Description

本発明は、操作ハンドルの動作を規制して回路遮断を行わないハンドルロックの構造に関するものである。   The present invention relates to a handle lock structure that restricts the operation of an operation handle and does not interrupt the circuit.

回路遮断器21のハンドルロック22は、回路遮断器21とは別部品で形成され、例えば、略T字状にロック部22aと係止部22bとを形成していた。回路遮断器21の操作ハンドル23の側面からロック部22aを差し込んで、係止部22Bを回路遮断器21の側面に係止させ、回路遮断器21の操作ハンドル23がONの状態の時に、操作ハンドル23の動作を規制するように操作ハンドル23をロック部22aに係止させていた。

The handle lock 22 of the circuit breaker 21 is formed as a separate part from the circuit breaker 21. For example, a lock portion 22a and a locking portion 22b are formed in a substantially T shape. The lock portion 22a is inserted from the side surface of the operation handle 23 of the circuit breaker 21, and the locking portion 22B is locked to the side surface of the circuit breaker 21, so that the operation is performed when the operation handle 23 of the circuit breaker 21 is ON. The operation handle 23 is locked to the lock portion 22a so as to restrict the operation of the handle 23.
Kawamura Catalog Electric Materials No. 34 Revised May 1, 2003

ハンドルロック22が回路遮断器21の外付けである別部品であるため、部品管理が煩雑なものとなっていた。また、ハンドルロック22を回路遮断器21に取り付けたとき、ハンドルロック22の分だけ、回路遮断器21の外形寸法が大きくなってしまうため、分電盤に組み込むときには、都度ハンドルロック22を考慮に入れ設計する必要があり、手間がかかっていた。   Since the handle lock 22 is a separate part externally attached to the circuit breaker 21, the part management is complicated. Further, when the handle lock 22 is attached to the circuit breaker 21, the outer dimensions of the circuit breaker 21 are increased by the handle lock 22. Therefore, the handle lock 22 must be taken into consideration each time it is incorporated into the distribution board. It was necessary to design the case, and it took time and effort.

本発明は、外形寸法を変えることなく、回路遮断器の操作ハンドルをロックできるハンドルロックの構造を提供することを目的とし、その構造は、ハンドルロック部品を回路遮断器の操作ハンドル近傍に内蔵し、操作ハンドルがハンドルロック部品によりONの位置で係止されるようにハンドルロックを施すことを特徴とする。   It is an object of the present invention to provide a handle lock structure that can lock an operation handle of a circuit breaker without changing an external dimension, and the structure includes a handle lock component in the vicinity of the operation handle of the circuit breaker. The handle is locked so that the operation handle is locked at the ON position by the handle lock part.

本発明に係るハンドルロックは、ハンドルロックを回路遮断器に内蔵し、回路遮断器の外形寸法を変化させずにハンドルロックすることができるため、ハンドルロックが必要かどうかによって設計し直すというような手間を省くことができる。ハンドルロックの部品管理も不要となり部品管理の煩雑さから解放される。   Since the handle lock according to the present invention has a handle lock built in the circuit breaker and can be locked without changing the external dimensions of the circuit breaker, it is redesigned depending on whether the handle lock is necessary. Save time and effort. The part management of the handle lock is not necessary, and the part management is free from complexity.

また、本発明の請求項2に係るハンドルロックは封印可能な構造であるため、主幹ブレーカのハンドルロックにも適用できる。   Further, since the handle lock according to claim 2 of the present invention has a sealable structure, it can also be applied to the handle lock of the main breaker.

回路遮断器にハンドルロックを施すという目的を、簡単な構造で回路遮断器の外形寸法を変化させることなく実現した。   The purpose of providing a handle lock on the circuit breaker was achieved with a simple structure and without changing the external dimensions of the circuit breaker.

本発明に係るハンドルロックの構造を図1〜図3の添付図面に基づいて説明する。   The structure of the handle lock according to the present invention will be described with reference to the accompanying drawings of FIGS.

ハンドルロック部品1はロック部1aにレバー部1bを突出させた形状である。回路遮断器2の操作ハンドル3の近傍にスライド穴4を設け、このスライド穴4からレバー部1bを突出させてスライド移動可能に、ハンドルロック部品1を回路遮断器2に内蔵する。   The handle lock part 1 has a shape in which a lever portion 1b is protruded from a lock portion 1a. A slide hole 4 is provided in the vicinity of the operation handle 3 of the circuit breaker 2, and the handle lock part 1 is built in the circuit breaker 2 so that the lever portion 1 b protrudes from the slide hole 4 and can be slid.

ハンドルロック部品1は、回路遮断器2の操作ハンドル3の近傍に取り付けられ、通常の使用状態の時には、ハンドルロック部品1は回路遮断器2の内部に収められ、ロック時には、ハンドルロック部品1をスライド移動させ、ロック部1aに操作ハンドル3を係止させるようにして、ロック部1aが操作ハンドル3の動作を規制し、操作ハンドル3がOFFの状態にならないようにすることで、ハンドルロックを施すものである。   The handle lock part 1 is attached in the vicinity of the operation handle 3 of the circuit breaker 2, and the handle lock part 1 is housed inside the circuit breaker 2 during normal use, and the handle lock part 1 is locked when locked. By sliding and moving the lock handle 1a to lock the operation handle 3, the lock portion 1a restricts the operation of the operation handle 3 so that the operation handle 3 is not turned off. It is something to apply.

従来のハンドルロックのように、回路遮断器の外側から差し込むものと違い、ハンドルロックをする場合、しない場合どちらも回路遮断器の外形寸法が変化することがなく、回路遮断器2を並列する場合にも、回路遮断器2の側面全面を接合することができる。また、部品の追加がなく、作業性もよい。   Unlike the case where a conventional handle lock is inserted from the outside of the circuit breaker, the case where the handle is locked and the case where both do not change the external dimensions of the circuit breaker and the circuit breaker 2 is arranged in parallel. In addition, the entire side surface of the circuit breaker 2 can be joined. Moreover, there is no addition of parts and workability is good.

回路遮断器2に設けられたスライド穴4近傍には封印穴5を有する封印フック6を形成する。ハンドルロックした時に封印フック6にハンドルロック部品1のレバー部1bを接近させ、レバー部1bと封印フック6の封印穴5とに封印線7を挿通し外れないように封印し、封印した後は、誤ってハンドルロックが動いて回路遮断器2が作動することがないようにできる。   A sealing hook 6 having a sealing hole 5 is formed in the vicinity of the slide hole 4 provided in the circuit breaker 2. After the handle is locked, the lever 1b of the handle lock part 1 is brought close to the seal hook 6, and after sealing the seal 1 so that the seal wire 7 is not inserted and removed from the lever 1b and the seal hole 5 of the seal hook 6. It is possible to prevent the circuit breaker 2 from operating due to an accidental movement of the handle lock.

回路遮断器をハンドルロックする場合、内蔵されているハンドルロックを動かすだけでよく、小さい箱体に回路遮断器を組み込んで構成された分電盤等で作業性を向上することができる。   When the circuit breaker is handle-locked, it is only necessary to move the built-in handle lock, and workability can be improved with a distribution board configured by incorporating the circuit breaker into a small box.
