Description
【０００１】[0001]
この考案は、配電盤等に適用される帯状の分電用母線の絶縁支持台に関する。 The present invention relates to an insulating support base for a strip-shaped distribution busbar applied to a switchboard or the like.
【０００２】[0002]
この種の支持台に関する従来技術に実公平２−４２０１５号公報があり、そこ では３個の分電用母線（以下単に母線という）をその面壁どうしが対向する状態 で平行に配置し、これら母線を断面コ字形のクリート部材で上下から直交状に挟 み固定する。クリート部材には、一定間隔おきに溝を形成してあり、この溝に母 線を嵌め込んで母線間隔を保持している。 別の従来例に特開昭５７−９２７１２号公報があり、そこでは対向する壁面間 にボルトと絶縁パイプを固定し、絶縁パイプに３個の母線を外嵌装着し、各母線 間および母線と壁面との間に中空筒状のスペーサを配置して、各母線をその面壁 どうしが対向する状態で平行に支持している。 Japanese Patent Publication No. 2-42015 discloses a prior art relating to this type of support, in which three distribution busbars (hereinafter simply referred to as busbars) are arranged in parallel with their surface walls facing each other. Is clamped and fixed vertically from above and below by cleat members with a U-shaped cross section. Grooves are formed at regular intervals on the cleat member, and a busbar is fitted into the groove to maintain the busbar spacing. Another conventional example is Japanese Patent Laid-Open No. 57-92712, in which a bolt and an insulating pipe are fixed between opposing wall surfaces, and three busbars are externally fitted and attached to the insulating pipes, and each busbar and each busbar are connected to each other. A hollow cylindrical spacer is placed between the wall and each busbar, and the busbars are supported in parallel with their surface walls facing each other.
【０００３】[0003]
従来の絶縁支持台では、母線を面壁どうしが互いに正対する状態で平行に支持 する。そのため、分岐端子を母線に接続する際に、隣接する母線が邪魔になって 接続作業を迅速に行えず、しかも分岐端子の取付位置が母線の幅方向一側に限ら れていた。母線の厚みが変わるのに応じて、溝の幅やスペーサの幅を変更しなけ ればならず、現場加工に手間を要し、あるいは幅寸法が僅かずつ異なるスペーサ を予め多数種用意する必要があり、いずれにしても費用が高く付いていた。 In a conventional insulating support, the busbars are supported in parallel with the surface walls facing each other. Therefore, when the branch terminal is connected to the bus bar, the adjacent bus bar interferes with the connection work and the connecting work cannot be performed quickly, and the mounting position of the branch terminal is limited to one side in the width direction of the bus bar. As the thickness of the busbar changes, the width of the groove and the width of the spacer must be changed, which requires time and labor for on-site processing, or it is necessary to prepare many types of spacers with slightly different width dimensions in advance. Yes, the cost was high anyway.
【０００４】 例えば、帯状の母線を側縁壁どうしが対向する状態で配置すると、全ての母線 の面壁が上下あるいは前後に露出するので、接続作業を容易化でき、さらに母線 の厚みの変化とは無関係にその取り付けを行える。しかし、その場合は上記従来 の母線配置形態に比べて、母線の配置に要するスペースが数倍にも増え、スペー ス上の制約で実用的でない。For example, when the strip-shaped busbars are arranged with the side edge walls facing each other, the surface walls of all the busbars are exposed vertically or in the front and back, so that the connection work can be facilitated and the change in the thickness of the busbars It can be attached independently. However, in that case, the space required for arranging the busbars is increased several times as compared with the conventional busbar layout, and it is not practical due to space restrictions.
【０００５】 そこで本考案の目的は、分岐端子の接続作業を容易に行え、母線の厚み変化に 対応でき、さらに母線の配置に要するスペースも少なくて済む絶縁支持台を得る にある。Therefore, an object of the present invention is to provide an insulating support base that can easily perform branch terminal connection work, can cope with changes in the thickness of the bus bar, and that requires less space for disposing the bus bar.
