The noise filter includes a core-holding section for holding a core, first and second cable-guiding sections, and two coupling sections coupling the first and second cable-guiding sections to ends of the core-holding section. The first and second cable-guiding section have truncated conical shape, and each divided into the four parts by a first to fourth slits arrayed in cruciform shape whose crossing position is coincident with an imaginary apex of the cable-guiding section. The coupling section has first to fourth circumferential elongated slots in communication with the proximal ends of the first to fourth slits.
BACKGROUND OF THE INVENTION The present invention relates to a noise filter including a case and a tubular core assembled therein.
SUMMARY OF THE INVENTION It is therefore, an object of the present invention to provide a noise filter provided with a case having a simplified construction and capable of holding the cable irrespective of cable diameter and number of cables of the bundle in case of looped setting.
FIG. 6 is a cross-sectional view of the noise filter taken along the line VI�VI of FIG. 1;
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A noise filter according to an embodiment of the present invention will be described with reference to FIGS. 1 through 7. FIG. 1 shows a noise filter 1 secured to a cable 100. As shown in FIG. 1, the noise filter 1 includes a case 2 and a core 3. The case 2 generally has a hollow cylindrical configuration and is made from resin provided with a resiliency. The core 3 is shaped like a hollow cylinder made from a magnetic substance and has a through hole allowing the cable 100 to pass therethrough.
As shown in FIG. 2, the first cable-guiding section 5 shaped like a truncated cone is divided into four parts 51, 52, 53 and 54, which are sectioned by four slits 51 a, 52 a, 53 a and 54 a and sequentially arranged in the circumferential direction of the first cable-guiding section 5. In the y-z cross-section, the first cable-guiding section 5 is divided into the four parts, 51, 52, 53, 54 by the slits 51 a, 52 a, 53 a and 54 a those arranged in a cruciform fashion whose crossing center is coincident with an imaginary apex of the truncated cone. The first cable-guiding section 5 has an opening 5 a in its distal end. The opening 5 a has an inner diameter smaller than the outer diameter of the cable 100 prior to setting the noise filter 1 over the cable 100. Further, parting faces of the first case 21 and the second case 22 are in alignment with and within width of the first slit 51 a and the third slit 53 a. Thus, the first and second parts 51 and 52 belong to the first case 21, and the third and fourth parts 53 and 54 belong to the second case 22. In other words, it is unnecessary to positively form a slit between first part 51 and the fourth part 54, and between the second part 52 and the third part 53, since the parting faces of the firs and second cases 21 and 22 can function as slits. Further, the cruciform arrangement of the slits can provide substantially equal shape among these parts 51 through 54. Therefore, these parts 51�54 can provide uniform and symmetrical pressure to the cable 100.
