Description

【0001】
【発明の属する技術分野】
本発明は主としてユニットの主回路機器の接続構造を改良したコントロールセンタに関する。
【0002】
【従来の技術】
従来より、コントロールセンタは、図6に示すように、箱体1の内部に、遮断器2や、電磁接触器3、過負荷継電器4、及び断路器5のユニット側5aといった主回路機器を有するユニット6を収納して構成されており、それらの主回路機器は、その各接続端子7,8,9,10に電線11,12の端部がそれぞれねじ締めされることによって接続されている。
【0003】
又、断路器5のユニット側5aには、負荷側5bが解離可能に接続結合されており、これの負荷側接続端子13に、モータや、抵抗、照明器具といった負荷を接続するための電線14が、端部を曲げて同じくねじ締めされることによって接続されている。
【0004】
一方、図7は、この従来のコントロールセンタの構成を、箱体21の正面側(図中下側)と背面側(図中上側)との両方に、ユニット6が収納された両面形のもので示しており、各ユニット6は、背面部に設けられた接続端子15を、箱体21の内部中央部分に個別に設けられた母線16に挟み付けることによって接続されている。
【0005】
更に、図7はユニット6の作動点検を行うときの様子をも示しており、箱体1の扉17(図示例は正面側)を開けて、断路器5がユニット側5aと負荷側5bとで解離されるまでユニット6(これも図示例は正面側)を引き出し、この状態で、ユニット6の作動点検を行うようになっている。
【0006】
【発明が解決しようとする課題】
上記従来のものの場合、ユニット6の主回路機器(2〜5)の接続を、主回路機器の各接続端子7,8,9,10に電線11,12の端部をそれぞれねじ締めすることにより行っているため、作業が面倒であり、多くの時間を要していた。
【0007】
、箱体21の正面側と背面側との両方にユニット6が収納された両面形のものにおいては、両ユニット6について、母線16が個別に設けられており、その分、部品点数を多く要すると共に、母線16の個別の組み付けのために手間を多く要していた。
【0008】
本発明は上述の事情に鑑みてなされたものであり、従ってその目的は、ユニットの主回路機器相互の接続が容易且つ速やかにできると共に、両面形のものの母線数の削減ができるコントロールセンタを提供するにある。
【0009】
【課題を解決するための手段】
上記目的を達成するために、本発明のコントロールセンタは、第1に、箱体内に、複数の主回路機器を有するユニットを収納したものにおいて、前記複数の主回路機器にこれらの接続のためにそれぞれ設けられた差込受端子と、この差込受端子にそれぞれ差し込まれて前記複数の主回路機器を接続する接続導体とを具備すると共に、前記ユニットを前記箱体内の正面側と背面側とに有し、その間の中間部に複数の母線を共通に並べ有して、この母線に接続する接続端子を、前記ユニットの各背面部に前記母線の並び方向にスライド可能に、且つ、そのスライド方向の先側と元側とで反転可能に設けたことを特徴とする。
このものによれば、主回路機器の各差込受端子に接続導体を差し込むだけで、主回路機器相互の接続がなされる。又、両面形のものの各ユニットの接続端子を、共通の母線の相の並びと位置とに合うように調整し、この状態で、その各接続端子を共通の母線に接続することができる。
【0013】
【発明の実施の形態】
以下、本発明の基本構造につき、図1ないし図3を参照して説明する。
まず図3には、コントロールセンタ全体の外殻である箱体31を示しており、上下複数段(図示は3段)のユニット室32と、これらに共通の垂直配線処理室33とを左右の並設状態で有している。各ユニット室32の内部には、ユニット34を収納しており(中段のユニット室32についてのみ図示)、ユニット34は、遮断器35、電磁接触器36、過負荷継電器37、及び断路器38といった主回路機器を有し、これらを図示しないユニットフレームに、この場合、すべて横並びの状態で取付けたものである。
【0014】
なお、断路器38は、ユニット側38aと、これに解離可能に接続結合した負荷側38bとから成るもので、ユニット34はそのうちのユニット側38aのみを有しており、負荷側38bは垂直配線処理室33内に位置させて固定している。このほか、ユニット34は、各種表示部や操作部を有する監視・制御機器39をも一体的に有している。
【0015】
