FIG. 3 is a vertical cross-sectional view along the longitudinal direction of a railway vehicle showing a connection region of a conventional structure. The vertical sectional view shown in FIG. 3 corresponds to the BB sectional view of FIG. A train car formed by composing a plurality of railway cars 1 has a driver's seat and a conductor's compartment at both ends of the train car.

In order to control various control devices, broadcasting devices, and the like mounted on the railway cars 1 that constitute the train set, from the driver's cab and the conductor's room, the train train is a train that transmits and receives control commands and the like over the entire length of the train train. A through line 63 is provided. The lead-through line 63 includes a control circuit line for commanding acceleration and deceleration of the train set, a brake circuit line for commanding brake control, a door closing circuit line for controlling the opening and closing of the side sliding door 24 (see FIG. 1), a broadcasting circuit line, air conditioner control circuit lines, and so on.

The lead-through wire 63 is installed in an electric wire gutter (not shown) provided below the underframe 10 that forms the floor of the railroad vehicle 1, or is laid in the hollow part of the hollow extruded shape member that constitutes the underframe 10. may be Here, the lead-through wire 63 laid in the hollow portion of the hollow extruded shape forming the underframe 10 will be described as an example. The lead-through line 63 laid in the hollow portion of the hollow extruded shape is sometimes called an in-floor transmission line (63).

A description will be given of how the underfloor transmission line (63) is pulled through from one end of the train set to the other end. The railway vehicle 1 is provided with a wire transfer box 53 and a single-plug connection box 55 below both ends of the underframe 10 in the X direction. The in-floor transmission line (63) laid in the hollow portion of the underframe 10 of the railroad vehicle 1 reaches the end of the underframe 10 in the X direction, and passes through the wire transfer box 53 to the hollow portion of the underframe 10. A lead-through wire 63 led downward from the underframe 10 is connected to a terminal block (connection area D) inside the single plug connection box 55 .

A lead-through line 63 that straddles adjacent railcars 1 is connected to a connector receiver 58 of a single plug connection box 55 provided at the other end in the X direction of one railcar 1 and one end of the other railcar 1 in the X direction. are connected by a jumper wire 65 connecting the connector receptacle 58 of the single-plug connection box 55 provided at the end of the train, and the entire train car is drawn through.

On the other hand, a door closing circuit line, a broadcasting circuit line, an air conditioner control circuit line, etc. (floor transmission line 61) laid at a high position in the interior of the railroad car 1 in the Z direction is connected from the end of the roof structure 40 in the X direction. It hangs down in the -Z direction and connects to the terminal block inside the low-voltage connection box 51 provided between the end structure 30 and the end end material 31 (connection area A). The under-floor transmission line 62 is laid from the terminal block (connection area B) inside the low-voltage connection box 51 to the X-direction end of the underframe 10 to the inside of the hollow portion (installation area E). It is guided from the hollow portion of the underframe 10 to the lower side of the underframe 10 through the passage, and is connected to the terminal block (connection area C) inside the single-plug connection box 55 .

In the connection areas A to D, the connection work for connecting the floor transmission line 61 and the in-floor transmission lines 62 and 63 to the terminal block inside the low-voltage connection box 51 or the single plug connection box 55 mainly consists of the following work steps. .
(a) Remove the coating from the end of the electric wire (b) Attach a crimp terminal to the stripped bare wire (c) Crimp the crimp terminal attached to the bare wire (d) Crimp the crimped terminal is fixed to the terminal block. Since the above-described steps are performed in a narrow space at the end of the railway vehicle 1 in the X direction, a plurality of workers cannot engage in the above-described work steps almost simultaneously, resulting in a large manufacturing man-hour. There was another issue.

FIG. 4 is a vertical cross-sectional view along the longitudinal direction of the railroad vehicle, showing how the low-voltage connection box provided in a manner penetrating through the underframe is installed. A conventional low-voltage connection box 51 (Fig. 3) and a single-plug connection box 55 (Fig. 3) are replaced with a low-voltage connection box 56 with a single plug that integrates the functions of both, and the lower end of the low-voltage connection box 56 with a single plug is provided in the underframe 10 of the railroad vehicle 1 in a manner that passes through a through hole (not shown) provided in the underframe 10 .

A connector 57a to which floor transmission lines 61 such as a door closing circuit line, a broadcasting circuit line, an air conditioner control circuit line, etc. A mating connector receptacle 58a is provided. A lead-through line (underfloor transmission line ) 63 to which the connector 57b is connected, and a connector receiver 58c to which the connector 57c to which the jumper wire 65 is connected is connected.

The connecting portion between the connector 57a and the connector receptacle 58a corresponding to the connection area A in FIG. 3 and the connecting portion between the connector 57b and the connector receptacle 58b corresponding to the connection area D in FIG. It may be connected to a wiring having a crimp terminal on the side. That is, any method can be adopted for connection.

By adopting the low-voltage connection box 56 with a single plug, a crimp terminal is provided at one end of the under-floor transmission line 62 shown in FIG. , the work of laying the under-floor transmission line 62 in the hollow part of the underframe 10 (laying area E), and the other end of the under-floor transmission line 62 having a crimp terminal attached to the terminal block of the single plug connection box 55. Since the wire connection work (work area C) can be omitted, the efficiency of the wire connection work can be improved and the manufacturing man-hours can be reduced.

Manufacturing man-hours are required to pass the low-voltage connection box 56 with a single plug through the underframe 10 and process the through holes. The man-hour reduction effect due to the manufacturing man-hours greatly exceeds the man-hours for manufacturing through-holes.

Therefore, according to the present invention, it is possible to provide a rail vehicle capable of increasing the efficiency of the work of connecting electric wires such as control command lines, information transmission lines, and low-voltage wiring, and reducing manufacturing man-hours.
