Embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reach, function, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As extremely shown in Figure 6 in Fig. 4, the utility model electromagnetic induction device 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 is the conduction copper sheathing, 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 pedestal 20, described lead-foot-line 311 is fastened in described pin cover 40, and described lead-foot-line 311 is fixed together by soldering with pin cover 40.
When the utility model is made, at first the lead-foot-line 311 with multi cord twisted wire 31 is fixed in pin cover 40, then lead-foot-line 311 is carried out scolding tin, after scolding tin, lead-foot-line 311 is fixed together with pin cover 40, 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 after scolding tin are corresponding with pin cover 40 exterior structures couplings.
When the utility model 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 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, position-limiting action due to 40 pairs of lead-foot-lines 311 of pin cover, lead-foot-line 311 exterior structures after scolding tin are corresponding with pin cover 40 exterior structure couplings, only mate corresponding hole with offering with pin cover 40 on the external circuit plate, reduce the space loss that the external circuit plate causes on pore space structure, increased the space availability ratio of external circuit plate wiring; Utilize 40 pairs of lead-foot-lines 311 of pin cover to be fixed spacing, utilize pin cover 40 to combine with lead-foot-line 311 to substitute the terminal structure of traditional electrical magnetic-inductive device, and then dwindle the element design size.
In sum, the utility model electromagnetic induction device is by holding the pin cover 40 of conduction on pedestal 20, coordinate 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.
