Description
【０００１】[0001]
本考案は、発光ダイオードの面アレイ等に裏面から電源を供給する場合のよう に分散分布した多数の電気部品に電源を供給する場合等に用いられる金属性長尺 板状の給電ブスバーを電気機器内の所定位置に支持し固定するための固定具に関 する。 The present invention provides a metal long plate-shaped power supply bus bar used for supplying electric power to a large number of distributed electric components such as when supplying electric power from the back surface to a surface array of light emitting diodes. It relates to a fixture for supporting and fixing at a predetermined position inside.
【０００２】[0002]
例えば、図４の外観正面図及び内部を示す図５に示すような、列車の行き先等 を案内するため等にひろく用いられている発光表示機ＢＤには、面アレイ状に密 に配置された多数の発光ダイオードＬＥＤとこれに対応した駆動用の論理回路が 使用されている。 このように、分散分布した極めて多数の電気部品に電源から大電力を供給する 場合には、従来より図６に示すように配線の簡易化の目的で金属性長尺板状のい わゆる給電ブスバー１０Ｃを裏面に固定具（スペーサ）３０により支持して使用 している。 For example, as shown in the front view of the outer appearance of FIG. 4 and the inner view of FIG. 5, light emitting displays BD widely used for guiding train destinations and the like are densely arranged in a plane array. A large number of light emitting diodes LED and corresponding driving logic circuits are used. As described above, when supplying a large amount of electric power from a power source to an extremely large number of distributed electric components, a metallic long plate-shaped power supply is conventionally used for the purpose of simplifying wiring as shown in FIG. The bus bar 10C is used by being supported on the back surface by a fixture (spacer) 30.
【０００３】 例えば面状の発光表示機であれば表示１文字あたり２４×２４個必要で、従っ て所定量の情報表示のためには極めて多数の発光ダイオードが使用されていて、 発光させるための電源として、或いは個々の発光ダイオードを点灯あるいは滅灯 させ所望の表示内容となるように駆動するための駆動用論理回路のための電源と して大電力を供給しなくてはならない。For example, in the case of a planar light emitting display, 24 × 24 display characters are required for each character. Therefore, an extremely large number of light emitting diodes are used to display a predetermined amount of information, and A large amount of power must be supplied as a power source or as a power source for a driving logic circuit for driving an individual light emitting diode to be turned on or off to obtain a desired display content.
【０００４】 従って給電のための給電ブスバー１０Ｃは、導電性の良いアルミニウムあるい は銅等の金属を用いて長尺板状に形成し、図６に示すように所定各位置に電源部 或いは他の回路部分と電気接続をするための貫通ネジ穴１１を多数設けてある。 また、従来の給電ブスバーには所定位置に取付けのための貫通取付穴１４が設け られている。なお、一般に給電ブスバーの材料には軽量である点また加工性と経 済性に優れている点でアルミニウムが選択されることが多い。Therefore, the power supply bus bar 10C for power supply is formed in a long plate shape by using a metal having good conductivity such as aluminum or copper, and as shown in FIG. A large number of through-screw holes 11 for making electrical connection with the circuit portion of are provided. Further, the conventional power feeding bus bar is provided with a through mounting hole 14 for mounting at a predetermined position. In general, aluminum is often selected as the material of the power supply bus bar because of its light weight and excellent workability and economy.
【０００５】 同じ図６に示す様に従来の給電ブスバー１０Ｃの固定は、絶縁物で成る長さ１ ５ｍｍ〜２０ｍｍ程度の円筒形状で両端に金属ナット３２を埋め込んだ絶縁スペ ーサ３０を用いて、この絶縁スペーサ３０を予め一つずつ発光表示機ＢＤの筐体 内に設けたブスバー取付板２０に裏側からビス３１でスプリングワッシャＳＷや 平座金ＺＧを用いて強固に固定しておき、給電ブスバー１０Ｃを一本ずつ、前記 貫通取付穴１４を絶縁スペーサ３０の残る反対側端部に位置を合わせて、スプリ ングワッシャＳＷや平座金ＺＧを介してビス３１で強固に固定している。As shown in the same FIG. 6, the conventional power supply bus bar 10C is fixed by using an insulating spacer 30 which is made of an insulating material and has a cylindrical shape with a length of about 15 mm to 20 mm and in which metal nuts 32 are embedded at both ends. The insulating spacers 30 are fixed one by one to the bus bar mounting plate 20 provided in the housing of the light emitting display BD in advance from the back side with the screws 31 using the spring washers SW and the flat washers ZG to firmly fix the power supply bus bar. The through-mounting holes 14 are aligned one by one with the opposite ends of the insulating spacers 30 and are firmly fixed with screws 31 via spring washers SW and plain washers ZG.
