ABSTRACT:
Secondary-power output cable is detachably coupled to an adapter body via a cable connector. The cable connector includes a jack provided on the adapter device and a plug attached to the output cable. The jack and plug have respective engaging mechanisms that cooperate to provide an interlocking mechanism to prevent the output cable from being accidentally decoupled from the adapter body. To provide the interlocking mechanism, the plug has an outward projection formed on the outer surface thereof and the jack has a plug hole for insertion of the plug and an entry recess formed in the inner surface of the jack defining the plug hole, so that the plug can be introduced into the jack only in a particular angular position. The outward projection of the plug is brought into engagement by a locking recessed portion, formed in the inner surface of the jack, by rotating the plug after insertion into the plug hole. This way, a power-supply adapter device is achieved which can be produced with increased productivity at reduced costs and yet is easy to handle.
