Description

[Detailed explanation of the invention] This invention is designed to prevent unnecessary movement of the east line connecting the frame and the middle body in a relay frame, etc., which is rotatably equipped with a relay, etc. installed inside the frame. This invention relates to an east line support device in which the east line is not supported.

-□As shown in Figure 1, the conventional relay rack has a rack body 1 fixed to the floor, etc., with a plurality of six relays or relay units installed inside the rack, and a single relay rack. It is rotatably mounted on a rotating shaft 3, and the bundle wire fixing position A on the frame 1 side and the east line fixing position B on the mid-term rest 2 side are connected by the bundle wire 4. When inspecting, it is necessary to rotate the vehicle by more than 90 degrees from the position of intermediate rest 2 shown by the solid line to the position shown by the dashed dotted line using the rotating shaft 3. At this time, the distance between both east line fixing positions A and B is long. Therefore, the length of the wire bundle 4 must be made long.

Therefore, when the middle rest 2 is returned to the position shown by the solid line in the figure, the distance between the two wire bundle fixing positions A and B becomes shorter, and the wire bundle 4 is less likely to bend and be stored in a predetermined storage position.

In particular, if there are a large number of wires in the wire bundle 4 and the wires are thick, the wire bundle 4 may be bent, caught on a protrusion on the frame 1, or caught between the frame 1 and the middle rest 2. However, accidents such as wire breakage may occur.

With the above points in mind, this idea eliminated all accidents on the East Line due to rotation during mid-day breaks.Next, we will explain this idea in detail along with Figures 2 and 3, which show examples of its implementation. Explain.

In FIGS. 2 and 3, 1, 2, 3. A and B are the same as those shown in Fig. 1, but the east line support device is different.

That is, the bundled wire 5 connecting the bundled wire fixing position A on the frame 1 side and the east line fixing position B on the intermediate break 2 side is routed to both rotating fixed positions A and B via the outside of the rotating shaft 3. □, and both east line fixed positions A and B are provided at almost the same height.

Therefore, when the middle rest 2 rotates in the direction of the arrow shown from the position indicated by the solid line in the figure to the position indicated by the dashed dotted line in the figure, the bundled wire 5 only loosens slightly at the same height, and the movement of the bundled wire 5 is wasted. This prevents the wire bundle 5 from getting caught on a protrusion, and prevents the wire bundle 5 from being caught between the frame 1 and the middle rest 2.

Note that the position where the wire bundle 5 is led out from the frame 1 is not necessarily limited to the east line fixing position A, but is set to the position A', and the position where the wire bundle 5 is introduced into the middle rest 2 is B'. The respective derivation and introduction positions may be A'.

It is sufficient to pass through the respective fixed positions A and B from B'.

Furthermore, the two fixed rotation positions A and B do not necessarily have to be at the same height; in the case of Fig. 3, the fixed position A of the frame 1 is set slightly higher than the fixed position B of the intermediate rest 2. You can.

Furthermore, the bundle wires 5 are not limited to the ceiling side of the middle rest 2, but may be provided on the bottom side, and the bundle wires 5 are located on the top plate of the middle rest 2 or the bottom plate of the frame 1, and the bundle wires 5 It is stable without sagging.

Furthermore, if it is necessary to rotate the middle rest 2 by a large angle such as 180 degrees, the bundle line 5 may be separated from the rotation axis 3 for a long time during rotation, resulting in an unstable condition. It may be locked by a ring or other guide near that point.

Note that 6 in FIG. 3 indicates a relay or a relay unit.

As described above, according to the east line support device such as the relay rack of this invention, the middle suspension is rotatably attached to the frame by one rotating shaft, and the east line is rotated by connecting the frame and the middle suspension. By wiring the wires through the vicinity of the shaft and making the east line fixing position of the frame and the middle rest almost at the same height, the east line is located at the same height when the middle rest rotates, and it is not a fraction of the east line. Because there is no movement, it is possible to prevent accidents where the East Line gets caught or breaks.
