ABSTRACT:
An electronic terminal is mechanically and electrically connected to an electronic printer module to form a portable electronic terminal/printer. The bottom housing of the terminal and an extended portion of the bottom housing of the printer module together form a dovetail type connection. The bottom housing of the terminal has a plurality of rails formed thereon and the extended portion of the bottom housing of the printer module has a plurality of channels formed therein for slidably receiving the rails, forming a dovetail type connection. One half of an electrical connector is mounted on the terminal and the other half of the electrical connector is mounted on the printer module in a position to couple when the mechanical dovetail connection is made. A latch mechanism, attached to the extended portion of the bottom housing of the printer secures the bottom housing of the printer and also the two halves of the electrical connector. When the latch mechanism is activated, the electrical connection is broken and the mechanical connection is disengaged.