【０００６】[0006]
本考案は、金属製の帯状導体からなる分電用母線１の複数個を平行姿勢で支持 する絶縁支持台２において、直線状の基部６と、基部６の上面から一体に突出さ れて分電用母線１の一方の面壁４を受け止める複数個の取付部７とを備えている こと、前記面壁４と接当する取付部７の母線受面７ａが、基部６に対して所定角 度αを以て傾斜する状態で平行に配置されていること、取付部７には母線受面７ ａに対して開口するねじ穴１１が設けられていること、分電用母線１が該ねじ穴 １１を利用して取付部７の母線受面７ａにボルト止めされるようにしたことを要 件とする。 母線受面７ａの傾斜角度αは、３０〜６０度の範囲で設定することが好ましく 、より好ましくは、４０〜５０度の範囲で設定する。 According to the present invention, in an insulating support base 2 that supports a plurality of distribution busbars 1 made of metal strip conductors in a parallel posture, a linear base portion 6 and an upper portion of the base portion 6 are integrally projected and divided. A plurality of mounting portions 7 for receiving one surface wall 4 of the electric bus 1 are provided, and the bus bar receiving surface 7a of the mounting portion 7 that abuts the surface wall 4 has a predetermined angle α with respect to the base 6. Are arranged in parallel in a slanted state, the mounting portion 7 is provided with a screw hole 11 that opens to the busbar receiving surface 7a, and the distribution busbar 1 uses the screw hole 11 Then, it is necessary to be bolted to the bus bar receiving surface 7a of the mounting portion 7. The inclination angle α of the busbar receiving surface 7a is preferably set in the range of 30 to 60 degrees, and more preferably set in the range of 40 to 50 degrees.
【０００７】[0007]
絶縁支持台２に母線１を取り付けるに際しては、該支持台２の母線受面７ａに 各母線１の面壁４を当て付け、ボルト１４をねじ穴１１にねじ込んで固定する。 このとき、母線受面７ａは傾斜しているので、ボルト１４は隣の取付部７に邪魔 されることなくねじ込み操作できる。 前記支持台２に母線１を取り付けた状態において、各母線１は隣接する側縁壁 ５どうしが重ならない状態で傾斜している。そのため、各母線１の面壁４が隣接 する母線１で遮られることなく、全面的に露出する。 When the bus bar 1 is attached to the insulating support base 2, the surface wall 4 of each bus bar 1 is applied to the bus bar receiving surface 7a of the support base 2, and the bolt 14 is screwed into the screw hole 11 to be fixed. At this time, since the bus bar receiving surface 7a is inclined, the bolt 14 can be screwed in without being disturbed by the adjacent mounting portion 7. When the busbars 1 are attached to the support base 2, the busbars 1 are inclined such that the adjacent side edge walls 5 do not overlap each other. Therefore, the surface wall 4 of each busbar 1 is exposed without being blocked by the adjacent busbars 1.
【０００８】[0008]
従って本考案の絶縁支持台２に対して各母線１を容易にボルト止めできる。し かも、各母線１は一定方向へ傾斜する状態で平行に支持して、それぞれの面壁４ が露出するようにしたので、分岐端子１５を母線１に接続するについて、ドライ バーやレンチなどの締付工具が隣接する母線１で邪魔されることがなく、各母線 １への分岐端子１５の接続作業を容易にしかも迅速に行える。 さらに、取付部７のねじ穴１１にねじ込まれるボルト１４で母線１を直接締結 するので、母線１はこれの厚みが異なっても一切の支障なく取り付けることがで き、支持台２を厚みの異なる複数種の母線１の支持に共通して適用できる。 母線１を側縁壁５どうしが対向する状態で配置する場合に比べて、母線１の配 置に要するスペースを減らすことができ、配電盤などに母線１を配設する際のス ペース上の制約を大幅に軽減できる。 Therefore, each bus bar 1 can be easily bolted to the insulating support base 2 of the present invention. However, since each busbar 1 is supported in parallel in a state of being inclined in a certain direction so that each face wall 4 is exposed, when connecting the branch terminal 15 to the busbar 1, tighten a screwdriver or a wrench. The attached tool is not disturbed by the adjacent busbars 1, and the work of connecting the branch terminals 15 to each busbar 1 can be performed easily and quickly. Further, since the busbar 1 is directly fastened by the bolt 14 screwed into the screw hole 11 of the mounting portion 7, the busbar 1 can be mounted without any trouble even if the thickness thereof is different, and the support base 2 having a different thickness is attached. It can be commonly applied to support a plurality of types of bus bars 1. The space required for arranging the busbars 1 can be reduced as compared to the case where the busbars 1 are arranged so that the side edge walls 5 face each other, and there is a space limitation when arranging the busbars 1 on a switchboard or the like. Can be significantly reduced.

