Description
【0001】[0001]
本考案は電磁波を遮蔽するための遮蔽付フラットケーブルの改良に関するもの である。 The present invention relates to an improvement of a shielded flat cable for shielding electromagnetic waves.
【0002】[0002]
一般に電子、電気機器の内部配線に使用されるフラットケーブルは図1に示す 如く同一平面上に複数本の導体2,2´,2´´を所望間隔毎に並設しその上下 から接着層付絶縁性フィルムにて挟持して絶縁層3を設けて一体化したものであ る。 Generally, a flat cable used for internal wiring of electronic and electric equipment has a plurality of conductors 2, 2 ', 2 "arranged in parallel on the same plane at desired intervals as shown in FIG. The insulating layer 3 is sandwiched between insulating films to provide an insulating layer 3 and integrated.
【0003】 而して上記の如き配線において、フラットケーブルが電磁波の影響をうけ易い 場合又は電磁波を放射し易いものである場合これを防御するために図2及び図3 に示す如く、当該フラットケーブル1の上面に、電磁遮蔽用金属層例えば銅、ア ルミ、鉄等の箔5を絶縁性接着層6及び遮蔽絶縁層7にて挟持した構造の遮蔽複 合テープ4を配置密着せしめて遮蔽付フラットケーブル8となしているものであ る。Therefore, in the above wiring, when the flat cable is easily affected by electromagnetic waves or easily radiated electromagnetic waves, in order to prevent this, as shown in FIG. 2 and FIG. 1. A shielding composite tape 4 having a structure in which an electromagnetic shielding metal layer, for example, a foil 5 of copper, aluminum, iron or the like is sandwiched between an insulating adhesive layer 6 and a shielding insulating layer 7 is arranged on the upper surface of 1 and is shielded by being adhered thereto. This is the flat cable 8.
【0004】 しかしこのように構成した遮蔽付フラットケーブル8ではフラットケーブル1 の上面を遮蔽複合テープ4にて覆っているものであるが、この遮蔽複合テープに おいて絶縁接着層を設ける理由はフラットケーブルに対し、その取付作業性を容 易になしうると共に電気絶縁性にすることによりフラットケーブルの導体に接触 するも地絡をおこさないためである。又遮蔽複合テープの表面に絶縁性フィルム による遮蔽絶縁層を設ける理由は遮蔽金属層が他の機器の足に触れて地絡を生じ ないためである。However, in the thus-configured shielded flat cable 8, the upper surface of the flat cable 1 is covered with the shielding composite tape 4, but the reason why the insulating adhesive layer is provided in this shielding composite tape is flat. This is because the workability of mounting the cable can be easily achieved, and by making the cable electrically insulative, it does not cause a ground fault even if it comes into contact with the conductor of the flat cable. In addition, the reason why the shielding insulating layer made of an insulating film is provided on the surface of the shielding composite tape is that the shielding metal layer does not come into contact with the foot of another device and cause a ground fault.
【0005】 然しながらこのように遮蔽付フラットケーブル8を形成したとしても、前記の 如くフラットケーブルを内部配線するに際し、図4に示す如くフラットケーブル 8の端部にコネクタ9を取付けんとする場合、電磁波にて防御される部分はフラ ットケーブル8のみであり、コネクタ9は露出状態になっているため該コネクタ 9は容易に電磁波の影響をうけるか或は該コネクタから電磁波を放射するという 問題があった。However, even if the shielded flat cable 8 is formed in this way, when the flat cable 8 is internally wired as described above, when the connector 9 is attached to the end of the flat cable 8 as shown in FIG. Since only the flat cable 8 is protected by electromagnetic waves and the connector 9 is exposed, there is a problem that the connector 9 is easily affected by the electromagnetic wave or emits the electromagnetic wave from the connector. It was
【0006】 なお図において10はプリント基盤である。In the figure, 10 is a print substrate.
【0007】 この問題を解決するためには、上記コネクタ9の部分にも電磁波を防御するた めにフラットケーブルの上面に設けた遮蔽複合テープと同様のテープを設けたコ ネクタを使用すればよいが、新規に遮蔽複合テープを取付けるためには著しくコ スト高になると共に作業が煩雑となり、作業性を阻害するものであった。In order to solve this problem, a connector provided with a tape similar to the shielding composite tape provided on the upper surface of the flat cable in order to protect the electromagnetic wave from the connector 9 may be used. However, in order to newly install the shielding composite tape, the cost becomes remarkably high and the work becomes complicated, which hinders the workability.

