[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.

[Prior art]

FIGS. 1 and 2 show a conventional high voltage circuit intervehicle transfer device. In the figure, an insulating support 2 is provided on the top surface of the roof of a connected vehicle 1 with the connecting surface sandwiched therebetween, and the center portion of a conductor 3 having a connector 4 is connected to a rod-shaped member attached to the top of the insulating support 2. It is supported at the center of 5. Rod-shaped body 5
is attached to the upper part of the insulating support 2 via an inner spherical bearing ring 6 and an outer spherical bearing ring 7. However,
In order to constantly maintain the support point of the conducting wire 3 near the center between the vehicles 1, a spring 8 is provided between the end of the rod-shaped body 5 and the spherical bearing inner ring 6.
The balance of the reaction force is used. In such a configuration, if the spherical bearing outer ring 7, the spherical bearing inner ring 6, and the rod-shaped body 5 are allowed to slide with low friction, the rod-shaped body 5 can slide against the spherical bearing outer ring 7. Rotational motion on a conical surface with the spherical center as the apex and reciprocating motion in the direction of the central axis of the spherical surface are possible.

The vehicle inter-vehicle transfer device 9 is used by being attached to the end room root of the vehicle 1 as shown in FIG.
Relative displacements occur between the vehicles 1 in the front-rear, left-right, and up-down directions due to vibrations such as pitching, rolling, and yawing that occur as the vehicles travel, and displacements that occur as the vehicles pass through curved roads. The above-mentioned vehicle inter-vehicle transfer device 9 is
Although this structure is suitable for the vehicle 1, it is often necessary to disconnect the vehicles 1 from each other for reasons of vehicle operation. In this case, since the vehicles 1 are connected to each other by the rod-shaped body 5 and the conductive wire 3, the inter-vehicle transfer device 9 must be removed from the insulating support 2 in order to disconnect the connection. Therefore, in the case of such a configuration, there is a drawback that it is troublesome to remove the entire inter-vehicle transfer device 9 every time the connection is released.

As an example of a structure that solves this problem, as shown in FIG. A convex portion 14 is provided, a connection plate 13 and a recess 15 are provided on the end face of the other rod-shaped body 11, and the convex portion 14 is fitted into the recess 15, and each connection plate 13 is connected to the connector 4 fixed to the end of the conducting wire 3. Fixing bracket 1
There is a configuration in which they are connected by being fixed by 2. In such a configuration, when the vehicle is to be uncoupled, the fixing fitting 12 is removed and the rod-shaped body 10,
It can be easily divided by dividing 11 and the conducting wire 3. In addition, when connecting the devices, align each connection plate 13 and connector 4 and attach the fixing metal fittings 12.
Just stick it in place. However, even with such a configuration, it is necessary to climb onto the roof of the vehicle 1 to perform the work in order to disconnect the vehicles, which is still troublesome.

[Purpose of invention]

The purpose of this invention is to have a simple configuration,
Another object of the present invention is to provide a high-voltage circuit inter-vehicle transfer device that can be automatically connected and disconnected without special operations.

[Summary of the idea]

The present invention consists of insulating supports disposed on the roofs of vehicles to be connected facing each other across a connecting surface, a bearing that allows the insulating supports to move in the axial direction, and a rotation in a conical surface. rod-shaped bodies each supported via spherical bearings that allow movement, a spring that projects toward the vehicle connecting the rod-shaped bodies, and a conical convex tip provided at one tip of each of the rod-shaped bodies. a connecting body forming a conical concave portion provided at the other end of the rod-shaped body and having its own tip fitting with a conical convex portion of the connecting body; and a connecting body of the convex portion. a convex member formed at the distal end of the rod-like body protruding from the tip; a contact piece installed at the distal end of the rod-like body inside the connecting body of the recess and fitting with the convex member; It has a rod-shaped support surface consisting of a curved surface with a concave central part,
The lowest position of the support surface is at a position where the contact point of each of the connecting bodies is shifted away from the center of the connecting body from the line connecting the centers of rotation in the conical plane of each of the rod-like bodies. The device is characterized by comprising a support member having a height to support the body.

