Description

【0001】
【発明の属する技術分野】
この発明は、電子機器の内部配線等に使用されるテープ電線及びテープ電線の製造方法に関するものである。
【0002】
【従来の技術】
電子複写機、ワードプロセッサー等の電子機器においては、特に可動部を配線する電線として、複数の導線をテープ状に形成した、いわゆるテープ電線が使用されている。このテープ電線は、薄いテープ状に形成されているために、小型化が要求される電子機器の内部配線に適しているとともに、ケーブルフォーミングが容易であること、コネクタ接続が容易であること等の利点を有している。
【0003】
図5を参照するに、従来、テープ電線装置101によりテープ電線を製造する場合、左右のフィルムロール103に巻かれた2枚の絶縁フィルムからなるシート状の絶縁体105は、一対のテープ繰出ロール107により引き出されて複数のダンサーロール109を介して各送込みローラ111により、側方から一対の仮付熱ロール113と同じ所定の速度の送り速度で仮付熱ロール113の外周部下側に沿って送り込まれると共に、平行に並んだ複数本の導体115は複数の案内ローラ117を経て下方から上方へ前記仮付熱ロール113へ送られる。
【0004】
前記絶縁体105は前記仮付熱ロール113の下方近傍に設けられた各静電気電極119より発生された静電気によって、前記各仮付熱ロール113の外周面の近傍に設けられた各カッタロール121より搬送手前側で前記各仮付熱ロール113に吸着される。
【0005】
そして、吸着状態を維持したまま絶縁体105は所定長さ送られた状態で、各カッタロール121が仮付熱ロール113と同期して回転し、各カッタロール121に備えられたカッタ123によって絶縁体105が同時に所定長さで切断される。
【0006】
切断された絶縁体105は、各カッタロール121の搬送方向後方側の位置に設けられた各静電気電極125により発生した静電気により各仮付熱ロール113への静電吸着力がさらに強められることになる。
【0007】
前記絶縁体105の切断完了とほぼ同時に、送込みロール111の回転を一時的に所定時間遅らせることで、すでに切断されている絶縁体105の後端部と次に切断される絶縁体105の先端部との間に所定の領域(間隔)が設けられることになる。そして、この領域が維持されたまま、すでに切断されている絶縁体105と次に切断される絶縁体105とが同速度で送られることになる。そして、上記領域が導体露出部となる。
【0008】
その後、切断された絶縁体105は吸着状態を維持したまま、同時に各熱付ロール113間に送り出された導体115と同期して送られ、導体115に熱により仮貼付される。この仮貼付された状態でさらに送り出されて一対の本付熱ロール127で完全に貼付されてテープ電線(フラットケーブル)129となり、複数の冷却ロール131で冷却される。その後、案内ローラ133を経た後、スリット装置135により必要な製品幅に応じて切断された後、引取装置137を介して巻取装置139に巻き取られることになる。

【発明が解決しようとする課題】
ところで、従来のテープ電線装置101においては、端子部の複数の導線115が露出されているために端子部の表面が汚れることがあるので、電子機器のコネクタとテープ電線129の端子部の導線115の接触不良が発生する恐れがある。また、近年の高密度化にともない、導体と導体の間隔が狭くなり、ゴミなどの付着などによりショートしてしまうことがある。
【0011】
この発明は上述の課題を解決するためになされたもので、その目的は、端子部の複数の導線を保護すると共にコネクタと接続する際には端子部の複数の導線を容易に露出し得るようにし、また、ゴミなどの付着をなくし、ショートを防ぐようにしたテープ電線及びテープ電線の製造方法を提供することにある。
【0012】
【課題を解決するための手段】
上記目的を達成するために請求項1によるこの発明のテープ電線は、並行する複数の導線をテープ状絶縁体で被覆して構成するテープ電線において、
前記複数の導線を上下から挟み込んで融着するテープ状絶縁体と、前記複数の導線を電子機器の端子に接続するためにテープ電線の端部に設けた端子部と、この端子部における上下のテープ状絶縁体のうちの少なくとも一方のテープ状絶縁体と前記複数の導線との間に介在した離型紙と、からなることを特徴とするものである。
