従来、高真空環境下で複数の回路配線を必要とする場合、例えばカブトンチューブ（カブトンは登録商標）に銀メッキ銅線を通した構造のケーブルを各配線毎に個別に用意して用いていた。しかしながら、この種、耐真空用ケーブルは、経済性の面で問題があるとともに、ケーブルの長さが規定され、可撓性に難があることから汎用性に乏しいという問題があった。   Conventionally, when a plurality of circuit wirings are required in a high vacuum environment, for example, a cable having a structure in which a silver plated copper wire is passed through a kabuton tube (kabuton is a registered trademark) has been separately prepared for each wiring. . However, this type of vacuum-resistant cable has a problem in terms of economy, and has a problem that the length of the cable is prescribed and flexibility is difficult, so that the versatility is poor.

本発明は上記実情に鑑みなされたもので、高真空環境下での使用を容易に可能にした、経済的に有利で、かつ任意長に加工できる汎用性に富む耐真空複合ケーブルの製造方法および耐真空複合ケーブルを提供することを目的とする。   The present invention has been made in view of the above circumstances, and can be easily used in a high vacuum environment, is economically advantageous, and has a versatile vacuum-resistant composite cable that can be processed to an arbitrary length. An object is to provide a vacuum-resistant composite cable.

本発明は、耐真空複合ケーブルの製造方法の製造方法であって、フッ素系樹脂により銀メッキ銅線の導体に被膜を施した複数本のケーブルをフッ素系樹脂のマンドレルの周囲に巻き付け、前記マンドレルの周囲に巻き付けた前記複数本のケーブルを編組シールドの外皮で覆って製造した複合ケーブルを任意の布線長に切断加工した後、前記マンドレルを前記複合ケーブルから引き抜き、前記複数本のケーブルの前記巻き付けに伴う撚りを戻して伸張した状態でベーキングすることを特徴とする。 The present invention is a method for producing a method for producing a vacuum-proof composite cable, wound a plurality of cables subjected to coating the conductor of the silver-plated copper wire with a fluorine-based resin around a mandrel of a fluorine-based resin, the mandrel After cutting the composite cable manufactured by covering the plurality of cables wound around the periphery with a sheath of a braided shield into an arbitrary wiring length, the mandrel is pulled out from the composite cable , and the plurality of cables are Baking is performed in a stretched state by unwinding the twist associated with winding.

また。本発明は、耐真空複合ケーブルであって、耐真空複合ケーブルの製造方法によって製造されたケーブルを高真空環境の回路配線に使用することを特徴とする。
Also. The present invention is a vacuum resistant composite cable, wherein the cable manufactured by the method of manufacturing a vacuum resistant composite cable is used for circuit wiring in a high vacuum environment .

高真空環境下での使用を可能にした、経済的に有利で、かつ任意長に加工できる汎用性に富んだ耐真空複合ケーブルが提供できる。   A versatile vacuum resistant composite cable that can be used in a high vacuum environment, is economically advantageous, and can be processed to an arbitrary length can be provided.

以下図面を参照して本発明の実施形態を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

本発明の実施形態に於ける耐真空複合ケーブルの構造例を図１に示す。本発明の実施形態に係る耐真空複合ケーブル１０は、フッ素系樹脂により導体被膜を施した複数本のケーブル１２，１２，…をマンドレル１１の周囲に巻き付けて外皮（シース）１３で覆った構造としている。   An example of the structure of the vacuum-resistant composite cable in the embodiment of the present invention is shown in FIG. The vacuum-resistant composite cable 10 according to the embodiment of the present invention has a structure in which a plurality of cables 12, 12,... Coated with a conductor coating with a fluorine-based resin are wound around a mandrel 11 and covered with an outer sheath (sheath) 13. Yes.

マンドレル１１は、例えばＰＴＦＥ若しくはＰＦＡ等のフッ素系樹脂により構成され、外皮１３の略中心に位置する。このマンドレル１１の周囲に複数本のケーブル１２，１２，…が巻き付けられる。   The mandrel 11 is made of, for example, a fluororesin such as PTFE or PFA, and is positioned substantially at the center of the outer skin 13. A plurality of cables 12, 12,... Are wound around the mandrel 11.