[Example of idea]

An embodiment of the present invention is shown below in Figures 5 to 10.
This will be explained using figures. FIG. 5 shows an overall view of the inter-vehicle transfer device 16 according to the present invention, and FIG. 6 shows details of the rod-shaped body support part, and the same reference numerals as in the conventional example indicate the same members. 17 and 18 are connecting bodies, and 19 is an annular spacer through which the rod-shaped bodies 10 and 11 are slidably inserted. 20 is a protrusion fixed to the rod-shaped body 10; 21, 22, 23 are springs;
and 22 have the same spring constant, and spring 23 has the same spring constant as spring 2.
It has a sufficiently soft spring constant compared to 1 and 22. 24 has a gap that prevents the spacer 19 from coming into contact with the relative displacement between the moving vehicles 1, and when the connection is released, the rod-like bodies 10 and 11 are divided at the center and the center of rotation of the spherical bearing is This is a protrusion that prevents further rotation when the spacer 19 rotates downward as a center and is lowered. That is, the protrusion 24 is disposed below the joint side of the rod-shaped bodies 10 and 11, and has a rod-shaped body support surface consisting of a curved surface with a concave central portion, and the lowest position of the support surface is connected to each of the connecting bodies 17. . In the shifted position, each rod-shaped body 10,
The support member has a height that supports 11. In detail, in the vertical direction, the connector 1
The rod-like bodies 10 and 11 are supported in a non-coupled state so that the contact points of the rod-like bodies 7 and 18 are above a line connecting the rotation centers of the rod-like bodies 10 and 11 in the conical plane. moreover,
In the horizontal direction, an arcuate end surface 33 formed on the protrusion 24, which will be described later, positions the contact point of the connecting bodies 17 and 18 on both sides in the left-right direction from a line connecting the rotation centers in the conical plane. The rod-shaped bodies 10 and 11 are supported. 25 is the spring 21, 2 when the connection is released.
This is a stopper when the rod-shaped bodies 10, 11 slide toward the connecting surface due to the restoring and elongation of the rod-shaped bodies 10, 1.
It is removably fixed to 1. Conductive wires 3 connect rod-like bodies 10 and 11 to the top of insulating support 2 via connectors 4, respectively. Figure 6 shows rod-shaped body 1
Although the side of rod-shaped body 10 is shown, the side of rod-shaped body 10 is similarly configured.

In the inter-vehicle transfer device 16 configured as described above, the relationship between the rod-shaped bodies 10, 11, the spherical bearing inner ring 6, and the spherical bearing outer ring 7 is the same as in the conventional example, so that the relative relationship between the vehicles 1 is The operation for displacement is exactly the same. Since the rod-like bodies 10 and 11 are fitted together at the connecting bodies 17 and 18, it is necessary to allow for relative displacement between the vehicles 1. The problem is that when the mutual distance between the insulating supports 2 increases, the length of the rods 10 and 11 must be made sufficient for the maximum distance, and the mutual distance must be increased until the spherical bearing inner ring 6 hits the stopper 25. The condition is that the springs 21, 22 are still in a compressed state when expanded and are configured to generate the compressive force necessary for the mating of the coupling bodies 17, 18. In addition, since the spring constants of the springs 21 and 22 are the same, their reaction forces are balanced, and the connecting body 1
7 and 18 will always be kept centered between the vehicles 1.

Next, the connecting bodies 17 and 18 will be explained. 7th
The figure shows details of the connecting bodies 17 and 18, and FIG. 8 shows a cross section taken along the line AA in FIG. 7. 26 is a convex portion fixed to the end of the rod-like body 10; 27 is a contact piece rotatably provided at the end of the rod-like body 11 to form a recess; 28 is a ring-shaped spring; It is configured so that a tightening force is generated from the surroundings. 29 is a projection fixed to the rod-shaped body 10; 30 is a guide surface provided inside the connecting body 18; the connecting body 18 is slidably attached to the rod-shaped body 10; It slides to the state shown in the figure, and the sliding stops when the bottom surface of the guide surface 30 and the protrusion 29 come into contact. 31 is a conical convex surface at the end of the connecting body 18, and 32 is a conical concave surface provided at the end of the connecting body 17. The conical convex surface 31 and the conical concave surface 32 have the same cone angle.