【０００６】 図７は、上述の従来の方法によりブスバー取付板２０に取付けられた給電ブス バー１０Ｃを用いて所定の配線がされた面状発光表示機ＢＤの表示面の裏側を内 部から見た斜視図で、給電ブスバー１０Ｃの長手方向に適宜間隔で一列ずつ平行 に取付けられている絶縁スペーサ３０により２本〜３本の給電ブスバー１０Ｃが 近接して平行に固定されている。夫々の給電ブスバー１０Ｃには端部の貫通ネジ 穴１１Ａにより電源部（図示せず）からの導線が接続され、又貫通ネジ穴１１Ｂ 、１１Ｃ、…にビス３１により接続された導線Ｌにより各部位の論理回路及び発 光ダイオードへと電力が供給されている。 なお、例に挙げた発光表示機では、誤動作防止のため論理回路部の動作用電源 と発光ダイオードの点灯用電源とを別電源としているため負極を共通として１ブ ロック（一列）の発光ダイオード及び駆動用論理回路夫々につき計３本の給電ブ スバー１０Ｃが用いられている。FIG. 7 is a view showing the inside of the backside of the display surface of the planar light emitting display BD in which predetermined wiring is performed using the power supply busbar 10C attached to the busbar attachment plate 20 by the above-described conventional method. In the perspective view, two to three power feeding busbars 10C are fixed in close proximity to each other by insulating spacers 30 which are mounted in parallel one by one in the longitudinal direction of the power feeding busbar 10C at appropriate intervals. Each of the power supply busbars 10C is connected to a lead wire from a power source (not shown) by a through screw hole 11A at the end, and each portion is connected by a lead L connected to the through screw holes 11B, 11C ,. Power is supplied to the logic circuit and the light emitting diode. Note that in the light-emitting display device given as an example, the power supply for operating the logic circuit section and the power supply for lighting the light-emitting diode are separate power supplies to prevent malfunction, so that the negative electrode is common and one block (one row) of light-emitting diodes and A total of three power supply bus bars 10C are used for each driving logic circuit.
【０００７】[0007]
ところで、上述した絶縁スペーサ３０を用いた従来の給電ブスバーの固定は、 １本の給電ブスバー毎に独立して行い、１本の給電ブスバーに対して夫々１列の 複数の絶縁スペーサ３０が必要で全体では極めて多くのスペーサと対応するねじ 止め作業を必要とし給電ブスバーの取付けに際して多大な労力を必要とした。 また、絶縁スペーサの回転ゆるみを防止するためのスプリングワッシャＳＷや 平座金ＺＧの併用が作業を一層煩雑にしていた。 By the way, the conventional fixing of the power feeding bus bars using the insulating spacers 30 is performed independently for each power feeding bus bar, and a plurality of insulating spacers 30 in one row are required for each power feeding bus bar. As a whole, an extremely large number of spacers and corresponding screwing work were required, and a great deal of labor was required when installing the power supply bus bar. Further, the combined use of the spring washer SW and the flat washer ZG to prevent the loosening of the insulating spacer from rotating further complicates the work.
