BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a terminal device for connecting a terminal of a mobile power cable.

[0002]

2. Description of the Related Art Conventionally, in general, when connecting a high-voltage moving cable of 30 KV or more to indoor wiring, electric equipment, or the like,
An air terminal connection is attached to the moving cable terminal, and connection is made via the air terminal connection.

[0003]

By the way, the above-mentioned conventional aerial terminal connection section has a configuration in which a cable terminal for movement is connected to a lower end in the longitudinal direction of the connection section, and the mobile terminal is pulled out from the connection section. Since the cable portion for use is pulled out directly downward, considerable space is required in consideration of the bending of the cable. Therefore, when installing a high-voltage, large-size mobile cable for testing or construction, when installing the air terminal connection, the air terminal connection must be installed at an extremely high position.
Use on floor equipment in indoor substations where there is not enough height was impossible at first.

Therefore, the present invention solves the above-mentioned conventional problems, and makes it possible to easily attach / detach a mobile cable terminal even in an indoor substation where there is not enough height, and furthermore, foreign matter is involved during connection. It is an object of the present invention to provide a mobile cable terminal connection terminating device that can perform quick emergency processing with high work reliability without fear of occurrence.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a cable connecting portion for detachably connecting a moving cable terminal, and a substantially vertical main body having an air connection terminal at an upper end. And an air terminal connection part integrally formed so that these make a substantially right angle and the cable connection part is directed substantially horizontally at the lower end, and the air terminal connection part is tiltably movable on a bogie. It is attached.

[0006]

In the moving cable terminal connecting terminal device constructed as described above, the moving cable can be connected to the air terminal connecting portion in the horizontal direction, so that the height of the entire connecting device does not increase. It is suitable for use in indoor substations where there is not enough room and height.

[0007] A large-diameter and heavy-weight moving cable can be connected only by slightly tilting the aerial terminal connection portion supported on the carriage so as to be tiltable without lifting the cable to a high position. it can.

If the work of connecting the moving cable and the cable connecting portion is performed by tilting the air terminal connecting portion, the work space on the lower surface of the cable connecting portion is widened, and there is a possibility that foreign matter on the ground may be involved during connection. In addition, the work is easy and the connection work can be performed quickly and with high reliability.
