ABSTRACT:
A safety dual plug structure with a primary plug and a secondary plug mounted to an electrical charger is disclosed. The primary plug is provided with a casing rotatably received in a cavity defined in the charger with two prongs mounted thereto for selectively engaging with a first type wall outlet. The primary plug has first terminal members connected to the prongs and extending beyond the casing for selectively engaging with first contacts of the charger. An interior space is defined in the casing for movably receiving a secondary plug. The secondary plug has two blades selectively extend beyond the casing of the primary plug for engaging with a second type wall outlet. The secondary plug has second terminal members shielded in the casing of the primary plug. Openings are formed on the casing of the primary plug for allowing second, resilient contacts of the charger to extend into the casing and electrically engage the second terminal members when the secondary plug is in use. Raised portions are formed on the casing for contacting and preventing the second contacts from entering the casing when the secondary plug is not in use thereby eliminating undesired engagement between the secondary plug and the second contacts of the charger.