しかして、ユニット34の主回路機器(35〜38)には、主回路機器相互接続のための接続端子として、図1に示す差込受端子40を設けている。この差込受端子40は、例えば、一枚の金属板を折曲して、ほゞム字状に三角部40aを形成し、この三角部40aの合わせ頂部から先方へ同様に延びる二つの接触部40bを形成して、更に、その接触部40bの先端部から互いに離反する斜め方向に延びる二つの拡開片部40cを形成したものであり、遮断器35の電磁接触器36側端部、電磁接触器36の遮断器35側端部、過負荷継電器37の断路器38側端部、及び断路器38のユニット側38aの過負荷継電器37側端部に、それぞれ拡開片部40cを前方に向けて、3相分ずつ設けている。
なお、電磁接触器36と過負荷継電器37は別の手段にてあらかじめ一体的に接続結合している。
【0016】
これに対して、図3中、41は第1の接続導体、42は第2の接続導体を示しており、このうち、第1の接続導体41は、詳細には図2に示すように、短冊状を成すもので、両端部を残して絶縁被覆43を例えばコーティングにより施している。
【0017】
この第1の接続導体41を3本使用し、その裸状の各両端部を上記遮断器35及び電磁接触器36の各差込受端子40に差し込んでいる。このとき、第1の接続導体41は、各差込受端子40の拡開片部40c側から差し込み、接触部40bを押し分けて、この接触部40b間に圧入することにより、接触部40bの弾性復元力により、接触部40bと接触しており、かくして、遮断器35と電磁接触器36とを接続している。
【0018】
一方、第2の接続導体42は、図1に示すように、3本を絶縁体44で一まとめに絶縁被覆して成るもので、その絶縁体44は、例えば、第2の接続導体42をインサートして直方体のブロック状にモールドしたものであり、その左右の両側面からは第2の接続導体42の両端部を突出させている。又、絶縁体44の前面部には取手45を、成形により、あるいは別のインサート部品により一体に設けている。
【0019】
この構成で、第2の接続導体42は、取手45を持って、裸状の各両端部を前記過負荷継電器37及び断路器38の各差込受端子40に差し込んでいる。このときも、第2の接続導体42は、各差込受端子40の拡開片部40c側から差し込み、接触部40bを押し分けて、この接触部40b間に圧入することにより、接触部40bの弾性復元力により、接触部40bと接触しており、かくして、過負荷継電器37と断路器38とを接続している。
【0020】
そして、断路器38の前記負荷側38bには、図3に示すように、負荷接続用の接続端子46を設けている。この接続端子46は、その長さを最上部のものから最下部のものへ順に短く定めており、その各先端部に、モータや、抵抗、照明器具といった負荷を接続するための電線47を、箱体31の前記垂直配線処理室33を下方より通して、ほゞ垂直状のまま接続している。
なお、これから明らかなように、接続端子46は、その最上部のものが電線47の導入先側であり、最下部のものが電線47の導入元側である。又、ユニット34の主回路機器のうち、断路器38過負荷継電器37は隣り合う主回路機器である。
【0021】
さて、上述のごとく構成したものの場合、ユニット34の主回路機器相互の接続は、主回路機器の各差込受端子40に接続導体41,42を差し込むだけでなされるものであり、従来の、電線11,12の端部を主回路機器の各接続端子7,8,9,10に逐一ねじ締めしていたもののような手間を要しないので、接続の作業を容易化でき、所要時間も短縮できる。
【0022】
又、第2の接続導体42を、取手45を持って差込受端子40から抜き外せば、ユニット34が負荷側から接続を断たれ、作動点検できる状態になる。従って、このユニット34の作動点検をするときにも、従来の、ユニット6を断路器5がユニット側5aと負荷側5bとで解離されるまで引き出すような手間を要することなくそれができるもので、必要な力も少なくて済み、更に、従来のユニット6を引き出し位置に保持するのに要した複雑な構造も必要とはしない。
【0023】
加えて、負荷を接続するための電線47の接続については、その接続相手である断路器38の負荷接続用の接続端子46の長さを、最上部のものから最下部のものへ順に短く定めたことによって、電線47の接続位置が横方向に異なるようになり、電線47はほゞ直線状のままでそれらに接続できる。従って、この電線47の接続も、従来の、電線14の端部を曲げたような手間を要することなくできるもので、更に、その曲げた電線14の端部の弾性復元力で心配されていた破損のおそれを、接続端子46についてはなくすことができる。
