In the state where the symbol display body 3 is in this posture, the moment acting around the central axis of the hinge portions 21 and 21 due to the weight of the symbol display body 3 works in the clockwise direction toward the paper surface in FIG. Is a peripheral portion of the end portion 314 including the concave portion 313, and is fitted between the holding portion 22 and the forming portion of the hinge portion 21, so that it rotates clockwise toward the paper surface in FIG. I can't. Therefore, the state of this posture of the symbol display body 3 is stably maintained. In this state, the display content of the terminal symbol nameplate 37 of the display body 31 can be easily visually confirmed.

しかし、この姿勢の状態は、図１（ｂ）に例示されているように、記号表示体３は設定用スイッチ８の上方を覆っているので、設定用スイッチ８の設定操作を行うことは困難である。端子台１では、設定用スイッチ８の設定操作を行う場合には、記号表示体３を図３に例示されている待避位置の状態に容易に変更できる。記号表示体３の待避位置への変更は、まず、孔部３４とヒンジ部２１とを組み合わせた状態のままで、記号表示体３を図２における紙面に向かって反時計方向に回転させる。この状態が図４に例示した状態である。記号表示体３の前記反時計方向の回転動作を図３に例示した状態からさらに進め、表示体部３１の面３１１などが基台２の背面にほぼ平行する状態の姿勢にする。この姿勢の状態で記号表示体３を下向き移動させる。この場合のヒンジ部２１と支持部３３との組み合わせ状態を、支持部３３の視点から説明すると、ヒンジ部２１は孔部３４から溝部３６に沿って移動し、孔部３５と組み合わされる状態となってその移動は終了する。   However, in this posture state, as illustrated in FIG. 1B, since the symbol display body 3 covers the upper side of the setting switch 8, it is difficult to perform the setting operation of the setting switch 8. It is. In the terminal block 1, when the setting operation of the setting switch 8 is performed, the symbol display body 3 can be easily changed to the state of the retracted position illustrated in FIG. In order to change the symbol display body 3 to the retracted position, first, the symbol display body 3 is rotated counterclockwise toward the paper surface in FIG. 2 while the hole 34 and the hinge portion 21 are combined. This state is the state illustrated in FIG. The counterclockwise rotation operation of the symbol display body 3 is further advanced from the state illustrated in FIG. 3 so that the surface 311 of the display body portion 31 is substantially parallel to the back surface of the base 2. In this state, the symbol display body 3 is moved downward. The combination state of the hinge portion 21 and the support portion 33 in this case will be described from the viewpoint of the support portion 33. The hinge portion 21 moves from the hole portion 34 along the groove portion 36 and is combined with the hole portion 35. The movement ends.

この状態が図３に例示した状態である。設定用スイッチ８の設定操作が完了した以降の適時に、端子台１は記号表示体３の姿勢を図１，図２に例示されている通常位置に戻すことになるが、記号表示体３の姿勢の図３に例示した待避位置から通常位置への変更は、前記した通常位置から待避位置への変更の手順に対して、逆の手順によって行うことができる。なお、この際に、凹部３１３を基台２の凸部２２１に嵌め合わせるべく、表示体部３１を端部３１４から保持部２２とヒンジ部２１の形成部との間に挿入させる必要があるが、表示体部３１の凹部３１３と隣接する角部に面取り部３１５が形成されていると、この表示体部３１の挿入を容易にすることができる。
前述の説明では、端子記号銘板３７は紙製であり、端子記号は印刷法により表示され、裏面に形成された接着剤層により表示体部３１に装着されるとしてきたが、これに限定されるものではなく、例えば、端子記号銘板の材質，端子記号の表示方法，表示体部への装着方法などについては、各種の銘板類に既に採用されている周知の方法を適用することであってもよい。また、表示体部３１などの表示体部に直接に彫刻法により，あるいは記号表示体３がプラスチック材製である場合にはその成形時に端子記号も同時に成形によって形成するなどの周知の適宜の方法を用いて表示することであってもよいものである。 This state is the state illustrated in FIG. At a suitable time after the setting operation of the setting switch 8 is completed, the terminal block 1 returns the posture of the symbol display body 3 to the normal position illustrated in FIGS. The change of the posture from the retracted position illustrated in FIG. 3 to the normal position can be performed by reversing the procedure for changing the normal position to the retracted position. At this time, in order to fit the concave portion 313 to the convex portion 221 of the base 2, it is necessary to insert the display body portion 31 from the end portion 314 between the holding portion 22 and the forming portion of the hinge portion 21. When the chamfered portion 315 is formed at the corner adjacent to the concave portion 313 of the display body portion 31, the display body portion 31 can be easily inserted.
In the above description, the terminal symbol nameplate 37 is made of paper, the terminal symbol is displayed by a printing method, and is attached to the display body portion 31 by the adhesive layer formed on the back surface. For example, as for the material of the terminal symbol nameplate, the method of displaying the terminal symbol, and the mounting method to the display body, it is possible to apply known methods already adopted for various nameplates. Good. In addition, a well-known appropriate method such as forming a terminal symbol by molding at the same time by engraving directly on the display body portion such as the display body portion 31 or when the symbol display body 3 is made of a plastic material. It may be displayed by using.
