A base, base outer wall top through lug fixed connection be equipped with the stitch, the base top has a draw -in groove, draw -in groove position and stitch position looks adaptation that is used for common mode inductance's base, including the cylinder . the utility model discloses convenient assembling, stitch non -deformable, further preferred adoption amorphous magnetic core for the finished product volume of producing is less, and the temperature rise is lower, has improved efficiency.
Description
Technical field
The utility model relates to a kind of common mode inductance and a kind of pedestal for common mode inductance.
Background technology
In the dynamo-electric source plate design of TV, the normal electromagnetic interference signal using common mode inductance filtering common mode.During current common mode inductance is manufactured, the normal ferrite that uses is as magnetic core, and because the magnetic permeability of Ferrite Material own is low, temperature characterisitic is poor, the common mode inductance made, volume is comparatively large, and temperature rise is higher, efficiency is lower, and it is loaded down with trivial details to there is the course of processing, the yielding problem of stitch.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of easy to assembly, on-deformable common mode inductance of stitch.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: common mode inductance, comprise the magnetic core of annular, magnetic core is arranged with symmetrically arranged first coil, the second coil, magnetic core is located in columnar pedestal, base outer wall top is provided with stitch with being fixedly connected with by projection, pedestal top has draw-in groove, and the two ends of the first coil, the two ends of the second coil all have terminals, are connected after terminals pile warp draw-in groove with stitch.
Further: terminals are fixed by zinc-plated after being wound on stitch.
Further: magnetic core is amorphous magnetic core.
Further: be provided with dividing plate perpendicular to its bottom surface in pedestal, dividing plate passes from the middle part of magnetic core, the first coil, the second coil is separated.
Correspondingly, another technical problem to be solved in the utility model is: provide a kind of easy to assembly, on-deformable pedestal for common mode inductance of stitch.
The technical scheme adopted for solving this technical problem the utility model is: for the pedestal of common mode inductance, comprise columnar pedestal, base outer wall top is provided with stitch with being fixedly connected with by projection, and pedestal top has draw-in groove, draw-in groove position and stitch position suitable.
Further: in pedestal, be provided with dividing plate perpendicular to its bottom surface.
The beneficial effects of the utility model are: assemble magnetic core by arranging columnar pedestal, stitch is fixedly installed by projection, and stitch itself has higher intensity, and draw-in groove plays the role of positioning.The utility model is easy to assembly, stitch is not yielding, preferably adopts amorphous magnetic core further, and make the finished-product volume produced less, temperature rise is lower, improves efficiency.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, common mode inductance, comprise the magnetic core 1 of annular, magnetic core 1 is arranged with symmetrically arranged first coil 11, second coil 12, magnetic core 1 is located in columnar pedestal 2, and pedestal 2 outer wall top is provided with stitch 3 with being fixedly connected with by projection 21, and pedestal 2 top has draw-in groove 22, the two ends of the first coil 11, the two ends of the second coil 12 all have terminals 13, are connected after terminals 13 pile warp draw-in groove 22 with stitch 3.Draw-in groove 22 position should be suitable with stitch 3 position, terminals 13 position, and usual draw-in groove 22 is located on projection 21.For convenience of assembling, the rectangular distribution in position of four corresponding stitch of terminals 13 difference, 3, four stitch 3.
Particularly, can adopt and weld between terminals 13 with stitch 3, preferred implementation is, adopts terminals 13 to be wound on stitch 3 afterwards by zinc-plated fixing, easy to assembly.
As to improvement of the present utility model, magnetic core 1 preferably adopts amorphous magnetic core, and make the finished-product volume produced less, temperature rise is lower, improves efficiency.
Preferably, be provided with dividing plate 23 perpendicular to its bottom surface in pedestal 2, dividing plate 23 passes from the middle part of magnetic core 1, is separated by the first coil 11, second coil 12.
For the pedestal for common mode inductance, the technical scheme of employing is, comprises columnar pedestal 2, and pedestal 2 outer wall top is provided with stitch 3 with being fixedly connected with by projection 21, and pedestal 2 top has draw-in groove 22, draw-in groove 22 position and stitch 3 position suitable.Preferably, dividing plate 23 is provided with perpendicular to its bottom surface in pedestal 2.
