Claims

[Claims for Utility Model Registration] 1. A coil body is attached to the outer periphery of a core provided inside a housing body, and a wire for dot printing is attached to the tip of an armature provided close to the tip end surface of the core, In a printer head for a wire dot printer in which the armature is actuated by excitation of the coil body to drive the wire for printing, the coil wire extending from the end of the coil body to the outside thereof is Connect one end of a straight conducting wire with high rigidity, insert the other end of the conducting wire into a hole in a holding plate attached to the outside of the housing body and solder it, and connect the above-mentioned conductive wire between the conducting wire and the coil body. A print head for wire dot printers characterized by a coiled wire with slack. 2. The print head for a wire dot printer according to claim 1, wherein the coil wire is wound around one end of the conductive wire and soldered. 3. The print head for a wire dot printer according to claim 1, wherein the conductive wire is inserted into an insulating tube between one end and the other end of the conductive wire. 4. The print head for a wire dot printer according to claim 1, wherein the conductive wire is an annealed copper wire having a diameter larger than that of the coil wire. 5. The print head for a wire dot printer according to claim 1, wherein the holding plate is a printed circuit board. 6. The housing body holds a permanent magnet, the armature is attached to the housing body, the housing body, the core, and the armature form a magnetic path, and the coil body is magnetized by excitation. 2. The print head for a wire dot printer according to claim 1, wherein the print head is formed so as to cancel the attraction force of the armature to the front end surface of the core caused by the permanent magnet.
