【Example】

 An embodiment of the electric blind plug of the present invention will be described in detail below with reference to the drawings. 1A and 1B are cross-sectional views of the electric blind plug of the present invention, and FIGS. 1C and 1D are cross-sectional views of the main part of FIG. 1A. 2 (A), (B), and (C) show the handling state of the electric blind plug of the present invention. 3A and 3B illustrate another application example of the electric blind plug of the present invention. First, in FIG. 1 (A), the insertion plates 2 and 3 made of an electrically insulating material are integrally inserted and fixed to the electrically blind plug body 1 made of an electrically insulating material. The pressing shaft 4 is inserted in parallel with the insertion plates 2 and 3, and the pressing shaft 4 slides in the axial direction in the plug body 1, and the upper part of the pressing shaft 4 is A pressing button 5 is provided, and a flange 6 is provided at the other end of the pressing shaft 4 so that the pressing shaft 4 does not come off from the plug body 1, and the upper portion of the plug body 1 has a convex portion. There is a hook-shaped engaging portion 7, and a soft electric insulating material 8 is attached to the lower surface of the plug body 1 from which the insertion plates 2 and 3 project. FIG. 1 (B) is a view showing a state in which the push button 5 is pushed and the push shaft 4 is lowered, and FIGS. 1 (C) and 1 (D) show main longitudinal cross-sectional views of the respective electric blind plugs. It was Next, the handling of the electric blind plug of the present invention will be described in detail with reference to FIG. FIG. 2 (A) shows an electric tap usually used at home, etc., (B) shows a state in which the electric blind plug of the present invention is inserted into the electric tap, and (C) shows the book. The state in which the devised electric blind plug is removed from the electric tap is shown. In FIG. 2 (B), when the insertion plates 2 and 3 of the electric blind plug body 1 of the present invention are pushed into the insertion holes 11 of the electric tap 10 which are always open, the insertion of the electric tap 10 is changed. The blind hole 11 is closed by the electro-blind plug body 1, in this case a soft electrically insulating material 8 attached to the electro-blind plug body 1 seals between the electro-blind plug body 1 and the electrical tap 10 to prevent moisture, Prevent invasion of dust and insects. Next, when removing the electro-blind plug, as shown in FIG. 2 (C), the catch 7 of the electro-blind plug body 1 is clamped by the index finger and the middle finger, and the pressing button 5 is pushed down by the thumb. The pressing shaft 4 pushes down the surface of the electric tap 10 so that the electric blind plug can be easily detached with one hand from the electric tap. Next, another first application example of the electric blind plug of the present invention will be described. FIG. 3A shows an electric plug to which the technique of the present invention is applied, in which plug plates 22 and 23 made of an electrically conductive material are inserted and fixed to the plug body 20, and one of the plug plates 22 and 23 is inserted. Is the insertion side of the electric tap, and the other end is connected to the lead wire of the electric supply cord 29 by the fixing screw 28. The plug body 20 is provided with a pressing shaft 4 made of an electrically insulating material according to the present invention, a pressing button 5, a soft electrically insulating material 8 and a catching portion 7 of the body. Conventionally, when the electric plug having the above structure is detached from the electric tap, it is difficult to remove the electric plug by grasping it with a fingertip.Therefore, the electric plug may be used dangerously such as pulling the electric supply cord. However, in the electric plug of the present invention, the push button 5 can be easily pushed down with one hand to remove the electric plug. Furthermore, even when the electric plug is attached to the electric tap, the electric tap and the electric plug are sealed by the soft electric insulating material 8 so that moisture, insects and dust do not enter, and thus the safety is ensured. Is. Next, another second application example of the electric blind plug of the present invention in FIG. 3 (B) will be described. The electrically blind plug body 1 is integrally formed with insertion plates 32 and 33 of an electrically conductive material. One of the insertion plates 32 and 33 is an insertion side to the electric plug, and the other end is connected to the neon tube 30. However, the neon tube 30 is arranged in the hole 31 of the plug body 1, and the hole 31 is protected by the transparent lid 34. Of course, in this application example, the pressing shaft 4 made of an electrically insulating material is also pressed. It comprises a button 5, a soft electrically insulating material 8 and a catch 7 on the body. In this application example, when the electric blind plug body 1 is inserted into the electric tap, the opening hole of the electric tap is sealed to ensure safety and at the same time, the electric power is supplied to the electric tap. By turning on the neon tube 30, it is possible to make a visual check, to know the electrical continuity state of the domestic electric tap, and to play a role of urging the operator to handle electricity safely. As described above, the structure and handling of the electric blind plug of the present invention, and further application examples, the electric blind plug of the present invention has an extremely simple structure, is highly effective in terms of safety, and can be supplied in large quantities at low cost. It is possible.
