【考案の詳細な説明】 本考案は電車線に関するものである。[Detailed explanation of the idea] This invention relates to overhead contact lines.

その固定には耐振動性の点から溶接を用いること
が望ましい。 As shown in Fig. 1, a conductive steel conductive steel cross-section T-shaped rigid wire 1', as shown in Fig. 1, is used as an overhead contact line.
It is known that two parallel electric wires 2' and 2' of twisted copper wire are mounted to reduce voltage drop.
In such overhead contact lines, it is necessary to fix the feeder wires to the rigid wire at regular intervals along the length.
It is desirable to use welding for fixing it from the viewpoint of vibration resistance.

点から溶接強度をそれほど大きくとれないから、
上記モーメントの発生は不利である。 By the way, as shown in Fig. 1, the feeder wires 2',
2′ are in close contact with each other, the feeder wire (copper)
Due to the difference in coefficient of thermal expansion between the feeder wire 2' and the rigid wire (steel), a thermal stress f is generated, which acts as a moment M at the joint P between each feeder wire 2' and the rigid wire 1'. However, the area of the T-shaped head of the rigid wire is small, and there is a limit to the amount of filler metal to be applied for welding, and from this point of view it is not possible to increase the welding strength.
The generation of said moments is disadvantageous.
本考案はかゝる不利を解消するために、上記き
電線を長手方向の一定間隔ごとに剛体線に溶接す

うにしたものである。 In order to eliminate such disadvantages, the present invention is designed to ensure that the feeder wires are securely isolated from each other when the feeder wires are welded to a rigid wire at regular intervals in the longitudinal direction.

とする構成である。 That is, the overhead contact line according to the present invention has two parallel electric wires placed on the T-shaped head of a rigid wire with a T-shaped cross section,
A pair of front and rear feeder wire isolation spacers are installed at regular intervals in the longitudinal direction of the parallel electric wire, filler metal is filled between these spacers, and the feeder wires are welded to the rigid body wire at regular intervals in the longitudinal direction. This is a configuration characterized by the following.

ている。 In Figure 2A and Figure 2B, 1 is the cross section T.
It is a type of rigid wire, made from conductive steel,
The current collector shoe of the train comes into contact with the lower rail surface 11. Reference numerals 2 and 2 denote two parallel feeder wires made of twisted copper wires, which are placed on the T-shaped head 12 of the rigid wire 1. A, ... are welding points, and two pairs of feeder wire isolation spacers (made of copper plate) shown in Fig. 3 are attached to the feeder wires 2, 2, front and rear, and there is a thermochemical reactivity between the spacers 3, 3. A filler material 4, for example a thermite agent, is filled. Therefore, feeder line 2,
2 and the rigid wire 1 are welded and fixed via a filler metal 4.

を剛体線に安定に固定できる。 As mentioned above, the overhead contact line according to the present invention is one in which two parallel electric wires placed on the T-shaped head of a T-shaped rigid wire are welded to the rigid wire at regular intervals in the longitudinal direction. Since the feeder line isolation spacer is installed at the welding point, the feeder wires can be reliably separated from each other, thereby preventing the generation of a moment due to thermal stress shown by M in Figure 1, and reducing the welding point. Despite the limitations on the amount of material used (large amounts cannot be used due to the narrow area of the T-shaped head of the rigid wire), the feeder wire can be stably fixed to the rigid wire.
