本発明はケーブルに関し、特にシールドケーブルの構造
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to cables, and particularly to the structure of shielded cables.
従来、この種のシールドケーブルは第２図のように内部
導体１１から発生する輻射ノイズをシールド導体１４に
よって内部に反射し、ケーブルの外部へ漏れないように
している。１２は絶縁体、１３は抑え巻、１５は外被で
ある。Conventionally, in this type of shielded cable, as shown in FIG. 2, radiated noise generated from an internal conductor 11 is reflected inward by a shielded conductor 14 to prevent it from leaking to the outside of the cable. 12 is an insulator, 13 is a restraining winding, and 15 is an outer cover.
上述した従来のシールドケーブルはシールド層が導体の
みで形成されているので、内部導体１１から漏れた電流
がシールド導体１４を流れ、シールド導体Ｌ４から外部
へノイズを輻射し、これが外乱を引き起こす原因になる
という欠点がある。In the conventional shielded cable described above, the shield layer is formed only of a conductor, so the current leaking from the internal conductor 11 flows through the shield conductor 14 and radiates noise from the shield conductor L4 to the outside, which causes disturbance. It has the disadvantage of becoming.
本発明の目的はシールド導体から発するノイズの誦洩を
防止するシールドケーブルを提供することにある。An object of the present invention is to provide a shielded cable that prevents noise emitted from a shielded conductor from leaking.
、 本発明のシールドケーブルはシールド導体にフェ
ライトの粉末を塗布したことを特徴とするものである。The shielded cable of the present invention is characterized in that the shielded conductor is coated with ferrite powder.
次に、本発明の一実施例について図面を参照して説明す
る。Next, an embodiment of the present invention will be described with reference to the drawings.
第１図は本発明の一実施例の断面図である。本実施例で

れている。FIG. 1 is a sectional view of an embodiment of the present invention. In this embodiment, a four-core cable is used as an example. Internal conductor 1 is insulator 2
is insulated from other internal conductors and fixed by a restraining winding 3. A shield conductor 4 coated with ferrite powder 5 is wound on the restraining winding 3, and the outside thereof is covered with a jacket 6.

内部導体１からシールド導体４に漏れる電流はフェライ
ト粉末５の磁気作用により小さくなり、シールド導体４
からの輻射ノイズが小さくなる。Therefore, the radiation noise generated in the internal conductor 1 is reflected internally by the shield conductor 4 and does not leak to the outside. Also,
The current leaking from the internal conductor 1 to the shield conductor 4 becomes smaller due to the magnetic effect of the ferrite powder 5,
The radiated noise from the

イズを低減できる効果がある。As explained above, the present invention has the effect of reducing noise generated from the shield conductor by applying ferrite powder to the shield conductor.
第１図は本発明のシールドケーブルの一実施例の断面図
、第２図は従来のシールドケーブルの断面図である。FIG. 1 is a sectional view of an embodiment of the shielded cable of the present invention, and FIG. 2 is a sectional view of a conventional shielded cable.
