Description

Technical Field

[0001] The present invention relates to a railway vehicle connector, and more particularly to a railway vehicle connector that can achieve mechanical connection when connecting adjacent railway vehicles, and can quickly and easily connect railway vehicles by connecting air piping and electric wire connection terminals at one time without having to perform air piping and electrical connection separately. Background Art

[0002] Railway vehicles are operated by connecting multiple carriages or freight vehicles to the rear end of a leading vehicle that generates propulsion power. To connect the vehicles, a Figure 1 and Figure 2 Close-fit connector shown.

[0003] Among them, a ring-shaped vehicle body connection part 11 is formed at one end of the close-fit connector body 10. The above-mentioned vehicle body connection part 11 is used to insert and fix the connecting part. The above-mentioned connecting part is in the shape of a rod and is fixedly arranged on the vehicle. A fastener 12 and a fastener insertion groove 13 are formed at the other end. The above-mentioned fastener 12 and the fastener insertion groove 13 have facing cross-sections at adjacent positions. Therefore, when a pair of connectors connected to the vehicle through the vehicle body connection part 11 are combined to connect the vehicle, the fasteners 12 of the connector on one side are respectively inserted into the fastener insertion groove 13 of the connector on the other side.

[0004] Furthermore, an arc-shaped locking groove 12c is formed on the inner side of the fastener 12. Since the locking member 21 is rotatably disposed inside the locking groove 12c, Figure 2 As shown, the locking groove ends of the fastener inserted into the fastener insertion groove 13 are respectively locked by the upper locking parts to prevent disengagement, thereby connecting the vehicles on both sides. Since the fastener 12 includes: a support portion 12a, which is installed on the inner wall of the fastener insertion groove 13; and an insertion guide portion 12b, which is formed as a whole in a roughly quadrangular pyramid shape in front of the support portion, when the fastener 12 is inserted, the locking component 21 elastically supported by the spring 23 is gradually rotated and inserted through the insertion guide portion 12b. After the insertion is completed, the locking component 21 is restored to its original position due to the elastic force of the spring 23 and is placed inside the locking groove 12c, thereby firmly connecting the vehicles on both sides.

[0005] In this case, when the vehicle is to be separated, Figure 2 The unlocking lever 22 is rotated in the direction of the arrow to disengage the locking portion 21a of the locking member 21 from the locking groove 12c, thereby releasing the coupled state.

[0006] However, the above-mentioned existing railway vehicle connectors are only used for mechanical connection. Since it is impossible to connect the air piping used to control the electrical connection or the air pressure brake device, when the operation of the railway vehicle is interrupted due to engine failure, when the rescue train tows the faulty train by connecting to the faulty train, the faulty train needs to be directly connected to the rescue train for broadcasting or lighting circuits and other required control circuits.

[0007] Therefore, since the air piping or electrical connection work becomes cumbersome and time-consuming, not only can the train not be able to run again quickly, but even when separated, the complicated steps described above need to be repeated, which will cause a lot of inconvenience to passengers when the faulty train is a carriage.

Figure 7 The figure is a cross-sectional view of a second connector of a railway vehicle connector according to another embodiment of the present invention.

[0030] like Figure 3 and Figure 4 As shown, the present invention relates to a connector for railway vehicles, and its structure includes: a first setting part 100, which is set on a chassis, and the above chassis is formed at the lower part of the body of the railway vehicle; and a first connector 200, which is set on the above first setting part 100, and the above first connector 200 is used to mechanically connect the front and rear vehicles.

[0031] A second installation portion 300 is formed at the lower portion of the first installation portion 100 , and a second connector 400 is provided at the second installation portion 300 . The second connector 400 is used to connect air pipes and wire connection terminals of front and rear vehicles.

[0032] Therefore, when connecting the front and rear vehicles, the present invention mechanically connects the front and rear vehicles through the above-mentioned first connector 200, and at the same time, connects the air piping and makes an electrical connection through the above-mentioned second connector 400. Since there is no need for the management personnel to separately connect the air piping or make an electrical connection, the front and rear vehicles can be connected quickly and easily.

[0033] On the other hand, since the first connector 200 is a well-known technology, a separate description thereof will be omitted.