図３において、符号１は母線、２は本案の絶縁支持台である。 母線１は銅、アルミニウム等の金属導体の帯状体を所定寸法に切断したもので あり、支持台２の配置間隔に対応して板面の両端寄りおよび中間にボルト孔３を 貫通状に設けてある。母線１において符号４は面壁、５は側縁壁である。 In FIG. 3, reference numeral 1 is a bus bar, and 2 is an insulating support base of the present invention. The busbar 1 is made by cutting a strip of a metal conductor such as copper or aluminum into a predetermined size, and bolt holes 3 are provided in a penetrating manner at both ends and in the middle of the plate surface corresponding to the arrangement interval of the support base 2. is there. In the bus bar 1, reference numeral 4 is a face wall, and 5 is a side edge wall.
【００１０】 図１および図２において絶縁支持台２は、ポリプロピレン製の射出成形品から なり、直線状の基部６と、該基部６の上面に突出した鋸刃状の取付部７とを一体 に形成してあり、基部６の両端に六角穴付ボルト８が通る締め付座９を形成して ある。 取付部７は一定間隔おきに３個設けてあり、基部６に対してそれぞれ所定角度 αずつ傾く母線受面７ａと、逆向きに傾く斜面７ｂとを有する不等辺三角形状の 断面を呈している。 母線１をボルト止めするために、母線受面７ａにナット１０をインサート固定 している。１１はそのためのねじ穴であり、該ねじ穴１１は母線受面７ａに対し て開口している。In FIG. 1 and FIG. 2, the insulating support base 2 is made of polypropylene injection-molded product, and has a linear base portion 6 and a saw blade-shaped mounting portion 7 protruding from the upper surface of the base portion 6 which are integrally formed. The base 6 is formed with fastening seats 9 through which the hexagon socket head cap screws 8 pass. The three mounting portions 7 are provided at regular intervals, and have an isosceles triangular cross section having a generatrix receiving surface 7a inclined by a predetermined angle α with respect to the base portion 6 and an inclined surface 7b inclined in the opposite direction. .. In order to bolt the busbar 1, the nut 10 is insert-fixed to the busbar receiving surface 7a. Reference numeral 11 denotes a screw hole therefor, and the screw hole 11 is opened to the bus-bar receiving surface 7a.
【００１１】 図１において、絶縁支持台２は制御盤内の固定壁１３に六角穴付ボルト８で取 り付ける。次に、母線１の面壁４を母線受面７ａに接当させ、各ボルト孔３を介 してボルト１４を斜め上方からねじ穴１１にねじ込むことにより、母線１を一定 方向に傾斜した状態で互いに平行に支持する。このとき、母線受面７ａが傾斜し ているので、ボルト１４は他の取付部７に邪魔されることなく該当のねじ穴１１ にねじ込み操作できる。 母線１から電流を分岐するために、図２に示すごとく各母線１には分岐端子１ ５が取り付けられる。詳しくは、母線１に予めねじ下孔（タップ孔）を形成し、 分岐端子１５をタッピンビス１６で締結する。このとき、各母線１の面壁４は隣 接する母線１に遮られることなく完全に露出している。そのため、ドライバーＴ によるねじ込み作業を隣りの母線１に邪魔されることなく容易に行うことができ る。In FIG. 1, the insulating support base 2 is attached to a fixed wall 13 in the control panel with hexagon socket head cap screws 8. Next, the surface wall 4 of the busbar 1 is brought into contact with the busbar receiving surface 7a, and the bolt 14 is screwed into the screw hole 11 obliquely from above through each bolt hole 3 to keep the busbar 1 inclined in a certain direction. Support parallel to each other. At this time, since the bus bar receiving surface 7a is inclined, the bolt 14 can be screwed into the corresponding screw hole 11 without being disturbed by the other mounting portion 7. In order to branch the current from the bus bar 1, a branch terminal 15 is attached to each bus bar 1 as shown in FIG. Specifically, a screw hole (tap hole) is formed in the bus bar 1 in advance, and the branch terminal 15 is fastened with a tapping screw 16. At this time, the surface wall 4 of each busbar 1 is completely exposed without being blocked by the adjacent busbar 1. Therefore, the screwing operation by the driver T 1 can be easily performed without being disturbed by the adjacent bus bar 1.
