Description

【0001】
【発明の属する技術分野】
本発明は、分電盤にブレーカ等の電気機器を装着するための機器取り付けレールの固定方法に関する。
【0002】
【従来の技術】
図5〜図7に示すように、機器取り付けレール21には取り付け穴22が設けられており、従来、機器取り付けレール21を固定するには、機器取り付けレール21を必要な長さに予め切断し、機器取り付けレール21を取り付けるための固定穴(図示せず)を開口したパネル等に取り付け穴22と固定穴とにねじ23を挿通し締め付け固定していた。固定した機器取り付けレール21の任意の位置に固定金具24を取り付け、この固定金具24でブレーカ25等の電気機器の位置決めを行っていた。機器取り付けレール21は、その都度必要な長さに切断して使用するが、図8に示すように、L1、L2、L3のそれぞれの位置で切断した場合、取り付け穴22a、22b、22cは機器取り付けレール21の端部からの位置が変化し一定の位置ではない。そのため、機器取り付けレール21を固定するためのパネルに設ける固定穴も一定の位置に設定することができないので、これら不具合を解消するため、パネルに固定穴をたくさん設け、いずれかの固定穴が機器取り付けレール21の取り付け穴22に対向できるようにしていた。また、切断した機器取り付けレール21の取り付け穴22に合わせて、パネルにその都度後加工にて固定穴を開口していた。
【0003】
【発明が解決しようとする課題】
しかしながら、上記従来技術に示すように、たくさんの固定穴をパネルに設けるには、加工費がかかり、パネルの製作費のコストアップとなっていた。また、後加工にてパネルに固定穴を設けるには、加工時間が多くかかり、コストアップとなっていた。また、機器を固定するためにその都度固定金具24を取り付けなくてはならず、また、機器を固定するための壁状の金具が小さいため、機器が歪んだりしていた。
【0004】
【課題を解決するための手段】
そこで本発明は、簡単な構造で製造コストを抑えることのできる機器取り付けレールの固定方法を提供することを目的とし、その構造は、固定部と保持部とを形成したレール固定具の固定部で機器取り付けレールの両端を押さえ、レール固定具に設けられた螺子挿通孔に螺子を挿通し機器取り付けレールをレール固定具と共に固定し、レール固定具間にブレーカを並列しレール固定具の保持部でブレーカの側面を保持することを特徴とする。
【0005】
【発明の実施の形態】
本発明に係る機器取り付けレールの固定方法は、必要な長さに機器取り付けレールを切断し、その両端をレール固定具と共に、パネル等にねじ止めする。レール固定具は、固定部と保持部とで構成される。固定部は機器取り付けレールに対向する形状に形成し、保持部は壁状に上方へ向かって突設する。固定部には螺子挿通孔が設けられていて、固定部で機器取り付けレールの両端を固定しながら、ねじ止めする。レール固定具の間にブレーカ等の電気機器を配置し、保持部でブレーカの側面を保持し、機器の位置決めと固定を行うものである。
【0006】
【実施例】
本発明に係る機器取り付けレールの固定方法の実施例を図1〜図4の添付図面に基づいて説明する。
【0007】
分電盤の底面には、機器取り付けレールの幅に対向させて固定穴を設けたパネル等を取り付け、パネルに機器取り付けレール1をレール固定具2によって敷設する。ブレーカ3等の機器を機器取り付けレール1に取り付け、分電盤を構成する。
【0008】
機器取り付けレール1は、予め必要な長さに切断しておく。必要な長さは、ブレーカ3の幅寸法に個数を乗じた長さに機器取り付けレール1を固定する際に必要な長さを足したものである。
【0009】
レール固定具2は固定部2aと保持部2bとから構成され、固定部2aは機器取り付けレール1の形状に対向するように形成され、保持部2bは固定部2aから上方へ向かって壁状に突設させている。固定部2aには、固定用の螺子挿通孔4を形成している。機器取り付けレール1の両端部に、固定部2aを機器取り付けレール1に対向させて、機器取り付けレール1にはめ込むようにレール固定具2を取り付ける。固定部2aは螺子挿通孔4をパネル5に設けられた固定穴(図示せず)に対向させ、螺子挿通孔4と固定穴とにそれぞれ螺子6を挿通し、機器取り付けレール1と共にレール固定具2を固定する。ブレーカ3の取り付けは、レール固定具2の保持部2bで位置決めをしながら、保持部2b間に並べる。レール固定具2の保持部2bは、ブレーカ3の側面全体を保持するので、ブレーカ3が歪んだりすることがない。
【0010】
従来の機器取り付けレール1の固定方法に比べ、ねじ締め数が減るだけでなく、機器取り付けレール1に設けられている取り付け穴7は使用しなくてもよいため、適当な位置で機器取り付けレール1を切断し、取り付け穴7の位置に関係なくパネルに機器取り付けレール1を固定することができる。
【0011】
【発明の効果】
