[0002] Power supply is currently the most prominent public safety demand, and it is imperative to accelerate the research, development and manufacturing of emergency industry equipment for power supply security.

[0003] At present, the emergency power supply is connected to the 10KV distribution network overhead line through a pole-mounted line emergency power supply device. The fast pole-mounted line emergency power supply device includes a box, an insulator, and a quick socket on the insulator. The insulator passes through the box, and the conductive column outside the insulator is pre-connected with the distribution network overhead line and installed on the pole through a clamp. When the line needs emergency power, the emergency power supply vehicle is connected to the quick socket in the box through a conductive plug. Since the pole-mounted line emergency power supply device is usually outdoors, rainwater enters the box through the gap between the insulator and the box, causing the conductive column to be corroded by humid air and accelerated oxidation, thereby increasing the contact resistance value and the heat generation. Moreover, when the quick socket is connected to the conductive plug, rainwater seeps into the conductive plug and the socket, which will cause the risk of line short circuit. Therefore, the applicant has made a beneficial design and found a solution to the above-mentioned problem. The technical solution to be introduced below is produced in this context.
