す。 Since the contact piece 11 attached to the insulating piece main body 6 is pressed into contact with the conductor 1 in this manner, it can also serve as a terminal for a conventional signal line, and the number of parts is reduced. Therefore, the cost is low. In addition, since the contact piece 11 is brought into pressure contact with the conductor 1, there is no need to form a hole for a terminal in the conductor 1, and the processing of the insulated trolley wire 3 is easy.
Improves workability. Note that since the contact piece 11 contacts the non-contact surface of the conductor 1, the current collector cannot pass through. Furthermore, since the signal line 10 is connected within the insulating piece main body 6, wiring from the control panel is easy, and specification changes such as canceling the insulation section can be made in one place.

過を防げない。 The structure for fixing the insulating piece main body 6 to the insulated trolley wire 3 is not limited to this embodiment.
Although it may be a screw-fixed type as in the illustrated example, this embodiment provides the following advantages. That is, the insulating piece main body 6 covers the insulated trolley wire 3 from above, and the insertion engagement piece 7 and the side edge engagement piece 8 engage from below, so that it is securely fixed. In this case, since the elasticity of the insulating piece 5 and the insulated trolley wire 3 is used for fixing, unlike fixing with screws, it will not come off due to vibration etc. and is highly reliable. Moreover, since it has a hooking structure using the insertion engagement piece 7 and the side edge engagement piece 8, it can be attached extremely easily, unlike the conventional method using screws. When removing it, it can be easily removed by inserting a minus dry drive or the like inside the side edge engaging piece 7 and rotating it in the direction opposite to the direction of arrow Q in FIG. 3A. In addition, in the state where this insulating piece is attached, the insertion engagement piece 7 and the side edge engagement piece 8 are located outside the partition wall 9 of the insulated trolley wire 3, and cannot prevent the current collector from passing through.

い。 In the above embodiment, only one contact piece 11 is provided, but two contact pieces 11 may be provided, each contacting the conductor 1 on both sides of the notch 4 for forming an insulating section. Further, the press-contact location of the contact piece 11 is not limited to the upper surface of the conductor 1, but may be any current collector non-contact surface of the conductor 1. Further, the direction in which the signal line 10 is drawn out is not limited to the upper side of the insulating piece main body 6, but may be in the front and back or left and right directions.
