Further, 1 is an insulated electric wire after attachment, 11 is an insulating layer of the insulated electric wire, 12 is a conductor of the insulated electric wire, 2 is a holder having elasticity,
Reference numeral 21 is a guide portion provided at the tip of the holder 2, and 22 is a clip portion of the holder 2. Now, if the guide portion 21 is applied to the insulated electric wire 1'and the entire display portion 3 is pushed in the F direction in the drawing using an arbitrary insulating rod (not shown), the guide portion is caused by the reaction of the insulated electric wire 1 '.
21 is applied with a lateral force as shown in the figure, the holder 2 can open the guide portion 21 of the holder 2 to easily put the insulated wire in the position 1, and thereafter hold the insulated wire 1 by the elasticity of the clip portion 22. To do. In this way, it can be attached to the electric wire by simply pushing it with an insulating rod, so no power outage is required.

る。On the other hand, since the clip portion 22 is made of a conductive material, it has a capacitance Cs with the insulated conductor 12, and is connected to one electrode of the liquid crystal display element 33 by the lead wire 36.
The other electrode of the liquid crystal display element 33 is connected to a current collector plate 34 by a lead wire 35, and the current collector plate 34 has an electrostatic capacitance Co (not shown) with the ground. Therefore, the capacitance of the liquid crystal display element 33
If it is Cl, these capacitances are connected in series. The magnitude of each capacitance is generally Cl >> Cs >>
There is a relationship of Co. In this case, when the voltage V is applied to the conductor 12 of the insulated wire 1, Vl≈approximate to the liquid crystal display element 33.
A voltage Vl represented by (Vo / Cl) V is induced, and this voltage Vl
When the voltage exceeds the threshold voltage Vt of the liquid crystal display element 33, the liquid crystal display element 33 indicates that the device is in the power-on state. The display content can be seen through the window 32 of the display case 31.
保持具２は直接高電圧部に接するので、その端部に丸み
