Description

本発明は電気機器用ケーブルとネジ式端子台の間に接続する部品に関する分野である。 The present invention is in the field of components that connect between electrical equipment cables and screw terminal blocks.

電気機器用ケーブル１２をネジ式端子台１０に接続する場合、丸型端子もしくはＹ型端子と呼ばれる圧着端子を圧着機と呼ばれる専用工具を用いて、電気機器用ケーブル１２と圧着端子を接続した上でネジ式端子台１０に電気機器用ケーブル１２を接続する。 When connecting the electric device cable 12 to the screw terminal block 10, a crimp terminal called a round terminal or a Y-shaped terminal is connected to the electric device cable 12 using a special tool called a crimping machine. , the electrical equipment cable 12 is connected to the screw type terminal block 10 .

上記圧着機と呼ばれる専用工具が不要となる方法として、ワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台を使用する方法がある。 As a method that does not require a special tool called a crimping machine, there is a method that uses a terminal block called a one-touch type, a screwless type, or a set screw type.

しかしながら既存の生産設備等において既にネジ式の端子台１０が取り付けられており圧着端子を用いた電気機器用ケーブル１２の接続が完了している場合、ワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台へ変更するためには、全ての接続済み電気機器用ケーブル１２をネジ式の端子台１０から取り外し、ワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台へ端子台を変更する作業を行った後、再び全ての電気機器用ケーブル１２を接続し直さなければならない。この作業に多くの時間を要し、誤接続を起こす問題もあり変更作業は大変困難である。 However, when the screw type terminal block 10 is already installed in the existing production equipment and the connection of the electrical equipment cable 12 using the crimp terminal is completed, the terminal called the one-touch type, the screwless type, or the set screw type is used. In order to change to a base, all the connected electrical equipment cables 12 were removed from the screw type terminal block 10, and the terminal block was changed to a terminal block called a one-touch type, a screwless type, or a set screw type. Afterwards, all electrical equipment cables 12 must be reconnected. This work takes a lot of time, and there is also the problem of incorrect connection, making the change work extremely difficult.

また、ワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台を既存の生産設備等に取り付けられるスペースが確保できるかという問題がある。 Also, there is a problem of whether a space can be secured for mounting a terminal block called a one-touch type, a screwless type, or a set screw type to existing production equipment or the like.

全ての接続済み電気機器用ケーブル１２ではなく一部の電気機器用ケーブル１２のみネジ式端子台１０から、ワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台へ変更することも考えらるが、ネジ式端子台１０はネジ式端子台全体を一本のネジで一体化して固定しておりネジ式端子台の一部のみを簡単に取り外せないという問題がある。 It is conceivable to change from the screw type terminal block 10 to a terminal block called a one-touch type, a screwless type, or a set screw type, but not for all the connected electric device cables 12, but only for some electric device cables 12. The screw-type terminal block 10 has a problem that the whole screw-type terminal block is integrated and fixed with one screw, and only a part of the screw-type terminal block cannot be easily removed.

ワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台は、電気機器用ケーブルは導体７と絶縁被覆８でできており、電気機器ケーブル１２の絶縁被覆８をワイヤーストリッパーと呼ばれる工具で取り除き導体７を表に出し、導体７をワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台と接続する。 A terminal block called a one-touch type, a screwless type, or a set screw type has a cable for electrical equipment made of a conductor 7 and an insulating coating 8. The insulating coating 8 of the electrical equipment cable 12 is removed by a tool called a wire stripper, and the conductor 7 is removed. The conductor 7 is exposed and connected to a terminal block called a one-touch type, a screwless type, or a set screw type.

しかしながら絶縁被覆８は保持されないため、電気機器用ケーブル１２の荷重はワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台と接続している導体７に全てかかることになり、導体７と絶縁被覆８の境目で断線しやすくなるという問題がある。 However, since the insulating coating 8 is not held, the load of the electrical equipment cable 12 is all applied to the conductor 7 connected to the terminal block called one-touch type, screwless type, or set screw type, and the conductor 7 and the insulating coating 8 There is a problem that disconnection is likely to occur at the boundary between .

課題を解決するための発明は、図１に示すように片側にＹ型端子と呼ばれる導電性の端子形状２もしくは丸型端子と呼ばれる導電性の端子形状３を有し、反対側に電気機器用ケーブル１２の絶縁被覆が取り除かれて表に出ている導体７を接続する導電性バネ５と絶縁被覆８の保持を行うバネ１３を持ち、導体７の接続と絶縁被覆８の保持を同時に行うための導電性バネ５とバネ１３を同時に押し下げる構造６を持ち、構造６は押し下げる箇所に絶縁樹脂１６が取り付けられており、導電性バネ５とバネ１３は絶縁カバー４で覆われており、構造６を押し下げたとき導電性の端子形状２もしくは導電性の端子形状３と絶縁カバー４の間で変形が起きないようネジ式端子台１０へ絶縁カバー４を押し付けて変形を防ぐ形状１１を持ち、さらに導電性の端子形状１もしくは導電性の端子形状２を持った個所と、導体７を接続する導電性のバネ５が電気的に繋がっている部品を提供する。 The invention for solving the problem has a conductive terminal shape 2 called a Y-shaped terminal or a conductive terminal shape 3 called a round terminal on one side as shown in FIG. In order to connect the conductor 7 and hold the insulating coating 8 at the same time by holding the conductive spring 5 that connects the conductor 7 exposed by removing the insulating coating of the cable 12 and the spring 13 that holds the insulating coating 8. In the structure 6, an insulating resin 16 is attached to the part to be pushed down, the conductive spring 5 and the spring 13 are covered with an insulating cover 4, and the structure 6 It has a shape 11 that prevents deformation by pressing the insulating cover 4 against the screw type terminal block 10 so that deformation does not occur between the conductive terminal shape 2 or the conductive terminal shape 3 and the insulating cover 4 when the is pushed down. A part having a conductive terminal shape 1 or a conductive terminal shape 2 and a conductive spring 5 connecting a conductor 7 are electrically connected to each other.