以上述べたように本発明に係る機器取り付けレールの固定方法は、固定部と保持部とを形成したレール固定具の固定部で機器取り付けレールの両端を押さえ、レール固定具に設けられた螺子挿通孔に螺子を挿通し機器取り付けレールをレール固定具と共に固定し、レール固定具間にブレーカを並列しレール固定具の保持部でブレーカの側面を保持するため、従来使用していた機器取り付けレールを取り付けるための固定穴を設けた高価なパネルなどの専用部品を使用する必要がなく、低コストで、パネルを製作することが可能となる。また、機器取り付けレールを取り付ける際に、その都度取り付けレールの取り付け穴に合わせてパネルに固定穴を加工する必要がないので、製作時間が短縮できる。さらには、機器取り付けレールは、従来のように現物を合わせながら切断しなくてもよいので、事前に準備でき、在庫化も可能になる。本発明のレール固定具は、確実に機器を保持、固定することができるので、機器取り付けの際または、輸送時の振動にも機器が傾かず、安定した製品を提供することができる。新たに固定金具を取り付ける必要もなく、確実に機器を保持することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for fixing a device mounting rail for mounting an electric device such as a breaker on a distribution board.
[0002]
[Prior art]
As shown in FIGS. 5 to 7, the device mounting rail 21 is provided with a mounting hole 22. Conventionally, in order to fix the device mounting rail 21, the device mounting rail 21 is cut in advance to a required length. In addition, a screw 23 is inserted through the mounting hole 22 and the fixing hole into a panel or the like in which a fixing hole (not shown) for mounting the device mounting rail 21 is opened, and tightened and fixed. A fixing bracket 24 is attached to an arbitrary position of the fixed device mounting rail 21, and an electric device such as a breaker 25 is positioned by the fixing bracket 24. The device mounting rail 21 is cut to a required length each time and used. However, as shown in FIG. 8, when the device mounting rail 21 is cut at the respective positions of L1, L2, and L3, the mounting holes 22a, 22b, and 22c are not used. The position from the end of the mounting rail 21 changes and is not a fixed position. For this reason, the fixing holes provided in the panel for fixing the device mounting rails 21 cannot be set at fixed positions. To solve these problems, a large number of fixing holes are provided in the panel. The mounting rail 21 can face the mounting hole 22. In addition, a fixing hole was formed in the panel by post-processing each time in accordance with the mounting hole 22 of the cut device mounting rail 21.
[0003]
[Problems to be solved by the invention]
However, as shown in the above-described prior art, providing a large number of fixing holes in a panel requires a processing cost, which increases the manufacturing cost of the panel. In addition, providing the fixing holes in the panel by post-processing requires a long processing time and increases the cost. In addition, in order to fix the device, the fixing bracket 24 must be attached each time, and since the wall-shaped metal fitting for fixing the device is small, the device is distorted.