マンドレル１１を中心に、その周囲に設けられる複数本のケーブル１２，１２，…は、それぞれ、導体（芯線）に銀メッキ銅線を用い、この導体（芯線）を、ＰＴＦＥ若しくはＰＦＡ等のフッ素系樹脂で被覆している。ここでは、フッ素系樹脂の中でも不純物の少ないＰＴＦＥを選定して、このＰＴＦＥにより銀メッキ銅線を電気的に絶縁被覆している。また、ここでは複数本のケーブル１２，１２，…のうち、ケーブル内に示す符号１〜６はそれぞれシングル線、７〜１５はそれぞれ同軸線である。   The plurality of cables 12, 12,... Provided around the mandrel 11 use a silver plated copper wire as a conductor (core wire), and the conductor (core wire) is made of a fluorine-based material such as PTFE or PFA. Covered with resin. Here, PTFE with few impurities is selected from among the fluorine-based resins, and the silver-plated copper wire is electrically insulated and coated with this PTFE. Moreover, here, among the plurality of cables 12, 12,..., Reference numerals 1 to 6 shown in the cables are single lines, and 7 to 15 are coaxial lines.

これら複数本のケーブル１２，１２，…を被覆する外皮１３は、網組シールドにより構成される。以降、この外皮を網組シールドと呼ぶ。   The outer cover 13 that covers the plurality of cables 12, 12,... Is constituted by a netting shield. Hereinafter, this outer skin is called a netting shield.

図２は上記した本発明の実施形態に係る耐真空複合ケーブルを耐真空用に加工する際のベーキングに至るまでの工程を説明するためのもので、ここでは、マンドレル１１を中心に、その周囲に設けられる複数本のケーブル１２，１２，…を簡略化して示している。   FIG. 2 is a view for explaining the process up to baking when the vacuum-resistant composite cable according to the embodiment of the present invention is processed for vacuum resistance. Here, the mandrel 11 is the center and the surrounding area is shown. A plurality of cables 12, 12,...

この図２に示す工程では、先ず、同図（ａ）に示すように、長尺の複合ケーブル１０を任意の布線長に加工（切断）する。   In the process shown in FIG. 2, first, as shown in FIG. 2A, the long composite cable 10 is processed (cut) into an arbitrary wiring length.

つぎに、任意の布線長に加工（切断）した複合ケーブル１０から、図２（ｂ）に示すように、マンドレル１１を引き抜く。この際、マンドレル１１の周囲に設けられる複数本のケーブル１２，１２，…は、それぞれＰＴＦＥを被覆材としており、ＰＴＦＥは、周知の通り、滑沢性を有し、極めて低い摩擦係数を示す樹脂であることから、また、マンドレル１１も同様の樹脂であることから、マンドレル１１の引き抜き作業を抵抗なく極めて簡単に行うことができる。   Next, as shown in FIG. 2 (b), the mandrel 11 is pulled out from the composite cable 10 processed (cut) into an arbitrary wiring length. At this time, the plurality of cables 12, 12,... Provided around the mandrel 11 each have PTFE as a covering material. As is well known, PTFE is a resin that has a lubricity and exhibits a very low coefficient of friction. Therefore, since the mandrel 11 is also a similar resin, the mandrel 11 can be pulled out very easily without resistance.

複合ケーブル１０からマンドレル１１を引き抜くことによって、網組シールド１３内に於いてケーブル１２，１２，…間隙が生じる。   By pulling out the mandrel 11 from the composite cable 10, the cables 12, 12,...

この状態で、図２（ｃ）に示すように、網組シールド１３内の各ケーブル１２，１２，…に於ける、巻き付けに伴う撚りを戻し、各ケーブル１２，１２，…をそれぞれ引き伸ばして伸張状態にする。   In this state, as shown in FIG. 2 (c), each cable 12, 12,... In the net assembly shield 13 is unwound by winding, and each cable 12, 12,. Put it in a state.

このような加工を施した後、ベーキング工程に入り、複合ケーブル１０を加熱処理して、複合ケーブル１０の各要素から吸着ガスを脱離させる。この際、各ケーブル１２，１２，…は、網組シールド１３内で、かつ互いに間隙を有した状態にあることから、網組シールド１３内にはケーブル相互の間を含んで空気溜まりは発生せず、従ってガス抜き効果の高いベーキングが行える。また、上記各ケーブル１２，１２，…の導体に、銀メッキ銅線を用いていることから、ケーブルからのガス放出を抑制できる。   After performing such processing, a baking process is started, and the composite cable 10 is heat-treated to desorb the adsorbed gas from each element of the composite cable 10. At this time, the cables 12, 12,... Are in the net assembly shield 13 and are in a state of having a gap therebetween, so that an air pocket is generated in the net assembly shield 13 including between the cables. Therefore, baking with high degassing effect can be performed. Moreover, since the silver plating copper wire is used for the conductor of each said cable 12, 12, ..., the gas emission from a cable can be suppressed.