【００１２】 母線１の厚み、幅、全長は、それぞれ５mm、３０mm、１０００mmとし、これを ３個の支持台２で支持した。支持台２における母線受面７ａの傾斜角αは４０度 とし、その傾斜方向の長さを母線１の幅寸法と一致させた。隣接する母線受面７ ａの平行間隔Ｐは２５mm、幅寸法は２５mmとした。The busbar 1 has a thickness, a width, and a total length of 5 mm, 30 mm, and 1000 mm, respectively, and is supported by three support bases 2. The inclination angle α of the bus bar receiving surface 7a of the support base 2 was 40 degrees, and the length in the inclination direction was made to match the width dimension of the bus bar 1. The parallel spacing P between the adjacent bus-bar receiving surfaces 7a was 25 mm, and the width dimension was 25 mm.
【００１３】 以上のように構成した絶縁支持台２によれば、取付部７への母線１のボルト止 め作業、および分岐端子１５の母線１への接続作業が隣接する母線１に邪魔され ることなく行えた。母線１の厚みが変わっても、それとは無関係に母線１を支持 台２に装着できた。とくに、支持台２の隣接間隔を余裕を見越して大きめに設定 しておけば、母線１の厚みおよび幅寸法が増加した場合でも、母線間の最小間隔 を適正に維持できる。高い寸法精度が得られる射出成形法によって支持台２を形 成し、その母線受面７ａによって面壁４を面接触状態で支持するので、各母線１ の平行度も高精度に確保できた。According to the insulating support base 2 configured as described above, the bolting work of the busbar 1 to the mounting portion 7 and the connecting work of the branch terminal 15 to the busbar 1 are hindered by the adjacent busbars 1. I was able to do it without any trouble. Even if the thickness of the busbar 1 was changed, the busbar 1 could be attached to the support base 2 regardless of that. In particular, if the spacing between the support bases 2 is set to be large in consideration of a margin, the minimum distance between the busbars can be properly maintained even if the thickness and width of the busbar 1 increase. Since the support base 2 is formed by the injection molding method which can obtain high dimensional accuracy and the surface wall 4 is supported by the bus bar receiving surface 7a in a surface contact state, the parallelism of each bus bar 1 can be secured with high accuracy.
【００１４】 上記実施例では、締め付座９を支持台２の両端に設けたが、締め付座９は支持 台２の周囲であればどこに設けてあってもよい。ねじ穴１１はナット１０をイン サートするに代えて取付部７に直接形成してあってもよい。 支持台２が押出し材からなるものとしてもよく、その場合は所定の長さ寸法に 切断した後、ねじ穴１１と締め付座９を追加工して形成でき、その材質はプラス チック材に限られない。In the above embodiment, the fastening seats 9 are provided at both ends of the support base 2, but the fastening seats 9 may be provided anywhere around the support base 2. The screw hole 11 may be directly formed in the mounting portion 7 instead of inserting the nut 10. The support base 2 may be made of an extruded material. In that case, after cutting it to a predetermined length dimension, the screw hole 11 and the tightening seat 9 can be additionally formed to form the material. I can't.
