ワイヤ印字ヘツド。[Claims for Utility Model Registration] Inside the annular peripheral wall provided with an annular permanent magnet,
a magnet assembly comprising a plurality of electromagnets magnetically coupled to the annular peripheral wall portion and filled with a potting agent for heat dissipation; a plurality of armatures having wires fixed to their tips, the armatures being biased in a direction away from each of the electromagnets by a spring so as to form a magnetic circuit together with the annular peripheral wall and the electromagnets; In a wire printing head that prints with the wire of the armature when the armature is energized and the armature is separated from the electromagnet by the biasing force of the spring, the potting agent of the magnetic assembly is combined with the potting agent. A wire printing head characterized in that the wire printing head is filled with a gap between the wire printing head and the annular peripheral wall.
