JP 2001-145216 A

しかしながら、上記従来技術における充電部保護カバー３１の取り付け構造では、充電部保護カバー３１は充電部支持台３２に引っ掛けられているだけで固定されていないので、輸送時の振動や、人が不意に触れた場合に、充電部保護カバー３１が外れてしまう虞があり、取り扱いに注意が必要であった。また、充電部支持台３２の位置にしか充電部保護カバー３１が取り付けられないため、例えば、主幹ブレーカ３５と主幹導電バー３６が同一直線上にない場合には、充電部を保護することができなかった。   However, in the mounting structure of the charging unit protection cover 31 in the above-described prior art, the charging unit protection cover 31 is only fixed to the charging unit support base 32 and is not fixed. When it touches, there exists a possibility that the charging part protective cover 31 may remove | deviate, and attention was required for handling. In addition, since the charging unit protection cover 31 is attached only at the position of the charging unit support base 32, for example, when the main breaker 35 and the main conductive bar 36 are not on the same straight line, the charging unit can be protected. There wasn't.

そこで本発明は、簡単な構造で、安価な分電盤の充電部保護カバーを提供することを目的とし、その構造は、導電バー上に取り付け可能である固定台と、ブレーカの端子を被覆する端子カバーに設けられた固定穴とにより充電部保護カバーを固定可能とし、充電部を施蓋することを特徴とする。   Therefore, the present invention has an object to provide a chargeable part protective cover for a distribution board that has a simple structure and is inexpensive, and the structure covers a fixed base that can be mounted on a conductive bar and a terminal of a breaker. The charging part protective cover can be fixed by a fixing hole provided in the terminal cover, and the charging part is covered.

本発明に係る充電部保護カバーは、導電バー上に取り付け可能である固定台と、ブレーカの端子を被覆する端子カバーに設けられた固定穴とにより、充電部保護カバーで充電部を施蓋するため、簡単な部品で構成できることにより安価に充電部保護カバーが提供できる。また、充電部保護カバーは取り付けに必要な部品も少なく、取り付け作業も容易に行える。端子カバーを用いて充電部保護カバーが取り付けられるため、主幹ブレーカと主幹導電バーが同一直線上にない場合でも、主幹導電バーと接続導電バーとの高さが異なる場合でも、同じ充電部保護カバーで充電部を施蓋することができる。   The charging unit protective cover according to the present invention covers the charging unit with the charging unit protective cover by a fixing base that can be mounted on the conductive bar and a fixing hole provided in the terminal cover that covers the terminal of the breaker. For this reason, the charging part protective cover can be provided at low cost by being configured with simple parts. In addition, the charging part protective cover requires few parts and can be easily attached. Since the live part protective cover is attached using the terminal cover, the same live part protective cover is used even when the main breaker and main conductive bar are not on the same straight line, or when the main conductive bar and connection conductive bar are different in height. The charging part can be covered with.

本発明に係る分電盤の充電部保護カバーの実施例を図１〜図３の添付図面に基づいて説明する。   An embodiment of a charging part protective cover for a distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.

分電盤１は、主幹ブレーカ２や分岐ブレーカ３等の電気機器を配列し、これら電気機器間は導電バーや電線で接続し、この接続部分は充電部と呼ばれている。通電中に誤って触れると感電事故を起こしたりする虞があるため、充電部の上部は充電部保護カバー４で施蓋する。電気機器の配列は、通常、主幹ブレーカを中央部に配置し、主幹ブレーカの直下に主幹導電バーを接続して主幹導電バーの左右に分岐ブレーカを配置することが多い。しかし、送り回路やタイムスイッチ等のを配置したい場合、分電盤１は省スペースで収めたいため、主幹ブレーカ２の直下に主幹導電バー５を配列せず、主幹ブレーカ２をどちらかに寄せて、分電盤１の中央部に配置される主幹導電バー５に接続導電バー６を介して接続することもある。   The distribution board 1 arranges electric devices such as a main breaker 2 and a branch breaker 3, and these electric devices are connected by a conductive bar or electric wire, and this connection portion is called a charging unit. If there is a risk of an electric shock if touched accidentally during energization, the upper part of the charging part is covered with the charging part protective cover 4. In the arrangement of electrical devices, usually, a main breaker is arranged at the center, a main conductive bar is connected directly below the main breaker, and branch breakers are arranged on the left and right sides of the main conductive bar. However, when it is desired to arrange a feed circuit, a time switch, etc., the distribution board 1 needs to be saved in a space-saving manner. The main conductive bar 5 arranged in the center of the distribution board 1 may be connected via the connection conductive bar 6.

主幹ブレーカ２の端子部２ａには端子カバー７を取り付け、端子部２ａを保護する。この端子カバー７の前面端部には固定穴７ａを設ける。   A terminal cover 7 is attached to the terminal portion 2a of the main breaker 2 to protect the terminal portion 2a. A fixing hole 7 a is provided at the front end of the terminal cover 7.

