Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3, the present utility model provides a tri-inductor, which includes a base plate 100 and a magnetic core 200 mounted on the base plate 100, wherein three legs 201 are disposed in the magnetic core 200, the tri-inductor further includes three coils 300 respectively mounted on the three legs 201, the coils 300 include a winding portion 301 and two lead portions 302 led out from the winding portion 301, the winding portion 301 is wound on the legs 201, and the two lead portions 302 pass through the base plate 100.

Specifically, the magnetic core 200 includes two magnetic blocks that fit up and down, where the upright 201 is split into two parts and placed on the upper and lower two magnetic blocks respectively, when assembling, the two magnetic blocks are spliced and the two divided upright are recombined into a whole, the winding portions 301 of the three coils 300 are wound on the three upright 201 respectively, where the two sides of the magnetic core 200 are open, a part of the winding portions 301 is exposed to the outside, so that the coil has a sufficient heat dissipation area, the temperature of the whole product is reduced, six hole sites are provided on the bottom plate 100, the lead portions 302 are actually two ends of the coil 300 wound, and the two lead portions 302 pass through the corresponding two hole sites on the bottom plate 100 respectively, so as to facilitate subsequent assembling.

Further, the three-in-one inductor further comprises three first gaskets 400, the three first gaskets 400 are respectively sleeved on the three upright posts 201 correspondingly, the first gaskets 400 are insulated from the magnetic core 200, the three-in-one inductor further comprises two second gaskets 500, the two second gaskets 500 are respectively arranged on the inner wall of the magnetic core 200 and respectively correspond to the two ends of the winding part 301 to abut against, and the second gaskets 500 are insulated from the magnetic core 200.

Specifically, when the coil 300 is wound on the post, the magnetic core 200 separates the place where the coil 300 will contact the magnetic core 200 by the first and second shims 400 and 500, so that the coil 300 only contacts the first and second shims 400 and 500 in the magnetic core 200, wherein the first and second shims 400 and 500 are made of nomex paper, which is a synthetic aromatic amide polymer insulating paper, having high mechanical properties, flexibility and good electrical properties, and maintaining its characteristics at a high temperature.

Further, the upright 201 is formed by stacking a plurality of magnetic sheets 2011 and a plurality of third gaskets 2012, wherein the third gaskets 2012 comprise nomex paper.

Referring to fig. 2, the third gasket 2012 is an annular gasket and is stacked with the plurality of magnetic sheets 2011 in a staggered manner to form the upright column 201, and the process adopts a segmented air gap process, so that the thermal effect of the product is effectively reduced, and the thermal effect is uniformly dispersed, thereby reducing the loss of the magnetic core, improving the product efficiency, and simultaneously effectively reducing the leakage magnetic flux.

Further, the tri-element inductor further comprises two tin-permeable strips 600, the two tin-permeable strips 600 being mounted on the side of the base plate 100 remote from the magnetic core 200.

The foregoing is merely exemplary of the utility model, and it should be noted that modifications could be made by those skilled in the art without departing from the inventive concept, which fall within the scope of the utility model.
