Description

本発明は、ノイズ抑制ケーブルに関する。   The present invention relates to a noise suppression cable.

近年、データ密度の高い信号を伝送するためにケーブルが伝送する信号の周波数が増加している。ケーブルが伝送する信号の周波数が増加することにより、ケーブルから放射ノイズ及びケーブルのシールド層を伝わる伝導ノイズが強く発生することから、ケーブルには、放射ノイズ及び伝導ノイズを抑制することが求められている。   In recent years, in order to transmit signals with high data density, the frequency of signals transmitted by cables has increased. As the frequency of the signal transmitted by the cable increases, radiation noise and conduction noise transmitted through the shield layer of the cable are strongly generated. Therefore, the cable is required to suppress radiation noise and conduction noise. Yes.

従来、芯線と、芯線の外側に設けられた第1の絶縁層と、第1の絶縁層の外側に設けられたシールド層と、シールド層の外側に設けられた第2の絶縁層と、第2の絶縁層の外側に形成されたアモルファス磁性体層とを備え、アモルファス磁性体層に誘導電流を発生させることにより放射ノイズ及び伝導ノイズを抑制したシールドケーブルが提案されている(例えば、特許文献1参照。)。   Conventionally, a core wire, a first insulating layer provided outside the core wire, a shield layer provided outside the first insulating layer, a second insulating layer provided outside the shield layer, And a shielded cable that suppresses radiation noise and conduction noise by generating an induced current in the amorphous magnetic layer (see, for example, Patent Documents). 1).

特開2002−157924号公報JP 2002-157924 A

しかし、特許文献1に記載のシールドケーブルでは、アモルファス磁性体層に発生した誘導電流により放射ノイズ及び伝導ノイズが発生することから、シールドケーブルが伝送する信号の周波数が増加した場合には、放射ノイズ及び伝導ノイズを抑制する効果が小さくなるという問題がある。   However, in the shielded cable described in Patent Document 1, radiation noise and conduction noise are generated by the induced current generated in the amorphous magnetic layer. Therefore, when the frequency of the signal transmitted by the shield cable increases, radiation noise is generated. In addition, there is a problem that the effect of suppressing conduction noise is reduced.

そのため、本発明の目的は、伝送する信号の周波数が増大しても放射ノイズ及び伝導ノイズを抑制することができるノイズ抑制ケーブルを提供することにある。   Therefore, an object of the present invention is to provide a noise suppression cable that can suppress radiation noise and conduction noise even when the frequency of a signal to be transmitted increases.

A magnetic member having a belt-like or linear shape to be wound, the magnetic member having a conversion portion that is wound around the support wire and changes a winding direction, and the magnetic member is adjacent to the periphery of the insulated wire And a magnetic member layer formed so that the winding direction is reversed.

前記磁性部材は、磁性体層と前記磁性体層を挟むように形成された1対の絶縁体層とを有する帯状の形状を有し、前記磁性部材層は、前記磁性部材の前記絶縁体層同士が一部重なるように、前記磁性部材が前記絶縁電線に巻きつけられて形成されるのが好ましい。また、前記磁性部材層は、隣接する前記磁性部材との間に間隔が設けられるように、前記磁性部材が前記絶縁電線に巻き付けられて形成されてもよい。   The magnetic member has a band shape having a magnetic layer and a pair of insulator layers formed so as to sandwich the magnetic layer, and the magnetic member layer is the insulator layer of the magnetic member. It is preferable that the magnetic member is formed by being wound around the insulated wire so that they partially overlap each other. Further, the magnetic member layer may be formed by winding the magnetic member around the insulated wire so that a gap is provided between the adjacent magnetic members.

また、前記絶縁電線は、前記絶縁体の周囲に形成された外部導体層と、前記外部導体層の周囲に形成された絶縁部材層をさらに有し、前記磁性部材層は、前記絶縁部材層の周囲に巻き付けられるのが好ましい。   The insulated wire further includes an outer conductor layer formed around the insulator and an insulating member layer formed around the outer conductor layer, and the magnetic member layer is formed of the insulating member layer. Preferably it is wrapped around.

The magnetic tape 60 has a belt-like shape and is wound around the resin tape layer 5 and the support wire 7 with an interval so as not to overlap each other. The magnetic tape 60 is an example of a magnetic member.

(磁性体テープ層の形成方法)
次に、磁性体テープ層6の形成方法の一例について説明する。
(Method for forming magnetic tape layer)
Next, an example of a method for forming the magnetic tape layer 6 will be described.

内部導体2の周囲に絶縁層3、外部導体層4及び樹脂テープ層5を形成し、樹脂テープ層5と支持線7とを所定の間隔を設けて配置する。   An insulating layer 3, an outer conductor layer 4 and a resin tape layer 5 are formed around the inner conductor 2, and the resin tape layer 5 and the support wire 7 are arranged at a predetermined interval.

