Description
【考案の詳細な説明】
本考案は、コンピュータ内の配線等に用いられる信号伝
送用遮蔽ケーブルの改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement in a shielded signal transmission cable used for wiring inside a computer.
コンピュータの配線に用いられる信号伝送用遮蔽ケーブ
ルは高周波誘導の外に400Hz程度の低周波のコンピ
ュータ電源から低周波誘導を受ける。Shielded signal transmission cables used for computer wiring receive not only high frequency induction but also low frequency induction from a computer power supply with a low frequency of about 400 Hz.
高周波誘導に対しては静電遮蔽が有効であるが、低周波
誘導は電磁誘導であるので電磁遮蔽でなければならない
ため上記の信号伝送用遮蔽ケーブルには両方の遮蔽手段
を必要とする。Electrostatic shielding is effective for high-frequency induction, but since low-frequency induction is electromagnetic induction, it must be electromagnetic shielded, so the above-mentioned signal transmission shielded cable requires both types of shielding means.
従来の信号伝送用遮蔽ケーブルの遮蔽手段は各対の上に
巻かれた導電性テープとこの上に巻かれた磁性テープと
から戒っていたので外径が大きくなる上に可撓性が小さ
く、また導電性テープは接地線に接続する必要があり、
このため配線時の作業性が低い欠点があった。Conventional shielding means for shielded signal transmission cables consisted of a conductive tape wrapped over each pair and a magnetic tape wrapped on top of the conductive tape, which resulted in a larger outer diameter and less flexibility. , and the conductive tape must be connected to the ground wire,
For this reason, there was a drawback that workability during wiring was low.
本考案の目的は、外径が小さく可撓性が大きく、また接
地を容易に行うことができる信号伝送用遮蔽ケーブルを
提供することにある。An object of the present invention is to provide a shielded cable for signal transmission that has a small outer diameter, is highly flexible, and can be easily grounded.

FIG. 1 shows a shielded cable 10 for signal transmission according to the present invention, and this shielded cable is separated from an aggregate of a plurality of pairs 12.
各対12は、2本の絶縁導線14.14’を撚合せて形
成されている。Each pair 12 is formed by twisting together two insulated conductive wires 14,14'.
各対12は遮蔽手段16を有するが、この遮蔽手段は、

性テープ20とから戒っている。Each pair 12 has shielding means 16, which shielding means:
As shown in FIG. 2, two insulated conductive wires 14 forming a pair
.. 14' and a bare conductor 18, such as an uninsulated copper wire, twisted together with the insulated conductor 14; 14' and the bare conductor 1;
The magnetic tape 20, such as iron tape, is wrapped over the twisted body of the magnetic tape 8 and the magnetic tape 20.
静電遮蔽は良導体である導線18の導電性とこれに接触
して絶縁導線14,14′を包囲する磁性テープ20の
若干の導電性で行い、電磁誘導は前記導線18の導電性
と磁性テープ20の透磁性により行う。Electrostatic shielding is achieved by the conductivity of the conductive wire 18, which is a good conductor, and the slight conductivity of the magnetic tape 20 that comes into contact with it and surrounds the insulated conductive wires 14, 14'. This is done with a magnetic permeability of 20.
導線18は対12を形成する際に対を構成する絶縁導線
14,14′の撚合せ時に一緒に撚合せるが、第2図か

外径が大きくなることがなく、またこの導線18はその
まま接地線として用いることができる。The conductor wire 18 is twisted together when the insulated conductor wires 14 and 14' constituting the pair are twisted together to form the pair 12, but as can be seen from FIG. The diameter does not increase, and the conducting wire 18 can be used as it is as a grounding wire.
本考案によれば、上記のように、電磁遮蔽手段は対を構

ことができる実益がある。According to the present invention, as described above, the electromagnetic shielding means is shielded from uninsulated conductors twisted together with the two insulated conductors constituting the pair, so compared to the conventional wrapping of conductive tape. This allows the outer diameter of the cable to be small, does not impair the flexibility of the cable, and allows the uninsulated conductor to be used as a grounding wire, making wiring work more efficient. Furthermore, since there is no need for the process of winding the conductive tape, there is the practical benefit of good workability and low cost manufacturing.
