Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure sectional view of the utility model middle graph.
Specific embodiment
It is described further referring to figs. 1 to Fig. 2 embodiments of the present utility model.
A kind of magnetic core with low loss, including core body 1 and the upper bar body 2 with the connection of core body 1, lower bar body 4 and centre
Body 3, intermediate 3 is placed between bar body 2 and lower bar body 4, and the magnetic core with low loss is integral type structure.
Real core body is provided with the inner core-body 32 that intermediate 3 includes external core 31 and is placed in external core 31, inner core-body 32
33, the inwall of external core 31 is provided with some locating slots, and those locating slots are in wave wire, and the outer wall of inner core-body 32 is provided with use
In the positioning convex 3a being adapted to locating slot, external core 31 includes outer entity portion 311 and outer space center portion 312, and inner core-body 32 is placed in
In outer space center portion 312, inner core-body 32 includes interior entity portion 321 and interior hollow part 322, and real core body 33 is placed in interior hollow part 322.
Intermediate 3 uses 31 sets of inner core-bodies 32 of external core, 32 sets of real core bodys 33 of inner core-body increasing the feelings of core volume
Under condition, the magnetic intensity of magnetic core is increased, inner core-body 32 and real core body 33 can produce a magnetic force respectively, after two magnetic force superpositions
The magnetic force with external core 31 is superimposed again, and then greatly improves the magnetic force of power magnetic core, and then improves the service life of magnetic core
In said structure, in order to further improve magnetic intensity, so be provided with inner core-body 32 determine positioning convex 3a,
External core 31 is provided with the locating slot for installing spacing positioning convex 3a.It is in wave wire that locating slot is set, and improves inner core
The connective stability and bonding strength of body 32 and external core 31, and wave structure relative rectilinear, improve positioning convex
The path length of 3a, and then improve magnetic intensity.
Intermediate 3 causes to coordinate more stable between all parts in intermediate 3 for integral type structure, and intermediate
3 Stability Analysis of Structures of itself.