【０００８】 本考案は、上述の如く従来の給電ブスバーの固定には多くの作業時間を費やし てしまうとの問題点に鑑みて成されたもので、給電ブスバーの固定作業を極めて 簡易に行い作業時間を激減させることのできる新規な給電ブスバー固定具を提案 することを課題として成されたものである。The present invention has been made in view of the problem that a lot of work time is spent for fixing the conventional power supply bus bar as described above, and the work for fixing the power supply bus bar is extremely simple. The challenge was to propose a new power supply busbar fixture that can drastically reduce the time.
【０００９】[0009]
上記課題を解決するために本願第一の考案では、金属性長尺板状の給電ブスバ ーの固定具を、 略直方体形状の電気絶縁物で成り、電気機器への取付平面と反対側の上面には 収容する給電ブスバーの板幅に対応する溝幅の収容溝部が単独に又は互いに平行 に形成されていて、前記収容溝部各々が、前記取付面に平行で所定距離に位置し ていて給電ブスバーの板面の一方が当接する支持平面部と、この支持平面部を挟 む両側方に位置し前記支持平面部から給電ブスバーの板厚と略距離の等しい位置 から内方に突出する係止突部が形成されており、また給電ブスバーを幅方向から 挟持する一対の挟持側壁と、給電ブスバーに設けた被係止部と係接して収容され た給電ブスバーの長手方向への移動を係止する係止部とを具備したものである構 成とする。 In order to solve the above-mentioned problems, in the first invention of the present application, the fixing member for the metallic long plate-shaped power feeding bus bar is made of a substantially rectangular parallelepiped-shaped electrical insulator, and the upper surface on the side opposite to the mounting plane to the electric device is formed. Are formed independently or in parallel with each other with a groove width corresponding to the plate width of the power feeding bus bar to be housed, and each of the housing groove portions is located at a predetermined distance in parallel with the mounting surface. One of the plate surfaces of the supporting flat surface is in contact with the supporting flat surface, and the locking projections are located on both sides of the supporting flat surface and inwardly project from the supporting flat surface at a position substantially equal to the thickness of the feeding bus bar. And a pair of sandwiching side walls for sandwiching the power feeding bus bar from the width direction and a locked portion provided on the power feeding bus bar are engaged with each other to lock the movement of the power feeding bus bar in the longitudinal direction. Structure comprising a locking portion And
【００１０】 また本願第二の考案では、上述給電ブスバー固定具において、前記取付平面に 電気機器のブスバー取付板に設けられた取付穴部に係合する取付突部と、前記ブ スバー取付板を介してタッピングねじが螺入される下穴が形成された構成とする 。Further, in the second invention of the present application, in the above-described power supply bus bar fixture, the mounting protrusion engaging with the mounting hole provided in the bus bar mounting plate of the electric device on the mounting plane, and the bus bar mounting plate are provided. A prepared hole is formed in which the tapping screw is screwed in.
【００１１】[0011]
本願第一の考案では、この給電ブスバー固定具を予め電気機器のブスバー取付 板の所定位置に裏側からのねじ止め等により取付けておけば、１列に取付けられ た各給電ブスバー固定具に単に位置を合わせて対応する給電ブスバーを収容溝部 に押し込むのみで固定が完了する。即ち、押し込むという簡単な工程のみで給電 ブスバーの片面は支持平面部に当接して取付基板と平行な位置となり、同時に内 方に付勢された挟持側面部上部の突部が給電ブスバーの上面と係接して給電ブス バーを前記支持平面部に密着させながら幅方向から挟持し、また係止部が給電ブ スバーの被係止部と係接して給電ブスバーの長手方向への移動を防止する。この 様に給電ブスバーのねじ止めが不要であり作業が極めて簡単となる。 なお、収容溝部を平行に複数設けたものでは一列の固定具にて複数本のブスバ ーの固定が一度にできる。従って、固定具を固定するための作業時間も従来の絶 縁スペーサを用いる場合よりも減少する。 According to the first invention of the present application, if the power feeding bus bar fixing device is previously mounted at a predetermined position of the bus bar mounting plate of the electric device by screwing from the back side or the like, the power feeding bus bar fixing devices are simply positioned on the power feeding bus bar fixing devices mounted in one row. The fixing is completed simply by pushing the corresponding power supply bus bar into the accommodation groove. That is, with only a simple process of pushing, one side of the power feeding busbar comes into contact with the supporting flat surface and becomes parallel to the mounting substrate, and at the same time, the protrusion on the upper side of the sandwiching side portion biased inward is the upper surface of the power feeding busbar. The power feeding bus bar is pinched from the width direction while being brought into close contact with the support plane portion, and the locking portion is brought into contact with the locked portion of the power feeding bus bar to prevent the power feeding bus bar from moving in the longitudinal direction. In this way, it is not necessary to screw the power supply bus bar, and the work is extremely simple. In addition, in the case where a plurality of accommodation groove portions are provided in parallel, a plurality of bus bars can be fixed at one time by a single row of fixing devices. Therefore, the working time for fixing the fixing device is also reduced as compared with the case of using the conventional insulating spacer.