[0034] Furthermore, the second connector 400 includes a connecting portion 410 for connecting front and rear vehicles, a connecting rod 420 formed at the rear of the connecting portion 410 , and an extending rod 430 formed at an end of the connecting rod 420 .

[0035] The extension rod 430 is inserted and connected to the second setting portion 300 . The second setting portion 300 is formed at the lower portion of the first setting portion 100 . A first buffer component 440 is disposed between the extension rod 430 and the second setting portion 300 .

[0036] In this case, the first buffer component 440 is made of an elastic material, such as rubber or synthetic rubber, and thus is helpful to reduce the impact generated when the vehicle is connected.

[0037] On the other hand, the above-mentioned connecting part 410 includes: a connecting body 411, formed at the front end of the above-mentioned connecting rod 420; a connecting guide 412, formed to protrude forward on the front side of the above-mentioned connecting body 411; and a connecting hole 413, used to allow the connecting guide 412 of the other side connector to be inserted into the side of the above-mentioned connecting guide 412.

[0038] Among them, the above-mentioned connecting guide 412 is in a cone shape. When the above-mentioned connecting guide 412 is inserted into the connecting hole 413 in order to connect the second connector 400, even if the positions of a pair of second connectors 400 are partially misaligned, the misaligned part will be corrected by the inclined surface of the cone shape of the connecting guide 412, so that it can be easily combined.

[0039] In this case, the wire terminal setting portion 415 is formed in a front-to-rear through-going manner at the upper portion of the above-mentioned connection body 411, and the air piping setting portion 414 is formed in a front-to-rear through-going manner at the lower portion of the connection body 411. The wire terminal setting portion 415 is provided with a wire connection terminal (not shown) for transmitting electric power and electric signals of each vehicle, and the air piping setting portion 414 is provided with an air piping connection portion (not shown) for connecting the air piping (not shown) of each vehicle.

[0040] Therefore, when the second connector 400 is combined, the wire connection terminals and the air pipe connection parts provided in the wire terminal setting part 415 and the air pipe setting part 414 are automatically connected. Therefore, when the management personnel does not separately perform the connection and electrical connection of the air pipe, the connection can be easily made only by the process of connecting the connectors.

[0041] Moreover, if Figures 5 to 7 As shown, in another embodiment of the present invention, the second setting portion 300 disposed at the lower portion of the first setting portion 100 is formed by threading the first shell 310 and the second shell 320 .

[0042] A second annular buffer component 450 is provided on the outer side of the extension rod 430 constituting the second connector 400 , and an insertion groove 330 is formed on the inner circumference of the first shell 310 and the second shell 320 so as to insert and fix the outer side of the second buffer component 450 .

[0043] In this case, the second buffer member 450 is made of an elastic material, such as rubber or synthetic rubber, so as to reduce the impact generated when the vehicle is connected.

[0044] On the other hand, a first supporting shoulder 432 is formed at the front end of the extension rod 430 and protrudes outward along the outer circumferential surface. A fixing component 460 is inserted and fixed at the rear of the extension rod 430. A through hole 464 is formed in the center of the fixing component 460 and passes through the front and rear. The through hole 464 is inserted and fixed to the rear of the extension rod 430, and a second supporting shoulder 462 is formed at the rear end and protrudes outward along the outer circumferential surface.

[0045] The first support shoulder 432 supports the entire second buffer component 450 disposed outside the extension rod 430, and the second support shoulder 462 firmly fixes the second buffer component 450 by supporting the rear portion of the second buffer component 450, thereby preventing the second buffer component 450 from moving forward and backward.

[0046] Therefore, the second connector 400 can be stably prevented from being damaged by buffering the impact generated when the vehicle is connected or the impact applied by emergency stop and emergency departure in the connected state.

[0047] Although the preferred embodiments of the present invention are described above, the scope of protection claimed in the present invention is not limited thereto. Ordinary technicians in the technical field to which the present invention belongs can make various modifications without departing from the scope of the idea of ​​the present invention. Therefore, all inventions within the embodiments of the present invention and the equivalent technical scope belong to the scope of protection claimed in the present invention.
