Background technology
At present, electromagnetic induction device such as transformer are the electronic building brick that often uses in the various electric equipment, the large scale electrical equipment such as the LCD TV that have develop towards large scale, large scale needs large power, large power needs the thick wire rod of usage comparison, and the frequency of circuit working is higher, so adopt the multi cord line to be twisted into the mode of thick line more.
As shown in Figure 1, traditional electrical magnetic-inductive device structure mainly comprises iron core group 10 ' and coil windings 20 ', and coil windings adopts the multi cord twisted wire to be wrapped in the 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 fixture, when it inserts on the wiring board, can have the problem of pin contracting, causes the bad phenomenon of scolding tin behind the wave-soldering; In addition, behind the lead-foot-line scolding tin of multi cord twisted wire, it is irregularly shaped that outward appearance can be, for satisfying the different lead-foot-line specifications behind the scolding tin, the hole on the wiring board must reach greatly, and lead-foot-line could insert smoothly, the wiring space meeting scaled-back of wiring board like this, after wiring board passed through wave-soldering, need to carry out the repair welding operation, avoid producing tin hole problem.
As shown in Figures 2 and 3, the lead-foot-line of existing multi cord twisted wire was fixed on the terminal 30 ' of electromagnetic induction device when upper, or was arranged on the electromagnetic induction device both sides, caused the electromagnetic induction device planar dimension to increase; Or be arranged on top or the bottom of electromagnetic induction device, cause the electromagnetic induction device height to increase; In addition, when the lead-foot-line of multi cord twisted wire was fixed on the terminal, loop current will through on the terminal ability runner multi cord twisted wire, can produce unnecessary conduction loss at terminal.
Summary of the invention
Based on this, be necessary the problem for the existence of above-mentioned background technology, provide a kind of and optimize efficiency of element, increase the space availability ratio of wiring board wiring and dwindle the electromagnetic induction device of component size.
For achieving the above object, the invention discloses a kind of electromagnetic induction device, it comprises iron core, pedestal and coil windings, described pedestal is fixedly connected with described iron core, fixing has the pin cover on the described pedestal, and described coil windings adopts multi cord twisted wire structure, and described multi cord twisted wire is provided with lead-foot-line, described multi cord twisted wire is wound on the pedestal, and described lead-foot-line is fastened in the described pin cover.
Among embodiment, described pedestal one side offers holding hole therein, and described pin cover is immobilizated in the holding hole.
Among embodiment, described pin cover adopts the conductive material manufacturing therein.
Among embodiment, described pin cover adopts the copper material manufacturing therein.
Among embodiment, described pin cover is the cylinder sheet therein.
Among embodiment, described pin cover is semi-closed structure therein.
Among embodiment, described lead-foot-line and pin cover are fixed together by soldering therein.
In sum, electromagnetic induction device of the present invention is by holding the pin cover of conduction at pedestal, cooperate scolding tin that the lead-foot-line of multi cord twisted wire is fixedly connected with the pin cover, utilize the fixedly position-limiting action of pin cover, reach the space availability ratio of optimizing efficiency of element, the wiring of increase wiring board and the purpose of dwindling component size.

Embodiment
For further understanding feature of the present invention, technological means and the specific purposes that reach, function, below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
Extremely shown in Figure 6 such as Fig. 4, electromagnetic induction device of the present invention comprises iron core 10, pedestal 20 and coil windings 30, described pedestal 20 is fixedly connected with described iron core 10, described pedestal 20 1 sides offer holding hole (figure does not indicate), described holding hole fixing has pin cover 40, described pin cover 40 adopts the manufacturing of conductive copper material, and described pin cover 40 is the slice of cylinder of semi-closed structure.
Described coil windings 30 adopts multi cord twisted wire 31 structures, described multi cord twisted wire 31 is provided with lead-foot-line 311, described multi cord twisted wire 31 is wound on the pedestal 20, described lead-foot-line 311 is fastened in the described pin cover 40, and described lead-foot-line 311 and pin cover 40 are fixed together by soldering.
When the present invention makes, at first the lead-foot-line 311 with multi cord twisted wire 31 is fixed in the pin cover 40, then lead-foot-line 311 is carried out scolding tin, lead-foot-line 311 is fixed together with pin cover 40 behind the scolding tin, the lead-foot-line 311 of multi cord twisted wire 31 is because being gripped by pin cover 40 at this moment, and lead-foot-line 311 exterior structures behind the scolding tin overlap 40 exterior structures with pin and mate corresponding.
When the present invention uses, when multi cord twisted wire 31 inserts on the external circuit plate, lead-foot-line 311 is under the effect that grips of pin cover 40, again weld with the external circuit plate, this moment, loop current directly flowed on the multi cord twisted wire 31 through the lead-foot-line 311 corresponding with pin cover 40 couplings, reduce the loss of electric current in conduction, optimized efficiency of element; Simultaneously, because the position-limiting action of 40 pairs of lead-foot-lines 311 of pin cover, lead-foot-line 311 exterior structures behind the scolding tin overlap 40 exterior structures with pin and mate corresponding, only mate corresponding hole with offering with pin cover 40 on the external circuit plate, reduce the external circuit plate at the space loss that pore space structure causes, increased the space availability ratio of external circuit plate wiring; It is spacing to utilize 40 pairs of lead-foot-lines 311 of pin cover to be fixed, and utilizes pin cover 40 to combine to substitute the terminal structure of traditional electrical magnetic-inductive device with lead-foot-line 311, and then dwindles the element design size.
In sum, electromagnetic induction device of the present invention is by holding the pin cover 40 of conduction at pedestal 20, cooperate scolding tin that the lead-foot-line 311 of multi cord twisted wire 31 is fixedly connected with pin cover 40, utilize the fixedly position-limiting action of pin cover 40, reach the space availability ratio of optimizing efficiency of element, the wiring of increase wiring board and the purpose of dwindling component size.
