss can suitably be reduced, but has bigger overall leakage inductance simultaneously.
It addition, Fig. 3, Fig. 4 show another kind of transformer device structure, if its sheet metal 80 specifically including that coil holder 90 dry thickness tens to hundreds of micron and E shape iron core 70 of two relative joints.Coil holder 90 is provided with the first through hole 901 of horizontal expansion, and the outer circumferential side at the first through hole 901 is provided with multiple groove 902, can be used for being wound around once winding 903(coil in each groove 902).Coil holder 90 is respectively arranged at the two ends with junction block 904 the first through hole 901,904 is provided with and once winds the binding post 905 that 903 both ends are connected wherein on a junction block.Each sheet metal 80 bends in n shape respectively, it is coated on the outer circumferential side (also will can once wind 903 outer circumferential sides being located at sheet metal 80) of groove 902 for parallel first through hole 901, and the pole foot 801(being provided with extension equidirectional with binding post 905 at the both ends of each sheet metal 80 is secondary winding).
This transformator, when assembling, utilizes cover body 802 upper shield with suitably receiving space 803 on coil holder 90 and sheet metal 80.Cover body 802 is provided with the second through hole 804 corresponding to the first through hole 901, again the main core of central authorities of two E shape iron cores 70 stretched into the first through hole 901 of coil holder 90 by second through hole 804 at cover body 802 two ends respectively and contact, another kind can be formed and utilize sheet metal 80 as the transformer device structure of second siding ring.This structure due to each sheet metal 80 be fit the main core of E shape iron core 70 direction arrange, be therefore effectively reduced leakage inductance.But, (once bend after deforming owing to this sheet metal 80 is the most bent when assembling, be not easy with hands bending make its reinstatement) characteristic, cause it open with the structure of horizontal (the main core of iron core is as horizontal expansion), there is no the product of vertical (the main core of iron core is for vertically extending) structure, have a strong impact on multiformity and the competitiveness of product.
