Abstract

The monitor screen housing of a CRT type computer terminal forms a monitor module; the base thereof housing the power supply and the electrical interface to other computer equipment forms a base module. The two modules are mechanically and electrically connected to one another in such a way that the monitor module may be supported by and swiveled with respect to the base module and yet may be readily disconnected therefrom. The base module is provided with a raised central region which includes an electrical connector and a circular locking ring having a plurality of horizontally projecting teeth. The monitor module is provided with a recessed central region which includes an electrical connector complementary to that of the base module and a circular locking ring having horizontally projecting teeth that fit between those of the base module only when the base and monitor modules have a predetermined orientation. At least one of the two electrical connectors is permitted to rotate with respect to its corresponding locking ring. When the two modules are disconnected, but oriented above one another with the two teeth of the two rings aligned to fit between one another, the two electrical connectors are also aligned with each other. This assures that, when the monitor module is lowered onto the base module, the two electrical connectors matingly engage at the same time the two locking rings are brought into their operative position.