発電所等重要施設で電気配線用にネジ式端子台１０を用いている場合、長時間滞在すると人体に影響がある過酷な環境となるような重大な事故が発生し、その過酷な環境のもとで断線した電気機器用ケーブル１２の復旧や、故障したセンサ類を交換作業しなければならないことが起こったとき、現場で圧着端子および圧着工具を用いる時間的余裕がなく、応急処置として電気機器用ケーブル１２の絶縁被覆８を取り除き導体７を表に出し、導体７をそのままネジ式端子台に接続するということが想定される。この場合導体７に電気機器用ケーブル１２の荷重がかかることになり、電気機器用ケーブルの導体７と絶縁被覆８の境目で断線し再度復旧作業が発生する可能性がある。 When the screw-type terminal block 10 is used for electrical wiring in an important facility such as a power plant, a serious accident may occur in which a severe environment affecting the human body may occur if the user stays there for a long time. When it becomes necessary to restore the cable 12 for electrical equipment that has been disconnected or to replace the failed sensors, there is no time to use crimp terminals and crimping tools at the site, and as an emergency measure, the electrical equipment It is assumed that the insulation coating 8 of the cable 12 is removed to expose the conductor 7, and the conductor 7 is directly connected to the screw terminal block. In this case, the load of the electrical equipment cable 12 is applied to the conductor 7, and there is a possibility that the conductor 7 of the electrical equipment cable and the insulation coating 8 will break at the boundary, and the restoration work will be required again.

自動車や飲料品や半導体の量産ラインの既存の生産設備等にて電気機器用ケーブル１２接続用にネジ式端子台１０を用いている場合、センサ類やエアシリンダーなどのアクチュエータ類の故障が発生したときは、素早い故障部品の交換作業が必要となるが、圧着端子および圧着工具を用いた作業となり生産ラインの停止時間がのびるという問題がある。 When the screw type terminal block 10 is used for connecting the cable 12 for electrical equipment in existing production equipment such as mass production lines for automobiles, beverages, and semiconductors, failure of actuators such as sensors and air cylinders occurs. In some cases, it is necessary to quickly replace the faulty part, but this requires the use of crimp terminals and crimping tools, which poses the problem of longer production line stoppages.

また自動車や飲料品や半導体の量産ラインの既存の生産設備等では、ネジ式端子台１０に接続された全てのセンサ類やエアシリンダーなどのアクチュエータ類において故障の頻度は個別的な差異がある。頻繁に故障する一部のセンサ類やエアシリンダーなどのアクチュエータ類のために、全ての接続済み電気機器用ケーブル１２とネジ式端子台１０を取り外し、ワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台へ変更することは非効率で非現実的である。 In addition, in existing production equipment of mass production lines for automobiles, beverages, and semiconductors, there are individual differences in the frequency of failures in all sensors and actuators such as air cylinders connected to the screw type terminal block 10 . For some sensors and actuators such as air cylinders that frequently fail, remove all the connected electric equipment cables 12 and screw type terminal blocks 10 and connect them to terminals called one-touch type, screwless type, or set screw type. Converting to a pedestal is inefficient and impractical.

この発明は上記の問題を解決する方法を提供する。発明品である電気機器用ケーブルとネジ式端子台の間に接続する部品１を用いることにより、既存の生産設備等に取り付けてあるネジ式端子台１０を交換せずにそのまま使えてなおかつワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台のように配線作業が簡便になることを提供する。 The present invention provides a method to solve the above problems. A screw type terminal block 10 attached to an existing production facility or the like can be used as it is without replacement by using the component 1 connected between the electric equipment cable and the screw type terminal block, which is an invention, and is a one-touch type. Alternatively, a terminal block called a screwless type or a set screw type provides the convenience of wiring work.

発明品である電気機器用ケーブルとネジ式端子台の間に接続する部品１は、電気機器用ケーブル１２の導体７の接続と、絶縁被覆８の保持を同時に行っており、導体７に電気機器用ケーブルの荷重が掛からず断線しにくい利点が生まれる。 The component 1 connected between the electrical equipment cable and the screw terminal block, which is the invention, simultaneously connects the conductor 7 of the electrical equipment cable 12 and holds the insulating coating 8, and the conductor 7 is connected to the electrical equipment. There is an advantage that the load of the cable is not applied and it is difficult to disconnect.

発明品である電気機器用ケーブルとネジ式端子台との間に接続する部品１は、ネジ式端子台１０の中の一か所のみの使用からでも用いることができる。 The component 1 connected between the electrical equipment cable and the screw type terminal block, which is the invention, can be used even if it is used only at one place in the screw type terminal block 10 .

ネジ式端子台１０の中で、発明品である電気機器用ケーブルとネジ式端子台１の間を接続する部品に取り換えた箇所は、取り換えたあと後しばらくして再びセンサ類の故障により配線作業が発生しても、ワンタッチ式あるいはスクリューレス方式あるいはイモネジ式と呼ばれる端子台のように配線作業が簡便になる。 In the screw-type terminal block 10, the part that was replaced with the part that connects between the cable for electrical equipment, which is an invention, and the screw-type terminal block 1 was replaced. Even if this occurs, the wiring work can be simplified with a terminal block called a one-touch type, a screwless type, or a set screw type.
