As shown, a typical plug 2" of an electrical device may have its prongs (not shown) inserted through the sockets 63' of a waterproof combination 1' of the invention into the slits of the waterproof combination 1' to be electrically connected to the inner prong sections 32' of the waterproof combination 1 '. As a result, the electrical device and the waterproof combination 1' of the invention are electrically connected together. The waterproof combination l' of the invention is adapted to supply rectified voltage (e.g., DC 24 volt) to the electrical device for use or charging because the waterproof combination 1' of the invention has the function of charging due to the provision of the transformer 50'.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
