の間にコイルバネを設けた端子台が記載されている。[0003] Expanding the technical field and looking at the prior art of a terminal block for simply connecting electric wires to each other, see Japanese Patent Publication No. 4-11988.
In Japanese Unexamined Patent Publication (Kokai) No. Hei 3-7031, there is described a terminal block in which a vertical piece is provided integrally with a terminal fitting, and a coil spring is provided between the tip of the vertical piece and the housing.

イルバネを圧縮した状態のまま、横から挿入しなければ
ならないので、組立作業が容易でなく、組立の自動化が
困難であるという欠点がある。If the automatic return structure of the terminal block is to be used for a control element such as a push button switch, the coil spring is located at the lower part of the vertical piece, so that a space of a compressed coil spring length is required. As a result, the height of the contact portion increases, in other words, the total depth of the push button switch and the like increases. This is a disadvantage in that the commercial value of the control element, for which there is a strong demand for miniaturization, is greatly reduced. Further, in the manufacturing process, since the coil spring must be inserted from the side while being compressed, there is a disadvantage that the assembling work is not easy and it is difficult to automate the assembling.

構造の端子台が記載されている。In Japanese Utility Model Publication No. 3-7031 described above, a compression coil spring is provided on the front side (terminal screw side) of the terminal fitting, and an insertion portion for supporting the center of the coil spring is inserted from the front to the back of the terminal fitting. A terminal block having a structure for supporting a terminal screw is described.

という欠点がある。However, in the automatic return structure of the terminal block, since the insertion portion projects to the back side of the terminal fitting in a state where the terminal screw is tightened, if the present invention is diverted to a control element, the overall depth still remains. There is a drawback that the length is longer, and furthermore, since the coil spring is exposed on the surface of the terminal fitting, there is a drawback that the connection electric wire or the crimp terminal is sandwiched between the springs.

をいう。[0007] Recently, a demand for a control element or a control device, which is increasing, is a finger protection structure. This refers to a structure protected by an insulator so that it is difficult to touch the finger, since there is a danger of electric shock when touching the finger if the energized portion such as the head of the terminal screw is protruded.

There is a method of fixing finger protection pieces 38, 38 covering the heads of the terminal screws 34, 34 by bonding or the like. However, any of the methods has a drawback that the number of parts increases, and in particular, the method of providing the finger protect cover 36 has a drawback that the finger protect cover 36 falls off or is forgotten to be mounted once removed.
