Description
Technical field
The present invention relates to a kind of electric equipment, especially relate to a kind of electromagnetic induction device.
Background technology
At present, electromagnetic induction device such as transformator is electronic building brick commonly used in various electric equipment, some large scale electrical equipment such as LCD TVs develop towards large scale, large scale needs big power, big power needs to use thicker wire rod, and the frequency of circuit work is higher, so using multi cord line to be twisted into the mode of thick line more.
As it is shown in figure 1, tradition electromagnetic induction device structure mainly comprises iron core group 10 ' and coil windings 20 ', coil windings uses multi cord twisted wire to be wrapped in iron core group 10 ', and produces electrical interaction with iron core group 10 '.The lead-foot-line of existing multi cord twisted wire is without fixing device, when it inserts on wiring board, and the problem that foot contracting can be there is, caused the phenomenon that scolding tin after wave-soldering is bad；Additionally, after the lead-foot-line scolding tin of multi cord twisted wire, outward appearance can be in irregularly shaped, for meeting the different lead-foot-line specifications after scolding tin, the hole on wiring board have to reach greatly, and lead-foot-line could insert smoothly, so wiring space meeting scaled-back of wiring board, wiring board, after crossing wave-soldering, needs to carry out repair welding operation, it is to avoid produce stannum hole problem.
As shown in Figures 2 and 3, when the lead-foot-line of existing multi cord twisted wire is fixed on the terminal 30 ' of electromagnetic induction device, or it is arranged on electromagnetic induction device both sides, causes electromagnetic induction device planar dimension to increase；Or it is arranged on top or the bottom of electromagnetic induction device, cause electromagnetic induction device height to increase；During additionally, the lead-foot-line of multi cord twisted wire is fixed on terminal, loop current can produce unnecessary conduction loss on terminal just runner multi cord twisted wire on terminal.
Summary of the invention
Based on this, it is necessary to the problem existed for above-mentioned background technology, it is provided that a kind of electromagnetic induction device optimizing efficiency of element, the space availability ratio of increase wiring board wiring and reducing component size.
For achieving the above object, the invention discloses a kind of electromagnetic induction device, it includes iron core, pedestal and coil windings, described pedestal is fixing with described iron core to be connected, on described pedestal, fixing has pin set, and described coil windings uses multi cord litz construction, and described multi cord twisted wire is provided with lead-foot-line, described multi cord twisted wire is wound on pedestal, and described lead-foot-line is fastened in described pin set.
Wherein in an embodiment, described pedestal side offers holding hole, and described pin set is immobilizated in holding hole.
Wherein in an embodiment, described pin set uses conductive material manufacture.
Wherein in an embodiment, described pin set uses copper material manufacture.
Wherein in an embodiment, described pin set is cylinder lamellar.
Wherein in an embodiment, described pin set is semi-closed structure.
Wherein in an embodiment, described lead-foot-line is fixed together by soldering with pin set.
In sum, electromagnetic induction device of the present invention is by the pin set of the conduction of clamping on pedestal, scolding tin is coordinated to be connected fixing with pin set for the lead-foot-line of multi cord twisted wire, utilize the fixing position-limiting action that pin overlaps, reach and optimize efficiency of element, the space availability ratio of increase wiring board wiring and reduce the purpose of component size.

Detailed description of the invention
By inventive feature, technological means and the specific purposes reached, function can be further appreciated that, with detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 4 to 6, electromagnetic induction device of the present invention includes iron core 10, pedestal 20 and coil windings 30, described pedestal 20 is fixing with described iron core 10 to be connected, described pedestal 20 side offers holding hole (figure does not indicates), described holding hole fixing has pin set 40, described pin set 40 employing conductive copper material manufactures, and described pin set 40 is the slice of cylinder of semi-closed structure.
Described coil windings 30 uses multi cord twisted wire 31 to construct, described multi cord twisted wire 31 is provided with lead-foot-line 311, described multi cord twisted wire 31 is wound on pedestal 20, and described lead-foot-line 311 is fastened in described pin set 40, and described lead-foot-line 311 is fixed together by soldering with pin set 40.
When the present invention manufactures, first the lead-foot-line 311 of multi cord twisted wire 31 is fixed in pin set 40, then lead-foot-line 311 is carried out scolding tin, after scolding tin, lead-foot-line 311 is fixed together with pin set 40, now the lead-foot-line 311 of multi cord twisted wire 31 is because being gripped by pin set 40, and it is corresponding that lead-foot-line 311 exterior structure after scolding tin overlaps 40 exterior structure couplings with pin.
When the present invention uses, when multi cord twisted wire 31 inserts on external circuit plate, lead-foot-line 311 is under the effect that grips of pin set 40, again weld with external circuit plate, the lead-foot-line 311 that now loop current is directly over overlapping 40 couplings corresponding with pin flows on multi cord twisted wire 31, reduce electric current loss in conduction, optimize efficiency of element；Simultaneously, owing to pin overlaps 40 position-limiting actions to lead-foot-line 311, it is corresponding that lead-foot-line 311 exterior structure after scolding tin overlaps 40 exterior structure couplings with pin, only with offering the hole corresponding with pin set 40 coupling on external circuit plate, reduce the space loss that external circuit plate causes on pore space structure, add the space availability ratio of external circuit plate wiring；Utilize pin set 40 to be fixed spacing to lead-foot-line 311, utilize pin set 40 to combine with lead-foot-line 311 and substitute the terminal structure of traditional electromagnetic induction device, and then reduce element design size.
In sum, the electromagnetic induction device of the present invention pin set 40 by the conduction of clamping on pedestal 20, scolding tin is coordinated to be connected fixing with pin set 40 for the lead-foot-line 311 of multi cord twisted wire 31, utilize the fixing position-limiting action of pin set 40, reach and optimize efficiency of element, the space availability ratio of increase wiring board wiring and reduce the purpose of component size.
Embodiment described above only have expressed one embodiment of the present invention, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