次に、磁性体テープ60を図4に示すa点からb点に向かって樹脂テープ層5の周囲に図4における時計回りに巻き付け、磁性体テープ60を樹脂テープ層5と支持線7との間(図4に示すb点)を通過させる。   Next, the magnetic tape 60 is wound around the resin tape layer 5 in the clockwise direction in FIG. 4 from the point a to the point b shown in FIG. 4, and the magnetic tape 60 is placed between the resin tape layer 5 and the support wire 7. The interval (point b shown in FIG. 4) is passed.

次に、磁性体テープ60を図4に示すb点からc点を経由し、d点に向かって樹脂テープ層5及び支持線7の周囲に図4における反時計回りに巻き付ける。   Next, the magnetic tape 60 is wound around the resin tape layer 5 and the support wire 7 counterclockwise in FIG. 4 from the point b to the point c shown in FIG.

このとき、支持線7を樹脂テープ層5に対して磁性体テープ60の幅と磁性体テープ60間の間隔とを加算した距離だけ磁性体テープ60を巻き付ける方向(図3に示すB方向)に進行させる。   At this time, the magnetic tape 60 is wound around the support wire 7 by a distance obtained by adding the width of the magnetic tape 60 and the interval between the magnetic tapes 60 to the resin tape layer 5 (direction B shown in FIG. 3). Make it progress.

次に、磁性体テープ60を図4に示すd点からb点に向かって樹脂テープ層5の周囲に反時計回りに巻き付け、磁性体テープ60を樹脂テープ層5と支持線7との間(図4に示すb点)を通過させる。   Next, the magnetic tape 60 is wound counterclockwise around the resin tape layer 5 from the point d to the point b shown in FIG. 4, and the magnetic tape 60 is placed between the resin tape layer 5 and the support wire 7 ( The point b shown in FIG. 4 is passed.

次に、磁性体テープ60を図4に示すb点からc点を経由し、e点に向かって樹脂テープ層5及び支持線7の周囲に図4における時計回りに巻き付ける。   Next, the magnetic tape 60 is wound around the resin tape layer 5 and the support line 7 in the clockwise direction in FIG. 4 from the point b to the point c shown in FIG.

以上の工程を1サイクルとし、このサイクルを繰り返して磁性体テープ60を樹脂テープ層5及び支持線7の周囲に磁性体テープ60同士が重ならないように巻き付ける。   The above process is defined as one cycle, and this cycle is repeated to wind the magnetic tape 60 around the resin tape layer 5 and the support wire 7 so that the magnetic tapes 60 do not overlap each other.

(ノイズ抑制ケーブルの作用)
次に、ノイズ抑制ケーブル1の作用について図4を用いて説明する。
(Operation of noise suppression cable)
Next, the effect | action of the noise suppression cable 1 is demonstrated using FIG.

内部導体2が特定の周波数を有する信号を伝送すると、内部導体2から発生する磁束によって磁性体テープ60に誘導電流Iが誘起される。 When the internal conductor 2 transmits a signal having a specific frequency, an induced current I 1 is induced in the magnetic tape 60 by the magnetic flux generated from the internal conductor 2.

例えば、a点から発生した誘導電流Iが図4に示すb点及びc点を経由してd点に到達した以降の電流を誘導電流Iとすると、誘導電流I及び誘導電流Iが流れる方向は、図4に示すa点、d点及びe点間で逆向きになり、b点及びc点において逆向きになる。また、誘導電流I及び誘導電流Iは、それぞれ樹脂テープ層5の図4における側方において流れる方向が逆向きになる。 For example, assuming that the induced current I 1 generated from the point a reaches the point d via the points b and c shown in FIG. 4 as the induced current I 2 , the induced current I 1 and the induced current I 2. The direction in which the air flows is opposite between the points a, d and e shown in FIG. 4, and is opposite at the points b and c. In addition, the induced current I 1 and the induced current I 2 flow in opposite directions on the sides of the resin tape layer 5 in FIG.

誘導電流I及び誘導電流Iは、隣接する磁性体テープ60間で流れる電流の方向が逆になることから、隣接する磁性体テープ60間で逆向きの磁束を発生させ、互いに磁束を打ち消しあう。これにより、放射ノイズ及び伝導ノイズが抑制される。 The induced current I 1 and the induced current I 2 generate opposite magnetic fluxes between the adjacent magnetic tapes 60 since the directions of the currents flowing between the adjacent magnetic tapes 60 are reversed. meet. Thereby, radiation noise and conduction noise are suppressed.

(第1の実施の形態の効果)
本実施の形態によれば、以下の効果を奏する。
(1)隣接する磁性体テープ60同士の巻き付け方向が逆向きになるように、樹脂テープ層5及び支持線7の周囲に巻き付けることにより、磁性体テープ60に発生する誘導電流に基づく磁束を打ち消すことができる。そのため、磁性体テープ60に発生する誘導電流に基づく放射ノイズ及び伝導ノイズを抑制することが可能になる。
(2)磁性体テープ層6が誘導電流に基づく磁束を打ち消しあうことから、内部導体2が伝送する信号の周波数の増加により誘導電流が増大しても、放射ノイズ及び伝導ノイズを抑制することができる。
(Effects of the first embodiment)
According to the present embodiment, the following effects can be obtained.
(1) By winding around the resin tape layer 5 and the support wire 7 so that the winding directions of the adjacent magnetic tapes 60 are opposite to each other, the magnetic flux based on the induced current generated in the magnetic tape 60 is canceled out. be able to. Therefore, radiation noise and conduction noise based on the induced current generated in the magnetic tape 60 can be suppressed.
(2) Since the magnetic tape layer 6 cancels out the magnetic flux based on the induced current, even if the induced current increases due to an increase in the frequency of the signal transmitted by the internal conductor 2, radiation noise and conduction noise can be suppressed. it can.

