【考案の詳細な説明】
この考案は、小形電気計器あるいは継電器などに使用さ
れる複数個の端子を有するノックアウト方式の端子箱に
関するものである。[Detailed Description of the Invention] This invention relates to a knockout type terminal box having a plurality of terminals used in small electric meters or relays.
小形電気計器類に使用する端子箱は、類似の各種小形電
気計器に使用できるようにするために、端子箱の内、一
部分の端子は必要に応じて後で端子ねじが追加できるよ
うに、ノックアウト部が作られているものが多く使用さ
れている。Terminal boxes used for small electric meters are designed so that they can be used for various similar small electric meters.Some of the terminals in the terminal box are knocked out so that terminal screws can be added later if necessary. Many of them are used.
即ち、従来の端子箱は、余分の端子部分をノックアウト
方式にし、端子ねじを使用しない場合は端子箱の端子ね
じ用穴部分をノックアウト部でふさいだ構造まま使用し
、端子が追加になる場合に、端子ねじを挿入する際前も
って端子台のノックアウト部分を工具で穴あけした後端
子ねじを取付けるようにしていた。In other words, in conventional terminal boxes, the extra terminals are knocked out, and when terminal screws are not used, the holes for the terminal screws in the terminal box are used as they are with the knockouts blocked, and when additional terminals are added, When inserting a terminal screw, the knockout part of the terminal block was first drilled with a tool, and then the terminal screw was installed.
しかるに上記のように構成した従来の端子箱は、端子が
追加になる都度端子台のノックアウト部分を穴あけしな
ければならず、また、一旦電気計器が組立てられてしま
うと、計器を分解してから端子台を加工する必要があり
、非常に面倒な作業になっていた。However, with the conventional terminal box configured as described above, the knockout part of the terminal block must be drilled each time a terminal is added, and once the electric meter is assembled, the meter must be disassembled and then removed. It was necessary to process the terminal block, which was a very troublesome task.
この考案は上記のような従来のものの欠点を除去するた
めになされたもので、組立てられた電気計器の端子箱に
端子を追加する場合でも、また、新たに組立てる場合で
も、端子箱を組立てる際自動的にノックアウト部分が除
去できるようにした端子箱を提供することを目的として
いる。This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above, and whether it is adding a terminal to the terminal box of an assembled electric meter or assembling a new one, it is easy to assemble the terminal box. The object of the present invention is to provide a terminal box whose knockout portion can be automatically removed.
以下、この考案の一実施例を図について説明する。An embodiment of this invention will be described below with reference to the drawings.
第１図ないし第３図において、１は端子箱である。In FIGS. 1 to 3, 1 is a terminal box.
２は端子台であって絶縁物で作られている。2 is a terminal block made of an insulating material.
２Ａは上記端子台に設けられた固定穴である。2A is a fixing hole provided in the terminal block.
２Ｂは端子台２のナツト固定穴であって、後述の六角ナ
ツト３が回転しないように六角の形状をしている。2B is a nut fixing hole of the terminal block 2, which has a hexagonal shape so that a hexagonal nut 3, which will be described later, does not rotate.
３は六角ナツトであって、中心部はねじになっており上
述のナツト固定穴２Ｂにはめ込まれている。3 is a hexagonal nut, the center part of which is threaded, and is fitted into the above-mentioned nut fixing hole 2B.
４は導電材で作られた接続片であって、第３図に示すよ
うに、機器内部のリード線５と外部リード線６を電気的

入し、折曲げ固定されている。Reference numeral 4 denotes a connecting piece made of a conductive material, which electrically connects the lead wire 5 inside the device and the external lead wire 6, as shown in FIG. Insert it, bend it and fix it.
７は端子ねじであって、首下部７Ａ、ねじ部７Ｂ、先端
部７Ｃを有し、ねじ部７Ｂは上述の接続片４の中心部の
穴を通してナツト３にねじ込まれている。A terminal screw 7 has a lower neck portion 7A, a threaded portion 7B, and a tip portion 7C, and the threaded portion 7B is screwed into the nut 3 through a hole in the center of the connection piece 4 described above.
先端部７Ｃは、端子台２の穴部２Ｃに入り込むように形
成されると共に、上述の端子台２のノックアウト部２Ｄ
に対応した位置にあり、端子ねじ７をねじ込むと、第３
図に示すように端子ねじ７の先端部７Ｃがノックアウト
部２Ｄを押し出すように作られている。The tip portion 7C is formed so as to fit into the hole 2C of the terminal block 2, and also fits into the knockout portion 2D of the terminal block 2 described above.
When the terminal screw 7 is screwed in, the third
As shown in the figure, the tip portion 7C of the terminal screw 7 is made to push out the knockout portion 2D.
このように構成した端子箱について次にその作用を説明
する。The operation of the terminal box constructed in this way will be explained next.
端子ねじ７を締付けるまでは、第２図のように端子台２
のノックアウト部２Ｄは端子台と一体に付いている。Until the terminal screw 7 is tightened, the terminal block 2
The knockout part 2D is attached integrally with the terminal block.
次に端子ねじ７をねじ込むと、端子ねじ７が第３図のよ
うに矢印方向（図示右方向）に移動し、先端部７Ｃがノ
ックアウト部２Ｄに接触する。Next, when the terminal screw 7 is screwed in, the terminal screw 7 moves in the direction of the arrow (to the right in the figure) as shown in FIG. 3, and the tip end 7C comes into contact with the knockout part 2D.
更に端子ねじ７を締め込むと、第３図のように、端子ね
じ７の先端部７Ｃがノックアウト部２Ｄを突き破る。When the terminal screw 7 is further tightened, the tip portion 7C of the terminal screw 7 breaks through the knockout portion 2D, as shown in FIG.
以上この考案による端子箱によれば、端子ねじを使用１

部を穴あけする必要が無く工事が非常に簡単となる効果
がある。According to the terminal box according to this invention, terminal screws are used.
．． When not in use, the holes are covered with knockouts to prevent dust from entering through the screw holes in terminal box 1, and when terminal screws are used, the knockout portions of the terminal block are naturally pierced by the terminal screws, preventing additional damage. There is no need to drill a hole in the knockout part in advance, making the construction work very simple.
