An adapter for connectors to couple connectors and power supply sockets of different specifications to establish electric connection between them includes two terminal sets that are insertable into the power supply sockets. The two terminal sets are pivotally coupled on one end of the adapter in an opposite open manner, and are held in a housing trough formed on the adapter in normal conditions. When in use desired terminals can be inserted into a corresponding power supply socket of a selected specification and raised upright. The terminal sets can be retracted and extended so that the size of the adapter is smaller. Such a design also can keep the terminals from extending to prevent hurting people or articles.
