【発明の属する技術分野】
本発明は,ブッシング端子に取り付ける回路分岐用アダプターに関する。
【0002】
【従来の技術】
従来のブッシング端子は,接続される回路数によりその形状を変更しており,たとえば図3に示すように,外箱6に取り付けられたブッシング1に固定される端子2に1回路のみを接続する場合は,接続端子3が1個取り付けられるような固定穴4を端子2に設けておき、ボルト5にて接続端子3を端子2に固定していた。3回路に分岐する場合は,図4に示すように,ブッシング1に固定される端子2aに接続端子3が同一平面上に3個取り付けられるような固定穴4を設けておき、ボルト5にて接続端子3を端子2aに固定していた。
また,複数の回路数が必要な機器において,機器全体をコンパクトな構造にする必要がある場合は,たとえば図5に示すように,端子2を2個の接続端子3にて挟み込んで固定できるような固定穴4を端子2に設けておき,ボルト5にて2つの接続端子3を端子2に固定していた。
【0003】
【発明が解決しようとする課題】
従来のブッシング端子においては,分岐数を1回路から3回路に変更する場合には,ブッシング端子間の必要なスペースが確保できず,ブッシング端子の配置を変更する必要があるため,機器全体の構造を見直す必要があった。仮に必要なスペースが確保できたとしても,取り付けてあるブッシング端子を取り外し,必要な分岐数のブッシング端子を取り付ける必要があるため,多大な時間を必要としていた。
また,最初から3回路に分岐可能なブッシング端子を取り付ける構造にしてしまうと,1回路しか使用しない場合でも3回路分のスペースが必要になるため,機器自体が大型化してしまうという問題があった。
ブッシング端子を接続端子2個にて挟み込み,ボルトで固定しているものについては,接続端子2個が同一のボルトで固定されていることから,1個の接続端子のみを取り外したい場合でも両方の接続端子を取り外す必要があるため,電気の供給などに支障がきたすおそれがあった。
そこで,本発明では分岐数を1回路から3回路に変更する場合でも,機器全体の構造を見直すことなくかつ取り付け,取り外しが容易なブッシング端子用分岐アダプターを提供することを目的とする。
【0004】
【課題を解決するための手段】
本発明はこれらを解決するため,接続端子との合わせ面がブッシング端子と垂直になるよう下方へ2回路,ブッシング端子と平行になるように上方へ1回路分岐可能な構造であり,かつ接続される3回路分それぞれの接続端子が個々に取り付け,取り外し可能な構造としたことを特徴とする。
このようにすれば,3回路必要な機器についても1回路の機器と同等の寸法にできるほか,それぞれの接続端子が別々に取り付け,取り外し可能となる。
【0005】
【発明の実施の形態】
以下,本発明の実施例を図1および図2により説明する。
図1において、外箱6に取り付けられたブッシング1の端子2には,3回路に分岐可能な分岐アダプター7が取り付けられるような穴を設けておき,その端子2に設けた穴に3回路に分岐可能な分岐アダプター7をボルト5aにて取り付ける。
分岐アダプター7の構造は,図1および図2において,まず接続端子3a,3bの取付面と垂直に位置する面の一方には,ブッシング1の端子2に固定できるように固定ねじ穴8cを設けておく。接続端子3a,3bと端子2との合わせ面同士は互いに向き合うような構造とし,その合わせ面が端子の合わせ面と垂直になり,かつ接続端子3a,3bが別々に固定できるよう固定ねじ穴8a,8bを配置することにより,下部へ2回路配線可能な構造とする。なお,接続端子2aと接続端子2b間の寸法Eは,ボルト5bにて固定できる最小寸法とし,固定ねじ穴8a,8b,8cは,分岐アダプター7を端子2にボルト5aにて取り付けてその分岐アダプター7に接続端子3a,3bをボルト5bにて固定した際に,ボルト5aおよびボルト5b同士が干渉しないよう上下方向にずらして配置(例えば,A寸法>B寸法,A寸法<C寸法でD寸法は各面同一寸法。)するとともに、固定ねじ穴8a,8bについてはもう一方の接続端子取り付け面まで突きでないように配置する。
また,分岐アダプター7の接続端子3a,3b固定部の上側には,接続端子3cとの合わせ面が端子2の合わせ面と平行になるよう固定穴4を配置し,接続端子3cがボルト5Cにて固定できるようにして,上部へ1回路配線可能な構造とする。

BACKGROUND OF THE INVENTION
The present invention relates to a circuit branching adapter attached to a bushing terminal.
[0002]
[Prior art]
The shape of the conventional bushing terminal is changed depending on the number of connected circuits. For example, as shown in FIG. 3, only one circuit is connected to the terminal 2 fixed to the
Further, in a device that requires a plurality of circuits, when it is necessary to make the entire device compact, for example, as shown in FIG. 5, the terminal 2 can be sandwiched and fixed by two connection terminals 3. A
[0003]
[Problems to be solved by the invention]
In the conventional bushing terminal, when the number of branches is changed from one circuit to three circuits, the necessary space between the bushing terminals cannot be secured and the arrangement of the bushing terminals must be changed. It was necessary to review. Even if the necessary space could be secured, it took a lot of time because it was necessary to remove the attached bushing terminals and install the bushing terminals with the required number of branches.
In addition, if a bushing terminal that can be branched into three circuits is attached from the beginning, there is a problem that even if only one circuit is used, a space for three circuits is required, resulting in an increase in the size of the device itself. .
For the bushing terminal that is sandwiched between two connection terminals and fixed with bolts, both connection terminals are fixed with the same bolt, so even if you want to remove only one connection terminal, both Since it was necessary to remove the connection terminal, there was a risk of hindering electricity supply.
Accordingly, an object of the present invention is to provide a bushing terminal branch adapter that can be easily attached and detached without reexamining the structure of the entire device even when the number of branches is changed from one to three.
[0004]
[Means for Solving the Problems]
In order to solve these problems, the present invention has a structure in which two circuits can be branched downward so that the mating surface with the connection terminal is perpendicular to the bushing terminal, and one circuit can be branched upward so as to be parallel to the bushing terminal. The connection terminals for each of the three circuits are individually attached and removable.
In this way, a device that requires three circuits can have the same dimensions as a single-circuit device, and each connection terminal can be attached and detached separately.