【0013】
したがって、テープ電線の端子部の導線は離型紙の介在により容易に露出される。しかも、複数の導線が電子機器の端子に接続されるまでは端子部の導線がテープ状絶縁体により保護されているので、従来のようなテープ電線の端子部の導線の表面の汚れによる接触不良の可能性が低減される。また、ゴミなどの付着をなくし、ショートが防止される。
【0014】
請求項2によるこの発明のテープ電線の製造方法は、並行する複数の導線を上下からテープ状絶縁体で挟み込んで融着して製造するテープ電線の製造方法において、
前記複数の導線を電子機器の端子に接続するための端子部に該当する位置に、上下のテープ状絶縁体のうちの少なくとも一方のテープ状絶縁体と前記複数の導線との間に離型紙を介在せしめ、前記離型紙を介して前記複数の導線と上下のテープ状絶縁体で挟み込んで融着してテープ電線を製造し、このテープ電線の前記離型紙の位置で幅方向に切断することにより両端部に前記端子部を備えたテープ電線を製造することを特徴とするものである。
【0015】
したがって、複数の導線が離型紙を介在して上下のテープ状絶縁体間で挟み込んで加熱して融着されても離型紙と導線とは熱のために融着されることがないので、効率よくテープ電線が製造される。しかも、このテープ電線の離型紙の部分で切断分離されたテープ電線は、請求項1記載の作用と同様に、テープ電線の端子部の導線が離型紙の介在により容易に露出される。しかも、複数の導線が電子機器の端子に接続されるまでは端子部の導線がテープ状絶縁体により保護されているので、従来のようなテープ電線の端子部の導線の表面の汚れによる接触不良の可能性が低減される。また、ゴミなどの付着をなくし、ショートが防止される。
【0016】
請求項3によるこの発明のテープ電線の製造方法は、請求項2記載のテープ電線の製造方法において、前記離型紙を、接着剤を介して前記複数の導線又はテープ状絶縁体に仮付けしてから前記テープ電線を製造することを特徴とするものである。
【0017】
したがって、離型紙が導線又はテープ状絶縁体に容易に仮付けされるので、テープ電線が効率よく製造される。
【0018】
請求項4によるこの発明のテープ電線の製造方法は、請求項2又は3記載のテープ電線の製造方法において、前記離型紙を、テープ電線の長さ方向に一定間隔で介在せしめることを特徴とするものである。
【0019】
したがって、離型紙がテープ電線の長さ方向に一定間隔で導線又はテープ状絶縁体に介在されるので、テープ電線が効率よく製造される。
【0020】
請求項5によるこの発明のテープ電線の製造方法は、請求項2又は4記載のテープ電線の製造方法において、前記離型紙が、前記端子部に該当する位置を櫛歯部とした櫛歯形状のテープであることを特徴とするものである。
【0021】
したがって、離型紙が端子部に該当する位置を櫛歯部とした櫛歯形状のテープであるので、離型紙が接着剤を介して複数の導線又はテープ状絶縁体に仮付けする必要がなく、複数の導線と少なくとも一方のテープ状絶縁体との間に容易に介在されるため、テープ電線が効率よく製造される。また、櫛歯形状の離型紙はテープ状の離型紙から櫛歯形状に成形する際に、櫛歯部を前後に位置せしめた状態で左右にほぼ対称的な2つの櫛歯形状の離型紙が型取られるので、梯子状の離型紙よりも効率的である。
【0022】
【発明の実施の形態】
以下、この発明の実施の形態について図面を参照して説明する。
【0023】
図1を参照するに、この実施の形態に係わるテープ電線1は、並行する複数の導線3が2枚のテープ状絶縁体5、7で上下から挟み込んで融着され、被覆されている。また、テープ電線1の一端もしくは両端部には上記の複数の導線3を電子機器の端子に接続するための端子部9が設けられており、この端子部9における図1において上側のテープ状絶縁体5と前記複数の導線3との間には離型紙11が介在されている。
【0024】
なお、離型紙11は下側のテープ状絶縁体7と前記複数の導線3との間に設けられても、あるいは上下両方のテープ状絶縁体5、7と前記複数の導線3との間にそれぞれ設けられても構わない。いずれにしても上下のテープ状絶縁体5、7のうちの少なくとも一方のテープ状絶縁体と前記複数の導線3との間に介在されていれば構わない。
