Description
Technical Field
The present invention relates to a connector for railway vehicles, and more particularly, to a connector for railway vehicles, which can realize mechanical connection when connecting adjacent railway vehicles, and can quickly and easily connect railway vehicles by connecting an air pipe and an electric wire connection terminal at one time without separately performing air pipe and electric connection.
Background
A railway vehicle runs by connecting a plurality of cars or freight vehicles to the rear end of a leading vehicle generating propulsion power, and a tight-contact type connector as shown in fig. 1 and 2 is generally used to connect the vehicles.
Here, a ring-shaped vehicle body connecting portion 11 is formed at one end portion of the close-contact type connector body 10, the vehicle body connecting portion 11 is used for inserting and fixing a link, the link is in a rod shape and is fixedly installed in a vehicle, a fastener 12 and a fastener insertion groove 13 are formed at the other end portion, and the fastener 12 and the fastener insertion groove 13 have cross sections facing each other at adjacent positions, so that when a pair of connectors to be coupled to the vehicle by the vehicle body connecting portion 11 are coupled to each other and the vehicle is coupled, the fasteners 12 of one side connector are inserted into the fastener insertion grooves 13 of the other side connector, respectively.
Further, since the circular arc-shaped lock groove 12c is formed inside the fastener 12 and the lock member 21 is rotatably provided inside the lock groove 12c, as shown in fig. 2, the lock groove end portions of the fastener inserted into the fastener insertion groove 13 are respectively locked by the upper lock member and prevented from being disengaged, and both vehicles are connected, and the fastener 12 includes: a support portion 12a mounted on an inner wall of the fastener insertion slot 13; and an insertion guide portion 12b integrally formed in a substantially quadrangular pyramid shape in front of the support portion, so that when the fastener 12 is inserted, the locking member 21 elastically supported by the spring 23 is gradually rotated and inserted through the insertion guide portion 12b, and after the insertion is completed, the locking member 21 is restored to an original position by the elastic force of the spring 23 and is placed inside the locking groove 12c, thereby firmly connecting both vehicles.
In this case, when the vehicle is to be separated, the locking portion 21a of the lock member 21 is disengaged from the locking groove 12c by rotating the lock release lever 22 in the arrow direction of fig. 2, and the engaged state is released.
However, the conventional railway vehicle connector is used only for mechanical connection, and cannot connect an air pipe for controlling electrical connection or a pneumatic brake device, and therefore, when a rescue train pulls the failed train by connecting the failed train during operation of the railway vehicle due to an engine failure, the failed train needs to be directly connected to a broadcasting or lighting circuit or other necessary control circuits from the rescue train.
Therefore, since the air piping or electrical connection work becomes cumbersome and takes a lot of time, not only cannot be rapidly driven again, but also the complicated procedure as described above needs to be repeated even at the time of separation, causing inconvenience to passengers when the faulty train is a car.