Since the parts of the connecting bodies 17 and 18 are constructed as described above, the high voltage current flows through the rod-shaped body 10, the convex part 26,
Electricity is applied through the path of the contact piece 27 and the rod-shaped body 11, and by appropriately selecting the tightening force of the spring 28, the convex portion 2
6 and the contact piece 27, and between the contact piece 27 and the rod-shaped body 11, a stable energization state can be obtained.

Next, the operation of the inter-vehicle transfer device 16 when the vehicles 1 are connected to each other will be explained with reference to FIGS. 9 and 10. FIG. 9 is a cross-sectional view taken along the line BB in FIG. 6, showing the fitted state of the rod-shaped body 11 and the spacer 19.
33 is an arcuate end face provided on the protrusion 24;
As mentioned above, the gap between the spacer 3 and the spacer 19 is configured so that the relative displacement between the moving vehicles 1 does not cause the space between them to overlap, but when the inter-vehicle transfer device 16 is uncoupled, the rod-shaped body 10 and 11 rotate and the spacer 19
descends and hits the end face 33, preventing further rotation. In this case, if the arc of the end face 33 is constructed so that the point on the line passing through the center of the protrusion 24, that is, the center of each insulating support 2 fixed to each vehicle 1, coincides with the lowest point of the arc, The seat 19 stops coincident with its lowest point.

Since the vehicles 1 are usually connected on a straight road, the rod-like bodies 10 and 11 are located on a straight line passing through the center of the insulating support 2. In that case, the connecting body 1 immediately before connecting the vehicles 1 to each other
The state of the rods 7 and 18 is shown in FIG. 10, and the process by which the rod-shaped bodies 10 and 11 reach the fitted state will be described below with reference to FIG. The rod-like bodies 10, 11 form an angle as shown in the figure, and the springs 21, 22, 23 are in an extended state,
When vehicle 1 approaches, first connect body 1 as shown in the figure.
The upper ends of 7 and 18 touch each other. When the vehicle 1 approaches further from this state, the springs 21, 22, 23 installed between the spherical bearing inner rings 6 and the connecting bodies 17, 18 are compressed, and their relative dimensions are shortened. At this time, the contact point of the connecting bodies 17 and 18 is further than the line connecting the rotation centers of the respective spherical bearings.
7, 18, the reaction force of the springs 21, 22, 23 generates a force in the direction in which the connecting bodies 17, 18 are joined, and the spherical bearing inner ring 6 The equiacute angle of the isosceles triangle formed by each other and the connecting bodies 17, 18 gradually decreases. When the vehicle 1 further approaches, the tip of the convex portion 26 hits the conical concave surface 32, and the tip is guided by the conical concave portion 32 to the center thereof. Through the above operations, the rod-like bodies 10 and 11 become in a straight line, and as the vehicle 1 approaches, the convex portion 26 is fitted into the center of the annularly arranged contact piece 27, hits the end of the rod-like body 11, and stops. Complete the bond. In this state, the conical concave surface 32 and the conical convex surface 31 are in contact and fit, and are pressed against each other by the reaction force of the springs 21 and 22, so that the connecting bodies 17 and 18 are not displaced from each other and are integrated into the vehicle. The contact piece 27 and the rod-shaped body 10 will not come off even if the contact piece 27 and the rod-shaped body 10
This ensures that a good fit is maintained.

[Effect of idea]

As explained above, according to the present invention, when connecting vehicles, it is possible to fit the rod-shaped bodies by simply bringing the vehicles closer together, and when uncoupling, it is sufficient to simply move the vehicles away from each other. In addition to being able to connect and release automatically, the configuration can be simplified without providing any special control mechanism. Further, during connection, the fitted state of the rod-like bodies is maintained even in the face of relative displacement between the vehicles, so there is an effect that a stable energized state can be obtained.
