[0053] It is desirable to insert a portion of the wire (100) and the connecting part (200) into the elastic catch cap to increase the contact area and to catch the wire (100) and the connecting part (200), thereby improving the fixing and supporting force of the wire (100) and the connecting part (200), preventing movement by external force, and cushioning the transmission of shock.

[0054] A transfer cylinder is further fixed to the above fixed plate member (20) by screwing it in, and the plate bracket (31) is fixed to the transfer axis of the above transfer cylinder by screwing it in.

[0055] It is desirable that the position of the plate bracket (31), the lifting support cylinder (32), and the outer protection support tube (50) can be changed to match the position of the wire (100) by driving the above transfer cylinder, and the position of the wire (100) can be changed when the wire (100) is connected to the inner protection support tube (70), thereby making maintenance easier and preventing the wire (100) from getting caught on a vehicle or structure.

[0056] A detection sensor is further fixed to the inner surface of the inner protection support tube (70) by screwing or attaching it, and a transmitter is further fixed to the fixing plate member (20) by screwing it.

[0057] It is desirable that the above detection sensor detects heat and short circuit caused by overheating in the above wire (100) and connection part (200), transmits the detection signal to the above transmitter, and the above transmitter transmits the detection signal to the outside so that rapid maintenance can be performed, prevents fire caused by overheating, and prevents safety accidents caused by short circuit.

[0058] A vibrator is further screw-fastened to the lower horizontal support bar (43) so that the vibration of the vibrator is sequentially transmitted through the lower horizontal support bar (43) to the support cushioning coil spring (44), the outer protective support tube (50), and the wire (100).

[0059] It is desirable to remove moisture and foreign matter adhering to the support cushioning coil spring (44), outer protection support tube (50), and wire (100) by the vibration of the above vibrator, thereby reducing the cost and time associated with maintenance and preventing corrosion caused by moisture, and to prevent the wire (100) from getting caught during the process of connecting and disconnecting it from the airtight cushioning support ring (80).