【0025】
上記構成により、テープ電線1は、端子部9が電子機器のコネクタの端子に接続されるまでの間は、端子部9の複数の導線3がテープ状絶縁体5、7により保護されているので複数の導線3は汚れない。しかも、実際にコネクタの端子に接続されるときは、離型紙11を介在している上側のテープ状絶縁体5が容易に剥がされ、図1の矢印で示されているように反対側へ折り返されるので複数の導線3が簡単に露出される。また、複数の各導線3が下側のテープ状絶縁体7から簡単に剥がすことができ、この下側のテープ状絶縁体7も反対側へ折り返され、上記の複数の各導線3がコネクタの端子へ接続される。
【0026】
したがって、テープ電線1の端子部9の複数の導線3は容易に露出でき、且つ従来のようなテープ電線1の端子部9の導線3の表面の汚れによる接触不良の可能性が低減される。また、ゴミなどの付着をなくし、ショートするのを防止することができる。
【0027】
次に、この発明の第1の実施の形態のテープ電線の製造方法について図面を参照して説明する。
【0028】
図2を参照するに、テープ電線1の製造方法としては、並列された複数の導線3が一対の加熱ローラ13の間に送り出されると共に、テープ状の絶縁樹脂からなる2枚のテープ状絶縁体5、7が上記の複数の導線3を上下から挟み込むように上記の一対の加熱ローラ13の間に送り出される。また、この実施の形態では上記の複数の導線3の図2において上面側にはほぼ長方形状をなす離型紙11が長さ方向に一定の間隔で接着剤(図示省略)を介して貼着されており、この状態で上記の一対の加熱ローラ13の間に送り出される。なお、上記の接着剤は離型紙11の裏の一部に付けられており、その部分の導線3はダミー線とされる。
【0029】
したがって、上記の複数の導線3は加熱ローラ13にて2枚のテープ状絶縁体5、7に挟み込まれると共に加熱ローラ13で例えば100〜150°Cで加熱されて2枚のテープ状絶縁体5、7で融着され被覆される。また、上側のテープ状絶縁体5と複数の導線3との間に離型紙11を介在した部分では離型紙11と複数の導線3、並びにテープ状絶縁体5が熱のために融着することはないので容易に剥がれる。以上のようにして、テープ電線15が製造され、ロール状に巻き取られる。
【0030】
なお、この実施の形態では離型紙11は上側のテープ状絶縁体5と複数の導線3との間に設けられているが、下側のテープ状絶縁体7と複数の導線3との間に設けられても、あるいは上下両方のテープ状絶縁体5、7と前記複数の導線3との間に設けられても構わない。いずれにしても上下のテープ状絶縁体5、7のうちの少なくとも一方のテープ状絶縁体と前記複数の導線3との間に介在されていれば構わない。
【0031】
さらに、この第1の実施の形態では離型紙11は複数の導線3の図2において上面側に接着剤を介して仮付けされているが、テープ状絶縁体5又は7の裏面に仮付けされるようにしても構わない。また、離型紙11は複数の導線3を電子機器の端子に接続するための端子部9に該当する位置に設けられており、この実施の形態ではテープ電線15の長さ方向に一定の間隔で設けられているが、離型紙11の配置状態は上記の端子部9に該当する位置に合わせて不定間隔で設けられても構わない。
【0032】
また、上記のロール状に巻き取られたテープ電線15は、離型紙11を介在した部分の長手方向のほぼ中央で幅方向に切断分離されることにより、図1に示されるような一端部又は両端部に端子部9を備えたテープ電線1が製造される。なお、テープ状絶縁体5、7の幅方向の側縁からはみ出した離型紙11は前記側縁に沿って切断される。
【0033】
図3を参照するに、この発明の第2の実施の形態のテープ電線の製造方法としては、図1に示されている第1の実施の形態のテープ電線の製造方法とほぼ同様であるので、同一部材は同符号にて説明する。
【0034】
