Abstract: A mobile terminal has a connector which moves relative to a cover and case. The connector moves through a hole in the case to become electrically coupled to a circuit when the cover is coupled over the case. When the cover is removed, the connector moves to a second position relative to the hole and circuit. The circuit may be an antenna circuit coupled to the cover or another circuit at a different location. An area of the connector is greater than an area of the hole to prevent any components under the connector from being visible when viewed through the hole.