[0004]
[Means for Solving the Problems]
Therefore, an object of the present invention is to provide a method for fixing an equipment mounting rail that can reduce manufacturing costs with a simple structure, and the structure is a fixing part of a rail fixing tool that forms a fixing part and a holding part. Hold both ends of the equipment mounting rail, insert screws into the screw insertion holes provided in the rail fixing tool, and fix the equipment mounting rail together with the rail fixing tool. It is characterized by holding the side of the breaker.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
In the method for fixing the equipment mounting rail according to the present invention, the equipment mounting rail is cut to a required length, and both ends thereof are screwed together with the rail fixing tool to a panel or the like. The rail fixing tool includes a fixing part and a holding part. The fixing portion is formed in a shape facing the device mounting rail, and the holding portion projects upward like a wall. The fixing portion is provided with a screw insertion hole, and is screwed while fixing both ends of the device mounting rail with the fixing portion. An electric device such as a breaker is disposed between the rail fixing devices, and the side of the breaker is held by a holding portion to position and fix the device.
[0006]
【Example】
An embodiment of a method for fixing a device mounting rail according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0007]
A panel or the like provided with a fixing hole is attached to the bottom of the distribution board so as to face the width of the device mounting rail, and the device mounting rail 1 is laid on the panel by the rail fixing device 2. A device such as a breaker 3 is mounted on the device mounting rail 1 to form a distribution board.
[0008]
The equipment mounting rail 1 is previously cut to a required length. The required length is obtained by adding the length required for fixing the equipment mounting rail 1 to the length obtained by multiplying the width of the breaker 3 by the number.
[0009]
The rail fixing device 2 includes a fixing portion 2a and a holding portion 2b. The fixing portion 2a is formed so as to face the shape of the device mounting rail 1, and the holding portion 2b is formed in a wall shape upward from the fixing portion 2a. They are protruding. A fixing screw insertion hole 4 is formed in the fixing portion 2a. At both ends of the equipment mounting rail 1, the fixing parts 2 a are opposed to the equipment mounting rail 1, and the rail fixing tools 2 are mounted so as to fit into the equipment mounting rail 1. The fixing portion 2a makes the screw insertion hole 4 face a fixing hole (not shown) provided in the panel 5, inserts the screw 6 into each of the screw insertion hole 4 and the fixing hole, and the rail fixing tool together with the equipment mounting rail 1. Fix 2 The breakers 3 are arranged between the holding portions 2b while being positioned by the holding portions 2b of the rail fixing tool 2. Since the holding portion 2b of the rail fixing member 2 holds the entire side surface of the breaker 3, the breaker 3 does not become distorted.
[0010]
Compared with the conventional method of fixing the equipment mounting rail 1, not only the number of screws to be tightened is reduced, but also the mounting hole 7 provided in the equipment mounting rail 1 does not need to be used. And the device mounting rail 1 can be fixed to the panel regardless of the position of the mounting hole 7.
[0011]
【The invention's effect】
As described above, the fixing method of the equipment mounting rail according to the present invention includes the fixing part of the rail fixing tool having the fixing part and the holding part, which presses both ends of the equipment mounting rail and inserts the screw provided on the rail fixing tool. Insert a screw into the hole to fix the equipment mounting rail together with the rail fixing tool, place a breaker between the rail fixing tools, and hold the side of the breaker with the holding part of the rail fixing tool. It is not necessary to use a dedicated component such as an expensive panel provided with a fixing hole for mounting, and the panel can be manufactured at low cost. In addition, when mounting the equipment mounting rail, it is not necessary to machine the fixing hole in the panel in accordance with the mounting hole of the mounting rail each time, so that the manufacturing time can be reduced. Furthermore, since the equipment mounting rail does not have to be cut while matching the actual product as in the related art, it can be prepared in advance and can be stocked. Since the rail fixing device of the present invention can securely hold and fix the device, the device does not tilt even when the device is attached or is vibrated during transportation, and a stable product can be provided. The device can be securely held without the need to attach a new fixture.
