The periphery of the connection hole is recessed from the outlet body so as to accommodate a part of the plug 2 to form the connection portion 11.

The outlet 1 as described above is protected by being installed in the casing 10 that provides a closed space. The casing 10 has a structure in which the front part thereof is opened so that the connection part 11 of the outlet can be exposed to the front for the plug connection, and the socket 12 is formed along the outer circumference of the connection part 11 of the open end. It protrudes integrally from this casing 10. In addition, a thread is formed on the outer circumferential surface of the socket 12, and a sealing member S1 such as a gasket is provided at an outer circumference of the end of the socket 12 to which the socket 12 and the casing 10 are connected.

The plug 2 is provided with a case 20 which provides a space in which the end of the coated power line (not shown in the drawing) is sealed, and one end thereof is connected to the end of the power line coated in the case 20 and the other end thereof. Includes two terminal rods 22 protruding out of the case. Specifically, according to the embodiment of the present invention, the plug 2 is formed in a cone shape as shown in the case 20 to provide a space where the cable ends are covered with a closed position. The connection part with the cable C at one end of the cone-shaped case 20 has a ring-shaped sealing member S2 having an expanded cross section, for example, a gasket is provided and a cable through hole of the waterproof cap 3 to be described later ( 32) to block the path of moisture penetration.

On the other hand, the waterproof cap 3 is disposed on the cable 2 extending behind the plug 2 as shown in the figure is slid on the cable (2). Specifically, the waterproof cap 3 is a cone-shaped hollow tube that can cover the plug (2) is made of a configuration in which both ends are opened. A thread for forming a connection with the socket 12 is formed on the inner circumferential surface of the large-diameter portion having a relatively large diameter between the two open portions. And the small diameter part side with a small diameter forms the cable through-hole 32 through which a cable penetrates through an opening.
