Patent US 7,173,182 B2
a closed magnetic path core which is fitted on a separated part of said insulating coating layer at the end of said shielded cable, wherein and end of said shielding layer is folded back and fully covers and directly contacts outside of said closed magnetic path core so as to form a coil of one turn, an insulating tape is wound around said shielding layer in a peripheral portion of said closed magnetic path core, and a tip portion of said shielding layer is connected to said shielding metal cover in a state where said closed magnetic path core is housed in said shielding metal cover.

As shown in an enlarged view in FIG. 3, a tip of the braided shield 16 is spread out, folded back all around so as to entirely cover the outside of the toroidal core 22, and extended to the insulating coating layer 20 (a folded part of the braided shield is indicated by reference numeral 16a). Thereafter, a metal tape 24 is wound around an end 16b of the braided shield 16, which is laid on the insulating coating layer 20, to fix the end 16b. Moreover, an insulating tape 26 is wound around the folded part 16a of the braided shield 16, which is positioned on an outer circumferential surface of the toroidal core 22.
A tip core wire part 14a of each of the insulated wires 14 is connected to each of corresponding terminals 32 in a housing part 30. Thereafter, a shielding metal cover 34 extending from the housing part 30 to a cable end is electrically and mechanically connected by use of, for example, a method such as “caulking” so as to allow its rear end to come into contact with the metal tape 24. Lastly, at least a base side of the shielding metal cover 34 is resin-molded (indicated by reference numeral 36).
Since the configuration of the present invention includes the toroidal core 22, there is a possibility of the folded part 16a of the braided shield 16 rising. If, in connection and assembly of the connector and the cable, the shielding metal cover 34 and the folded part 16a of the braided shield come into electrical contact with each other in the connector, there is a possibility that the number of turns, that is, one turn of the toroidal core 22 can no longer be realized. Accordingly, in the present invention, the insulating tape 26 is wound around the braided shield folded part 16a covering the toroidal core 22 to secure electrical insulation between the shielding metal cover 34 and the folded part 16a of the braided shield. Thus, formation of the one-turn coil is guaranteed.
