Description
本考案は、情報処理機器などの操作部に用いられるパネルスイッチのフレーム 構造の改良に関するものである。 The present invention relates to an improvement in a frame structure of a panel switch used in an operation unit of an information processing device or the like.
図5は従来のパネルスイッチのフレーム構造を示したものである。フレーム1 は例えばABS樹脂等の合成樹脂材によって成形され、その板面にはキー操作用 の透孔に対応するように、複数(図では1個のみ示している)の円形状の落し込 み部11が配設されている。即ち、フレーム1に落し込み部11を形成するため 、図においては4個の長孔12が落し込み部11の外周に沿うようにして等間隔 に設けられている。これにより、隣接した長孔12間には、フレーム1と落し込 み部11とを接続する連結部13が形成される。次に、この様なフレーム1を用 いて図6に示すパネルスイッチ3を組み立てるには、先ず、基板2に配設された 例えばタクトスイッチ21に対応した位置にある落し込み部11が除去される。 その場合、連結部13をニッパ等の工具を用いて、切断することによって落し込 み部11が除去され、フレーム1に透孔14が形成される。次いで、フレーム1 の上面には、例えばポリエステル等のシート31が接着される。その後、フレー ム1の透孔14内にタクトスイッチ21のキートップ21a部分を挿入して、シ ート31の裏面にキートップ21aを接触させた状態でフレーム1に基板2を取 り付ける。これにより、パネルスイッチ3はシート31を介してキートップ21 aを押圧し、タクトスイッチ21のスイッチング動作が行なわれる。 FIG. 5 shows a frame structure of a conventional panel switch. The frame 1 is made of, for example, a synthetic resin material such as ABS resin, and a plurality of (only one is shown in the figure) circular recesses are formed on the plate surface so as to correspond to the through holes for key operation. The part 11 is provided. That is, in order to form the depressions 11 in the frame 1, four elongated holes 12 are provided at equal intervals along the outer circumference of the depressions 11 in the figure. As a result, a connecting portion 13 that connects the frame 1 and the drop portion 11 is formed between the adjacent elongated holes 12. Next, in order to assemble the panel switch 3 shown in FIG. 6 using the frame 1 as described above, first, the recessed portion 11 provided on the substrate 2 at a position corresponding to the tact switch 21, for example, is removed. . In that case, the drop portion 11 is removed by cutting the connecting portion 13 with a tool such as a nipper, and the through hole 14 is formed in the frame 1. Next, a sheet 31 made of polyester or the like is adhered to the upper surface of the frame 1. After that, the key top 21a portion of the tact switch 21 is inserted into the through hole 14 of the frame 1, and the substrate 2 is attached to the frame 1 with the key top 21a in contact with the back surface of the sheet 31. As a result, the panel switch 3 presses the key top 21 a via the seat 31, and the tact switch 21 is switched.
ところで、上述したフレーム構造では、パネルスイッチ3が組み込まれる情報 機器等のキー配列に応じて落し込み部11を除去し、透孔14が設けられるが、 透孔14の不要な箇所の落し込み部11はフレーム1に残されたまま、その上に シート31が張られる。この場合、押圧力がシート31上から落し込み部11に 対し不用意に加えられると、連結部13が破断して落し込み部11をフレーム1 から脱落させる恐れがあった。これを防ぐため、従来は連結部13の肉厚をフレ ーム1と同様に厚くしていたが、連結部13の肉厚が厚くなると、連結部13の 切断作業を困難にした。更には、連結部13を切断した後、透孔14の内周面に 連結部13の切り残し部分が残っていると、キー操作の際、タクトスイッチ21 のキートップ21aに引っ掛かる恐れがある為、その仕上作業を行なう必要もあ り、甚だ作業性が悪かった。それ故に、本考案は上述したような欠点を解決する 為になされたものであり、落し込み部の除去作業を容易にすると共に、押圧力に 対し落し込み部の脱落を防止したパネルスイッチのフレーム構造を提供する。 By the way, in the frame structure described above, the recessed portion 11 is removed and the through hole 14 is provided according to the key arrangement of the information device or the like in which the panel switch 3 is incorporated, but the recessed portion of the unnecessary portion of the through hole 14 is provided. The sheet 11 is left on the frame 1 and the sheet 31 is stretched thereon. In this case, if a pressing force is inadvertently applied to the drop-in portion 11 from above the sheet 31, the connecting portion 13 may be broken and the drop-in portion 11 may be dropped from the frame 1. In order to prevent this, the wall thickness of the connecting portion 13 has conventionally been made thick like the frame 1, but when the wall thickness of the connecting portion 13 becomes thick, the cutting work of the connecting portion 13 becomes difficult. Furthermore, if the uncut portion of the connecting portion 13 remains on the inner peripheral surface of the through hole 14 after the connecting portion 13 is cut, the key top 21a of the tact switch 21 may be caught during key operation. However, the finishing work had to be done, and the workability was extremely poor. Therefore, the present invention has been made in order to solve the above-mentioned drawbacks, and facilitates the work of removing the drop-in portion and prevents the drop-out portion from falling off against the pressing force. Provide structure.
