ABSTRACT:
An electrical connection device for a printing head of a dot printer and a drive circuit therefor, which comprises flexible printed circuits easily connectable to solenoids accommodated in the printing head, and a male connector connected to these circuits. The male connector has electrically conductive pins arranged to be detachably engaged with socket terminals of a female connector fixed to a carriage, the socket terminals being connected to the drive circuit through a flat cable. To mount the printing head onto the carriage, the male connector is plugged into the female connector, while the flexible printed circuits and a flexible hook member are received in a receiving section of the carriage. Disconnection of the printing head from the carriage can be easily made by simply releasing the engagement between the two connectors with the use of the hook member. The flat cable well withstands repetitive bending attributable to reciprocal movement of the printing head.
