Description

【０００１】
【発明の属する技術分野】
分電盤内で遮断器の端子部と接続されて用いられる端子台を被覆するカバーの取り付け構造に関する。
【０００２】
【従来の技術】
従来技術における端子カバーの取り付け構造は、基台の上部長手方向に溝を形成し、カバーを溝に嵌入して取り付け、カバーの脱着によって開閉していた。また、図４に示すように、基台３１の上端部に挿通孔３２を設け、カバー３３には回転軸３４を形成し、挿通孔３２に回転軸３４を嵌入しカバー３３が回動可能であるように取り付けていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来技術において、溝にカバーを嵌め込む端子カバーの取り付け構造のものは、カバーを開けるときには基台からカバーが離れてしまうため、カバーを紛失する虞があった。また、回転軸３４を挿通孔３２に挿通する形式のものでは、カバー３３を基台３１に取り付けるのが困難であると共に、カバー３３は回動可能であるが、回転規制がないのでカバーを開放したときに他の機器に当たり、開閉作業が煩わしいものとなっていた。それから、基台３１に挿通孔３２を設ける、その金型は、外形を形作る第一、第二の金型と、挿通孔３２を形成するための第三の金型が必要であり、金型費用を引き上げ、製造コストも高くなっていた。
【０００４】
【課題を解決するための手段】
そこで本発明は、簡単な構造で安価に提供でき、端子カバーが容易に基台に取り付けられる端子カバーの取り付け構造を提供することを目的とし、その構造は、端子台の基台側面端部に一定間隔で略Ｕ字状の溝部を突設すると共に、溝部に内側に向かい合わせに爪部を設け、カバーに設けられた回転軸を溝部に挿入し、カバーが回動可能に取り付けることを特徴とする。
【０００５】
また、溝部間の基台側面に軸受け部を設けたことを特徴とする。
【０００６】
【発明の実施の形態】
本発明に係る端子カバー取り付け構造は、端子台の側面上端部に内側に互いに向き合うような爪部を設けたＵ字状の溝部を形成し、カバーに設けられた回転軸を溝部に挿通し、カバーが回動可能であるように基台に取り付ける。回転軸を溝部に挿通するときには、爪部に沿ってカバーが移動する。また、カバーを基台に取り付け、開閉するときには爪部によって開閉角度を規制し、近傍の機器に当たらないように中立の位置で保持される。
【０００７】
また、溝部間の基台側面に軸受け部を設け、溝部に回転軸を挿入するときに、軸受け部が回転軸の動作を助け、円滑にカバーを回転させる。
【実施例】
本発明に係る端子台のカバー取り付け構造の実施例を図１〜図４の添付図面に基づいて説明する。
【０００８】
端子台１は、基台２をカバー３で被覆して構成され、分電盤内で遮断器の端子部と接続して用いる。基台２の側面上端部には、溝部４を形成する。溝部４は、一定間隔をおいて略Ｕ字状に突設され、溝部４は内側に爪部５を形成する。カバー３には回転軸６が形成され、基台２の溝部４に設けられた爪部５に対向する位置に、嵌入溝７を設ける。カバー３に形成された回転軸６を基台２の溝部４に挿通する。
【０００９】
回転軸６を中心に回転させ端子台１を被覆するとき、カバー３は爪部５の曲面に沿って移動し、爪部５が嵌入溝７に嵌めこまれ、取り付けられる。カバー３を開けるときには、爪部５にカバー３の開閉角度が規制され、最大に開けても約１１０°〜１６０°の中立の位置で保持される。
【００１０】
本発明の請求項２に係る端子カバーの取り付け構造は、溝部４の間の基台側面には、軸受け部８を形成する。カバー３の回転軸６は軸受け部８で支持され、円滑にカバー３が回転する。
【００１１】
【発明の効果】
本発明に係る端子台のカバー取り付け構造は、端子台の基台側面端部に一定間隔で略Ｕ字状の溝部を突設すると共に、溝部に内側に向かい合わせに爪部を設け、カバーに設けられた回転軸を溝部に挿入し、カバーが回動可能に取り付けるため、基台をつくるための金型も、従来のように３型は必要なく、２型ですむため、製造コストを引き下げることができる。また、端子カバーの取り付けも容易で作業性も良い。さらには、爪部によってカバーの開閉角度は規制されるので、分電盤内で他の機器に干渉することがない。
【００１２】
また、溝部間の基台側面に軸受け部を設けたため、カバーの回転軸が軸受け部に支持され、円滑にカバーを回転させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a cover mounting structure that covers a terminal block that is connected to a terminal portion of a circuit breaker in a distribution board.
[0002]
[Prior art]
In the conventional terminal cover mounting structure, a groove is formed in the upper longitudinal direction of the base, the cover is fitted into the groove, and is opened and closed by attaching and detaching the cover. As shown in FIG. 4, an insertion hole 32 is provided in the upper end portion of the base 31, a rotation shaft 34 is formed in the cover 33, and the rotation shaft 34 is fitted into the insertion hole 32 so that the cover 33 can be rotated. It was attached as it was.
[0003]
[Problems to be solved by the invention]
However, in the above prior art, the terminal cover mounting structure in which the cover is fitted in the groove has a risk of losing the cover because the cover is separated from the base when the cover is opened. Further, in the type in which the rotating shaft 34 is inserted into the insertion hole 32, it is difficult to attach the cover 33 to the base 31, and the cover 33 can be rotated, but since there is no rotation restriction, the cover is opened. When doing so, it hits other equipment, and the opening and closing work was troublesome. Then, the insertion hole 32 is provided in the base 31, and the mold requires first and second molds for forming the outer shape and a third mold for forming the insertion hole 32. Costs were increased and manufacturing costs were high.

A groove 4 is formed at the upper end of the side surface of the base 2. The groove part 4 is protruded in a substantially U shape at regular intervals, and the groove part 4 forms a claw part 5 inside. A rotation shaft 6 is formed in the cover 3, and a fitting groove 7 is provided at a position facing the claw portion 5 provided in the groove portion 4 of the base 2. The rotating shaft 6 formed in the cover 3 is inserted into the groove portion 4 of the base 2.
[0009]
When the terminal block 1 is covered by rotating around the rotating shaft 6, the cover 3 moves along the curved surface of the claw portion 5, and the claw portion 5 is fitted in the fitting groove 7 and attached. When the cover 3 is opened, the opening and closing angle of the cover 3 is regulated by the claw portion 5 and is held at a neutral position of about 110 ° to 160 ° even when the cover 3 is opened to the maximum.
[0010]
In the terminal cover mounting structure according to claim 2 of the present invention, the bearing portion 8 is formed on the side surface of the base between the groove portions 4. The rotating shaft 6 of the cover 3 is supported by the bearing portion 8, and the cover 3 rotates smoothly.
[0011]
【The invention's effect】
In the terminal block cover mounting structure according to the present invention, a substantially U-shaped groove is projected at regular intervals on the side surface end of the base of the terminal block, and a claw portion is provided facing the inner side of the groove. Insert the rotating shaft into the groove and attach the cover so that it can rotate, so there is no need for the mold for making the base. be able to. Also, the terminal cover can be easily attached and the workability is good. Furthermore, since the opening / closing angle of the cover is regulated by the claw portion, it does not interfere with other devices in the distribution board.
[0012]
Moreover, since the bearing part was provided in the base side surface between groove parts, the rotating shaft of a cover is supported by the bearing part, and a cover can be rotated smoothly.