【００１２】 また、本願第二考案の給電ブスバー固定具は、電気機器のブスバー取付板への 取付けに際して、取付突部をブスバー取付板の取付穴部に係合させ取付基板裏面 からタッピングねじを下穴に螺入するのみで給電ブスバー固定具は強固に固定さ れ回転することもない。即ち、タッピングねじのみで簡易に取付基板に対して固 定される。Further, in the power feeding bus bar fixing device of the second invention of the present application, when mounting the electric device on the bus bar mounting plate, the mounting projection is engaged with the mounting hole part of the bus bar mounting plate and the tapping screw is lowered from the rear surface of the mounting substrate. The power supply bus bar fixture is firmly fixed only by screwing it into the hole and does not rotate. That is, it is easily fixed to the mounting substrate with only the tapping screw.

以下、本考案を実施例に基づいて添附図面を用いて詳細に説明する。 図１は、本願第一考案の給電ブスバー固定具の一実施例を示す側面図及び上面 図等である。 図の給電ブスバー固定具１Ａは、略直方体形状の電気絶縁物１ａであり、その 一面は電気機器のブスバー取付板２０と接する取付平面１ｆとなっていて、この 取付平面１ｆと反対側（上面）には、対応する給電ブスバー１０Ａの板幅に対応 してこれより僅かに大きい溝幅の収容溝部２が図の例では３ヵ所互いに平行に直 方体状の前記絶縁物１ａの一対の側面に開口して形成されている。 Hereinafter, the present invention will be described in detail based on embodiments with reference to the accompanying drawings. FIG. 1 is a side view and a top view showing an embodiment of a power supply bus bar fixing device of the first invention of the present application. The power supply busbar fixture 1A shown in the figure is a substantially rectangular parallelepiped electrical insulator 1a, one surface of which is a mounting plane 1f in contact with a busbar mounting plate 20 of an electric device, and the other side (upper surface) of this mounting plane 1f. In the illustrated example, three accommodation grooves 2 having a groove width slightly larger than the corresponding width of the corresponding power supply bus bar 10A are formed on the pair of side surfaces of the rectangular parallelepiped insulator 1a parallel to each other. It is formed by opening.
【００１４】 この収容溝部２の底部分には取付平面１ｆから所定距離離れて平行に支持平面 部１ｂが形成されていて、収容された給電ブスバー１０Ａの一方の板面が当接す る。この支持平面部１ｂを挟んで両側方の壁部は挟持側壁１ｃとなっていて給電 ブスバー１０Ａが収容されると幅方向からその側面を内方に挟持付勢する。また この挟持側壁１ｃ夫々には前記支持平面部１ｂ（の延長面）から給電ブスバーの 板厚と略等しい距離にある位置から内方に突出している係止突部１ｄが形成され ている。係止突部１ｄの上方部は斜面に形成されていて給電ブスバー１０Ａを上 方から容易に挿入することができる。A support plane portion 1b is formed in parallel at a bottom portion of the accommodation groove portion 2 at a predetermined distance from the mounting plane 1f, and one plate surface of the accommodated power feeding bus bar 10A abuts on the support plane portion 1b. The wall portions on both sides of the support plane portion 1b are sandwiching side walls 1c, and when the power feeding bus bar 10A is housed, the side surfaces thereof are sandwiched and urged inward from the width direction. Further, each of the sandwiching side walls 1c is formed with a locking projection 1d which projects inward from a position at a distance approximately equal to the plate thickness of the power feeding bus bar from (the extension surface of) the supporting flat surface 1b. The upper portion of the locking projection 1d is formed in a slope, so that the power feeding bus bar 10A can be easily inserted from above.
