Description
【０００１】[0001]
本考案はニュートラル端子を主幹用母線の末端に集合配置した分電盤に関する ものである。 The present invention relates to a distribution board in which neutral terminals are collectively arranged at the end of a main bus for a main trunk.
【０００２】[0002]
従来、この種の分電盤においては、ニュートラル端子を操作するときに手指が 主幹用母線や分岐用導電バー等に誤って触れるのを防止するため、ニュートラル 端子と主幹用母線との間に保護板を立設してある。このような保護板21は、図５ に示すようにその下端に折曲形成した取付板部22をタッピンねじ23により中性極 用ベース24に取付けたものが普通である。 ところがこのような従来のものにあっては、取付板部22を製造するためにプレ スによる抜き加工をしたうえで更に折り曲げ加工を必要とし、またタッピンねじ 23により取付けていたので、取付工程が面倒であった。 Conventionally, in this type of distribution board, when operating the neutral terminal, in order to prevent the fingers from accidentally touching the trunk bus bar or the branch conductive bar, etc., protect between the neutral terminal and the trunk bus bar. Boards are erected. As shown in FIG. 5, such a protective plate 21 is usually formed by attaching a mounting plate portion 22 bent at the lower end thereof to a neutral pole base 24 with a tapping screw 23. However, in the case of such a conventional one, it is necessary to perform a punching process with a press and then a bending process in order to manufacture the mounting plate portion 22, and the mounting process is performed by the tapping screw 23. It was troublesome.
【０００３】[0003]
本考案はこのような従来の問題点を解消し、保護板の製造及び取付けを容易に した分電盤を提供するためになされたものである。 The present invention has been made to solve such conventional problems and to provide a distribution board in which the protection plate is easily manufactured and attached.
【０００４】[0004]
上記の課題は、ニュートラル端子を主幹用母線の末端に集合配置した分電盤に おいて、側部に拡大孔部を連設した２個の鉤孔と、その中央に位置しかつ拡大孔 部とは反対側に偏った位置にある挿込孔とを中性極用ベースに透設しておき、下 端両側に前記拡大孔部に挿通される掛鉤部を備えまた下端中央部に挿込片部を備 えた保護板を、掛鉤部を鉤孔に差し込み、また挿込片部を挿込孔に差し込むこと によってニュートラル端子と主幹用母線との間に立設させたことを特徴とする分 電盤により解決することができる。 In the distribution board in which the neutral terminals are collectively arranged at the end of the main bus for the main trunk, the above-mentioned problems are caused by the two hook holes with the enlarged holes connected to the side and the enlarged hole located at the center of the hook holes. An insertion hole located on the opposite side of the base is transparently provided on the neutral pole base, and hooks that are inserted into the enlarged holes are provided on both sides of the lower end. The protective plate with one part is characterized in that the hook part is inserted into the hook hole, and the insertion piece part is inserted into the insertion hole so as to stand upright between the neutral terminal and the main bus. It can be solved by an electric board.
【０００５】[0005]
次に、本考案の実施例を図面に基づいて詳細に説明する。 図１において、１は主幹用ベース２に取り付けた主幹用回路遮断器であり、該 主幹用回路遮断器１には主幹用母線３である２本の電圧母線4a、4aと中性母線4b が接続されている。５は分岐用ベース６に取り付けた分岐用の単極回路遮断器で あり、各単極回路遮断器５は分岐用導電バー７を介して前記電圧母線4aと接続さ れている。８は中性極用ベース９に取り付けたニュートラル端子で、該ニュート ラル端子８は前記中性母線4bと該中性母線4bの下端に接続したニュートラルバー 10を介して接続されている。 Next, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a main circuit breaker attached to a main base 2, and the main circuit breaker 1 includes two voltage bus lines 4a, 4a and a neutral bus line 4b which are main bus lines 3. It is connected. Reference numeral 5 is a branching single-pole circuit breaker attached to a branching base 6, and each single-pole circuit breaker 5 is connected to the voltage bus bar 4a through a branching conductive bar 7. Reference numeral 8 denotes a neutral terminal attached to the neutral pole base 9, and the neutral terminal 8 is connected via the neutral bus bar 4b and a neutral bar 10 connected to the lower end of the neutral bus bar 4b.
【０００６】 11はニュートラル端子８と主幹用母線３との間に立設された絶縁性に優れた合 成樹脂製などの保護板である。保護板11は、図２、図３及び図４に示すように下 端両側に掛鉤部12、12を連設するとともに、下端中央部に挿込片部13を連設した ものである。 また前記中性極用ベース９には、側部に前記掛鉤部12を挿通できる拡大孔部14 を連設した２個の鉤孔15、15と、その中央に位置しかつ拡大孔部14とは反対側に 偏った位置にある挿込孔16とが透設されている。ここで挿込孔16の偏り量は、図 ４に示すように鉤孔15、15の外側を結ぶ直線よりも保護板11の肉厚ｔ程度外側に 寄った程度としておくことが好ましい。Reference numeral 11 is a protective plate made of synthetic resin or the like, which is erected between the neutral terminal 8 and the main bus 3 for the trunk and which has excellent insulation properties. As shown in FIGS. 2, 3 and 4, the protective plate 11 has hooks 12, 12 continuously provided on both sides of the lower end thereof, and an insert piece 13 continuously provided at the center of the lower end. Further, the neutral pole base 9 is provided with two hook holes 15 and 15 which are provided in a side portion with an enlarged hole portion 14 through which the hook portion 12 can be inserted, and an enlarged hole portion 14 located at the center thereof. Has an insertion hole 16 at a position offset to the opposite side. Here, the deviation amount of the insertion hole 16 is preferably set to a degree closer to the outer side by the wall thickness t of the protective plate 11 than the straight line connecting the outer sides of the hook holes 15 and 15, as shown in FIG.