本考案はかかる現状に鑑み鋭意研究を行った結果、フラットケーブルの上面に 設けた遮蔽複合テープを有効に利用し、該遮蔽複合テープのみにてフラットケー ブルの部分と同時にコネクタの部分をも電磁波による被害を遮蔽するようにした 遮蔽付フラットケーブルを開発したものである。 As a result of earnest research in view of the present situation, the present invention effectively uses the shield composite tape provided on the upper surface of the flat cable, and the shield composite tape alone is used to electromagnetically affect the flat cable portion as well as the connector portion. This is the development of a shielded flat cable designed to shield the damage caused by

本考案は同一平面上に複数本の導体を長手方向に沿って所望間隔毎に並設し、 その両側に前記導体の端部を所望長露出させた状態に絶縁層を設けたフラットケ ーブルの片面絶縁層上に電磁波遮蔽用金属層を中層とした遮蔽複合テープを、前 記フラットケーブルの両端より所望の長さだけ突出し、かつ剥離させた状態にな るように配置密着せしめたことを特徴とするものである。 The present invention is a single-sided flat cable in which a plurality of conductors are arranged in parallel on the same plane along the longitudinal direction at desired intervals, and an insulating layer is provided on both sides of the conductor with the end portions of the conductors exposed to the desired length. A shielding composite tape having an electromagnetic wave shielding metal layer as an intermediate layer on the insulating layer is arranged and adhered so as to protrude from both ends of the flat cable by a desired length and to be peeled off. To do.
【0010】[0010]
本考案の遮蔽付フラットケーブルは図5および図6に示す如くフラットケーブ ル1の片面に配置密着される遮蔽複合テープ11は、その端部が所定長前記フラ ットケーブルが突出し、かつ剥離させた状態に形成されているため、該フラット ケーブル1の使用に際し、図7に示す如く該フラットケーブル1の端部導体にコ ネクタ9を接続する場合、突出し剥離されている部分の遮蔽複合テープ11にて コネクタ9の上面をも容易に覆うことが出来るため、該コネクタを電磁波からの 影響を十分に防御しうる遮蔽付フラットケーブル12をうることが出来るのであ る。 The shielded flat cable of the present invention is placed on one side of the flat cable 1 as shown in FIGS. 5 and 6, and the shielded composite tape 11 is in close contact with the flat cable for a predetermined length, and the flat cable is projected and peeled off. Therefore, when the flat cable 1 is used, when the connector 9 is connected to the end conductor of the flat cable 1 as shown in FIG. Since the upper surface of the connector 9 can be easily covered, it is possible to obtain the shielded flat cable 12 capable of sufficiently protecting the connector from the influence of electromagnetic waves.
【0011】 なお遮蔽複合テープ11は上記の如くフラットケーブルの端部より突出し、か つ剥離した状態にせしめるものであるが、該突出し、かつ剥離させた遮蔽複合テ ープ部の長さについてはフラットケーブルの端部に取付ける機器例えばコネクタ の形状によって異るものであるため、これを限定することは出来ず、要は該機器 の表面を遮蔽複合テープにて十分に覆うような長さの突出部を設ければよく、通 常10〜15mmであり、これを夫々1/2で、フラットケーブルの両端に突出 かつ剥離させて配置すればよい。The shielding composite tape 11 is projected from the end of the flat cable as described above and is peeled off. The length of the protruding and peeling shielding composite tape is as follows. This cannot be limited because it depends on the shape of the device attached to the end of the flat cable, for example, the connector, and the point is that the protrusion of a length sufficient to cover the surface of the device with the shielding composite tape. It suffices to provide a portion, which is normally 10 to 15 mm, and it can be arranged by projecting and peeling it at both ends of the flat cable at both ends.
【0012】 又本考案遮蔽付フラットケーブル12において電磁波による遮蔽を有効に発揮 せしめるためには遮蔽複合テープの遮蔽金属層を接地することが最も好ましく、 その接地方法としてはフラットケーブルの接地の導体へ接続する方法或は遮蔽金 属層よりリード線を引出しプリント基盤の接地へ直接落す方法より行えばよい。Further, in order to effectively exhibit the shielding against electromagnetic waves in the shielded flat cable 12 of the present invention, it is most preferable to ground the shielding metal layer of the shielding composite tape. The grounding method is to the conductor of the flat cable grounding. The connection may be performed or the lead wire may be pulled out from the shielding metal layer and directly dropped to the ground of the printed circuit board.