【0024】
以上に対して、図4及び図5は本発明の実施例を示すもので、基本構造と同一の部分には同一の符号を付して説明を省略し、異なる部分についてのみ述べる。
このものの場合、箱体51は、前述の箱体31を2つ、いわゆる背中合わせ状態で設けたものに等しく、その正面側(図中下側)の左寄りのユニット室32と、背面側(図中上側)の右寄りのユニット室32との両方に、それぞれユニット34を収納することにより、両面形のコントロールセンタとしている。
【0025】
又、この場合、両ユニット34間の中間部である箱体51の中央部には、両ユニット34に共通の母線(垂直母線)52を三相分左右方向に並べて設けている。
これに対して、各ユニット34の図5に示すユニットフレーム53の背面部には、左右方向に延びる溝54をスライドガイド部として設けており、この溝54に、母線52に接続するための接続端子55を三相分取付けたスライドベース56を、スライド可能で且つ着脱可能に組み付けている。
【0026】
ここで、母線52は左から順にR相,S相,T相である。従って、これに合わせ、両ユニット34の接続端子55も、同じく左から順にR,S,T相の並びとする必要があるが、背面側(図中上側)のユニット34の接続端子55は、背面側より見た場合、左からは反対のT,S,R相の並びとする必要がある。
【0027】
そこで、背面側のユニット34の接続端子55については、これらをスライドベース56ごとその左右を逆にし、すなわち、左右を反転させて溝54に組み付ける。そして、その後、両ユニット34の各接続端子55をそれぞれスライドベース56ごと溝54に沿って母線52の位置する方向にスライドさせる。従って、この場合、背面側のユニット34の接続端子55は、そのスライド方向の先側と元側とで反転させているのである。
【0028】
かくして、両ユニット34の接続端子55を、母線52の相の並びと位置とに合うように調整し、この状態で、両ユニット34を押し込み、各接続端子55を母線52に挟み付けて接続する。なお、ユニット34の内部の主回路機器、特には遮断器35に対する接続端子55の接続は、例えばスライドベース56から溝54を通した電線(図示せず)により各相ごとに行っており、背面側のユニット34の接続端子55の反転は、その電線を半回転分ねじることを伴って行われるようになっている。
【0029】
このように本構成のものでは、前記基本構造を含んで、ユニット34を箱体51の正面側と背面側との両方に有する両面形のコントロールセンタにおいて、その両ユニット34間の中間部に設けた共通の母線52に両ユニット34を正しく接続できるもので、それにより、従来のもののような個別の母線16を必要とすることはない。従って、母線数の削減ができるものであり、又、母線52を個別に組み付けるような手間も省くことができる。
【0030】
【発明の効果】
本発明は以上説明したとおりのもので、ユニットの主回路機器の各差込受端子に接続導体を差し込むだけで、主回路機器相互の接続がなされ、従来の、電線の端部を主回路機器の各接続端子に逐一ねじ締めしていたもののような手間を要しないので、接続の作業を容易化でき、所要時間も短縮できる。
又、ユニットを箱体の正面側と背面側との両方に有する両面形において、両ユニットの接続端子を、共通の母線の相の並びと位置とに合うように調整し、この状態で、その各接続端子を母線に接続できるので、母線を共通化できて、必要な母線数の削減ができ、且つ、母線を個別に組み付けるような手間も省くことができる。

Further, the connection terminals of each unit of the double-sided type are adjusted so as to match the arrangement and position of the phases of the common bus bars, and in this state, the connection terminals can be connected to the common bus bars.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the basic structure of the present invention will be described with reference to FIGS.