また、主幹導電バー５上には、分岐導電バー８を接続するための接続穴９に取り付け可能である固定台１０が設置可能である。固定台１０は、主幹導電バー５の幅寸法に対向する溝１０ａを有し、主幹導電バー５に固定する螺子挿通孔１０ｂと、充電部保護カバー４を固定するためのねじ穴１０ｃとを形成している。主幹導電バー５上に固定台１０を、溝１０ａを主幹導電バー５に対向させ螺子挿通孔１０ｂと、主幹導電バー５の接続穴９とにそれぞれ固定ねじ１１を挿通し締め付け固定する。   On the main conductive bar 5, a fixing base 10 that can be attached to a connection hole 9 for connecting the branch conductive bar 8 can be installed. The fixing base 10 has a groove 10a opposite to the width of the main conductive bar 5 and forms a screw insertion hole 10b for fixing the main conductive bar 5 and a screw hole 10c for fixing the charging unit protective cover 4. is doing. The fixing base 10 is fixed on the main conductive bar 5, and the fixing screw 11 is inserted into the screw insertion hole 10 b and the connection hole 9 of the main conductive bar 5 with the groove 10 a facing the main conductive bar 5 and fastened and fixed.

主幹ブレーカ２と分岐ブレーカ３は一直線状にない場合でも、接続導電バー６と主幹導電バー５とで構成される充電部に合わせて略Ｌ字状の充電部保護カバー４を形成する。充電部保護カバー４には、端子カバー７に設けられた固定穴７ａと、固定台１０に設けられたねじ穴１０ｃとにそれぞれ対向する位置に取り付け穴４ａを設ける。充電部に充電部保護カバー４を載せ、取り付け穴４ａと固定穴７ａ、取り付け穴４ａとねじ穴１０ｃとにそれぞれねじ１２を挿通し、充電部保護カバー４を取り付ける。   Even when the main breaker 2 and the branch breaker 3 are not in a straight line, a substantially L-shaped charging portion protective cover 4 is formed in accordance with the charging portion constituted by the connection conductive bar 6 and the main conductive bar 5. The charging unit protective cover 4 is provided with attachment holes 4a at positions facing the fixing hole 7a provided in the terminal cover 7 and the screw hole 10c provided in the fixing base 10, respectively. The charging unit protective cover 4 is placed on the charging unit, and the charging unit protective cover 4 is mounted by inserting the screws 12 through the mounting hole 4a and the fixing hole 7a, and the mounting hole 4a and the screw hole 10c, respectively.

主幹ブレーカの端子部に取り付けられる端子カバーと、主幹導電バーに取り付けられた固定台とで支持されるため、接続導電バーと主幹導電バーとの配列高さが異なっていても、固定台の寸法で調節が可能であり、充電部保護カバーが取り付け可能である。   Because it is supported by the terminal cover attached to the terminal part of the main breaker and the fixed base attached to the main conductive bar, the dimensions of the fixed base even if the connection conductive bar and main conductive bar have different arrangement heights Adjustment is possible, and a charging part protective cover can be attached.

固定台１０の、充電部保護カバー４に対向する面に、突起１０ｄを設ける。充電部保護カバー４の、突起１０ｄに対向する位置に突起穴４ｂを形成すると、充電部保護カバー４を取り付けるときに、その取り付け位置の決定がしやすくなる。   A protrusion 10 d is provided on the surface of the fixing base 10 that faces the charging unit protective cover 4. When the projection hole 4b is formed at a position of the charging unit protection cover 4 facing the projection 10d, the mounting position of the charging unit protection cover 4 can be easily determined when the charging unit protection cover 4 is installed.

充電部保護カバー４は、施蓋する充電部の形状に合わせて適宜変更する。例えば、図１に示すように、主幹ブレーカ２から直線的に主幹導電バー５が接続されず、左右にずれた位置に配置されている場合には、接続導電バー６と主幹導電バー５とを施蓋できるように、略Ｌ字状に形成された充電部保護カバー４を用いる。また、主幹ブレーカから直線状に主幹導電バーが接続されている場合には、直線形状の充電部保護カバーを用いる。   The charging unit protective cover 4 is appropriately changed according to the shape of the charging unit to be covered. For example, as shown in FIG. 1, when the main conductive bar 5 is not connected linearly from the main breaker 2 and is arranged at a position shifted left and right, the connection conductive bar 6 and the main conductive bar 5 are connected to each other. The charging part protective cover 4 formed in a substantially L shape is used so that the lid can be applied. Further, when the main conductive bar is connected in a straight line from the main breaker, a linear charging portion protective cover is used.

また、充電部保護カバーはねじ止めされるため、振動や不意に接触してしまったときの衝撃などによる脱落が回避でき、安全であり、容易に取り付けられる。   In addition, since the live part protection cover is screwed, it can be prevented from falling off due to vibration or shock when it comes into contact unexpectedly, and is safe and easily attached.

充電部保護カバーで充電部を保護し、さらにその上から配線覆いで被覆することも可能で、配線覆いを開放した状態での分電盤の点検や確認の際に誤って作業者が充電部に触れてしまうことを避けることができる。   It is also possible to protect the live part with the live part protective cover, and to cover it with a wiring cover from above, so that an operator may accidentally check the power distribution panel with the wiring cover open. You can avoid touching.
