Abstract
A thermal printing head comprises a guide member made in a single-piece and designed as a jumper comprising two superimposed walls, covering, at least partly, respectively and jointly both surfaces of a flexible printed circuit board and providing between them a space for the passage of the support guide wing, enclosed by the flexible printed circuit board, such that the guide member can be elastically nested on the guide wing of the support and provides protection for the flexible printed circuit board in the zone of its junction with the support, and such that, one of the walls of the guide member comprising fingers producing localized elastic pressure on the flexible printed circuit board, an electric contact is provided between the flexible printed circuit board and the support for grounding the printing head via the flexible printed circuit.