First, FIG. 3 shows a box 31 that is an outer shell of the entire control center. A unit chamber 32 having a plurality of upper and lower stages (three stages in the drawing) and a vertical wiring processing chamber 33 common to these units are arranged on the left and right sides. It has side by side. Each unit chamber 32 accommodates a unit 34 (only the middle unit chamber 32 is shown). The unit 34 includes a circuit breaker 35, an electromagnetic contactor 36, an overload relay 37, and a disconnector 38. In this case, the main circuit devices are attached to a unit frame (not shown) in a side-by-side state.
[0014]
The disconnector 38 includes a unit side 38a and a load side 38b detachably connected to the unit side 38. The unit 34 has only the unit side 38a, and the load side 38b is a vertical wiring. It is fixed in the processing chamber 33. In addition, the unit 34 also integrally includes a monitoring / control device 39 having various display units and operation units.
[0015]
Therefore, the main circuit device (35 to 38) of the unit 34 is provided with the insertion receiving terminal 40 shown in FIG. 1 as a connection terminal for connecting the main circuit devices. The insertion receiving terminal 40 is formed, for example, by bending a single metal plate to form a triangular portion 40a in a generally square shape, and two contacts that extend in the same way from the apex of the triangular portion 40a to the front. Part 40b is formed, and further, two widened piece parts 40c extending in an oblique direction away from the tip part of the contact part 40b are formed, and the electromagnetic contactor 36 side end part of the circuit breaker 35, Expanded piece portions 40c are provided in front of the circuit breaker 35 side end of the magnetic contactor 36, the overload relay 37 side end of the overload relay 37, and the overload relay 37 side end of the unit side 38a of the disconnector 38, respectively. For each, three phases are provided.
The electromagnetic contactor 36 and the overload relay 37 are integrally connected and connected in advance by another means.
[0016]
On the other hand, in FIG. 3, 41 indicates a first connection conductor, and 42 indicates a second connection conductor. Of these, the first connection conductor 41 is shown in detail in FIG. It forms a strip shape, and the insulating coating 43 is applied by coating, for example, leaving both ends.
[0017]
Three first connection conductors 41 are used, and both end portions of the bare connection are inserted into the insertion receiving terminals 40 of the circuit breaker 35 and the electromagnetic contactor 36. At this time, the first connecting conductor 41 is inserted from the side of the expanded piece portion 40c of each insertion receiving terminal 40, and the contact portion 40b is pushed and pressed between the contact portions 40b, whereby the elasticity of the contact portion 40b is obtained. Due to the restoring force, the contact portion 40b is in contact, and thus the circuit breaker 35 and the electromagnetic contactor 36 are connected.
[0018]
On the other hand, as shown in FIG. 1, the second connection conductor 42 is formed by collectively covering three wires with an insulator 44, and the insulator 44 includes, for example, the second connection conductor 42. Inserted and molded in a rectangular parallelepiped block shape, both end portions of the second connection conductor 42 are projected from both left and right side surfaces thereof. In addition, a handle 45 is integrally provided on the front surface of the insulator 44 by molding or another insert part.
[0019]
With this configuration, the second connection conductor 42 has a handle 45, and both ends of the second connection conductor 42 are inserted into the insertion receiving terminals 40 of the overload relay 37 and the disconnector 38. Also at this time, the second connection conductor 42 is inserted from the side of the expanded piece portion 40c of each insertion receiving terminal 40, and the contact portion 40b is pushed and pressed between the contact portions 40b, whereby the contact portion 40b. The elastic restoring force is in contact with the contact portion 40 b, thus connecting the overload relay 37 and the disconnector 38.
[0020]
As shown in FIG. 3, a load connection terminal 46 is provided on the load side 38 b of the disconnector 38. The connection terminal 46 has a length that is shortened in order from the uppermost one to the lowermost one, and an electric wire 47 for connecting a load such as a motor, a resistor, and a lighting fixture is connected to each tip. The box 31 is passed through the vertical wiring processing chamber 33 from below and is connected in a substantially vertical shape.