離型紙17としては、テープ状の長手方向に一定間隔で櫛歯部19が設けられている、所謂櫛歯形状に形成された離型紙17が用いられる。この櫛歯形状の離型紙17は、この実施の形態では上側のテープ状絶縁体と複数の導線3との間に離型紙17の櫛歯部19を介在するようにして一対の加熱ローラ13の間に送り出され、前述した第1の実施の形態と同様に一対の加熱ローラ13の間で複数の導線3が上下のテープ状絶縁体5、7で挟み込まれて融着され、且つ離型紙17の櫛歯部19が一定間隔に介在されたテープ電線21が製造され、ロール状に巻き取られる。
【0035】
このテープ電線21は、剥離紙の櫛歯形状の櫛歯部19がテープ電線1の幅方向の両側縁に沿って切断されることにより縦辺部23も分離され、且つ離型紙17の櫛歯部19を介在した部分の長手方向のほぼ中央で幅方向に切断分離されることにより、図1に示されるような一端部又は両端部に端子部9を備えたテープ電線1が製造される。
【0036】
図4に示されているように、櫛歯形状の離型紙17の場合は櫛歯部19が前後に位置される状態で左右にほぼ対称的な2つの櫛歯形状に形成されるようにして型抜きされる。つまり、櫛歯形状の離型紙17の場合は、梯子状の横辺部に相当する部分が左右の2つの櫛歯形状の櫛歯部19を前後するようにしてレイアウトされることにより、同じ面積のテープ状の離型紙に対して梯子状の離型紙の場合より2倍の離型紙を効率よく得ることができるという点で、櫛歯形状の離型紙17の方が望ましい。
【0037】
なお、図3における第2の実施の形態のテープ電線の製造方法では、離型紙17の配置状態などの他の事項が、前述した第1の実施の形態とほぼ同様である。但し、この場合は離型紙17を仮付けする必要がないので接着剤は使用されず、ダミー線も必要ないというメリットがある。
【0038】
なお、この発明は前述した実施の形態に限定されることなく、適宜な変更を行うことによりその他の態様で実施し得るものである。
【0039】
【発明の効果】
以上のごとき発明の実施の形態の説明から理解されるように、請求項1の発明によれば、離型紙の介在によりテープ電線の端子部の導線を容易に露出できる。しかも、複数の導線が電子機器の端子に接続されるまではテープ状絶縁体により端子部の導線を保護できるので、従来のようなテープ電線の端子部の導線の表面の汚れによる接触不良の可能性を低減できる。また、ゴミなどの付着をなくし、ショートするのを防止することができる。
【0040】
請求項2の発明によれば、複数の導線を離型紙を介在して上下のテープ状絶縁体間で挟み込んで加熱して融着しても離型紙と導線は熱のために融着されないので、テープ電線を効率よく製造できる。しかも、このテープ電線の離型紙の部分で切断分離することにより容易にテープ電線を製造でき、このテープ電線は、請求項1記載の効果と同様に、離型紙の介在によりテープ電線の端子部の導線を容易に露出できる。しかも、複数の導線が電子機器の端子に接続されるまではテープ状絶縁体により端子部の導線を保護できるので、従来のようなテープ電線の端子部の導線の表面の汚れによる接触不良の可能性を低減できる。また、ゴミなどの付着をなくし、ショートするのを防止することができる。
【0041】
請求項3の発明によれば、離型紙を導線又はテープ状絶縁体に容易に仮付けできるので、テープ電線を効率よく製造できる。
【0042】
請求項4の発明によれば、離型紙をテープ電線の長さ方向に一定間隔で導線又はテープ状絶縁体に介在できるので、テープ電線を効率よく製造できる。
【0043】
請求項5の発明によれば、離型紙が端子部に該当する位置を櫛歯部とした櫛歯形状のテープであるので、離型紙は接着剤を介して複数の導線又はテープ状絶縁体に仮付けする必要がなく、複数の導線と少なくとも一方のテープ状絶縁体との間に容易に介在できるため、プリテープ電線を効率よく製造できる。また、櫛歯形状の離型紙の場合、テープ状の離型紙から櫛歯形状に成形する際に、櫛歯部を前後に位置せしめた状態で左右にほぼ対称的な2つの櫛歯形状の離型紙を型取られるので、梯子状の離型紙よりも効率的に型取ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tape electric wire used for internal wiring and the like of an electronic device, and a method of manufacturing the tape electric wire.