【０００７】 このような保護板11は、その掛鉤部12、12を中性極用ベース９の拡大孔部14に 通し、またその挿込片部13を中性極用ベース９の挿込孔16に挿込み、かつ保護板 11の下端面17を中性極用ベース９の上面に支持させることにより中性極用ベース ９上に立設されている。18は保護板11の中央部下方に透設した中性母線4b挿通用 の窓孔である。In such a protection plate 11, the hooks 12 and 12 are passed through the enlarged hole portion 14 of the neutral pole base 9, and the insertion piece portion 13 is inserted into the insertion hole of the neutral pole base 9. It is erected on the neutral pole base 9 by being inserted into 16 and supporting the lower end surface 17 of the protective plate 11 on the upper surface of the neutral pole base 9. Reference numeral 18 denotes a window hole that is provided below the central portion of the protective plate 11 for inserting the neutral bus bar 4b.
【０００８】 なおこのような保護板11を中性極用ベース９に取り付けるには、まず図３に示 すように保護板11を略水平に近い状態に傾け、下端両側に連設した掛鉤部12、12 を各鉤孔15の拡大孔部14に挿入し、保護板11の下端中央部に連設した挿込片部13 の先端が挿込孔16の孔縁に達したとき保護板11を直立させる。これにより挿込片 部13が拡大孔部14とは反対側に偏った位置にある挿込孔16に嵌合されるとともに 、各掛鉤部12が保護板11の平面状に復帰しようとする力によって拡大孔部14から 挿込孔16の側に移動して鉤孔15に掛止され、保護板11は掛鉤部12、12により抜け 出ることもなく、的確に立設状態を保持して取り付けられるものである。In order to attach such a protection plate 11 to the neutral pole base 9, first, as shown in FIG. 3, the protection plate 11 is tilted to a substantially horizontal state, and a hook portion continuously provided on both sides of the lower end. 12 and 12 are inserted into the enlarged hole portions 14 of the hook holes 15, and when the tip of the insertion piece portion 13 continuously provided at the center of the lower end of the protection plate 11 reaches the edge of the insertion hole 16, the protection plate 11 Upright. As a result, the insertion piece portion 13 is fitted into the insertion hole 16 which is located on the side opposite to the enlarged hole portion 14 and the force with which each hook portion 12 returns to the flat shape of the protection plate 11. It moves from the enlarged hole 14 to the insertion hole 16 side and is hooked on the hook hole 15, and the protective plate 11 does not come off by the hook portions 12 and 12 and is attached while maintaining the upright state accurately. It is what is done.
【０００９】[0009]
このように構成されたものは、負荷側の電線を各単極回路遮断器５の負荷側の 端子とニュートラル端子８の負荷側端子板とに接続して構成した分岐回路の絶縁 抵抗測定等を行うためにニュートラル端子８を操作する場合、主幹用母線３と該 主幹用母線３の末端に集合配置されているニュートラル端子８との間に保護板11 が立設されているので、手指が誤って主幹用母線、分岐用導電バー７に触れるこ とがなく安全に作業できることは従来のこの種の分電盤と同様である。 The one configured in this way is used to measure the insulation resistance of a branch circuit that is configured by connecting the load side wire to the load side terminal of each single pole circuit breaker 5 and the load side terminal plate of the neutral terminal 8. When operating the neutral terminal 8 to perform the operation, the protective plate 11 is erected between the main bus 3 for the main trunk and the neutral terminals 8 collectively arranged at the end of the main bus 3 for the main trunk. It is similar to the conventional distribution board of this type in that it can work safely without touching the main bus for the main trunk and the conductive bar 7 for branching.
【００１０】 しかし本考案においては、保護板11は下端両側に掛鉤部12、12を連設するとと もに下端中央部に挿込片部13を連設した平板状のものでよいので製作が簡単であ り、また前記のように保護板11を中性極用ベース９上に立てた状態として簡単に 取り付けることができるので、保護板11をタッピンねじ等により取付けていた従 来に構造のものに比較して、取付工程を大幅に簡略化することができる。However, in the present invention, the protective plate 11 may be formed in a flat plate shape in which the hook portions 12, 12 are continuously provided on both sides of the lower end and the insertion piece portion 13 is continuously provided at the center of the lower end. It is simple and can be easily attached with the protective plate 11 standing upright on the neutral pole base 9 as described above, so that the protective plate 11 is attached by tapping screws or the like. The mounting process can be greatly simplified as compared with the conventional one.
【００１１】[0011]
本考案は以上に説明したように、保護板を抜き加工のみで製作できるものであ り、また、保護板の下端両側に連設した掛鉤部と下端中央部に連設した挿込片部 とを中性極用ベースに透設した鉤孔と挿込孔に挿込むことにより容易に取り付け ることができるものであるから、従来の問題点を解消した分電盤として、その実 用的価値は極めて大きいものである。 As described above, the present invention can be produced only by punching out the protective plate, and also has a hook part continuously provided on both sides of the lower end of the protective plate and an insertion piece part continuously provided at the center of the lower end. Since it can be easily installed by inserting it into the hook hole and insertion hole that are transparently installed in the neutral pole base, its practical value as a distribution board that solved the conventional problems is It is extremely large.
