Abstract
The utility model belongs to the technical field of electromagnetism, and relates to a round jar-shaped magnetic core with a cover, which mainly comprises the round jar-shaped magnetic core; and the middle part of the magnetic core is provided with a central post and a middle through hole, and the round jar-shaped magnetic core has the characteristics that a movable cover with the size and the shape consistent with those of the upper surface of the magnetic core is arranged on the upper end of the round jar-shaped magnetic core, and a middle through hole corresponding to the middle through hole of the magnetic core, and a small hole for leads are arranged in the movable cover. According to the round jar-shaped magnetic core with the cover, the effect on magnetic shielding due to the leads on two sides of the round jar-shaped magnetic core can be overcome, and the shielding effect is better.
Description
Technical field: the utility model belongs to electromagnetic technology field, is specifically related to a kind of improved jar of type magnetic core, and promptly round can is added a cover the type magnetic core.
Background technology: along with the development of electromagnetic compatibility work, electromangnetic spectrum is more and more widely used.The jar type magnetic core that is pressed into ferrite also is used as low frequency magnetic screen or electromagnetic shielding.
With regard to difform magnetic core, each is variant for its shield effectiveness, compares, and jar type is more better.Magnetic core shield effectiveness commonly used at present sees the following form
But a jar type magnetic core all has the lead-out wire groove on the both sides of symmetry, and still shield effectiveness is undesirable near groove.At some magnetic screen is required can not meet the demands in the stricter device.
Summary of the invention: the purpose of the utility model is to provide the better round can of a kind of shielding properties to add a cover the type magnetic core to the weak point of existing magnetic core.
The utility model overcomes the influence of jar type magnetic core both sides lead-in wire groove to magnetic screen, and shielding properties is better.
To achieve these goals; The main technical schemes of the utility model is: comprise round can type magnetic core; There are newel and middle through hole in the magnetic core middle part; It is characterized in that being provided with and the corresponding to removable cover of magnetic core upper surface size shape in the upper end of round can type magnetic core, have on the removable cover with magnetic core in the corresponding middle through hole of through hole and the aperture that is used to go between.
The utility model complete closed the lead-in wire groove of existing jar type magnetic core both sides; The upper end face of magnetic core increase by one with the identical removable cover of magnetic core upper surface size shape, have the usefulness that a lead-in wire aperture is made lead-in wire covering, fairlead is littler much than the jar type; Magnetic core and removable cover are used during use; Coil is on the core center post, and lead-in wire is drawn from removable cover lead-in wire aperture, covers removable cover; So in use coil can be enclosed among the magnetic core, than existing jar of type magnetic core better shield effectiveness is arranged.
Description of drawings: accompanying drawing 1 is the utility model embodiment core structure sketch map; Fig. 2 is the structural representation of present embodiment magnetic core removable cover.
Among the figure, 1-round can magnetic core tank body; 2-core center post; Through hole among the 3-; The 4-removable cover; The 5-aperture that goes between.
Embodiment: the utility model is described in detail below in conjunction with embodiment and accompanying drawing.
Embodiment
Present embodiment mainly comprises round can type magnetic core tank body 1 shown in accompanying drawing 1, there are newel 2 and middle through hole 3 in magnetic core tank body 1 middle part, is provided with and the corresponding to removable cover 4 of magnetic core upper surface size shape in the upper end of round can type magnetic core tank body 1; The structure of removable cover 4 shown in accompanying drawing 2, have on the removable cover 4 with magnetic core in the corresponding middle through hole 3 of through hole 3 and the aperture 5 that is used to go between.
The present embodiment complete closed lead-in wire groove of existing jar type magnetic core both sides; Upper end face at magnetic core increases a removable cover 4 identical with magnetic core upper surface size shape, on removable cover 4, has the usefulness that a lead-in wire aperture 5 is made lead-in wire, and fairlead 5 is littler much than jar type; Magnetic core and removable cover 4 are used during use; Coil is on core center post 2, and lead-in wire is drawn from removable cover 4 lead-in wire apertures 5, covers removable cover 4; So in use coil can be enclosed among the magnetic core, than existing round can type magnetic core better shield effectiveness is arranged.
