Description
【発明の詳細な説明】
信号の中でも音声電流は微弱で複雑なもので芯線自体に
発生ずる磁場による二次電流およびこれを保持４−る絶
縁物などの材質およびこれら相互間の物理的状態などに
より余計な電流が重畳されるのて忠実度の高い音響ケー
ブルを得ることは困難であるとされて居った。[Detailed Description of the Invention] Among the signals, the audio current is weak and complex, and includes secondary current due to the magnetic field generated in the core wire itself, the materials such as insulators that hold this current, and the physical conditions between them. It has been said that it is difficult to obtain an acoustic cable with high fidelity due to the superimposition of unnecessary current.
本発明はこれらの欠点を除去した新規な提案である。The present invention is a novel proposal that eliminates these drawbacks.
次に本発明の詳細な説明する。′
本発明は芯線を絶縁しこれに導電性外皮を被せ、これを
芯線の入力端末に接続するようにして芯線を保護するよ
うにした構造である。Next, the present invention will be explained in detail. ' The present invention has a structure in which the core wire is insulated and covered with a conductive outer sheath, and this is connected to the input terminal of the core wire to protect the core wire.
本発明に於ける導電性外皮とは銅テープ又シ銅細線を一
組したものでよく、又上述の説明では芯線に同電位外皮
を被せた基本を示したが、−酸ケーブルと同様にこれに
絶縁してアースシールドを施すことも出来る。The conductive sheath in the present invention may be a copper tape or a set of thin copper wires, and although the above explanation basically covers the core wire with the same potential sheath, this can be used in the same way as the -acid cable. It is also possible to insulate and provide an earth shield.
又これを二芯シールド形即ちバランス形ケーブルに実施
することも出来る。It is also possible to implement this in a two-conductor shielded or balanced cable.
Claims (1)
を芯線の入力端末に接続４−る用にし、外皮に電流が流
れないようにし、芯線と外皮を同極にし、反発作用によ
り芯線に二次電流の重畳を防ぐようにした同電位ケーブ
ル。The present invention insulates and covers the outside of the core wire with a conductive outer sheath, connects it to the input terminal of the core wire, prevents current from flowing through the outer sheath, makes the core wire and the outer sheath the same polarity, and uses repulsion to prevent current from flowing through the outer sheath. A cable with the same potential that prevents secondary current from being superimposed on the core wire.