【００１５】 また、収容溝部２の所定位置、実施例では前記支持平面部１ｂの中央部に係止 部である円柱状の係止突起１ｅが形成されている。この係止突起１ｅ（係止部） は給電ブスバー１０Ａを収納した場合に、予め対応して給電ブスバー１０Ａ側に 形成してある被係止部である係止貫通穴１２の内部に位置して給電ブスバー１０ Ａの長手方向への移動を係止するために設けられたものである。Further, a cylindrical locking protrusion 1e, which is a locking portion, is formed at a predetermined position of the accommodation groove portion 2, in the embodiment, at the center of the support plane portion 1b. When the power feeding bus bar 10A is stored, the locking protrusion 1e is located inside the locking through hole 12 which is a locked portion formed on the power feeding bus bar 10A side in advance. This is provided to lock the movement of the power feeding bus bar 10A in the longitudinal direction.
【００１６】 １ｇは、隣接する前記収容溝部３同士の間に設けられた溝で、前記挟持側壁１ ｃの肉厚を薄くして弾性を増し給電ブスバー１０Ａを収容溝部２へ挿入するのを 容易とするために設けられている。同様に挟持側壁１ｃの弾性を増すために前記 収容溝部の底部の両端部分には溝１ｇ′が設けられて挟持側壁１ｃの薄肉部を下 方に延長している。Reference numeral 1g denotes a groove provided between the adjacent accommodation groove portions 3 to facilitate insertion of the power feeding bus bar 10A into the accommodation groove portion 2 by reducing the thickness of the sandwiching side wall 1c to increase elasticity. It is provided for the purpose. Similarly, in order to increase the elasticity of the sandwiching side wall 1c, grooves 1g 'are provided at both ends of the bottom portion of the accommodation groove portion to extend the thin portion of the sandwiching side wall 1c downward.
【００１７】 なお、取付面１ｆには雌ねじ孔１ｈが２か所形成されており、対応してブスバ ー取付板２０に設けられた取付貫通孔とこの雌ねじ孔１ｈの位置を合わせブスバ ー取付板２０の裏面よりビス３１をねじ止めすることにより給電ブスバー１０Ａ をブスバー取付板２０に固定する。Two female screw holes 1h are formed on the mounting surface 1f. Correspondingly, the positions of the mounting through holes provided in the bus bar mounting plate 20 and the female screw holes 1h are matched to each other. The power supply bus bar 10A is fixed to the bus bar mounting plate 20 by screwing screws 31 from the back surface of the power supply bus 20.
【００１８】 以上のような構成により、予めブスバー取付板２０の所定各位置に夫々本願考 案の給電ブスバー固定具１Ａをビス３１を用いて固定しておけば、給電ブスバー １０Ａを取付けのため収容溝部３に押し込むのみで固定作業は完了し、給電ブス バー１０Ａの片面は支持平面部１ｂに当接してブスバー取付板２０と平行な姿勢 となり、同時に挟持側壁１ｃが給電ブスバー１Ａの側面と又上部の突部１ｄが給 電ブスバーの上面と係接して給電ブスバー１０Ａを前記支持平面部１ｂに密着さ せながら幅方向から挟持する。また係止部（係止突起）１ｅが給電ブスバーの被 係止部（貫通孔）１２と係接して給電ブスバーの長手方向への移動を防止する。With the above configuration, if the power feeding bus bar fixing tool 1A of the present invention is fixed to each predetermined position of the bus bar mounting plate 20 in advance by using the screw 31, the power feeding bus bar 10A is accommodated for mounting. The fixing work is completed simply by pushing it into the groove portion 3, and one side of the power feeding bus bar 10A comes into contact with the supporting flat surface portion 1b to be in a posture parallel to the bus bar mounting plate 20. The projecting portion 1d is in contact with the upper surface of the power feeding bus bar to hold the power feeding bus bar 10A in close contact with the supporting flat surface portion 1b and sandwich it from the width direction. The locking portion (locking protrusion) 1e engages with the locked portion (through hole) 12 of the power feeding bus bar to prevent the power feeding bus bar from moving in the longitudinal direction.
