ABSTRACT:
A safety socket head includes a socket housing which has a first socket slot and a second socket slot parallelly provided thereon, a first shelter which is slidably supported inside the socket housing and positioned below the first socket slot for blocking the first socket slot during a normal condition, a second shelter which is slidably supported inside the socket housing and positioned below the second socket slot for blocking the second socket slot during the normal condition, and a resilient element for retaining the first shelter and the second shelter in the normal condition so as to shelter any undesired substance to intrude into either the first socket slot or the second socket slot. However, when the two plug plates of an electrical plug are inserted into the first and second socket slots simultaneously, the two plug plates drive both the first shelter and the second shelter to slide aside respectively to enable the two plug plates to insert therethrough into the socket body. Moreover, when the two plug plates are detached from the safety socket head, the resilient element inside the socket housing respectively push the first shelter and the second shelter to slide back to the normal condition.
