Description

本発明は、制御盤前面部へ電磁リレーを高密度に実装するための制御盤配線用リレーアダプタに関するもので、特に、電磁リレーに接続されるケーブルの接続関連構成を制御盤背面側に移行する機構に関する。   The present invention relates to a relay adapter for wiring a control panel for mounting electromagnetic relays on a front surface of a control panel with high density, and in particular, a connection related configuration of a cable connected to the electromagnetic relay is shifted to the back side of the control panel. Regarding the mechanism.

近年、プログラマブルコントローラによる制御盤内のリレー回路のソフトウェア化が進んできた。一方、プログラマブルコントローラは電解コンデンサ等の寿命品を搭載しているため、信頼性の高いスペックが要求される鉄道・変電所等の制御盤においては、プログラマブルコントローラを多重化するか、コイルとマグネットで機械的に接点を動作させる電磁リレーのみで構成するリレー回路が採用されてきた。
プログラマブルコントローラを多重化するのは、同機能の機器を複数配備すること、故障時に制御を切り替えるソフトウェアが必要なことから、高コストになる傾向があり、電磁リレーのみで低コストでリレー回路を構成する盤が多く導入されている。
In recent years, software for relay circuits in a control panel using a programmable controller has progressed. On the other hand, programmable controllers are equipped with electrolytic capacitors and other long-lived products, so in control panels such as railways and substations where highly reliable specifications are required, the programmable controllers can be multiplexed or coils and magnets can be used. A relay circuit composed only of an electromagnetic relay that mechanically operates a contact has been adopted.
Multiplexing programmable controllers requires the deployment of multiple devices with the same function and the need for software that switches control in the event of a failure, so it tends to be expensive, and the relay circuit is configured at low cost using only electromagnetic relays. Many boards have been introduced.

しかし、電磁リレー回路はプログラマブルコントローラと比較して広い設置スペースが必要なため、変電所内の限られたスペース内に盤を収納できなくなる等の問題が生じるケースがあった。
この問題を解決するために、従来、ソケット背面部にケーブルの端子接続部を有する専用の電磁リレーソケットを設け、電磁リレーのコイルおよび接点に接続する多数のケーブルの接続関連構成を盤背面側のデッドスペースに移行させる手段が採用されていた。
However, since the electromagnetic relay circuit requires a larger installation space than the programmable controller, there has been a case in which the board cannot be stored in a limited space in the substation.
In order to solve this problem, conventionally, a dedicated electromagnetic relay socket having a cable terminal connection portion is provided on the back surface of the socket, and a connection-related configuration of a large number of cables connected to the coils and contacts of the electromagnetic relay is provided on the back side of the panel. Means to move to the dead space were adopted.

特許第2508369号公報Japanese Patent No. 2508369

For this reason, there is a problem in that a plurality of cables are scattered around the control panel rear side, requiring a space.

本発明における制御盤配線用リレーアダプタは、制御盤の前面側に配設される電磁リレーと電気的に接続されるケーブルを前記制御盤の背面側に敷設するための接続端子部を有し、前記制御盤の背面側に配設されるリレーアダプタ本体と、前記制御盤の前面側に配設される前記電磁リレーの端子と電気的に接続されて前記制御盤の前面側から前記制御盤の背面側へ延在する導通部材とを備え、前記導通部材を前記リレーアダプタ本体の前記接続端子部と電気的に接続することを特徴とする。   The relay adapter for control panel wiring in the present invention has a connection terminal portion for laying on the back side of the control panel a cable electrically connected to an electromagnetic relay disposed on the front side of the control panel, The relay adapter main body disposed on the back side of the control panel and the electromagnetic relay terminal disposed on the front side of the control panel are electrically connected to the control panel from the front side of the control panel. And a conductive member extending to the back side, wherein the conductive member is electrically connected to the connection terminal portion of the relay adapter body.

本発明における制御盤配線用リレーアダプタによれば、制御盤の前面側に配設される電磁リレーと電気的に接続されるケーブルを制御盤の背面側で接続して敷設することができることにより、制御盤の背面側でケーブルを具合よく配置することができ、制御盤背面における作業性が向上するとともに、前記電磁リレーは一般的な構成で足りるためコスト面での負担も軽減できる。   According to the relay adapter for control panel wiring in the present invention, it is possible to connect and lay the cable electrically connected to the electromagnetic relay disposed on the front side of the control panel on the back side of the control panel, Cables can be arranged well on the back side of the control panel, so that workability on the back side of the control panel can be improved and the electromagnetic relay can be of a general configuration, so that the cost burden can be reduced.