【００１９】 この様に本願考案の給電ブスバー固定具１Ａを用いると給電ブスバーの固定作 業には、ねじ止めが不要となり取付作業が極めて簡単となる。 その他、従来見られたねじの緩みにより給電ブスバーが移動してブスバー間の 短絡が発生するという事故が防止できるという副次的効果もある。 なお、上記給電ブスバーの材料に適する絶縁物としては、ポリカーボネートや ポリアセタール等の合成樹脂があり、これらを用いて一体成形品として固定ブス バー１０Ａを量産することができる。As described above, when the power feeding bus bar fixing tool 1A of the present invention is used, the power feeding bus bar fixing operation does not require screwing and the mounting work is extremely simple. In addition, there is a secondary effect that it is possible to prevent the accident that the power supply busbar moves due to the looseness of the screw that has been seen in the past and a short circuit occurs between the busbars. As an insulator suitable for the material of the power feeding bus bar, there are synthetic resins such as polycarbonate and polyacetal, and the fixed bus bar 10A can be mass-produced as an integrally molded product by using these.
【００２０】 上記の実施例では給電ブスバーを３連として固定するために収納溝部２を平行 に３つ設けたものを示したが、２連あるいは４連としても良いことは勿論である 。なお、複数の給電ブスバーを一度に固定するようにすると、平行している各給 電ブスバーの位置決め精度が向上するため接近して配置することができこれによ り省スペース化が計れるという副次的効果も生ずる。 勿論、収納溝部３を１つのみ設け単一の給電ブスバーを固定するようにしても 良くこの場合にも相応の省力化が計れる。In the above-mentioned embodiment, three storage groove portions 2 are provided in parallel in order to fix the power supply busbars in three rows, but it is needless to say that two storage rows or four storage slots may be provided. If multiple power supply busbars are fixed at once, the positioning accuracy of each power supply busbar in parallel will be improved and they can be placed close to each other, which can save space. Effect also occurs. Of course, it is also possible to provide only one storage groove portion 3 and fix a single power supply bus bar, and in this case as well, corresponding labor saving can be achieved.
【００２１】 図２は、上述したような給電ブスバー固定具１Ａを用いて、既述した発光表示 機ＢＤの裏側に給電ブスバー１０Ａを固定した一例を示す斜視図である。 図では、給電ブスバー１０Ａを３本一組にして一列に配置された給電ブスバー 固定具１Ａ1 、１Ａ2 、…、…により整然と固定している。同じく２本一組とし た給電ブスバー１０Ａも一列に配置された給電ブスバー固定具１Ａａ、１Ａｂ、 …、…により整然と固定されている。FIG. 2 is a perspective view showing an example in which the power supply busbar 10A is fixed to the back side of the above-described light emitting display BD using the power supply busbar fixture 1A as described above. In the figure, feeder bus bar 10A 3 present one set in to the feeding are arranged in a row bus bars fixture 1A 1, 1A 2, ..., it is secured neatly by .... Similarly, the pair of power feeding bus bars 10A are also fixed orderly by the power feeding bus bar fixing tools 1Aa, 1Ab ,.
