Description
【０００１】[0001]
本考案は、分電盤のレール取り付け機構の改良に関するものである。 The present invention relates to improvement of a rail mounting mechanism of a distribution board.
【０００２】[0002]
従来、分電盤のレール取り付け機構としては各種のものがあり、最も一般的な ものは、レールの両端部をボックスにボルト止めしただけのものであった。しか し、ボックスの縦寸法が１２００ｍｍ以上に長くなると、レール長も長くなり、 両端の固定のみでは中央部の強度が不足し、分電盤に何等かの衝撃が加わるとレ ールに振動が発生し、レールに機器取り付け板を介して取り付けられているブレ ーカのハンドルが破損する等内部電気機器へ悪影響を及ぼすことがあった。その ため、レールの中間部のレール取り付け金具を利用して補強したり、或は図４示 の補強枠体１０をレール１の中間部内側に装着してレール１にねじ止めすること が行われていた。 Conventionally, there are various types of rail mounting mechanisms for a distribution board, and the most common type is one in which both ends of the rail are simply bolted to a box. However, if the vertical dimension of the box becomes longer than 1200 mm, the rail length will become longer, and the strength of the center part will be insufficient if both ends are fixed, and if some shock is applied to the distribution board, the rail will vibrate. Occurrences could occur, which could adversely affect internal electrical equipment, such as damage to the handle of the breaker attached to the rail via the equipment mounting plate. Therefore, reinforcement is performed by using a rail mounting bracket in the middle of the rail, or the reinforcement frame 10 shown in FIG. 4 is mounted inside the middle of the rail 1 and screwed to the rail 1. Was there.
【０００３】 また、実開昭６４−５０６１１号公報には、フレームをボックスにボルト止め するボルトの挿通孔と、フレームの両下端が載置される載置片と、フレームの外 側に位置する固定片とからなり、フレームの長手方向に所定の長さを有する中間 固定板を、ボックスに挿通孔を介してボルト止めし、この中間固定板の固定片に 固定具を設け、取り付け板をこの固定具を介してフレームにねじ止めして成るも のが開示されていた。Further, in Japanese Utility Model Laid-Open No. 64-50611, a bolt insertion hole for bolting the frame to the box, a mounting piece on which both lower ends of the frame are mounted, and a mounting piece located on the outer side of the frame. An intermediate fixing plate consisting of a fixing piece and having a predetermined length in the longitudinal direction of the frame is bolted to the box through the insertion hole, and the fixing piece is provided on the fixing piece of this intermediate fixing plate. It has been disclosed that it is screwed to the frame via a fixing tool.
【０００４】[0004]
上記従来の分電盤のレール取り付け機構において、ボックスの縦寸法が長く、 レールの中間部のレール取り付け金具を利用して補強したものは、そのレール取 り付け金具を固定するボルトナットに、機器取り付け板のボルトが重なることが あって、機器取り付け板の取り付けが制約されるので実用的でなかった。また、 図４示のように、補強枠体２０をレール１の中間部内側に装着してレール１にネ ジ止めしたものは、レール１の落ち込み防止には有効であるが、補強枠体２０が ボックスに固定されていないため、補強が不十分でレール１に振動が発生し易く 、また、外部衝撃に弱く、ブレーカ等の内部電気機器や扉等を損傷させることが あった。 In the above-mentioned conventional rail mounting mechanism for the distribution board, the vertical dimension of the box is long and reinforced by using the rail mounting metal fitting in the middle of the rail. This was not practical because the bolts on the mounting plate could overlap, which constrains the mounting of the device mounting plate. Further, as shown in FIG. 4, the reinforcement frame 20 mounted inside the middle part of the rail 1 and fixed to the rail 1 by a screw is effective for preventing the rail 1 from falling, but the reinforcement frame 20 Since it is not fixed to the box, the reinforcement is insufficient and vibration is likely to occur in the rail 1, and it is vulnerable to external impacts, which may damage internal electrical equipment such as breakers and doors.
【０００５】 そして、実開昭６４−５０６１１号公報に記載のものは、フレームの長手方向 に所定の長さを有する中間固定板をボックスにボルト止めし、その中間固定板に フレームと取り付け板とを固定具によってねじ止めして、中間固定板をフレーム の中間部に設けるものの、フレームは、ボックスにボルト止めした中間固定板に 直接固着されておらず、固定具を介して固着されていること、及びフレームが中 間固定板の載置片に載置されボックス面から離れた位置に設けられていることか らして、耐振動性の点で問題があり、更に部品点数が多く、且つ固定具とフレー ムと取り付け板との位置合わせをしてねじ止めする作業が面倒である等の欠点を 有していた。In Japanese Utility Model Application Laid-Open No. 64-50611, an intermediate fixing plate having a predetermined length in the longitudinal direction of the frame is bolted to a box, and the intermediate fixing plate is provided with a frame and a mounting plate. The intermediate fixing plate is attached to the middle part of the frame by screwing it with a fixing tool, but the frame is not fixed directly to the intermediate fixing plate bolted to the box, but it is fixed via the fixing tool. Since the frame is mounted on the mounting plate of the intermediate fixing plate and is located away from the box surface, there is a problem in terms of vibration resistance, and the number of parts is large and the frame is fixed. There was a drawback that the work of aligning the tool, frame and mounting plate and screwing them was troublesome.

Each rail 1 is provided with bolt insertion holes 1a at both ends thereof, and a plurality of mounting holes 1b of equipment mounting plates (not shown) are provided on the surface thereof at regular intervals, and rail mounting brackets 2 to be described later are provided at both end side plates. A notch 1c is provided to be locked by.
【００１０】 また、２はボックス本体（図示省略）内に設けられその中央部に断面コ字状の 突設部２ａを形成したレール取り付け金具であって、後述するレール固定金具 を構成するものであり、その突設部２ａの表面にボルト３の頭部挿入孔２ｂとそ れに隣接する頭部係止孔２ｃとを備え、レール１の切欠部１ｃに挿入可能に、且 つレール１の両端開口部に装着可能に形成されている。このレール取り付け金具 ２にレール１の端部を取り付けるには、ボルト３を頭部挿入孔２ｂから挿入して 横にスライドさせ、ボルト３の頭部を頭部係止孔２ｃに係止する。そしてレール １の切欠部１ｃをレール取り付け金具２の突設部２ａに係止させるようにして、 その開口部をレール取り付け金具２に押入嵌着し、ボルト挿通孔１ａに挿通した ボルト３をナット４、４で締付固定する。Reference numeral 2 denotes a rail mounting metal fitting provided in a box main body (not shown) and having a projecting portion 2a having a U-shaped cross section formed in the central portion thereof, which constitutes a rail fixing metal fitting described later.

In addition, the rail fixing tool 7 is fitted from the other opening of the rail mounting tool 2 so that the end of the fixing tool 6 and one end of the rail fixing tool 7 overlap inside the rail mounting tool 2. To do. Further, the other end of the rail fixing tool 7 is locked in a locking groove 1f provided on the side surface of the rail 1, and a screw insertion hole 8a provided in the reinforcing metal fitting 8 is provided on the rail surface so as to maintain this state. It is tightened and fixed by the screw 10 in conformity with the stopper hole 1e.
