The lead-through line 63 laid in the hollow portion of the hollow extruded shape is sometimes called an in-floor transmission line (63).

床中伝送線(63)が、編成車両の一方の端部から他方の端部に引き通される様子を説明する。鉄道車両1は、台枠10のX方向の両端部の下方に、転線箱53と片栓ツナギ箱55とを備える。鉄道車両1の台枠10の中空部に敷設された床中伝送線(63)は、台枠10のX方向の端部に至ると、転線箱53を経由して台枠10の中空部から台枠10の下方に導かれた引き通し線63は、片栓ツナギ箱55の内部の端子台(結線領域D)に接続される。 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 .

隣り合う鉄道車両1に跨る引き通し線63は、一方の鉄道車両1のX方向の他方の端部に備えられる片栓ツナギ箱55のコネクタ受け58と、他方の鉄道車両1のX方向の一方の端部に備えられる片栓ツナギ箱55のコネクタ受け58と、を接続するジャンパ線65によって接続されて、編成車両全体を引き通される。 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.

一方、鉄道車両1の車内のZ方向の高い位置に敷設される戸閉回路線、放送回路線、空調装置制御回路線など(床上伝送線61)は、屋根構体40のX方向の端部から-Z方向に垂下して、妻構体30と妻内装材31との間に備えられる低圧ツナギ箱51の内部の端子台に接続する(結線領域A)。低圧ツナギ箱51の内部の端子台(結線領域B)から台枠10のX方向の端部から中空部の内部(布設領域E)に敷設される床中伝送線62は、転線箱53を経由して台枠10の中空部から台枠10の下方に導かれ、片栓ツナギ箱55の内部の端子台(結線領域C)に接続される。 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 .

結線領域A~Dにおいて、床上伝送線61、床中伝送線62、63を低圧ツナギ箱51または片栓ツナギ箱55の内部の端子台に結線する結線作業は、主に以下の作業ステップからなる。
(a) 電線の端部の被覆を取り除く
(b) 被覆を取り除いた裸線に、圧着端子を取り付ける
(c) 裸線に取り付けた圧着端子を圧着(かしめる)する
(d) 圧着した圧着端子を端子台に固定する
上述したステップは、鉄道車両1のX方向の端部の狭い空間での作業となるため、複数の作業者がほぼ同時に上述した作業ステップに従事できず、製造工数が大きくなる課題があった。
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.

図4は、台枠を貫通する態様で備える低圧ツナギ箱の設置状況を示す鉄道車両の長手方向に沿う垂直断面図である。従来の低圧ツナギ箱51(図3)と片栓ツナギ箱55(図3)とを両者の機能を集約した片栓付低圧ツナギ箱56に代替するとともに、片栓付低圧ツナギ箱56の下端部が台枠10に設けた貫通穴(図示なし)を貫通する態様で鉄道車両1の台枠10に備えたものである。 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 .

片栓付低圧ツナギ箱56の台枠10から上部(+Z方向)に突出する部位には、戸閉回路線、放送回路線、空調装置制御回路線などの床上伝送線61が接続したコネクタ57aと結合するコネクタ受け58aが備えられる。片栓付低圧ツナギ箱56の台枠10から下部(-Z方向)に突出する部位には、転線箱53を経由して台枠10の下方に導かれた引き通し線(床中伝送線)63が接続するコネクタ57bが結合するコネクタ受け58bと、ジャンパ線65が接続されたコネクタ57cが結合するコネクタ受け58cと、が備えられる。 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.

図3の結線領域Aに相当するコネクタ57aとコネクタ受け58aとの結合部と、図3の結線領域Dに相当するコネクタ57bとコネクタ受け58bとの結合部と、はコネクタ結合ではなく、端子台に圧着端子を有する配線に結線する態様であってもよい。すなわち、結線については、任意の方式を採用することができる。 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.

片栓付低圧ツナギ箱56を採用することによって、図3に示した床中伝送線62の一方の端部に圧着端子を備えて低圧ツナギ箱51の端子台に結線する作業(作業領域B)と、床中伝送線62を台枠10の中空部に敷設する作業(布設領域E)と、床中伝送線62の他方の端部に圧着端子を備えて片栓ツナギ箱55の端子台に結線する作業(作業領域C)の作業を省略することができるので、結線作業の効率を高めて製造工数を小さくできる。 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.

片栓付低圧ツナギ箱56を台枠10に貫通させ貫通穴を加工する製作工数が生じるが、作業領域Bおよび作業領域Cでの結線作業に係わる製作工数と、布設領域Eでの布設に係わる製作工数とによる工数削減効果が貫通穴を加工する製作工数を大幅に上回る。 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.

このため、本発明によれば、制御指令線、情報送信線および低電圧配線等の電線の結線作業の効率を高め製造工数を小さくできる軌条車両を提供することができる。 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.
