Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an improvement in an inter-vehicle transfer device for high-voltage circuits insulated by air gaps among electrical circuits exchanged between connected vehicles. be.

[Background of the invention]

A conventional example of a high-voltage circuit inter-vehicle transfer device is disclosed in Japanese Utility Model Publication No. 13172/1983, the contents of which will be explained with reference to FIGS. 9 to 13.

In FIGS. 9 and 10, an insulating support 2 is provided on the roof surface of the connected vehicle 1 with the connection surfaces facing each other, and the center portion of the conductor 3 having the connector 4 is placed on the top of the insulating support 2. It is supported by a support metal 9 fixed to the center of the attached rod-shaped body 5. The rod-shaped body 5 is attached to the upper part of the insulating support 2 via a spherical bearing inner ring 6 and a spherical bearing outer ring 7. In order to always maintain the support point of the conductor 3 near the center between the vehicles, a spring 8 is provided between the end of the rod-shaped body 5 and the spherical bearing inner ring 6, and the reaction force of the spring 8 is balanced. We are using. Therefore, if the spherical bearing outer ring 7, the spherical bearing inner ring 6, and the rod-shaped body 5 are made to slide with low friction, the rod-shaped body 5 will be at the spherical center of the bearing with respect to the spherical bearing outer ring 7. Rotational motion on the conical surface with the apex at , and reciprocating motion in the direction of the central axis of the spherical surface are possible.

Such a vehicle inter-vehicle transfer device 10 is mounted on the end room root of the vehicle 1, as shown in FIG. Relative displacements occur among the vehicles 1 in the front-rear, left-right, and up-down directions due to oscillations such as pitching, rolling, and yawing that occur as the vehicle 1 travels, and displacements that occur as the vehicle passes through a curved road. Although the vehicle inter-vehicle transfer device 10 has a structure suitable for such vehicles 1, the conducting wire 3 performs a bending motion in accordance with relative displacement between the vehicles 1. However, the end of the conductor 3 is placed on the upper part of the insulating support 2, and the center part is placed on the rod-shaped body 5.
Since the lead wire 3 is fixed at the center of the lead wire 3, if the distance between each vehicle increases, it will be in the state shown in Fig. 12, and if it is reduced, it will be in the state shown in Fig. 13. This has the drawback that an unreasonable force is applied to the conductor 3, shortening the life of the conductor 3.

One possible solution to this problem is to lengthen the conducting wire 3 to make it easier to bend, but if the conducting wire 3 is made longer, the conducting wire 3 will sag, making it difficult to secure the gap size. Another method is to use a conductor 3 that is easy to bend, such as a braided conductor, but this method has the drawback of being expensive and having poor strength.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle inter-vehicle transfer device having a structure in which no unreasonable force is applied to the conductor wire due to the bending movement of the conductor wire due to relative displacement between the vehicles.

[Summary of the invention]

In order to prevent excessive force from acting on the bending movement of the conductor due to relative displacement between vehicles, it is necessary to have a structure in which the center part of the conductor is held in a state where it can freely rotate. In order to satisfy this requirement, the present invention provides a rotating member at the center of the rod-shaped body, and supports the center of the conducting wire with this rotating member.

According to the present invention, the central support portion of the conductor can freely rotate in response to the bending movement of the conductor due to relative displacement between vehicles, so that no unreasonable force is applied to the bent portion of the conductor. This has the effect of increasing the life of the conductor.