本考案は、フレームのパネル面に切り離し可能な落し込み部を配設し、上記落 し込み部を切り離し除去することによって電気部品が挿入される透孔を設けるパ ネルスイッチのフレーム構造において、上記透孔の内周面に切欠部を設け、上記 切欠部から上記透孔側へ突出する連結部の先端に、上記落し込み部を接続すると 共に、上記落し込み部は下面に上記フレームに対向配置されたパネルスイッチ固 定部に当接する支持部を突設したものである。以上の如く構成されたフレーム構 造では上記落し込み部に押圧力が加えられた際、上記支持部によって上記フレー ムより上記落し込み部の脱落を防ぐことができる。更には、押圧力が上記支持部 と連結部とに分散して加わるため、連結部の肉厚が従来よりも薄くでき、落し込 み部の除去作業を容易にするパネルスイッチのフレーム構造が得られる。 The present invention provides the frame structure of a panel switch, wherein a detachable drop portion is provided on a panel surface of a frame, and a through hole for inserting an electrical component is provided by cutting and removing the drop portion. A notch is provided on the inner peripheral surface of the through hole, and the drop part is connected to the tip of the connecting part protruding from the notch to the through hole side, and the drop part is arranged on the lower surface so as to face the frame. The supporting portion is provided so as to abut the fixed panel switch fixing portion. In the frame structure configured as described above, when the pressing force is applied to the dropping portion, the supporting portion can prevent the dropping portion from falling out of the frame. Furthermore, since the pressing force is distributed and applied to the supporting part and the connecting part, the wall thickness of the connecting part can be made thinner than before, and a panel switch frame structure that facilitates the removal work of the dropped part is obtained. To be
以下、本考案の実施例について図1乃至図4を参照しつつ説明する。図1(a )にフレームの平面図、同図(b)にその側断面図を示す。フレーム4には、例 えばタクトスイッチ等のキー配列に対応し得るように円形状の落し込み部41が 複数(図では1個のみ示している。)設けられる。即ち、フレーム4に落し込み 部41を設ける為、図に示す如く環状の溝部42が形成されている。その溝部4 2を構成する内側面42aは落し込み部41の外周面となり、又、溝部42の外 側面42bは落し込み部41を除去することによって形成される透孔の内周面に なる。 溝部42の外側面42bには、切欠部43,43が互いに180°離間して対 向する箇所に設けられている。その切欠部43,43の底壁面43aの下端側か らは、フレーム4の板厚よりも薄い連結部44,44が突出され、連結部44, 44の先端間に落し込み部41を一体に接続している。落し込み部41の下面中 央には、ボス又はリブとなる支持部41aが対向配置される基板に向けて突設さ れている。 次に、図3に示す如く本考案のフレーム4を用いてパネルスイッチ5を組み立 てるには、先ず、フレーム4に配設された落し込み部41のうち、基板2に配列 されたタクトスイッチ21に対応した位置にある落し込み部41のみフレーム4 から除去する。 即ち、落し込み部41の上面を手指により押圧して連結部44を破断すること で、図2に示す如く透孔45があけられる。次いで、フレーム4の上面にシート 46を接着した後、基板2が透孔45内にタクトスイッチ21のキートップ21 aを挿入し、シート46の裏面にキートップ21aを接触させた状態でフレーム 4に取り付けられる。図3(b)は落し込み部41が除去されていない箇所のフ レーム4を示したものであり、その場合にはフレーム4が支持部41aを基板2 に当接させて組み立てられる。この為、押圧力がシート46上から落し込み部4 1に加えられた際は、押圧力が連結部44と支持部41aとに分散して加わる為 、連結部44の肉厚を従来例に比べて薄くできる。これにより、連結部44の切 断作業は容易になり作業性が向上する。又、落し込み部41を除去した後、連結 部44の切り残し部44aが図2に示す如く透孔45内に突出せず切欠部43内 にある為、スイッチング操作の際はタクトスイッチ21のキートップ21aに引 っ掛かる恐れがない。更には、連結部44が切欠部43の下端から突出している ためシート46に当接することもない。この様に連結部44が切欠部43内にあ る為、連結部44の切断後の仕上作業を省くことも可能になる。図4は本考案の フレームを使用したパネルスイッチの他の実施例であり、同図(a)ではエンボ スシート61を使用したパネルスイッチ6を示している。又、同図(b)のパネ ルスイッチ7はシート71に透孔71aを設け、タクトスイッチ21のキートッ プ21aを透孔71aから突出させたものを示している。 尚、上記実施例では落し込み部41の形状を円形にしたが、これに限定されず 種々の形状に設計変更できる。 