[第2の実施の形態]
図5は、本発明の第2の実施の形態に係る磁性体テープ60の巻き付け方法を示す斜視図である。
[Second Embodiment]
FIG. 5 is a perspective view showing a winding method of the magnetic tape 60 according to the second embodiment of the present invention.

第1の実施の形態では、磁性体テープ60を互いに重ならないように樹脂テープ層5及び支持線7の周囲に巻き付けたが、本実施の形態では、磁性体テープ60は、樹脂層61を有するものを用い、一部が重なるように巻き付けられている点で異なる。以下、第1の実施の形態と異なる点を中心に説明する。   In the first embodiment, the magnetic tape 60 is wound around the resin tape layer 5 and the support wire 7 so as not to overlap each other. However, in this embodiment, the magnetic tape 60 includes the resin layer 61. It differs in that it is wound so that a part overlaps. The following description will focus on differences from the first embodiment.

本実施の形態のノイズ抑制ケーブル1の磁性体テープ60は、磁性体層61と、磁性体層61を挟むように形成された1対の樹脂層62とを備える。磁性体テープ60の樹脂層62は、磁性体テープ60の磁性体層61間を絶縁する。樹脂層62は、例えば、ポリエチレンテレフタレート(PET)、ポリプロピレン系樹脂等の樹脂から形成される。磁性体層61は、軟磁性金属等の磁性体から形成される。磁性体層61と1対の樹脂層62は、例えば接着剤や熱融着により接合される。なお、樹脂層62は、絶縁体層の一例である。   The magnetic tape 60 of the noise suppression cable 1 of this embodiment includes a magnetic layer 61 and a pair of resin layers 62 formed so as to sandwich the magnetic layer 61. The resin layer 62 of the magnetic tape 60 insulates between the magnetic layers 61 of the magnetic tape 60. The resin layer 62 is made of a resin such as polyethylene terephthalate (PET) or polypropylene resin. The magnetic layer 61 is made of a magnetic material such as soft magnetic metal. The magnetic layer 61 and the pair of resin layers 62 are bonded together by, for example, an adhesive or heat fusion. The resin layer 62 is an example of an insulator layer.

磁性体テープ60の巻き付け方法は、図4に示すのと同様である。磁性体テープ60が重なる領域では樹脂層62同士が接触する。   The winding method of the magnetic tape 60 is the same as that shown in FIG. In the region where the magnetic tape 60 overlaps, the resin layers 62 are in contact with each other.

磁性体テープ60の磁性体層61には、内部導体2に流れる信号に基づいて、隣接する磁性体テープ60の磁性体層61と逆方向の誘導電流が誘起される。磁性体層61は、誘起された誘導電流により互いに逆向きに磁束を発生させて磁束を打ち消す。   In the magnetic layer 61 of the magnetic tape 60, an induced current in the opposite direction to the magnetic layer 61 of the adjacent magnetic tape 60 is induced based on a signal flowing through the inner conductor 2. The magnetic layer 61 cancels the magnetic flux by generating magnetic fluxes in opposite directions with the induced current induced.

(第2の実施の形態の効果)
本実施の形態によれば、磁性体テープ60に磁性体層61を挟むように1対の樹脂層62を設けることにより隣接する磁性体テープ60間の距離を近くできるので、より効果的に磁性体テープ60に発生する誘導電流に基づく磁束を打ち消すことができる。そのため、放射ノイズ及び伝導ノイズをより抑制することが可能になる。なお、本実施の形態においては、指示線7に金属線を用いてもよい。
(Effect of the second embodiment)
According to the present embodiment, by providing the pair of resin layers 62 so that the magnetic layer 61 is sandwiched between the magnetic tapes 60, the distance between the adjacent magnetic tapes 60 can be reduced, so that the magnetic tape can be more effectively magnetically separated. The magnetic flux based on the induced current generated in the body tape 60 can be canceled out. Therefore, radiation noise and conduction noise can be further suppressed. In the present embodiment, a metal wire may be used for the instruction line 7.

[変形例]
本発明の実施の形態は、上記各実施の形態に限定されるものではなく、本発明の要旨を変更しない範囲内で種々に変形、実施が可能である。支持線7を樹脂テープ層5の周囲に2つ以上設け、隣接する磁性体テープ60同士の巻き付け方向が互いに逆向きになるように磁性体テープ60を樹脂テープ層5及び複数の支持線7に巻き付けてもよい。
[Modification]
Embodiments of the present invention are not limited to the above-described embodiments, and various modifications and implementations can be made without departing from the scope of the present invention.
