Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to electrical equipment that is housed in a housing and installed under the floor of a vehicle, and particularly relates to an underfloor device that is suitable for being installed and used in an electric railway vehicle. Regarding equipment.

[Background of the invention]

In electric railway vehicles, some of the electrical equipment is housed in equipment boxes (casings) as underground equipment.

With the exception of some body-mounted vehicles (vehicles in which the underfloor area is covered with skirts on the sides), such underfloor equipment is generally installed under the floor in an exposed state. Therefore, the outer box (equipment box) of such underfloor equipment needs to have a waterproof structure, so the ceiling panel, bottom panel, left and right side panels are fixed, and only the front and rear panels can be opened and removed. Conventionally, a type of inspection cover has been used.

At this time, there are two methods for installing the inspection cover: a hanging method and a screw tightening method. However, although this screw tightening method requires less space, it is inconvenient to handle.
The Kikagegane method is more commonly used in Nozozai because it can be made waterproof with a single touch.

An example of such underfloor equipment is shown in Figures 4 and 5.

In Towara 14 figure and Mashira 5 figure, 1 is the outer box (casing), 2
is a tray that stores electrical equipment, 3 is a connector for the tray, 4 is a receptacle for external connection, 5 is a cleat for fixing electric wires, 6 is a panel that accommodates the tray, 7 is wiring, and 8 is an inspection cover , 10 is a window for inserting a tray.

By the way, in recent years, there have been extremely strict demands for downsizing of under-floor equipment in vehicles, and for this reason,
Its external dimensions had to be reduced to the limit,
Therefore, it is almost impossible to leave extra space inside.

Against this background, conventional underfloor equipment does not require a dedicated space for wiring work, but instead requires wiring work in very narrow areas such as the hidden window of the tray or between equipment. For example, as shown in Figure 4 and Figure 5, the wiring 7 is installed along the cleat 5, which is installed in an extremely narrow space excluding the ψ mounting part of the tray 2, etc. Because of this, it was necessary to insert the fingers into the interior and grope around, which resulted in sufficient workability.

It has the disadvantage that it is difficult to obtain wires, and furthermore, the occurrence of tone wires cannot be sufficiently suppressed.

In addition, as for things related to this kind of thing.

For example, Japanese Utility Model Application Publication No. 59-117188 can be mentioned.

[Object of the Invention] The object of the present invention is to eliminate the drawbacks of the prior art described above, to obtain sufficient wiring workability without impairing the sealing function necessary for the outer box, and to easily improve quality. It is possible to provide underfloor equipment of the vehicle.

[Analysis of the invention, main points]

In order to achieve this object, the present invention provides an outer box for under-floor equipment with a structure in which the bottom plate is removable, and the electrical equipment to be housed in the box is placed on the bottom plate. 1. This allows wiring work to be done without the outer box.1
~． It is characterized by the fact that after the wiring work is completed, an outer box is placed over the device to make it an underfloor device.

[Embodiments of the Invention] Below, the underfloor equipment of a car door according to the present invention will be explained in detail with reference to illustrated embodiments.

Figures 1 to 3 show one embodiment of the present invention, and among these figures, Figure P11 shows the outer box part and the inner frame part attached to the bottom plate separately.

Figure 2 is the front view with the inspection cover removed, and Figure 3 is the 2nd
This is a cross-sectional view taken from line A-A in the figure, and in the figure of Kowara,
9 is a bottom plate made separately from the outer box 1, and 11 is an inner frame for attaching the tray 2 and its attached electrical equipment, which also serves as the panel 6 in Figure ν4 and Figure 5. Sen is the same as the conventional example shown in Figures 4 and 5.

Therefore, in this embodiment, it is clear from FIG.
As shown, the inner frame 11 is removed from the bottom plate 9, and the bottom plate 9
In this respect, in the conventional example shown in Figs. 4 and 5, the outer box 1 is integrated including the bottom plate, and the inner frame 11 is attached therein. It is very different from what is being said.

Therefore, according to this embodiment, first, the wiring 7 is installed with the bottom plate 9 removed from the outer box 1 as shown in FIG. ν1. At this time, when distributing wiring for each tray or electric device directly above the bottom plate 9, the inner frame 11 is removed from the bottom plate 9 in advance and the wiring work is performed. Then, when the installation of the arrangement s7 directly above the bottom plate 9 is completed, the inner frame 11 is attached to the bottom plate 9, and the arrangement @7 is placed on this inner frame 11. Incidentally, at this time, the wiring for the electrical equipment directly attached to the inner frame 11 is also completed.

After completing the installation of the connector 3 corresponding to each tray and all the wiring @ 7 for electrical equipment, this inner frame 11
Insert it into the outer box 1 as shown by the arrow in Figure 1, attach the bottom plate 9 to the outer box 1, and attach the external connection plug holder 4 connected to the wiring 7 to the outer box 1. The Japanese sentence is completed as shown in Fig. v3.

"Oh, you can easily add more plug holders 4 at this time by using a few inspection covers 8 on the back and front 1.

Therefore, according to this embodiment, most of the internal wiring work can be done with the outer box 1 removed, so the wiring work can be done while visually checking the work, and the necessary tools etc. There are almost no restrictions on its use, and accurate wiring can be performed with sufficient workability.

[Effect of the invention 1] As stated above, according to the present invention, most of the work required for internal wiring can be performed with the exterior removed. It is possible to easily obtain accurate wiring in a short time with 90% accuracy, and it is possible to reduce the extra space required just for wiring work, making it possible to achieve compactness, high quality, and low cost under the floor of the vehicle. Equipment can be easily provided.