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1A shows a plan view of the frame, and FIG. 1B shows a side sectional view thereof. The frame 4 is provided with a plurality of circular recesses 41 (only one is shown in the figure) so as to correspond to a key arrangement such as a tact switch. That is, since the recessed portion 41 is provided on the frame 4, an annular groove portion 42 is formed as shown in the drawing. The inner side surface 42a forming the groove portion 42 serves as the outer peripheral surface of the recessed portion 41, and the outer side surface 42b of the groove portion 42 serves as the inner peripheral surface of the through hole formed by removing the recessed portion 41. On the outer side surface 42b of the groove portion 42, notch portions 43, 43 are provided at positions facing each other by 180 ° apart from each other. From the lower end side of the bottom wall surface 43a of the cutouts 43, 43, the connecting portions 44, 44 which are thinner than the plate thickness of the frame 4 are projected, and the recess 41 is integrally formed between the tips of the connecting portions 44, 44. Connected. In the center of the lower surface of the drop-in portion 41, a support portion 41a, which serves as a boss or a rib, is provided so as to project toward the substrate that is arranged to face it. Next, as shown in FIG. 3, in order to assemble the panel switch 5 using the frame 4 of the present invention, first of all, the tact switch 21 arranged on the substrate 2 in the recess 41 arranged in the frame 4. Only the recessed portion 41 at the position corresponding to is removed from the frame 4. That is, by pressing the upper surface of the drop portion 41 with fingers to break the connecting portion 44, the through hole 45 is opened as shown in FIG. Next, after the sheet 46 is adhered to the upper surface of the frame 4, the board 2 inserts the key top 21 a of the tact switch 21 into the through hole 45, and the key top 21 a is brought into contact with the back surface of the sheet 46. Attached to. FIG. 3 (b) shows the frame 4 where the recessed portion 41 is not removed. In this case, the frame 4 is assembled by bringing the support portion 41a into contact with the substrate 2. Therefore, when the pressing force is applied from the top of the sheet 46 to the drop portion 41, the pressing force is dispersedly applied to the connecting portion 44 and the supporting portion 41a, and the wall thickness of the connecting portion 44 is the same as that of the conventional example. Can be made thinner than in comparison. This facilitates the cutting work of the connecting portion 44 and improves workability. Further, after the drop-in portion 41 is removed, the uncut portion 44a of the connecting portion 44 does not project into the through hole 45 and is inside the cutout portion 43 as shown in FIG. There is no danger of getting caught on the key top 21a. Further, since the connecting portion 44 projects from the lower end of the cutout portion 43, it does not come into contact with the seat 46. Since the connecting portion 44 is in the cutout portion 43 in this manner, it is possible to omit the finishing work after cutting the connecting portion 44. FIG. 4 shows another embodiment of the panel switch using the frame of the present invention, and FIG. 4A shows the panel switch 6 using the embossed sheet 61. Further, the panel switch 7 of FIG. 2B shows a sheet 71 having a through hole 71a, and the key top 21a of the tact switch 21 protruding from the through hole 71a. Although the recess 41 has a circular shape in the above-described embodiment, the shape is not limited to this and the design can be changed to various shapes.
