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 is particularly suitable for use when installed in an electric railway vehicle. Regarding underfloor equipment.

[Background of the invention]

In electric railway vehicles, some of the electrical equipment is housed in an equipment box (casing) K and placed under the floor.

However, 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 installed directly 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 board, bottom board, left and right side panels are fixed, and only the front and rear panels can be opened and closed. Conventionally, inspection covers that allow for additional rows have 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, so the latch method is more commonly used because it can be made waterproof with a single touch.

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

In these figures 4 and 5, 1 is the outer box (casing), 2
is a tray containing 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 an inner frame, 7 is wiring, 8 is an inspection cover,
10 is a window for inserting a tray.

By the way, in recent years, demands for downsizing the underfloor equipment of vehicles have become even stricter, and as a result, the external dimensions have been forced to be reduced to the absolute minimum.
Therefore, it is almost impossible to leave extra space inside.

Against this background, with conventional underfloor equipment, wiring work is required in extremely narrow areas such as the mounting window of the tray or between devices, rather than providing a dedicated space for wiring work. For example, as shown in the examples of FIGS. 4 and 5, the wiring 7 is arranged along the cleat 5, which is provided in an extremely narrow space excluding the mounted components such as the tray 2. For this reason, wiring work requires inserting one's hand into the interior and using a counterbore.This not only makes it difficult to obtain sufficient workability, but also makes it difficult to produce neatly and uniformly wired wires. The disadvantage is that it is difficult to eliminate the possibility of miswiring occurring. Incidentally, as related to this kind of thing, for example,
-117188 can be mentioned.

[Purpose of the invention]

The purpose of the present invention is to eliminate the drawbacks of the prior art described above, provide sufficient wiring workability to prevent the sealing function necessary for the outer box, and provide a structure for improving the quality of the underfloor of a vehicle. There is a need to provide equipment.

[Summary of the invention]

In order to achieve this object, the present invention configures a portion of the underfloor equipment to which a portion of the electrical wiring is attached as an independent distribution box, and allows the distribution box to be inserted into the interior from the side of the outer box and incorporated. It is characterized by a point K.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Below, the underfloor equipment for a vehicle according to the present invention will be described in detail with reference to illustrated embodiments.

Figures 1 to 3 show one embodiment of the present invention. In these figures, 9 is a distribution box, and the others are Figures 4 and 5.
This is the same as the conventional example explained in the figure.

The distribution box 9 is a hollow box with a thin thickness, and is made separately from the outer box 1. A predetermined number of cleats 5 are provided at predetermined positions inside the distribution box 9, and a cleat 5 is provided at one end. The external connection plug holder 4 is attached.

On the other hand, the rear panel of outer box 1 (right side in Figures 1 and 3)
An opening is formed in the box so that the distribution box 9 can be inserted from the direction of the arrow in FIG. 1, so that the distribution box 9 can be separated from the outer box 1 as shown in FIG. , or inserted and held directly under the ceiling board inside the outer box 1 as shown in FIG. 3.

Therefore, in this embodiment, first, as shown in FIG.
The distribution boxes 9 are placed in a state where they are extended in rows from the outer box 1 to the outside, and in this state, a part of the distribution wiring for the necessary connections between the external connection sockets 4 and each tray 2 and other electrical equipment, A part of the crossover wiring required for connection between the tray 2 and other electrical equipment is wired as a model, and fixed to the crease 15 in the distribution box 9 in a state where the east line is divided.

Next, after completing the installation of the necessary wiring, insert this distribution box 9 into the outer box 1 in the direction of the arrow in FIG. or other electrical equipment, and fix it to the cleat 5 to complete the wiring work.

Therefore, according to this embodiment, the wiring distribution part, which is the most troublesome part of the wiring work and is likely to cause incorrect wiring, and the 17111
Since the east line separation can be carried out with the distribution box 9 pulled out from the outer box 1 or outside, there is no need for manual work, and the work can be carried out reliably while checking visually. .

In this embodiment, since the external connection plug holder 4 is attached to the distribution box 9, the connection work to the plug holder 4 can also be performed externally, and the wiring work can be performed more easily.

〔Effect of the invention〕

As explained above, according to the present invention, the most difficult part of the work required for internal wiring can be performed while the work is removed from the outer box, thereby eliminating the drawbacks of the conventional technology. Easy to work with, accurate wiring can be easily obtained in a short time, and extra space required just for wiring work can be removed, resulting in a compact, high-quality, low-cost underfloor equipment for vehicles. can be easily provided.