[0002]
[Prior art]
In an electronic device such as an electronic copying machine or a word processor, a so-called tape wire, in which a plurality of conductive wires are formed in a tape shape, is used as a wire for wiring a movable portion. Since this tape wire is formed in a thin tape shape, it is suitable for the internal wiring of electronic devices that require miniaturization, and it is easy to form cables and easy to connect connectors. Has advantages.
[0003]
Referring to FIG. 5, conventionally, when a tape electric wire is manufactured by a tape electric wire device 101, a sheet-like insulator 105 made of two insulating films wound on left and right film rolls 103 is formed by a pair of tape feeding rolls. Each of the feed rollers 111 is pulled out by a plurality of dancer rolls 109, and is fed from the side along the lower side of the outer peripheral portion of the temporarily attached heat roll 113 at a feed speed of the same predetermined speed as the pair of temporarily attached heat rolls 113. The plurality of conductors 115 arranged in parallel are sent from the lower side to the upper side through the plurality of guide rollers 117 to the temporary attaching heat roll 113.
[0004]
The insulator 105 is separated from the cutter rolls 121 provided in the vicinity of the outer peripheral surface of each of the temporarily attached heat rolls 113 by static electricity generated by each of the electrostatic electrodes 119 provided below and below the temporary attached heat rolls 113. At the front side of the conveyance, the heat is absorbed by each of the temporary-attached heat rolls 113.
[0005]
Then, in a state where the insulator 105 is fed for a predetermined length while maintaining the suction state, each cutter roll 121 rotates in synchronization with the temporary-attached heat roll 113, and is insulated by the cutter 123 provided on each cutter roll 121. The body 105 is simultaneously cut to a predetermined length.
[0006]
The cut insulator 105 further enhances the electrostatic attraction force to each of the temporarily attached heat rolls 113 due to static electricity generated by each of the electrostatic electrodes 125 provided on the rear side in the transport direction of each of the cutter rolls 121. Become.
[0007]
Almost simultaneously with the completion of the cutting of the insulator 105, by temporarily delaying the rotation of the feeding roll 111 for a predetermined time, the rear end of the already cut insulator 105 and the front end of the next cut insulator 105 A predetermined area (interval) is provided between the first and second sections. Then, while this area is maintained, the insulator 105 already cut and the insulator 105 to be cut next are sent at the same speed. And the above-mentioned area becomes a conductor exposure part.
[0008]
Thereafter, the cut insulator 105 is simultaneously sent while being kept in the suction state and synchronized with the conductor 115 sent out between the heating rolls 113, and is temporarily attached to the conductor 115 by heat. In this state of temporary attachment, the tape is further fed out and completely attached by a pair of permanent heating rolls 127 to form a tape electric wire (flat cable) 129, which is cooled by a plurality of cooling rolls 131. Then, after passing through the guide roller 133, it is cut by the slit device 135 according to the required product width, and then wound up by the winding device 139 via the pulling device 137.

[Problems to be solved by the invention]
By the way, in the conventional tape electric wire device 101, since the surface of the terminal portion may be dirty because the plurality of conductors 115 of the terminal portion are exposed, the connector of the electronic device and the conductor 115 of the terminal portion of the tape electric wire 129 may be dirty. Contact failure may occur. Further, with the recent increase in density, the distance between conductors has become narrower, and short-circuiting may occur due to adhesion of dust or the like.
[0011]
The present invention has been made to solve the above-described problem, and an object of the present invention is to protect a plurality of conductors of a terminal and to easily expose a plurality of conductors of a terminal when connecting to a connector. Another object of the present invention is to provide a tape electric wire and a method for manufacturing the tape electric wire, in which adhesion of dust and the like is eliminated and a short circuit is prevented.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, a tape electric wire according to the present invention according to claim 1 is a tape electric wire configured by covering a plurality of parallel conductive wires with a tape-shaped insulator.
