る。Means for solving the problem In order to achieve the above objective, one end of a conductive hose with a conductive wire wound around it is equipped with a connecting part A equipped with a plug receiving connector and a bent pipe, and the other end is connected to the main body of the device. The connecting part B is fitted with a connecting pipe for connecting the hose and is mounted inside a hose cover that can be opened and closed.The connecting part B is designed to protect the fuse from external forces by holding the fuse in a fuse holder integrally formed with the hose cover. One connecting terminal of the two lead wires of the plug with a pin is connected directly to the conductive wire, and the other connecting terminal is connected to the conductive wire via the fuse, and is provided on the hose cover. A guide rib separates the lead wire connection terminal directly connected to the conductive wire and the fuse, which can be attached and detached by opening the hose cover, so that they do not come into contact with each other, and prevents overcurrent from flowing. This allows only the fuse to be replaced even if an overcurrent flows.