【００２２】 次に、図３は本願第二考案の給電ブスバー固定具の一実施例を示す側面図及び 上面図等である。本願第二考案の固定具は、第一考案のものに更に機器のブスバ ー取付板への取付をも配慮して構成されたものある。 図３の給電ブスバー固定具１Ｂの各部は、前実施例と略同様に構成されていて 、勿論第一考案と同様に給電ブスバー１０の取付固定が容易であるが、加えて取 付平面１ｅにはブスバー取付板２０への取付作業をより簡易にするために、位置 決め突部１ｉとタッピングねじを螺入するための下穴１ｊが形成してある。これ により、ブスバー取付板２０の所定位置に前記位置決め突部１ｉに対応した略同 一径の貫通穴２１と、前記下穴１ｊに対応する貫通穴２２を設けて置き、タッピ ングねじ３３を用いることで取付作業が簡単に行える。Next, FIG. 3 is a side view and a top view showing one embodiment of the power feeding bus bar fixing device of the second invention of the present application. The fixture of the second invention of the present application is constructed in consideration of the attachment to the bus bar mounting plate of the device in addition to the fixture of the first invention. Each part of the power feeding bus bar fixing tool 1B of FIG. 3 is constructed in substantially the same manner as in the previous embodiment, and of course the power feeding bus bar 10 can be easily mounted and fixed as in the first invention, but in addition to the mounting plane 1e. In order to make the mounting work on the bus bar mounting plate 20 easier, the positioning projection 1i and the pilot hole 1j into which the tapping screw is screwed are formed. As a result, a through hole 21 having substantially the same diameter corresponding to the positioning projection 1i and a through hole 22 corresponding to the pilot hole 1j are provided at predetermined positions of the bus bar mounting plate 20, and the tapping screw 33 is used. By doing so, installation work can be done easily.

以上詳述したとおり本願第一考案の給電ブスバー固定具は、 略直方体形状で取付平面と反対側の上面には給電ブスバーに対応する溝幅の収容 溝部が単独に又は互いに平行に形成されており、前記収容溝部各々が、支持平面 部と、両側方の所定位置から内方に突出する突部を形成した一対の挟持側壁と、 給電ブスバーの長手方向への移動を係止する係止部とを具備しているから、 電気機器に取付後、対応する給電ブスバーを単に位置を合わせて収容溝部に押 し込むのみで固定が完了し作業が極めて簡単であるが、給電ブスバーが脱落した り移動したりすることが無い。 なお、収容溝部を平行に複数設けたものでは一列の固定具にて複数本のブスバ ーの固定が一度にできるより固定作業時間が減少する。 また、平行している各給電ブスバーの位置決め精度が向上するため接近して配 置し省スペース化を計ることができる。 As described in detail above, the power feeding bus bar fixing device of the first invention of the present application has a substantially rectangular parallelepiped shape, and the receiving groove portion having a groove width corresponding to the power feeding bus bar is formed alone or in parallel with each other on the upper surface opposite to the mounting plane. Each of the accommodation groove portions has a supporting flat surface portion, a pair of sandwiching side walls formed with protrusions protruding inward from predetermined positions on both sides, and a locking portion for locking movement of the power feeding bus bar in the longitudinal direction. Since it is equipped with electrical equipment, fixing is completed by simply aligning the corresponding power supply bus bar and pushing it into the accommodation groove after mounting it on the electrical equipment, and the work is extremely easy, but the power supply bus bar drops or moves. There is nothing to do. If a plurality of housing grooves are provided in parallel, the fixing work time will be shorter than the case where a plurality of bus bars can be fixed at once with a single row of fixing tools. In addition, since the positioning accuracy of the parallel power supply busbars is improved, they can be placed close to each other to save space.
【００２６】 また、本願第二考案の給電ブスバー固定具は、 上記考案の構成に加えて更に電気機器のブスバー取付板の取付穴部と係合する 取付突部とブスバー取付板を介してタッピングねじが螺入される下穴を取付平面 に具備しているから、 上述効果に加えて、極めて簡単に取付基板に固定することができるとの効果が ある。In addition to the structure of the above invention, the power supply bus bar fixing device of the second invention of the present application further taps a tapping screw via a mounting projection and a bus bar mounting plate that engage with a mounting hole of a bus bar mounting plate of an electric device. Since the mounting plane is provided with the prepared hole into which is mounted, in addition to the above-mentioned effect, there is an effect that it can be extremely easily fixed to the mounting substrate.