A tape-shaped insulator that sandwiches and fuses the plurality of conductive wires from above and below, a terminal portion provided at an end of a tape wire for connecting the plurality of conductive wires to terminals of an electronic device, and a vertical portion of the terminal portion. It is characterized by comprising at least one of the tape-shaped insulators and a release paper interposed between the plurality of conductive wires.
[0013]
Therefore, the conducting wire of the terminal portion of the tape electric wire is easily exposed by the interposition of the release paper. In addition, since the conductors of the terminal portion are protected by the tape-shaped insulator until a plurality of conductors are connected to the terminals of the electronic device, poor contact due to contamination of the surface of the conductor of the terminal portion of the conventional tape wire is caused. Is reduced. In addition, adhesion of dust and the like is eliminated, and short circuit is prevented.
[0014]
The method for manufacturing a tape electric wire according to the present invention according to claim 2 is a method for manufacturing a tape electric wire in which a plurality of parallel conductive wires are sandwiched and fused by a tape-shaped insulator from above and below, and
At a position corresponding to a terminal portion for connecting the plurality of conductors to a terminal of an electronic device, release paper is provided between at least one of the upper and lower tape-like insulators and the plurality of conductors. Interposed, sandwiched between the plurality of conductors and the upper and lower tape-shaped insulators via the release paper and fused to produce a tape wire, and cut in the width direction at the position of the release paper of the tape wire. A tape electric wire having the terminal portions at both ends is manufactured.
[0015]
Therefore, even if a plurality of conductors are sandwiched between the upper and lower tape-shaped insulators with the release paper interposed therebetween and heated and fused, the release paper and the conductors are not fused due to heat, so the efficiency is improved. Tape wires are often manufactured. Moreover, in the tape electric wire cut and separated at the release paper portion of the tape electric wire, the conductive wire of the terminal portion of the tape electric wire is easily exposed by the interposition of the release paper, as in the operation of the first aspect. In addition, since the conductors of the terminal portion are protected by the tape-shaped insulator until a plurality of conductors are connected to the terminals of the electronic device, poor contact due to contamination of the surface of the conductor of the terminal portion of the conventional tape wire is caused. Is reduced. In addition, adhesion of dust and the like is eliminated, and short circuit is prevented.
[0016]
According to a third aspect of the present invention, in the method for manufacturing a tape electric wire according to the second aspect, the release paper is temporarily attached to the plurality of conductive wires or the tape-like insulator via an adhesive. From which the tape wire is manufactured.
[0017]
Therefore, since the release paper is easily temporarily attached to the conductor or the tape-shaped insulator, the tape electric wire is efficiently manufactured.
[0018]
According to a fourth aspect of the present invention, there is provided a method of manufacturing a tape electric wire according to the second or third aspect, wherein the release paper is interposed at regular intervals in a length direction of the tape electric wire. Things.
[0019]
Accordingly, since the release paper is interposed between the conductor or the tape-shaped insulator at regular intervals in the length direction of the tape electric wire, the tape electric wire is manufactured efficiently.
[0020]
According to a fifth aspect of the present invention, there is provided a tape electric wire manufacturing method according to the second or fourth aspect, wherein the release paper has a comb-teeth shape in which a position corresponding to the terminal portion is a comb-teeth portion. It is characterized by being a tape.

The tape electric wire 1 having the terminal portions 9 at both ends is manufactured. Note that the release paper 11 protruding from the side edges of the tape-shaped insulators 5 and 7 in the width direction is cut along the side edges.
[0033]
Referring to FIG. 3, the method for manufacturing the tape electric wire according to the second embodiment of the present invention is substantially the same as the method for manufacturing the tape electric wire according to the first embodiment shown in FIG. , The same members will be described with the same reference numerals.
[0034]
As the release paper 17, a release paper 17 formed in a so-called comb-teeth shape in which comb-shaped portions 19 are provided at regular intervals in a tape-like longitudinal direction is used. In this embodiment, the comb-shaped release paper 17 is formed of a pair of heating rollers 13 such that the comb teeth 19 of the release paper 17 are interposed between the upper tape-shaped insulator and the plurality of conductive wires 3.
