Description
この発明は、筐体等の開口部に取り付けて、フラットケーブルを筐体等に引き込んだ状態で固定するための保護固定具に関するものである。
The present invention relates to a protective fixture for fixing a flat cable attached to an opening of a housing or the like while being pulled into the housing or the like.
筐体に設けられた開口部からケーブルを引き込むまたは引き出す構造において、開口部のエッジによりケーブルが傷付いたり断線したりすることを防ぐために、従来は、エッジに面打ち加工または曲げ加工等の傷付き防止加工を施すか、別部品でエッジを覆う必要があった。
Conventionally, in order to prevent the cable from being damaged or disconnected by the edge of the opening in the structure in which the cable is pulled in or pulled out from the opening provided in the housing, conventionally, the edge has been subjected to scratches such as beveling or bending. It was necessary to apply anti-stick processing or cover the edge with a separate part.
さらに、筐体開口部からの異物の侵入防止および意匠向上を目的として、開口部を閉塞するための樹脂製の蓋を取り付ける必要があった。例えば特許文献1には、薄い樹脂板の中央部にケーブル束を挿通する開口を設けた樹脂部品が提案されている。この樹脂部品は、筐体開口部を覆うようにねじ止めされ、開口からケーブル束を引き込むことにより、筐体内への異物の侵入を防止していた。
Furthermore, it was necessary to attach a resin lid for closing the opening for the purpose of preventing entry of foreign matter from the opening of the housing and improving the design. For example, Patent Document 1 proposes a resin component in which an opening through which a cable bundle is inserted is provided at the center of a thin resin plate. The resin component is screwed so as to cover the housing opening, and a cable bundle is drawn from the opening to prevent foreign matter from entering the housing.
従来のケーブル引き込み構造は以上のように構成されているので、エッジの傷付き防止加工は、金型構造の複雑化および作業工程数の増加につながり、金型製作時の費用増大および作業工賃増大といったコスト的問題と、傷付き防止加工の加工漏れ、加工不十分および加工カスの発生等の二次弊害といった品質的問題とが発生してしまう課題があった。
また、開口部のエッジを別部品で覆う場合には、開口部の裏表どちらか一方からの嵌合となるため、完全にエッジを覆ってケーブルを保護することは困難であった。
さらに、開口部を樹脂部品で閉塞する場合には、樹脂部品を筐体にねじ止めするため、構成部品の増加につながり、コスト増大の一因となってしまった。 Since the conventional cable lead-in structure is configured as described above, edge damage prevention processing leads to a complicated mold structure and an increase in the number of work processes, which increases the cost for manufacturing the mold and increases the work cost. There are problems such as cost problems such as the above, and quality problems such as secondary defects such as processing omission of damage prevention processing, insufficient processing, and generation of processing residue.
Further, when the edge of the opening is covered with a separate part, the fitting is performed from either the front or back of the opening, and thus it is difficult to completely cover the edge and protect the cable.
Furthermore, when the opening is closed with a resin component, the resin component is screwed to the housing, which leads to an increase in the number of components and contributes to an increase in cost.

By inserting the flat cable hole 15 into the fixed claw 5 of the upper lid 1, the fixed claw 5 can temporarily hold the flat cable 14 a. For this reason, useless play of the flat cable 14a in the middle of work is suppressed, and it becomes possible to prevent damage and disconnection and to improve workability.
Further, by holding theflat cable 14a between the upper lid 1 and the lower lid 2 while the flat cable hole 15 is inserted into the fixing claw 5, the protective fixture can more firmly fix the flat cable 14a.
In addition, you may make a hole directly in theflat cable 14a, without providing an ear shape. Further, the fixing claw 5 may not be used as the holding portion of the flat cable 14a, and the holding portion may be provided at an arbitrary position of the upper lid 1 or the lower lid 2.
フラットケーブル14aには耳形状が設けられ、そこにフラットケーブル穴15が穿設されている。フラットケーブル穴15を上蓋1の固定爪5に挿通することで、固定爪5がフラットケーブル14aを仮保持しておくことができる。このため、作業途中のフラットケーブル14aの無駄な遊びが押さえられ、傷付きおよび断線の防止ならびに作業性の向上が可能となる。
また、フラットケーブル穴15を固定爪5に挿通したままでフラットケーブル14aを上蓋1と下蓋2で挟み込むことにより、保護固定具はフラットケーブル14aをより強固に固定することができる。