As is clear from this, the uppermost connection terminal 46 is the introduction destination side of the electric wire 47 , and the lowermost connection terminal 46 is the introduction source side of the electric wire 47 . Of the main circuit devices of the unit 34, the disconnector 38 and the overload relay 37 are adjacent main circuit devices.
[0021]
Now, in the case of the one configured as described above, the connection between the main circuit devices of the unit 34 is made only by inserting the connection conductors 41 and 42 into the respective insertion receiving terminals 40 of the main circuit device. Since the end of the wires 11 and 12 is screwed to the connection terminals 7, 8, 9, and 10 of the main circuit equipment one by one, it is not necessary to perform the work, so the connection work can be facilitated and the time required is shortened. it can.
[0022]
If the second connection conductor 42 is removed from the insertion receiving terminal 40 with the handle 45, the unit 34 is disconnected from the load side, and the operation can be checked. Therefore, when checking the operation of the unit 34, the conventional unit 6 can be performed without the need to pull out the unit 6 until the disconnector 5 is disengaged between the unit side 5a and the load side 5b. In addition, less force is required, and the complicated structure required to hold the conventional unit 6 in the pull-out position is not required.
[0023]
In addition, regarding the connection of the electric wire 47 for connecting the load, the length of the connection terminal 46 for connecting the load of the disconnector 38, which is the connection partner, is shortened in order from the top to the bottom. As a result, the connection positions of the electric wires 47 become different in the lateral direction, and the electric wires 47 can be connected to them while remaining in a generally straight line shape. Therefore, the connection of the electric wire 47 can be performed without requiring the trouble of bending the end portion of the electric wire 14 in the related art, and further, there is a concern about the elastic restoring force at the end portion of the bent electric wire 14. The risk of damage can be eliminated for the connection terminal 46.
[0024]
4 and 5 show an embodiment of the present invention. The same parts as those in the basic structure are denoted by the same reference numerals, the description thereof is omitted, and only different parts are described.
In this case, the box body 51 is equivalent to the above-described two box bodies 31 provided in a so-called back-to-back state, the left side unit chamber 32 on the front side (lower side in the figure), and the rear side (in the figure). By storing the units 34 in both the upper unit chamber 32 on the right side, a double-sided control center is obtained.
[0025]
In this case, a bus bar (vertical bus bar) 52 common to both units 34 is provided side by side in the left-right direction for three phases at the center of the box 51 which is an intermediate part between the units 34.
On the other hand, a groove 54 extending in the left-right direction is provided as a slide guide portion on the back surface of the unit frame 53 shown in FIG. 5 of each unit 34, and the connection for connecting to the bus 52 is connected to the groove 54. A slide base 56 to which terminals 55 are attached for three phases is assembled so as to be slidable and detachable.
[0026]
Here, the bus 52 is an R phase, an S phase, and a T phase in order from the left. Accordingly, in connection with this, the connection terminals 55 of both units 34 also need to be arranged in the R, S, T phase in order from the left, but the connection terminals 55 of the unit 34 on the back side (upper side in the figure) When viewed from the back side, it is necessary to arrange the opposite T, S, and R phases from the left.
[0027]
Therefore, the connection terminals 55 of the unit 34 on the back side are assembled in the groove 54 with the slide base 56 and the left and right reversed, that is, the right and left are reversed. Then, each connection terminal 55 of both units 34 is slid along the groove 54 along the groove 54 in the direction in which the bus bar 52 is positioned. Therefore, in this case, the connection terminal 55 of the rear unit 34 is inverted between the front side and the original side in the sliding direction.
[0028]
Thus, the connection terminals 55 of both units 34 are adjusted to match the arrangement and position of the phases of the busbars 52. In this state, both units 34 are pushed in and the connection terminals 55 are sandwiched between the busbars 52 and connected. . The connection of the connection terminal 55 to the main circuit equipment inside the unit 34, particularly to the circuit breaker 35, is performed for each phase by, for example, an electric wire (not shown) passing through the groove 54 from the slide base 56, and the rear surface.
